Table of Contents
The discussion section in scientific manuscripts might be the last few paragraphs, but its role goes far beyond wrapping up. It’s the part of an article where scientists talk about what they found and what it means, where raw data turns into meaningful insights. Therefore, discussion is a vital component of the article.
An excellent discussion is well-organized. We bring to you authors a classic 6-step method for writing discussion sections, with examples to illustrate the functions and specific writing logic of each step. Take a look at how you can impress journal reviewers with a concise and focused discussion section!
Discussion frame structure
Conventionally, a discussion section has three parts: an introductory paragraph, a few intermediate paragraphs, and a conclusion¹. Please follow the steps below:
1.Introduction—mention gaps in previous research¹⁻ ²
Here, you orient the reader to your study. In the first paragraph, it is advisable to mention the research gap your paper addresses.
Example: This study investigated the cognitive effects of a meat-only diet on adults. While earlier studies have explored the impact of a carnivorous diet on physical attributes and agility, they have not explicitly addressed its influence on cognitively intense tasks involving memory and reasoning.
2. Summarizing key findings—let your data speak ¹⁻ ²
After you have laid out the context for your study, recapitulate some of its key findings. Also, highlight key data and evidence supporting these findings.
Example: We found that risk-taking behavior among teenagers correlates with their tendency to invest in cryptocurrencies. Risk takers in this study, as measured by the Cambridge Gambling Task, tended to have an inordinately higher proportion of their savings invested as crypto coins.
3. Interpreting results—compare with other papers¹⁻²
Here, you must analyze and interpret any results concerning the research question or hypothesis. How do the key findings of your study help verify or disprove the hypothesis? What practical relevance does your discovery have?
Example: Our study suggests that higher daily caffeine intake is not associated with poor performance in major sporting events. Athletes may benefit from the cardiovascular benefits of daily caffeine intake without adversely impacting performance.
Remember, unlike the results section, the discussion ideally focuses on locating your findings in the larger body of existing research. Hence, compare your results with those of other peer-reviewed papers.
Example: Although Miller et al. (2020) found evidence of such political bias in a multicultural population, our findings suggest that the bias is weak or virtually non-existent among politically active citizens.
4. Addressing limitations—their potential impact on the results¹⁻²
Discuss the potential impact of limitations on the results. Most studies have limitations, and it is crucial to acknowledge them in the intermediary paragraphs of the discussion section. Limitations may include low sample size, suspected interference or noise in data, low effect size, etc.
Example: This study explored a comprehensive list of adverse effects associated with the novel drug ‘X’. However, long-term studies may be needed to confirm its safety, especially regarding major cardiac events.
5. Implications for future research—how to explore further¹⁻²
Locate areas of your research where more investigation is needed. Concluding paragraphs of the discussion can explain what research will likely confirm your results or identify knowledge gaps your study left unaddressed.
Example: Our study demonstrates that roads paved with the plastic-infused compound ‘Y’ are more resilient than asphalt. Future studies may explore economically feasible ways of producing compound Y in bulk.
6. Conclusion—summarize content¹⁻²
A good way to wind up the discussion section is by revisiting the research question mentioned in your introduction. Sign off by expressing the main findings of your study.
Example: Recent observations suggest that the fish ‘Z’ is moving upriver in many parts of the Amazon basin. Our findings provide conclusive evidence that this phenomenon is associated with rising sea levels and climate change, not due to elevated numbers of invasive predators.
A rigorous and concise discussion section is one of the keys to achieving an excellent paper. It serves as a critical platform for researchers to interpret and connect their findings with the broader scientific context. By detailing the results, carefully comparing them with existing research, and explaining the limitations of this study, you can effectively help reviewers and readers understand the entire research article more comprehensively and deeply¹⁻² , thereby helping your manuscript to be successfully published and gain wider dissemination.

Start Strong with a Summary of Key Findings
Kick off your discussion section with a concise summary of your essential findings. This isn't just a recap; it's about highlighting the central results that tie your study together. You've already detailed these findings in the results section, so focus on the big picture. Avoid rehashing every point, but do provide a few key highlights. This will refresh your reader’s memory and keep them engaged with the core message of your paper.
Write Clearly and Concisely
Clarity is crucial here. While your results section might have been packed with technical jargon, the discussion is where you explain what it all means in plain language. This is where you’ll make some of your paper’s most impactful points, so ensure your writing is straightforward.
Interpret What Your Results Mean
Once you've laid out your findings, it's time to interpret them. What do your results mean in the context of your research question? Dive into the implications and significance of your findings . If your introduction mentioned theories or studies that could illuminate your results, now’s the time to use them.
Tackle Unexpected or Contradictory Results

2. Recap Key Findings Briefly
Start your discussion with a quick overview of the main findings. Keep it brief—no need to repeat everything from the results section. Focus on critical numbers, especially if you compare them to literature values next. This part acts as a bridge to your critical analysis of the results. Use phrases like “The results XXX and YYY indicate that [critical analysis]…” or “Because of XXX, we can say that [interpretation]…” Avoid introducing new results here.
3. Analyze Your Results Critically
Move beyond describing results to explain what they mean and what you’ve learned. Focus on unexpected, significant, or unusual findings. Highlight new trends, relationships, and knowledge uncovered by your research. List your analyses in the order in which the results section is based. If there are alternative explanations for your results, mention them and explain why you’ve excluded them.
4. Connect to Existing Research
Now, compare your findings to previous studies, especially those that inspired your work or raised questions you’ve addressed. Place your work within the larger context and show how it integrates. Use papers from the field to support any claims or speculations. If your conclusions contradict other studies, discuss plausible explanations for the discrepancy. Also, mention any generalizations you can now make about the field.
5. Address the Research Gap
Explain how your work addresses a gap in the field, showing its importance. This gap, whether large or small, should have been described in the introduction. Briefly reiterate it here, highlighting how your work fills this gap. Mention any lessons learned that advance the current edge of knowledge, such as recommending changes to best practices or known pathways.
6. Speculate on Broader Implications
Consider how your findings apply beyond current knowledge. This could include new insights, hypotheses for future testing, or research questions. Speculate how your results fit into a bigger picture or relate to the field more generally. Ensure your research and the broader field logically support these claims. Avoid making unsupported claims.
7. Outline Future Directions
Discuss how to move forward from your research . Mention any unanswered questions and possible routes for addressing them, but avoid discussing future directions that should have been included in your study. Propose future studies to test new hypotheses or address limitations. Highlight potential applications of your work, but stay realistic.

Kicking Off Your Discussion: Summarize Your Findings
Start your discussion by refreshing your readers' memories about your research's main goals and discoveries. Recap the core research question, briefly outline your methods, and summarize your results. Here's an example to illustrate:
“We aimed to compare the effectiveness and user-friendliness of different storm detection software for storm tracking. Based on these aims, we ran multiple experiments under the same conditions using different storm detection software. Our results showed that in both speed and accuracy of data, 'software A' performed better than 'software B.'"
Making Sense of Your Results: Interpret What You Found
Once you've set the stage, break down what your findings mean. Discuss the implications and significance in simple terms. Check out this example:
“The results of this study indicate significant differences between classical music and pop music in terms of their effects on memory recall and cognition. This suggests that as the complexity of the music increases, so does its ability to facilitate cognitive processing. This finding aligns with the well-known 'Mozart effect,' which proposes that listening to classical music can enhance cognitive function."
Connecting the Dots: Compare Your Results to Existing Literature
Now, it’s time to link your findings to previous research. Discuss how your results stack up against similar studies and what that means for your research's place in the broader field. Here's a good example:
“Our analysis predicts that climate change will have a significant impact on wheat yield. This finding contradicts one of the main pieces of evidence in some prior simulation studies [1-3] that suggest a negative effect of climate change on wheat yield, but the result is entirely consistent with the predictions of other research [4-5] that suggests the overall change in climate could result in increases in wheat yield.”

- How to Write Discussions and Conclusions
The discussion section contains the results and outcomes of a study. An effective discussion informs readers what can be learned from your experiment and provides context for the results.
What makes an effective discussion?
When you’re ready to write your discussion, you’ve already introduced the purpose of your study and provided an in-depth description of the methodology. The discussion informs readers about the larger implications of your study based on the results. Highlighting these implications while not overstating the findings can be challenging, especially when you’re submitting to a journal that selects articles based on novelty or potential impact. Regardless of what journal you are submitting to, the discussion section always serves the same purpose: concluding what your study results actually mean.
A successful discussion section puts your findings in context. It should include:
- the results of your research,
- a discussion of related research, and
- a comparison between your results and initial hypothesis.
Tip: Not all journals share the same naming conventions.
You can apply the advice in this article to the conclusion, results or discussion sections of your manuscript.
Our Early Career Researcher community tells us that the conclusion is often considered the most difficult aspect of a manuscript to write. To help, this guide provides questions to ask yourself, a basic structure to model your discussion off of and examples from published manuscripts.
Questions to ask yourself:
- Was my hypothesis correct?
- If my hypothesis is partially correct or entirely different, what can be learned from the results?
- How do the conclusions reshape or add onto the existing knowledge in the field? What does previous research say about the topic?
- Why are the results important or relevant to your audience? Do they add further evidence to a scientific consensus or disprove prior studies?
- How can future research build on these observations? What are the key experiments that must be done?
- What is the “take-home” message you want your reader to leave with?
How to structure a discussion
Trying to fit a complete discussion into a single paragraph can add unnecessary stress to the writing process. If possible, you’ll want to give yourself two or three paragraphs to give the reader a comprehensive understanding of your study as a whole. Here’s one way to structure an effective discussion:
Writing Tips
While the above sections can help you brainstorm and structure your discussion, there are many common mistakes that writers revert to when having difficulties with their paper. Writing a discussion can be a delicate balance between summarizing your results, providing proper context for your research and avoiding introducing new information. Remember that your paper should be both confident and honest about the results!
- Read the journal’s guidelines on the discussion and conclusion sections. If possible, learn about the guidelines before writing the discussion to ensure you’re writing to meet their expectations.
- Begin with a clear statement of the principal findings. This will reinforce the main take-away for the reader and set up the rest of the discussion.
- Explain why the outcomes of your study are important to the reader. Discuss the implications of your findings realistically based on previous literature, highlighting both the strengths and limitations of the research.
- State whether the results prove or disprove your hypothesis. If your hypothesis was disproved, what might be the reasons?
- Introduce new or expanded ways to think about the research question. Indicate what next steps can be taken to further pursue any unresolved questions.
- If dealing with a contemporary or ongoing problem, such as climate change, discuss possible consequences if the problem is avoided.
- Be concise. Adding unnecessary detail can distract from the main findings.
Don’t
- Rewrite your abstract. Statements with “we investigated” or “we studied” generally do not belong in the discussion.
- Include new arguments or evidence not previously discussed. Necessary information and evidence should be introduced in the main body of the paper.
- Apologize. Even if your research contains significant limitations, don’t undermine your authority by including statements that doubt your methodology or execution.
- Shy away from speaking on limitations or negative results. Including limitations and negative results will give readers a complete understanding of the presented research. Potential limitations include sources of potential bias, threats to internal or external validity, barriers to implementing an intervention and other issues inherent to the study design.
- Overstate the importance of your findings. Making grand statements about how a study will fully resolve large questions can lead readers to doubt the success of the research.

Discussion Section Examples and Writing Tips
Abstract | Introduction | Literature Review | Research question | Materials & Methods | Results | Discussion | Conclusion
In this blog, we look at how to write the discussion section of a research paper. We will go through plenty of discussion examples and understand how to construct a great discussion section for your research paper.
1. What is the purpose of the discussion section?
The discussion section is one of the most important sections of your research paper. This is where you interpret your results, highlight your contributions, and explain the value of your work to your readers. This is one of the challenging parts to write because the author must clearly explain the significance of their results and tie everything back to the research questions.
2. How should I structure my discussion section?
Generally, the discussion section of a research paper typically contains the following parts.
Research summary It is a good idea to start this section with an overall summary of your work and highlight the main findings of your research.
Interpretation of findings You must interpret your findings clearly to your readers one by one.
Comparison with literature You must talk about how your results fit into existing research in the literature.
Implications of your work You should talk about the implications and possible benefits of your research.
Limitations You should talk about the possible limitations and shortcomings of your research
Future work And finally, you can talk about the possible future directions of your work.
3. Discussion Examples
Let’s look at some examples of the discussion section. We will be looking at discussion examples from different fields and of different formats. We have split this section into multiple components so that it is easy for you to digest and understand.
3.1. An example of research summary in discussion
It is a good idea to start your discussion section with the summary of your work. The best way to do this will be to restate your research question, and then reminding your readers about your methods, and finally providing an overall summary of your results.
Our aims were to compare the effectiveness and user-friendliness of different storm detection software for storm tracking. On the basis of these aims, we ran multiple experiments with the same conditions using different storm detection software. Our results showed that in both speed and accuracy of data, ‘software A’ performed better than ‘software B’. _ Aims summary _ Methodology summary _ Results summary
This discussion example is from an engineering research paper. The authors are restating their aims first, which is to compare different types of storm-tracking software. Then, they are providing a brief summary of the methods. Here, they are testing different storm-tracking software under different conditions to see which performs the best. Then, they are finally providing their main finding which is that they found ‘software A’ better than ‘software B’. This is a very good example of how to start the discussion section by presenting a summary of your work.
3.2. An example of result interpretation in discussion
The next step is to interpret your results. You have to explain your results clearly to your readers. Here is a discussion example that shows how to interpret your results.
The results of this study indicate significant differences between classical music and pop music in terms of their effects on memory recall and cognition. This implies that as the complexity of the music increases, so does its ability to facilitate cognitive processing. This finding aligns with the well-known “Mozart effect,” which suggests that listening to classical music can enhance cognitive function. _ Result _ Interpretation _ Additional evidence
The authors are saying that their results show that there is a significant difference between pop music and classical music in terms of memory recall and cognition. Now they are providing their interpretation of the findings. They think it is because there is a link between the complexity of music and cognitive processing. They are also making a reference to a well-known theory called the ‘Mozart effect’ to back up their findings. It is a nicely written passage and the author’s interpretation sounds very convincing and credible.
3.3. An example of literature comparison in discussion
The next step is to compare your results to the literature. You have to explain clearly how your findings compare with similar findings made by other researchers. Here is a discussion example where authors are providing details of papers in the literature that both support and oppose their findings.
Our analysis predicts that climate change will have a significant impact on wheat yield. This finding undermines one of the central pieces of evidence in some previous simulation studies [1-3] that suggest a negative effect of climate change on wheat yield, but the result is entirely consistent with the predictions of other research [4-5] that suggests the overall change in climate could result in increases in wheat yield. _ Result _ Comparison with literature
The authors are saying that their results show that climate change will have a significant effect on wheat production. Then, they are saying that there are some papers in the literature that are in agreement with their findings. However, there are also many papers in the literature that disagree with their findings. This is very important. Your discussion should be two-sided, not one-sided. You should not ignore the literature that doesn’t corroborate your findings.
3.4. An example of research implications in discussion
The next step is to explain to your readers how your findings will benefit society and the research community. You have to clearly explain the value of your work to your readers. Here is a discussion example where authors explain the implications of their research.
The results contribute insights with regard to the management of wildfire events using artificial intelligence. One could easily argue that the obvious practical implication of this study is that it proposes utilizing cloud-based machine vision to detect wildfires in real-time, even before the first responders receive emergency calls. _ Your finding _ Implications of your finding
In this paper, the authors are saying that their findings indicate that Artificial intelligence can be used to effectively manage wildfire events. Then, they are talking about the practical implications of their study. They are saying that their work has proven that machine learning can be used to detect wildfires in real-time. This is a great practical application and can save thousands of lives. As you can see, after reading this passage, you can immediately understand the value and significance of the work.
3.5. An example of limitations in discussion
It is very important that you discuss the limitations of your study. Limitations are flaws and shortcomings of your study. You have to tell your readers how your limitations might influence the outcomes and conclusions of your research. Most studies will have some form of limitation. So be honest and don’t hide your limitations. In reality, your readers and reviewers will be impressed with your paper if you are upfront about your limitations.
Study design and small sample size are important limitations. This could have led to an overestimation of the effect. Future research should reconfirm these findings by conducting larger-scale studies. _ Limitation _ How it might affect the results? _ How to fix the limitation?
Here is a discussion example where the author talks about study limitations. The authors are saying that the main limitations of the study are the small sample size and weak study design. Then they explain how this might have affected their results. They are saying that it is possible that they are overestimating the actual effect they are measuring. Then finally they are telling the readers that more studies with larger sample sizes should be conducted to reconfirm the findings.
As you can see, the authors are clearly explaining three things here:
3.6. An example of future work in discussion
It is important to remember not to end your paper with limitations. Finish your paper on a positive note by telling your readers about the benefits of your research and possible future directions. Here is a discussion example where the author talks about future work.
Our study highlights useful insights about the potential of biomass as a renewable energy source. Future research can extend this research in several ways, including research on how to tackle challenges that hinder the sustainability of renewable energy sources towards climate change mitigation, such as market failures, lack of information and access to raw materials. _ Benefits of your work _ Future work
The authors are starting the final paragraph of the discussion section by highlighting the benefit of their work which is the use of biomass as a renewable source of energy. Then they talk about future research. They are saying that future research can focus on how to improve the sustainability of biomass production. This is a very good example of how to finish the discussion section of your paper on a positive note.
4. Frequently Asked Questions
Sometimes you will have negative or unexpected results in your paper. You have to talk about it in your discussion section. A lot of students find it difficult to write this part. The best way to handle this situation is not to look at results as either positive or negative. A result is a result, and you will always have something important and interesting to say about your findings. Just spend some time investigating what might have caused this result and tell your readers about it.
You must talk about the limitations of your work in the discussion section of the paper. One of the important qualities that the scientific community expects from a researcher is honesty and admitting when they have made a mistake. The important trick you have to learn while presenting your limitations is to present them in a constructive way rather than being too negative about them. You must try to use positive language even when you are talking about major limitations of your work.
If you have something exciting to say about your results or found something new that nobody else has found before, then, don’t be modest and use flat language when presenting this in the discussion. Use words like ‘break through’, ‘indisputable evidence’, ‘exciting proposition’ to increase the impact of your findings.
Important thing to remember is not to overstate your findings. If you found something really interesting but are not 100% sure, you must not mislead your readers. The best way to do this will be to use words like ‘it appears’ and ‘it seems’. This will tell the readers that there is a slight possibility that you might be wrong.

How to Write the Discussion Section of a Research Paper
The discussion section of a research paper analyzes and interprets the findings, provides context, compares them with previous studies, identifies limitations, and suggests future research directions.
Updated on September 15, 2023
Structure your discussion section right, and you’ll be cited more often while doing a greater service to the scientific community. So, what actually goes into the discussion section? And how do you write it?
The discussion section of your research paper is where you let the reader know how your study is positioned in the literature, what to take away from your paper, and how your work helps them. It can also include your conclusions and suggestions for future studies.
First, we’ll define all the parts of your discussion paper, and then look into how to write a strong, effective discussion section for your paper or manuscript.
Discussion section: what is it, what it does
The discussion section comes later in your paper, following the introduction, methods, and results. The discussion sets up your study’s conclusions. Its main goals are to present, interpret, and provide a context for your results.
What is it?
The discussion section provides an analysis and interpretation of the findings, compares them with previous studies, identifies limitations, and suggests future directions for research.
This section combines information from the preceding parts of your paper into a coherent story. By this point, the reader already knows why you did your study (introduction), how you did it (methods), and what happened (results). In the discussion, you’ll help the reader connect the ideas from these sections.
Why is it necessary?
The discussion provides context and interpretations for the results. It also answers the questions posed in the introduction. While the results section describes your findings, the discussion explains what they say. This is also where you can describe the impact or implications of your research.
Adds context for your results
Most research studies aim to answer a question, replicate a finding, or address limitations in the literature. These goals are first described in the introduction. However, in the discussion section, the author can refer back to them to explain how the study's objective was achieved.
Shows what your results actually mean and real-world implications
The discussion can also describe the effect of your findings on research or practice. How are your results significant for readers, other researchers, or policymakers?
What to include in your discussion (in the correct order)
A complete and effective discussion section should at least touch on the points described below.
Summary of key findings
The discussion should begin with a brief factual summary of the results. Concisely overview the main results you obtained.
Begin with key findings with supporting evidence
Your results section described a list of findings, but what message do they send when you look at them all together?
Your findings were detailed in the results section, so there’s no need to repeat them here, but do provide at least a few highlights. This will help refresh the reader’s memory and help them focus on the big picture.
Read the first paragraph of the discussion section in this article (PDF) for an example of how to start this part of your paper. Notice how the authors break down their results and follow each description sentence with an explanation of why each finding is relevant.
State clearly and concisely
Following a clear and direct writing style is especially important in the discussion section. After all, this is where you will make some of the most impactful points in your paper. While the results section often contains technical vocabulary, such as statistical terms, the discussion section lets you describe your findings more clearly.
Interpretation of results
Once you’ve given your reader an overview of your results, you need to interpret those results. In other words, what do your results mean? Discuss the findings’ implications and significance in relation to your research question or hypothesis.
Analyze and interpret your findings
Look into your findings and explore what’s behind them or what may have caused them. If your introduction cited theories or studies that could explain your findings, use these sources as a basis to discuss your results.
For example, look at the second paragraph in the discussion section of this article on waggling honey bees. Here, the authors explore their results based on information from the literature.
Unexpected or contradictory results
Sometimes, your findings are not what you expect. Here’s where you describe this and try to find a reason for it. Could it be because of the method you used? Does it have something to do with the variables analyzed? Comparing your methods with those of other similar studies can help with this task.
Context and comparison with previous work
Refer to related studies to place your research in a larger context and the literature. Compare and contrast your findings with existing literature, highlighting similarities, differences, and/or contradictions.
How your work compares or contrasts with previous work
Studies with similar findings to yours can be cited to show the strength of your findings. Information from these studies can also be used to help explain your results. Differences between your findings and others in the literature can also be discussed here.
How to divide this section into subsections
If you have more than one objective in your study or many key findings, you can dedicate a separate section to each of these. Here’s an example of this approach. You can see that the discussion section is divided into topics and even has a separate heading for each of them.
Limitations
Many journals require you to include the limitations of your study in the discussion. Even if they don’t, there are good reasons to mention these in your paper.
Why limitations don’t have a negative connotation
A study’s limitations are points to be improved upon in future research. While some of these may be flaws in your method, many may be due to factors you couldn’t predict.
Examples include time constraints or small sample sizes. Pointing this out will help future researchers avoid or address these issues. This part of the discussion can also include any attempts you have made to reduce the impact of these limitations, as in this study .
How limitations add to a researcher's credibility
Pointing out the limitations of your study demonstrates transparency. It also shows that you know your methods well and can conduct a critical assessment of them.
Implications and significance
The final paragraph of the discussion section should contain the take-home messages for your study. It can also cite the “strong points” of your study, to contrast with the limitations section.
Restate your hypothesis
Remind the reader what your hypothesis was before you conducted the study.
How was it proven or disproven?
Identify your main findings and describe how they relate to your hypothesis.
How your results contribute to the literature
Were you able to answer your research question? Or address a gap in the literature?
Future implications of your research
Describe the impact that your results may have on the topic of study. Your results may show, for instance, that there are still limitations in the literature for future studies to address. There may be a need for studies that extend your findings in a specific way. You also may need additional research to corroborate your findings.
Sample discussion section
This fictitious example covers all the aspects discussed above. Your actual discussion section will probably be much longer, but you can read this to get an idea of everything your discussion should cover.
Our results showed that the presence of cats in a household is associated with higher levels of perceived happiness by its human occupants. These findings support our hypothesis and demonstrate the association between pet ownership and well-being.
The present findings align with those of Bao and Schreer (2016) and Hardie et al. (2023), who observed greater life satisfaction in pet owners relative to non-owners. Although the present study did not directly evaluate life satisfaction, this factor may explain the association between happiness and cat ownership observed in our sample.
Our findings must be interpreted in light of some limitations, such as the focus on cat ownership only rather than pets as a whole. This may limit the generalizability of our results.
Nevertheless, this study had several strengths. These include its strict exclusion criteria and use of a standardized assessment instrument to investigate the relationships between pets and owners. These attributes bolster the accuracy of our results and reduce the influence of confounding factors, increasing the strength of our conclusions. Future studies may examine the factors that mediate the association between pet ownership and happiness to better comprehend this phenomenon.
This brief discussion begins with a quick summary of the results and hypothesis. The next paragraph cites previous research and compares its findings to those of this study. Information from previous studies is also used to help interpret the findings. After discussing the results of the study, some limitations are pointed out. The paper also explains why these limitations may influence the interpretation of results. Then, final conclusions are drawn based on the study, and directions for future research are suggested.
How to make your discussion flow naturally
If you find writing in scientific English challenging, the discussion and conclusions are often the hardest parts of the paper to write. That’s because you’re not just listing up studies, methods, and outcomes. You’re actually expressing your thoughts and interpretations in words.
- How formal should it be?
- What words should you use, or not use?
- How do you meet strict word limits, or make it longer and more informative?
Always give it your best, but sometimes a helping hand can, well, help. Getting a professional edit can help clarify your work’s importance while improving the English used to explain it. When readers know the value of your work, they’ll cite it. We’ll assign your study to an expert editor knowledgeable in your area of research. Their work will clarify your discussion, helping it to tell your story. Find out more about AJE Editing.

The purpose of the discussion section is to interpret and describe the significance of your findings in relation to what was already known about the research problem being investigated and to explain any new understanding or insights that emerged as a result of your research. The discussion will always connect to the introduction by way of the research questions or hypotheses you posed and the literature you reviewed, but the discussion does not simply repeat or rearrange the first parts of your paper; the discussion clearly explains how your study advanced the reader's understanding of the research problem from where you left them at the end of your review of prior research. The discussion section is the most prominent place where your voice will emerge and where readers will most closely connect with you as a researcher.

Importance of a Good Discussion
The discussion section is often considered the most important part of your research paper because it:
- Most effectively demonstrates your ability as a researcher to think critically about an issue, to develop creative solutions to problems based upon a logical synthesis of the findings, and to formulate a deeper, more profound understanding of the research problem under investigation;
- Presents the underlying meaning of your research, notes possible implications in other areas of study, and explores possible improvements that can be made in order to further develop the concerns of your research;
- Highlights the importance of your study and how it can contribute to understanding the research problem within the field of study;
- Presents how the findings from your study revealed and helped fill gaps in the literature that had not been previously exposed or adequately described; and,
- Engages the reader in thinking critically about issues based on an evidence-based interpretation of findings; it is not governed strictly by objective reporting of information.

Structure and Writing Style
I. General Rules
These are the general rules you should adopt when composing your discussion of the results :
- Do not be verbose or repetitive; be concise and make your points clearly
- Avoid the use of jargon or undefined technical language
- Follow a logical stream of thought; in general, interpret and discuss the significance of your findings in the same sequence you described them in your results section [a notable exception is to begin by highlighting an unexpected result or a finding that can grab the reader's attention]
- Use the present verb tense, especially for established facts; however, refer to specific works or prior studies in the past tense
- If needed, use subheadings to help organize your discussion or to categorize your interpretations into themes
II. The Content
The content of the discussion section of your paper most often includes :
- Explanation of results : Comment on whether or not the results were expected for each set of findings; go into greater depth to explain findings that were unexpected or especially profound. If appropriate, note any unusual or unanticipated patterns or trends that emerged from your results and explain their meaning in relation to the research problem.
- References to previous research : Either compare your results with the findings from other studies or use the studies to support a claim. This can include re-visiting key sources already cited in your literature review section, or, save them to cite later in the discussion section if they are more important to compare with your results instead of being a part of the general literature review of prior research used to provide context and background information. Note that you can make this decision to highlight specific studies after you have begun writing the discussion section.
- Deduction : A claim for how the results can be applied more generally. For example, describing lessons learned, proposing recommendations that can help improve a situation, or highlighting best practices.
- Hypothesis : A more general claim or possible conclusion arising from the results [which may be proved or disproved in subsequent research]. This can be framed as new research questions that emerged as a consequence of your analysis.
III. Organization and Structure
Keep the following sequential points in mind as you organize and write the discussion section of your paper:
- Think of your discussion as an inverted pyramid. Organize the discussion from the general to the specific, linking your findings to the literature, then to theory, then to practice [if appropriate].
- Use the same key terms, narrative style, and verb tense [present] that you used when describing the research problem in your introduction.
- Begin by briefly re-stating the research problem you were investigating and answer all of the research questions underpinning the problem that you posed in the introduction.
- Describe the patterns, principles, and relationships shown by each major findings and place them in proper perspective. The sequence of this information is important; first state the answer, then the relevant results, then cite the work of others. If appropriate, refer the reader to a figure or table to help enhance the interpretation of the data [either within the text or as an appendix].
- Regardless of where it's mentioned, a good discussion section includes analysis of any unexpected findings. This part of the discussion should begin with a description of the unanticipated finding, followed by a brief interpretation as to why you believe it appeared and, if necessary, its possible significance in relation to the overall study. If more than one unexpected finding emerged during the study, describe each of them in the order they appeared as you gathered or analyzed the data. As noted, the exception to discussing findings in the same order you described them in the results section would be to begin by highlighting the implications of a particularly unexpected or significant finding that emerged from the study, followed by a discussion of the remaining findings.
- Before concluding the discussion, identify potential limitations and weaknesses if you do not plan to do so in the conclusion of the paper. Comment on their relative importance in relation to your overall interpretation of the results and, if necessary, note how they may affect the validity of your findings. Avoid using an apologetic tone; however, be honest and self-critical [e.g., in retrospect, had you included a particular question in a survey instrument, additional data could have been revealed].
- The discussion section should end with a concise summary of the principal implications of the findings regardless of their significance. Give a brief explanation about why you believe the findings and conclusions of your study are important and how they support broader knowledge or understanding of the research problem. This can be followed by any recommendations for further research. However, do not offer recommendations which could have been easily addressed within the study. This would demonstrate to the reader that you have inadequately examined and interpreted the data.
IV. Overall Objectives
The objectives of your discussion section should include the following: I. Reiterate the Research Problem/State the Major Findings
Briefly reiterate the research problem or problems you are investigating and the methods you used to investigate them, then move quickly to describe the major findings of the study. You should write a direct, declarative, and succinct proclamation of the study results, usually in one paragraph.
II. Explain the Meaning of the Findings and Why They are Important
No one has thought as long and hard about your study as you have. Systematically explain the underlying meaning of your findings and state why you believe they are significant. After reading the discussion section, you want the reader to think critically about the results and why they are important. You don’t want to force the reader to go through the paper multiple times to figure out what it all means. If applicable, begin this part of the section by repeating what you consider to be your most significant or unanticipated finding first, then systematically review each finding. Otherwise, follow the general order you reported the findings presented in the results section.
III. Relate the Findings to Similar Studies
No study in the social sciences is so novel or possesses such a restricted focus that it has absolutely no relation to previously published research. The discussion section should relate your results to those found in other studies, particularly if questions raised from prior studies served as the motivation for your research. This is important because comparing and contrasting the findings of other studies helps to support the overall importance of your results and it highlights how and in what ways your study differs from other research about the topic. Note that any significant or unanticipated finding is often because there was no prior research to indicate the finding could occur. If there is prior research to indicate this, you need to explain why it was significant or unanticipated. IV. Consider Alternative Explanations of the Findings
It is important to remember that the purpose of research in the social sciences is to discover and not to prove . When writing the discussion section, you should carefully consider all possible explanations for the study results, rather than just those that fit your hypothesis or prior assumptions and biases. This is especially important when describing the discovery of significant or unanticipated findings.
V. Acknowledge the Study’s Limitations
It is far better for you to identify and acknowledge your study’s limitations than to have them pointed out by your professor! Note any unanswered questions or issues your study could not address and describe the generalizability of your results to other situations. If a limitation is applicable to the method chosen to gather information, then describe in detail the problems you encountered and why. VI. Make Suggestions for Further Research
You may choose to conclude the discussion section by making suggestions for further research [as opposed to offering suggestions in the conclusion of your paper]. Although your study can offer important insights about the research problem, this is where you can address other questions related to the problem that remain unanswered or highlight hidden issues that were revealed as a result of conducting your research. You should frame your suggestions by linking the need for further research to the limitations of your study [e.g., in future studies, the survey instrument should include more questions that ask..."] or linking to critical issues revealed from the data that were not considered initially in your research.
NOTE: Besides the literature review section, the preponderance of references to sources is usually found in the discussion section . A few historical references may be helpful for perspective, but most of the references should be relatively recent and included to aid in the interpretation of your results, to support the significance of a finding, and/or to place a finding within a particular context. If a study that you cited does not support your findings, don't ignore it--clearly explain why your research findings differ from theirs.
V. Problems to Avoid
- Do not waste time restating your results . Should you need to remind the reader of a finding to be discussed, use "bridge sentences" that relate the result to the interpretation. An example would be: “In the case of determining available housing to single women with children in rural areas of Texas, the findings suggest that access to good schools is important...," then move on to further explaining this finding and its implications.
- As noted, recommendations for further research can be included in either the discussion or conclusion of your paper, but do not repeat your recommendations in the both sections. Think about the overall narrative flow of your paper to determine where best to locate this information. However, if your findings raise a lot of new questions or issues, consider including suggestions for further research in the discussion section.
- Do not introduce new results in the discussion section. Be wary of mistaking the reiteration of a specific finding for an interpretation because it may confuse the reader. The description of findings [results section] and the interpretation of their significance [discussion section] should be distinct parts of your paper. If you choose to combine the results section and the discussion section into a single narrative, you must be clear in how you report the information discovered and your own interpretation of each finding. This approach is not recommended if you lack experience writing college-level research papers.
- Use of the first person pronoun is generally acceptable. Using first person singular pronouns can help emphasize a point or illustrate a contrasting finding. However, keep in mind that too much use of the first person can actually distract the reader from the main points [i.e., I know you're telling me this--just tell me!].

Writing Tip
Don’t Over-Interpret the Results!
Interpretation is a subjective exercise. As such, you should always approach the selection and interpretation of your findings introspectively and to think critically about the possibility of judgmental biases unintentionally entering into discussions about the significance of your work. With this in mind, be careful that you do not read more into the findings than can be supported by the evidence you have gathered. Remember that the data are the data: nothing more, nothing less.

Another Writing Tip
Don't Write Two Results Sections!
One of the most common mistakes that you can make when discussing the results of your study is to present a superficial interpretation of the findings that more or less re-states the results section of your paper. Obviously, you must refer to your results when discussing them, but focus on the interpretation of those results and their significance in relation to the research problem, not the data itself.
Azar, Beth. "Discussing Your Findings." American Psychological Association gradPSYCH Magazine (January 2006).
Yet Another Writing Tip
Avoid Unwarranted Speculation!
The discussion section should remain focused on the findings of your study and their interpretation in relation to the research problem. For example, if the purpose of your research was to measure the impact of foreign aid on increasing access to education among disadvantaged children in Bangladesh, it would not be appropriate to speculate about how your findings might apply to populations in other countries without drawing from existing studies to support your claim or if analysis of other countries was not a part of your original research design. If you feel compelled to theorize about alternative outcomes, do so in the form of describing possible implications or explaining possible impacts. Be certain that you clearly identify your comments as speculation or as a suggestion for where further research is needed. Sometimes your professor will encourage you to expand your discussion of the results in this way, while others don’t care what your opinion is beyond your effort to interpret the results in relation to the research problem.

COMMENTS
You can organize your discussion around key themes, hypotheses, or research questions, following the same structure as your results section. Alternatively, you can also begin by highlighting the most significant or unexpected results.
A rigorous and concise discussion section is one of the keys to achieving an excellent paper. It serves as a critical platform for researchers to interpret and connect their findings with the broader scientific context.
Focus on unexpected, significant, or unusual findings. Highlight new trends, relationships, and knowledge uncovered by your research. List your analyses in the order in which the results section is based. If there are alternative explanations for your results, mention them and explain why you’ve excluded them. 4.
This guide provides possible statements to use when discussing specific types of content in the Discussion section of a research paper. These are examples of only some, but not all, of the phrases that can be used in the Discussion section of all APA Style papers.
The discussion section is one of the final parts of a research paper, in which an author describes, analyzes, and interprets their findings. They explain the significance of those results and tie everything back to the research question(s).
The discussion section contains the results and outcomes of a study. An effective discussion informs readers what can be learned from your experiment and provides context for the results.
In this blog, we look at how to write the discussion section of a research paper. We will go through plenty of discussion examples and understand how to construct a great discussion section for your research paper.
The examples below are from 72,017 full-text PubMed research papers that I analyzed in order to explore common ways to start writing the Discussion section. Research papers included in this analysis were selected at random from those uploaded to PubMed Central between the years 2016 and 2021.
The discussion section of a research paper analyzes and interprets the findings, provides context, compares them with previous studies, identifies limitations, and suggests future research directions.
The content of the discussion section of your paper most often includes: Explanation of results: Comment on whether or not the results were expected for each set of findings; go into greater depth to explain findings that were unexpected or especially profound.
