Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment. They are often studied in psychology, sociology and behavioral economics. [1] Although the reality of most of these biases is confirmed by reproducible research, [2] [3] there are often controversies about how to classify these biases or how to ...
The most common approach to measuring the Dunning–Kruger effect is to compare self-assessment with objective performance. The self-assessment is sometimes called subjective ability in contrast to the objective ability corresponding to the actual performance. [7] The self-assessment may be done before or after the performance. [9]
The overconfidence effect is a well-established bias in which a person's subjective confidence in their judgments is reliably greater than the objective accuracy of those judgments, especially when confidence is relatively high. [1] [2] Overconfidence is one example of a miscalibration of subjective probabilities.
Retrospective performance outcomes can be used in investigation of the self-serving bias. An example of this is reported company performance followed up by self-report of outcome attributions. [9] These self-report attributions can then be used to assess how successes and failures are viewed by company employees and executives.
For example, participants who received negative feedback on a laboratory task were more likely to attribute their task performance to external, rather than internal, factors. The self-serving bias seems to function as an ego-protection mechanism , helping people to better cope with personal failures.
Illusory superiority has been found in individuals' comparisons of themselves with others in a variety of aspects of life, including performance in academic circumstances (such as class performance, exams and overall intelligence), in working environments (for example in job performance), and in social settings (for example in estimating one's ...
Cognitive bias mitigation and cognitive bias modification are forms of debiasing specifically applicable to cognitive biases and their effects. Reference class forecasting is a method for systematically debiasing estimates and decisions, based on what Daniel Kahneman has dubbed the outside view .
The halo effect is a perception distortion (or cognitive bias) that affects the way people interpret the information about someone with whom they have formed a positive gestalt. [11] An example of the halo effect is when a person finds out someone they have formed a positive gestalt with has cheated on their taxes.
