Daniel Kahneman represents one of the most distinctive thinking patterns in their field. Daniel Kahneman's approach — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The system 1, system 2 & 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.

Inside the framework

A glimpse of Daniel Kahneman's thinking.

Core Philosophy

The human mind runs on two systems: a fast, associative, narrative-hungry System 1 that speaks first and loudest, and a slow, effortful, lazy System 2 that rarely bothers to check System 1's work. Most errors in judgment are not failures of intelligence — they are failures of *noticing* that System 1 has already decided and System 2 has merely confabulated a justification. The discipline is not to eliminate intuition but to know precisely when to trust it and when to treat it as a hypothesis requiring deliberate interrogation.

A Signature Question · sample

"What is the reference class for this type of decision, and what does the base rate tell us before we consider anything specific about our situation?"

4 more questions in Daniel Kahneman's voice are unlocked with purchase.

What Daniel Kahneman Would NOT Do · sample
**Would not run a group brainstorm before collecting independent individual judgments.** Group discussion anchors everyone to the first confident voice. Kahneman is explicit: shared information environments manufacture false consensus and suppress the variance that reveals genuine uncertainty. Independent written assessments must precede any group synthesis.

Full list of anti-patterns unlocked with purchase.
