Cognitive Biases

Information Processing Biases

Confirmation Bias: The tendency to search for, interpret, and recall information in a way that confirms one's preexisting beliefs or hypotheses, while giving disproportionately less consideration to alternative possibilities.
Availability Heuristic: Overestimating the likelihood of events based on their availability in memory, often influenced by recent exposure or emotional impact.
Anchoring Bias: Relying too heavily on the first piece of information encountered (the "anchor") when making decisions, leading to insufficient adjustment away from that initial reference point.
Framing Effect: Drawing different conclusions based on how the same information is presented, rather than solely on the information itself.
Information Bias: The tendency to seek additional information even when it does not affect action, leading to analysis paralysis.
Clustering Illusion: Perceiving patterns or clusters in random data, leading to the false belief that events are related when they are not.
Focusing Effect: Placing too much importance on one aspect of an event, which can skew overall perception and judgment.

Memory Biases

Hindsight Bias ("I-knew-it-all-along"): The inclination to see events as having been predictable after they have already occurred, which can distort one's memory of previous predictions or beliefs.
Rosy Retrospection: Remembering past events more fondly than they might have actually been experienced, leading to an overly positive recollection of the past.
Choice-Supportive Bias: Remembering one's past choices as better than they actually were, which can reinforce existing decisions despite contrary evidence.
Serial Position Effect: The tendency to recall the first and last items in a series more easily than those in the middle.
False Memory Effect: Recalling events that did not actually occur or remembering them differently from the way they happened.
Reminiscence Bump: Better recall of events that occurred during young adulthood compared to other periods in life.
Generation Effect: Enhanced memory for information that has been generated from one's own mind rather than simply read.

Social Biases

In-Group Favoritism: Favoring members of one's own group over those in other groups, leading to biased judgments and behaviors.
Out-Group Homogeneity Bias: Perceiving members of out-groups as more similar to each other than they actually are, which oversimplifies the diversity within those groups.
Halo Effect: Allowing one positive characteristic of a person to influence overall judgments about them, often leading to overestimation of other unrelated traits.
Horn Effect: Letting one negative characteristic of a person influence overall judgments about them, often leading to underestimation of other unrelated traits.
Fundamental Attribution Error: Overemphasizing personality-based explanations for behaviors observed in others while underemphasizing situational explanations.
Self-Serving Bias: Attributing positive events to one's own character but attributing negative events to external factors beyond one's control.
False Consensus Effect: Overestimating the extent to which others share one's beliefs, values, or behaviors.
Projection Bias: Assuming that others share the same thoughts, feelings, or values as oneself, without evidence.
Group Attribution Error: Misattributing the behaviors or characteristics of individual group members to the group as a whole.
Authority Bias: Valuing the opinions of authority figures more highly than others, regardless of the actual content of their opinions.
Sympathy Bias: Letting sympathetic feelings toward someone influence judgments about their actions or character.

Decision-Making Biases

Loss Aversion: Preferencing the avoidance of losses over the acquisition of equivalent gains, making individuals more sensitive to potential losses than to gains.
Sunk Cost Fallacy: Continuing an endeavor due to previously invested resources (time, money, effort), despite new evidence suggesting that the cost of continuing outweighs the benefits.
Endowment Effect: Valuing something more highly simply because one owns it, leading to an unwillingness to part with possessions at a fair price.
Overconfidence Bias: Overestimating one's own abilities, knowledge, or predictions, leading to increased risk-taking and potential errors in judgment.
Status Quo Bias: Preferring the current state of affairs and resisting change, even when alternative options may be more beneficial.
Choice-Supportive Bias: Enhancing the memory of choices made and perceiving them as better than they actually were, to reduce post-decision dissonance.
Hyperbolic Discounting: Preferring smaller, immediate rewards over larger, delayed rewards, which can lead to impulsive decisions.
Outcome Bias: Judging a decision based on its outcome rather than the quality of the decision at the time it was made.
Zero-Risk Bias: Preferring the complete elimination of small risks over the reduction of larger risks, even when the latter would result in greater overall risk reduction.
Escalation of Commitment: Increasing investment in a decision despite new evidence suggesting that the decision was wrong, often due to a desire to avoid admitting failure.
Optimism Bias: Overestimating the probability of positive outcomes and underestimating the probability of negative outcomes.
Pessimism Bias: Overestimating the probability of negative outcomes and underestimating the probability of positive outcomes.

Probability and Risk Biases

Gambler's Fallacy: Believing that past random events affect the likelihood of future random events, such as expecting a roulette wheel to land on red after several black outcomes.
Hot-Hand Fallacy: Believing that a person who has experienced success with a random event has a greater chance of further success in additional attempts.
Base Rate Neglect: Ignoring statistical information (base rates) in favor of specific information, leading to skewed probability assessments.
Neglect of Probability: Disregarding the probability of events when making decisions under uncertainty, often leading to poor risk assessment.
Zero-Risk Bias: Preferring to eliminate a small risk entirely rather than reducing a larger risk by a greater amount.
Risk Compensation: Adjusting one's behavior in response to the perceived level of risk, often becoming less cautious when safety measures are in place.

Attention and Perception Biases

Selective Perception: Allowing expectations to influence perception, causing individuals to focus on information that confirms their beliefs while ignoring contradictory information.
Inattentional Blindness: Failing to notice an unexpected stimulus in plain sight because attention is engaged on another task, event, or object.
Change Blindness: Failing to notice significant changes in a visual scene, highlighting limitations in visual memory and attention.
Illusory Correlation: Perceiving a relationship between variables (typically people, events, or behaviors) even when no such relationship exists.
Pareidolia: Perceiving meaningful patterns or connections in random or meaningless data, such as seeing faces in inanimate objects.

Emotional Biases

Affect Heuristic: Making decisions based on emotions rather than objective analysis, often leading to skewed risk assessments.
Empathy Gap: Underestimating the influence of emotional states on one's own or others' behavior, leading to misjudgments in decision-making.
Optimism Bias: Overestimating the likelihood of positive outcomes and underestimating the likelihood of negative ones, influenced by a generally positive emotional state.
Pessimism Bias: Overestimating the likelihood of negative outcomes and underestimating the likelihood of positive ones, influenced by a generally negative emotional state.

Belief and Reasoning Biases

Dunning-Kruger Effect: The tendency for individuals with low ability or knowledge in a particular area to overestimate their own ability, while those with high ability may underestimate their competence.
Backfire Effect: Strengthening one's belief in a misconception when confronted with contradictory evidence, rather than abandoning the belief.
Authority Bias: Valuing the opinions of authority figures more highly than others, regardless of the actual content, leading to skewed judgments and decisions.
Bandwagon Effect: Adopting beliefs or behaviors because many others are doing so, often leading to herd mentality and social conformity.
Belief Bias: Evaluating the strength of an argument based on the plausibility of its conclusion rather than the logical validity of its premises.

Other Cognitive Biases

Illusion of Control: Overestimating one's ability to control events, leading to increased risk-taking and misjudgment of situations.
Magical Thinking: Belief that one's thoughts, actions, or rituals can influence unrelated outcomes, often leading to superstitious behavior.
Recency Bias: Giving more weight to recent events or information over older data, affecting memory and decision-making.
Primacy Effect: Remembering the first items in a series better than those in the middle or end, influencing judgments and decisions.
Negativity Bias: Giving more weight to negative experiences or information than positive ones, affecting perceptions and reactions.
Mood-Congruent Memory Bias: Recalling memories that match one's current mood, leading to selective memory retention.
