Expanded implementation of Fast & Fair paid peer review reduces time to first decision without reducing review quality in a biology journal

Traditional peer review is often slowed by delays in identifying willing reviewers and waiting for completed review reports. In a 2024 pilot on the journal Biology Open, we showed that Fast & Fair peer review, which uses pre-contracted paid reviewers and a structured editorial timeline, could deliver rapid, high-quality peer. Here, we report the expanded implementation of Fast & Fair at Biology Open in 2025. From 1 April 2025 onward, all direct submissions to the journal were considered for Fast & Fair peer review unless appropriate pre-contracted reviewer expertise was unavailable. Reviewers were paid 220 GBP per manuscript only if they completed the review on time, and the review met editorial quality expectations. Among peer-reviewed manuscripts submitted in 2025, Fast & Fair reduced time to first decision with reviews from a mean of 37.7 working days under conventional peer review to 5.5 working days. Reviewer commitment also improved. Fast & Fair invitations were accepted more often than conventional invitations (67% versus 23%), had lower nonresponse (13% versus 39%), and had higher completion among accepted invitations (98% versus 87%). Faster review was not associated with reduced review quality. Handling editors scored each review for usefulness in editorial decision-making. Fast & Fair produced fewer low-scoring reports than conventional peer review. Editorial behavior was also unchanged, with similar first-decision profiles and final acceptance rates (59% versus 61%). While financial sustainability remains to be tested at scale, the Fast & Fair model addresses a major bottleneck in traditional peer review by replacing ad hoc reviewer recruitment with conditional compensation, predefined quality standards and a strict editorial timeline.
