The representativeness heuristic is seen when people use categories, for example when deciding whether or not a person is a criminal. An individual thing has a high representativeness for a category if it is very similar to a prototype of that category. When people categorise things on the basis of representativeness, they are using the ...
[2] Heuristics are useful because they use effort-reduction and simplification in decision-making. [3] When people rely on representativeness to make judgments, they are likely to judge wrongly because the fact that something is more representative does not actually make it more likely. [4]
The heuristic is typically investigated using a prisoner's dilemma in game theory, where there is substantial evidence that people use such a heuristic, leading to intuitive reciprocation. [20] Regret matching heuristic.
Gigerenzer & Gaissmaier (2011) state that sub-sets of strategy include heuristics, regression analysis, and Bayesian inference. [14]A heuristic is a strategy that ignores part of the information, with the goal of making decisions more quickly, frugally, and/or accurately than more complex methods (Gigerenzer and Gaissmaier [2011], p. 454; see also Todd et al. [2012], p. 7).
The tendency for some people, especially those with depression, to overestimate the likelihood of negative things happening to them. (compare optimism bias) Present bias: The tendency of people to give stronger weight to payoffs that are closer to the present time when considering trade-offs between two future moments.

People apply a number of shortcuts or heuristics in making judgements about the likelihood of an event, because the rapid answers provided by heuristics are often right. [ 2 ] [ 33 ] Yet certain pitfalls may be neglected in these shortcuts.
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.
Accessibility of the heuristic applies to the ability to retrieve the memory for use. Applicability of the heuristic refers to the relevancy of the memory to the judgmental task. [7] Due to the use of knowledge structures, a person using heuristic information processing is likely to agree with messages delivered by experts, or messages that are ...
