Group intelligence refers to a process by which large numbers of people simultaneously converge upon the same point(s) of knowledge.
Social psychologists study group intelligence and related topics such as decentralized decision making and group wisdom, using demographic information to study the ramifications for long-term social change. Marketing and behavioral finance experts use similar research to forecast consumer behavior (e.g. buying patterns) for corporate strategic purposes.
The term group intelligence describes how, under the best circumstances, large numbers of people simultaneously converge upon the same point(s) of knowledge. The term is often interchanged with the terms collective intelligence, cointelligence, crowd wisdom, and herd mentality. It is also used in conjunction with early adopters to describe how buying decisions are made for consumer products and in the stock market.
James Surowiecki, in The Wisdom of Crowds, claims that, ironically, group intelligence requires independence of thought as well as superior judgment. Unlike herd behavior, group intelligence—like crowd wisdom—is a uniquely human phenomenon. And, unlike the terms herd behavior and herd mentality, group intelligence connotes more rational decision processes: based less upon emotional reactions and more upon knowledge and understanding.
The idea of a "group mind" or "mob behavior" was first put forward by 19th century French social psychologists Gabriel Tarde and Gustav Le Bon. Herd behavior in human societies has also been studied by Sigmund Freud and Wilfred Trotter, whose book Herd Instincts in Peace and War is a classic in the field of social psychology. Economist/Sociologist Thorstein Veblen's Theory of the Leisure Class illustrates how individuals imitate other group members of higher social status in their consumer behavior. Francis Galton, (1822-1911)a British Scientist who conducted anthropometric and psychometric studies on human behavior, is famous for his "ox" guesstimation study. Dr. Galton queried a crowd about the weight of an ox, and their guesses compiled and averaged were within one pound of its actual weight.
More recently, Malcolm Gladwell in The Tipping Point, examines how cultural, social, and economic factors converge to create trends in consumer behavior. James Surowiecki's The Wisdom of Crowds explains how group intelligence works—and doesn't work—to benefit mankind.
A popular example of group intelligence was the TV game show, "Who Wants to Be a Millionaire." Contestants were asked questions from history and popular culture, and when stumped, can query the audience. When audience members are polled for answers during the show, they are correct 91% of the time.
Twenty-first century academic fields such as marketing and behavioral finance draw upon group intelligence gathering data to identify and predict the rational and irrational behavior of investors. (See the work of Daniel Kahneman, Robert Shiller, and Amos Tversky.) Driven by emotional reactions such as greed and fear, investors can be seen to join in frenetic purchasing and sales of stocks, creating bubbles and crashes.
