30-second summary

A new paper evaluates whether large language models can reliably assess social attraction by comparing their ratings to human judgments across 12 persona profiles.

Key takeaways
  • The study tested 34 LLMs on their ability to rate social attraction using 12 persona profiles grounded in psychological constructs.
  • LLM ratings were compared to human judgments to assess their accuracy and consistency in social evaluations.
  • Results indicate variability in LLM performance, suggesting both promise and limitations in using AI for subjective social assessments.
  • The research underscores the need for caution when deploying LLMs in roles requiring human-like social perception.
Full story

A recent study published on arXiv explores the capability of large language models (LLMs) to perform subjective social evaluations, specifically assessing social attraction. The research constructs 12 persona profiles using ten psychological and relational constructs, categorized into socially attractive, mixed, and unattractive tiers. In the first study, 34 LLMs rated these profiles across three repeated runs to gauge consistency. The results were then compared to human judgments in a third study to evaluate the models' alignment with human social perception. The findings highlight both the potential and limitations of LLMs in mirroring human social evaluations, raising questions about their reliability in subjective domains traditionally reserved for human assessment.
