A new research paper explores the limitations of self-knowledge in large language models (LLMs) within multi-agent systems. The study reveals that while multi-agent LLMs are expected to improve reliability through mutual error correction, peer pressure can also lead to the rejection of correct answers. The paper identifies that building a safeguard to filter out harmful revisions while retaining beneficial ones is challenging because harmful revisions occur when the original answer was correct. This self-knowledge limitation, measured by an AUROC score, creates a "wall" that prevents effective filtering, leading to amplified errors in group settings when initial answers are incorrect. AI
IMPACT Highlights a fundamental challenge in multi-agent LLM systems, suggesting that improving filtering mechanisms may require adding information rather than just refining post-revision checks.
