The wisdom of crowds and the miracle of aggregation, arguably, are the reasons why markets and democracy work as well as they do. As New Yorker James Surowiecki explains in his new book, "consider the show Who Wants to Be a Millionaire. When a contestant on the show is stumped by a question, he has a couple of choices in asking for help: the audience or someone he's designated as an expert. The experts do a reasonable job: They get the answer right 65% of the time. But the audience is close to perfect: It gets the answer right 91% of the time, even though it's made up of people who have nothing better to do than sit in a TV studio and watch Regis Philbin." The new, new tipping point?
