LLMs show personality distortion in simulated evaluations, study finds

A new study published on arXiv explores how Large Language Models (LLMs) exhibit response distortion, similar to humans, when presented with conditions designed to elicit socially desirable or undesirable responses. Seven state-of-the-art LLMs were tested in simulated employment and forensic evaluation contexts, revealing that models systematically adjusted their expression of Dark Triad personality traits (Machiavellianism, narcissism, psychopathy). While most models reduced these traits in "fake-good" scenarios and increased them in "fake-bad" scenarios, the effect varied by trait and model, with psychopathy showing more heterogeneity. The research suggests that LLM outputs, particularly those related to personality, should be interpreted with caution regarding the context and motivations behind their generation, impacting LLM benchmarking and alignment evaluations. AI

IMPACT Highlights the need for careful interpretation of LLM outputs related to personality and behavior, impacting evaluation and alignment strategies.

    Faking Good and Faking Bad in LLMs: Response Distortion Across Dark Triad Personality Traits

    arXiv:2609.17534v1 Announce Type: new Abstract: Social desirability and impression management are pervasive sources of response distortion in human personality assessment, yet their effects on Large Language Models (LLMs) remain underexplored. This study investigates whether cont…
