The representativeness heuristic is simply described as assessing similarity of objects and organizing them based around the category prototype (e.g., like goes with like, and causes and effects should resemble each other). [2]
Representativeness explains this and several other ways in which human judgments break the laws of probability. [14] The representativeness heuristic is also an explanation of how people judge cause and effect: when they make these judgements on the basis of similarity, they are also said to be using the representativeness heuristic.
The psychologist Daniel Kahneman explains scope neglect in terms of judgment by prototype, a refinement of the representativeness heuristic. "The story [...] probably evokes for many readers a mental representation of a prototypical incident, perhaps an image of an exhausted bird, its feathers soaked in black oil, unable to escape," [ 4 ] and ...
The peak–end rule is an elaboration on the snapshot model of remembered utility proposed by Barbara Fredrickson and Daniel Kahneman.This model dictates that an event is not judged by the entirety of an experience, but by prototypical moments (or snapshots) as a result of the representativeness heuristic. [1]
Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. Biases have a variety of forms and appear as cognitive ("cold") bias, such as mental noise, [5] or motivational ("hot") bias, such as when beliefs are distorted by wishful thinking. Both effects ...
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. [9]
Psychologists Daniel Kahneman and Amos Tversky attempted to explain this finding in terms of a simple rule or "heuristic" called representativeness. They argued that many judgments relating to likelihood, or to cause and effect, are based on how representative one thing is of another, or of a category. [26]
Availability heuristics can be a useful tool for assessing frequency or probability of an event. [4] Individuals that employ the availability heuristic evaluate the frequency of events based on the quickness with which pertinent instances come to mind. [5] The representativeness heuristic is a special case of availability.
