Summary
Gladwell argues that change happens in non-linear bursts, governed by three rules: the Law of the Few (a small number of unusually-connected people drive most spread), the Stickiness Factor (the message has to be memorable in a specific way), and the Power of Context (small environmental changes massively shift behavior). The book pairs research with case studies — Hush Puppies, NYC crime decline, Sesame Street — to show how big change comes from small, well-targeted nudges.
