  2. Availability heuristic - Wikipedia

    en.wikipedia.org/wiki/Availability_heuristic

    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. If someone sees both sharks and dolphins in the ocean, they will be less aware of seeing the dolphins, because the dolphins had less of an impact on their memory.

  3. Representativeness heuristic - Wikipedia

    For example, people have long believed that ulcers were caused by stress, due to the representativeness heuristic, when in fact bacteria cause ulcers. [2] In a similar line of thinking, in some alternative medicine beliefs patients have been encouraged to eat organ meat that corresponds to their medical disorder.

  4. List of cognitive biases - Wikipedia

    en.wikipedia.org/wiki/List_of_cognitive_biases

    The availability heuristic (also known as the availability bias) is the tendency to overestimate the likelihood of events with greater "availability" in memory, which can be influenced by how recent the memories are or how unusual or emotionally charged they may be. [20] The availability heuristic includes or involves the following:

  5. Heuristic (psychology) - Wikipedia

    en.wikipedia.org/wiki/Heuristic_(psychology)

    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 ...

  6. Exemplification theory - Wikipedia

    en.wikipedia.org/wiki/Exemplification_theory

    The representativeness heuristic is a special case of availability. It stipulates that abstract base-rate information plays little role in quantitative judgments about event populations. Instead, these judgments are based on the sample of more concrete exemplars that are available to the individual at the time of decision making.

  7. Gambler's fallacy - Wikipedia

    en.wikipedia.org/wiki/Gambler's_fallacy

    Amos Tversky and Daniel Kahneman first proposed that the gambler's fallacy is a cognitive bias produced by a psychological heuristic called the representativeness heuristic, which states that people evaluate the probability of a certain event by assessing how similar it is to events they have experienced before, and how similar the events ...

  8. Availability cascade - Wikipedia

    en.wikipedia.org/wiki/Availability_cascade

    The availability heuristic, first identified by Daniel Kahneman and Amos Tversky, is a mental shortcut that occurs when people judge the probability of events by how easy it is to think of examples. The availability heuristic operates on the notion that, "if you can think of it, it must be important."

  9. Hindsight bias - Wikipedia

    en.wikipedia.org/wiki/Hindsight_bias

    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.
