Availability Heuristic Quotes & Sayings

Most people give substantial weight to anecdotal evidence, perhaps so much that it will cancel out positive recommendations found in consumer reports. People's tendency to give undue weight to some types of information is called the availability heuristic. A heuristic is a rule of thumb, a mental shortcut. Suppose someone asked you a question like what's more common in English, words that start with the letter to r words that have t as the third letter. You would have an easier time generating words that started with the letter t. Words starting with t would be more 'available'. — Barry Schwartz

The conclusion is that the ease with which instances come to mind is a System 1 heuristic, which is replaced by a focus on content when System 2 is more engaged. Multiple lines of evidence converge on the conclusion that people who let themselves be guided by System 1 are more strongly susceptible to availability biases than others who are in a state of higher vigilance. The following are some conditions in which people "go with the flow" and are affected more strongly by ease of retrieval than by the content they retrieved: — Daniel Kahneman

Social scientists emphasize that people use the "availability heuristic," which means that we assess risks by asking whether a bad (or good) event is cognitively "available." It — Cass R. Sunstein

On another occasion, Amos and I wondered about the rate of divorce among professors in our university. We noticed that the question triggered a search of memory for divorced professors we knew or knew about, and that we judged the size of categories by the ease with which instances came to mind. We called this reliance on the ease of memory search the availability heuristic. — Daniel Kahneman

the availability heuristic. We draw on what is readily available as truth and generalize this information as knowledge. — Deborah L. Plummer

If someone you know gets sick from taking a flu shot, you will be less likely to get one even if it is statistically safe. In fact, if you see a story on the news about someone dying from the flu shot, that one isolated case could me enough to keep you away from the vaccine forever. On the other hand, if you hear a news story about how eating sausage leads to anal cancer, you will be skeptical, because it has never happened to anyone you know, and sausage, after all, is delicious. The tendency to react more rapidly and to a greater degree when considering information you are familiar with is called the availability heuristic. — David McRaney

The second illusion is historical myopia: the closer an era is to our vantage point in the present, the more details we can make out. Historical myopia can afflict both common sense and professional history. The cognitive psychologists Amos Tversky and Daniel Kahneman have shown that people intuitively estimate relative frequency using a shortcut called the availability heuristic: the easier it is to recall examples of an event, the more probable people think it is.10 People, for example, overestimate the likelihoods of the kinds of accidents that make headlines, such as plane crashes, shark attacks, and terrorist bombings, and they underestimate those that pile up unremarked, like electrocutions, falls, and drownings. — Steven Pinker

The answer was straightforward: instances of the class will be retrieved from memory, and if retrieval is easy and fluent, the category will be judged to be large. We defined the availability heuristic as the process of judging frequency by the ease with which instances come to mind. — Daniel Kahneman

For example, students of policy have noted that the availability heuristic
helps explain why some issues are highly salient in the public's mind while
others are neglected. People tend to assess the relative importance of
issues by the ease with which they are retrieved from memory - and this is
largely determined by the extent of coverage in the media — Daniel Kahneman
