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

arXiv:2604.20443v2 Announce Type: replace-cross Abstract: We introduce DialToM, an annotated Theory of Mind (ToM) benchmark built from naturalistic human-human dialogues using a multiple-choice evaluation framework. Concurrent with recent work showing a gap between explicit mental-state inference and applied ToM in synthetic settings~\cite{gu2024simpletom}, we establish a stricter \emph{State-Driven Diagnostic Probe} in which models must forecast state-consistent dialogue trajectories solely from isolated mental-state profiles without dialogue context. Our evaluation reveals a systematic reaso

Why this matters
Why now

The continuous advancements in AI research necessitate more sophisticated benchmarks to accurately assess model capabilities, especially in complex human-like reasoning tasks.

Why it’s important

This benchmark addresses a critical gap in evaluating AI's understanding of mental states, which is fundamental for developing truly intelligent and context-aware autonomous agents.

What changes

The introduction of DialToM provides a more rigorous diagnostic tool for assessing 'Theory of Mind' in AI, potentially accelerating development in human-AI interaction and agentic systems.

Winners
  • · AI researchers
  • · AI ethics and safety organizations
  • · Developers of AI agents
Losers
  • · AI models with superficial ToM capabilities
  • · Benchmarks that rely solely on explicit inference
Second-order effects
Direct

Refinement of AI models specifically to address the challenges posed by the DialToM benchmark.

Second

Accelerated development of more robust, state-aware AI agents capable of nuanced human interaction.

Third

Enhanced trust and broader adoption of AI agents in complex decision-making and collaborative environments due to improved 'Theory of Mind'.
