Other cognitive biases are a "by-product" of human processing limitations, resulting from a lack of appropriate mental mechanisms ( bounded rationality), the impact of an individual's constitution and biological state (see embodied cognition), or simply from a limited capacity for information processing.

Overview

The notion of cognitive biases was introduced by Amos Tversky and Daniel Kahneman in 1972 and grew out of their experience of people's ''

. Tversky, Kahneman, and colleagues demonstrated several replicable ways in which human judgments and decisions differ from rational choice theory. Tversky and Kahneman explained human differences in judgment and decision-making in terms of heuristics. Heuristics involve mental shortcuts which provide swift estimates about the possibility of uncertain occurrences. Heuristics are simple for the brain to compute but sometimes introduce "severe and systematic errors." For example, the representativeness heuristic is defined as "The tendency to judge the frequency or likelihood" of an occurrence by the extent of which the event "resembles the typical case". The "Linda Problem" illustrates the representativeness heuristic (Tversky & Kahneman, 1983). Participants were given a description of "Linda" that suggests Linda might well be a feminist (e.g., she is said to be concerned about discrimination and social justice issues). They were then asked whether they thought Linda was more likely to be (a) a "bank teller" or (b) a "bank teller and active in the feminist movement." A majority chose answer (b). This error (mathematically, answer (b) cannot be more likely than answer (a)) is an example of the "

"; Tversky and Kahneman argued that respondents chose (b) because it seemed more "representative" or typical of persons who might fit the description of Linda. The representativeness heuristic may lead to errors such as activating stereotypes and inaccurate judgments of others (Haselton et al., 2005, p. 726). Critics of Kahneman and Tversky, such as

Individuals' susceptibility to some types of cognitive biases can be measured by the Cognitive Reflection Test (CRT) developed by Shane Frederick (2005).


List of biases

The following is a list of the more commonly studied cognitive biases:


Practical significance

. The various biases demonstrated in these psychological experiments suggest that people will frequently fail to do all these things. However, they fail to do so in systematic, directional ways that are predictable. In some academic disciplines, the study of bias is very popular. For instance, bias is a wide spread and well studied phenomenon because most decisions that concern the minds and hearts of entrepreneurs are computationally intractable. Cognitive biases can create other issues that arise in everyday life. One study showed the connection between cognitive bias, specifically approach bias, and inhibitory control on how much unhealthy snack food a person would eat. They found that the participants who ate more of the unhealthy snack food, tended to have less inhibitory control and more reliance on approach bias. Others have also hypothesized that cognitive biases could be linked to various eating disorders and how people view their bodies and their body image. It has also been argued that cognitive biases can be used in destructive ways. Some believe that there are people in authority who use cognitive biases and heuristics in order to manipulate others so that they can reach their end goals. Some medications and other health care treatments rely on cognitive biases in order to persuade others who are susceptible to cognitive biases to use their products. Many see this as taking advantage of one's natural struggle of judgement and decision-making. They also believe that it is the government's responsibility to regulate these misleading ads. Cognitive biases also seem to play a role in property sale price and value. Participants in the experiment were shown a residential property. Afterwards, they were shown another property that was completely unrelated to the first property. They were asked to say what they believed the value and the sale price of the second property would be. They found that showing the participants an unrelated property did have an effect on how they valued the second property.


Reducing

Because they cause systematic errors, cognitive biases cannot be compensated for using a

is a method for systematically debiasing estimates and decisions, based on what Daniel Kahneman has dubbed the outside view. Similar to Gigerenzer (1996), Haselton et al. (2005) state the content and direction of cognitive biases are not "arbitrary" (p. 730). Moreover, cognitive biases can be controlled. One debiasing technique aims to decrease biases by encouraging individuals to use controlled processing compared to automatic processing. In relation to reducing the FAE, monetary incentives and informing participants they will be held accountable for their attributions have been linked to the increase of accurate attributions. Training has also shown to reduce cognitive bias. Carey K. Morewedge and colleagues (2015) found that research participants exposed to one-shot training interventions, such as educational videos and debiasing games that taught mitigating strategies, exhibited significant reductions in their commission of six cognitive biases immediately and up to 3 months later.

refers to the process of modifying cognitive biases in healthy people and also refers to a growing area of psychological (non-pharmaceutical) therapies for anxiety, depression and addiction called cognitive bias modification therapy (CBMT). CBMT is sub-group of therapies within a growing area of psychological therapies based on modifying cognitive processes with or without accompanying medication and talk therapy, sometimes referred to as applied cognitive processing therapies (ACPT). Although cognitive bias modification can refer to modifying cognitive processes in healthy individuals, CBMT is a growing area of evidence-based psychological therapy, in which cognitive processes are modified to relieve suffering from serious depression,

, and addiction. CBMT techniques are technology-assisted therapies that are delivered via a computer with or without clinician support. CBM combines evidence and theory from the cognitive model of anxiety, cognitive neuroscience, and attentional models. Cognitive bias modification has also been used to help those with obsessive-compulsive beliefs and obsessive-compulsive disorder. This therapy has shown that it decreases the obsessive-compulsive beliefs and behaviors.

Individual differences in cognitive biases

People do appear to have stable individual differences in their susceptibility to decision biases such as overconfidence,

. Individual differences in cognitive bias have also been linked to varying levels of cognitive abilities and functions. The Cognitive Reflection Test (CRT) has been used to help understand the connection between cognitive biases and cognitive ability. There have been inconclusive results when using the Cognitive Reflection Test to understand ability. However, there does seem to be a correlation; those who gain a higher score on the Cognitive Reflection Test, have higher cognitive ability and rational-thinking skills. This in turn helps predict the performance on cognitive bias and heuristic tests. Those with higher CRT scores tend to be able to answer more correctly on different heuristic and cognitive bias tests and tasks. Age is another individual difference that has an effect on one's ability to be susceptible to cognitive bias. Older individuals tend to be more susceptible to cognitive biases and have less
cognitive flexibility Cognitive flexibility is an intrinsic property of a cognitive system often associated with the mental ability to adjust its activity and content, switch between different task rules and corresponding behavioral responses, maintain multiple con ...
. However, older individuals were able to decrease their susceptibility to cognitive biases throughout ongoing trials. These experiments had both young and older adults complete a framing task. Younger adults had more cognitive flexibility than older adults. Cognitive flexibility is linked to helping overcome preexisting biases.
