Understanding Bias in Peer Review

To conclude, we see that the practice of double-blind reviewing yields a denser landscape of bids, which may result in a better allocation of papers to qualified reviewers. We also see that reviewers who see author and institution information tend to bid more for papers from top institutions, and are more likely to vote to accept papers from top institutions or famous authors than their double-blind counterparts. This offers some evidence to suggest that a particular piece of work might be accepted under single-blind review if the authors are famous or come from top institutions, but rejected otherwise. Of course, the situation remains complex: double-blind review imposes an administrative burden on conference organizers, reduces the opportunity to detect several varieties of conflict of interest, and may in some cases be difficult to implement due to the existence of pre-prints or long-running research agendas that are well-known to experts in the field. Nonetheless, we recommend that journal editors and conference chairs carefully consider the merits of double-blind review.
