Gambler's Fallacy

Definition 1

The term gambler’s fallacy refers to the mistaken belief held by some people that independent events are interrelated. For example, a roulette or lottery player may not choose to bet on a number that came up in the previous round. Even though people are usually aware that successive draws of numbers are unrelated, their gut feeling may tell them otherwise (Rogers, 1998).
