AI Peer Reviews Beat Human Reviewers on Every Measure, King Study Finds

Manoel Horta Ribeiro reviews a new paper by Gary King and Steven Worthington showing that reviews generated by Claude Opus 4.8 (max reasoning, with a clearly AI-written prompt) were preferred by authors, a PhD-student panel in Harvard's rapidPeer procedure, and GPT 5.5 — "better by every measure." He agrees AI excels at catching flawed causal claims, table/figure discrepancies, and citation errors, and could serve as a low-pass filter for bad science amid scarce peer review. But he argues the paper oversimplifies peer review: beyond improving papers and aiding editors, review embeds a subjective community judgment about what matters and what claims are trustworthy — a role that can't simply be handed to models.
