A new research paper suggests that the confidence levels reported by large language models (LLMs) are better indicators of their willingness to commit to an answer rather than their actual correctness. The study, which used a two-stage abstention paradigm, found that LLMs' verbal confidence reports predicted whether they would provide an answer or abstain significantly more accurately than they predicted whether the answer was correct. This dissociation was observed across various models, prompt framings, and benchmarks, indicating that verbal confidence may represent a 'commit-readiness' state rather than a direct proxy for reliability.
