A new study published on arXiv challenges the effectiveness of supervised fine-tuning with synthetic rationale data for clinical prediction tasks. Researchers found that this method consistently degrades performance in predicting Alzheimer's disease and related dementias, even when the generated rationales are medically accurate. The study suggests a conflict between narrative plausibility and discriminative optimization is the root cause, urging a more precise understanding of rationale-based supervision for high-stakes applications.
