A new study evaluated the use of AI models, specifically 47 generative LLMs and 14 decision models, as synthetic survey respondents. The research found that while some models, like MiniMax M3, could achieve a Psychometric Similarity Score (PSS) of 0.813, they did not consistently outperform simpler statistical baselines such as Gaussian copulas. Notably, newer model releases did not always perform better than older versions, and decision models struggled to replicate individual human response patterns and correlations, indicating a gap between generating plausible answers and creating psychometrically valid synthetic respondents.
