Experts most frequently decline peer review invitations when the topic falls outside their expertise, with over half indicating they do this "Frequently" or "Sometimes." Time constraints represent the second most common reason, with many experts citing this as a "Frequently" occurring issue.

Journal quality concerns show significant division among respondents - many experts "Frequently" decline reviews for lower quality journals, while others rarely consider this factor. Similarly, having too many existing review commitments is a common but not universal concern.

Conflicts of interest and paper quality concerns are less frequently cited as reasons for declining reviews. Most experts report these issues arise only "Rarely" or "Sometimes," with many indicating they "Never" decline for these reasons.

Several experts mentioned additional reasons in their comments, including poor English in manuscripts, preference for reviewing only in specific journals where they publish, and concerns about reviewing without compensation for commercial publishers.

     Reviewers may decline invitations for several reasons, such as lack of time, conflicts of interest, or insufficient expertise on the subject matter. For example, a reviewer might not have enough time to thoroughly assess a manuscript due to personal or professional commitments. They might also decline if they have a conflict of interest, such as a personal relationship with the authors or financial ties to a competing organization. In some cases, a reviewer might feel that the manuscript is outside their area of expertise, and they may not feel qualified to provide a meaningful evaluation.

However I am still doing it for free, when the review requests come from journals published by some scientific society.

    I completed my last peer review within the past week and maintain an active review volume of more than 20 per year. I carefully select invitations that align with my expertise, and while I receive many requests annually, I accept those where I can offer meaningful, well-considered feedback—usually dedicating 4–8 hours to each review. I only occasionally decline invitations, primarily due to time constraints or if the topic falls outside my core areas of expertise, ensuring that every review I undertake is both thorough and valuable.

    I decline a peer review invitation when I have too many other review commitments, time constraints due to personal or professional obligations, or if the manuscript falls outside my area of expertise. Additionally, I may decline if I identify a conflict of interest that could compromise the integrity of the review process or if the manuscript lacks fundamental scientific rigor and requires extensive revisions before a fair evaluation can be conducted.
