This video comes from a complete social psychology course created in 2015 for Udemy.com. Specifically, when we are trying to assess how likely it is that an event or object A belongs to class B, we tend to make this judgment based on how closely A resembles B (or how representative we believe A is for B). The Representativeness Heuristic: Using Stereotypes. The representativeness heuristic is used when making judgments about the probability of an event under uncertainty. Here I want you to imagine that I have conducted 100 interviews with 70 engineers and 30 lawyers and what I’m going to do is I’m going to mix up all of these assessments and I’m going to randomly pull out a profile and read this person’s profile to you. The yellow car could just be a normal person's car, but I have learned from experience that a large population of … Well if you thought this way, which is how most of the participants in Tversky and Kahneman’s study thought, then you’ve demonstrated this representativeness heuristic. Sorry, your blog cannot share posts by email.

Rather than using relevant base rate information, participants showed a tendency to rely on prototypes when making this decision. Required fields are marked *. First is the representativeness heuristic. For example, the representativeness heuristic is defined as “The tendency to judge the frequency or likelihood" of an occurrence by the extent of which the event "resembles the typical case". 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. People who use this cognitive shortcut bypass more detailed processing of the likelihood of the event in question but instead focus on what (stereotypic) category it … Let’s start out with a couple of definitions: 1. We tend to expect random processes to conform to our idea of randomness—as producing unpatterned, impossible-to-predict outcomes. Compare two similarities and two differences of (representativeness) and (availability) heuristics. Shortform has the world's best summaries of books you should be reading. A popular shortcut method in problem-solving is Representativeness Heuristics. They are generally useful in that make decision-making more simple. The […] The representativeness heuristic is used when making judgments about the probability of an event under uncertainty (Kahneman & Tversky, 1972). The representativeness heuristic argues that people see commonality between items or people of similar appearance, or between an object and a group it appears to be a part of. The third heuristic Tversky and Kahneman identify is the representativeness heuristic, although it might be better termed the “similarity” heuristic. In their seminal work, Tversky and Kahneman introduced three heuristics based on which people make decisions: representativeness, availability, and anchoring. The representativeness heuristic is used when making judgments about the probability of an event under uncertainty. The representativeness heuristic is a mental shortcut that we use when making judgments about the probability. The idea is that shooters get “hot,” and thus should be passed the ball more frequently.
