arXiv:2606.01637v1 Announce Type: new Abstract: Large language models are increasingly used in multi-agent systems, where they see and respond to other agents' answers. A key risk is conformity: a model may abandon its own answer simply because others agree on a different one. Prior studies show that LLMs often revise toward a majority answer, but it remains unclear whether these revisions help correct mistakes as often as they introduce new errors. In this paper, we conduct a controlled study in which an LLM first answers a question, then sees simulated peer responses before making a final de
The proliferation of LLMs in multi-agent systems necessitates understanding their social dynamics, particularly conformity, as advanced AI applications move from theory to deployment.
This research provides critical insights into the reliability and vulnerability of AI agents within networked environments, impacting the design and trustworthiness of future AI systems.
Our understanding of LLM revision dynamics is updated, highlighting that group conformity can introduce errors more readily than it corrects them, challenging assumptions about collaborative AI improvement.

LLM-powered multi-agent systems become demonstrably less reliable in decision-making due to conformity bias.
New architectural patterns will emerge for multi-agent systems focusing on independent verification and bias mitigation, rather than purely consensus-driven approaches.
Public distrust in autonomous AI systems could increase, leading to stricter regulatory frameworks around AI transparency and accountability in collaborative tasks.
