experts vs dart-throwing chimps, and the amateurs who beat both

Tetlock tracked tens of thousands of predictions from experts over almost two decades. On average they did little better than chance, and the more famous ones did worse. Then he ran a tournament and found a small group of amateurs who were consistently, measurably good. Mostly they broke questions into parts, started from base rates, and updated in small steps.
