What aspect of the peer review process may pose a conflict of interest?

The selection of reviewers based on study outcomes presents a potential conflict of interest because it might lead to biased assessments. If reviewers are chosen primarily based on whether they agree with or support the outcomes of the study, they may not provide an impartial evaluation of the research. This could compromise the integrity of the peer review process, as the review should be based on the quality and rigor of the methodology, data, and analysis rather than preconceived notions about what the study should conclude. A fair review process requires an objective evaluation, free from the influence of the outcomes that might favor certain perspectives or biases.

Other options, such as the anonymity of the submitted work and the institutional affiliations of the reviewers, do not inherently lead to a conflict of interest in the same direct manner. Anonymity is intended to protect reviewers and encourage honest feedback. Institutional affiliations can introduce biases, but they are generally considered when selecting an appropriate reviewer rather than being a direct cause of conflict in the review process itself. Previous publications by researchers may provide context for their expertise, but again, they do not create an immediate conflict unless there is a direct financial or personal interest involved.
