Main Idea

In The Wisdom of Crowds, Surowiecki challenges the conventional belief that experts or elite groups always make the best decisions. He posits that under the right conditions, large groups of ordinary people can make better decisions than even the most skilled individuals. The book explores how crowds, when diverse, independent, and decentralized, can aggregate information and insights to reach surprisingly accurate conclusions. Surowiecki examines this phenomenon across various domains, from economics and business to everyday life and politics, providing a compelling argument for the power of collective intelligence.

Collective Intelligence

Surowiecki introduces the concept of collective intelligence by recounting the story of British scientist Francis Galton, who observed a weight-judging contest at a livestock fair. The average guess of the crowd, consisting of butchers, farmers, and non-experts, was remarkably accurate, being just one pound off the actual weight. This incident led Galton to conclude that "the collective intelligence of a diverse group can be superior to that of a single expert." Surowiecki expands on this by highlighting how groups, if properly structured, can tackle problems and make decisions that are surprisingly accurate. He emphasizes three key elements necessary for a crowd to be "wise": diversity of opinion, independence, and decentralization.
