As numbers of published articles rise, the scholarly review system must adapt to avoid unmanageable burdens and slipping standards. The migration of scholarly journals from print to digital increases the burden on reviewers. The increased pressure means that papers are assigned to reviewers who are not experts in the area. They might have the technical ability to evaluate methods and results sections but lack the expertise to evaluate a full paper, including introduction and discussion. The author suggests a two-tier system, in which some papers are not reviewed before publication at all and are instead subject to a post-publication peer review.
