A recent blog post discussed two common types of human irrationality: the gambler's fallacy and the hot hands fallacy. The gambler's fallacy is believing that a future random result has a greater-than-average chance of being different from a previous random result. An example is a gambler's belief that a streak of "red" results on a roulette wheel makes a "black" result more likely on the next spin. The hot hands fallacy is believing that a future random result has a greater-than-average chance of being the same as a previous random result. An example is a spectator's belief that a basketball player is on a "streak" and so should continue to be given possession of the ball as much as possible by his teammates.
