LLMs struggle with confident fabrication in pain detection tasks

A new study evaluated six large language models on their ability to distinguish between actual pain signals and fabricated ones in clinical speech transcripts. While most models correctly abstained from predicting pain when no explicit cues were present, Gemini 2.5 Flash and Llama 3.1 8B demonstrated a tendency to confidently fabricate pain scores. The research highlights that models can be influenced by prompt framing, affecting their abstention rates, and that transcript-based predictions alone are insufficient for accurate pain assessment in such scenarios.

    Refusal Is Not Robustness: Auditing Confident Fabrication in Large Language Models on a Provably Uninformative Clinical Pain Speech Transcript

    arXiv:2608.26167v1 Announce Type: new Abstract: Hallucination and abstention benchmarks rarely establish that a model could not have known the correct answer, making it difficult to distinguish appropriate abstention from an unsupported prediction. Seven large language models wer…
