The […] The representativeness heuristic is used when making judgments about the probability of an event under uncertainty. [1] It is one of a group of heuristics (simple rules governing judgment or decision-making) proposed by psychologists Amos Tversky and Daniel Kahneman in the early 1970s. Representativeness Heuristic is a cognitive bias explored by Kahneman and Tversky in their article Subjective Probability: A Judgment of Representativeness (1972).

People frequently make the mistake of believing that two similar things or events are more closely correlated than they actually are. The representativeness heuristic involves estimating the likelihood of an event by comparing it to an existing prototype that already exists in our minds. This prototype is what we think is the most relevant or typical example of a particular event or object. The representativeness heuristic is simply described as assessing similarity of objects and organizing them based around the category prototype (e.g., like goes with like, and causes and effects should resemble each other).

These decisions tend to be based on how similar an example is to something else (or how typical or representative the particular case in question is). In this way, representativeness is basically stereotyping. Heuristics and Biases (Tversky and Kahneman 1974) Heuristics are used to reduce mental effort in decision making, but they may lead to systematic biases or errors in judgment. 1.
