Peer review is the process whereby scholars assess the validity, originality, and clarify of a manuscript before publication. In the best case, peer review improves, validates, and establishes quality and credibility in the scholarly record.
Reviewers typically assess a manuscript for:
Type | Who Sees What | Pros | Cons |
---|---|---|---|
Single-Blind | Reviewers know author identity; authors don't know reviewers' identities | Protects reviewers | May introduce bias |
Double-Blind | Reviewers' and authors' identities hidden | Reduces bias | Not always fully anonymous |
Open Review | Identities known to all; reviews sometimes published with the work | Transparency, accountability | Reviewers may be less candid |
Post-Publication | Peer review occurs after public release (e.g., preprints) | Speed, community feedback | Quality control can vary |
Single-blind and double-blind peer review processes are traditional forms of peer review and quite common.

Peer reviewers provide comments to an editor to help determine whether to publish a manuscript. Reviewers' comments typically align with one of these recommendations:
It is up to the editor(s) to consider the peer reviewers’ comments and recommendations, the author's response, and make a final decision. Some works go through several rounds of peer review and revision before acceptance or rejection.
It is also common for journals to accept categories of content that are not peer-reviewed but are reviewed in a different way. For example, a journal may accept opinion pieces, reflections, or commentary that do not undergo peer review but instead are reviewed solely by the editor. Author guidelines should explicitly describe the review process, whether peer, editorial, or something else, for each content category.
Consider that Peer Review Should Be a Dance, Not a Duel.
