Representativeness heuristics defines several fallacies and cognitive biases that we encounter in day to day decision making. Availability heuristic provides us with the ability to quickly judge the likeliness of an event by the most outstanding memories we have associated with it.

The availability heuristic is a mental shortcut that relies on immediate examples that come to a given person's mind when evaluating a specific topic, concept, method or decision the availability heuristic operates on the notion that if something can be recalled, it must be important, or at least more important than alternative solutions which are not as readily recalled.
