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.
