Receiving peer review comments is an important stage in academic publishing. After investing considerable time in conducting research and preparing a manuscript, authors may feel excited when a journal sends its decision. However, that excitement can quickly turn into uncertainty when the reviewers request substantial changes, question the methodology, or point out weaknesses in the discussion.
Such feedback is a normal part of scholarly communication. Even well-prepared manuscripts can require clarification, additional analysis, improved explanations, or corrections before they are suitable for publication. The way authors respond to these comments can influence how editors and reviewers assess the revised manuscript.
Responding successfully does not mean agreeing with every suggestion. Instead, it involves understanding the feedback, evaluating each recommendation carefully, making appropriate revisions, and explaining decisions clearly and professionally.
This guide explains how researchers can prepare an effective response to peer review comments, manage difficult criticism, organise manuscript revisions, and improve their chances of progressing towards publication.
1. Understand the Editor's Decision Before Revising
Before making changes to the manuscript, read the editor's decision letter carefully. Journals generally communicate one of several outcomes: acceptance, minor revision, major revision, rejection, or rejection with an invitation to submit a substantially revised manuscript.
Each decision requires a different response.
A minor revision may involve correcting references, clarifying a statement, improving a figure, or addressing a few concerns. A major revision may require a more detailed response, including additional analysis, a stronger explanation of the research methodology, or substantial changes to the discussion.
The editor's instructions should guide the revision process. Pay attention to the deadline, requested files, formatting requirements, and whether the journal expects a separate response letter.
Do not assume that every reviewer comment carries the same weight. An editor may highlight particular concerns that must be addressed before the manuscript can be reconsidered.
Practical tip: Read the decision letter once for the overall assessment and again to identify specific tasks. Make a list of all requirements before editing the paper.
2. Read All Reviewer Comments Without Responding Immediately
Reviewer feedback can be difficult to receive, especially when comments appear negative or overly critical. Nevertheless, an immediate defensive response rarely helps the revision process.
Read all the comments first, including those from the editor and every reviewer. Some reviewers may identify overlapping problems, while others may focus on different aspects of the study.
For example, one reviewer might question the sample size, while another may ask for a clearer explanation of the statistical analysis. These comments may be related and could be addressed through a coordinated revision.
Separate the comments into practical categories:
- Methodology: Research design, sampling, experimental procedures, instruments, and data analysis.
- Results: Missing information, unclear findings, statistical interpretation, or inconsistent data.
- Discussion: Unsupported interpretations, insufficient comparison with previous research, or limited explanation of findings.
- Presentation: Language, structure, figures, tables, and formatting.
- References: Missing citations, outdated sources, or incorrect bibliographic information.
- Research limitations: Questions about generalisability, study constraints, or the significance of the contribution.
This classification helps transform a lengthy review into a manageable revision plan. If you are also preparing new material in response to reviewer requests, our guide on how to write a systematic literature review using the PRISMA guide can help you strengthen the literature review section.
3. Prepare a Point-by-Point Response Document
One of the most effective ways to respond to peer review comments is to prepare a separate document addressing every comment individually.
Avoid writing a single paragraph claiming that all suggestions have been incorporated. Editors need to understand exactly what was changed and how each concern was addressed.
A point-by-point response typically includes three elements:
- The original reviewer comment.
- The author's response.
- The specific change made to the manuscript, including the relevant section, page, or line numbers where possible.
For example:
Reviewer comment: The research objectives are not clearly stated in the introduction.
Author response: Thank you for highlighting this issue. We have revised the final paragraph of the introduction to state the research objectives more explicitly and explain their relationship to the identified research gap.
Revision made: The objectives have been clarified in the final paragraph of the Introduction, on page 3 of the revised manuscript.
This format makes it easier for the editor to verify the changes without repeatedly searching through the manuscript.
If a comment contains several separate requests, divide it into smaller points and answer each one. A response that addresses only part of a comment may leave the reviewer uncertain about whether the issue has been resolved.
4. Maintain a Respectful and Professional Tone
The language used in a response letter matters. Reviewers may misunderstand a sentence, disagree with an interpretation, or recommend changes that the authors believe are unnecessary. Even in such situations, responses should remain courteous and focused on the research.
Begin by acknowledging the reviewer's effort where appropriate. You do not need to praise every comment, but you should recognise useful observations and explain your decisions professionally.
Consider the difference between these responses.
Unhelpful response:
"The reviewer has misunderstood our study. This comment is incorrect."
More constructive response:
"We appreciate the reviewer's observation. We recognise that the original explanation may not have communicated this point clearly. We have revised the relevant paragraph to clarify the scope of the study and explain the reasoning behind our approach."
The second response addresses the concern without blaming the reviewer.
Professional language is particularly important when reviewers disagree with the research design or question the significance of the findings. Explain the reasoning behind your decisions using evidence, methodological justification, and relevant literature.
Remember that the purpose of the response is not to win an argument. It is to help the editor determine whether the manuscript has adequately addressed the concerns raised during peer review.
5. Revise the Manuscript, Not Just the Response Letter
A common mistake is to write a convincing response without making the corresponding change to the manuscript.
If a reviewer requests a clearer explanation of the sampling procedure, the response letter should describe the change, and the methodology section should contain the revised explanation.
Similarly, if a reviewer identifies a limitation in the interpretation of results, the discussion may need to be updated to reflect that limitation.
After making each revision, check that the response letter accurately describes the change. Page and line numbers should refer to the final revised version, not an earlier draft.
Track changes can be helpful when the journal permits or requests them. Some journals also require a clean manuscript without visible editing marks. Follow the journal's instructions and prepare both versions when necessary.
A useful practice is to maintain a revision checklist containing the reviewer comment, the action taken, the manuscript location, and the status of the change. This reduces the likelihood of overlooking a small but important request.
6. How to Respond When You Disagree with a Reviewer
Authors are not required to accept every reviewer recommendation. Sometimes a suggested analysis is unsuitable for the research question, a proposed interpretation conflicts with the evidence, or a recommendation would expand the manuscript beyond its intended scope.
However, disagreement should be supported by a clear explanation rather than a simple refusal.
For example:
Reviewer comment: The authors should include an additional experimental group to strengthen the conclusions.
Author response: We thank the reviewer for this suggestion. We agree that an additional experimental group could provide useful information. However, the present study was designed to investigate the specified research question using the groups described in the methodology. Because the proposed group was not included in the original experimental design, we have clarified this limitation in the revised discussion and moderated the conclusions accordingly.
This response acknowledges the potential value of the suggestion while explaining why it cannot be implemented.
Where appropriate, authors may offer an alternative. They could include a supplementary analysis, add a methodological explanation, discuss the limitation, or identify the proposed work as a direction for future research.
Avoid making unsupported claims that the reviewer is wrong. A strong disagreement is based on evidence, not emotion.
7. Address Requests for Additional Experiments or Analysis
Requests for additional analysis can be among the most challenging aspects of a major revision. Before deciding how to respond, determine whether the requested work is necessary to support the manuscript's main conclusions.
If the analysis can be completed reliably using the available data, conduct it and report the results transparently. Explain the method used, present the findings, and update the relevant tables, figures, or discussion.
If the request involves new experiments, additional participants, or data that were never collected, consider whether the work is feasible within the revision period and whether it is essential to the central research claim.
When a requested analysis cannot be performed, explain the limitation clearly. Do not invent results, imply that an experiment was conducted when it was not, or present speculative findings as established evidence.
For example:
"We appreciate the reviewer's recommendation to conduct an additional validation experiment. This experiment was not included in the present study, and the required measurements are not available in the existing dataset. We have acknowledged this limitation and revised the conclusion to avoid making claims that would require the additional validation."
Such a response may not satisfy every reviewer, but it preserves research integrity and communicates the limitation honestly.
8. Strengthen the Introduction, Discussion, and Literature Review
Reviewers frequently request improvements to the introduction and discussion because these sections explain why the research matters and how its findings contribute to existing knowledge.
If a reviewer asks for a stronger research gap, do more than add several citations. Explain what previous studies have established, what remains unresolved, and how the present investigation addresses that issue.
When new references are requested, read the relevant papers before citing them. Confirm that they support the statement for which they are being used.
Similarly, a request to improve the discussion may require a deeper interpretation of the findings rather than simply repeating the results. Explain how the findings compare with previous studies, consider plausible reasons for similarities or differences, and acknowledge alternative explanations where appropriate.
If the reviewer questions the novelty of the research, identify the manuscript's specific contribution. This might involve a new dataset, a different experimental setting, a methodological improvement, a theoretical insight, or evidence that challenges an established assumption.
Avoid overstating novelty. A clear and defensible contribution is more persuasive than broad claims that a study is the first of its kind without sufficient evidence. For help structuring this section, see our guide on how to write a good literature review for a research paper.
9. Handle Conflicting Reviewer Comments Carefully
Occasionally, two reviewers recommend opposite changes. One may ask for a shorter discussion, while another requests a more detailed interpretation. One may suggest adding references, whereas another considers the literature review too long.
In such cases, consider the underlying purpose of each recommendation rather than following both literally.
You might shorten repetitive explanations while adding a focused paragraph addressing the missing interpretation. Similarly, you can replace less relevant references with more directly related studies instead of simply increasing the number of citations.
If the recommendations cannot be reconciled, explain the approach taken in the response letter. Where necessary, the editor can provide direction on conflicting requests.
The key is to demonstrate that each comment was considered thoughtfully and that the final manuscript remains coherent.
10. Common Mistakes to Avoid During Revision
Even a strong study can be weakened by an incomplete or poorly organised revision. Researchers should avoid the following mistakes:
Ignoring difficult comments: Every substantive comment should receive a response, even when the authors disagree with the recommendation.
Providing vague answers: Statements such as "Corrected as suggested" offer little information. Explain what changed and where.
Changing the manuscript without updating the response letter: Inconsistencies make the revision harder to assess.
Adding citations without checking them: Every new reference should be relevant, accurate, and consulted by the authors.
Overlooking minor corrections: Grammar, units, figure labels, abbreviations, and formatting can also affect the quality of the manuscript.
Missing the deadline: If additional work makes the deadline unrealistic, contact the editorial office before it expires and request an extension with a reasonable explanation. Approval is at the journal's discretion.
Making unsupported changes to the results: Revisions should improve clarity and scientific validity, not alter findings to satisfy a reviewer.
Careful organisation and a final quality check can prevent many of these problems.
11. Final Checklist Before Resubmitting Your Manuscript
Before uploading the revised paper, review the following items:
- Every editor and reviewer comment has been addressed.
- Each response explains the action taken or provides a reason for not implementing the suggestion.
- All stated revisions appear in the manuscript.
- Page, section, and line references are accurate.
- New analyses, figures, and tables are correctly labelled and discussed.
- All new citations appear in the reference list and bibliographic details have been verified.
- The abstract, results, discussion, and conclusion remain consistent.
- The revised manuscript follows the journal's formatting requirements.
- Required response letters, supplementary files, and clean or tracked-change versions are included.
- The files have been checked for errors before submission.
Completing this checklist helps ensure that the revised submission is consistent, complete, and ready for editorial assessment.
Responding to peer review comments is an essential part of developing a stronger research paper. Although the process can involve substantial work, it gives authors an opportunity to clarify their methods, strengthen their arguments, address limitations, and communicate their findings more effectively.
Successful revision depends on more than making the requested changes. Researchers should respond to every comment systematically, maintain a respectful tone, support disagreements with evidence, and ensure that the response letter accurately reflects the revised manuscript.
Not every revision results in acceptance, because the final decision depends on the journal's standards and the editor's assessment. Nevertheless, a carefully prepared response demonstrates scholarly responsibility and makes it easier for reviewers to evaluate the work.
By approaching reviewer feedback as a structured academic discussion rather than a personal criticism, researchers can make the revision process more productive and improve the overall quality of their manuscripts.
