1 Belief, Decision-making and Behavioral Flashcards
Action bias
The tendency for someone to act when faced with a problem even when inaction would be more effective, or to act when no evident problem exists.
Additive bias
The tendency to solve problems through addition, even when subtraction is a better approach.
Agent detection
The inclination to presume the purposeful intervention of a sentient or intelligent agent.
Ambiguity effect
The tendency to avoid options for which the probability of a favorable outcome is unknown.
Anchoring
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).
Anthropocentric thinking
The tendency to use human analogies as a basis for reasoning about other, less familiar, biological phenomena.
Anthropomorphism
The tendency to characterize animals, objects, and abstract concepts as possessing human-like traits, emotions, and intentions. The opposite bias, of not attributing feelings or thoughts to another person, is dehumanized perception, a type of objectification.
Attentional bias
The tendency of perception to be affected by recurring thoughts.
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
The tendency to depend excessively on automated systems which can lead to erroneous automated information overriding correct decisions.
Availability heuristic
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.
Backfire effect
The reaction to disconfirming evidence by strengthening one’s previous beliefs.
Base rate fallacy
The tendency to ignore general information and focus on information only pertaining to the specific case, even when the general information is more important.
Belief bias
An effect where someone’s evaluation of the logical strength of an argument is biased by the believability of the conclusion.
Berkson’s paradox
The tendency to misinterpret statistical experiments involving conditional probabilities.
Clustering illusion
The tendency to overestimate the importance of small runs, streaks, or clusters in large samples of random data (that is, seeing phantom patterns).
Common source bias
The tendency to combine or compare research studies from the same source, or from sources that use the same methodologies or data.
Compassion fade
The predisposition to behave more compassionately towards a small number of identifiable victims than to a large number of anonymous ones.
Confirmation bias
The tendency to search for, interpret, focus on and remember information in a way that confirms one’s preconceptions.
Congruence bias
The tendency to test hypotheses exclusively through direct testing, instead of testing possible alternative hypotheses.
Conjunction fallacy
The tendency to assume that specific conditions are more probable than a more general version of those same conditions.
Conservatism bias
The tendency to revise one’s belief insufficiently when presented with new evidence.
Continued influence effect
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.
Contrast effect
The enhancement or reduction of a certain stimulus’ perception when compared with a recently observed, contrasting object.

The predisposition to view the past favorably and future negatively
Decoy effect
Preferences for either option A or B change in favor of option B when option C is presented, which is completely dominated by option B (inferior in all respects) and partially dominated by option A.
Default effect
When given a choice between several options, the tendency to favor the default one.
Denomination effect
The tendency to spend more money when it is denominated in small amounts (e.g., coins) rather than large amounts (e.g., bills).

Exaggerated expectation
The tendency to expect or predict more extreme outcomes than those outcomes that actually happen.
Experimenter’s or
expectation 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.
Forer effect or
Barnum effect
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.
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.
Framing effect
Drawing different conclusions from the same information, depending on how that information is presented.
Frequency illusion or
Baader–Meinhof phenomenon
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).[51] 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.

Hungry judge effect
Judicial decision making and mood may be affected by physiological factors such as what the judge had for breakfast.
Hyperbolic discounting
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.
IKEA effect
The tendency for people to place a disproportionately high value on objects that they partially assembled themselves, such as furniture from IKEA, regardless of the quality of the end product.

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
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
The tendency to prefer a smaller set to a larger set judged separately, but not jointly.
Loss aversion
The perceived disutility of giving up an object is greater than the utility associated with acquiring it.[
Mere exposure effect
The tendency to express undue liking for things merely because of familiarity with them.
Money illusion
The tendency to concentrate on the nominal value (face value) of money rather than its value in terms of purchasing power.
Moral credential effect
Occurs when someone who does something good gives themselves permission to be less good in the future.
Neglect of probability
The tendency to completely disregard probability when making a decision under uncertainty.
Non-adaptive choice switching
After experiencing a bad outcome with a decision problem, the tendency to avoid the choice previously made when faced with the same decision problem again, even though the choice was optimal. Also known as “once bitten, twice shy” or “hot stove effect”.

Pessimism bias
The tendency for some people, especially those suffering from depression, to overestimate the likelihood of negative things happening to them.
Plan continuation bias
Failure to recognize that the original plan of action is no longer appropriate for a changing situation or for a situation that is different than anticipated.
Planning fallacy
The tendency to underestimate one’s own task-completion times.
Planning fallacy
The tendency to underestimate one’s own task-completion times.
Present bias
The tendency of people to give stronger weight to payoffs that are closer to the present time when considering trade-offs between two future moments.
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.
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.
Probability matching
Sub-optimal matching of the probability of choices with the probability of reward in a random context.
Pro-innovation bias
The tendency to have an excessive optimism towards an invention or innovation’s usefulness throughout society, while often failing to identify its limitations and weaknesses.

The tendency to be insensitive to the size of a problem when evaluating it. For example, being willing to pay as much to save 2,000 children or 20,000 children
Selection bias
Happens when the members of a statistical sample are not chosen completely at random, which leads to the sample not being representative of the population.
