LLM realism not reliable for social science treatment effect accuracy

A new research paper challenges the common practice of using statistical realism as a proxy for evaluating Large Language Models (LLMs) in social science experiments. The study found a weak correlation between statistical realism and treatment-effect accuracy across multiple cross-national experiments. Optimizing for statistical realism can even decrease treatment-effect accuracy, particularly for behavioral outcomes where models may extrapolate from attitudinal patterns. The authors propose a diagnostic framework for LLM-generated synthetic data, emphasizing that simulated responses and treatment effects are distinct estimation targets. AI

IMPACT Challenges the reliability of LLM simulations for social science research, suggesting a need for more robust validation methods.
