Receiving peer review comments on a submitted paper is one of the most emotionally charged moments in a researcher’s academic life. After months of work designing, conducting, analysing, and writing up a study, the response from reviewers can feel deeply personal — particularly when comments are critical, contradictory, or appear to fundamentally misunderstand what you were trying to do.
The ability to respond to peer review comments professionally, thoroughly, and strategically is one of the most important skills in academic publishing — and one of the least formally taught. Most PhD students receive their first set of reviewer comments with no guidance on how to handle them, no understanding of what the review process actually means, and no framework for writing a response that maximises the chance of acceptance.
This guide will show you exactly how to respond to peer review comments — what the different decision outcomes mean, how to read and interpret reviewer feedback, how to write a professional response letter, how to handle specific types of difficult comments, and the most common mistakes researchers make in the revision process.
Understanding the Peer Review Process
Before addressing how to respond to reviewer comments, it is important to understand what peer review is, how it works, and what the different editorial decisions actually mean. This context transforms how you read and respond to feedback.
What is peer review?
Peer review is the process by which a submitted manuscript is evaluated by independent experts in the relevant field before a decision is made about publication. It is the primary quality control mechanism in academic publishing — ensuring that published research meets the standards of the field in terms of methodology, originality, significance, and scholarly integrity.
Most journals use double-blind peer review — neither the authors nor the reviewers know each other’s identities. Some journals use single-blind review where reviewers know the authors’ identities but authors do not know the reviewers. An increasing number of journals use open peer review where identities are known to both parties and reviews may be published alongside the paper.
The four possible editorial decisions
After peer review, the editor communicates one of four possible decisions:
Accept as submitted — the paper is accepted without any changes required. This outcome is extremely rare — fewer than 5% of papers in most journals. Even papers that are ultimately accepted almost always go through at least one round of revision.
Minor revisions — the paper is of sufficient quality for publication but requires specific, limited changes — clarifications, additional data, corrected errors, or improved presentation. The expectation is that revisions can be completed quickly (typically two to four weeks) and are unlikely to require further review.
Major revisions — the paper has potential for publication but requires substantial changes — additional data collection or analysis, significant restructuring, more thorough engagement with the literature, or fundamental methodological issues to address. Major revisions typically allow two to three months for completion and usually go back to the original reviewers after submission.
Reject — the paper is not suitable for publication in this journal. Rejection may be due to insufficient originality, serious methodological flaws, poor fit with the journal’s scope, or writing quality below the required standard. A rejection from one journal does not mean the paper cannot be published — it is an invitation to revise and submit elsewhere.
What a major revisions decision actually means
Many PhD students and early-career researchers interpret a major revisions decision as a near-rejection — a polite way of saying the paper is not good enough. This interpretation is incorrect and leads to either abandonment of perfectly good research or inadequate revision effort.
A major revisions decision means the editor and reviewers believe the paper has sufficient merit to be worth their continued time and attention. It is an investment — reviewers have spent hours reading your paper and writing substantive feedback. That investment would not happen for a paper the editor did not think could eventually be published.
Treat a major revisions decision as a conditional acceptance with conditions attached. The conditions are the reviewer comments. Meet them thoroughly and you significantly increase your chances of acceptance.
The First Read — How to Process Reviewer Comments
Do not respond immediately
The moment you receive reviewer comments — particularly critical ones — is not the moment to begin writing your response. The immediate emotional reaction to criticism of work you have invested months in is often one of defensiveness, hurt, or anger. None of these emotional states produces good academic writing.
Read the comments through once to understand the overall picture. Then close the document and leave it for at least 24 hours — preferably 48. Return to it when you are in a calm, analytical state of mind. You will read the comments differently on a second or third reading — less personally, more strategically.
Separate the signal from the noise
Peer reviewers are human. Their comments vary enormously in quality, specificity, and usefulness. Some comments are highly specific, technically detailed, and directly actionable. Others are vague, contradictory, or reflect a misunderstanding of what you were trying to do. A small number may reflect the reviewer’s personal preferences rather than genuine methodological concerns.
Your task is to identify the signal — the substantive, valid concerns that genuinely improve the paper — and respond to every comment, including those you disagree with, in a way that satisfies the editor.
Create a master list of every comment
Before writing a single word of your response, go through each reviewer’s feedback and create a numbered list of every distinct comment or request. This serves two purposes — it ensures you do not miss any comment in your response, and it transforms what may feel like an overwhelming wall of criticism into a manageable, finite list of specific tasks.
Number the comments consecutively within each reviewer’s section — Reviewer 1 Comment 1, Reviewer 1 Comment 2, and so on. This numbering system becomes the structure of your response letter.
Categorise each comment
Once you have your master list, categorise each comment into one of four types:
Straightforward revisions — changes you agree with and can make without difficulty. These include factual errors to correct, clarifications to add, additional references to include, and presentational improvements to make.
Substantial revisions — changes that require significant additional work — additional analysis, new data collection, major restructuring, or extensive rewriting. These need careful planning before you begin.
Contested comments — points you disagree with or where you believe the reviewer has misunderstood your work. These require a carefully crafted response that respectfully explains your position while demonstrating that you have taken the concern seriously.
Contradictory comments — cases where two reviewers have asked for opposite things, or where a reviewer’s request contradicts your research design or your field’s conventions. These require diplomatic navigation in your response.
The Response Letter — Structure and Format
The response letter — also called the rebuttal letter or the author response — is the document you submit alongside your revised manuscript that addresses every reviewer comment explicitly. It is one of the most important documents you will write in the publication process.
The editor reads your response letter carefully. A thorough, respectful, clearly structured response letter significantly increases your chances of acceptance — regardless of the actual revisions made to the manuscript. A dismissive, incomplete, or defensive response letter can result in rejection even when the manuscript revisions themselves are adequate.
The structure of a professional response letter
Opening paragraph — thank the editor and reviewers:
Begin with a brief, genuine expression of gratitude for the reviewers’ time and the quality of their feedback. This is not sycophancy — it is professional acknowledgement that reviewers spend significant unpaid time providing feedback that genuinely improves published research.
Dear [Editor name],
We are grateful to the editor and reviewers for their careful reading
of our manuscript and for the constructive and detailed feedback
provided. The comments have substantially improved the paper and we
believe the revised manuscript addresses all concerns raised.
We provide below a point-by-point response to each reviewer comment.
All changes to the manuscript are highlighted in yellow in the
revised document for the editor’s and reviewers’ convenience.
Overview of major revisions (optional but recommended for major revisions):
For major revisions decisions, a brief paragraph summarising the most significant changes made provides a helpful overview before the detailed point-by-point response.
Point-by-point response to each reviewer:
This is the main body of the response letter. Address every comment from every reviewer, numbered consistently with your master list. For each comment, follow this three-part structure:
- Quote or paraphrase the reviewer comment — so the editor can follow the response without having to cross-reference the original review
- State your response — whether you have made the requested change, and why or why not
- Show where the change is in the manuscript — with specific page and line numbers in the revised manuscript
Closing paragraph:
A brief closing thanking the editor and expressing your hope that the revised manuscript now meets the journal’s requirements.
How to Respond to Different Types of Comments
Responding to comments you agree with
For comments you agree with and have addressed in full, the response is direct and specific:
Reviewer 1, Comment 3:
Reviewer comment: “The sample size justification is insufficient.
The authors should provide a power analysis to justify the sample
of 150 participants.”
Response: We agree with this comment and have added a formal power
analysis to the methodology section. Using G*Power software with
an effect size of f² = 0.15 (medium), α = .05, and power = .80,
the minimum required sample was calculated as 139 participants.
Our sample of 150 therefore meets the required threshold. This
analysis has been added to page 8, lines 214–221 of the revised
manuscript.
Notice the response: acknowledges the comment directly, states the action taken, provides the specific detail of what was done, and gives the exact location in the revised manuscript.
Responding to comments you partially agree with
Some reviewer comments identify a genuine concern but propose a solution that is not feasible or appropriate for your study. In this case, acknowledge the concern, explain why the specific suggestion cannot be implemented, and describe what alternative action you have taken to address the underlying concern.
Reviewer 2, Comment 5:
Reviewer comment: “The qualitative sample of 15 participants is
too small. The authors should interview at least 30 participants
to ensure saturation.”
Response: We appreciate this concern and agree that sample size
is an important consideration in qualitative research. However,
we respectfully note that sample size in qualitative research
is determined by theoretical saturation rather than by a fixed
minimum threshold. Our data collection followed an iterative
process in which no new themes emerged after the 12th interview,
consistent with the saturation criteria recommended by Braun and
Clarke (2021). We have strengthened the discussion of this
decision in the methodology section (page 10, lines 267–275),
adding explicit reference to the saturation criterion and how
it was assessed. We have also acknowledged the sample size as
a limitation in the revised discussion (page 19, lines 498–503).
Responding to comments you disagree with
Disagreeing with a reviewer comment is legitimate — reviewers are not infallible and their suggestions do not always improve a paper. However, the way you express disagreement is critical. A dismissive or confrontational response alienates the editor and reviewer. A well-reasoned, respectful, evidence-based argument for your position is both professionally appropriate and often persuasive.
The key principle: always assume the reviewer’s concern is valid even if you disagree with their conclusion. Understand what is driving their concern before responding to it.
Reviewer 1, Comment 7:
Reviewer comment: “The authors should use structural equation
modelling rather than regression analysis for this dataset,
as SEM would better capture the latent variable structure.”
Response: We appreciate the reviewer’s methodological expertise
and have carefully considered this suggestion. We respectfully
maintain our use of hierarchical regression for two reasons.
First, our sample size of 150 is at the lower bound for SEM
estimation with our model’s degree of complexity — simulation
studies suggest a minimum of 200 cases for models with this
number of parameters (Wolf et al., 2013). Second, our research
objectives concern the relative predictive contribution of
individual variables — a question more directly addressed by
regression coefficients than by SEM path coefficients. We have
added a discussion of this methodological choice to the
methodology section (page 9, lines 241–249), acknowledging
SEM as a direction for future research with larger samples.
The structure: acknowledge the comment seriously, state your position clearly, provide specific evidence or reasoning for your position, show the action you have taken to address the underlying concern, and suggest future research where relevant.
Responding to contradictory comments from different reviewers
When two reviewers ask for opposite things — Reviewer 1 says the literature review is too long and Reviewer 2 says it should be expanded — you face a genuine dilemma. You cannot satisfy both requests simultaneously.
In this situation, acknowledge both comments explicitly, explain the contradiction, and describe the decision you made and why. The editor is aware that contradictory reviewer feedback exists and will not penalise you for not satisfying contradictory requests — but they will expect you to have engaged with both.
Reviewer 1, Comment 2 AND Reviewer 2, Comment 4 (contradictory):
Reviewer 1 comment: “The literature review is excessively long
and should be reduced by approximately 30%.”
Reviewer 2 comment: “The authors should expand their engagement
with the theoretical literature on self-determination theory,
which is currently underdeveloped.”
Response: We note that Reviewers 1 and 2 offer contrasting
suggestions regarding the literature review. After careful
consideration, we have taken the following approach: we have
expanded the discussion of self-determination theory as requested
by Reviewer 2 (adding approximately 350 words at pages 5–6),
while simultaneously condensing other sections of the literature
review that are less directly relevant to our research questions
— specifically reducing the historical overview section by
approximately 400 words. The overall length of the literature
review is therefore broadly similar to the original, but the
theoretical focus has been sharpened in response to both
reviewers’ concerns.
Responding to vague or unclear comments
Some reviewer comments are insufficiently specific to act on directly — for example, “the methodology section needs strengthening” without specifying what is missing or weak. In this case, make a reasonable interpretation of what the reviewer may have intended, state your interpretation clearly, and describe what you have done based on that interpretation.
Reviewer 2, Comment 8:
Reviewer comment: “The discussion section needs to be more
analytical.”
Response: We interpret this comment as suggesting that the
discussion should engage more explicitly with the theoretical
implications of our findings rather than primarily describing
what was found. In response, we have substantially rewritten
the discussion section, adding explicit interpretation of each
major finding in relation to the theoretical framework,
expanding our engagement with contradictory findings in the
existing literature, and strengthening the theoretical
implications section. These revisions appear throughout the
discussion chapter (pages 17–23) and represent the most
substantial revision made in this round.
Responding to comments that involve additional data collection
Major revisions sometimes include requests for additional data — new experiments, additional interviews, expanded survey administration, or supplementary analyses. Before agreeing to collect additional data, consider whether it is feasible within the revision timeframe allowed by the journal, whether it would genuinely improve the paper or merely satisfy a reviewer preference, and whether your research design allows for it ethically and practically.
If additional data collection is genuinely not feasible, explain this clearly and offer an alternative — additional analysis of existing data, a clear acknowledgement of the limitation, or a reframing of the conclusions to more accurately reflect the data you have.
If the requested analysis is possible with existing data but was not originally performed, do it — even if you initially considered it unnecessary. Reviewers often ask for additional analyses that genuinely strengthen the paper.
Marking Changes in the Revised Manuscript
The revised manuscript submitted with your response letter should clearly mark all changes so that the editor and reviewers can verify that the revisions have been made without reading the entire paper from scratch.
The most widely used method is to highlight all changes in the manuscript using a different colour — yellow is conventional — or to use track changes in Microsoft Word. Your response letter should tell the editor which method you have used.
For substantial rewrites where track changes would make sections unreadable, use a brief note in the response letter: “This section has been substantially rewritten — the revised version appears on pages 14–17 of the revised manuscript.”
For changes to data, figures, or tables — note the specific table or figure number and describe what was changed.
Some journals have specific requirements for how revisions should be marked — always check the journal’s revision submission guidelines before preparing your revised manuscript.
Practical Tips for the Revision Process
Start with the straightforward revisions
Begin your revision process with the comments you agree with and can address quickly — factual corrections, additional references, clarification of terminology. Completing these first gives you momentum and reduces the overall length of your remaining task list, making the more difficult revisions feel more manageable.
Keep a revision log
As you work through revisions, keep a running log of every change made, where it appears in the manuscript (page and line number), and which reviewer comment it addresses. This log becomes the basis of your response letter — much easier to write from a running log than from memory after the revisions are complete.
Re-read the reviewer comments after revisions are complete
Once you have completed all revisions and written your response letter, re-read the original reviewer comments one more time and compare them against your response letter. Check that every comment is addressed, that your description of the revision accurately describes what you actually did, and that the page and line numbers cited in the response are correct.
Have your supervisor or a colleague read the response letter
Ask your supervisor or a trusted colleague to read your response letter before submission — particularly for major revisions decisions. A second reader often catches missed comments, identifies overly defensive language, and notices where explanations are unclear or insufficiently detailed.
Meet the revision deadline — or request an extension
Journals set revision deadlines — typically two to four weeks for minor revisions and two to three months for major revisions. Missing the deadline without communication is unprofessional and may result in the paper being treated as a new submission. If you genuinely cannot meet the deadline, contact the editorial office before it passes and request an extension. Most journals will grant a reasonable extension if asked in advance.
Common Mistakes in Responding to Peer Review
Being defensive or dismissive. Responding to critical comments with phrases like “the reviewer has clearly misunderstood our approach” or “this comment is not relevant to our research” signals to the editor that you have not engaged seriously with the feedback. Even comments you disagree with deserve a respectful, substantive response.
Failing to address every comment. Every comment — including minor ones — must receive an explicit response. Missing even a single comment suggests you have not read the feedback carefully or are selectively avoiding uncomfortable requests. Reviewers and editors notice omissions.
Vague revision descriptions. Responses like “we have revised the methodology section as suggested” without specifying what was changed, where the changes appear, and why they address the reviewer’s concern are insufficient. Be specific — quote the change you made, give the page and line number, and explain why it addresses the concern.
Agreeing to everything without judgment. Accepting every suggestion uncritically — including those that would weaken the paper or contradict your research design — is not professional revision. Reviewers do not expect authors to agree with everything. They expect authors to engage thoughtfully with every comment and to implement changes that genuinely improve the paper.
Taking too long to revise. Procrastinating on a revision while the emotional sting of critical feedback fades is understandable but counterproductive. Papers left unrevised for months are harder to re-engage with, revision deadlines can lapse, and the research may become less current. Set a revision schedule and stick to it.
Not tracking changes in the manuscript. Submitting a revised manuscript without marking the changes requires the editor and reviewers to read the entire paper again to identify what was revised. This is unnecessarily burdensome and creates a negative impression of your professionalism. Always mark changes clearly.
Treating the response letter as a formality. Some researchers write minimal response letters — a few sentences per comment — and invest all their effort in the manuscript revisions. The response letter is as important as the manuscript revisions. An editor who cannot follow what changes were made and why they address the reviewers’ concerns cannot make a confident acceptance decision.
After Submitting Your Revision — What Happens Next
After you submit your revised manuscript and response letter, the typical process is as follows:
The editor reads your response letter and makes an initial assessment of whether the revisions appear adequate. For minor revisions, the editor may make a decision without sending the paper back to reviewers. For major revisions, the paper usually goes back to the original reviewers — though editors sometimes make the decision themselves if the revisions are straightforward.
Typical timeframes for a decision after resubmission range from two to eight weeks for minor revisions to six to twelve weeks for major revisions where the paper must go back to reviewers.
Possible outcomes after resubmission include: accept as submitted, accept with minor revisions (requiring small corrections before final acceptance), further revisions required (a second round of major or minor revisions), or reject. A second-round rejection after major revisions is disappointing but not uncommon — if it happens, read the reviewers’ remaining concerns carefully, assess whether they are addressable with further revision or indicate a fundamental incompatibility with the journal’s requirements, and decide whether to revise and resubmit or submit elsewhere.

Frequently Asked Questions
How long should a response letter be? There is no fixed length — the response letter should be as long as needed to address every comment thoroughly. For minor revisions with five to ten comments, a response letter of two to four pages is typical. For major revisions with twenty to forty comments across two or three reviewers, response letters of eight to fifteen pages or more are common. Do not artificially compress the response to make it shorter — thoroughness is more important than brevity.
What if I genuinely cannot make a requested revision? If a revision is genuinely not feasible — for example, if additional data collection is impossible due to ethical constraints, the study population no longer being accessible, or resource limitations — explain this clearly and honestly in your response. Offer the best available alternative — additional analysis of existing data, a clearer acknowledgement of the limitation, or a reframing of the conclusions. Editors understand that not every revision is feasible and will accept a well-reasoned explanation.
Should I respond to editor comments and reviewer comments differently? In principle, use the same respectful, thorough approach for both. In practice, editor comments often identify the most critical concerns — the issues that will determine the accept/reject decision — so these should receive particular attention. If the editor’s decision letter identifies specific concerns beyond the reviewers’ comments, address those explicitly at the top of your response letter before the reviewer-by-reviewer responses.
What if the reviewer is clearly wrong about a factual matter? Politely and specifically correct the error, citing the relevant evidence or literature. Do not be dismissive — acknowledge that the comment raises a point worth clarifying, then provide the correct information with appropriate citations. Use language like: “We respectfully note that [accurate statement], as demonstrated by [citation]. We have added a clarification at [page, line] to prevent this misunderstanding in future readers.”
Is it acceptable to submit to another journal after a rejection without major revision? Yes — rejection from one journal does not prevent submission to another. However, if the rejection letter or reviewers identified significant methodological or conceptual concerns, it is advisable to address these before resubmitting elsewhere. A paper that is rejected from multiple journals for the same reasons without revision is unlikely to eventually be accepted. Read the rejection carefully — it often contains genuinely useful guidance for improving the paper before the next submission.
How do I handle a reviewer who appears to have read my paper superficially? Respond as if the comment is well-intentioned regardless of how it appears. Reviewers occasionally write comments that seem superficial or that misrepresent what you wrote. In your response, politely clarify what you actually did or said, point to the specific location in the manuscript where this is addressed, and if the comment suggests a lack of clarity in the original writing, note that you have revised for clarity at the relevant point.
Conclusion
Responding to peer review comments is one of the most challenging and most important skills in academic publishing. The research that gets published is not always the research with the strongest first submission — it is often the research whose authors engage most constructively, persistently, and professionally with the revision process.
Every round of peer review — even a rejection — contains information that can make your research and your writing better. The researchers who publish most consistently are those who have learned to read reviewer feedback without defensiveness, to distinguish valid concerns from personal preferences, to respond with precision and respect, and to persist through the revision process with patience and professionalism.
The framework in this guide — understanding the decision, processing the feedback, structuring the response letter, addressing each comment type, and avoiding the common mistakes — provides everything you need to approach any peer review response with confidence.
