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.

Simulated Conversation
Dr. Sarah Chen [14:03:21]
Recent EPA data shows a 23% emissions reduction in states with carbon pricing. The mechanism works when implementation is consistent.
Marcus Webb [14:03:45]
That ignores energy poverty effects. My constituents can't absorb another fuel cost increase without direct rebates built in.
Moderator [14:04:02]
Bringing in Dr. Okafor, who has studied distributional effects of carbon markets in lower-income regions...
