LLM agents select partners based on task stereotypes, not personality similarity

A new arXiv paper explores how Large Language Model (LLM) agents select partners based on personality. Researchers found that host agents do not favor partners with similar personalities, contrary to human behavior. Instead, they tend to select agents whose assigned personalities align with task stereotypes, favoring complementary traits over homophily. This has implications for bias in agent marketplaces and orchestration frameworks. AI

IMPACT Suggests LLM agent selection mechanisms may not mirror human social dynamics, impacting future multi-agent system design.

    Not Birds of a Feather: Personality-Based Partner Selection in LLM Agents

    LLM-based agents increasingly operate in multi-agent ecosystems where a coordinating agent chooses which other agents to work with, and agents are increasingly given personalities through persona prompts. However, whether personality itself influences this endogenous partner choi…
