The availability heuristic, also known as availability bias, is a mental shortcut that relies on immediate examples that come to a given person's mind when evaluating a specific topic, concept, method, or decision.
In psychology, availability is the ease with which a particular idea can be brought to mind. When people estimate how likely or how frequent an event is on the basis of its availability, they are using the availability heuristic. [58] When an infrequent event can be brought easily and vividly to mind, this heuristic overestimates its likelihood.
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:
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."

This, along with the findings in Evolutionary psychology and Neuroscience above, suggests that our cognitive heuristics are at their best when operating in a social, political and economic environment most like that of the Paleolithic/Holocene. If this is true, then one possible means to achieve at least some cognitive bias mitigation is to ...
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]
The availability heuristic tells us that judgments of social phenomena are greatly influenced by the ease with which information comes to mind. [3] 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 ...
