Blink

Blink explores the power and pitfalls of rapid cognition — the snap judgments we make in the first two seconds of encountering something new. Gladwell argues that these instant decisions are often remarkably accurate (an art expert who spots a fake in seconds that fooled scientists for months) but can also be dangerously biased (police officers who shoot unarmed people because of unconscious racial associations).

The book's core insight for business is that expertise creates a form of intuition that is genuinely valuable, but only in domains where you have deep experience and the feedback loops are reliable. In unfamiliar territory, your snap judgments are just dressed-up prejudices. Learning to distinguish between genuine expert intuition and overconfident bias is one of the most important skills in decision-making.
