A heuristic device is used when an entity X exists to enable understanding of, or knowledge concerning, some other entity Y. A good example is a model that, as it is never identical with what it models, is a heuristic device to enable understanding of what it models. Stories, metaphors, etc., can also be termed heuristic in this sense.
In the early 70s, the investigation of heuristics and biases was a large area of study in psychology, led by Amos Tversky and Daniel Kahneman. [8] Two heuristics identified by Tversky and Kahneman were of immediate importance in the development of the hindsight bias; these were the availability heuristic and the representativeness heuristic .
For example, if there is a test for a disease which has an accuracy of 90%, people may think it's a 90% they have the disease even though the disease only affects 1 in 500 people. [ 46 ] Common sense heuristic: Used frequently by individuals when the potential outcomes of a decision appear obvious.

In psychology and cognitive science, a schema (pl.: schemata or schemas) describes a pattern of thought or behavior that organizes categories of information and the relationships among them. [ 1 ] [ 2 ] It can also be described as a mental structure of preconceived ideas, a framework representing some aspect of the world, or a system of ...
In psychology, a heuristic is an easy-to-compute procedure or rule of thumb that people use when forming beliefs, judgments or decisions. The familiarity heuristic was developed based on the discovery of the availability heuristic by psychologists Amos Tversky and Daniel Kahneman; it happens when the familiar is favored over novel places, people, or things.
Due to the availability heuristic, names that are more easily available are more likely to be recalled, and can thus alter judgments of probability. [31] Another example of the availability heuristic and exemplars would be seeing a shark in the ocean. Seeing a shark has a greater impact on an individual's memory than seeing a dolphin.
In psychology, a fluency heuristic is a mental heuristic in which, if one object is processed more fluently, faster, or more smoothly than another, the mind infers that this object has the higher value with respect to the question being considered. [1]
