Judgment under Uncertainty: Heuristics and Biases

This paper describes three heuristics, or mental operations, that are employed in judgment under uncertainty. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgments and decisions in situations of uncertainty. Unable to display preview. Download preview PDF.

This article described three heuristics that are employed in making judgements under uncertainty: i representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; ii availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and iii adjustment from an anchor, which is usually employed in numerical prediction when a relevant value is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty. Abstract This article described three heuristics that are employed in making judgements under uncertainty: i representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; ii availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and iii adjustment from an anchor, which is usually employed in numerical prediction when a relevant value is available.

Heuristics are simple strategies or mental processes that humans, animals, [1] [2] [3] organizations [4] and machines [5] use to quickly form judgments , make decisions , and find solutions to complex problems. This happens when an individual focuses on the most relevant aspects of a problem or situation to formulate a solution. Some heuristics are more applicable and useful than others depending on the situation. Heuristic processes are used to find the answers and solutions that are most likely to work or be correct. However, heuristics are not always right or the most accurate. In situations of uncertainty, where information is incomplete, [12] heuristics allow for the less-is-more effect , in which less information leads to greater accuracy. Herbert A.

The main purpose of his work was to understand the cognitive and behavioral mechanisms that human beings use to make choices. Briefly, what Simon explains is that to make an efficient decision three steps are necessary: a to identify and list all alternatives; b to determine all consequences resulting from each alternative; and c to compare the precision and efficiency of each one of these consequences. The process of converting all information about a problem into a decision is called judgement, which can be of an analytic or intuitive nature. The level of complexity of a problem influences the kind of judgement, which can be under certainty, when one single solution is possible; under risk, when few outcomes exist, and under uncertainty, when many outcomes are possible. They discovered that our brain, when facing complex decisions, that is, under uncertainty, tries to save energy.
