AI rationale training hurts disease prediction, study finds

A new research paper challenges the common assumption that supervised fine-tuning with synthetic rationale data improves language model performance on clinical prediction tasks. Experiments on Alzheimer's disease prediction found that this method consistently degraded performance compared to label-only fine-tuning, even when the rationales were medically accurate. The study suggests a conflict between narrative plausibility and discriminative optimization is the likely cause, urging caution in developing language models for high-stakes medical applications.
