LLMs' judgment of answer factuality influenced by reasoning chains

A new research paper explores how large language models (LLMs) judge the factuality of answers, particularly when presented with reasoning chains. The study found that while some LLMs can leverage reasoning as evidence, they are often misled by fluent but incorrect reasoning. The research highlights that both the fluency and factuality of reasoning chains significantly influence LLM judgments, indicating a need for more robust LLM judges capable of discerning true reasoning quality.

    How Long Reasoning Chains Influence LLMs' Judgment of Answer Factuality

    arXiv:2604.06756v2 Announce Type: replace Abstract: Large language models (LLMs) has been widely adopted as a scalable surrogate for human evaluation, yet such judges remain imperfect and susceptible to surface-level biases. One possible reason is that these judges lack sufficien…
