Gary King's study: AI peer reviews beat paid human experts on every measure

A new paper by Gary King and Steven Worthington finds AI-generated article reviews outperform reviews from well-compensated human experts — judged unusually high quality by editors and authors — on every measure the authors could construct. AI reviews scored higher on all seven assessed dimensions, and three former journal editors preferred the AI reviews in 90% of cases.

The study compares AI reviews against 134 reports from carefully selected, paid human experts. Commentator Valerio Capraro flags huge upside (faster, higher-quality feedback; fully AI-run journals) but warns a few AI gatekeepers could narrow which ideas survive, especially at the scientific frontier where AI hallucination risk is highest — potentially embedding errors at the core of human knowledge.
