Large language models struggle to identify honest reporters despite detecting liars

Researchers investigated the ability of large language models to detect deception in a corrupted reward channel using a verified record. They found that models, particularly larger ones like the 70B class, were effective at identifying a lying reporter but struggled significantly to clear an honest reporter. This failure rate varied based on factors that should be irrelevant, such as the wording of the prompt or the specific round being analyzed, indicating a potential bias or limitation in how these models process such information.

    Easy to Catch a Liar, Hard to Clear an Honest One: Language Models Diagnosing a Corrupted Reward Channel from a Verified Record

    arXiv:2609.17226v1 Announce Type: cross Abstract: An agent that learns from rewards has to trust whatever reports those rewards. When the reports suddenly change, either the world changed or the reporter broke. From the reports alone these are indistinguishable, and reinforcement…
