Availability heuristic: a strategy in which judgement is based on how easily and how quickly you can come up with relevant examples. This strategy works because events that are frequent in the world are likely to be more available in memory. This strategy can lead to error because many factors other than frequency in the world can influence availability from memory (ex. Representativeness heuristic: a strategy used in making judgements about categories. This strategy is broadly equivalent to making the assumption that in general, the instances of each category will resemble the prototype for that category, and likewise the prototype resembles each instance.
