It is one of a group of heuristics (simple rules governing judgment or decision-making) proposed by psychologists Amos Tversky and Daniel Kahneman in the early 1970s. May result in cognitive biases. Heuristics are simple for the brain to compute but sometimes introduce "severe and systematic errors." Write down your reasoning and then match it to the outcomes, whether good or bad. We’re going to ignore other potentially relevant information when we’re comparing to a prototype so there’s a danger to this representativeness heuristic and how it can lead us to make errors that can have important consequences. Read on to understand the representativeness heuristic.

How are both of these heuristics different then an algorithm? Have questions or topics you’d like to see covered in a future video? The problem arises from stereotyping in these situations.

Rather than using relevant base rate information, participants showed a tendency to rely on prototypes when making this decision. In short, the prototype serves as an example of the representativeness of the specific patient in question. What are the odds Adam is a lawyer or an engineer? Representativeness Heuristic Definition According to some social psychologists, human beings have the tendency to be cognitive misers—that is, to limit their use of mental resources when they need to make a quick decision or when the issue about which they must make a decision is unimportant to them. Your brain has categorized people and things into different buckets based on various features. How well does this match my prototype of that.
