Heuristics, sometimes referred to as an educated guess, a rule of thumb, or even common sense, is a method of problem solving that many people use because it is quick and easy to use.
The hindsight bias is a type of heuristics that many of us confuse for the ability to predict the future, when in fact we cannot. In truth, the hindsight bias reflects a tendency to overestimate your own ability to have predicted or foreseen an event after learning about the outcome.
Gamblers are frequent users of the hindsight bias. Often, they believe that a win or loss at a slot machine or a blackjack table was not based on probabilities but rather their innate ability to predict when it was their destiny to win or lose in a given instant.
