New research questions Prospect Theory's reliability for LLM decision-making

A new research paper explores the applicability of Prospect Theory (PT) to Large Language Models (LLMs), revealing significant instabilities in their decision-making processes when faced with epistemic uncertainty. The study developed a workflow to estimate PT parameters for LLMs and found that PT does not consistently or reliably describe LLM behavior, particularly when uncertainty is expressed linguistically. The findings caution against using PT-based frameworks in real-world applications where ambiguity is common, suggesting a need for new alignment directions for LLM decision-making. AI

IMPACT Challenges the reliability of established behavioral economics frameworks for understanding and aligning LLM decision-making under uncertainty.

    Rethinking Prospect Theory for LLMs: Revealing the Instability of Decision-Making under Epistemic Uncertainty

    arXiv:2508.08992v4 Announce Type: replace Abstract: Real-world decision-making often involves uncertainty expressed in linguistic rather than numerical terms, and Prospect Theory (PT) provides a classic framework for modeling human behavior under such uncertainty. Although recent…
