What is peer review?
Peer review is the process in which independent expert reviewers assess a scientific study.
It is not usually as simple as “reviewers read and decide.”
Critical steps often happen before reviewers and at the editor’s desk.
Peer review process for editors
Editors run peer review as a workflow, not a single “send to reviewers” button. At screening they decide scope, novelty signal, and whether the manuscript meets basic reporting standards. Only papers that pass triage are assigned reviewers; the editor then synthesizes conflicting reports into accept, revision, or reject.
Editor-side steps authors should understand:
- Initial triage — fit with aims, obvious flaws, ethics flags (desk reject if it fails).
- Reviewer invitation — experts without conflicts; delays here slow the whole process.
- Decision letter — major/minor revision or rejection based on reports plus editorial judgment.
Authors who map their draft to this workflow before submission reduce avoidable triage failures. See pre-submission manuscript screening for a practical checklist.
What are the stages of peer review?
1. Editorial triage
The editor evaluates scope, contribution, and overall structure.
Manuscripts that fail here receive a desk reject.

What is a desk reject?2. Reviewer selection
The editor sends the paper to reviewers who are expert and free of conflicts.
Selection affects speed and decision quality.
3. Reviewer evaluation
Reviewers assess contribution, methods, analysis, discussion, and ethics.
They may recommend:
- major revision
- minor revision
- rejection

4. Editorial decision
The editor makes the final call after reviews.
Editors need not accept every reviewer recommendation—they balance differing views.
Common mistakes during peer review
- Taking comments personally
- Careless response letters
- Confusing major and minor revision
- Misreading the editor’s message
These can lead to rejection after revision.
How long does peer review take?
Timing depends on journal, field, and reviewer responsiveness.
For many authors, the hardest part is uncertainty.
Reducing that uncertainty starts with reviewer/editor-style evaluation before submission.
What can you do before peer review starts?
- Clarify methods
- State contribution clearly
- Balance claims in the discussion
This materially lowers major revision and rejection risk.
How pre-submission review helps
It makes visible:
- editor-desk risks
- likely reviewer friction points
Conclusion
Peer review is not random—it has expectations and patterns.
Understanding the process matters as much as writing the paper.
