Peer review is built on trust. Authors trust reviewers to evaluate their work fairly, journals trust reviewers to uphold standards, and the scientific community relies on reviewers to protect the integrity of published research. With this responsibility comes a strong ethical obligation.

Confidentiality

Reviewers must treat manuscripts as confidential documents. Sharing content, data, or ideas from a manuscript—before publication or without permission—is a serious ethical violation. Unpublished research should never be used for personal advantage.

Objectivity and Fairness

A reviewer’s role is to assess the quality, validity, and originality of research—not the author’s identity, institution, or personal viewpoints. Bias, whether conscious or unconscious, can compromise the peer review process. Ethical reviewers focus solely on the scientific merit of the work.

Conflict of Interest

Reviewers must disclose any potential conflicts of interest, such as personal relationships, financial interests, or direct competition with the author. If a conflict exists, declining the review is the most ethical choice.

Constructive Feedback

Ethical peer review is not about criticism alone. Reviewers should provide clear, respectful, and constructive feedback that helps authors improve their work. Dismissive or hostile language undermines the purpose of peer review.

Timeliness

Delays in peer review can hinder scientific progress. Ethical reviewers accept assignments only when they can complete them within the agreed timeframe.

By adhering to these principles, peer reviewers contribute to a transparent, credible, and trustworthy scholarly publishing system.
