About this book
You trust a quick impression, and it feels solid before you have time to check it. Then a random number, a vivid memory, or a neat story nudges your judgment farther than you notice. The unsettling part is that the mind can feel most certain when it is least reliable.
What you'll learn
- You’ll spot when a quick impression is doing the work of evidence, so you can pause before you accept the first answer that feels right.
- You’ll recognize common judgment traps like anchoring, availability, and representativeness, so you can check whether a number or story is steering you too far.
- You’ll use base rates, sample size, and the outside view to make forecasts that are less vulnerable to confidence and coincidence.
- You’ll separate immediate experience from later memory, so you can judge choices by what they actually felt like instead of the story they left behind.
Themes
- Two systems
- Heuristics
- Overconfidence
- Prospect theory
