Responding to Peer Reviewer Comments: Strategies for Authors

Peer review doesn't end when the manuscript comes back — in many ways, that's where the real work begins. A response to reviewers is a formal document, a negotiation, and occasionally a test of patience, all at once. This page covers the structure and strategy of crafting effective author responses, from organizing a rebuttal letter to navigating disagreement with reviewers, with the goal of moving a manuscript toward acceptance without losing its scientific integrity.

Definition and scope

When a journal editor sends back a manuscript as "major revision," "minor revision," or even "reject and resubmit," authors receive a set of reviewer comments alongside. The response to those comments — formally called the author response letter or rebuttal letter — is a structured document in which authors address each critique point-by-point, explain changes made to the manuscript, and, where appropriate, respectfully push back on requests they believe are scientifically unwarranted.

This process is distinct from simply editing the manuscript. The response letter is read independently by the editor and re-reviewed by the original reviewers (in most cases). A sloppy or dismissive response letter can sink a manuscript that would otherwise have been accepted. According to guidance from the International Committee of Medical Journal Editors (ICMJE), authors retain the right to appeal editorial decisions and to explain their reasoning — but tone and precision are not optional.

The scope here covers all standard peer-review models: single-blind, double-blind, and open review, all of which require author responses upon revision. The peer review process explained page covers those model distinctions in detail.

How it works

A typical author response letter follows a consistent architecture, regardless of discipline.

  1. Opening acknowledgment — A brief, professional statement thanking the evaluators and editor for their time. One or two sentences. Not obsequious.
  2. Point-by-point breakdown — Each reviewer comment is quoted verbatim (or paraphrased clearly), followed immediately by the author's response and the specific change made to the manuscript (with page and line numbers referencing the revised version).
  3. Tracked manuscript — Submitted alongside the letter, usually with changes marked in a different color or using Track Changes. Some journals require a clean version and a marked version simultaneously.
  4. Summary of major changes — An optional but useful introductory paragraph listing the 3–5 most substantive changes before diving into specifics.

The convention of quoting reviewers verbatim, then responding, exists for a practical reason: editors reviewing responses don't want to flip between two documents. The letter should be self-contained. A well-formatted response to a manuscript with 3 reviewers and an average of 8 comments each produces a document of 15–30 pages — not unusual for major revisions in fields like open access publishing in science, where transparent review records are increasingly shared publicly.

Common scenarios

Scenario 1: The legitimate critique
A reviewer identifies a statistical error, a missing control, or an overclaimed conclusion. The correct response: acknowledge the problem directly, explain the correction, point to the revised text. Authors who try to rationalize the original error rather than fix it lose credibility with editors fast.

Scenario 2: The redundant experiment request
A reviewer requests a new experiment that would require 6 months of additional work. This is common, and authors have options. If the experiment is genuinely beyond the scope of the current manuscript, a polite but substantive rebuttal explaining why — backed by citations or logic — is appropriate. Many journals, particularly those with guidance aligned with research ethics and publication standards, expect authors to engage honestly rather than agree to work they cannot deliver.

Scenario 3: The contradictory reviewers
Reviewer 1 wants the discussion section shortened. Reviewer 2 wants it expanded. This happens with notable regularity. The correct strategy is to address both comments transparently, explain the compromise reached, and note the competing requests in the response letter. Editors appreciate honesty over gymnastics.

Scenario 4: The factually incorrect reviewer comment
Occasionally, a reviewer misremembers the literature or misreads the methods. Authors can — and should — respectfully correct the record, citing specific sources. The operative word is "respectfully." The response letter is not the venue for contempt, regardless of how wrong the evaluator is.

Decision boundaries

The central decision in any revision is whether to comply with a request, modify and partially comply, or decline and explain why. These are not equally weighted options.

Comply when an evaluator has identified a genuine weakness, even if it stings. The manuscript will be stronger for it.

Partially comply when a request is directionally valid but the full version is impractical or scientifically inappropriate — and the partial change genuinely addresses the underlying concern.

Decline only with a substantive scientific rationale, never on the basis of preference or inconvenience. A decline supported by 3 published, refereed citations carries weight. A decline that reads as impatience does not.

One meaningful contrast: minor revision responses versus major revision responses. A minor revision response is typically 2–5 pages, addresses small clarifications and formatting issues, and usually does not require re-review. A major revision response may be 30+ pages, involves substantive new analysis, and almost always returns to at least one original reviewer. Conflating the two — producing a cursory response for a major revision — is one of the faster ways to accumulate rejections.

The manuscript submission process is where authors first learn a journal's specific requirements for formatting and submitting revision packages. Those requirements vary: some journals use submission portals with structured response fields; others accept free-form documents. Either way, the underlying logic of engaging honestly, specifically, and completely with reviewer comments holds across the broader landscape of scientific publishing covered throughout the Scientific Journal Authority index.
