[22], The recognition heuristic exploits the basic psychological capacity for recognition in order to make inferences about unknown quantities in the world. Averaged Correlations: Demonstrating the Warm Glow Heuristic Beyond Aggregation", "Some Effects of Moral Indignation on Law", "Think Fast! Half of the participants were told to use a tallying strategy, in which one counts the number of cues favoring one alternative over the other, or to use a take-the-best strategy, in which one uses only the most predictive cue to make a decision. If the outcome is negative, then the testing procedure stops and the client is informed of the good news, that is, “no HIV.” If, however, the result is positive, a second ELISA test is performed, preferably from a different manufacturer. A model of a heuristic describes the steps of this process. Concepts — What âprinciplesâ or âtheoriesâ (or even heuristics are at play here, and are they worth questioning? In the case of the HIV tree, the ELISA is ranked first because it produces fewer misses than the Western blot test, and also is less expensive. Rule of thumb. Another group had to rate how likely it is that Tom specialised in each area. [63] Subjects in these experiments lack introspective awareness of the heuristic, denying that the anchor affected their estimates. Hence the anchor contaminates the estimate, even if it is clearly irrelevant. Inferences — What can be deduced from the information you already have? Their typical experimental setup consisted of a rule of logic or probability, embedded in a verbal description of a judgement problem, and demonstrated that people's intuitive judgement deviated from the rule.

In fact, the term heuristic and bias became almost synonymous and were used interchangeably. Point of view — From what perspective are you currently thinking? Their interpretation was biased towards the emotion they had been primed with: the more priming, the greater the effect. Here’s an example: Which is more valuable? Therefore, that person automatically has more credibility and is more likely to trust the content of the messages than they deliver. A greater interval between the initial task and the judgment decreased the effect. Authority. Itâs the journey towards good judgment that matters. Take-the-best has remarkable properties. Unlike a full decision tree, however, it is an incomplete tree – to save time and reduce the danger of overfitting. In one block, the majority of responses were selfish (not investing in the common pool) across trials, whereas in the other half of trials the majority of responses were altruistic (investing in the common pool) across trials. Everyone in these versions of the study recognised that out of 100 people fitting an outline description, the conjunction statement ("She is X and Y") cannot apply to more people than the general statement ("She is X"). Representativeness explains this and several other ways in which human judgments break the laws of probability. Moreover, moral judgments were faster when the behavior was common, and average morality rating was a strong predictor of the likelihood that the participant would choose the selfish action when they themselves played a subsequent one-shot public goods game. However, this heuristic can also produce errors. [40], A concept's availability can be affected by how recently and how frequently it has been brought to mind.
