Out of One, Many: Using Language Models to Simulate Human Samples
Argyle et al., Princeton & Stanford
LLMs conditioned on sociodemographic backstories reliably mirror the complex belief structures of U.S. political subgroups — establishing the empirical foundation for synthetic population simulation.
Nature Computational Science · 2025
Automated Social Science: LLMs as Social Simulacra
Cui et al.
156 psychology and management experiments replicated using LLM agents. Main effects held in the majority of cases — the largest validation of LLM-as-participant methodology to date.
