Zliobaité I, Fortelius M. Peer review: revise rules on conflicts of interest. Nature 2016;539(7628):168
According to the authors, definitions of conflicts of interest (COI) in peer review need to be reassessed to reflect modern research practices. This could markedly increase the speed and quality of peer review. For example, many potential reviewers are disqualified under current rules on co-authorship. Co-authors typically have a sound understanding of each other's work and provide frank and constructive feedback. Using them as reviewers avoids settling for candidates who may be too far removed from the topic or not sufficiently senior in the field.
