A new study published on arXiv reveals that large language models (LLMs) struggle with updating their clinical judgments as new patient evidence emerges. Researchers found that LLMs often increased prediction errors when evidence evolved, showing an asymmetry in how they responded to worsening versus improving evidence. The models also demonstrated a significant shift in estimates when prior risk increased, indicating a causal influence of their own prior beliefs. Prompting did not resolve these issues, and a new evaluation method called Evidence-Validated Longitudinal Update (EVLU) highlighted a trade-off between reliability and coverage in LLM performance.
