What potential bias might affect the peer review process?

The influence of personal relationships on the peer review process is a significant concern because it can lead to favoritism or conflicts of interest. When reviewers have personal ties to the authors, either as colleagues, friends, or former collaborators, they might unconsciously allow their relationship to skew their evaluation of the work. This can result in an unfair assessment—either overly favorable or overly critical—based not on the quality of the research but rather on personal feelings or biases.

This issue is especially pertinent in fields where collaborative networks are common, potentially affecting the integrity of the review process. Such biases can undermine the objective standards expected in peer review, which ideally should be a fair and impartial evaluation of scholarly work. As a result, it is crucial for the peer review process to have safeguards in place, such as declaring conflicts of interest, to minimize the impact of personal relationships on the review outcome.
