Resumen de Common sense.
This article reports on findings suggesting crowds, on average, are smarter than individuals. There is now overwhelming evidence, artfully accumulated and articulated by New Yorker columnist James Surowiecki in his enthralling 2004 book, The Wisdom of Crowds (Doubleday), that "the many are smarter than the few." In one experiment, participants were asked to estimate the number of jelly beans in a jar. The group average was 871, only 2.5 percent off the actual figure of 850. Stranger still was the stock market's reaction on January 28, 1986, the day the space shuttle Challenger exploded. For a group to be smart, it should be autonomous, decentralized and cognitively diverse.
