The Comparator in Clinical AI

This article critiques a 2026 Science paper by Brodeur et al. comparing AI (OpenAI's o1) against unaided physicians, arguing the comparator is outdated as most physicians now use AI. It highlights the buried finding that physicians using GPT-4 barely outperformed those without, suggesting the human-AI combination may underperform AI alone. The author questions the validity of clinical vignette benchmarks and calls for research on real-world human-AI collaboration and new failure modes.

Key points

  • The study compares AI against unaided physicians, but in 2026 most physicians use AI, making the comparison irrelevant.
  • A buried finding shows physicians using GPT-4 did not significantly outperform those without, and AI alone often performed better.
  • Clinical vignettes fail to capture the messy, upstream work of real clinical practice.
  • The field should shift focus to studying human-AI collaboration, including overreliance and skill degradation.
