Architecture & System Overview
Thinking, Fast and Slow Decision Quality Toolkit is an unofficial, independent system for making important decisions more explicit, testable, and reviewable.
It is designed for founders, product leaders, operators, investors, consultants, and teams who need to decide under uncertainty without confusing confidence with evidence.
The toolkit produces decision briefs, assumption registers, evidence audits, reference-class comparisons, pre-mortems, red-team challenges, reversible experiments, stopping rules, decision memos, and calibration reviews. It will not reproduce the book, its distinctive wording, diagrams, examples, or a chapter-by-chapter summary.
This is a decision-support system, not investment, legal, medical, or other regulated professional advice. High-impact decisions still require appropriate human and professional review.
The full 96-prompt system is available now as an instant digital download after purchase. This is an unofficial, independent work and is not affiliated with Daniel Kahneman, his representatives, or any publisher or rights holder.

Pre-mortems finally made our risk reviews useful
Our risk reviews used to be theater until we ran the pre-mortem module on a flagship launch — it generated failure modes the team was too committed to see, and the early-warning signals were specific enough to act on. The assumption register made the beliefs carrying the decision visible and testable. Risk review is now our most productive meeting.
Deep toolkit, work through it slowly
This is a deep toolkit — the evidence audits and red-team pass are serious, not surface-level. It rewarded working through it slowly, one module at a time, rather than trying to use everything at once. Four stars because the depth means a real time investment before you feel fluent.
Confidence vs evidence, made visible
I use this in investor and consultant work, and the calibration review made confidence versus evidence visible in a way I had never seen on a team. The reference-class comparisons killed a 'sure thing' that had no outside support. The decision memo format is now the standard for our high-stakes choices.
