Closing the Loop to Discover Psychological Theories with an Automated Cognitive Scientist
Summary
The Automated Cognitive Scientist (AutoCog) is a fully autonomous agentic-AI system designed to automate theory-building in cognitive science, a process traditionally manual despite advancements in data collection and experiment design. AutoCog operates in a closed-loop discovery cycle where large-language-model agents propose competing theories as executable cognitive models, design experiments to discriminate them, collect behavioral data from online participants, and then score, diagnose, and synthesize improved successor theories. In the domain of decision-making, AutoCog successfully recovered known strategies from simulated behavior, including unconventional ones. When tested with human participants, it generated theories that outperformed established ones it was initially seeded with and demonstrated generalization to held-out studies across two experimental settings. Notably, AutoCog also discovered a novel theory of multi-cue decision-making, predicting diminishing sensitivity to feature values, which was subsequently confirmed in a preregistered study. This system was published on 2026-06-24.
Key takeaway
For AI Scientists and Research Scientists focused on cognitive modeling, AutoCog demonstrates a paradigm shift in theory development. You should consider integrating autonomous agentic-AI systems into your research workflows to accelerate the discovery and refinement of psychological theories. This approach allows for data-driven exploration of complex behavioral phenomena, potentially surfacing novel insights and outperforming established models, thereby making theory-building more explicit and cumulative.
Key insights
AutoCog automates cognitive theory discovery by iteratively proposing, testing, and refining executable psychological models using LLM agents.
Principles
