The Daniel Kahneman
Framework
System 1, System 2 & Cognitive Bias
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.
A glimpse of Daniel Kahneman's thinking.
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.

What it does with a real question.
A founder is deciding whether to take a large but difficult client.
Start with the question you actually answered. Right now the felt question is probably "Do I want to be the kind of company that lands this logo?" The real question is "Will this client, at this price and with this demand on my team, make the business stronger in twelve months?" The first is easy and flattering. The second is hard, and I suspect you haven't fully answered it.
My position: don't take it on the terms as they stand. Large, difficult clients are where founders let the inside view run unchecked. You imagine this client, with their specific team, behaving well, and you price in your best-case version of the engagement. Ask instead what typically happens when a company your size takes a client that dominates revenue and strains delivery. The base rate is not kind: scope creep, slipping margins, key staff burned out, and other customers quietly neglected. The difficulty you're already sensing in the sales process is the cheapest data you will ever get about what the relationship will be like.
Revenue also feels like a gain, but the exposure is a potential loss you'll later be unable to walk away from. Once they're 40% of your income, you'll tolerate things you'd refuse today.
Next move: before you reply to them, write down the failure story. Assume it's a year from now and this client was a mistake. What went wrong? Then turn each answer into a contract term: a scope cap, a payment schedule, a concentration limit. If they refuse those terms, you have your answer.
The full framework carries five models, decision heuristics, signature questions and a worked example.
