Step-by-step explanation:
The representative heuristic is the tendency to make judgments about group membership based on physical appearances or the match between a person and one's stereotype of a group, rather than on available base rate information. This means that instead of considering objective data or statistical probabilities, people rely on stereotypes and superficial characteristics to make judgments. For example, if someone sees someone wearing a certain type of clothing associated with a particular group, they may assume that the person is a member of that group, even without any other information.
