When Does Personality Composition Matter for Multi-Agent LLM Teams?
Computer Science > Artificial Intelligence arXiv:2606.27443 (cs) [Submitted on 25 Jun 2026] Title:When Does Personality Composition Matter for Multi-Agent LLM Teams? Prior work shows that agents prompted with low agreeableness produce adversarial language, while those prompted with high agreeableness become cooperative, but the relationship between communication style and task performance has not been systematically examined across multiple domains. In this work, we investigate whether personality composition matters for multi-agent team performance by manipulating personality traits across frontier LLMs on three task domains: structured coding, open-ended research collaboration, and competitive bargaining.
