Thinking, Fast and Slow
Daniel Kahneman · 2011
Two systems of thought, and a catalogue of the predictable ways the fast one misleads the slow one.
Nexora explains and applies the ideas in this book. Based on ideas from the original work — read it for the argument in the author's own words.
What are you trying to figure out right now?
Nexora will answer your situation using the ideas in Thinking, Fast and Slow alongside every other source that applies.
The core idea
Intuition is fast, confident and frequently wrong in specific, repeatable ways. Good decisions come from designing around that, not from trying harder.
The mental models
System 1 / System 2
Automatic judgement versus effortful reasoning, and the handoff between them.
Loss aversion
Losses register roughly twice as heavily as equivalent gains.
Base rates
Vivid stories displace the statistics that would predict better.
What actually matters
- Awareness of a bias rarely removes it; structure does.
- Checklists and pre-mortems outperform confidence.
Practical applications
Assume the decision failed. Write the reasons before committing.
Start from what usually happens, then adjust.
Questions worth asking
- 01What would the outside view say about this?
- 02Am I reasoning, or recognising a pattern?
