LLM personas drive polarization in social simulations, study finds

By PulseAugur Editorial · [1 sources] ·

A new research paper explores how personas constructed from large-language models (LLMs) influence polarization in generative social simulations. Researchers used a Twitter-like simulation with personas derived from the American National Elections Study (ANES) to test the impact of partisan identity layers. They found that the translation of survey responses into personas significantly affects collective outcomes, with the removal of explicitly partisan statements leading to more cross-party ties similar to real Twitter networks. The study suggests that the salience of issues, as translated into behavioral instructions by persona construction, plays a crucial role in simulation validity. AI

IMPACT This research highlights how LLM-driven personas can inadvertently amplify polarization in simulations, suggesting a need for more robust evaluation methods for agent-based modeling.

    From Caricature to Collective Artifact: How Persona Construction Drives Polarization in Generative Social Simulations

    arXiv:2610.16498v1 Announce Type: cross Abstract: Generative Social Simulation (GSS) leverages Large Language Models (LLMs) to create sophisticated personas that define agents with demographics, emotions, and political opinions. While prior work shows that personas compress outpu…
