cess known as the representativeness heuristic, while in other, similar contexts, the To demonstrate the tendency for people to ignore base rates,. Tversky and According to statistical theory, predictions may deviate from base rates only to the extent of the base rate increased systematically as differential representativeness A. Tversky (Eds.),Judgment under uncertainty: Heuristics and biases (pp. study simultaneously demonstrate the substitution of representativeness for probability and the neglect of known (but not explicitly mentioned) base rates. Insert gambler's fallacy, availability and representativeness heuristics, confirmation bias, believe perseveration, base-rate fallacy, priming, overconfidence effect.
The representativeness heuristic is used when The base rate fallacy describes how people do not take the base rate of an event into account when solving probability
Recall that base rate neglect resulting from the representativeness heuristic constitutes a failure to incorporate relevant information into the judgment. To nullify this error, a heuristic is The representativeness heuristic was first described by psychologists Amos Tversky and Daniel Kahneman during the 1970s. Like other heuristics, making judgments based on representativeness is intended to work as a type of mental shortcut, allowing us to make decisions quickly. However, it can also lead to errors. The key issue for social psychologists, then, is to understand when the base rate fallacy is likely to emerge and when it is not. At least four major factors are known to moderate people’s use of base rates in judgments and decisions. That is the base rate. Now, consider the characteristic “retiring.” Suppose half of all male librarians are retiring, whereas only 5 percent of salesmen are. That works out to 10 retiring salesmen for every retiring librarian — making the odds that Jones is a librarian closer to 10 percent than to 90 percent. The representativeness heuristic is a mental shortcut that helps us make a decision by comparing information to our mental prototypes. Unfortunately, many examples of the representativeness heuristic involve succumbing to stereotypes. Finally, the base-rate heuristic is a mental shortcut that helps us make a decision based on probability. This The representativeness heuristic is a psychological term wherein people judge the probability or frequency of a hypothesis by considering how much the hypothesis resembles available data as opposed to using a Bayesian calculation. While often very useful in everyday life, it can also result in neglect of relevant base rates and other cognitive biases. The …

useful in many situations, can lead even the most intelligent people to make dumb decisions: availability, representativeness, and base-rate heuristics. Representativeness. Heuristic. Jay W. Pope.

Two experiments provide insight into The use of the representativeness heuristic by second, fourth, and sixth graders showed a developmental increase in (a) base rate information and (b) The representativeness heuristic, for example, is argued to cause biases such as misperception of regression, the conjunction fallacy, and base-rate neglect
2 Sep 2019 Biases in judgments reveal some heuristics of thinking under the representativeness heuristic, in t y is the prior probability, or base-rate.

The whole idea of cognitive biases and faulty heuristics—the shortcuts and rules of to base-rate neglect (a form of the representativeness heuristic) is “None.
The base rate fallacy can be observed when an attribute of an individual is assessed based solely upon the individual and not upon the rate at which the attribute occurs in the population. Misperception of randomness can also be a product of representativeness heuristics.
