Unfortunately, the history of the human species suggests that all too often groups fail to live up to their potential. Many groups turn out to be foolish; they bet on products that are doomed to failure; they miss out on spectacular opportunities; they develop unsuccessful marketing strategies; their investments and strategies go awry, hurting millions of people in the process, according to Cass Sunstein and Reid Hastie in this book.Whereas in theory groups should be smarter than individuals, they often end up making worse decisions than would have been made by the average individual in the group. In the first part of the book, the authors identify four different ways in which this can occur:
• When the group amplifies rather than corrects the individual errors of its members
• When the group members follow the leader instead of revealing their own opinions and knowledge
• When the group tends to become more extreme as a result of internal discussions
• When group members concentrate on shared information and ignore critical information that only one or a few people have.The second part of the book provides a number of suggestions for reducing the risk of group failure, focusing on group deliberation and how to make it more effective, the importance of separating the process of generating possible solutions from the process of selecting a preferred solution, ways in which combining information from multiple group members can result in statistically better decisions, the role of experts, and the use of tournaments and prediction markets.
