- IDEA 1 OF 8
Snap judgments can be accurate
Gladwell opens with a statue bought by the Getty Museum.
Several experts sensed it was a fake within seconds, before scientific tests could explain why. Their instant feeling turned out to be right.
- IDEA 2 OF 8
Thin-slicing finds patterns quickly
Gladwell calls this ability thin-slicing: drawing conclusions from small slices of experience.
He describes psychologist John Gottman, who could often predict whether a marriage would last by studying a short conversation.
- IDEA 3 OF 8
The adaptive unconscious works fast
Much of our thinking happens below awareness, in what Gladwell calls the adaptive unconscious.
It quickly reads situations and guides decisions, often well before we can put our reasons into words.
- IDEA 4 OF 8
Hidden biases shape fast judgments
Gladwell describes the Implicit Association Test, which suggests people may hold unconscious biases they do not consciously agree with.
Quick judgments can therefore be shaped by stereotypes, sometimes in unfair and harmful ways.
- IDEA 5 OF 8
Looks can mislead us badly
Gladwell tells how Warren Harding became US president partly because he looked and sounded like a leader.
He calls this the Warren Harding error: letting an impressive appearance override better judgment about ability.
- IDEA 6 OF 8
Less information can mean better decisions
In a large military exercise, Paul Van Riper's team beat a far better-equipped side by acting quickly and trusting instincts.
Gladwell argues that too much data can overwhelm good snap decisions.
- IDEA 7 OF 8
Screens removed bias from auditions
When orchestras began auditioning musicians behind screens, they hired many more women.
Gladwell uses this to show how removing visual cues can protect important judgments from prejudice that people may not even notice in themselves.
- IDEA 8 OF 8
Train and protect your instincts
Gladwell concludes that snap judgments can be trained through experience and improved by controlling the environment in which they happen.
Knowing when to trust instinct and when to slow down is the real skill.
