How does the wisdom of the group make the smartest decision?

Introduction to group wisdom: How to make the smartest decision: Most of us, whether voters or investors, customers or managers, seem to think that valuable knowledge is in the hands of a few people, and the decisions made by elites are smarter. Few people believe that "rabble" can do as well as experts. But James, the famous columnist of The New Yorker magazine? Sorowicki believes that we either underestimate the wisdom of the group or overestimate the role of elites or experts. For example, when the United States searched for the sunken nuclear submarine "Scorpio", the accuracy of orientation prediction made by the information-deficient public exceeded that of military experts; The Iowa electronic market accurately predicted Schwarzenegger's election as governor; The Hollywood Stock Exchange also relies on the wisdom of the group to predict the box office income of movies. This is an era of group wisdom, and the development of information industry and media industry makes the distance between them no longer far away. As long as we master the principle of stimulating group wisdom, we can live freely in this complex world. The wisdom of the group can make zara, a famous fashion manufacturer, always grasp the trend and make stock investment tend to be rational. Of course, teamwork can also tell you why there are traffic jams, why hotels favored by customers are not overcrowded, and what are the good ways to win the grand prize of the quiz show. The wisdom of the group can also tell us how to live, how to choose leaders, how to do business and how to think about this strange world.
