Maintaining trust in scholarly communication requires that peer reviewers treat manuscript material as confidential intellectual property and a privileged responsibility toward authors, editors, and the public. Failure to preserve confidentiality undermines the peer review system, can harm careers, and may lead to misuse of ideas or data.
Confidentiality as a professional duty
Guidance from the Committee on Publication Ethics emphasizes that reviewers must not share, cite, or use unpublished material from a manuscript before it appears in the public record. The International Committee of Medical Journal Editors similarly frames review as a confidential service to the journal and authors. Richard Smith former editor of The BMJ has discussed how breaches erode trust and damage the credibility of journals and researchers. Reviewers should therefore decline invitations when they cannot keep material confidential, when they have conflicts of interest, or when they require time or support they do not have.
Practical steps for ethical handling
Reviewers protect confidentiality by keeping manuscript files secure, avoiding discussion of content outside the editorial process, and not using unpublished methods, data, or ideas for their own work. When a review requires specialized input, reviewers should seek permission from the editor before consulting colleagues and must name any consultation in their report. If a reviewer suspects misconduct or potential harms—such as fabrication, ethical violations in human or environmental research, or possible breaches affecting Indigenous or territorial rights—they should report concerns to the editor rather than confronting authors directly.
Breach causes often include competitive pressure, lack of awareness of journal policies, or ambiguous norms in small research communities. Consequences range from retractions and damaged reputations to legal liability and loss of community trust, particularly where research affects vulnerable populations or sensitive ecological and territorial data. In fields with Indigenous knowledge or local environmental data, confidentiality has cultural and territorial dimensions that require extra care to avoid exploitation or unintended exposure.
When breaches occur, editors typically investigate following established protocols and may notify institutions. Reviewers found to have misused confidential information can be removed from reviewer databases and barred from future review, and journals may issue corrections or retractions to protect the scholarly record. Upholding integrity, transparency with editors, and respect for authors’ rights is central to ethical peer review and to sustaining a trustworthy scientific enterprise.
