In this book, New Yorker columnist Surowiecki explores a deceptively simple idea that has profound implications: large groups of people are smarter than an elite few, no matter how brilliant--better at solving problems, fostering innovation, coming to wise decisions, even predicting the future. With seemingly boundless erudition and in clear, entertaining prose, Surowiecki ranges across fields as diverse as popular culture, psychology, ant biology, economic behaviorism, artificial intelligence, military history and political theory to show just how this principle offers important lessons for how e live our lives, select our leaders, run our companies, and think about our world.--From publisher description.
