A growing body of literature has identified potential problems that can compromise the quality, fairness, and integrity of journal peer review, including inadequate review, inconsistent reviewer reports, reviewer biases, and ethical transgressions by reviewers. We examine the evidence concerning these problems and discuss proposed reforms, including double-blind and open review. Regardless of the outcome of additional research or attempts at reforming the system, it is clear that editors are the linchpin of peer review, since they make decisions that have a (...) significant impact on the process and its outcome. We consider some of the steps editors should take to promote quality, fairness and integrity in different stages of the peer review process and make some recommendations for editorial conduct and decision-making.
