When it comes to making predictions about the future, the average expert is about as accurate as a dart-throwing chimpanzee. This was the much-publicised conclusion of the largest and most comprehensive analysis of expert predictions ever undertaken, completed by Philip Tetlock in 2005 after almost twenty years' work. Not only was the average success rate of the experts roughly equivalent to that of someone making random guesses, but Tetlock discovered that the more 'pre-eminent' the experts were, the less accurate their predictions tended to be. Philip Tetlock and Dan Gardner show that our desire for meaningful predictions about the future is far from futile, however. Based on an ongoing, multi-million dollar 'forecasting tournament', the authors offer compelling evidence for ways in which we are able to improve our foresight and make more accurate predictions.
