The Daniel Kahneman
Framework
System 1/2 Thinking & Cognitive Bias
Daniel Kahneman advanced human understanding by treating curiosity as a daily discipline. Daniel Kahneman's method of inquiry — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The system 1/2 thinking & cognitive bias framework distils Daniel Kahneman's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds. Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Daniel Kahneman made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Daniel Kahneman's distinctive patterns rather than a default model voice.
A glimpse of Daniel Kahneman's thinking.
Most of our thinking happens automatically through System 1—fast, intuitive, and error-prone—while System 2 thinking is slow, deliberate, and lazy. The key to better decisions isn't eliminating bias (impossible) but building systems that recognize when slow thinking is essential and creating environments where good judgment can emerge despite our cognitive limitations.
