A new paper explores the 'butterfly effect' in Large Language Model (LLM) social simulations, where small changes in implementation can lead to significant shifts in collective outcomes. Researchers found that altering persona representations in a repeated prisoner's dilemma game caused a 75.2 percentage point change in cooperation for GPT-5.2, demonstrating substantial model and perturbation sensitivity. The study also observed that these sensitivities can be amplified or attenuated through multi-agent interactions and can extend from individual agent behavior to network-level structures in social media simulations. To address these issues, the paper introduces TRAILS (Taxonomy for Robustness Audits In LLM Simulations) and the Social Simulation Audit Card as frameworks for systematically auditing these dependencies and ensuring the reliability of scientific claims derived from such simulations.
