by justina


In episode three Predictions of The Code, Marcus du Sautoy explains how the wisdom of the crowd works: for one individual it is impossible to guess number of candies in the jar.  But when you calculate all guesses of the crowd and divide the sum from the number of responders you will get exactly the number of candies in jar. The group knows more than the individual. Incredible and even hard to believe.
