Judgment under Uncertainty: Heuristics and Biases.

  title={Judgment under Uncertainty: Heuristics and Biases.},
  author={Amos Tversky and Daniel Kahneman},
  volume={185 4157},
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… Expand

Uncertainty handling and cognitive biases in knowledge engineering
The results suggest that, using an automated aid, subjects can write a highly accurate, nearly unbiased set of rules that will predict event type based on three indicators: weight, size, and shape. Expand
The Use of Heuristics in Decision Making Under Risk and Uncertainty
This chapter introduces two main approaches: the heuristics and biases program (including the availability, representativeness, affect, as well as anchoring and adjustment heURistics) and the fast and frugal heuristic approach. Expand
Judgment and Decision-Making
Abstract The cognitive processes of judgment and decision-making (JDM), which are fundamental to all human behavior, have been studied extensively in laboratory experiments. Much JDM research hasExpand
The Similarity Heuristic
Decision makers are often called on to make snap judgments using fast-and- frugal decision rules called cognitive heuristics. Although early research into cognitive heuristics emphasized theirExpand
An introduction to prior information derived from probabilistic judgements: elicitation of knowledge, cognitive bias and herding
Abstract Opinion of geological experts is often formed despite a paucity of data and is usually based on prior experience. In such situations humans employ heuristics (rules of thumb) to aid analysisExpand
Weighting and Trimming: Heuristics for Aggregating Judgments under Uncertainty
In making major decisions (e.g., about medical treatment, acceptance of manuscripts for publication, or investment), decision makers frequently poll the opinions and subjective estimates of otherExpand
Heuristics for decision and choice
Heuristics are approximate strategies or ‘rules of thumb’ for decision making and problem solving that do not guarantee a correct solution but that typically yield a reasonable solution or bring oneExpand
Epistemic Uncertainty Analysis: An Approach Using Expert Judgment and Evidential Credibility
When dealing with complex systems, all decision making occurs under some level of uncertainty. This is due to the physical attributes of the system being analyzed, the environment in which the systemExpand
Studies in subjective probability II: Dilemmas of chance
The study examines guessing patterns in situations where outcomes have an unequal probability of occurring. It is shown that people will not always predict the most probable outcome if this is anExpand
Heuristics, biases and traps in managerial decision making
This paper focuses on illustrating the existence of the anchoring, availability, and representativeness heuristics, originally described by Tversky & Kahneman in the early 1970’s. Expand

Subjective Probability: A Judgment of Representativeness
This paper explores a heuristic — representativeness — according to which the subjective probability of an event, or a sample, is determined by the degree to which it: (i) is similar in essentialExpand
Availability: A heuristic for judging frequency and probability
A judgmental heuristic in which a person evaluates the frequency of classes or the probability of events by availability, i.e., by the ease with which relevant instances come to mind, is explored. Expand
On the psychology of prediction
In this paper, we explore the rules that determine intuitive predictions and judgments of confidence and contrast these rules to the normative principles of statistical prediction. Two classes ofExpand
Comparison of Bayesian and Regression Approaches to the Study of Information Processing in Judgment.
This work examines the models that have been developed for describing and prescribing the use of information in decision making, the major experimental paradigms, and the major empirical results and conclusions of these two approaches. Expand
The Assessment of Prior Distributions in Bayesian Analysis
Abstract In the Bayesian framework, quantified judgments about uncertainty are an indispensable input to methods of statistical inference and decision. Ultimately, all components of the formalExpand
The experiment was designed to test the hypothesis, derived from earlier investigations, that people tend to overestimate compound probabilities, in the rough sense that they think they have a betterExpand
“Suppose you have run an experiment on 20 subjects, and have obtained a significant result which confirms your theory ( z = 2.23, p If you feel that the probability is somewhere around .85, you mayExpand
On the subjective probability of compound events
Abstract Subjects were requested to choose between gambles, where the outcome of one gamble depended on a single elementary event, and the other depended on an event compounded of a series of suchExpand
Two techniques for assessment of subjective probability distributions — An experimental study☆
Abstract Subjects were asked to assess their subjective probability distributions for unknown parameters of Bernoulli processes. The processes were generated by random devices like, for instance,Expand
