Ambiguity bias, also known as the ambiguity effect, is a cognitive bias where individuals tend to favor options with known probabilities over those where the probabilities are unknown or ambiguous. This bias stems from a human inclination toward certainty and aversion to unknown risks. When faced with choices, people often prefer what they can understand and predict, even if the predictable choice offers a lesser benefit than an ambiguous one.
Anchoring cognitive bias refers to the human tendency to rely heavily on the first piece of information encountered (the 'anchor') when making decisions. This bias impacts judgment and decision-making processes by disproportionately influencing subsequent thoughts and choices based on the initial anchor point.
The anecdotal fallacy is a cognitive bias where a person relies on personal stories or isolated examples instead of sound arguments or statistical evidence. This fallacy occurs when anecdotal evidence is used in an attempt to prove a point, even when it's not representative of a typical experience. It often disregards broader statistical realities, leading to erroneous conclusions based on sparse data.
The Appeal to Probability fallacy occurs when it is assumed that because something could happen, it will happen. This logical fallacy simplifies complex probabilities into certainties, overlooking other possibilities and uncertainties. It often leads to misleading conclusions and decisions.
The Argument from Fallacy, also known as the fallacy fallacy, is a logical fallacy that assumes that just because an argument contains a fallacy, its conclusion must necessarily be false. This cognitive bias is a form of misinterpretation where individuals erroneously conclude that the presence of flawed reasoning invalidates a proposition's truth.
Attentional bias is a cognitive bias that describes the tendency for people's perception to be affected by their recurring thoughts at the time. It occurs when individuals give disproportionate attention to certain stimuli while ignoring others, often leading to distorted or incomplete perspectives.
Authority bias is a cognitive bias that leads individuals to attribute greater accuracy and truthfulness to the opinion of an authority figure and to be more influenced by their perspective. This bias stems from a natural human tendency to trust and follow the guidance of those who are perceived as experts or leaders.
Automation bias is a specific cognitive bias where humans disproportionately favor information or suggestions output by automated systems, sometimes to the detriment of other important data or their own judgment. This bias can lead individuals to overlook errors or incorrect recommendations made by machines. It is particularly prevalent in situations where automated systems are designed to aid decision-making processes.
The availability heuristic is a cognitive bias that occurs when individuals rely on immediate examples that come to mind while evaluating a situation, idea, or decision. This bias arises from our tendency to give undue weight to information that is readily retrievable from memory, often due to recent exposure or repeated emphasis, rather than considering broader data sets or statistical realities.
The backfire effect is a cognitive bias that manifests when individuals faced with evidence contradicting their beliefs not only resist changing their perspective but may also strengthen their original belief. This anomaly highlights the complexity of human cognition where reason and rational evidence do not always align with changing deeply rooted convictions.
The bandwagon effect is a psychological phenomenon where individuals adopt certain behaviors, styles, or attitudes simply because others are doing so. This type of cognitive bias under the 'Lack of Meaning' category occurs when people follow the actions or beliefs of others based on the assumption that if numerous people are doing something, it must be correct or beneficial. It is often seen in social, political, and economic contexts.
Belief bias is a type of cognitive bias that occurs when an individual's evaluation of the logical validity of an argument is influenced by the believability of the conclusion. People tend to accept conclusions that align with their existing beliefs and reject those that do not, regardless of the soundness of the supporting premises.
The bias blind spot is a cognitive bias where individuals are unable to detect the impact of biases on their own judgment, but easily notice them in others. It is a part of the broader category of cognitive biases that cause individuals to process information in a flawed manner, particularly when dealing with information overload. This bias affects how people perceive their own objectivity.
Choice-supportive bias is a cognitive bias that leads individuals to remember their choices as better than they actually were, often highlighting the positives of the options they've chosen and downplaying the negatives. This bias can influence decision-making and memory by warping the perception of past choices.
The clustering illusion is a cognitive bias where people perceive patterns in random or sparse data. This is categorized under 'Lack of meaning' and specifically within 'Stories in sparse data'. The human brain has a tendency to see clusters where none exist due to its pattern-recognition capabilities, often leading to misinterpretations of randomness.
Confirmation bias is a type of cognitive bias that involves favoring information that confirms previously existing beliefs or biases. This phenomenon occurs when people prefer information or interpret evidence in a way that is consistent with their own preconceptions, often ignoring or undervaluing contradictory data.
Congruence bias is a type of cognitive bias which occurs when individuals test a hypothesis by focusing primarily on evidence that directly supports it, rather than seeking out information which might disprove or challenge it. This bias emerges notably in environments where information is plentiful, prompting a preference for data that aligns with current beliefs, rather than a holistic examination.
The conjunction fallacy is a cognitive bias where individuals assume specific conditions are more probable than a single general one. This often occurs when people mistake the conjunction of two events as more likely than one of the events alone, violating the basic rule of probability.
Conservatism cognitive bias refers to the tendency of individuals to insufficiently revise their beliefs when presented with new evidence. This bias falls under the broader category of information overload, as people tend to give disproportionate weight to their prior knowledge or beliefs and do not adequately adjust them with fresh information. The phenomenon is closely associated with the psychological difficulty of abandoning previously held concepts and the innate preference for consistency.
The continued influence effect is a cognitive bias where people continue to maintain beliefs based on misinformation, even after it has been debunked. Despite corrections and factual information being presented, the initial misinformation persists in influencing beliefs and decisions.
Declinism is a cognitive bias characterized by a pessimistic belief that a society or an institution is inexorably declining or worsening. This perception often overlooks positive change and growth, focusing instead on nostalgia for a perceived better past. Declinism influences how individuals assess both current conditions and future prospects, often leading to an irrational emphasis on negative aspects over positive developments.
The Delmore effect is a cognitive bias where people prefer simple, complete solutions over complex ones.
The Dunning-Kruger effect is a cognitive bias wherein individuals with low ability, expertise, or experience in a particular domain overestimate their ability or knowledge. Conversely, experts often underestimate their competence. This bias was first identified by social psychologists David Dunning and Justin Kruger, based on their research published in 1999.
Duration neglect is a cognitive bias where the duration of an emotional experience has little impact on the overall retrospective evaluation of the event. Instead, the evaluation is disproportionately influenced by the peak (most extreme moment) and the end (final moment) of the experience.
Egocentric bias is a cognitive bias that leads individuals to rely heavily on their own perspective and experience when interpreting events and interactions with others. This bias can result in an overestimation of one’s contributions, influence, or knowledge in various situations.
Empathy gap is a cognitive bias where individuals tend to underestimate the influence of emotional states on their own and others' decision-making and behavior. This bias highlights the difficulty humans face in predicting behaviors and preferences in different states of mind, most notably between emotional and rational states.
Escalation of commitment refers to a cognitive bias where individuals or organizations continue to invest in a decision despite clear evidence that it may be failing or no longer viable. This phenomenon occurs when those involved irrationally persist in a course of action due to prior investments of time, money, or resources.
Essentialism is a cognitive bias where individuals believe that certain categories, such as people, animals, or objects, have an inherent essence that gives them their identity. This bias often leads to overgeneralization and stereotyping, as individuals attribute fixed traits to members of these categories.
Extrinsic incentive error is a cognitive bias where people tend to overestimate the influence of extrinsic incentives (such as money or rewards) on others' behaviors, while undervaluing intrinsic motivations (like personal satisfaction or enjoyment). It can lead to a misunderstanding of why people perform certain actions or participate in activities.
The false consensus effect is a cognitive bias where people overestimate the degree to which their beliefs, attitudes, and opinions are shared by others. This bias leads to an inflated sense of one's own norms and opinions, often overgeneralizing them as common or typical among a larger group or population.
The framing effect is a cognitive bias where individuals react differently depending on how information is presented, rather than the information itself. This bias is classified under information overload, particularly in the 'change is noticed' subcategory, which addresses how alterations in information presentation can lead to different perceptions and decisions.
The frequency illusion, also known as the Baader-Meinhof phenomenon, is a cognitive bias where after noticing something for the first time, there is a tendency to notice it more frequently, leading to a false belief that its frequency has increased. This bias is a component of information overload, specifically in the realm of repetition and memory recognition.
The fundamental attribution error is a cognitive bias that refers to the tendency of individuals to overemphasize personal characteristics and ignore situational factors in judging others' behavior. This bias often leads people to attribute others' actions to their inherent personalities while overlooking the influence of external circumstances.
Group attribution error is a cognitive bias in which individuals erroneously attribute the behaviors or characteristics of a group to all of its members, or vice versa. This bias stems from a tendency to generalize based on limited information, leading to misconceptions and stereotypes.
The Halo Effect is a cognitive bias where our overall impression of a person, brand, or product influences our feelings and thoughts about their specific traits. If we perceive someone or something positively in one area, we are likely to have a positive bias for their other characteristics as well.
Hindsight bias, also known as the 'knew-it-all-along' phenomenon, is a cognitive bias in which people perceive past events as having been more predictable than they actually were. After an event has occurred, individuals often believe they could have predicted or even foreseen the outcome, leading to an illusion of inevitability. This bias can affect memory and perception, resulting in a distorted understanding of the past.
Hyperbolic discounting is a cognitive bias where individuals tend to prefer smaller, immediate rewards over larger, delayed rewards. This bias reflects the human tendency to reduce the perceived value of delayed outcomes, often leading to choices that contradict long-term interests.
The Identifiable Victim Effect is a cognitive bias that refers to the tendency of individuals to offer greater aid when a specific, identifiable individual is observed under hardship, as opposed to a large, vaguely explained group with the same need. This bias demonstrates how humans are more emotionally moved and compelled to act when faced with a particular person's plight rather than statistical information or a broader context.
The illusion of control is a cognitive bias wherein individuals overestimate their influence over external events. This bias leads them to believe that they have the power to control outcomes that are largely determined by external factors or chance.
The illusion of validity is a cognitive bias that occurs when people overestimate their ability to interpret and predict outcomes in situations based on limited information. It is part of the broader category of cognitive biases related to our need for meaning, specifically within storytelling scenarios wherein sparse data is available. This bias leads individuals to have unwarranted confidence in their predictions or judgments, often overlooking the foundational issues of insufficient data or the complexity of the situations.
Illusory correlation is a cognitive bias that describes the tendency to perceive a relationship between two variables even when no such relationship exists. This bias is particularly likely to occur with low-frequency variables or when the data is sparse. It often leads individuals to form and maintain specific beliefs or stereotypes based on misleading or insufficient information.
Illusory superiority, often referred to as the above-average effect, is a cognitive bias whereby individuals overestimate their own qualities and abilities relative to others. This phenomena leads people to believe they are better than average in various domains, including intelligence, performance, and other competencies.
The illusory truth effect is a cognitive bias that describes how repeated exposure to information can lead to its perception as more truthful or accurate, regardless of its veracity. This phenomenon occurs because repetition makes statements easier to process, and this ease is often misattributed to truthfulness.
The implicit associations cognitive bias refers to the automatic associations some individuals hold about groups of people, ingrained at an unconscious level. These associations can influence attitudes, judgments, and behaviors, often without the individual being aware of them. This bias falls under the broader category of implicit stereotypes, which are the unconscious beliefs and attitudes toward particular groups based on race, gender, age, or other factors.
In-group bias, also known as in-group favoritism, is a cognitive bias where individuals tend to favor, support, and give preferential treatment to members of their own group over those in other groups. This bias is a fundamental aspect of human social interaction where familiar things and familiarity with the in-group lead to implicit positive associations, often regardless of objective evidence or actual differences among groups.
Information bias is a cognitive bias that compels individuals to seek more information in situations where it may be irrelevant or redundant. This bias stems from the need for speed in decision-making, preferring simple and complete narratives over complex and ambiguous ones. Despite the illusion of informed action it provides, it often leads to inefficiencies and poor decision-making.
Insensitivity to sample size is a cognitive bias where individuals, when evaluating statistical evidence, tend to disregard the size of the sample from which the evidence originates. This bias leads to overgeneralization from small samples and underestimation of variability based on sample size.
The Just-world hypothesis is a cognitive bias that leads individuals to believe that the world is inherently fair and that people ultimately get what they deserve. This belief can shape the way individuals perceive events and the behavior of others, often leading to a skewed interpretation of reality.
The Law of Triviality, also known as Parkinson's Law of Triviality, describes a phenomenon where people give disproportionate weight and time to trivial issues while neglecting more complex and critical matters. This cognitive bias leads to decision-makers focusing on simple tasks that are easy to understand and discuss, rather than tackling the more significant issues that require deeper analysis.
Leveling and sharpening cognitive biases refer to the processes by which individuals simplify complex information and emphasize certain elements over others. These biases illustrate how people tend to minimize or exaggerate details when recalling events or experiences, often leading to misrepresentation or distortion of the original information.
Loss aversion is a cognitive bias that refers to the tendency for individuals to prefer avoiding losses rather than acquiring equivalent gains. This phenomenon implies that the pain of losing is psychologically about twice as powerful as the pleasure of gaining. As such, people are typically more motivated to try to avoid losses than to try to achieve gains.
The mere exposure effect is a psychological phenomenon where people tend to develop a preference for things they are repeatedly exposed to. This cognitive bias suggests that familiarity with something can lead to affection, even if it was initially neutral or disinterested.
The misinformation effect is a cognitive bias that occurs when a person's memory of an event becomes less accurate due to the influence of post-event information. This phenomenon often leads to the creation of false memories and impacts an individual's ability to recall events as they actually occurred.
The Moral Credential Effect is a cognitive bias where an individual's prior ethical behavior gives them a license to engage in potentially unethical actions without feeling guilty or damaging their self-image. It occurs when having previously made a moral choice allows someone to feel less compelled to act morally in subsequent situations.
Murphy's Law is a popular adage that states, 'Anything that can go wrong, will go wrong.' Although initially considered just a humorous observation about life, it reveals cognitive biases in how humans perceive and interpret unlikely and unfavorable events.
Naïve cynicism is a cognitive bias where individuals tend to assume that others are more egocentric, biased, or motivated by self-interest than themselves. This bias reflects a skepticism towards others' intentions and a belief that their actions are driven by self-serving motives.
Naïve realism is a cognitive bias where individuals believe that they perceive the world objectively and that others who perceive it differently are uninformed, irrational, or biased. This bias leads to the assumption that one’s own interpretation of reality is the accurate one, while differing perspectives are flawed.
Negativity bias is a cognitive bias that leads individuals to give more significance and weight to negative experiences or information over positive or neutral ones. This bias manifests itself by disproportionately impacting decision-making and perception, often making negative experiences more influential than positive ones.
Neglect of probability is a cognitive bias where individuals disregard the probability of an event occurring and focus instead on the potential outcomes. This bias often leads to irrational decision-making because it prioritizes the emotional impact of potential outcomes over rational analysis of their likelihood. It is categorized under 'Lack of meaning' and is a subcategory of 'Stories in sparse data.'
Normalcy bias is a cognitive bias characterized by the refusal to plan for or react to a disaster which has never happened before. This bias leads individuals to underestimate both the likelihood of a disaster occurring and its potential impact, reinforcing a false sense of security.
The 'Not Invented Here' (NIH) bias refers to a cultural or psychological stance where individuals or organizations resist using, acquiring, or even acknowledging external knowledge, ideas, or solutions, simply because these innovations originate outside their own environment. This bias is characterized by the preference for internally developed products or ideas, often leading to skepticism and dismissal of externally sourced solutions.
Occam's Razor is a cognitive bias and philosophical principle that suggests that, among competing hypotheses that predict equally well, the one with the fewest assumptions should be selected. It promotes simplicity in decision-making and problem-solving, suggesting that simpler ideas with less complexity are often more likely to be correct.
Omission bias is a cognitive bias where individuals tend to judge harmful actions as worse or less morally acceptable than equally harmful omissions (inactions). In simple terms, people often believe that doing something harmful is worse than failing to prevent harm. This bias is a significant concern within the realm of decision-making and ethics, as it can lead to skewed perceptions and judgments.
Optimism bias is a cognitive bias that causes individuals to believe that they are less likely to experience negative events and more likely to experience positive ones compared to others. It's an inherent part of human psychology that can influence a wide range of decisions and behaviors, often leading to overly positive evaluations of future outcomes.
The Ostrich Effect is a cognitive bias that describes the tendency of individuals to avoid negative or threatening information by metaphorically burying their heads in the sand, akin to the behavior of an ostrich. The bias is named after the common (though incorrect) belief that ostriches hide from danger by burying their heads in the sand.
Out-group homogeneity bias is a cognitive phenomenon where people perceive members of a group to which they don't belong (the out-group) as more similar to one another than members of their own group (the in-group). This bias leads to the perception that 'they' are alike, while 'we' are diverse and varied.
Outcome bias is a cognitive bias that occurs when people judge the quality of a decision based on its outcome rather than the quality of the decision at the time it was made. This bias can lead to an inaccurate assessment of the decision-making process as it disregards the information available when the decision was made, focusing instead on the result.
The overconfidence effect is a well-documented cognitive bias in which a person's subjective confidence in their judgments is greater than the objective accuracy of those judgments. This phenomenon is prevalent across various domains of decision-making and has significant implications in both personal and professional settings.
The peak-end rule is a cognitive bias that impacts how people retrospectively evaluate experiences. According to this rule, individuals tend to judge experiences based largely on how they felt at the most intense point (the peak) and at the end, rather than on the total sum or average of every moment of the experience.
The picture superiority effect is a cognitive bias that suggests images and pictures are more likely to be remembered than words. This phenomenon indicates that when information is presented as both pictures and text, the visual representation tends to be retained more effectively in our memory.
Prejudice is a cognitive bias that involves forming an opinion or assumption about an individual or group based on generalizing characteristics, often discarding specific details in the process. This bias relies heavily on stereotypes and oversimplified beliefs about a group, resulting in assumptions that don't account for individual variations.
The primacy effect is a cognitive bias that results in a person recalling the first items in a series more strongly than the subsequent items. This effect is a part of the broader concept known as the 'serial position effect,' which examines how the position of an item in a list affects how well it is remembered.
Pro-innovation bias is a cognitive bias that occurs when an individual or group overvalues the benefits of a new product or innovation while underestimating its limitations and challenges. It leads people to favor new ideas and technologies, often without thoroughly examining their impact or potential drawbacks.
Projection bias is a cognitive bias that describes the human tendency to overestimate the degree to which their future preferences and tastes will align with their current preferences and tastes. This bias is a type of misforecasting that occurs when individuals assume that their emotional states and desires will remain unchanged over time.
The pseudocertainty effect is a cognitive bias that refers to individuals' tendency to make risk-averse choices when outcomes are framed as gains, and risk-seeking choices when they are framed as losses. This occurs despite the objective probabilities and outcomes remaining the same. The bias highlights how problem framing can significantly influence decision-making, particularly under conditions of uncertainty.
Reactance is a cognitive bias referring to the emotional reaction individuals have when they perceive their autonomy to be threatened or their range of options to be limited. This psychological response often leads to behavior that is contrary to what is being imposed, as an attempt to regain control or freedom. When people perceive their freedoms are being infringed upon, they may be motivated to restore those freedoms, even at the cost of making irrational decisions. This bias falls under the category 'Need for Speed' due to the immediate and instinctive nature of the response and the subcategory 'Motivated to preserve autonomy and status.'
Reactive devaluation is a cognitive bias where an individual devalues or dismisses proposals or ideas if they originate from an adversary or an opposing party, even if these ideas could be beneficial. This bias often stems from an emotional response, leading people to focus more on the source than the content, thereby affecting negotiations, decision-making, and conflict resolution.
The recency effect is a cognitive bias that refers to the tendency of individuals to better remember the most recently presented items or experiences. This bias is commonly observed when recalling items from a list or events that have just occurred, demonstrating that the most recent information tends to be more impactful on memory recall compared to earlier information.
The Rhyme as reason effect, also known as the 'Eaton-Rosen phenomenon,' is a cognitive bias where people perceive rhyming statements as more truthful or accurate compared to non-rhyming equivalents. This effect capitalizes on the human inclination towards simple, complete phrases over complex or ambiguous ones, suggesting that a statement's form can significantly influence its perceived truthfulness.
Rosy retrospection is a cognitive bias that leads people to perceive past events as more favorable than they actually were. Individuals often remember the past with idealized positivity, overlooking negative aspects and enhancing positive ones. This bias influences how memories are recalled and interpreted, often painting a 'rosier' picture of the past than what the reality might have been.
Selective perception is a cognitive bias that involves focusing on information that confirms existing beliefs while ignoring information that contradicts them. This phenomenon falls under the category of Information overload, where individuals are faced with vast amounts of data and selectively filter it, often unconsciously, leading to reinforcement of pre-existing notions.
The self-relevance effect, a cognitive bias, is the tendency for individuals to better remember information that relates to themselves than information that has less personal relevance. This bias fundamentally affects how we process and prioritize the vast amount of information we encounter daily, making personally relevant information particularly salient.
Self-serving bias is a common cognitive bias that refers to an individual's tendency to attribute their successes to internal or personal factors while blaming external factors for any failures. This bias is part of the broader category of the need for speed in cognitive processing and falls under doing what matters in self-assessment and perception.
The Semmelweis reflex is a cognitive bias wherein people tend to reject new evidence or knowledge if it contradicts established norms or beliefs. Named after Ignaz Semmelweis, a 19th-century Hungarian physician who discovered that hand-washing could drastically reduce childbed fever incidence, the term describes the tendency to dismiss or undervalue findings that conflict with accepted paradigms.
Social desirability bias is a cognitive bias where individuals tend to answer questions or behave in ways they perceive as being more socially acceptable, rather than being truthful or authentic. This often results in skewed data in surveys, interviews, and research, as people provide responses they believe will make them look favorable in the eyes of others.
Status quo bias is a cognitive bias that refers to the preference for the current state of affairs. Individuals exhibiting this bias favor decisions or policies that maintain things as they are, rejecting changes even when those changes might lead to better outcomes. This bias is often influenced by a need to preserve autonomy and maintain one's current status.
Stereotyping is a cognitive bias where generalized beliefs or assumptions are made about members of a particular group. This bias often arises from information gaps, leading individuals to substitute specific knowledge about a person with generalized group characteristics.
The subadditivity effect is a cognitive bias where individuals tend to judge the probability of a whole as less than the sum of its parts. In essence, people often underestimate the total probability of an event when it is broken down into component parts. This effect is prominent within the realm of probabilistic reasoning, where human intuition struggles to accurately assess combined probabilities.
Subjective validation, also known as the Forer effect, is a cognitive bias whereby people tend to perceive vague or general statements as highly accurate and applicable to themselves personally. This phenomenon explains why individuals often find personal meaning in ambiguous information, such as horoscopes or personality tests, which seem tailor-made for them but are, in reality, generalized.
The sunk cost fallacy is a cognitive bias where individuals make decisions based on previously invested resources (time, money, effort) rather than the present and future value of their decision. This often leads to irrational decision-making as people continue to commit to a course of action due to the costs already incurred, which cannot be recovered.
Survivorship bias is a cognitive bias that occurs when an analysis only considers the 'survivors' or successful entities of a group while overlooking the failures, thereby skewing the results and leading to erroneous conclusions. This bias stems from the human tendency to draw inferences based on incomplete data, largely due to the absence of information about non-survivors.
The third-person effect is a cognitive bias where individuals believe that other people are more affected by media messages than they are themselves. This perception can lead people to overestimate the influence of media on others while underestimating its effect on themselves.
Ultimate attribution error is a cognitive bias that leads to the systematic attribution of behaviors of individuals or groups based on perceived inherent characteristics, especially in cases involving in-group versus out-group dynamics. This often results in attributing positive actions of in-group members to inherent traits and negative actions to situational factors, while interpreting out-group members' positive behaviors as situational and negative behaviors as inherent.
Zero sum bias is a cognitive bias where individuals perceive a situation as having a fixed amount of resources or benefits, leading them to think that one person's gain is inherently another's loss. This misperception often overlooks the possibility of non-zero-sum scenarios where all parties can benefit.
