In social psychology, fundamental attribution error (FAE), also known as correspondence bias or attribution effect, is the tendency for people to under-emphasize situational and environmental explanations for an individual's observed behavior while over-emphasizing dispositional and personality-based explanations. This effect has been described as "the tendency to believe that what people do reflects who they are",[1] that is, to see a person's given action to be reflective of their personality as a whole rather than being brought on by current and recent circumstances.

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 explain them.[4] Several theoretical causes are known for some cognitive biases, which provides a classification of biases by their common generative mechanism (such as noisy information-processing[5]). Gerd Gigerenzer has criticized the framing of cognitive biases as errors in judgment, and favors interpreting them as arising from rational deviations from logical thought.[6]
Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. Biases have a variety of forms and appear as cognitive ("cold") bias, such as mental noise,[5] or motivational ("hot") bias, such as when beliefs are distorted by wishful thinking. Both effects can be present at the same time.[7][8]
There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior. For example, when getting to know others, people tend to ask leading questions which seem biased towards confirming their assumptions about the person. However, this kind of confirmation bias has also been argued to be an example of social skill; a way to establish a connection with the other person.[9]
Although this research overwhelmingly involves human subjects, some findings that demonstrate bias have been found in non-human animals as well. For example, loss aversion has been shown in monkeys and hyperbolic discounting has been observed in rats, pigeons, and monkeys.[10]
Belief, decision-making and behavioral[edit]
These biases affect belief formation, reasoning processes, business and economic decisions, and human behavior in general.
| Name | Type | Description |
|---|---|---|
| Additive bias | The tendency to solve problems through addition, even when subtraction is a better approach.[11][12] | |
| Agent detection | False priors | The inclination to presume the purposeful intervention of a sentient or intelligent agent. |
| Ambiguity effect | Prospect theory | The tendency to avoid options for which the probability of a favorable outcome is unknown.[13] |
| Anchoring or focalism | Anchoring bias | The tendency to rely too heavily, or "anchor", on one trait or piece of information when making decisions (usually the first piece of information acquired on that subject).[14][15] |
| Anthropocentric thinking | Availability bias | The tendency to use human analogies as a basis for reasoning about other, less familiar, biological phenomena.[16] |
| Anthropomorphism or personification | Availability bias | The tendency to characterize animals, objects, and abstract concepts as possessing human-like traits, emotions, and intentions.[17] The opposite bias, of not attributing feelings or thoughts to another person, is dehumanised perception,[18]a type of objectification. |
| Attentional bias | Availability bias | The tendency of perception to be affected by recurring thoughts.[19] |
| Attribute substitution | Occurs when a judgment has to be made (of a target attribute) that is computationally complex, and instead a more easily calculated heuristic attribute is substituted. This substitution is thought of as taking place in the automatic intuitive judgment system, rather than the more self-aware reflective system. | |
| Automation bias | False priors | The tendency to depend excessively on automated systems which can lead to erroneous automated information overriding correct decisions.[20] |
| Availability heuristic | Availability bias | The tendency to overestimate the likelihood of events with greater "availability" in memory, which can be influenced by how recent the memories are or how unusual or emotionally charged they may be.[21] |

| Congruence bias | Confirmation bias | The tendency to test hypotheses exclusively through direct testing, instead of testing possible alternative hypotheses.[15] |
| Conjunction fallacy | Extension neglect | The tendency to assume that specific conditions are more probable than a more general version of those same conditions.[29] |
| Conservatism bias (belief revision) | Anchoring bias | The tendency to revise one's belief insufficiently when presented with new evidence.[5][30][31] |
| Continued influence effect | Confirmation bias | The tendency to believe previously learned misinformation even after it has been corrected. Misinformation can still influence inferences one generates after a correction has occurred.[32] cf. Backfire effect |

| Endowment effect | Prospect theory | The tendency for people to demand much more to give up an object than they would be willing to pay to acquire it.[45] |
| Exaggerated expectation | The tendency to expect or predict more extreme outcomes than those outcomes that actually happen.[5] | |
| Experimenter's or expectation bias | Confirmation bias | The tendency for experimenters to believe, certify, and publish data that agree with their expectations for the outcome of an experiment, and to disbelieve, discard, or downgrade the corresponding weightings for data that appear to conflict with those expectations.[46] |
| Forer effect or Barnum effect | Egocentric bias | The observation that individuals will give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically for them, but are in fact vague and general enough to apply to a wide range of people. This effect can provide a partial explanation for the widespread acceptance of some beliefs and practices, such as astrology, fortune telling, graphology, and some types of personality tests.[47] |
| Form function attribution bias | In human–robot interaction, the tendency of people to make systematic errors when interacting with a robot. People may base their expectations and perceptions of a robot on its appearance (form) and attribute functions which do not necessarily mirror the true functions of the robot.[48] | |
| Framing effect | Framing effect | Drawing different conclusions from the same information, depending on how that information is presented. |
| Frequency illusion or Baader–Meinhof phenomenon | Availability bias | The frequency illusion is that once something has been noticed then every instance of that thing is noticed, leading to the belief it has a high frequency of occurrence (a form of selection bias).[49] The Baader–Meinhof phenomenon is the illusion where something that has recently come to one's attention suddenly seems to appear with improbable frequency shortly afterwards.[50][51] It was named after an incidence of frequency illusion in which the Baader–Meinhof Group was mentioned.[52] |
| Functional fixedness | Anchoring bias | Limits a person to using an object only in the way it is traditionally used.[53] |
| Gambler's fallacy | Logical fallacy | The tendency to think that future probabilities are altered by past events, when in reality they are unchanged. The fallacy arises from an erroneous conceptualization of the law of large numbers. For example, "I've flipped heads with this coin five times consecutively, so the chance of tails coming out on the sixth flip is much greater than heads."[54] |
| Gender bias | False priors | A widely held[55] set of implicit biases that discriminate against a gender. For example, the assumption that women are less suited to jobs requiring high intellectual ability.[56] Or the assumption that people or animals are male in the absence of any indicators of gender.[57] |

| Hungry judge effect | Judicial decision making and mood may be affected by physiological factors such as what the judge had for breakfast. | |
| Hyperbolic discounting | Extension neglect | Discounting is the tendency for people to have a stronger preference for more immediate payoffs relative to later payoffs. Hyperbolic discounting leads to choices that are inconsistent over time – people make choices today that their future selves would prefer not to have made, despite using the same reasoning.[62] Also known as current moment bias, present-bias, and related to Dynamic inconsistency. A good example of this: a study showed that when making food choices for the coming week, 74% of participants chose fruit, whereas when the food choice was for the current day, 70% chose chocolate. |

| Irrational escalation or Escalation of commitment | Logical fallacy | The phenomenon where people justify increased investment in a decision, based on the cumulative prior investment, despite new evidence suggesting that the decision was probably wrong. Also known as the sunk cost fallacy. |
| Law of the instrument | Anchoring bias | An over-reliance on a familiar tool or methods, ignoring or under-valuing alternative approaches. "If all you have is a hammer, everything looks like a nail." |
| Less-is-better effect | Extension neglect | The tendency to prefer a smaller set to a larger set judged separately, but not jointly. |
| Loss aversion | Prospect theory | The perceived disutility of giving up an object is greater than the utility associated with acquiring it.[74] (see also Sunk cost effects and endowment effect). |

| Plant blindness | The tendency to ignore plants in their environment and a failure to recognize and appreciate the utility of plants to life on earth.[87] | |
| Prevention bias | When investing money to protect against risks, decision makers perceive that a dollar spent on prevention buys more security than a dollar spent on timely detection and response, even when investing in either option is equally effective.[88] | |

| Proportionality bias | Our innate tendency to assume that big events have big causes, may also explain our tendency to accept conspiracy theories.[92][93] | |
| Pseudocertainty effect | Prospect theory | The tendency to make risk-averse choices if the expected outcome is positive, but make risk-seeking choices to avoid negative outcomes.[94] |
| Recency illusion | The illusion that a phenomenon one has noticed only recently is itself recent. Often used to refer to linguistic phenomena; the illusion that a word or language usage that one has noticed only recently is an innovation when it is, in fact, long-established (see also frequency illusion). Also Recency bias is a cognitive bias that favors recent events over historic ones. A memory bias, recency bias gives "greater importance to the most recent event",[95] such as the final lawyer's closing argument a jury hears before being dismissed to deliberate. | |

| Subjective validation | Truthiness | Perception that something is true if a subject's belief demands it to be true. Also assigns perceived connections between coincidences. |
| Surrogation | Losing sight of the strategic construct that a measure is intended to represent, and subsequently acting as though the measure is the construct of interest. | |
| Survivorship bias | Availability bias | Concentrating on the people or things that "survived" some process and inadvertently overlooking those that didn't because of their lack of visibility. |
| System justification | Prospect theory | The tendency to defend and bolster the status quo. Existing social, economic, and political arrangements tend to be preferred, and alternatives disparaged, sometimes even at the expense of individual and collective self-interest. (See also status quo bias.) |
| Time-saving bias | Logical fallacy | Underestimations of the time that could be saved (or lost) when increasing (or decreasing) from a relatively low speed and overestimations of the time that could be saved (or lost) when increasing (or decreasing) from a relatively high speed. |
| Parkinson's law of triviality | The tendency to give disproportionate weight to trivial issues. Also known as bikeshedding, this bias explains why an organization may avoid specialized or complex subjects, such as the design of a nuclear reactor, and instead focus on something easy to grasp or rewarding to the average participant, such as the design of an adjacent bike shed.[100] | |
| Unconscious bias | Also known as implicit biases, are the underlying attitudes and stereotypes that people unconsciously attribute to another person or group of people that affect how they understand and engage with them. Many researchers suggest that unconscious bias occurs automatically as the brain makes quick judgments based on past experiences and background.[101] | |
| Unit bias | The standard suggested amount of consumption (e.g., food serving size) is perceived to be appropriate, and a person would consume it all even if it is too much for this particular person.[102] | |

Memory[edit]
In psychology and cognitive science, a memory bias is a cognitive bias that either enhances or impairs the recall of a memory (either the chances that the memory will be recalled at all, or the amount of time it takes for it to be recalled, or both), or that alters the content of a reported memory. There are many types of memory bias, including:
| Name | Description |
|---|---|
| Bizarreness effect | Bizarre material is better remembered than common material. |
| Choice-supportive bias | The tendency to remember one's choices as better than they actually were.[127] |
| Conservatism or Regressive bias | Tendency to remember high values and high likelihoods/probabilities/frequencies as lower than they actually were and low ones as higher than they actually were. Based on the evidence, memories are not extreme enough.[128][129] |
| Consistency bias | Incorrectly remembering one's past attitudes and behaviour as resembling present attitudes and behaviour.[130] |
| Context effect | That cognition and memory are dependent on context, such that out-of-context memories are more difficult to retrieve than in-context memories (e.g., recall time and accuracy for a work-related memory will be lower at home, and vice versa). |
| Cross-race effect | The tendency for people of one race to have difficulty identifying members of a race other than their own. |
| Cryptomnesia | A form of misattribution where a memory is mistaken for imagination, because there is no subjective experience of it being a memory.[131] |
| Egocentric bias | Recalling the past in a self-serving manner, e.g., remembering one's exam grades as being better than they were, or remembering a caught fish as bigger than it really was. |
| Fading affect bias | A bias in which the emotion associated with unpleasant memories fades more quickly than the emotion associated with positive events.[132] |
| False memory | A form of misattribution where imagination is mistaken for a memory. |
| Generation effect (Self-generation effect) | That self-generated information is remembered best. For instance, people are better able to recall memories of statements that they have generated than similar statements generated by others. |
| Google effect | The tendency to forget information that can be found readily online by using Internet search engines. |
| Humor effect | That humorous items are more easily remembered than non-humorous ones, which might be explained by the distinctiveness of humor, the increased cognitive processing time to understand the humor, or the emotional arousal caused by the humor.[133] |
| Lag effect | The phenomenon whereby learning is greater when studying is spread out over time, as opposed to studying the same amount of time in a single session. See also spacing effect. |
| Leveling and sharpening | Memory distortions introduced by the loss of details in a recollection over time, often concurrent with sharpening or selective recollection of certain details that take on exaggerated significance in relation to the details or aspects of the experience lost through leveling. Both biases may be reinforced over time, and by repeated recollection or re-telling of a memory.[134] |
| Levels-of-processing effect | That different methods of encoding information into memory have different levels of effectiveness.[135] |
| List-length effect | A smaller percentage of items are remembered in a longer list, but as the length of the list increases, the absolute number of items remembered increases as well. For example, consider a list of 30 items ("L30") and a list of 100 items ("L100"). An individual may remember 15 items from L30, or 50%, whereas the individual may remember 40 items from L100, or 40%. Although the percent of L30 items remembered (50%) is greater than the percent of L100 (40%), more L100 items (40) are remembered than L30 items (15).[136][further explanation needed] |
| Misinformation effect | Memory becoming less accurate because of interference from post-event information.[137] |
| Modality effect | That memory recall is higher for the last items of a list when the list items were received via speech than when they were received through writing. |
| Mood-congruent memory bias | The improved recall of information congruent with one's current mood. |
| Negativity bias or Negativity effect | Psychological phenomenon by which humans have a greater recall of unpleasant memories compared with positive memories.[138][91](see also actor-observer bias, group attribution error, positivity effect, and negativity effect).[113] |
| Next-in-line effect | When taking turns speaking in a group using a predetermined order (e.g. going clockwise around a room, taking numbers, etc.) people tend to have diminished recall for the words of the person who spoke immediately before them.[139] |
| Part-list cueing effect | That being shown some items from a list and later retrieving one item causes it to become harder to retrieve the other items.[140] |
| Peak–end rule | That people seem to perceive not the sum of an experience but the average of how it was at its peak (e.g., pleasant or unpleasant) and how it ended. |
| Picture superiority effect | The notion that concepts that are learned by viewing pictures are more easily and frequently recalled than are concepts that are learned by viewing their written word form counterparts.[141][142][143][144][145][146] |
| Positivity effect (Socioemotional selectivity theory) | That older adults favor positive over negative information in their memories. |
| Serial position effect | That items near the end of a sequence are the easiest to recall, followed by the items at the beginning of a sequence; items in the middle are the least likely to be remembered.[147] |
| Processing difficulty effect | That information that takes longer to read and is thought about more (processed with more difficulty) is more easily remembered.[148] |
| Reminiscence bump | The recalling of more personal events from adolescence and early adulthood than personal events from other lifetime periods.[149] |
| Self-relevance effect | That memories relating to the self are better recalled than similar information relating to others. |
| Source confusion | Confusing episodic memories with other information, creating distorted memories.[150] |
| Spacing effect | That information is better recalled if exposure to it is repeated over a long span of time rather than a short one. |
| Spotlight effect | The tendency to overestimate the amount that other people notice your appearance or behavior. |
| Stereotype bias | Memory distorted towards stereotypes (e.g., racial or gender). |
| Suffix effect | Diminishment of the recency effect because a sound item is appended to the list that the subject is not required to recall.[151][152] |
| Suggestibility | A form of misattribution where ideas suggested by a questioner are mistaken for memory. |
| Tachypsychia | When time perceived by the individual either lengthens, making events appear to slow down, or contracts.[153] |
| Telescoping effect | The tendency to displace recent events backwards in time and remote events forward in time, so that recent events appear more remote, and remote events, more recent. |
| Testing effect | The fact that you more easily remember information you have read by rewriting it instead of rereading it.[154] |
| Tip of the tongue phenomenon | When a subject is able to recall parts of an item, or related information, but is frustratingly unable to recall the whole item. This is thought to be an instance of "blocking" where multiple similar memories are being recalled and interfere with each other.[131] |
| Travis Syndrome | Overestimating the significance of the present.[155] It is related to chronological snobbery with possibly an appeal to novelty logical fallacybeing part of the bias. |
| Verbatim effect | That the "gist" of what someone has said is better remembered than the verbatim wording.[156] This is because memories are representations, not exact copies. |
| von Restorff effect | That an item that sticks out is more likely to be remembered than other items.[157] |
| Zeigarnik effect | That uncompleted or interrupted tasks are remembered better than completed ones. |
