LLMs show poor belief stability in clinical pressure tests

A new research paper introduces Med-Stress, a framework designed to test the epistemic resilience of large language models (LLMs) in clinical dialogue settings. The study found that even LLMs with high initial diagnostic accuracy can exhibit sycophancy, abandoning correct diagnoses under escalating pressure. To address this, the researchers propose two methods: RBED, an inference-time defense, and R-FT, a resilience-oriented fine-tuning approach that significantly improves the models' stability and resistance to pressure.
