There are 3 things you should know about the availability heuristic: Show
*** There are two biases emanating from the availability heuristic (a.k.a. the availability bias): Ease of recall and retrievability. Because of the availability bias, our perceptions of risk may be in error and we might worry about the wrong risks. This can have disastrous impacts. Ease of recall suggests that if something is more easily recalled in memory it must occur with a higher probability. The availability heuristic distorts our understanding of real risks.
When we make decisions we tend to be swayed by what we remember. What we remember is influenced by many things including beliefs, expectations, emotions, and feelings as well as things like frequency of exposure. Media coverage (e.g., Internet, radio, television) makes a big difference. When rare events occur they become very visible to us as they receive heavy coverage by the media. This means we are more likely to recall it, especially in the immediate aftermath of the event. However, recalling an event and estimating its real probability are two different things. If you’re in a car accident, for example, you are likely to rate the odds of getting into another car accident much higher than base rates would indicate. Retrievability suggests that we are biased in assessments of frequency in part because of our memory structure limitations and our search mechanisms. It’s the way we remember that matters. The retrievability and ease of recall biases indicate that the availability bias can substantially and unconsciously influence our judgment. We too easily assume that our recollections are representative and true and discount events that are outside of our immediate memory. *** In Thinking Fast and Slow, Kahneman writes:

Bazerman adds:
Robyn M. Dawes, in his book Everyday Irrationality, says:
* * * Retrievability (based on memory structures) We are better at retrieving words from memory using the word’s initial letter than a random position like 3 (Tversky & Kahneman, 1973). In 1984 Tverksy and Kahneman demonstrated the retrievability bias again when they asked participants in their study to estimate the frequency of seven-letter words that had the letter “n” in the sixth position. Their participants estimated such words to be less common than seven letter words ending in the more memorable “ing”. This response is incorrect. All seven letter words ending with “ing” also have an “n” in the sixth position. However, it’s easy to recall seven letter words ending with ing. As we demonstrated with Dawes above, this is another example of the conjunction fallacy. Retail locations are chosen based on search as well, which explains why gas stations and retail stores are often “clumped” together. Consumers learn the location of a product and organize their mind accordingly. While you may not remember the name of all three gas stations on the same corner, your mind tells you that is where to go to find gas. Each station, assuming all else equal, then has a 1/3 shot at your business which is much better than gas stations you don’t visit because their location doesn’t resonate with your minds search. In order to maximize traffic stores must find locations that consumers associate with a product. * * * Exposure Effect People tend to develop a preference for things because they are familiar with them. This is called the exposure effect. According to Titchener (1910) the exposure effect leads people to experience a “glow or warmth, a sense of ownership, a feeling of intimacy.” The exposure effect applies only to things that are perceived as neutral to positive. If you are repeatedly exposed to something perceived as a negative stimuli it may in fact amplify negative feelings. For example, when someone is playing loud music you tend to have a lot of patience at first. However, as time goes on you get increasingly aggravated as your exposure to the stimuli increases. The more we are exposed to something the easier it is to recall in our minds. The exposure effect influences us in many ways. Think about brands, stocks, songs, companies, and even the old saying “the devil you know.” * * * The Von Restorff Effect “One of these things doesn’t belong,” can accurately summarize the Von Restorff Effect (also known as the isolation effect and novelty effect). In our minds, things that stand out are more likely to be remembered and recalled because we give increased attention to distinctive items in a set. For example, if I asked you to remember the following sequence of characters “RTASDT9RTGS” I suspect the most common character remembered would be the “9” because it stands out and thus your mind gives it more attention. The Von Restorff Effect leads us to Vivid evidence. * * * Vivid Evidence According to William James in the Principles of Psychology:

An example from Freeman Dyson:
Availability Bias is a Mental Model in the Farnam Street Mental Model Index What is it called when a person estimates the likelihood of events based on how easily examples come to mind?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.
Which cognitive heuristic involves estimating the likelihood of a given outcome based on how easy it is to imagine that outcome quizlet?What is the availability heuristic? Estimating the frequency or likelihood of events based on how easily examples of the event come to mind.
What are the 4 types of heuristics?Each type of heuristic is used for the purpose of reducing the mental effort needed to make a decision, but they occur in different contexts.. Availability heuristic. ... . Representativeness heuristic. ... . Anchoring and adjustment heuristic. ... . Quick and easy.. What is an example of availability heuristic?The availability heuristic works by prioritizing infrequent events based on recency and vividness. For example, plane crashes can make people afraid of flying. However, the likelihood of dying in a car accident is far higher than dying as a passenger on an airplane.
