A new arXiv paper proposes an evaluation framework for LLMs used as social simulators, arguing that matching final outcomes is insufficient — simulators must also replicate the underlying rationale-derived reasoning paths. Using a 94-person sunscreen concept test, the authors map open-ended human rationales into signed 'reason states' and show that LLM-simulated reasons, while superficially plausible, frequently mirror the stimulus material rather than recovering the respondent's actual acceptance or rejection logic. The framework provides an interpretable audit for whether LLM social simulators are reasoning correctly, not just producing correct-looking outputs.
