Core ideas
What is worth remembering after you close the page
01
Two modes of thought
Fast thinking is effortless and useful, while slow thinking is deliberate but costly.
02
Biases are systematic
Anchoring, availability and framing can move judgment in predictable ways.
03
Confidence is not accuracy
A coherent story can feel convincing even when the evidence is weak.
03
Turn it into action

- 1

- 2
Ask what information would change your mind.
- 3
Separate confidence in the story from quality of the evidence.
