New framework for decision theory proposed; functional decision theory critiqued

By PulseAugur Editorial · [3 sources] ·

A new paper proposes a formal framework for decision theory using nonparametric structural equation models (NPSEMs), aiming to provide a clearer modeling language and evaluative ground for the field. This approach introduces 'personal decision theory,' which guides agents to maximize their subjective counterfactual utility. The paper also suggests a performance metric for decision theories and analyzes classic problems like the smoking lesion and Newcomb's problem. Separately, a LessWrong post critiques functional decision theory (FDT), arguing it is underspecified and its recommendations are implausible, contrasting it with causal decision theory (CDT) and evidential decision theory (EDT). AI

IMPACT This research could refine AI agent decision-making frameworks, while critiques of existing theories highlight ongoing challenges in rational agent design.
