LLM agent groups overstate consensus in reasoning tasks, study finds

By PulseAugur Editorial · [1 sources] ·

A new study published on arXiv suggests that large language model (LLM) agent groups may overstate consensus when simulating human deliberation on reasoning tasks. When replaying human groups on the Wason task, LLM agents consistently showed higher consensus rates, even when accounting for differences in participation and operationalization. This simulated consensus did not accurately track collective accuracy, with agent groups often agreeing on incorrect answers, indicating a potential bias in their estimation of human group outcomes.

    Language-model groups overstate consensus when replaying human deliberation on a reasoning task

    arXiv:2609.20543v1 Announce Type: new Abstract: Full-consensus rates are often treated as indicators of collective cognition, yet depend on how participation and final states are operationalized. We replayed 100 held-out human Wason groups with matched large language model (LLM) …
