Representativeness Heuristic
Representativeness heuristic is a cognitive bias that refers to the tendency of people to rely on prototypes or stereotypes in making judgments and decisions. It is a mental shortcut that allows individuals to quickly categorize and make sense of new information based on what they already know. However, this heuristic can often lead to errors in judgment, as people may overlook important information that does not fit their preconceived notions. One example of representativeness heuristic is the gambler's fallacy, where individuals believe that the outcome of a random event is more likely to occur if it has not happened recently. For instance, a person may believe that a coin is more likely to land on heads if it has landed on tails several times in a row. This is a fallacy because each coin toss is independent of the previous one and has an equal chance of landing on either heads or tails. Another example of representativeness heuristic is the base rate fallacy, where individuals ignore statistical information about the likelihood of an event occurring in a population and instead rely on their personal experiences or stereotypes. For instance, a person may believe that all lawyers are wealthy, even though the majority of lawyers may not be. Representativeness heuristic can also lead to stereotyping and discrimination, as individuals may make judgments based on superficial characteristics such as race, gender, or age. This can result in unfair treatment and missed opportunities for individuals who do not fit the prototype or stereotype. In conclusion, representativeness heuristic is a cognitive bias that can have both positive and negative effects on decision making. While it can be a useful mental shortcut, it can also lead to errors in judgment and discrimination. It is important for individuals to be aware of this bias and to take into account all relevant information when making decisions.

Representativeness Heuristic
Representativeness heuristic is a type of cognitive bias that happens when people make judgments and decisions based on how similar something is to a typical example of something else. For example, if a child sees a bird in a tree, they might assume it's a sparrow because sparrows are the most common types of birds they have seen before. This kind of thinking often leads to incorrect conclusions because it doesn't take into account all of the information that is available.

Representativeness Heuristic
The representativeness heuristic is a cognitive bias in which people tend to judge the likelihood of an event by the degree to which it is similar to a prototype they have in mind. This bias is often seen in decision making, as people focus more on the similarity of an object to a prototype than on its actual properties. For example, a person might assume that a student with a high GPA is likely to be a good employee, even though there may be other factors that are more important for job performance. This heuristic can lead to logical fallacies and incorrect judgments if people do not take into account all of the relevant information.
