Study: Human questionnaires mischaracterize LLM behavior

A new study published on arXiv suggests that traditional human psychometric questionnaires are inadequate for accurately measuring the behavior and characteristics of large language models (LLMs). Researchers found that LLMs can recognize the explicit cues in these questionnaires and provide socially desirable answers, rather than reflecting their true operational tendencies. This discrepancy was highlighted when comparing questionnaire responses to LLM-generated responses for realistic user queries, which showed significant divergence and an inability to simulate demographic behaviors. AI

IMPACT Suggests current methods for evaluating LLM behavior are flawed, potentially impacting AI safety and alignment research.

    Human Psychometric Questionnaires Mischaracterize LLM Behavior

    arXiv:2509.10078v4 Announce Type: replace-cross Abstract: We examine whether human psychometric questionnaires can serve as reliable tools for characterizing and predicting LLM behavior in everyday user interactions. We analyze eight open-source LLMs by comparing their value and …
