The Tipping Point

by Malcolm Gladwell


Social change behaves like a contagion: it builds invisibly until a threshold is crossed, after which a small additional push produces a disproportionate cascade rather than a proportionate result.

What it teaches


Gladwell's organising claim is that ideas, products and behaviours obey epidemic logic, which means their growth is non-linear and their turning points are sharp. He proposes three mechanisms. The law of the few holds that a handful of unusual people carry most of the transmission — connectors who know an improbable number of people across social worlds, mavens who accumulate and volunteer information, and salesmen who persuade. The stickiness factor concerns the message itself: small changes in presentation can be the difference between something forgotten and something retained. The power of context argues that behaviour is far more sensitive to environment than to character, illustrated through the contested claim that repairing broken windows and graffiti reduced serious crime. He also popularised the ceiling on cohesive group size, roughly a hundred and fifty, above which organisations need formal structure to hold together. Parts of the social science have been challenged since 2000, and the book is best read as a vocabulary for thinking about thresholds and diffusion rather than as settled fact.
