We are on a mission to democratize behavioral science. Within each category, there is a “prototype”: the “average” member of a given category that best represents the category as a whole. The representativeness heuristic is the tendency to make an instant decision based on readily available attributes such as looks, behavior, or current known facts. A representativeness heuristic is often useful as is it makes decision-making easier. When people try to determine the probability that an object A belongs to class B, they often use their resentativeness heuristic. People tend to judge the probability of an event by finding a‘comparable known’ event and assuming that the probabilities will besimilar. The restraint bias refers to our tendency to overestimate the level of control we have over our impulsive behaviors. To avoid the representativeness heuristic, learn more about statistics and logical thinking, and ask others to point out instances where you might be relying too much on representativeness. 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). The Power of the Representativeness Heuristic. On an intuitive level, we feel like ulcers and stress must have some connection. She majored in economics at university and, as a student, she was passionate about the issues of equality and discrimination. Think of all the things you are likely to encounter in a single day. Another type of heuristic is a representativeness heuristic, a mental shortcut which helps us make a decision by comparing information to our mental prototypes. After reading this, Tversky and Kahneman had people rank several statements in order of how likely they were to be true. Like other heuristics, making judgments based on representativeness is intended to work as a type of mental shortcut, allowing us to make decisions quickly. For an example, imagine that in an experimental protocol you were given the description of a random person: Catherine is loud, opinionated, intelligent and self-sufficient. The physical sensations people experience because of a stomach ulcer—burning pains, and the feeling of a churning stomach—is similar to what we feel when we’re experiencing stress. Gilovich and Savitsky also argue that the representativeness heuristic plays a role in pseudoscientific beliefs, including astrology. The more one experiences losses, the more likely they are to become prone to loss aversion. Write down your reasoning and then match it to the outcomes, whether good or bad. But when we focus too much on representativeness, sample size can end up being crowded out. For instance, people tend to find faces more attractive the closer they are to the “average” face, as generated by a computer.5. This field is for validation purposes and should be left unchanged. This might seem like a no-brainer, but categories are more fundamental to our ability to function than many people realize. When using the representativeness heuristic you decide whether an example belongs to a certain class or group on the basis of how similar it is to other items in that class or group; Examples: Rich car buyers; A student who belongs to a fraternity or sorority Why did it take so long (and such an extreme measure) to persuade other people to consider this new possibility? She is 31, single, outspoken and very bright. A 280lbs guy that is 6-foot-tall is more likely to be a wrestler than an accountant. The personality types associated with each star sign in astrology are chosen because they are representative of the animal or symbol of that sign. Hindsight bias is the misconception, after the fact, that one "always knew" that they were right. Like goes with like: The role of representativeness in erroneous and pseudoscientific beliefs. In this way, representativeness is basically stereotyping. As a part of creating meaning from what we experience, weneed to classify things. Statistically speaking, this is never true. One of the things you want to think about is that you want to judge things strictly as they are statistically or logically, rather than as they merely appear. On the flip side, the way we have learned to categorize things can also affect how we perceive them.3 For example, in Russian, lighter and darker shades of blue have different names (“goluboy” and “siniy,” respectively), whereas, in English, both are referred to as “blue.” Research has shown that this difference in categorization affects how people see the color blue: Russian speakers are faster at discriminating between light and dark blues, compared to English speakers.4, According to one theory of categorization, known as prototype theory, people use unconscious mental statistics to figure out what the “average” member of a category looks like.
