mathematics and plausible reasoning 71 contemporary edit the study of heuristics in human decision making was developed in the 1970s and the 1980s by the psychologists amos tversky and daniel kahneman 81 although the concept had been originally introduced by the nobel laureate herbert a simon simon s original primary object of research was problem solving that showed that we operate within what he calls bounded rationality he coined the term satisficing which denotes a situation in which people seek solutions or accept choices or judgements that are good enough for their purposes although they could be optimised 82 rudolf groner analysed the history of heuristics from its roots in ancient greece up to contemporary work in cognitive psychology and artificial intelligence 83 proposing a cognitive style heuristic versus algorithmic thinking which can be assessed by means of a validated questionnaire 84 adaptive toolbox edit the adaptive toolbox contains strategies for fabricating heuristic devices 85 the core mental capacities are recall memory frequency object permanence and imitation 86 gerd gigerenzer and his research group argued that models of heuristics need to be formal to allow for predictions of behavior that can be tested 87 they study the fast and frugal heuristics in the adaptive toolbox of individuals or institutions and the ecological rationality of these heuristics that is the conditions under which a given heuristic is likely to be successful 88 the descriptive study of the adaptive toolbox is done by observation and experiment while the prescriptive study of ecological rationality requires mathematical analysis and computer simulation heuristics such as the recognition heuristic the take the best heuristic and fast and frugal trees have been shown to be effective in predictions particularly in situations of uncertainty it is often said that heuristics trade accuracy for effort but this is only the case in situations of risk risk refers to situations where all possible actions their outcomes and probabilities are known in the absence of this information that is under uncertainty heuristics can achieve higher accuracy with lower effort 89 this finding known as a less is more effect would not have been found without formal models the valuable insight of this program is that heuristics are effective not despite their simplicity but because of it furthermore gigerenzer and wolfgang gaissmaier found that both individuals and organisations rely on heuristics in an adaptive way 90 cognitive experiential self theory edit heuristics through greater refinement and research have begun to be applied to other theories or be explained by them for example the cognitive experiential self theory cest is also an adaptive view of heuristic processing cest breaks down two systems that process information at some times roughly speaking individuals consider issues rationally systematically logically deliberately effortfully and verbally on other occasions individuals consider issues intuitively effortlessly globally and emotionally 91 from this perspective heuristics are part of a larger experiential processing system that is often adaptive but vulnerable to error in situations that require logical analysis 92 attribute substitution edit in 2002 daniel kahneman and shane frederick proposed that cognitive heuristics work by a process called attribute substitution which happens without conscious awareness 93 according to this theory when somebody makes a judgement of a target attribute that is computationally complex a more easily calculated heuristic attribute is substituted in effect a cognitively difficult problem is dealt with by answering a rather simpler problem without being aware of this happening 93 this theory explains cases where judgements fail to show regression toward the mean 94 heuristics can be considered to reduce the complexity of clinical judgments in health care 95 academic disciplines edit psychology edit main article heuristic psychology for broader coverage of this topic see phenomenology psychology see also decision making in psychology heuristics are simple efficient rules either learned or inculcated by evolutionary processes these psychological heuristics have been proposed to explain how people make decisions come to judgements and solve problems these rules typically come into play when people face complex problems or incomplete information researchers employ various methods to test whether people use these rules the rules have been shown to work well under most circumstances but in certain cases can lead to systematic errors or cognitive biases 96 philosophy edit a heuristic device is used when an entity x exists to enable understanding of or knowledge concerning some other entity y a good example is a model that as it is never identical with what it models is a heuristic device to enable understanding of what it models stories metaphors etc can also be termed heuristic in this sense a classic example is the notion of utopia as described in plato s best known work the republic this means that the ideal city as depicted in the republic is not given as something to be pursued or to present an orientation point for development rather it shows how things would have to be connected and how one thing would lead to another often with highly problematic results if one opted for certain principles and carried them through rigorously heuristic is also often used as a noun to describe a rule of thumb procedure or method 97 philosophers of science have emphasised the importance of heuristics in creative thought and the construction of scientific theories 98 seminal works include karl popper s the logic of scientific discovery and others by imre lakatos 99 lindley darden and william c wimsatt law edit in legal theory especially in the theory of law and economics heuristics are used in the law when case by case analysis would be impractical insofar as practicality is defined by the interests of a governing body 100 the present securities regulation regime largely assumes that all investors act as perfectly rational persons in truth actual investors face cognitive limitations from biases heuristics and framing effects for instance in all states in the united states the legal drinking age for unsupervised persons is 21 years because it is argued that people need to be mature enough to make decisions involving the risks of alcohol consumption however assuming people mature at different rates the specific age of 21 would be too late for some and too early for others in this case the somewhat arbitrary delineation is used because it is impossible or impractical to tell whether an individual is sufficiently mature for society to trust them with that kind of responsibility some proposed changes however have included the completion of an alcohol education course rather than the attainment of 21 years of age as the criterion for legal alcohol possession this would put youth alcohol policy more on a case by case basis and less on a heuristic one since the completion of such a course would presumably be voluntary and not uniform across the population the same reasoning applies to patent law patents are justified on the grounds that inventors must be protected so they have incentive to invent it is therefore argued that it is in society s best interest that inventors receive a temporary government granted monopoly on their idea so that they can recoup investment costs and make economic profit for a limited period in the united states the length of this temporary monopoly is 20 years from the date the patent application was filed though the monopoly does not actually begin until the application has matured into a patent however like the drinking age problem above the specific length of time would need to be different for every product to be efficient a 20 year term is used because it is difficult to tell what the number should be for any individual patent more recently some including university of north dakota law professor eric e johnson have argued that patents in different kinds of industries such as software patents should be protected for different lengths of time 101 artificial intelligence edit the bias variance tradeoff gives insight into describing the less is more strategy 102 a heuristic can be used in artificial intelligence systems while searching a solution space the heuristic is derived by using some function that is put into the system by the designer or by adjusting the weight of branches based on how likely each branch is to lead to a goal node behavioural economics edit heuristics refers to the cognitive shortcuts that individuals use to simplify decision making processes in economic situations behavioral economics is a field that integrates insights from psychology and economics to better understand how people make decisions anchoring and adjustment is one of the most extensively researched heuristics in behavioural economics anchoring is the tendency of people to make future judgements or conclusions based too heavily on the original information supplied to them this initial knowledge functions as an anchor and it can influence future judgements even if the anchor is entirely unrelated to the decisions at hand adjustment on the other hand is the process through which individuals make gradual changes to their initial judgements or conclusions anchoring and adjustment has been observed in a wide range of decision making contexts including financial decision making consumer behavior and negotiation researchers have identified a number of strategies that can be used to mitigate the effects of anchoring and adjustment including providing multiple anchors encouraging individuals to generate alternative anchors and providing cognitive prompts to encourage more deliberative decision making other heuristics studied in behavioral economics include the representativeness heuristic which refers to the tendency of individuals to categorize objects or events based on how similar they are to typical examples 103 and the availability heuristic which refers to the tendency of individuals to judge the likelihood of an event based on how easily it comes to mind 104 stereotyping edit stereotyping is a type of heuristic that people use to form opinions or make judgements about things they have never seen or experienced 105 they work as a mental shortcut to assess everything from the social status of a person based on their actions 12 to classifying a plant as a tree based on it being tall having a trunk and that it has leaves even though the person making the evaluation might never have seen that particular type of tree before stereotypes as first described by journalist walter lippmann in his book public opinion 1922 are the pictures we have in our heads that are built around experiences as well as what we are told about the world 106 107 see also edit look up heuristic in wiktionary the free dictionary wikibooks has more on the topic of heuristic act r software pages displaying short descriptions with
