Compared to the gambler's fallacy in which one makes predictions negatively dependent on the past information, in the hot hand belief, one makes predictions positively dependent on the past information. Both phenomena have been attributed to people's misperception of randomness. The present study examines an alternative explanation that the positive dependency in the hot hand belief may be due to people's effort to reduce uncertainty by estimating the unknown probability (common probability
