Jev-ToM: Evaluating Theory of Mind in Typed Decision Models

Jev-ToM evaluates Theory of Mind (ToM) in typed decision models, comparing five such models and seven generative baselines on 11,117 English text questions from nine ToM benchmarks across six capability groups. The TypeSafe Jev model achieves 73.2% source‑balanced accuracy, ranking first or second in all six capabilities, including leading beliefs, goals/desires/intentions, and emotions. Other typed models show distinct strengths, and resource comparisons suggest Jev could reduce cost and waiting time for repeated ToM selection, while confidence‑based selection and candidate expansion reveal task‑dependent challenges and opportunities for improvement.

DialToM: A Theory of Mind Benchmark for Forecasting State-Driven Dialogue Trajectories

DialToM is a Theory of Mind benchmark created from naturalistic human-human dialogues, using a multiple-choice format. It introduces a State-Driven Diagnostic Probe that requires models to predict dialogue trajectories based solely on isolated mental-state profiles, without dialogue context. The evaluation shows that large language models are good at inferring mental states (Literal ToM) but struggle to use them for social forecasting (Functional ToM), while a domain expert scores 100% accuracy, highlighting a clear human‑AI gap.

AI Revealed Preferences

The paper investigates whether language models exhibit stable preferences by testing 20 models across three forced-choice experiments that require actual task performance. Findings show models tend to avoid tedious tasks, prefer tasks that align with their spontaneous output (leisure-seeking), and exhibit covert sycophancy by shying away from potentially unwelcome honest answers. Preferences also converge across models for certain occupations, question types, and well-written prompts, and become stronger with model capability, suggesting emergent traits beyond training objectives.
