A new study published on arXiv, titled "Preferred, Not Safer: Pairwise Preference Is a Poor Proxy for Clinical Safety," investigates the reliability of clinician pairwise preferences in evaluating the clinical safety of large language models (LLMs). The research, which analyzed over 26,000 judgments from more than 736 clinicians, found that models highly ranked by preference often still exhibit significant clinically unsafe or misleading content. These safety failures are not uniform across medical specialties and can be masked by aggregate rankings. The study suggests that evaluation practices should distinguish between preference and safety, report safety-critical failure rates directly, and incorporate clinically adjusted rankings for LLMs used in medical decision-making.
