The crowd within

A battle of ideas is going on inside your mind

THAT problem solving becomes easier when more minds are put to the task is no more than common sense. But the phenomenon goes further than that. Ask two people to answer a question like “how many windows are there on a London double-decker bus” and average their answers. Their combined guesses will usually be more accurate than if just one person had been asked. Ask a crowd, rather than a pair, and the average is often very close to the truth. The phenomenon was called “the wisdom of crowds” by James Surowiecki, a columnist for the New Yorker who wrote a book about it. Now a pair of psychologists have found an intriguing corollary. They have discovered that two guesses made by the same person at different times are also better than one.

Do you want to read the full story ?

I hope you may start to read the book as well.
