How Long Should a Research Paper Be?

How Long Should A Research Paper Be? An Overview

In short, research paper's average length can range from 1,500 words for research proposals and case studies - all the way to 100,000 words for large dissertations.

Research, by its nature of being complex, requires a careful and thorough elucidation of facts, notions, information, and the like - which is all reflected in its most optimal length.

Thus, one of the critical points that you need to focus on when writing either a complex research paper or a less complex research paper is your objective and how you can relay the latter in a particular context. Say you are writing a book review. Since you will only need to synthesize information from other sources to solidify your claim about a certain topic, you will perhaps use paraphrasing techniques, which offer a relatively lower word count when compared to a full-blown descriptive research paper.

Even when both types of research differ in word counts, they can effectively attain their objectives, given the different contexts in which they are written and constructed. 

Certainly, when asked about how long is a research paper, it surely depends on the objective or the type of research you will be using. Carrying out these objectives will warrant you to do certain paper writing tasks and techniques that are not necessarily long or short when you compare them to other research types. 

At Studyfy, we care for the attainment of your research objectives. We understand that achieving such will contribute to the success of your research completion. While maintaining the ideal word count for a research paper, you are in a meaningful position to understand the various elements that can enrich your paper, even if it looks overwhelming.

How Long Should the Introduction of a Research Paper Be?

The research introduction section most likely occupies approximately 30-40% of the entire research paper.

The introduction of a regular academic paper can total 1750-2000 words depending on the research type and complexity of the research niche or topic. That is why, in writing this section, you must enrich the content of your paper while maintaining readability and coherence for the benefit of your readers.

The introduction houses the background of the study. This is the part of the paper where the entire context of the paper is established. We all know that the research context is important as it helps the readers understand why the paper is even conducted in the first place. Thus, the impression of having a well-established context can only be found in the introduction. Now that we know the gravity of creating a good introduction, let us now ask how long this section should be.

Generally speaking, the paper’s introduction is the longest among all the sections. Aside from establishing the context, the introduction must house the historical underpinnings of the study (important for case studies and ethnographic research), salient information about all the variables in the study (including their relationship with other variables), and related literature and studies that can provide insight into the novelty and peculiarities of the current research project.

To better understand the general composition of your research introduction, you may refer to the breakdown of this section below:

• Context Establishment and Introduction of Key Terms. In this subsection, you will articulate the background (historical, social, economic, psychological, etc.) of the study, including the ecosystem and the niche of your study interest. Furthermore, key terms found as variables in your study must be properly defined operationally and theoretically, if necessary. This comprises 20% of the introduction, or about 350-500 words.
• Related Literature and Studies. This is the subsection where you will criticize and integrate existing literature and studies to highlight the research gap that you intend to fill in. This comprises 25% of the introduction or about 450-600 words.
• Thesis statement. This part of the introduction can only be a paragraph or a couple of sentences, as this needs to be straightforward in relaying the identified research gap of the researchers. This comprises 5% of the introduction or about 90-100 words.
• Objectives or Research Questions. This subsection should outline the aims of the study, especially highlighting the inquiries that concern the relationship between the variables and how the research will progress to fill in the identified gaps. This comprises 5% of the introduction or about 90-100 words.

Theoretical and/or Conceptual Framework. These frameworks, when better assisted with a visual representation, guide the entire research process and provide a structure for understanding the relationship between the variables in the study. This comprises 10% of the introduction or about 180-200 words.

Elements of Good Research Writing Process– While Maintaining the Ideal Word Count!

• Clarity of Purpose . All types of writing, whether long or short, have its clarity of purpose as the heart of the text. In research, it is manifested through the inclusion of a research question or hypothesis. A good research paper does not repeat these elements without a purpose in mind. Though they can be emphasized throughout the development of the paper, the manner of doing it must be in a logical and purposeful way. 

To guide you in writing process of doing so, you can ask yourself the following questions:

• Is the research question or hypothesis clearly stated?
• Does the introduction provide a clear overview of the purpose of the study?
• Does the purpose of the study repeat purposefully in the latter sections of the paper?
• Does the purpose of the study repeat logically in the latter sections of the paper?

2. Literature Review . When appending related literature and studies to your paper, the question must not revolve around whether you have supplied a lot of these pieces of information, making your article wordy and ideal. While the literature review adds a significant ‘chunk’ to your paper, with some paper formats even allotting a specific section for it, we must carefully consider what and how we can integrate them. It subsequently entails a critical analysis of a piece of literature or study and logically places it beside information that you desire to contest. As they say, a good literature review identifies knowledge gaps, highlights the author’s familiarity with the topic, and provides an overview of the research areas that show a disparity of agreement. In order to have these characteristics, you can ask yourself the following questions:

• Have I integrated relevant literature in my review?
• Have I placed it logically within a specific piece of information based on my presumption?
• Do they identify a concept or piece of information that is otherwise unknown to the field?
• Have I critically analyzed existing research to identify the research gap?

3. Logical Flow. Research will not be whole without its parts. Researchers must know how to tie everything together and ensure that each part is functional in itself and supplements with other parts. When dealing with a large body of text, the logical flow of the paper might be a considerable concern. Along with the confusion brought about by the wordiness and complexity of the topic, your readers might get lost because of incoherence and inconsistencies with the presentation of ideas, leading to them not reading your paper any further. Thus, while ensuring that you get the word count that you want, you might want to ask yourself these questions first:

• Does the introduction progress logically from the general background to the specific research question?
• Do the transition devices between sections and individual paragraphs of the body facilitate a smooth flow of ideas?
• Is there a clear hierarchy of ideas, with each paragraph contributing to the overall argument?
• Have I organized ideas in a way that makes the document easy to track?
• Have I pursued a logical sequence of presenting information?

4. Language Use and Style. Developing an academic language throughout your paper and maintaining a formal style of paper writing are all the more important in research writing process, and mind you, it can also help you increase your word count in a sustainable way! Incorporating this form of language and style into your paper entails more than just adding incoherent or overly manufactured words that may be viewed as fillers.

Strategies and known practices are said to hit multiple objectives without compromising the quality of the paper. You may expand your points by providing detailed explanations, introducing sufficient pieces of evidence that supports your claims, addressing counterargument through the presentation of related literature or studies, or clarifying complex concepts through chunking. To better understand these techniques, some of these questions might be helpful for you:

• Is the language clear and concise?
• Have I avoided unnecessary jargon or complex sentences or paragraphs?
• Have I avoided repetition or redundancy in the document?
• Have I expanded on key points by providing more detailed explanations and examples?
• Have I discussed nuances, variations, or exceptions to your results?
• Have I clarified some complex concepts or theories by chunking them into more detailed explanations?

How Long Should a Paragraph Be in a Research Paper?

For the research paper introduction section, a typical paragraph count will be 12-15, excluding the literature review section. Each subsection has 1-2 individual paragraphs. The mentioned section, on the other hand, can have paragraphs totaling 10-20. The conclusion section, on the other hand, is considered ideal if it has 5-7 paragraphs. 

The paragraph count differs from one research type to another and even from one paper section to another. While it is worth deciding how long should a paragraph be in a research paper, it is more important to take note of the importance of ideas that should be included in each paragraph within a certain section. Take the review of the literature section as an example. The number of literature in the paper is said to be equal to the number of paragraphs allotted for the section. The reason lies in the uniformity of importance these pieces of literature hold, provided that they are closely associated with the research gap. 

Do you feel like you need to pay for a research paper in hopes of finding a model article with the right paragraph count? Look no further, as Studyfy has its in-house research paper writing service that houses professionals and experts for your academic paper writing help. Its reasonable price– no deadline markup nor additional hidden charges– is tantamount to the expertise each writer has put into their work.

How Long Should a Conclusion Be in a Research Paper?

A concluding section, then, must only comprise 5% of the total word count of the paper, translating to approximately 400 words. This measly allocation may put you into a flimsy situation, especially if you do not know how to manage your vocabulary well and you keep on adding filler words that can sacrifice the importance of this section. Ditch the nonsense and construct your conclusion in a concise yet enriching way.

In concluding a research paper, it is important to always synthesize the big chunks of information examined in the data analysis and discussion. As worn out as the reader may look after reaching this point, the conclusion must act as a “mellow point” for them, entrusting them only with important pointers of the study. Sometimes, the conclusion part of the paper, even though less wordy than its preceding sections, may be difficult to construct, as you still need to have a basis– a scaffold– to refer to, and synthesizing, just like analyzing and evaluating data, is just as hard and laborious.

Through its superb essay writing services , plus applying top-notch quality assurance to academic papers like research articles, Studyfy can help you achieve the best for last with an effective, meaningful, and content-rich conclusion. Your readers will not think twice about using your study as a model for their own works!

How Long is a Research Paper in terms of its Various Types?

As mentioned in the first part of the article, the word count of an academic paper is dependent on the type of research you wish to conduct. While the general word count has been given, we cannot deny the fact that this threshold is only an estimation. There might be a time when you are tasked to create a research article that is different from a standard IMRAD-structured (Introduction, Methodology, Results, Analysis, Discussion) research paper. You are in for a treat, as we will provide you with a cheat sheet for the word count of several types of write-ups in the realm of research:

Research Proposal

Specific Purpose/s: A preliminary outline that contains the research question, minimal literature review, methodology, and significance of the research undertaking.

"Word Count Range: 1500-3000 words"

Frequently Asked Questions

How long is the introduction in a research paper.

AThe introduction takes up about 30-40% of the entire paper since the context and research background should be specified and further discussed. For a general academic paper with 4000 words, the introduction must be approximately 1500 words. You can do the math for the rest!

How long is a research paper, considering that there are many of them?

There is no one-size-fits-all guideline in determining the word count of a plethora of research papers in the world. Although there is an accepted word count range for each research type (as presented in the previous section), there are several factors that should likewise be considered in determining the word count: specific guidelines set by the institution you are working with, the complexity of the topic, audience, and depth of analysis. 

Do I have to include all of the prescribed subsections of the introduction to increase the word count?

While the prescribed subsections have significant functions in the research paper introduction, some of them are not required to be included. The decisions depend on the type of research you wish to conduct and the external guidelines that you might need to follow. Some disciplines, such as social sciences, require a research article to have a theoretical framework, whereas others do not. Some research papers follow the standard IMRAD paper format that infuses the literature review section into the introduction, while the Germanic Thesis paper format, for example, regards the former as a separate section.

How do I increase my word count without compromising the quality of my research paper?

The dilemma of choosing quality over quantity has long been debunked: you do not have to choose in the first place. All you need is a set of writing strategies and techniques that will target those two birds using one stone. You may provide more detail to some ambiguous or novel terms. You can add additional works of literature to some concepts that promote abstraction. You may include examples or empirical pieces of evidence to create a more concrete representation of a concept or theory. Lastly, you may use subheadings to efficiently allocate word count for your chosen discussion topics.

Why is it important to track the word count of a research paper?

There are various reasons why we need to do it. Some institutions that publish scholarly journals follow certain guidelines in word count as one of the primary requirements. A specified limit enables researchers to allocate the number of words to several sections of their writing efficiently. Most institutions also use paper length as a predictor of publication cost. The longer the word count is, the costlier the publication will be. Lastly, reading engagement is affected by word count, as readers tend to shy away from reading an article that is long, boring, and insubstantial. 

Can a writing service help me achieve my goals of writing within the right word count range?

Certainly! Studyfy offers several academic services, including writing services and research papers for sale . Understanding your various writing needs, writers can cater to the needed style, word count, formatting, and any other aspects so that you can have the best quality write-up without having to fear extra charges and big markups.

The Ideal Length of Research Papers: What’s Right for You?

Research papers are an essential part of the academic experience for many students, yet their ideal length is often contested. This article seeks to address this controversy by providing insight into what constitutes the appropriate and effective length for a research paper. A comprehensive exploration of guidelines from various sources, including university faculty members and leading industry professionals, will be presented in order to provide an informed opinion on this timely issue. Through careful analysis of data points such as word count limits, average document size requirements across institutions, formatting considerations based on style guides (e.g., MLA or APA), it can be determined which approach to research paper writing best serves both learners’ needs and instructors’ expectations. Ultimately, readers should expect a thorough examination that investigates every angle related to finding the “right” amount of content when constructing research papers that are academically sound while still being concisely expressed with precision clarity throughout each paragraph’s text flow.

1. Introduction: Understanding the Research Paper

2. the significance of length in a research paper, 3. traditional academic conventions for research papers, 4. alternatives to longer lengths: shorter formats and writing styles, 5. establishing your own ideal format or style of writing for your research paper, 6. considerations when setting an ideal length for your specific topic and audience, 7. conclusion: finding your optimal balance between brevity and depth.

Research papers are a form of communication between academics, and their purpose is to inform readers about the results of investigations into specific topics. The structure of research papers differs from that of other academic writings; they have an introduction, body sections for findings and discussion, as well as a conclusion.

• Length: Generally speaking, research paper length depends on the scope and complexity of the topic discussed but should usually be between 3-8 pages in total.

This type of writing requires critical thinking skills along with close attention to detail when it comes to data collection. It is essential that researchers take sufficient time outlining what information needs to be collected before beginning any investigation in order to ensure relevant results can be obtained. Additionally, having familiarity with various resources such as journal articles or books related to the topic being studied helps writers develop coherent arguments throughout their work.

The Impact of Length

A research paper’s length plays a critical role in the communication of its findings. Its length often helps determine how comprehensive, detailed and informative it is. Depending on the nature of the subject matter, longer papers may provide more information that can help readers understand complex concepts. In general, they are also seen as providing higher quality evidence since authors have more space to include robust argumentation for their conclusions. Therefore, when writing a research paper one should take into consideration not only what topics will be included but also how many pages are needed to effectively communicate these points.

In terms of determining an appropriate length for a particular project or academic field there is no definitive answer. Generally speaking however most undergraduate-level papers fall between 5–7 pages while graduate-level assignments tend to run 8–10 pages or even longer depending on the specific requirements set by supervisors and/or universities themselves.

The Basics of Academic Research Paper Writing

Research papers are a staple component in the academic world, requiring students to demonstrate their understanding and knowledge gained from courses. The traditional approach for producing an effective research paper is as follows:

• Develop a thesis statement which clearly outlines your argument.
• Identify and use credible sources that align with your argument.

These two components provide the foundation for any successful research paper. It should then be up to you, the writer, to create an effective structure that flows logically between ideas while expanding upon them sufficiently.

As research papers tend to require considerable effort and time, shorter formats can help get your point across quickly. There are a variety of alternative writing styles that you can employ when the length of your paper is restricted.

• Shorter Research Papers: These types of papers typically range from 1-3 pages in length. While there may be less space for arguments and analysis, they still provide enough room for students to effectively present their ideas without becoming bogged down by lengthy word counts or extraneous details.
• Essays: Essay writing provides an excellent opportunity to practice distilling complex information into smaller chunks while conveying key points succinctly. In general, essays should not exceed four pages (double spaced) depending on the course requirements.

Creating Your Own Format or Style of Writing Developing a style of writing that works best for your research paper can be an integral part of the success and impact it will have on readers. As such, you should spend ample time to find your individual format. When crafting your own personal style, some key factors to consider include clarity in language; cohesion among paragraphs and ideas; incorporating visuals effectively as possible (e.g., charts/graphs); properly citing sources; using simple but informative headings; introducing each main topic with a concise sentence or two, followed by bulleted points detailing its importance and implications; avoiding run-on sentences whenever applicable. Additionally, depending on where you are publishing your paper, there may also be specific formatting requirements dictated by publishers (this is especially common when submitting papers for publication). When it comes to length – while varying based on assignment type – general guidelines recommend that undergraduate research papers range from 3-7 pages in length while graduate-level assignments usually require 10+ page lengths.

When setting an ideal length for your topic and audience, it’s important to consider the purpose of your writing. Different types of documents have different lengths that are suitable in terms of scope and content. For example, a blog post can typically be shorter than a research paper or dissertation.

The other key factor is understanding who your target audience is – their expectations about document length will affect how long you should write. As a general rule, it helps to keep things concise by using short sentences and avoiding unnecessary detail where possible. Research papers often vary in length but they usually range from 8-10 pages double spaced; any longer may risk losing readers’ attention.

Achieving the Optimal Balance It can be challenging to determine exactly how much detail or brevity is appropriate for a research paper. The length of your paper will depend on the complexity and scope of your topic, as well as which formatting style you are using (e.g., MLA, APA). Generally speaking, though, most research papers should range from 5-15 pages long in order to adequately explore their topics while still keeping them concise and comprehensible.

• To balance depth with brevity:

When creating a research paper it is essential that you do not sacrifice substance for form; there must always be enough evidence provided within each section to support its assertions and claims. To ensure this without making your document too lengthy, try utilizing different writing techniques such as visual aids like diagrams or charts when presenting complex concepts. Additionally, focus on providing only key points rather than exhaustive details; strive for being succinct yet informative!

In conclusion, the length of research papers can vary greatly depending on a variety of factors. The most important thing is to understand your audience and purpose for writing and tailor your paper accordingly. As long as you are able to properly communicate all relevant information in an organized manner, then there should be no restriction on how long or short your paper needs to be; it all depends on what works best for you!

The “outdated sources” myth

• In-Text Citations
• Reference List
• Research and Publication

In this series, we will look at common APA Style misconceptions and debunk these myths one by one.

We often receive questions about whether sources must have been published within a certain time frame to be cited in a scholarly paper. Many writers incorrectly believe in the “outdated sources” myth, which is that sources must have been published recently, such as the last 5 to 10 years.

However, there is no timeliness requirement in APA Style guidelines (as defined in the Concise Guide to APA Style, Seventh Edition and Publication Manual of the American Psychological Association, Seventh Edition ). Properly citing relevant sources is a key task for writers of any APA Style paper. You should “cite the work of those individuals whose ideas, theories, or research have directly influenced your work. The works you cite provide key background information, support or dispute your thesis, or offer critical definitions and data” (American Psychological Association, 2020, p. 253). We recommend citing reliable, primary sources with the most current information whenever possible.

What it means to be “timely” varies across fields or disciplines. Seminal research articles and/or foundational books can remain relevant for a long time and help establish the context for a given paper. For example, Albert Bandura’s Bobo doll experiment (Bandura et al., 1961) is often cited in contemporary social and child psychology articles. Remember, APA Style has no year-related cutoff.

As always, defer to your instructor’s guidelines when writing student papers. For example, your instructor may require sources be published within a certain timeframe for student papers. If so, follow that guideline for work in that class. Similarly, consider the discipline and audience for whom you are writing. For example, if you are submitting an article to a journal in a fast-developing field like neuroscience, more recent sources—if relevant and important for your readers to consider in the context of your paper—might make your article more competitive.

Now that we’ve debunked another myth, go forth APA Style writers, and cite noteworthy and relevant sources!

• How to write a research paper

Last updated

11 January 2024

Reviewed by

With proper planning, knowledge, and framework, completing a research paper can be a fulfilling and exciting experience. 

Though it might initially sound slightly intimidating, this guide will help you embrace the challenge. 

By documenting your findings, you can inspire others and make a difference in your field. Here's how you can make your research paper unique and comprehensive.

• What is a research paper?

Research papers allow you to demonstrate your knowledge and understanding of a particular topic. These papers are usually lengthier and more detailed than typical essays, requiring deeper insight into the chosen topic.

To write a research paper, you must first choose a topic that interests you and is relevant to the field of study. Once you’ve selected your topic, gathering as many relevant resources as possible, including books, scholarly articles, credible websites, and other academic materials, is essential. You must then read and analyze these sources, summarizing their key points and identifying gaps in the current research.

You can formulate your ideas and opinions once you thoroughly understand the existing research. To get there might involve conducting original research, gathering data, or analyzing existing data sets. It could also involve presenting an original argument or interpretation of the existing research.

Writing a successful research paper involves presenting your findings clearly and engagingly, which might involve using charts, graphs, or other visual aids to present your data and using concise language to explain your findings. You must also ensure your paper adheres to relevant academic formatting guidelines, including proper citations and references.

Overall, writing a research paper requires a significant amount of time, effort, and attention to detail. However, it is also an enriching experience that allows you to delve deeply into a subject that interests you and contribute to the existing body of knowledge in your chosen field.

• How long should a research paper be?

Research papers are deep dives into a topic. Therefore, they tend to be longer pieces of work than essays or opinion pieces. 

However, a suitable length depends on the complexity of the topic and your level of expertise. For instance, are you a first-year college student or an experienced professional? 

Also, remember that the best research papers provide valuable information for the benefit of others. Therefore, the quality of information matters most, not necessarily the length. Being concise is valuable.

Following these best practice steps will help keep your process simple and productive:

1. Gaining a deep understanding of any expectations

Before diving into your intended topic or beginning the research phase, take some time to orient yourself. Suppose there’s a specific topic assigned to you. In that case, it’s essential to deeply understand the question and organize your planning and approach in response. Pay attention to the key requirements and ensure you align your writing accordingly. 

This preparation step entails

Deeply understanding the task or assignment

Being clear about the expected format and length

Familiarizing yourself with the citation and referencing requirements 

Understanding any defined limits for your research contribution

Where applicable, speaking to your professor or research supervisor for further clarification

2. Choose your research topic

Select a research topic that aligns with both your interests and available resources. Ideally, focus on a field where you possess significant experience and analytical skills. In crafting your research paper, it's crucial to go beyond summarizing existing data and contribute fresh insights to the chosen area.

Consider narrowing your focus to a specific aspect of the topic. For example, if exploring the link between technology and mental health, delve into how social media use during the pandemic impacts the well-being of college students. Conducting interviews and surveys with students could provide firsthand data and unique perspectives, adding substantial value to the existing knowledge.

When finalizing your topic, adhere to legal and ethical norms in the relevant area (this ensures the integrity of your research, protects participants' rights, upholds intellectual property standards, and ensures transparency and accountability). Following these principles not only maintains the credibility of your work but also builds trust within your academic or professional community.

For instance, in writing about medical research, consider legal and ethical norms , including patient confidentiality laws and informed consent requirements. Similarly, if analyzing user data on social media platforms, be mindful of data privacy regulations, ensuring compliance with laws governing personal information collection and use. Aligning with legal and ethical standards not only avoids potential issues but also underscores the responsible conduct of your research.

3. Gather preliminary research

Once you’ve landed on your topic, it’s time to explore it further. You’ll want to discover more about available resources and existing research relevant to your assignment at this stage. 

This exploratory phase is vital as you may discover issues with your original idea or realize you have insufficient resources to explore the topic effectively. This key bit of groundwork allows you to redirect your research topic in a different, more feasible, or more relevant direction if necessary. 

Spending ample time at this stage ensures you gather everything you need, learn as much as you can about the topic, and discover gaps where the topic has yet to be sufficiently covered, offering an opportunity to research it further. 

4. Define your research question

To produce a well-structured and focused paper, it is imperative to formulate a clear and precise research question that will guide your work. Your research question must be informed by the existing literature and tailored to the scope and objectives of your project. By refining your focus, you can produce a thoughtful and engaging paper that effectively communicates your ideas to your readers.

5. Write a thesis statement

A thesis statement is a one-to-two-sentence summary of your research paper's main argument or direction. It serves as an overall guide to summarize the overall intent of the research paper for you and anyone wanting to know more about the research.

A strong thesis statement is:

Concise and clear: Explain your case in simple sentences (avoid covering multiple ideas). It might help to think of this section as an elevator pitch.

Specific: Ensure that there is no ambiguity in your statement and that your summary covers the points argued in the paper.

Debatable: A thesis statement puts forward a specific argument––it is not merely a statement but a debatable point that can be analyzed and discussed.

Here are three thesis statement examples from different disciplines:

Psychology thesis example: "We're studying adults aged 25-40 to see if taking short breaks for mindfulness can help with stress. Our goal is to find practical ways to manage anxiety better."

Environmental science thesis example: "This research paper looks into how having more city parks might make the air cleaner and keep people healthier. I want to find out if more green spaces means breathing fewer carcinogens in big cities."

UX research thesis example: "This study focuses on improving mobile banking for older adults using ethnographic research, eye-tracking analysis, and interactive prototyping. We investigate the usefulness of eye-tracking analysis with older individuals, aiming to spark debate and offer fresh perspectives on UX design and digital inclusivity for the aging population."

6. Conduct in-depth research

A research paper doesn’t just include research that you’ve uncovered from other papers and studies but your fresh insights, too. You will seek to become an expert on your topic––understanding the nuances in the current leading theories. You will analyze existing research and add your thinking and discoveries.  It's crucial to conduct well-designed research that is rigorous, robust, and based on reliable sources. Suppose a research paper lacks evidence or is biased. In that case, it won't benefit the academic community or the general public. Therefore, examining the topic thoroughly and furthering its understanding through high-quality research is essential. That usually means conducting new research. Depending on the area under investigation, you may conduct surveys, interviews, diary studies , or observational research to uncover new insights or bolster current claims.

7. Determine supporting evidence

Not every piece of research you’ve discovered will be relevant to your research paper. It’s important to categorize the most meaningful evidence to include alongside your discoveries. It's important to include evidence that doesn't support your claims to avoid exclusion bias and ensure a fair research paper.

8. Write a research paper outline

Before diving in and writing the whole paper, start with an outline. It will help you to see if more research is needed, and it will provide a framework by which to write a more compelling paper. Your supervisor may even request an outline to approve before beginning to write the first draft of the full paper. An outline will include your topic, thesis statement, key headings, short summaries of the research, and your arguments.

9. Write your first draft

Once you feel confident about your outline and sources, it’s time to write your first draft. While penning a long piece of content can be intimidating, if you’ve laid the groundwork, you will have a structure to help you move steadily through each section. To keep up motivation and inspiration, it’s often best to keep the pace quick. Stopping for long periods can interrupt your flow and make jumping back in harder than writing when things are fresh in your mind.

10. Cite your sources correctly

It's always a good practice to give credit where it's due, and the same goes for citing any works that have influenced your paper. Building your arguments on credible references adds value and authenticity to your research. In the formatting guidelines section, you’ll find an overview of different citation styles (MLA, CMOS, or APA), which will help you meet any publishing or academic requirements and strengthen your paper's credibility. It is essential to follow the guidelines provided by your school or the publication you are submitting to ensure the accuracy and relevance of your citations.

11. Ensure your work is original

It is crucial to ensure the originality of your paper, as plagiarism can lead to serious consequences. To avoid plagiarism, you should use proper paraphrasing and quoting techniques. Paraphrasing is rewriting a text in your own words while maintaining the original meaning. Quoting involves directly citing the source. Giving credit to the original author or source is essential whenever you borrow their ideas or words. You can also use plagiarism detection tools such as Scribbr or Grammarly to check the originality of your paper. These tools compare your draft writing to a vast database of online sources. If you find any accidental plagiarism, you should correct it immediately by rephrasing or citing the source.

12. Revise, edit, and proofread

One of the essential qualities of excellent writers is their ability to understand the importance of editing and proofreading. Even though it's tempting to call it a day once you've finished your writing, editing your work can significantly improve its quality. It's natural to overlook the weaker areas when you've just finished writing a paper. Therefore, it's best to take a break of a day or two, or even up to a week, to refresh your mind. This way, you can return to your work with a new perspective. After some breathing room, you can spot any inconsistencies, spelling and grammar errors, typos, or missing citations and correct them. 

• The best research paper format 

The format of your research paper should align with the requirements set forth by your college, school, or target publication. 

There is no one “best” format, per se. Depending on the stated requirements, you may need to include the following elements:

Title page: The title page of a research paper typically includes the title, author's name, and institutional affiliation and may include additional information such as a course name or instructor's name. 

Table of contents: Include a table of contents to make it easy for readers to find specific sections of your paper.

Abstract: The abstract is a summary of the purpose of the paper.

Methods : In this section, describe the research methods used. This may include collecting data , conducting interviews, or doing field research .

Results: Summarize the conclusions you drew from your research in this section.

Discussion: In this section, discuss the implications of your research . Be sure to mention any significant limitations to your approach and suggest areas for further research.

Tables, charts, and illustrations: Use tables, charts, and illustrations to help convey your research findings and make them easier to understand.

Works cited or reference page: Include a works cited or reference page to give credit to the sources that you used to conduct your research.

Bibliography: Provide a list of all the sources you consulted while conducting your research.

Dedication and acknowledgments : Optionally, you may include a dedication and acknowledgments section to thank individuals who helped you with your research.

• General style and formatting guidelines

Formatting your research paper means you can submit it to your college, journal, or other publications in compliance with their criteria.

Research papers tend to follow the American Psychological Association (APA), Modern Language Association (MLA), or Chicago Manual of Style (CMOS) guidelines.

Here’s how each style guide is typically used:

Chicago Manual of Style (CMOS):

CMOS is a versatile style guide used for various types of writing. It's known for its flexibility and use in the humanities. CMOS provides guidelines for citations, formatting, and overall writing style. It allows for both footnotes and in-text citations, giving writers options based on their preferences or publication requirements.

American Psychological Association (APA):

APA is common in the social sciences. It’s hailed for its clarity and emphasis on precision. It has specific rules for citing sources, creating references, and formatting papers. APA style uses in-text citations with an accompanying reference list. It's designed to convey information efficiently and is widely used in academic and scientific writing.

Modern Language Association (MLA):

MLA is widely used in the humanities, especially literature and language studies. It emphasizes the author-page format for in-text citations and provides guidelines for creating a "Works Cited" page. MLA is known for its focus on the author's name and the literary works cited. It’s frequently used in disciplines that prioritize literary analysis and critical thinking.

To confirm you're using the latest style guide, check the official website or publisher's site for updates, consult academic resources, and verify the guide's publication date. Online platforms and educational resources may also provide summaries and alerts about any revisions or additions to the style guide.

Citing sources

When working on your research paper, it's important to cite the sources you used properly. Your citation style will guide you through this process. Generally, there are three parts to citing sources in your research paper: 

First, provide a brief citation in the body of your essay. This is also known as a parenthetical or in-text citation. 

Second, include a full citation in the Reference list at the end of your paper. Different types of citations include in-text citations, footnotes, and reference lists. 

In-text citations include the author's surname and the date of the citation. 

Footnotes appear at the bottom of each page of your research paper. They may also be summarized within a reference list at the end of the paper. 

A reference list includes all of the research used within the paper at the end of the document. It should include the author, date, paper title, and publisher listed in the order that aligns with your citation style.

10 research paper writing tips:

Following some best practices is essential to writing a research paper that contributes to your field of study and creates a positive impact.

These tactics will help you structure your argument effectively and ensure your work benefits others:

Clear and precise language:  Ensure your language is unambiguous. Use academic language appropriately, but keep it simple. Also, provide clear takeaways for your audience.

Effective idea separation:  Organize the vast amount of information and sources in your paper with paragraphs and titles. Create easily digestible sections for your readers to navigate through.

Compelling intro:  Craft an engaging introduction that captures your reader's interest. Hook your audience and motivate them to continue reading.

Thorough revision and editing:  Take the time to review and edit your paper comprehensively. Use tools like Grammarly to detect and correct small, overlooked errors.

Thesis precision:  Develop a clear and concise thesis statement that guides your paper. Ensure that your thesis aligns with your research's overall purpose and contribution.

Logical flow of ideas:  Maintain a logical progression throughout the paper. Use transitions effectively to connect different sections and maintain coherence.

Critical evaluation of sources:  Evaluate and critically assess the relevance and reliability of your sources. Ensure that your research is based on credible and up-to-date information.

Thematic consistency:  Maintain a consistent theme throughout the paper. Ensure that all sections contribute cohesively to the overall argument.

Relevant supporting evidence:  Provide concise and relevant evidence to support your arguments. Avoid unnecessary details that may distract from the main points.

Embrace counterarguments:  Acknowledge and address opposing views to strengthen your position. Show that you have considered alternative arguments in your field.

7 research tips 

If you want your paper to not only be well-written but also contribute to the progress of human knowledge, consider these tips to take your paper to the next level:

Selecting the appropriate topic: The topic you select should align with your area of expertise, comply with the requirements of your project, and have sufficient resources for a comprehensive investigation.

Use academic databases: Academic databases such as PubMed, Google Scholar, and JSTOR offer a wealth of research papers that can help you discover everything you need to know about your chosen topic.

Critically evaluate sources: It is important not to accept research findings at face value. Instead, it is crucial to critically analyze the information to avoid jumping to conclusions or overlooking important details. A well-written research paper requires a critical analysis with thorough reasoning to support claims.

Diversify your sources: Expand your research horizons by exploring a variety of sources beyond the standard databases. Utilize books, conference proceedings, and interviews to gather diverse perspectives and enrich your understanding of the topic.

Take detailed notes: Detailed note-taking is crucial during research and can help you form the outline and body of your paper.

Stay up on trends: Keep abreast of the latest developments in your field by regularly checking for recent publications. Subscribe to newsletters, follow relevant journals, and attend conferences to stay informed about emerging trends and advancements. 

Engage in peer review: Seek feedback from peers or mentors to ensure the rigor and validity of your research . Peer review helps identify potential weaknesses in your methodology and strengthens the overall credibility of your findings.

• The real-world impact of research papers

Writing a research paper is more than an academic or business exercise. The experience provides an opportunity to explore a subject in-depth, broaden one's understanding, and arrive at meaningful conclusions. With careful planning, dedication, and hard work, writing a research paper can be a fulfilling and enriching experience contributing to advancing knowledge.

How do I publish my research paper? 

Many academics wish to publish their research papers. While challenging, your paper might get traction if it covers new and well-written information. To publish your research paper, find a target publication, thoroughly read their guidelines, format your paper accordingly, and send it to them per their instructions. You may need to include a cover letter, too. After submission, your paper may be peer-reviewed by experts to assess its legitimacy, quality, originality, and methodology. Following review, you will be informed by the publication whether they have accepted or rejected your paper. 

What is a good opening sentence for a research paper? 

Beginning your research paper with a compelling introduction can ensure readers are interested in going further. A relevant quote, a compelling statistic, or a bold argument can start the paper and hook your reader. Remember, though, that the most important aspect of a research paper is the quality of the information––not necessarily your ability to storytell, so ensure anything you write aligns with your goals.

Research paper vs. a research proposal—what’s the difference?

While some may confuse research papers and proposals, they are different documents. 

A research proposal comes before a research paper. It is a detailed document that outlines an intended area of exploration. It includes the research topic, methodology, timeline, sources, and potential conclusions. Research proposals are often required when seeking approval to conduct research. 

A research paper is a summary of research findings. A research paper follows a structured format to present those findings and construct an argument or conclusion.

Introduction

The lack of research reproducibility has caused growing concern across various scientific fields [ 1 – 5 ]. Today, there is widespread agreement, within and outside academia, that scientific research is suffering from a reproducibility crisis [ 6 , 7 ]. Researchers reach different conclusions—even when the same data have been processed—simply due to varied analytical procedures [ 8 , 9 ]. As we continue to recognize this problematic situation, some major causes of irreproducible research have been identified. This, in turn, provides the foundation for improvement by identifying and advocating for good research practices (GRPs). Indeed, powerful solutions are available, for example, preregistration of study protocols and statistical analysis plans, sharing of data and analysis code, and adherence to reporting guidelines. Although these and other best practices may facilitate reproducible research and increase trust in science, it remains the responsibility of researchers themselves to actively integrate them into their everyday research practices.

Contrary to ubiquitous specialized training, cross-disciplinary courses focusing on best practices to enhance the quality of research are lacking at universities and are urgently needed. The intersections between disciplines offer a space for peer evaluation, mutual learning, and sharing of best practices. In medical research, interdisciplinary work is inevitable. For example, conducting clinical trials requires experts with diverse backgrounds, including clinical medicine, pharmacology, biostatistics, evidence synthesis, nursing, and implementation science. Bringing researchers with diverse backgrounds and levels of experience together to exchange knowledge and learn about problems and solutions adds value and improves the quality of research.

The present selection of rules was based on our experiences with teaching GRP courses at the University of Zurich, our course participants’ feedback, and the views of a cross-disciplinary group of experts from within the Swiss Reproducibility Network ( www.swissrn.org ). The list is neither exhaustive, nor does it aim to address and systematically summarize the wide spectrum of issues including research ethics and legal aspects (e.g., related to misconduct, conflicts of interests, and scientific integrity). Instead, we focused on practical advice at the different stages of everyday research: from planning and execution to reporting of research. For a more comprehensive overview on GRPs, we point to the United Kingdom’s Medical Research Council’s guidelines [ 10 ] and the Swedish Research Council’s report [ 11 ]. While the discussion of the rules may predominantly focus on clinical research, much applies, in principle, to basic biomedical research and research in other domains as well.

The 10 proposed rules can serve multiple purposes: an introduction for researchers to relevant concepts to improve research quality, a primer for early-career researchers who participate in our GRP courses, or a starting point for lecturers who plan a GRP course at their own institutions. The 10 rules are grouped according to planning (5 rules), execution (3 rules), and reporting of research (2 rules); see Fig 1 . These principles can (and should) be implemented as a habit in everyday research, just like toothbrushing.

GRP, good research practices.

Research planning

Rule 1: specify your research question.

Coming up with a research question is not always simple and may take time. A successful study requires a narrow and clear research question. In evidence-based research, prior studies are assessed in a systematic and transparent way to identify a research gap for a new study that answers a question that matters [ 12 ]. Papers that provide a comprehensive overview of the current state of research in the field are particularly helpful—for example, systematic reviews. Perspective papers may also be useful, for example, there is a paper with the title “SARS-CoV-2 and COVID-19: The most important research questions.” However, a systematic assessment of research gaps deserves more attention than opinion-based publications.

In the next step, a vague research question should be further developed and refined. In clinical research and evidence-based medicine, there is an approach called population, intervention, comparator, outcome, and time frame (PICOT) with a set of criteria that can help framing a research question [ 13 ]. From a well-developed research question, subsequent steps will follow, which may include the exact definition of the population, the outcome, the data to be collected, and the sample size that is required. It may be useful to find out if other researchers find the idea interesting as well and whether it might promise a valuable contribution to the field. However, actively involving the public or the patients can be a more effective way to determine what research questions matter.

The level of details in a research question also depends on whether the planned research is confirmatory or exploratory. In contrast to confirmatory research, exploratory research does not require a well-defined hypothesis from the start. Some examples of exploratory experiments are those based on omics and multi-omics experiments (genomics, bulk RNA-Seq, single-cell, etc.) in systems biology and connectomics and whole-brain analyses in brain imaging. Both exploration and confirmation are needed in science, and it is helpful to understand their strengths and limitations [ 14 , 15 ].

Rule 2: Write and register a study protocol

In clinical research, registration of clinical trials has become a standard since the late 1990 and is now a legal requirement in many countries. Such studies require a study protocol to be registered, for example, with ClinicalTrials.gov, the European Clinical Trials Register, or the World Health Organization’s International Clinical Trials Registry Platform. Similar effort has been implemented for registration of systematic reviews (PROSPERO). Study registration has also been proposed for observational studies [ 16 ] and more recently in preclinical animal research [ 17 ] and is now being advocated across disciplines under the term “preregistration” [ 18 , 19 ].

Study protocols typically document at minimum the research question and hypothesis, a description of the population, the targeted sample size, the inclusion/exclusion criteria, the study design, the data collection, the data processing and transformation, and the planned statistical analyses. The registration of study protocols reduces publication bias and hindsight bias and can safeguard honest research and minimize waste of research [ 20 – 22 ]. Registration ensures that studies can be scrutinized by comparing the reported research with what was actually planned and written in the protocol, and any discrepancies may indicate serious problems (e.g., outcome switching).

Note that registration does not mean that researchers have no flexibility to adapt the plan as needed. Indeed, new or more appropriate procedures may become available or known only after registration of a study. Therefore, a more detailed statistical analysis plan can be amended to the protocol before the data are observed or unblinded [ 23 , 24 ]. Likewise, registration does not exclude the possibility to conduct exploratory data analyses; however, they must be clearly reported as such.

To go even further, registered reports are a novel article type that incentivize high-quality research—irrespective of the ultimate study outcome [ 25 , 26 ]. With registered reports, peer-reviewers decide before anyone knows the results of the study, and they have a more active role in being able to influence the design and analysis of the study. Journals from various disciplines increasingly support registered reports [ 27 ].

Naturally, preregistration and registered reports also have their limitations and may not be appropriate in a purely hypothesis-generating (explorative) framework. Reports of exploratory studies should indeed not be molded into a confirmatory framework; appropriate rigorous reporting alternatives have been suggested and start to become implemented [ 28 , 29 ].

Rule 3: Justify your sample size

Early-career researchers in our GRP courses often identify sample size as an issue in their research. For example, they say that they work with a low number of samples due to slow growth of cells, or they have a limited number of patient tumor samples due to a rare disease. But if your sample size is too low, your study has a high risk of providing a false negative result (type II error). In other words, you are unlikely to find an effect even if there truly was an effect.

Unfortunately, there is more bad news with small studies. When an effect from a small study was selected for drawing conclusions because it was statistically significant, low power increases the probability that an effect size is overestimated [ 30 , 31 ]. The reason is that with low power, studies that due to sampling variation find larger (overestimated) effects are much more likely to be statistically significant than those that happen to find smaller (more realistic) effects [ 30 , 32 , 33 ]. Thus, in such situations, effect sizes are often overestimated. For the phenomenon that small studies often report more extreme results (in meta-analyses), the term “small-study effect” was introduced [ 34 ]. In any case, an underpowered study is a problematic study, no matter the outcome.

In conclusion, small sample sizes can undermine research, but when is a study too small? For one study, a total of 50 patients may be fine, but for another, 1,000 patients may be required. How large a study needs to be designed requires an appropriate sample size calculation. Appropriate sample size calculation ensures that enough data are collected to ensure sufficient statistical power (the probability to reject the null hypothesis when it is in fact false).

Low-powered studies can be avoided by performing a sample size calculation to find out the required sample size of the study. This requires specifying a primary outcome variable and the magnitude of effect you are interested in (among some other factors); in clinical research, this is often the minimal clinically relevant difference. The statistical power is often set at 80% or larger. A comprehensive list of packages for sample size calculation are available [ 35 ], among them the R package “pwr” [ 36 ]. There are also many online calculators available, for example, the University of Zurich’s “SampleSizeR” [ 37 ].

A worthwhile alternative for planning the sample size that puts less emphasis on null hypothesis testing is based on the desired precision of the study; for example, one can calculate the sample size that is necessary to obtain a desired width of a confidence interval for the targeted effect [ 38 – 40 ]. A general framework to sample size justification beyond a calculation-only approach has been proposed [ 41 ]. It is also worth mentioning that some study types have other requirements or need specific methods. In diagnostic testing, one would need to determine the anticipated minimal sensitivity or specificity; in prognostic research, the number of parameters that can be used to fit a prediction model given a fixed sample size should be specified. Designs can also be so complex that a simulation (Monte Carlo method) may be required.

Sample size calculations should be done under different assumptions, and the largest estimated sample size is often the safer bet than a best-case scenario. The calculated sample size should further be adjusted to allow for possible missing data. Due to the complexity of accurately calculating sample size, researchers should strongly consider consulting a statistician early in the study design process.

Rule 4: Write a data management plan

In 2020, 2 Coronavirus Disease 2019 (COVID-19) papers in leading medical journals were retracted after major concerns about the data were raised [ 42 ]. Today, raw data are more often recognized as a key outcome of research along with the paper. Therefore, it is important to develop a strategy for the life cycle of data, including suitable infrastructure for long-term storage.

The data life cycle is described in a data management plan: a document that describes what data will be collected and how the data will be organized, stored, handled, and protected during and after the end of the research project. Several funders require a data management plan in grant submissions, and publishers like PLOS encourage authors to do so as well. The Wellcome Trust provides guidance in the development of a data management plan, including real examples from neuroimaging, genomics, and social sciences [ 43 ]. However, projects do not always allocate funding and resources to the actual implementation of the data management plan.

The Findable, Accessible, Interoperable, and Reusable (FAIR) data principles promote maximal use of data and enable machines to access and reuse data with minimal human intervention [ 44 ]. FAIR principles require the data to be retained, preserved, and shared preferably with an immutable unique identifier and a clear usage license. Appropriate metadata will help other researchers (or machines) to discover, process, and understand the data. However, requesting researchers to fully comply with the FAIR data principles in every detail is an ambitious goal.

Multidisciplinary data repositories that support FAIR are, for example, Dryad (datadryad.org https://datadryad.org/ ), EUDAT ( www.eudat.eu ), OSF (osf.io https://osf.io/ ), and Zenodo (zenodo.org https://zenodo.org/ ). A number of institutional and field-specific repositories may also be suitable. However, sometimes, authors may not be able to make their data publicly available for legal or ethical reasons. In such cases, a data user agreement can indicate the conditions required to access the data. Journals highlight what are acceptable and what are unacceptable data access restrictions and often require a data availability statement.

Organizing the study artifacts in a structured way greatly facilitates the reuse of data and code within and outside the lab, enhancing collaborations and maximizing the research investment. Support and courses for data management plans are sometimes available at universities. Another 10 simple rules paper for creating a good data management plan is dedicated to this topic [ 45 ].

Rule 5: Reduce bias

Bias is a distorted view in favor of or against a particular idea. In statistics, bias is a systematic deviation of a statistical estimate from the (true) quantity it estimates. Bias can invalidate our conclusions, and the more bias there is, the less valid they are. For example, in clinical studies, bias may mislead us into reaching a causal conclusion that the difference in the outcomes was due to the intervention or the exposure. This is a big concern, and, therefore, the risk of bias is assessed in clinical trials [ 46 ] as well as in observational studies [ 47 , 48 ].

There are many different forms of bias that can occur in a study, and they may overlap (e.g., allocation bias and confounding bias) [ 49 ]. Bias can occur at different stages, for example, immortal time bias in the design of the study, information bias in the execution of the study, and publication bias in the reporting of research. Understanding bias allows us researchers to remain vigilant of potential sources of bias when peer-reviewing and designing own studies. We summarized some common types of bias and some preventive steps in Table 1 , but many other forms of bias exist; for a comprehensive overview, see the Oxford University’s Catalogue of Bias [ 50 ].

For a comprehensive collection, see catalogofbias.org .

Here are some noteworthy examples of study bias from the literature: An example of information bias was observed when in 1998 an alleged association between the measles, mumps, and rubella (MMR) vaccine and autism was reported. Recall bias (a subtype of information bias) emerged when parents of autistic children recalled the onset of autism after an MMR vaccination more often than parents of similar children who were diagnosed prior to the media coverage of that controversial and meanwhile retracted study [ 51 ]. A study from 2001 showed better survival for academy award-winning actors, but this was due to immortal time bias that favors the treatment or exposure group [ 52 , 53 ]. A study systematically investigated self-reports about musculoskeletal symptoms and found the presence of information bias. The reason was that participants with little computer-time overestimated, and participants with a lot of computer-time spent underestimated their computer usage [ 54 ].

Information bias can be mitigated by using objective rather than subjective measurements. Standardized operating procedures (SOP) and electronic lab notebooks additionally help to follow well-designed protocols for data collection and handling [ 55 ]. Despite the failure to mitigate bias in studies, complete descriptions of data and methods can at least allow the assessment of risk of bias.

Research execution

Rule 6: avoid questionable research practices.

Questionable research practices (QRPs) can lead to exaggerated findings and false conclusions and thus lead to irreproducible research. Often, QRPs are used with no bad intentions. This becomes evident when methods sections explicitly describe such procedures, for example, to increase the number of samples until statistical significance is reached that supports the hypothesis. Therefore, it is important that researchers know about QRPs in order to recognize and avoid them.

Several questionable QRPs have been named [ 56 , 57 ]. Among them are low statistical power, pseudoreplication, repeated inspection of data, p -hacking [ 58 ], selective reporting, and hypothesizing after the results are known (HARKing).

The first 2 QRPs, low statistical power and pseudoreplication, can be prevented by proper planning and designing of studies, including sample size calculation and appropriate statistical methodology to avoid treating data as independent when in fact they are not. Statistical power is not equal to reproducibility, but statistical power is a precondition of reproducibility as the lack thereof can result in false negative as well as false positive findings (see Rule 3 ).

In fact, a lot of QRP can be avoided with a study protocol and statistical analysis plan. Preregistration, as described in Rule 2, is considered best practice for this purpose. However, many of these issues can additionally be rooted in institutional incentives and rewards. Both funding and promotion are often tied to the quantity rather than the quality of the research output. At universities, still only few or no rewards are given for writing and registering protocols, sharing data, publishing negative findings, and conducting replication studies. Thus, a wider “culture change” is needed.

Rule 7: Be cautious with interpretations of statistical significance

It would help if more researchers were familiar with correct interpretations and possible misinterpretations of statistical tests, p -values, confidence intervals, and statistical power [ 59 , 60 ]. A statistically significant p -value does not necessarily mean that there is a clinically or biologically relevant effect. Specifically, the traditional dichotomization into statistically significant ( p < 0.05) versus statistically nonsignificant ( p ≥ 0.05) results is seldom appropriate, can lead to cherry-picking of results and may eventually corrupt science [ 61 ]. We instead recommend reporting exact p -values and interpreting them in a graded way in terms of the compatibility of the null hypothesis with the data [ 62 , 63 ]. Moreover, a p -value around 0.05 (e.g., 0.047 or 0.055) provides only little information, as is best illustrated by the associated replication power: The probability that a hypothetical replication study of the same design will lead to a statistically significant result is only 50% [ 64 ] and is even lower in the presence of publication bias and regression to the mean (the phenomenon that effect estimates in replication studies are often smaller than the estimates in the original study) [ 65 ]. Claims of novel discoveries should therefore be based on a smaller p -value threshold (e.g., p < 0.005) [ 66 ], but this really depends on the discipline (genome-wide screenings or studies in particle physics often apply much lower thresholds).

Generally, there is often too much emphasis on p -values. A statistical index such as the p -value is just the final product of an analysis, the tip of the iceberg [ 67 ]. Statistical analyses often include many complex stages, from data processing, cleaning, transformation, addressing missing data, modeling, to statistical inference. Errors and pitfalls can creep in at any stage, and even a tiny error can have a big impact on the result [ 68 ]. Also, when many hypothesis tests are conducted (multiple testing), false positive rates may need to be controlled to protect against wrong conclusions, although adjustments for multiple testing are debated [ 69 – 71 ].

Thus, a p -value alone is not a measure of how credible a scientific finding is [ 72 ]. Instead, the quality of the research must be considered, including the study design, the quality of the measurement, and the validity of the assumptions that underlie the data analysis [ 60 , 73 ]. Frameworks exist that help to systematically and transparently assess the certainty in evidence; the most established and widely used one is Grading of Recommendations, Assessment, Development and Evaluations (GRADE; www.gradeworkinggroup.org ) [ 74 ].

Training in basic statistics, statistical programming, and reproducible analyses and better involvement of data professionals in academia is necessary. University departments sometimes have statisticians that can support researchers. Importantly, statisticians need to be involved early in the process and on an equal footing and not just at the end of a project to perform the final data analysis.

Rule 8: Make your research open

In reality, science often lacks transparency. Open science makes the process of producing evidence and claims transparent and accessible to others [ 75 ]. Several universities and research funders have already implemented open science roadmaps to advocate free and public science as well as open access to scientific knowledge, with the aim of further developing the credibility of research. Open research allows more eyes to see it and critique it, a principle similar to the “Linus’s law” in software development, which says that if there are enough people to test a software, most bugs will be discovered.

As science often progresses incrementally, writing and sharing a study protocol and making data and methods readily available is crucial to facilitate knowledge building. The Open Science Framework (osf.io) is a free and open-source project management tool that supports researchers throughout the entire project life cycle. OSF enables preregistration of study protocols and sharing of documents, data, analysis code, supplementary materials, and preprints.

To facilitate reproducibility, a research paper can link to data and analysis code deposited on OSF. Computational notebooks are now readily available that unite data processing, data transformations, statistical analyses, figures and tables in a single document (e.g., R Markdown, Jupyter); see also the 10 simple rules for reproducible computational research [ 76 ]. Making both data and code open thus minimizes waste of funding resources and accelerates science.

Open science can also advance researchers’ careers, especially for early-career researchers. The increased visibility, retrievability, and citations of datasets can all help with career building [ 77 ]. Therefore, institutions should provide necessary training, and hiring committees and journals should align their core values with open science, to attract researchers who aim for transparent and credible research [ 78 ].

Research reporting

Rule 9: report all findings.

Publication bias occurs when the outcome of a study influences the decision whether to publish it. Researchers, reviewers, and publishers often find nonsignificant study results not interesting or worth publishing. As a consequence, outcomes and analyses are only selectively reported in the literature [ 79 ], also known as the file drawer effect [ 80 ].

The extent of publication bias in the literature is illustrated by the overwhelming frequency of statistically significant findings [ 81 ]. A study extracted p -values from MEDLINE and PubMed Central and showed that 96% of the records reported at least 1 statistically significant p -value [ 82 ], which seems implausible in the real world. Another study plotted the distribution of more than 1 million z -values from Medline, revealing a huge gap from −2 to 2 [ 83 ]. Positive studies (i.e., statistically significant, perceived as striking or showing a beneficial effect) were 4 times more likely to get published than negative studies [ 84 ].

Often a statistically nonsignificant result is interpreted as a “null” finding. But a nonsignificant finding does not necessarily mean a null effect; absence of evidence is not evidence of absence [ 85 ]. An individual study may be underpowered, resulting in a nonsignificant finding, but the cumulative evidence from multiple studies may indeed provide sufficient evidence in a meta-analysis. Another argument is that a confidence interval that contains the null value often also contains non-null values that may be of high practical importance. Only if all the values inside the interval are deemed unimportant from a practical perspective, then it may be fair to describe a result as a null finding [ 61 ]. We should thus never report “no difference” or “no association” just because a p -value is larger than 0.05 or, equivalently, because a confidence interval includes the “null” [ 61 ].

On the other hand, studies sometimes report statistically nonsignificant results with “spin” to claim that the experimental treatment is beneficial, often by focusing their conclusions on statistically significant differences on secondary outcomes despite a statistically nonsignificant difference for the primary outcome [ 86 , 87 ].

Findings that are not being published have a tremendous impact on the research ecosystem, distorting our knowledge of the scientific landscape by perpetuating misconceptions, and jeopardizing judgment of researchers and the public trust in science. In clinical research, publication bias can mislead care decisions and harm patients, for example, when treatments appear useful despite only minimal or even absent benefits reported in studies that were not published and thus are unknown to physicians [ 88 ]. Moreover, publication bias also directly affects the formulation and proliferation of scientific theories, which are taught to students and early-career researchers, thereby perpetuating biased research from the core. It has been shown in modeling studies that unless a sufficient proportion of negative studies are published, a false claim can become an accepted fact [ 89 ] and the false positive rates influence trustworthiness in a given field [ 90 ].

In sum, negative findings are undervalued. They need to be more consistently reported at the study level or be systematically investigated at the systematic review level. Researchers have their share of responsibilities, but there is clearly a lack of incentives from promotion and tenure committees, journals, and funders.

Rule 10: Follow reporting guidelines

Study reports need to faithfully describe the aim of the study and what was done, including potential deviations from the original protocol, as well as what was found. Yet, there is ample evidence of discrepancies between protocols and research reports, and of insufficient quality of reporting [ 79 , 91 – 95 ]. Reporting deficiencies threaten our ability to clearly communicate findings, replicate studies, make informed decisions, and build on existing evidence, wasting time and resources invested in the research [ 96 ].

Reporting guidelines aim to provide the minimum information needed on key design features and analysis decisions, ensuring that findings can be adequately used and studies replicated. In 2008, the Enhancing the QUAlity and Transparency Of Health Research (EQUATOR) network was initiated to provide reporting guidelines for a variety of study designs along with guidelines for education and training on how to enhance quality and transparency of health research. Currently, there are 468 reporting guidelines listed in the network; see the most prominent guidelines in Table 2 . Furthermore, following the ICMJE recommendations, medical journals are increasingly endorsing reporting guidelines [ 97 ], in some cases making it mandatory to submit the appropriate reporting checklist along with the manuscript.

The EQUATOR Network is a library with more than 400 reporting guidelines in health research ( www.equator-network.org ).

The use of reporting guidelines and journal endorsement has led to a positive impact on the quality and transparency of research reporting, but improvement is still needed to maximize the value of research [ 98 , 99 ].

Conclusions

Originally, this paper targeted early-career researchers; however, throughout the development of the rules, it became clear that the present recommendations can serve all researchers irrespective of their seniority. We focused on practical guidelines for planning, conducting, and reporting of research. Others have aligned GRP with similar topics [ 100 , 101 ]. Even though we provide 10 simple rules, the word “simple” should not be taken lightly. Putting the rules into practice usually requires effort and time, especially at the beginning of a research project. However, time can also be redeemed, for example, when certain choices can be justified to reviewers by providing a study protocol or when data can be quickly reanalyzed by using computational notebooks and dynamic reports.

Researchers have field-specific research skills, but sometimes are not aware of best practices in other fields that can be useful. Universities should offer cross-disciplinary GRP courses across faculties to train the next generation of scientists. Such courses are an important building block to improve the reproducibility of science.

How To Write A Research Paper

Step-By-Step Tutorial With Examples + FREE Template

By: Derek Jansen (MBA) | Expert Reviewer: Dr Eunice Rautenbach | March 2024

For many students, crafting a strong research paper from scratch can feel like a daunting task – and rightly so! In this post, we’ll unpack what a research paper is, what it needs to do , and how to write one – in three easy steps. 🙂 

Overview: Writing A Research Paper

What (exactly) is a research paper.

• How to write a research paper
• Stage 1 : Topic & literature search
• Stage 2 : Structure & outline
• Stage 3 : Iterative writing
• Key takeaways

Let’s start by asking the most important question, “ What is a research paper? ”.

Simply put, a research paper is a scholarly written work where the writer (that’s you!) answers a specific question (this is called a research question ) through evidence-based arguments . Evidence-based is the keyword here. In other words, a research paper is different from an essay or other writing assignments that draw from the writer’s personal opinions or experiences. With a research paper, it’s all about building your arguments based on evidence (we’ll talk more about that evidence a little later).

Now, it’s worth noting that there are many different types of research papers , including analytical papers (the type I just described), argumentative papers, and interpretative papers. Here, we’ll focus on analytical papers , as these are some of the most common – but if you’re keen to learn about other types of research papers, be sure to check out the rest of the blog .

With that basic foundation laid, let’s get down to business and look at how to write a research paper .

Overview: The 3-Stage Process

While there are, of course, many potential approaches you can take to write a research paper, there are typically three stages to the writing process. So, in this tutorial, we’ll present a straightforward three-step process that we use when working with students at Grad Coach.

These three steps are:

• Finding a research topic and reviewing the existing literature
• Developing a provisional structure and outline for your paper, and
• Writing up your initial draft and then refining it iteratively

Let’s dig into each of these.

Need a helping hand?

Step 1: Find a topic and review the literature

As we mentioned earlier, in a research paper, you, as the researcher, will try to answer a question . More specifically, that’s called a research question , and it sets the direction of your entire paper. What’s important to understand though is that you’ll need to answer that research question with the help of high-quality sources – for example, journal articles, government reports, case studies, and so on. We’ll circle back to this in a minute.

The first stage of the research process is deciding on what your research question will be and then reviewing the existing literature (in other words, past studies and papers) to see what they say about that specific research question. In some cases, your professor may provide you with a predetermined research question (or set of questions). However, in many cases, you’ll need to find your own research question within a certain topic area.

Finding a strong research question hinges on identifying a meaningful research gap – in other words, an area that’s lacking in existing research. There’s a lot to unpack here, so if you wanna learn more, check out the plain-language explainer video below.

Once you’ve figured out which question (or questions) you’ll attempt to answer in your research paper, you’ll need to do a deep dive into the existing literature – this is called a “ literature search ”. Again, there are many ways to go about this, but your most likely starting point will be Google Scholar .

If you’re new to Google Scholar, think of it as Google for the academic world. You can start by simply entering a few different keywords that are relevant to your research question and it will then present a host of articles for you to review. What you want to pay close attention to here is the number of citations for each paper – the more citations a paper has, the more credible it is (generally speaking – there are some exceptions, of course).

Ideally, what you’re looking for are well-cited papers that are highly relevant to your topic. That said, keep in mind that citations are a cumulative metric , so older papers will often have more citations than newer papers – just because they’ve been around for longer. So, don’t fixate on this metric in isolation – relevance and recency are also very important.

Beyond Google Scholar, you’ll also definitely want to check out academic databases and aggregators such as Science Direct, PubMed, JStor and so on. These will often overlap with the results that you find in Google Scholar, but they can also reveal some hidden gems – so, be sure to check them out.

Once you’ve worked your way through all the literature, you’ll want to catalogue all this information in some sort of spreadsheet so that you can easily recall who said what, when and within what context. If you’d like, we’ve got a free literature spreadsheet that helps you do exactly that.

Step 2: Develop a structure and outline

With your research question pinned down and your literature digested and catalogued, it’s time to move on to planning your actual research paper .

It might sound obvious, but it’s really important to have some sort of rough outline in place before you start writing your paper. So often, we see students eagerly rushing into the writing phase, only to land up with a disjointed research paper that rambles on in multiple

Now, the secret here is to not get caught up in the fine details . Realistically, all you need at this stage is a bullet-point list that describes (in broad strokes) what you’ll discuss and in what order. It’s also useful to remember that you’re not glued to this outline – in all likelihood, you’ll chop and change some sections once you start writing, and that’s perfectly okay. What’s important is that you have some sort of roadmap in place from the start.

At this stage you might be wondering, “ But how should I structure my research paper? ”. Well, there’s no one-size-fits-all solution here, but in general, a research paper will consist of a few relatively standardised components:

• Introduction
• Literature review
• Methodology

Let’s take a look at each of these.

First up is the introduction section . As the name suggests, the purpose of the introduction is to set the scene for your research paper. There are usually (at least) four ingredients that go into this section – these are the background to the topic, the research problem and resultant research question , and the justification or rationale. If you’re interested, the video below unpacks the introduction section in more detail. 

The next section of your research paper will typically be your literature review . Remember all that literature you worked through earlier? Well, this is where you’ll present your interpretation of all that content . You’ll do this by writing about recent trends, developments, and arguments within the literature – but more specifically, those that are relevant to your research question . The literature review can oftentimes seem a little daunting, even to seasoned researchers, so be sure to check out our extensive collection of literature review content here .

With the introduction and lit review out of the way, the next section of your paper is the research methodology . In a nutshell, the methodology section should describe to your reader what you did (beyond just reviewing the existing literature) to answer your research question. For example, what data did you collect, how did you collect that data, how did you analyse that data and so on? For each choice, you’ll also need to justify why you chose to do it that way, and what the strengths and weaknesses of your approach were.

Now, it’s worth mentioning that for some research papers, this aspect of the project may be a lot simpler . For example, you may only need to draw on secondary sources (in other words, existing data sets). In some cases, you may just be asked to draw your conclusions from the literature search itself (in other words, there may be no data analysis at all). But, if you are required to collect and analyse data, you’ll need to pay a lot of attention to the methodology section. The video below provides an example of what the methodology section might look like.

By this stage of your paper, you will have explained what your research question is, what the existing literature has to say about that question, and how you analysed additional data to try to answer your question. So, the natural next step is to present your analysis of that data . This section is usually called the “results” or “analysis” section and this is where you’ll showcase your findings.

Depending on your school’s requirements, you may need to present and interpret the data in one section – or you might split the presentation and the interpretation into two sections. In the latter case, your “results” section will just describe the data, and the “discussion” is where you’ll interpret that data and explicitly link your analysis back to your research question. If you’re not sure which approach to take, check in with your professor or take a look at past papers to see what the norms are for your programme.

Alright – once you’ve presented and discussed your results, it’s time to wrap it up . This usually takes the form of the “ conclusion ” section. In the conclusion, you’ll need to highlight the key takeaways from your study and close the loop by explicitly answering your research question. Again, the exact requirements here will vary depending on your programme (and you may not even need a conclusion section at all) – so be sure to check with your professor if you’re unsure.

Step 3: Write and refine

Finally, it’s time to get writing. All too often though, students hit a brick wall right about here… So, how do you avoid this happening to you?

Well, there’s a lot to be said when it comes to writing a research paper (or any sort of academic piece), but we’ll share three practical tips to help you get started.

First and foremost , it’s essential to approach your writing as an iterative process. In other words, you need to start with a really messy first draft and then polish it over multiple rounds of editing. Don’t waste your time trying to write a perfect research paper in one go. Instead, take the pressure off yourself by adopting an iterative approach.

Secondly , it’s important to always lean towards critical writing , rather than descriptive writing. What does this mean? Well, at the simplest level, descriptive writing focuses on the “ what ”, while critical writing digs into the “ so what ” – in other words, the implications . If you’re not familiar with these two types of writing, don’t worry! You can find a plain-language explanation here.

Last but not least, you’ll need to get your referencing right. Specifically, you’ll need to provide credible, correctly formatted citations for the statements you make. We see students making referencing mistakes all the time and it costs them dearly. The good news is that you can easily avoid this by using a simple reference manager . If you don’t have one, check out our video about Mendeley, an easy (and free) reference management tool that you can start using today.

Recap: Key Takeaways

We’ve covered a lot of ground here. To recap, the three steps to writing a high-quality research paper are:

• To choose a research question and review the literature
• To plan your paper structure and draft an outline
• To take an iterative approach to writing, focusing on critical writing and strong referencing

Background: Energy and sports drinks have gained popularity among diverse demographic groups, including adolescents, athletes, workers, and college students. While often used interchangeably, these beverages serve distinct purposes, with energy drinks aiming to boost energy and cognitive performance, and sports drinks designed to prevent dehydration and replenish electrolytes and carbohydrates lost during physical exertion.

Objective: To assess the nutritional quality of energy and sports drinks in Egypt.

Material and Methods: A cross-sectional study assessed the nutrient contents, including energy, sugar, electrolytes, vitamins, and caffeine, of sports and energy drinks available in major supermarkets in Cairo, Alexandria, and Giza, Egypt. Data collection involved photographing all relevant product labels and recording nutritional information. Descriptive statistics and appropriate statistical tests were employed to analyze and compare the nutritional values of energy and sports drinks.

Results: The study analyzed 38 sports drinks and 42 energy drinks. Sports drinks were significantly more expensive than energy drinks, with higher net content and elevated magnesium, potassium, and vitamin C. Energy drinks contained higher concentrations of caffeine, sugars, and vitamins B2, B3, and B6.

Conclusion: Significant nutritional differences exist between sports and energy drinks, reflecting their intended uses. However, these beverages’ high sugar content and calorie loads raise health concerns. Proper labeling, public awareness, and responsible marketing are essential to guide safe consumption practices in Egypt.

Scientists are becoming increasingly frustrated by the time it takes to publish a paper. Something has to change, they say.

When Danielle Fraser first submitted her paper for publication, she had little idea of the painful saga that lay ahead.

She had spent some 18 months studying thousands of fossil species spread across North America from the past 36 million years, and now she had an intriguing result: animal populations were spread widest across latitudes in warm, wet climates. Her work, crucial to earning her PhD at Carleton University in Ottawa, Canada, might be used to make predictions about the response of mammals to climate change — a key question in ecology today. So, with her PhD adviser's encouragement, she sent it to Science in October 2012.

Ten days later, the paper was rejected with a form letter. She sent it to another prestigious journal, the Proceedings of the National Academy of Sciences . Rejected. Next, she tried Ecology Letters . Bounced. “At this point, I definitely was frustrated. I hadn't even been reviewed and I would've loved to know how to improve the paper,” recalls Fraser. “I thought, 'Let's just get it out and go to a journal that will assess the paper'.”

In May 2013, she submitted the paper to Proceedings of the Royal Society B , considered a high-impact journal in her field. The journal sent it out for review — seven months after her initial submission to Science . “Finally!” Fraser thought. What she didn't know was that she had taken only the first steps down the long, bumpy road to publication: it would take another three submissions, two rejections, two rounds of major revisions and numerous drafts before the paper would finally appear. By that point, she could hardly bear to look at it.

Fraser's frustration is widely shared: researchers are increasingly questioning the time it takes to publish their work. Many say that they feel trapped in a cycle of submission, rejection, review, re-review and re-re-review that seems to eat up months of their lives, interfere with job, grant and tenure applications and slow down the dissemination of results. In 2012, Leslie Vosshall, a neuroscientist at the Rockefeller University in New York City, wrote a commentary that lamented the “glacial pace” of scientific publishing 1 . “In the past three years, if anything, it's gotten substantially worse,” she says now. “It takes forever to get the work out, regardless of the journal. It just takes far too long.”

But is the publication process actually becoming longer — and, if so, then why? To find out, Nature examined some recent analyses on time to publication — many of them performed by researchers waiting for their own work to see the light of day — and spoke to scientists and editors about their experiences.

The results contain some surprises. Daniel Himmelstein, a computational-biology graduate student at the University of California, San Francisco, analysed all the papers indexed in the PubMed database that had listed submission and acceptance dates . His study, done for Nature , found no evidence for lengthening delays 2 : the median review time — the time between submission and acceptance of a paper — has hovered at around 100 days for more than 30 years (see 'Paper wait'). But the analysis comes with major caveats. Not all journals — including some high-profile ones — deposit such time-stamp data in PubMed, and some journals show when a paper was resubmitted, rather than submitted for the first time. “Resetting the clock is an especially pernicious issue,” Himmelstein says, and it means that the analysis might be underestimating publication delays.

Some data suggest that wait times have increased within certain subsets of journals, such as popular open-access ones and some of the most sought-after titles. At Nature , the median review time has grown from 85 days to just above 150 days over the past decade, according to Himmelstein's analysis, and at PLoS ONE it has risen from 37 to 125 days over roughly the same period.

Many scientists find this odd, because they expect advances in digital publishing and the proliferation of journals to have sped things up. They say that journals are taking too long to review papers and that reviewers are requesting more data, revisions and new experiments than they used to. “We are demanding more and more unreasonable things from each other,” says Vosshall. Journal editors counter that science itself has become more data-rich, that they work to uphold high editorial and peer-review standards and that some are dealing with increasing numbers of papers. They also say that they are taking steps to expedite the process.

Publication practices and waiting times also vary widely by discipline — with social sciences being notoriously slow. In physics, the pressure to publish fast is reduced because of the common practice of publishing preprints — early versions of a paper before peer review — on the arXiv server . Some of the loudest complaints about publication delays come from those in biological fields, in which competition is fierce and publishing in prestigious journals can be required for career advancement. This month, a group of more than 70 scientists, funders, journal editors and publishers are meeting at the Howard Hughes Medical Institute campus in Chevy Chase, Maryland, to discuss whether biologists should adopt the preprint model to accelerate publishing . “We need a fundamental rethinking of how we do this ,” Vosshall says.

In March 2012, Stephen Royle, a cell biologist at the University of Warwick, UK, started on a publication mission of his own. His latest work answered a controversial question about how cells sense that chromosomes are lined up before dividing, so he first sent it to Nature Cell Biology ( NCB ), because it is a top journal in his field and an editor there had suggested he send it after hearing Royle give a talk. It was rejected without review. Next, he sent it to Developmental Cell . Rejected. His next stop, the Journal of Cell Biology , sent the paper out for review. It came back with a long list of necessary revisions — and a rejection.

Royle and his lab spent almost six months doing the suggested experiments and revising the paper. Then he submitted the updated manuscript to Current Biology . Rejected. EMBO Journal . Reviewed and rejected.

Finally, in December 2012, he submitted it to the Journal of Cell Science ( JCS ), where it was reviewed. One reviewer mentioned that they had already assessed it at another journal and thought that it should have been published then. They wrote that the work was “beautifully conducted, well controlled, and conservatively interpreted”. A second reviewer said that it should not be published. The editor at JCS decided to accept it. The time between first submission to Nature Cell Biology and acceptance at JCS was 317 days. It appeared online another 53 days later 3 . The work went on to win the JCS prize as the journal's top paper for 2013.

Despite the accolade, Royle says that the multiple rejections were demoralizing for his student, who had done the experiments and needed the paper to graduate. He also thinks that the paper deserved the greater exposure that comes from publication in a more prestigious journal. “Unfortunately, the climate at the moment is that if papers aren't in those very top journals, they get overlooked easily,” he says. And Royle, who has done several publication-time analyses and blogged about what he found, has shown that this experience is not unusual. When he looked at the 28 papers that his lab had published in the previous 12 years, the average time to gestate from first submission to publication was the same as a human baby — about 9 months (see go.nature.com/79h2n3 ).

But how much of these delays were his own doing? To publish the chromosome paper, Royle indulged in the all-too-familiar practice of journal shopping: submitting first to the most prestigious journals in his field (often those with the highest impact factor) and then working his way down the hierarchy . ( Nature Cell Biology 's current impact factor is 19; JCS 's is 5.) Journal impact factor or reputation are widely used by scientists and grant-review and hiring committees as a proxy for the quality of the paper. On the flip side, critics say that editors seek out the splashiest papers to boost their publication's impact factor, something that encourages journal shopping, increases rejection rates and adds to the wait time. Journal editors reject this; Ritu Dhand, Nature editorial director in London, says that Nature 's policy of selecting original, important work “may lead to citation impact and media coverage, but Nature editors aren't driven by those considerations”.

How much time does journal shopping add? In the analysis of his group's research papers, Royle found that more than half were shopped around, and that this consumed anywhere from a few days to more than eight months. He went on to analyse all the papers published in 2013 that are indexed in PubMed, and examined whether higher impact factor correlated with longer median publication times. He found an inverted bell-shaped curve — the journals with the lowest and highest impact factors had longer review times than did those in the middle. For the vast majority of those in the middle, review times stood at around 100 days — matching Himmelstein's analysis. Those with the very highest impact factors (30–50) had a review time of 150 days, supporting the idea that pitching a paper to a series of top journals could result in significant delays in publication.

Many scientists, editors and publishers have long acknowledged that journal name is a flawed measure of the quality and value of a piece of research — but the problem shows no signs of going away . “Where your paper is published doesn't say anything about you, your paper's impact or whether it's right or wrong,” says Maria Leptin, director of EMBO, an organization of Europe's leading life scientists and publisher of the EMBO Journal . “Nobody has the courage to say, we, as a funding organization, or we, as a tenure committee, are not going to look at where you publish as opposed to what you publish .”

And the obsession with prestigious journals is just one source of delay — as Fraser, who was battling to publish her paper on ancient animal populations — was about to found out.

Peer review

By October 2013, a full year had passed since Fraser had first submitted her paper to a journal, and she had pretty much stopped caring about impact factor. By this point, the paper had spent two months in review at Proceedings of the Royal Society B , before coming back with mixed reports — and a rejection. So Fraser decided to try PLoS ONE , a journal that says it will publish any rigorous science, regardless of its significance, scope or anticipated citations. It has an impact factor of 3, and a reputation for rapid publication.

PLoS ONE sent the paper out to a single reviewer. Two months later, Fraser got a decision letter that essentially stated that the paper was rejected but might be eligible for re-review if the suggested revisions were made. She made the revisions, adding citations and a small amount of reanalysis. In March 2014, she resubmitted the manuscript, which PLoS ONE sent out to a different reviewer. Another two months passed before she received the new review: major revisions, please.

“I'm just happy they didn't tell me to go away,” recalls Fraser. “I do have e-mails from the time that say, '1-millionth draft'!” She persevered, making more revisions to meet the reviewer's demands, and in June 2014 submitted the paper to PLoS ONE for a third time. Success! The paper 4 was published online 23 months after she had first sent it to Science . The long peer-review and revision process did improve the paper, Fraser says now. “It was really much better.” But did the main conclusion of the paper change? “Not really.”

It takes forever to get the work out, regardless of the journal.

Last year, Chris Hartgerink, a behavioural-sciences graduate student at Tilburg University in the Netherlands, ran an analysis of the Public Library of Science (PLOS) family of journals since the first one launched in 2003. (He chose the journals largely because they make the data easily accessible, and because he was waiting for a paper to be published in PLoS ONE .) He found that the mean review time had roughly doubled in the past decade, from 50–130 days to 150–250 days, depending on the journal (see go.nature.com/s3voeq ). And when Royle looked at eight journals that had published cell-biology papers over the past decade, he found that publication times had lengthened at seven of them, mostly because review times had stretched out.

One contention is that peer reviewers now ask for more. When Ron Vale, a cell biologist at the University of California, San Francisco, analysed biology papers that had been published in Cell , Nature and the Journal of Cell Biology , in the first six months of 1984 and compared that with the same period in 2014, he found that both the average number of authors and the number of panels in experimental figures rose by 2–4 fold 5 . This showed, he argued, that the amount of data required for a publication had gone up, and Vale suspects that much of the added data come from authors trying to meet reviewers' demands. Scientists grumble about overzealous critics who always seem to want more, or different, experiments to nail a point. “It's very rare for the revisions to fundamentally change a paper — the headline doesn't change,” Royle says. His analysis of his group's publication times showed that almost 4 months of the average 9-month gestation was spent revising papers for resubmission.

Many scientists also blame journal editors, who, they say, can be reluctant to provide clear guidance and decisions to authors when reviews are mixed — unnecessarily stringing out the review and revision process. Journal heads disagree, and say that their editors are accomplished at handling mixed reviews. Cell editor-in-chief Emilie Marcus in Cambridge, Massachusetts, says that editors at her journal take responsibility for publication decisions and help authors to map out a plan for revisions.

Technological advances mean that research now involves handling more and more data, editors say, and there is greater emphasis on making that information available to the community. Marcus says that her journal is working to cut review times by, for example, increasing the number of papers that go through only one round of revision — 14% of their papers did so in 2015. In 2009, Cell also restricted the amount of supplemental material that could accompany papers as a way to keep requests for “additional, unrelated experiments” at bay.

PLOS executive editor Veronique Kiermer, based in San Francisco, declined to discuss the specifics of Fraser's paper, but she called its total review time of nine months an “outlier” and said that it was “not ideal to have research being evaluated by a single person”. She acknowledges that PLoS ONE 's publication time has risen; one factor is that the volume of papers has, too — from 200 in 2006 to 30,000 per year now — and it takes time to find and assign appropriate editors and reviewers. (PLOS used 76,000 reviewers in 2015.) Another, says Kiermer, is that the number of essential checkpoints — including competing-interest disclosures, animal-welfare reports and screens for plagiarism — have increased in the past decade. “We'll do everything we can both in terms of technology and looking at workflows to bring these times to publication down,” she says.

Dhand says that at Nature , too, editors find it harder to find reviewers than in the past, “presumably because there are so many more papers that need reviewing”. Himmelstein found that the number of papers in PubMed more than doubled between 2000 and 2015, reaching nearly 1 million articles.

Technology advances

Digital publishing may have had benefits in shortening 'production' time — the time from acceptance to publication — rather than time in review. In Himmelstein's analysis, time spent in production has halved since the early 2000s, falling to a stable median of 25 days.

Several new journals and online publishing platforms have promised to speed up the process even more. PeerJ, a family of journals that launched in 2013, is one of several that now encourage open peer review, in which reviewers' names and comments are posted alongside articles. The hope is that the transparency will prevent unnecessary delays or burdensome revision requests from reviewers.

It's very rare for the revisions to fundamentally change a paper.

The biomedical and life-sciences journal eLife launched in 2012 with a pledge to make initial editorial decisions within a few days and to review papers quickly. Reviewers get strict instructions not to suggest the 'perfect experiment', and they can ask for extra analysis only if it can be completed within 2 months. Otherwise, the paper is rejected. Randy Schekman, a cell biologist at the University of California, Berkeley, and editor-in-chief of eLife , says that these policies mean that more than two-thirds of the journal's accepted papers undergo just one round of review.

In a 2015 analysis, Himmelstein created a ranking by the median review time for all 3,482 journals that had papers with time stamps in the PubMed database from January 2014 to June 2015 (see go.nature.com/sscrr6 ). PeerJ had a relatively fast time: 74 days after submission. At eLife , it took 108 days, and PLoS ONE took 117. By comparison, Cell 's review time was 127 days; Nature 's was 173 days; PLoS Medicine took 177 days; and Developmental Cell was among the slowest of the popular biomedical journals, at 194 days. Marcus notes that comparison between journals is difficult because the publications define received, revised and accepted days differently, and that Developmental Cell places a high priority on timely review.

Preprints reconsidered

One way for biologists to accelerate publication is by embracing preprints. These allow work to quickly receive credit and critique, says Bruno Eckhardt, associate editor of Physical Review E and a theoretical physicist at the University of Marburg in Germany. “It is almost like going on Facebook — it means you are ready to go public,” he says. A preprint submitted to bioRxiv — a server run by Cold Spring Harbor Laboratory in New York — is published online within 24 hours and given a digital object identifier (DOI); subsequent revisions are time-stamped and anyone can read and comment on the paper. “The minute a research story gets into the public domain, it benefits from the collective power of different brains looking at a problem,” says Vale. What's more, proponents say, preprint publishing can simply be added onto the conventional publication process. F1000Research , which launched in 2012, does this by publishing papers first, then inviting open peer review and revision.

Some scientists are going a step further, and using platforms such as GitHub, Zenodo and figshare to publish each hypothesis, data collection or figure as they go along. Each file can be given a DOI, so that it is citable and trackable. Himmelstein, who already publishes his papers as preprints, has been using the Thinklab platform to progressively write up and publish the results of a new project since January 2015. “I push 'publish' and it gets a DOI with no delay,” he says. “Am I really gaining that much by publishing [in a conventional journal]? Or is it better to do what is fastest and most efficient to get your research out there?”

But preprints and real-time digital publishing platforms are no panacea. Vosshall says that many biologists are “terrified” of preprints because they fear getting scooped by competitors or losing credit and intellectual-property rights for their ideas. And even after preprint publishing, scientists can still find themselves slogging through peer review and chasing high-impact journals for a final publication to adorn their CV. Vosshall says that the scientific community relies on conventional journals to serve as a 'prestige filter' so that important papers are brought to the attention of the right readers. Without them, “How do we find the good stuff?” she asks.

For Fraser, her PLoS ONE publication proved a success. When the paper was finally published after its almost-two-year wait, she got positive responses, she says. It has been viewed nearly 2,000 times, had 51 shares on Facebook and Twitter and got 280 downloads. The publication also helped her to secure her current position — as a postdoctoral fellow at the Smithsonian Institution Museum of Natural History in Washington DC. “I pretty much got the top postdoc that I could have gotten.”

Still, the whole process is not something she wants to endure again — so these days, she tends to send her papers to mid-range journals that are likely to publish her work right away. “If my ultimate goal is to get a faculty job, I can't afford to wait two years on a single paper,” she says.

Writing a Research Paper Introduction | Step-by-Step Guide

Published on September 24, 2022 by Jack Caulfield . Revised on March 27, 2023.

The introduction to a research paper is where you set up your topic and approach for the reader. It has several key goals:

• Present your topic and get the reader interested
• Provide background or summarize existing research
• Position your own approach
• Detail your specific research problem and problem statement
• Give an overview of the paper’s structure

The introduction looks slightly different depending on whether your paper presents the results of original empirical research or constructs an argument by engaging with a variety of sources.

Table of contents

Step 1: introduce your topic, step 2: describe the background, step 3: establish your research problem, step 4: specify your objective(s), step 5: map out your paper, research paper introduction examples, frequently asked questions about the research paper introduction.

The first job of the introduction is to tell the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening hook.

The hook is a striking opening sentence that clearly conveys the relevance of your topic. Think of an interesting fact or statistic, a strong statement, a question, or a brief anecdote that will get the reader wondering about your topic.

For example, the following could be an effective hook for an argumentative paper about the environmental impact of cattle farming:

A more empirical paper investigating the relationship of Instagram use with body image issues in adolescent girls might use the following hook:

Don’t feel that your hook necessarily has to be deeply impressive or creative. Clarity and relevance are still more important than catchiness. The key thing is to guide the reader into your topic and situate your ideas.

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

This part of the introduction differs depending on what approach your paper is taking.

In a more argumentative paper, you’ll explore some general background here. In a more empirical paper, this is the place to review previous research and establish how yours fits in.

Argumentative paper: Background information

After you’ve caught your reader’s attention, specify a bit more, providing context and narrowing down your topic.

Provide only the most relevant background information. The introduction isn’t the place to get too in-depth; if more background is essential to your paper, it can appear in the body .

Empirical paper: Describing previous research

For a paper describing original research, you’ll instead provide an overview of the most relevant research that has already been conducted. This is a sort of miniature literature review —a sketch of the current state of research into your topic, boiled down to a few sentences.

This should be informed by genuine engagement with the literature. Your search can be less extensive than in a full literature review, but a clear sense of the relevant research is crucial to inform your own work.

Begin by establishing the kinds of research that have been done, and end with limitations or gaps in the research that you intend to respond to.

The next step is to clarify how your own research fits in and what problem it addresses.

Argumentative paper: Emphasize importance

In an argumentative research paper, you can simply state the problem you intend to discuss, and what is original or important about your argument.

Empirical paper: Relate to the literature

In an empirical research paper, try to lead into the problem on the basis of your discussion of the literature. Think in terms of these questions:

• What research gap is your work intended to fill?
• What limitations in previous work does it address?
• What contribution to knowledge does it make?

You can make the connection between your problem and the existing research using phrases like the following.

Now you’ll get into the specifics of what you intend to find out or express in your research paper.

The way you frame your research objectives varies. An argumentative paper presents a thesis statement, while an empirical paper generally poses a research question (sometimes with a hypothesis as to the answer).

Argumentative paper: Thesis statement

The thesis statement expresses the position that the rest of the paper will present evidence and arguments for. It can be presented in one or two sentences, and should state your position clearly and directly, without providing specific arguments for it at this point.

Empirical paper: Research question and hypothesis

The research question is the question you want to answer in an empirical research paper.

Present your research question clearly and directly, with a minimum of discussion at this point. The rest of the paper will be taken up with discussing and investigating this question; here you just need to express it.

A research question can be framed either directly or indirectly.

• This study set out to answer the following question: What effects does daily use of Instagram have on the prevalence of body image issues among adolescent girls?
• We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls.

If your research involved testing hypotheses , these should be stated along with your research question. They are usually presented in the past tense, since the hypothesis will already have been tested by the time you are writing up your paper.

For example, the following hypothesis might respond to the research question above:

The final part of the introduction is often dedicated to a brief overview of the rest of the paper.

In a paper structured using the standard scientific “introduction, methods, results, discussion” format, this isn’t always necessary. But if your paper is structured in a less predictable way, it’s important to describe the shape of it for the reader.

If included, the overview should be concise, direct, and written in the present tense.

Are cows responsible for climate change? A recent study (RIVM, 2019) shows that cattle farmers account for two thirds of agricultural nitrogen emissions in the Netherlands. These emissions result from nitrogen in manure, which can degrade into ammonia and enter the atmosphere. The study’s calculations show that agriculture is the main source of nitrogen pollution, accounting for 46% of the country’s total emissions. By comparison, road traffic and households are responsible for 6.1% each, the industrial sector for 1%. While efforts are being made to mitigate these emissions, policymakers are reluctant to reckon with the scale of the problem. The approach presented here is a radical one, but commensurate with the issue. This paper argues that the Dutch government must stimulate and subsidize livestock farmers, especially cattle farmers, to transition to sustainable vegetable farming. It first establishes the inadequacy of current mitigation measures, then discusses the various advantages of the results proposed, and finally addresses potential objections to the plan on economic grounds.

The rise of social media has been accompanied by a sharp increase in the prevalence of body image issues among women and girls. This correlation has received significant academic attention: Various empirical studies have been conducted into Facebook usage among adolescent girls (Tiggermann & Slater, 2013; Meier & Gray, 2014). These studies have consistently found that the visual and interactive aspects of the platform have the greatest influence on body image issues. Despite this, highly visual social media (HVSM) such as Instagram have yet to be robustly researched. This paper sets out to address this research gap. We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls. It was hypothesized that daily Instagram use would be associated with an increase in body image concerns and a decrease in self-esteem ratings.

The introduction of a research paper includes several key elements:

• A hook to catch the reader’s interest
• Relevant background on the topic
• Details of your research problem

and your problem statement

• A thesis statement or research question
• Sometimes an overview of the paper

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .

A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis —a prediction that will be confirmed or disproved by your research.

How Long Does Research Take?

How long the research process takes varies by:

• the nature of the assignment
• how well the topic is covered in 'the literature'* (i.e., books, journals and other sources)
• what materials are available in our library or online
• the length of time allotted for the assignment
• the expertise of the researcher (i.e., what you know about the topic).

Things to keep in mind:

• Start early so that you can revise your strategy or your paper if necessary.
• Some topics will have a huge amount of material available, while some will have little.
• If you need background material, subject encyclopedias may give more specific detail.
• Conducting research normally takes longer than you expect.

Frustration and backtracking are a normal part of the process. However, reference librarians can show you strategies that can save you time and can help you do your research more effectively. Ask us for assistance.

You can use the Research Paper Wizard to help plan the sequence and find sources.

*This is the published material about the topic. It is not "literature" as in fiction or drama, although there is literature about the field of literature, too.

What Makes Authority?

Most people who are considered authorities:

• Have studied topic X a long time, and in detail.
• Hold degrees or other credentials that represent that study
• Use sound and reputable research practices
• Work with people who recognize their standing
• Have been cited in the literature of their field(s), and not for their mistakes
• Work at places that have good reputations in that field
• Are better known in their own field(s) than in general. Neil deGrasse Tyson may be an exception to the rule.
• There are exceptions, just as in anything, but this is the way to bet.

When it comes to academic writing, one of the most common questions asked is: How long should a research paper be? This question is essential, as the length can impact not only the scope but also the quality of the paper. In this article, we'll explore various elements that come into play when deciding the length of a research paper. We'll delve into the components, their specific lengths, and the average time required to compile an excellent research paper.

A research paper is a type of academic paper where the author conducts original research on a specific topic, interprets the findings, and then summarizes, argues, or presents the information. This form of academic writing requires in-depth analysis and a thorough literature review to establish credibility and relevance.

The number of pages in a research paper can vary significantly depending on the level of study, subject matter, and specific requirements set by the course or academic journal. High school papers may range from 5-20 pages, college-level papers from 10-30 pages, and graduate theses can be significantly longer, even reaching 100+ pages for Ph.D. dissertations. The spacing, citation style (APA, MLA, Chicago), and number of words also affect the paper's length.

A research paper typically consists of several key components, each with its importance:

• Title Page: The title page includes the paper's title, author's name, and institutional affiliation. This section is generally short but should be formatted according to the relevant citation style.
• Abstract: The abstract provides a concise summary of the research paper, often limited to 150-250 words, depending on the journal or academic requirements.
• Introduction: The intro presents the background, research question, and thesis statement. It sets the context and outlines the main points of the paper.
• Literature Review: This section reviews existing research related to your topic, offering a critical analysis of previous studies and identifying gaps your research aims to fill.
• Methods Section: The methodology details the procedures for collecting and analyzing data. This part should be explicit enough for another researcher to replicate your study.
• Results Section: Here, the findings of the research are presented in a structured manner, often supported by tables and graphs.
• Discussion Section: The discussion interprets the results, linking them to the research question and existing literature. It may also propose areas for future research.
• Conclusion: This section summarizes the main points and restates the thesis in light of the research findings.
• References Section: The references page lists all cited works in the paper, formatted according to the specific citation style being used.
• Appendices: The appendices provide additional data or material that is supplementary but not essential to the main text.

The length of each component depends on the overall length and complexity of the research paper. As a general guideline, the abstract might be 150-250 words, the introduction and conclusion around 10% of the entire paper each, literature review and methodology sections could be a few pages each, and the results and discussion sections might take up the rest of the paper.

The average length of a research paper varies widely depending on the field, level, and journal specifications. However, most academic papers range from 10-20 pages.

The time it takes to write a research paper can vary significantly. For college students or researchers familiar with the topic and the research process, it may take a few weeks. However, if it is your first time, it might take longer, possibly a few months. This time includes researching, writing the first draft, revising, proofreading, and finalizing the paper.

An effective summary, often in the form of an abstract, should include the research question, methodology, main findings, and conclusions. It must be concise while encapsulating the essential aspects of the paper.

The word count for a research paper depends on several factors, such as academic level, field of study, and specific guidelines. However, research papers commonly range from 2,500 to 10,000 words.

That’s why we have brought a series of research writing and addressing different questions related to it. This blog aims to answer queries about the duration your research should ideally take, including insights on how to write an 8-page paper effectively. Although it depends upon the guidelines given by your teacher, there is also a standard length of research writing. Let’s dive in and learn everything about the ideal word count of any research.

Table of Contents

What is a Research Paper?

A research paper is an essay that is based on your investigational work you have completed or will complete on just one or many specific topics of a specific discipline. Research or investigation essays are lengthy depending on the scope and extensive nature of the topic.

It’s just an analysis of the topic from your own perspective. A student or a reader present facts and their theories in front of the audience to inform them about the specific subject matter. If you dont know how long is a research paper, here we will take you on a deeper tour to help you understand these essays thoroughly.

What is the Standard Length of a Research Paper?

Discussing the standard length of a paper, it’s important to note that it varies depending on the specific instructions given to each student and the structural requirements related to their chosen finance research topics . It is never a fixed one for all types of papers yet, there are some conditions and possibilities because of which the word count varies.

Research that has a thesis statement only requires 2 to 3 arguments to be proved and will be summed up in 500 to 700 words. After providing the introduction and a little background on the research, you can directly shift to mentioning the arguments and claims so you may prove the statement and complete the research.

Some research requires detailed analysis and interpretation of the findings. This kind of paper has several stages such as introduction, background, thesis statement, objective, research questions, literature review, research methodology, data collection, discussion, findings, conclusion, and bibliography. Such research easily crosses 5000 words because it is important to discuss everything about the topic.

So it entirely depends upon the structure you are following to write the research. It could be as long as just 500 words, or 5000 words, and even more. It all varies therefore you must be prepared for writing a paper no matter how long it should be.

How long is introduction in research paper?

Many students wonder how long should an introduction be in a research paper? The simple answer to this query is as short as possible that justify the requirements and employ all the methods that are necessary for coveying your message.

Typically, a standard length of introductory paragraph is 300-500 words. If your topic needs more than the standard word count than always ask for suggestion from your professor on first priority. We hope now you know how long should an introduction be for a research paper. 

Why Considering Length of a Research Paper is Important

Identifying the length of research is important because of so many reasons. You might have never realized the significance of considering how long a paper should be, so here we go with some of the vital reasons.

1. Going Extra May Ruin Your Research

You cannot write more than is required in research. If you are doing so then you are automatically ignoring the quality measures of writing a paper. If you are writing more than words than is required then there are chances you are going to submit a poor quality research work.

2. Sticking to the Guidelines is Important

When your guidelines have mentioned 1000 words maximum and you are submitting research of 2000 words, you already know what wrong you have done. If you are not sticking to the guidelines it will result in deduction of marks, fall in grades, and repetition of the class course.

3. Having a Balance is Good

It is necessary to keep a balance between the word count of all the headings. Without this much-needed balance, you might end up submitting a poor paper that has a longer introduction, and a shorter explanation of the findings. That’s why attaining a balance is important in your research word count.

4. Delivering Quality Research is the Criteria

When you are delivering quality content, you will be appreciated no matter what. If you consider the length of your research, you are one step forward in delivering quality research work to your teacher.

How Long Should a Research Paper Be?

This question is valid and one of the frequently asked questions by the students of high school and college. It is also important to know before you start working on your paper. Don’t forget to read the instructions provided by your teacher, however, we have more suggestions for you regarding the length of the research.

1. It All Depends On Your Teacher First

Your teacher indeed decides what should be the ideal length of your research. They have given some guidelines to you and you need to follow them. The teachers always know the best and they will suggest to you how long your essay should be.

Some teachers have kept a certain word limit for the paper while others provide you complete freedom to write as long as you want. It is necessary to figure out what’s best for your research. In high schools, a standard length of any research is a maximum of 7 to 8 pages while the minimum should be 5 pages.

2. Check How Much Length is Required to Justify Your Statement

Sometimes it is based on the  thesis for research paper . From the part of the abstract to the conclusion, there must be a balance between the word count of every heading. It is your responsibility as a writer to track the word count when you are trying to justify your thesis by giving several arguments and claims.

If you have decided how many arguments it will take to prove your thesis, then you have already finalized the length of your research. All you have to do is prepare everything in advance and see if you are proving your point within 5 or 8 pages.

3. It Shouldn’t Miss Any Point

A researcher must be discussing all the standard details that could justify the purpose of writing the paper. It must have all the headings properly discussed. Since all the points must be 100% clear in the research, deciding on a word limit in the very beginning could be a little hard.

But it is not impossible to identify by making an outline and checking how many pages will be covered in writing about a certain topic. All you have to do is take care that no point is missing in the research. Cutting the research short and trying to discuss facts to the exact point won’t help unless you are entirely explaining every aspect as required.

How Long a Research Paper Should be in Words?

You have learned something about the ideal length of research. When it comes to the word count, the criterion is a bit different. For example, if you need a  Ph.D. research paper help , you must know the word count, typically between 70,000 to 80,000 words. As you suggest a specific word count for every heading, it is easier to guess how many words are required to summarize every title.

1. Assign Word Count To Each Heading

It is easier to assign a specific word count to every heading and then see what’s the total word length of the paper. For instance, you have to decide how many words will be used to cover your introduction section. A literature review is a second longer part after the discussion in every research so it is necessary to make an outline in advance and see what is the ideal length of every heading.

By giving a suggested word count to each heading you will make a clear pathway to follow during the complete research. It will be automatically easier for you to see how many words will be written to explain everything in your research thoroughly.

There are several sections in research that require certain word counts. Let’s see what word count is usually subjected to every heading.

An  abstract for a research paper  is the first main part that summarizes the research from the beginning to the conclusion. It contains the thesis, methodology, findings, and conclusion. So to explain the complete research in a few sentences, roughly 100 to 200 words will be required. So you may keep in mind the word count for an abstract is a maximum of 200 words.

● Introduction

An introduction is also a major part of the research and it is easily covered within 300 words maximum. Nothing else is required to explain terminologies or theories in this section.  However, there are many opinion on this topic and each have different answers. That’s the prime reason students spend day and night on google looking for answers on their questions such as how long should introduction be for research paper. In short, 300 to 500 words are more than enough to state your thoughts in an into section and persuade your readers.

● Literature Review

The literature review is the second-longest section in any research. It contains a reference to the past research done in a similar field by other researchers. Every research must have 5 to 8 or even more past papers discussed in it. Therefore the ideal word count for this section is 500 to 1000 words.

● Methodology

The methodology section also has subcategories in which you have to explain the method of research, data collection, population, research implications, research Instrument, etc. It will take around 300 to 400 words and 100 words extra if you are discussing a theoretical framework too.

● Discussion and Interpretation

This is the longest part of any research since you have to explain all the findings and tell your readers how successfully you have managed to prove your thesis. This part is as long as 500 to 1000 or even 1500 words depending upon the results and the explanation required.

● Conclusion

A conclusion is a not so lengthy part of the paper. It is usually done within only 100 or 150 words maximum. It is that simple and thus it doesn’t need so many words to finish the argument and put a full stop.

2. Form a Paper Outline

Forming a paper outline in advance will also help you in understanding how many words you may need to cover every heading. This is one of the best ideas for assigning a particular word count to every heading of the paper.

As you’ll create a paper outline, you will get an instant idea of how many words you have to write in total to complete the research. Following this strategy will surely help you won’t be puzzled later during the writing process.

3. Ask Your Instructor

It is always a good idea to ask your teacher or instructor before following any word count technique. They have assigned you a paper so they can provide you with a better guideline to write your paper. It is the easiest method of identifying the word count of your research as it’s something recommended by an expert. Your job will become much easier and simpler by just seeking advice from your teacher.

How Long a Research Paper Should be for Middle School?

A middle school student is just starting with the research work and they are at the initial stages of learning how to conduct research. To understand how long a paper should be for middle school, you need to do some work.

It could be your teacher or any senior student who will help you and guide how many pages you should write for your research. It is suggested to write 4 to 5 pages when you are a middle school student in writing a paper.

High school is a different stage than middle school. You are mature, better at studies, and even more creative than before. This stage comes with its challenges and one of them is writing the research. If you are a new high school student we bet you don’t know much about paper writing at this level.

When a high school student writes a research paper, it’s usually written within 500 to 1000 words. It could be more than this word count or just 5 to 6 pages. The teacher’s instructions do matter a lot in this aspect and without them, you can’t understand the criteria of research writing. It takes a lot of research, consultation, and creativity to write a paper that stands out. The competition is even tougher in high schools so you know how tough it can get to  write a research paper fast .

Your research will decide if you are going to pass the school or not. Many students stay stuck in a class because they are incapable of submitting a brilliant research paper. Most of the time it’s because they don’t know the standard guidelines for writing a paper.

They usually end up ignoring the pattern, writing incorrect information, or exceeding or limiting the length assigned for the research. So it’s better to keep in mind what is the better approach for research writing and how a high school student can learn to write it.

So how exactly long should research be for college? It starts with roughly 3000 words and goes up to 15000 words. 15000 words is a lot but students who are working on their thesis need a lot of details to justify and complete their research. Without doing this they are not getting passed at any cost so now you know why it is so important.

Different sections of the paper require their particular word count. It is sometimes difficult to identify but your teachers will always be there to guide you. Sometimes students are given the entire freedom to keep their essay length on their own. It helps them understand how easily they can prove their thesis either in a few or a lot of pages.

How Long Should a Literature Review Be?

4-minute read

• 7th October 2023

If you’re writing a research paper or dissertation , then you know how important it is to include a thorough, comprehensive literature review. But exactly how long should your literature review be in relation to the rest of your work? While there’s no one-size-fits-all answer to that question, there are some factors that will help determine the length of your review. In this post, we’ll discuss what information to include in your literature review and how long it should be.

Keep reading to learn more.

What Is a Literature Review?

A literature review is a critical summary and evaluation of the current resources (e.g., books and journal articles) on a specific topic or research question. It is a crucial part of academic writing, such as dissertations, in all categories and fields. Essentially, literature reviews help contextualize your investigations and show how your work is building on existing research.

No matter how long your literature review is, it should generally:

●  Establish context for your research (i.e., provide relevant background information so your reader understands the historical significance of your study ).

●  Identify gaps in the existing literature (such as unaddressed questions or aspects of your topic).

●  Highlight significant concepts related to your topic.

●  Cite relevant studies.

●  Support your argument.

It’s also essential that a literature review critically analyze the sources cited in your study, considering factors such as sample size, research design, and potential biases. Be sure to structure your literature review using the same referencing style as the rest of your research paper (e.g., APA , Chicago , MLA ).

The length of your literature review depends on several factors, including the scope and purpose of your research. In general, the length of the review should be proportionate to your overall paper. For example, if you’re writing a fifty-thousand-word dissertation, then your literature review will likely be an entire chapter comprising about 20 pages. If it’s for a 15-page research paper, your literature review may only be a few pages.

Here are several factors that could affect the length of your literature review:

●  Institutional guidelines : Always check the guidelines provided by your institution or journal (such as an APA journal ). There may be a specific length or word count required for publication.

●  Scope : If your research topic is narrow and focused, your literature review may be shorter. Conversely, if your topic is broad and encompasses a large body of literature, your review may need to be longer.

●  Field of study : Different academic fields may have different expectations regarding the length of literature reviews. For example, literature reviews in the humanities might be longer than those in the natural sciences.

Also, consider your audience. If your literature review is for a general audience or a class assignment, it can probably be shorter and less specialized. However, if it’s for an academic audience in your field of study, you may need to be more thorough and provide an extensive review of the existing literature.

Most literature reviews follow the same basic structure of an introduction, body, and conclusion. Most of the time, they are part of a larger work, so the introduction and conclusion paragraphs will be relatively brief.

However, if the review is a standalone piece, then your introduction and conclusion will be longer since you will need to discuss your research objectives, methods, and findings as well as analyze the literature used in your study.

How old your research sources can be, using the publication date or date of creation as the defining criteria, is either stated in your assignment rubric or depends on your field of study or academic discipline.  If it’s a requirement for your assignment, look for words like “sources must be published in the last 10 years” or words to that effect that specify the publication date or range required.  If the currency of sources is not a requirement of your assignment, think about the course involved and what an appropriate age might be.

How fast-changing is the field of study?

Sources for a history paper might, by their very nature, be older if they are diaries, personal letters, or other documents created long ago and used as primary sources.  Sources used for research in the sciences (health care, nursing, engineering), business and finance, and education and other social science fields require more “cutting edge” research, as these fields change quickly with the acquisition of new knowledge and the need to share it rapidly with practitioners in those fields.

A good rule of thumb is to use sources published in the past 10 years for research in the arts, humanities, literature, history, etc.

For faster-paced fields, sources published in the past 2-3 years is a good benchmark since these sources are more current and reflect the newest discoveries, theories, processes, or best practices.

Use the library’s Multi-Search search results page to limit your sources to those published within a date range you specify.  Use the Publication Date custom setting seen on the left side of the search results page:

Easy navigation table

How Long Should each part of a Research Paper be

Ideally, the most optimal length of a research paper is around 5 pages for short papers and 10 pages for long ones. However, the exact length of your term paper is best determined by your instructor and his instructions.

The same is determined by a number of factors, including the extent and depth of your subject.

Factors Determining the Length of a Paper

The question of how long a research paper should be can be difficult to respond to because it depends on several factors. The most important factors that determine the length of your term paper include;

• The subject of your research
• The number of topics emerging from the subject,
• Number and complexity of the subtopics,
• The magnitude of your findings
• The extent of your discussions and conclusions.

All those factors held constant; it is possible to estimate the length of a less complex research paper if it is demarcated into sections that include the outline, introduction, individual paragraphs, conclusion, and reference page.

Those are the basic components of a typical research paper . Let’s have a look at how long each section should be.

How a Term Paper Outline Should be

An outline is an important part of your research paper. It provides the structure of your paper. It organizes the contents of your term paper into sections.

However, the outline does not contain details about your paper. It only highlights the topics to be covered and the issues to be tackled within those topics.

A format of an outline should include the following;

• An Introduction
• The issue that is being tackled
• A literature review
• Methodology
• Results and discussion
• Conclusion and recommendation

There are brief full-sentence descriptions under the five sections that act as guidelines for your research paper. Therefore, the outline should not exceed 2 pages for short research papers and between 4 to 5 pages for longer papers with 15 to 20 pages.

Let us help you get that A in your next assignment. Place your order today, and you will enjoy the benefits.

Optimal Length of a Research Paper Introduction

As we have noted, the length of your term paper depends on the topic and its contents. This applies to the introduction. For a typical 5-page research paper, your introduction should not exceed half a page.

However, if you are writing a long essay of 15 pages or more, the introduction may span to a page or several paragraphs. Since most of the research papers given to undergraduate college students are not lengthy, the introduction should not exceed a page.

Recommended length of Individual paragraphs in research paper

Even though no definitive rules determine the length of individual paragraphs in a paper, the most recommended length is between 90 words and 130 words. Any paragraph below 90 words is deemed too short to sustain an argument, while one with over 130 words is deemed over-argued.

At the same, it is important to note that the length of the paper determines its length. When the paper is short, then the paragraphs should be short.

If the research paper is long, then the paragraphs should be longer. However, a paragraph should contain more than four sentences. For some topics like childhood obesity , the paragraphs may take longer to incorporate data and statistics in your paper.

Since individual paragraphs should focus on one idea, the length of the paragraph should be determined by the supporting text.

If your idea requires a lot of support in the form of illustrations, examples, statistics, paraphrases, quotes, definitions, causes, and effects, then the paragraph will be longer.

In case the idea presented by the individual paragraph is straightforward and does not require a lot of supporting evidence, then it will be shorter.

How Long Should a Conclusion be

A conclusion is a very important part of your research paper. This is because you, as the author of your paper, are wrapping up everything you have discussed in your paper.

Basically, the length of the conclusion is determined by your paper’s length.

The longer the paper, the longer the conclusion, and the shorter it is, the shorter the conclusion. A conclusion should not be below 3 sentences. It will take a few hours to write all these components of your paper.

Even though this is the case, an effective conclusion should have the following characteristics.

Characteristics of a Good Term Paper Conclusion

• Restatement of the topic of your research
• Restatement of your thesis. This statement should not be identical to what you wrote in the introduction.
• Provide a summary of your main points. Do not provide any new information.
• You can also add up the points to further explain the significance of your points.
• Make a call to action if it is appropriate or significant to your paper.
• Respond to the “so what” question. This requires you to explain the context of your paper and why it matters to the readers.

From this, it is evident that the conclusion is very important in your research paper. You may not include all of the above, but it is important to restate your paper’s topic, thesis, and main points. Check our research paper writing guide to learn more about how to write these parts.

How Long should the Reference Page be?

The reference page length completely depends on the number of sources you have used in your paper. Your paper may be lengthy with few sources, while others can be shorter with more.

A good term paper should have a reference page listing all your information sources. Provided that you list the sources in the right referencing format, like APA and MLA , the length of the reference page is not definitive.

Frequently Asked Questions

How long should a term paper be for high school.

Most teachers in high schools require their students to submit 3 to 5-page research papers. Those are the normal research papers assigned within the semester. However, final research papers like the English 102 papers are between 5 and 7 pages.

What is the optimal graduate paper length?

Even though the topic of the graduate paper determines its length, such papers are considerably longer. This is because they tackle complex topics requiring in-depth explanations, citations, examples, etc. They can be between 7 and 15 pages. They can also exceed the count.

How long should a term paper be for middle school?

The research papers written by students in middle school are considerably shorter than those given to college or graduate school students. The normal papers written within the semester are between 1 and 2 pages, while the final papers are between 2 and 4.

How long should a literature review be for a research paper?

The length of a literature review depends on the purpose and the audience of the term paper. In most of the research papers in college, the literature review should not exceed two pages. For longer papers of more than 10 pages, it can be between 2 and 3 pages.

How to write a term paper fast

To write a research paper fast, begin by selecting a topic. This is followed by researching the topic and working on a thesis. Write the structure of your paper by creating an outline.

Follow the outline and write the paper by beginning with an introduction and ending with a conclusion. Finally, proofread your paper to correct errors. Read our checklist on how to revise your paper to a final copy.

What are the most common types of research paper formats

You must select a specific style when formatting a research or term paper. The most common formats for research papers are MLA, APA, Chicago, and Harvard.

Each format dictates the style of the paper, the spacing, the in-text citation style, and the reference page style. You can get all these done if you get someone to write your homework at a very reasonable cost.

What is the average length of an academic journal article

Most academic journal articles span 20 to 25 pages when they have a one-and-half line spacing. If the academic journals are double-spaced, they can be between 25 and 30 pages. The journal’s word count ranges from 4000 to 7000 words.

What is the normal research paper length.

Research papers are popular for frightening students due to the many hours and hard effort needed. Fortunately, there are several ways to assist you through them. One of them is by understanding the basics, like how to conduct research and the standard length of a research paper.

You’ll discover that if you know the research paper length and how much research you’ll have to do, they’re not that unpleasant to undertake.

In this article, you’ll find the general guidelines for the length of an academic research paper. We’ll also look at the research paper paragraph length and how many pages you can fit your research into.

How many words should a research paper be?

First, let’s begin with the average word count of the research.

How many words are sufficient? A thousand? Or a lot more? To be clear, there’s no general answer specific to all fields. Factors like topics chosen, fields of study, and instructions from an academic professional come into play.

However, a research paper can be between 4000 to 6000 words on average. In some fields, that may get up to 8000 or even more.

How long is a research paper in high school?

How many pages is a research paper in high school? Research papers are often called term papers, and most high school instructors expect their pupils to produce 3 to 5 pages of them.

They are usually given during a semester and sometimes may be up to 5 and 7 pages long if they are final papers.

How long is a short research paper?

A short research paper can be between 2000 to 3000 words long. These are often seen in high school research papers mentioned above. In fewer cases, they can be for college studies.

How long is a research paper: length guide

The length of a research paper varies depending on the stage of education, course of study, and departmental guidelines. In addition, of course, the volume of relevant findings and the length of your conclusion and discussion can also play a part. But these are often personal factors.

However, academic pieces like essays are usually shorter than research papers or theses.

Your research paper assignment will often come with straightforward guidelines on the pages or word count range it is expected to fall within.

For instance, you could be given a paper that should fall between 4500–5000 words or 20–25 pages. If you’re not given a specific range or limit, don’t forget to confirm with your instructor.

A research paper is often divided into:

• Introduction : 15% of the final word count.
• Methods : 35% of the final word count.
• Analysis and Results : 30% of the final word count.
• Discussion : 20% of the final word count.

To answer the question, “how long is a typical research paper?” We intend to look at them through various lenses. The ideal length of a research paper should be up to 8000 words. That means without the references and abstract sections, and you should have over 150 sentences and 30 paragraphs.

Although there are no hard and fast rules for choosing the length of individual paragraphs in a research paper, the most common length is between 90 and 130 words. Any paragraph under 90 words is judged insufficient to support an argument, whereas any paragraph above 130 words is seen as over-inflated.

It is also worth noting that the length of the written piece dictates the paragraph lengths. Therefore, when the document is brief, the paragraphs should be similar and vice versa.

On the other hand, a paragraph should include more than four sentences. This is because some topics in specific fields may require lengthier paragraphs to add facts and statistics to your work. And because every section should concentrate on a single concept, the length of a paragraph should be dictated by its supporting ideas.

For example, if an explanation demands detailed evidence in the form of statistics, illustrations, quotations, examples, and definitions, it would naturally be longer.

However, very brief paragraphs also exist in papers of roughly 2,000 words. These can be frequent and large papers of over 10,000 words. The type of paper and course of study often cause these drastic changes.

The average length of a research paper will always differ because of dissimilar types, structures, topics, and instructions. When giving precise specifications for your research paper length, tailor your research to meet its requirements. Remember to avoid adding irrelevant ideas just to beef up your writing. Stick to concise and rich ideas.

How Long Should the Discussion Section Be? Data from 61,517 Examples

I analyzed a random sample of 61,517 full-text research papers, uploaded to PubMed Central between the years 2016 and 2021, in order to answer the questions:

What is the typical length of a discussion section? and which factors influence it?

I used the BioC API to download the data (see the References section below).

Here’s a summary of the key findings

1. The median discussion section was 1,115 words long (equivalent to 43 sentences, or 7 paragraphs), and 90% of the discussion sections were between 482 and 2,230 words.

2. Compared to other sections in a research paper, the discussion was about the same length as either the methods or the results, and double the length of the introduction .

3. The length of the discussion does not differ between review articles and original research articles .

4. The quality of the journal does not influence the length of the discussion section .

Overall length of the discussion section

Here’s a table that describes the length of a discussion section in terms of words, sentences, and paragraphs:

From these data, we can conclude that the discussion sections in most research papers are between 824 and 1,480 words long (32 to 57 sentences).

If you are interested, here are the links to the articles with the shortest and longest discussion sections.

The discussion section constitutes 29.5% of the total word count in a research article, equivalent to the length of either the methods or the results, and double the length of the introduction [source: How Long Should a Research Paper Be? ].

Length of the discussion for different article types

The following table shows the median word count of the discussion section for different study designs:

The data show no clear pattern since the discussions of review articles and original research articles have almost similar word counts. So we can conclude that there is no particular article type that requires a longer discussion section.

Length of the discussion in different journals

In order to study the influence of the journal quality on the length of the discussion section, I ran a Poisson regression that models the discussion word count given the journal impact factor. Here’s the model output:

The model shows that a higher journal impact factor is associated with a slightly longer discussion section. Although statistically significant, this effect is practically negligible since a 1 unit increase in the journal impact factor is associated with an increase of only 0.1% in the discussion word count. For the median article, this means that a 1 unit increase in the journal impact factor is associated with an approximate increase of 1 word in the discussion section.

How old can references or sources in a thesis be?

I have read that references in scientific papers should be no more than 2-3 years old, since such fields move fast, and no more than 10 years for arts or related fields:

A good rule of thumb is to use sources published in the past 10 years for research in the arts, humanities, literature, history, etc. For faster-paced fields, sources published in the past 2-3 years is a good benchmark since these sources are more current and reflect the newest discoveries, theories, processes, or best practices.

However, I believe that's subjective, so how old is it for a reference to be "too old" to cite?

• online-resource

• 72 There is no "too old to cite". I've actually referenced some of Adolf Fick's and Einstein's original papers in my dissertation. (And they were such fun to read!) Also, that references need to have a certain age is nonsense. Where did you read this? –  user9482 Commented Apr 5, 2019 at 11:54
• 2 @Roland strictly speaking you are right: as written the OP states that a publication must be older than 2 years before you can cite it. However, given the content of the question I suspect that the OP intended to say that a publication must be younger than 2 years. –  Maarten Buis Commented Apr 5, 2019 at 12:01
• 4 No study is too old to cite, but not all studies "age well". Especially in fast paced discipline studies can easily be obsolete. However, this does not mean that all older studies in those disciplines become obsolete, just that many do. You can and should use those non-obsolete older ones. –  Maarten Buis Commented Apr 5, 2019 at 12:07

References can be as old as they need to be to cover the material. I had some that were more than 30 years old. But if all of your references are "old," people are going to want to know why.

You must also be sure you cover the most current research in your field. A few in my own dissertation were for material published in the same year as my own work.

The link given in the comments and the revised question seems to be directed toward undergraduate research assignments, and the "ten years" reference is a part of an example assignment, not a requirement given by the Shapiro Library. The key idea in the link is that references must be "somewhat current."

For a thesis or dissertation, one must cover the field, including both early and very new research.

• 2 Indeed, I suspect that when flipping through a typical issue of a typical journal in most any field, one will find several papers whose references include items listed as "to appear" , or "forthcoming", or "under review", or "submitted", etc. –  Dave L Renfro Commented Apr 5, 2019 at 13:24
• 2 "References can be as old as they need to be" -- while I agree, the link the OP posted suggests that there are assignments saying "Sources must be published in the last 10 years". –  Ingo Commented Apr 5, 2019 at 13:27
• 2 @Ingo Well, yes, but that link seems directed at undergraduate research assignments, and in in fact, that "last ten years" bit is prefaced with, "If it’s a requirement for your assignment..." For a doctoral dissertation, one is expected to cover the field. –  Bob Brown Commented Apr 5, 2019 at 13:31
• 12 Something worth mentioning might be the difference between referencing research results, where you want to try and have relevant recent material, and referencing ideas, which might predate their use in actual research. For example, In my Master's thesis I referenced a pre-1900 paper by Karl Pearson for an idea he discussed that was important for my research, but then referenced modern research papers for my actual implementation. Another example might be natural selection; depending on the context, Darwin is an obvious reference. –  anjama Commented Apr 5, 2019 at 15:05
• 2 When I was an undergraduate in the late 70's we were told about the Science Citation Index, and it was pointed out that "Newton, I" was still being cited. –  Martin Bonner supports Monica Commented Apr 7, 2019 at 7:19

There is no rule about the age of citations. For example in my PhD-thesis I quoted some math-papers from 1600s that were originally written in latin (but those were exceptions).

Much more relavant than the year is the content of a citation and that you cover the relevant literature.

Also, you might want to include a few (relevant!) citations from recent years in order to show that you did your reading not just at the beginning of your thesis and then ignored everything afterwards.

• 6 In math it is common to cite old papers. 1600s is indeed exceptionally old but it is not uncommon to cite 10-100 years old papers. –  Yanko Commented Apr 5, 2019 at 19:22
• 3 I would say that it would be a bit unusual for a math paper to have most of its references under ten years old (unless the authors give only a very brief account of the context and there is only a handful of references in all). –  tomasz Commented Apr 5, 2019 at 20:37
• 2 @Yanko Ten years is old? Jeez, kids today. I doubt I've ever written a paper (including the ones I wrote more than ten years ago) that didn't cite something at least ten years old. –  David Richerby Commented Apr 6, 2019 at 17:58
• But did you really read those papers written in Latin? –  Dubu Commented Apr 8, 2019 at 12:33

I have cited a book on farming by Columella from the 1st century CE .

It provided crucial evidence for the use of a word at that time. But I did not take the evidence as the final say on the matter. I also cited 15th century academic analysis of the evidence as well as 21st century work. There is a fundamental difference between saying

It is true because X says so

X says so, so let us analyse it and cite more recent opinions on whether it is true.

In any discipline it may be necessary to contrast older and younger opinions on the same subject, and you will have to do some work yourself to argue that any given source, whatever its age, is - or is not - reliable.

As it happens, I rejected all the academic analysis and accepted my own interpretation of the original evidence. You as a researcher are expected to determine on a case-by-case basis what evidence needs to be cited, and what can be accepted.

Of course, at some stage, you have to accept that a certain claim is true because X says so. To do this you have to cite something that is fairly recent (which will depend on the discipline) and, if it not the most recent, argue why you are accepting it in preference to the most recent.

Your rule has a large fraction of exception that you should always consider. Make sure you cite the relevant papers for your claims and that you cite the papers which were the first introducing the idea. Don't cite a textbook for ideas just because they are recent. Instead, try to find and cite the original works.

If you cite an idea originating back to Aristoteles it does not make sense to use a recent source. The idea is that old! Also, if you want to prove your claim, that some method was used in the 70s, it's useful to cite papers written in the 70s.

• 2 This hits what I consider the key point. Each citation should be appropriate for its purpose. Documenting the origins of a question is different from documenting the state of the art in a rapidly changing research area. –  Patricia Shanahan Commented Apr 5, 2019 at 22:54

The rule you quote is total nonsense for the sciences, and I have a hard time taking it seriously for the humanities.

You cite whatever you need to cite, regardless of its age. Typically, if you're referring to something that is decades old, it's now either common knowledge (e.g., Newton's laws) so probably doesn't need citation at all, or it's in textbooks (which are probably more appropriate to cite than the original source). Both of those things are a consequence of age but age per se is a completely spurious reason to not cite something.

• 2 In the humanities it's outright laughable. Besides the fact that often our sources are necessarily quite a bit older (classicists will quote stuff from antiquity, medievalists from the medieval, etc, historians from their period of history), many things we study may only be taken up by someone every few years or decades even, so to even do a cursory review of prior work you're going to be citing old stuff unless you're on a very popular topic. –  user0721090601 Commented Apr 7, 2019 at 14:03
• 2 @guifa That's what I figured, but I was waiting for somebody else to say it, since "Scientist guesses what the humanities are like" is probably pretty laughable, too! –  David Richerby Commented Apr 7, 2019 at 15:16

A group of researchers published this very interesting paper:

The nearly universal link between the age of past knowledge and tomorrow’s breakthroughs in science and technology: The hotspot

From a pure data science perspective, they try to understand how the distribution of reference age affects the forward citations of an article. They analyze all publications (~ 28 million) in Web of Science published between 1945 - 2013.

Unfortunately, they do not show an aggregated histogram of age differences between a publication and its references. But in Fig. 1 we see the mean (0-50 years) and variance (0-4) for all published papers and it is all over the place. So the take away might be to cite what you want.

However, they echo in their paper the comments and answers that you got here. Impactful and hopefully good research seems to differ from the "cite what you want" approach. If you want to increase the likelihood of your work having an impact you should base your work on recent advances but also be aware of well-established theories or overlooked ideas from the past. They show this in the paper by finding a hotspot of highly cited papers that have a low mean age distance to their references but a high variance in age distance.

Here is a link to the paper (super interesting): http://advances.sciencemag.org/content/advances/3/4/e1601315.full.pdf

There's no limit on how old they can be. In biology people often cite Darwin (1859) and geneticists who work on pedigrees can cite government records from hundreds of years ago. Work involving theology may cite the Bible. Historians cite original documents from thousands of years ago. Sometimes a fun game is to see what the oldest citation you can get away with is. Plato or Aristotle is often a safe bet.

Generally, you are supposed to cite the oldest paper that made a discovery, as the credit belongs to them. When in doubt, you can cite one old and one new paper.

However, your work must be in the context of contemporary scientific literature. If you cite a 50 year old paper for a theory, you better make sure the theory has not been disproven in another paper published 30 years after. If you say the state of the art in a field is a paper published 10 years ago, it would look really bad if somebody brought up a 5 year old paper that advanced it further. This is why citing old material is risky: You can't easily tell that it's still current. If a paper came out last monday, chances are pretty low that somebody refuted it in that time.

• I'm sorry but this is terrible. You seem to be advocating not citing older work that you use, purely to avoid the embarrasment of being out of date. That's what you literature search is supposed to avoid. If you're using the 50-year-old theory, you need to cite something for it. If that theory has been refuted, you're going to look like an idiot whether you cite the original paper or not. If you're out-of-date on the state of the art, you need to find out what it really is. And that paper that came out last Monday also hasn't had time for anyone to check that it seems to be true! –  David Richerby Commented Apr 6, 2019 at 17:55
• @DavidRicherby I'm sorry but your comment is terrible. You seem to have confused a number of points. Notable among them is your mistaking numbers given as examples for actual universal rules. I'd recommend re-reading the post carefully. If you still have questions, I'd be happy to respond to them if you phrase it in a more constructive manner. –  Trusly Commented Apr 8, 2019 at 4:19
• I've re-read your answer and I stand by what I wrote. I'm not criticizing the numbers at all. I'm criticizing what appears to be a recommendation to avoid citing old stuff because it might be out of date and your literature search might have failed to spot that. If that's not what you meant, what did you mean? –  David Richerby Commented Apr 8, 2019 at 8:41
• @DavidRicherby I didn't say to avoid citing old stuff because it might be out of date. I said that when citing old material, it is especially important to make sure it's not obsolete. –  Trusly Commented Apr 9, 2019 at 19:47

To be honest, just like you’ve said, all of this is quite subjective... Personally, I believe that if a paper is relevant to the point you are trying to make and hasn’t been categorically disproven then it’s fair game. However, what I think is irrelevant; it depends on the person marking your dissertation and how they feel about it. Some academics I know don’t care while others do. I was once marked down for using a 7 year old paper as a reference even though it was very relevant to my work, simply because the lecturer marking my work didn’t want to see anything older than 5 years.

For the most part, it should be fine. Academics who insist on only recent papers are few, in my experience.

Research data – how long should it be kept.

Researchers are tasked with collecting, storing and the retention of research data beyond the completion of their research project. Do you know exactly how long you should retain your research data? Carmela Gallo from the University of Melbourne’s Legal and Risk team offers key advice on research data management for researchers.

According to Management of Data and Information in Research: A guide supporting the Australian Code for the Responsible Conduct of Research (2.3 Storage, retention and disposal),

“The period for which data should be retained should be determined by prevailing standards for the specific type of research and any applicable state, territory or national legislation. In general, the minimum period for retention of research data is 5 years from the date of publication.”

However, researchers should not be misled in believing that all research data retention period requirements are 5 years from the date of publication based on the above statement. As a researcher at the University of Melbourne, you need to be aware that the University of Melbourne Records Retention & Disposal Authority provides the legal mechanism for the retention and disposal of university records in accordance with the Victorian Public Records Act 1973. This includes research data.

By applying the disposal classes to your research data, you will be meeting your compliance obligation.  Below is a summary of the retention periods for research data from the University of Melbourne Records and Retention Disposal Authority

3.2 : Datasets of regulatory or community-wide significance

Includes data created that is:

• part of genetic research, including gene therapy
• controversial or of high public interest,
• costly or impossible to reproduce
• relates to the use of an innovative technique for the first time,
• of significant community or heritage value to the state or nation
• required by funding or other agreements to be retained permanently

3.3 Datasets from clinical trials

Temporary – Minimum 15 years after completion of research activity

3.4 Datasets from involving minors

Temporary – Minimum 15 years after the child reaches the age of 18

3.5 Datasets not involving clinical trials or minors

Temporary – Minimum 5 years after completion of research activity

… under certain circumstances

However, under certain circumstances, there may be other factors that will override these retention periods for research data. Below are two examples:

• Are there legal requirements by funders such as government bodies and publishers that require a different retention period than those specified in the University Retention and Disposal authority? If so, is this well documented?
• The University has recently adopted a set of  open access principles that encourages sharing of data (if appropriate) beyond its publication. If you decided to put your research on open access, consider how long does the research data need to be made accessible and why? The retention period and justification should be documented.

Researchers will need to consider regulatory responsibilities, ethical, legal, cultural and other guidelines when determining how long to retain research data. The University of Melbourne Records Retention and Disposal Authority is one of those guidelines. From a records perspective, it is important that researchers determine and document the retention and disposal requirements from the beginning. It is important that this information is readily available into the future.

Microplastics Are Everywhere. Here’s How to Avoid Eating Them.

By Katie Okamoto

Katie Okamoto is an editor focused on the environment. She has covered the intersection of products and sustainability for more than a decade.

Microplastics and nanoplastics are everywhere.

The teeny tiny pieces of plastic have been found in everything from drinking water to chicken nuggets, apples, and broccoli.

Recent studies have linked these pollutants to heart disease , lung disorders , and more worrying health issues.

But unfortunately, microplastics are now so pervasive that they’re nearly impossible to avoid.

If you’re concerned about the health effects linked to microplastics, the experts I spoke with said that you can lower your risk by taking care of your general health: getting plenty of sleep and exercise, eating a balanced diet, lowering stress, and seeking preventative care.

Still, it’s probably a good idea to lower your exposure to microplastics even if you can’t avoid them completely. Although you can cut back your exposure in as many ways as there are sources of plastic, the experts I spoke with recommended focusing on exposures from water, food, and air.

I talked to three doctors and a research scientist for tips on how to reduce the amount of tiny plastics and their chemicals that you (or your kids ) might ingest. Here’s what they recommend.

1. Cut back on bottled water

Some research indicates plastic bottled water may be a significant source of microplastics. While scientists are still studying just how significant, one study from 2019 of water and other commonly consumed food and drink found it to be the most concentrated source .

There is emerging evidence that on average, bottled water contains more microplastics than tap. (One study published in 2024 suggests that we have underestimated measured concentrations.)

Drinking bottled water in a pinch isn't the end of the world, but if you have concerns about it, you could always consider carrying a reusable steel or glass bottle or tumbler when out and about.

2. Get an NSF-certified water filter

Switching to tap water from plastic bottled water will likely significantly reduce your routine exposure to plastics. But while the average plastic water bottle contains more microplastics and nanoplastics than tap, research shows that tap water may also be a source of microplastics.

Several of our water filter picks are specifically NSF/American National Standards Institute–certified to reduce microplastics, which means they’ve been rigorously tested in an accredited lab. They’re certified only to reduce since the filters cannot guarantee total elimination. Our picks include under-sink filters , such as the Aquasana AQ-5200 , and the Brita Elite , a pitcher filter .

Aquasana AQ-5200

Exceptional, affordable under-sink filtration.

Certified for the most contaminants, widely available, affordable, and compact.

Buying Options

$100 + FS w/code AQWC50

Brita Elite Filter

Ace filtration, long lifespan.

This 10-cup, user-friendly model is rated to last six months between replacements.

Yes, it’s ironic that most NSF/ANSI-certified water filters contain plastic. But any microplastic shedding from using the plastic filter is likely to be minimal, as long as you avoid running hot water through the filter and store your water in the fridge, since heat accelerates plastic degradation.

Research suggests that boiling tap water, cooling it, and then filtering it may be especially effective at reducing microplastics, although it’s less practical for most people than simply using a filter.

3. Don’t use plastic to store food

Plastic food storage and packaging is so common that it’s difficult to avoid entirely. But your safest bet is to avoid storing food or liquid in plastic when possible and to minimize exposing any plastic (even those that say they’re BPA-free or microwave-safe) to high heat. Sunlight, acids, and physical erosion can also degrade plastic.

4. Don’t reuse single-use plastics for food and drinks

It’s great to reuse single-use plastic —just not for food. Unless you’re using the plastic in the freezer, save it for something that isn’t food storage or reheating, said Dr. Gillian Goddard, an endocrinologist and author at ParentData , a science-based online resource for parents. That means don’t reuse plastic takeout containers, breastmilk bags, or drink bottles.

5. Don’t microwave in plastic

Avoid microwaving or heating food or water in plastic—even if it says it’s microwave-safe, said Tracey Woodruff, director of the Program on Reproductive Health and the Environment at University of California San Francisco. Instead, consider glass or ceramic. The Pyrex Simply Store 18-Piece Set is our pick for the best food storage containers , and they survived our drop tests, stack neatly, and come with user-friendly lids (although you may not want to microwave the plastic lids). Our runner-up, the leakproof Glasslock 18-Piece Container Set , is another great option.

Pyrex Simply Store 18-Piece Set

The best glass container set.

The Pyrex Simply Store containers stack neatly and are made from durable tempered glass. The colorful lids make it easier to match their shape to the corresponding container, though you may need to replace them over time.

Glasslock 18-Piece Container Set

The best leakproof glass container set.

The Glasslock containers have locking lids that will prevent leaks. But these lids also put stress on the lips of the containers, so the glass may be prone to chipping over time.

6. Wash plastic by hand

Dishwasher temperatures run very hot and can degrade plastic—even dishwasher-safe plastic—and lead to microplastic shedding. Try to wash your plastic food containers by hand.

7. Use wood or bamboo cutting boards

Some research suggests that plastic cutting boards can be a significant source of microplastics in your diet, since repeated cutting on their surface can dislodge particles that adhere to food. Wood cutting boards also have some other advantages: They’re better for your knife blades and last longer than plastic when properly maintained.

Teakhaus Medium Professional Carving Board with Juice Canal 109

The best wood cutting board.

This beautiful teak board requires more careful cleaning than a plastic board, but it feels better under a knife and is easier to maintain than the other wood boards we tested.

Our cutting board pick, the Teakhaus Medium Professional Carving Board with Juice Canal 109 , is made from sustainably harvested teak. If you still prefer plastic for certain uses, use it sparingly and replace it after heavy scarring.

8. Clean your air

The air we breathe is also a potential source of microplastics, in the form of dust. Reducing airborne dust in your home, then, may reduce your exposure to inhaled microplastics.

SEBO Airbelt K3 Premium

The best canister vacuum.

This bagged canister vacuum excels on both bare floors and carpets, and has many adjustment options and useful attachments. It should last for the long haul.

7-Year Standard Warranty

10-Year Extended Warranty

That means doing boring stuff, like vacuuming regularly with a bagged, sealed-system vacuum that has a HEPA or S-class filter and mopping and wiping down surfaces with a damp sponge or cloth (since dusting kicks those tiny particles back up into the air).

Coway Airmega AP-1512HH Mighty

Exceptional, efficient, affordable.

Perfect for bedrooms, playrooms, and living rooms, this air purifier is one of the highest-performing, most-durable, and most-economical models we’ve tested.

You should also take care of seasonal chores like cleaning fans and AC unit filters and changing HVAC filters, and consider getting an air purifier if you live near a busy road.

Take special steps for infants and young children

Infants may be exposed to microplastics and nanoplastics in much higher concentrations than adults. Research shows that this exposure may be cause for concern, particularly at critical stages of early development. But much like health risks to adults, it’s important to think of microplastics exposure as just one piece of a child’s overall health.

“I emphasize that before putting much energy and resources into minimizing unknown risks, it is worth attending to reducing the risks we know about,” said Dr. Carlos Lerner, a pediatrician and professor of clinical pediatrics at UCLA Health. He cited following safe sleep recommendations for infants, avoiding secondhand smoke, and practicing good nutrition as examples.

If you want to take a more precautionary approach, avoid using plastic to warm formula or breastmilk. This is the main point of advice from the experts I spoke with, as well as the Cleveland Clinic .

1. Avoid microwaving or heating formula in plastic

Recent evidence shows that polypropylene-bottle-fed babies may swallow very high levels of tiny plastics due to the high temperatures used to sterilize bottles and prepare formula, as well as shaking the bottles to mix. If you want to feed your baby warmed formula and use plastic bottles, consider premixing the formula in a glass container, then cooling it down before transferring it to the feeding bottle.

2. Rinse heat-sterilized plastic bottles before adding formula or breastmilk

If you use heat to sterilize plastic bottles, leave them to cool then rinse them several times before filling them with formula or breastmilk, Lerner suggested.

3. Consider glass or silicone over plastic bottles

If your baby prefers warmed milk or formula, consider heating it in a glass or silicone bottle. (If you don't use a bottle warmer, we have advice about how to safely do this without one.) The Philips Avent Glass Natural Response Baby Bottle  is our recommendation for the best glass baby bottle.

Philips Avent Glass Natural Response Baby Bottle

Our favorite glass bottles.

With only three pieces and a large, easy-to-screw-on collar, this glass bottle is simple to use and didn’t leak in our test. But the very wide nipple may not work well for all babies.

4. Wash hands before eating

For young kids who eat with their hands, try to establish a habit of handwashing before eating, said Woodruff. While handwashing is not always possible, it can help reduce exposure from touching microplastics in dust and soil (and maybe, just maybe, stem the tide of germs).

How worried should you be about microplastics?

Scientists are still studying the exact connections between these teeny tiny pieces of plastic and human health. But it’s clear that exposure to plastic—whether it’s those tiny particles, the chemicals they leach, or a combination—is being linked to a variety of worrying health issues.

Some of those connections still require more research, such as ties to colon cancer , respiratory disease , metabolic function , and disruption to endocrine systems , while others—like a recent study that found those with levels of plastics in their arteries were at a higher risk for heart attacks, strokes, and death—seem a little more clear.

It’s important to remember that these links point to concerns about the impact of microplastics on public health, but they are not specific, predictable outcomes. “What I’m thinking about is population risk, not a risk to a specific individual,” said Goddard.

The tricky thing is that microplastics and nanoplastics are impossible to avoid, no matter how diligent you are: They’re in the air we breathe , our drinking water , and our food. But scientists aren’t sure what levels of microplastics and nanoplastics we’re each taking in from those sources.

The oft-cited estimate that the average person eats a credit card’s worth of plastic every week has been called into question . But our bodies are certainly taking in plastic, and that’s more than nature intended.

Given the growing body of evidence, it’s possible that we’ll start to see more public health measures that address microplastic pollution. Until then, taking care of your overall health is the first line of defense, followed by taking reasonable steps to reduce microplastic exposure.

COVID-19: Long-term effects

Some people continue to experience health problems long after having COVID-19. Understand the possible symptoms and risk factors for post-COVID-19 syndrome.

Most people who get coronavirus disease 2019 (COVID-19) recover within a few weeks. But some people — even those who had mild versions of the disease — might have symptoms that last a long time afterward. These ongoing health problems are sometimes called post- COVID-19 syndrome, post- COVID conditions, long COVID-19 , long-haul COVID-19 , and post acute sequelae of SARS COV-2 infection (PASC).

What is post-COVID-19 syndrome and how common is it?

Post- COVID-19 syndrome involves a variety of new, returning or ongoing symptoms that people experience more than four weeks after getting COVID-19 . In some people, post- COVID-19 syndrome lasts months or years or causes disability.

Research suggests that between one month and one year after having COVID-19 , 1 in 5 people ages 18 to 64 has at least one medical condition that might be due to COVID-19 . Among people age 65 and older, 1 in 4 has at least one medical condition that might be due to COVID-19 .

What are the symptoms of post-COVID-19 syndrome?

The most commonly reported symptoms of post- COVID-19 syndrome include:

• Symptoms that get worse after physical or mental effort
• Lung (respiratory) symptoms, including difficulty breathing or shortness of breath and cough

Other possible symptoms include:

• Neurological symptoms or mental health conditions, including difficulty thinking or concentrating, headache, sleep problems, dizziness when you stand, pins-and-needles feeling, loss of smell or taste, and depression or anxiety
• Joint or muscle pain
• Heart symptoms or conditions, including chest pain and fast or pounding heartbeat
• Digestive symptoms, including diarrhea and stomach pain
• Blood clots and blood vessel (vascular) issues, including a blood clot that travels to the lungs from deep veins in the legs and blocks blood flow to the lungs (pulmonary embolism)
• Other symptoms, such as a rash and changes in the menstrual cycle

Keep in mind that it can be hard to tell if you are having symptoms due to COVID-19 or another cause, such as a preexisting medical condition.

It's also not clear if post- COVID-19 syndrome is new and unique to COVID-19 . Some symptoms are similar to those caused by chronic fatigue syndrome and other chronic illnesses that develop after infections. Chronic fatigue syndrome involves extreme fatigue that worsens with physical or mental activity, but doesn't improve with rest.

Why does COVID-19 cause ongoing health problems?

Organ damage could play a role. People who had severe illness with COVID-19 might experience organ damage affecting the heart, kidneys, skin and brain. Inflammation and problems with the immune system can also happen. It isn't clear how long these effects might last. The effects also could lead to the development of new conditions, such as diabetes or a heart or nervous system condition.

The experience of having severe COVID-19 might be another factor. People with severe symptoms of COVID-19 often need to be treated in a hospital intensive care unit. This can result in extreme weakness and post-traumatic stress disorder, a mental health condition triggered by a terrifying event.

What are the risk factors for post-COVID-19 syndrome?

You might be more likely to have post- COVID-19 syndrome if:

• You had severe illness with COVID-19 , especially if you were hospitalized or needed intensive care.
• You had certain medical conditions before getting the COVID-19 virus.
• You had a condition affecting your organs and tissues (multisystem inflammatory syndrome) while sick with COVID-19 or afterward.

Post- COVID-19 syndrome also appears to be more common in adults than in children and teens. However, anyone who gets COVID-19 can have long-term effects, including people with no symptoms or mild illness with COVID-19 .

What should you do if you have post-COVID-19 syndrome symptoms?

If you're having symptoms of post- COVID-19 syndrome, talk to your health care provider. To prepare for your appointment, write down:

• When your symptoms started
• What makes your symptoms worse
• How often you experience symptoms
• How your symptoms affect your activities

Your health care provider might do lab tests, such as a complete blood count or liver function test. You might have other tests or procedures, such as chest X-rays, based on your symptoms. The information you provide and any test results will help your health care provider come up with a treatment plan.

In addition, you might benefit from connecting with others in a support group and sharing resources.

What Is Climate Change?

Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun’s activity or large volcanic eruptions. But since the 1800s, human activities have been the main driver of climate change , primarily due to the burning of fossil fuels like coal, oil and gas.

Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures.

The main greenhouse gases that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and cutting down forests can also release carbon dioxide. Agriculture, oil and gas operations are major sources of methane emissions. Energy, industry, transport, buildings, agriculture and land use are among the main sectors  causing greenhouse gases.

Humans are responsible for global warming

Climate scientists have showed that humans are responsible for virtually all global heating over the last 200 years. Human activities like the ones mentioned above are causing greenhouse gases that are warming the world faster than at any time in at least the last two thousand years.

The average temperature of the Earth’s surface is now about 1.2°C warmer than it was in the late 1800s (before the industrial revolution) and warmer than at any time in the last 100,000 years. The last decade (2011-2020) was the warmest on record , and each of the last four decades has been warmer than any previous decade since 1850.

Many people think climate change mainly means warmer temperatures. But temperature rise is only the beginning of the story. Because the Earth is a system, where everything is connected, changes in one area can influence changes in all others.

The consequences of climate change now include, among others, intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity.

People are experiencing climate change in diverse ways

Climate change can affect our health , ability to grow food, housing, safety and work. Some of us are already more vulnerable to climate impacts, such as people living in small island nations and other developing countries. Conditions like sea-level rise and saltwater intrusion have advanced to the point where whole communities have had to relocate, and protracted droughts are putting people at risk of famine. In the future, the number of people displaced by weather-related events is expected to rise.

Every increase in global warming matters

In a series of UN reports , thousands of scientists and government reviewers agreed that limiting global temperature rise to no more than 1.5°C would help us avoid the worst climate impacts and maintain a livable climate. Yet policies currently in place point to a 3°C temperature rise by the end of the century.

The emissions that cause climate change come from every part of the world and affect everyone, but some countries produce much more than others .The seven biggest emitters alone (China, the United States of America, India, the European Union, Indonesia, the Russian Federation, and Brazil) accounted for about half of all global greenhouse gas emissions in 2020.

Everyone must take climate action, but people and countries creating more of the problem have a greater responsibility to act first.

We face a huge challenge but already know many solutions

Many climate change solutions can deliver economic benefits while improving our lives and protecting the environment. We also have global frameworks and agreements to guide progress, such as the Sustainable Development Goals , the UN Framework Convention on Climate Change and the Paris Agreement . Three broad categories of action are: cutting emissions, adapting to climate impacts and financing required adjustments.

Switching energy systems from fossil fuels to renewables like solar or wind will reduce the emissions driving climate change. But we have to act now. While a growing number of countries is committing to net zero emissions by 2050, emissions must be cut in half by 2030 to keep warming below 1.5°C. Achieving this means huge declines in the use of coal, oil and gas: over two-thirds of today’s proven reserves of fossil fuels need to be kept in the ground by 2050 in order to prevent catastrophic levels of climate change.

Adapting to climate consequences protects people, homes, businesses, livelihoods, infrastructure and natural ecosystems. It covers current impacts and those likely in the future. Adaptation will be required everywhere, but must be prioritized now for the most vulnerable people with the fewest resources to cope with climate hazards. The rate of return can be high. Early warning systems for disasters, for instance, save lives and property, and can deliver benefits up to 10 times the initial cost.

We can pay the bill now, or pay dearly in the future

Climate action requires significant financial investments by governments and businesses. But climate inaction is vastly more expensive. One critical step is for industrialized countries to fulfil their commitment to provide $100 billion a year to developing countries so they can adapt and move towards greener economies.

Monitoring reports of the effectiveness of COVID-19 vaccination

Data on the real-world efficacy of the COVID-19 vaccines.

Applies to England

The UK Health Security Agency ( UKHSA ) is monitoring the effectiveness of the COVID-19 vaccines in the real world as set out in the COVID-19 vaccine surveillance strategy and has published reports on the impact of the COVID-19 vaccines on:

• symptomatic disease
• hospitalisation
• infection (symptomatic or asymptomatic)

Effectiveness of autumn 2023 COVID-19 vaccination and residual protection of prior doses against hospitalisation in England, estimated using a test-negative case-control study

This study estimates the long-term duration of protection of the COVID-19 vaccines against hospitalisation for all adults in England , depending on which vaccine individuals were last eligible to receive. This includes the effectiveness of the latest booster programme; XBB.1.5 monovalent boosters given to those aged 65 years and older as part of the autumn 2023 vaccination programme. The effectiveness of the recent XBB.1.5 vaccines against hospitalisation with the sub-lineages circulating during the study period (XBB-sub-lineages, EG.5.1 and JN.1) is also estimated.

Effectiveness of the Sanofi/GSK (VidPrevtyn Beta) and Pfizer-BioNTech (Comirnaty Original/Omicron BA.4-5) bivalent vaccines against hospitalisation in England

This study estimates vaccine effectiveness against hospitalisation of the Sanofi/GSK booster (based on the Beta variant) and the Pfizer Original/BA.4-5 bivalent booster (based on the ancestral and BA.4/5 Omicron sub-lineages), given as part of the spring 2023 vaccination programme, amongst those aged 75 years and older in England.

Duration of protection of ancestral-strain monovalent vaccines and effectiveness of bivalent BA.1 boosters against COVID-19 hospitalisation in England: a test-negative case-control study

This study estimates the long-term duration of protection of the monovalent COVID-19 vaccines against hospitalisation, as well as the incremental vaccine effectiveness against hospitalisation of the bivalent BA.1 booster vaccines given as part of the autumn 2022 booster campaign to those aged 50 years or older.

Effectiveness of the COVID-19 vaccines against severe disease with Omicron sub-lineages BA.4 and BA.5 in England

The latest evidence shows that vaccine effectiveness against hospitalisation is similar for the BA.4/5 variants as it is for BA.2. ​In somebody who received their second dose around 6 months previously, a booster dose increases protection against hospitalisation by 50% to 60%. This is the most comprehensive analysis of vaccine effectiveness against hospitalisation for BA.4/5 undertaken to date.

Effectiveness of AstraZeneca COVID-19 booster vaccination against the Omicron and Delta variants

This study estimates the effectiveness of booster vaccination with AstraZeneca against symptomatic disease and hospitalisation in individuals who were not able to receive mRNA vaccines in the UK.

Effectiveness of the COVID-19 vaccines against the Omicron BA.2 sub-lineage

This study estimates the effectiveness of booster vaccination against symptomatic disease caused by the BA.2 sub-lineage of the Omicron (B.1.1.529) variant.

Effectiveness of COVID-19 vaccines against Omicron and Delta hospitalisation

This study estimates vaccine effectiveness against hospitalisation with the Omicron and Delta variants and investigates the impact of using different hospitalisation outcome definitions.

Effectiveness of COVID-19 vaccines against hospitalisation with the Omicron variant in adults aged 75 years and older

This study reports on vaccine effectiveness against hospitalisation with the Omicron variant in adults aged 75 years and older.

Effectiveness of COVID-19 vaccines against transmission

This study reports on vaccine effectiveness against transmission of COVID-19 with the Alpha and Delta variants.

Effectiveness of 3 doses of COVID-19 vaccines against symptomatic COVID-19 and hospitalisation in adults aged 65 years and older

Updated analysis on the effectiveness of 3 doses of COVID-19 vaccines against symptomatic COVID-19 and hospitalisation in adults aged 65 years and older.

Effectiveness of BNT162b2 (Comirnaty, Pfizer-BioNTech) COVID-19 booster vaccine against COVID-19 related symptoms and hospitalisation in England: test negative case-control study

This study provides real world evidence of significant increased protection from the booster vaccine dose against symptomatic disease and hospitalisation irrespective of the primary course.

Effectiveness of COVID-19 vaccines against the Omicron (B.1.1.529) variant of concern

This study reports on the vaccine effectiveness against symptomatic disease with 2 dose courses of BNT1622 and ChAdOx1-S as well as booster doses of BNT162b2 following a primary course of either BNT1622 or ChAdOx1-S.

Effectiveness of BNT162b2 (Comirnaty, Pfizer-BioNTech) COVID-19 booster vaccine against COVID-19 related symptoms in England: test negative case-control study

Results from the first UK real-world study by UKHSA show significantly increased protection against symptomatic disease from a booster dose of the Pfizer-BioNTech vaccine in those aged 50 years and older.

Vaccine effectiveness and duration of protection

This study reports on the vaccine effectiveness and duration of protection of Comirnaty, Vaxzevria and Spikevax against mild and severe COVID-19 in the UK.

Different dosing schedules and vaccine effectiveness

This study investigates the impact of different dosing schedules on immune response and vaccine effectiveness.

Vaccine effectiveness in clinical risk groups

This study reports on the immune response and clinical effectiveness of COVID-19 vaccine among individuals in clinical risk groups.

Vaccine effectiveness with Delta variant on hospitalisation

This study reports on the effectiveness of COVID-19 vaccines on hospitalisation disease with the Delta variant . A supplementary appendix is also available to download.

Vaccine effectiveness with Delta variant on symptomatic disease

This study reports on the effectiveness of COVID-19 vaccines on symptomatic disease with the Delta variant.

Effectiveness of COVID-19 vaccines against hospitalisation

A study using the SARI watch surveillance system of COVID-19 hospitalisations found high levels of protection against hospitalisation after both a single dose and 2 doses of COVID-19 vaccines.

Effectiveness of COVID-19 vaccines on mortality

A study on deaths with COVID-19 indicates that COVID-19 vaccines offer high levels of protection against mortality .

Impact on household transmission

Impact of vaccination on household transmission of SARS-CoV-2 in England is an analysis to determine whether individuals who have received vaccine, but still become infected with SARS-CoV-2 up to 60 days after the first dose, are less likely than unvaccinated cases to transmit to their unvaccinated household contacts.

VIVALDI study

The VIVALDI study found evidence that COVID-19 vaccines were associated with a substantially reduced risk of infection in care home residents.

Avon CAP study

The Avon CAP study , conducted in 2 hospitals in Bristol, found evidence of high levels of protection against hospitalisation in 80+ year olds with a single dose of either vaccine.

SIREN study

Early data from the SIREN study shows a promising impact on infection in healthcare workers aged under 65. Healthcare workers in the study are tested for COVID-19 every 2 weeks – whether or not they have symptoms.
