Serial Position Effect

Exploiting the tendency to remember items at the beginning and end of a list better than those in the middle.

Affect Heuristic

Exploiting the tendency for current emotions to override rational assessment of risks and benefits.

Spotlight Effect Exploitation

Leveraging someone's overestimation of how much others notice and judge them.

Dunbar Number Exploitation

Exploiting the cognitive limit on the number of meaningful relationships a person can maintain (roughly 150).

Good Cop/Bad Cop

A two-person negotiation tactic where one person is hostile and one is sympathetic, creating pressure to accept the "reasonable" person's terms.

Highball/Lowball

Opening with an extreme offer to anchor the negotiation range in your favor.

Nibbling

Asking for small additional concessions after the main deal is already agreed, exploiting the other party's desire to close and avoid reopening negotiations.

Fait Accompli

Taking action unilaterally and presenting the result as irreversible, forcing the other party to accept a new reality rather than negotiating it.

Brinkmanship

Pushing a negotiation to the edge of breakdown — threatening to walk away, set deadlines, or escalate — to force concessions through fear of failure.

Salami Tactics

Achieving a large objective through a series of small, incremental actions, each too minor to provoke resistance on its own.

Bogey Technique

Pretending that an issue you don't care about is very important to you, then "conceding" it in exchange for something you actually want.

The Flinch

Reacting with visible shock or dismay to an offer to make the other party immediately doubt their position and offer concessions.

Deadline Pressure

Imposing real or artificial deadlines to force hasty decisions, preventing careful evaluation of terms.

Authority Limits Ploy

Claiming you lack authority to make a decision, forcing the other party to make concessions before you "check with" a higher authority who demands more.

Take It or Leave It

Presenting an offer as final and non-negotiable to force acceptance or walk-away, eliminating the possibility of further concessions.

Exploding Offer

Making an attractive offer with an extremely short acceptance window, preventing the recipient from exploring alternatives.

Patience as Weapon

Using superior time tolerance to outlast the other party, who eventually concedes due to fatigue, deadlines, or the cost of continued negotiation.

Split the Difference Trap

Proposing to "meet in the middle" after anchoring at an extreme position, so the "middle" actually favors you significantly.

Endowment Effect Exploitation

Exploiting the tendency for people to overvalue things they already possess, making it psychologically costly to give them up.

Status Quo Bias Exploitation

Designing systems where the default option benefits the designer, exploiting people's tendency to stick with whatever is pre-selected.

Hyperbolic Discounting Exploitation

Exploiting the human tendency to prefer smaller immediate rewards over larger future ones — making short-term gratification feel rational.

Mental Accounting Manipulation

Exploiting the tendency to treat money differently depending on its mental category — "found money," "vacation budget," "bonus" — rather than treating all money as fungible.

Prospect Theory Applications

Exploiting Kahneman and Tversky's finding that people feel losses roughly twice as strongly as equivalent gains, systematically framing choices in terms of loss.

Fundamental Attribution Error

The tendency to explain other people's behavior by their character and dispositions while underweighting the situation they were in — even when the situation plainly produced the behavior.

Hindsight Bias

Once an outcome is known, people overestimate how predictable it was and misremember their own earlier uncertainty — the “I knew it all along” effect.

Outcome Bias

Judging the quality of a decision by how it turned out rather than by whether it was sound given what was known when it was made.

Optimism Bias

The tendency to believe one's own future will be better than the evidence and base rates justify — good events more likely, bad events less likely, for oneself than for comparable others.

Planning Fallacy

The systematic tendency to underestimate the time, cost, and risk of a project while overestimating its benefits — even by people who know that their past projects overran.

The tendency to believe one can influence outcomes that are actually determined by chance, especially when the situation carries the trappings of skill — choice, familiarity, involvement, competition.

Just-World Hypothesis

The need to believe that the world is fundamentally fair — that people get what they deserve — which leads observers to conclude that those who suffer must have deserved it.

System Justification

A motivation to defend, rationalize, and see as legitimate the social, economic, and political arrangements one lives under — sometimes even when those arrangements work against one's own interests.

Belief Perseverance

The persistence of a belief after the evidence that created it has been fully discredited — because the explanation people built around the belief survives the loss of the original data.

Continued Influence Effect

A specific piece of information keeps shaping people's reasoning after it has been clearly retracted — even when they remember the retraction and say they accept it.

Illusory Correlation

Perceiving a relationship between two things that are not actually related, or perceiving a much stronger relationship than exists — typically because both items are distinctive or because the relationship was expected.

Negativity Bias

Negative events, information, and impressions carry more weight, draw more attention, and persist longer in memory than positive ones of equal magnitude.

IKEA Effect

The tendency to value things more highly because one helped make them — a disproportionate attachment to the products of one's own labor, largely independent of their quality.

Omission Bias

The tendency to judge harmful actions as worse, and more blameworthy, than equally or more harmful inactions — so that doing nothing feels safer even when it is not.

Zero-Risk Bias

A preference for reducing a small risk all the way to zero over reducing a larger risk by a greater amount — the pull of certainty over expected value.

Denomination Effect

People are less likely to spend a given sum when it is held as a single large bill than when the same amount is held in smaller bills, coins, or tokens.

Money Illusion

The tendency to think about money in nominal terms — face-value dollars — rather than in real terms of what it buys, so that inflation and deflation distort judgments of raises, prices, gains, and losses.

Hot-Cold Empathy Gap

The failure to appreciate how much a visceral state — hunger, fear, arousal, craving, anger, pain — changes preferences and behavior: calm people underestimate what they will do when hot, and hot people cannot imagine being calm again.

Curse of Knowledge

Once you know something, you cannot fully imagine not knowing it — so the informed systematically overestimate what others know, how clear their own message is, and how obvious a conclusion was.

False Consensus Effect

The tendency to overestimate how widely one's own beliefs, preferences, and behaviors are shared — to see one's own position as common and appropriate, and disagreement as rarer and stranger than it is.

Naive Realism

The conviction that one sees the world as it objectively is, so that reasonable people given the same facts would agree — and those who do not must be uninformed, irrational, or biased.

Illusion of Transparency

The tendency to overestimate how visible one's internal states — nervousness, disgust, deception, disagreement — are to observers, because one's own experience of them is so vivid.

Reactive Devaluation

The tendency to rate a proposal as less attractive simply because it came from an adversary or counterpart — the same terms are devalued when the other side offers them.

Semmelweis Reflex

The reflexive rejection of new evidence because it contradicts established norms, beliefs, or paradigms — and, under the same name, the rhetorical exploitation of that story by anyone whose claim has been rejected.

Barnum Effect

The tendency to accept vague, general personality statements as uniquely accurate descriptions of oneself — especially when they are flattering and presented as the result of individual analysis.

Cold Reading

A set of techniques for appearing to know intimate facts about a stranger with no prior information, by combining high-probability statements, observation, and the subject's own feedback — presented as psychic, intuitive, or expert insight.

Hot Reading

Presenting information gathered in advance about a person — from research, informants, intake forms, overheard conversation, or social media — as if it had been obtained by psychic, intuitive, or expert means.

Apophenia

The tendency to perceive meaningful patterns, connections, and intentions in random or unrelated data — faces in clouds, messages in noise, plots in coincidence.

Frequency Illusion

After you learn or notice something new, it seems to appear everywhere — a product of selective attention and confirmation bias, not of any change in the world.

Rosy Retrospection

The tendency to remember past events as more pleasant than they were experienced at the time — and to anticipate future ones more rosily than they will be — because the minor irritations fade and the highlights remain.

Declinism

The belief that a society, culture, or institution is in decline from a better past — a predisposition that persists across eras and is largely independent of the measured trends.

Identifiable Victim Effect

People respond far more strongly — with money, attention, and political will — to a single identified person in need than to statistics describing many more people in the same need.

Scope Insensitivity

The failure of valuations, emotions, and willingness to pay to scale with the size of a problem — two thousand, twenty thousand, and two hundred thousand affected can feel, and be valued, almost the same.

Proportionality Bias

The intuition that big events must have big causes — so that a major outcome produced by a small, mundane, or accidental cause feels unexplained, and a conspiracy or grand design feels more plausible than the evidence warrants.

Fear Conditioning Exploitation

Pairing a person, group, product, or idea with a threat cue often enough that the target itself comes to trigger a defensive response, so the audience reacts to it before evaluating it.

Reward Prediction Error

The dopamine signal that fires when an outcome is better than expected and falls silent when it is exactly as expected. Anything that delivers rewards unpredictably keeps the signal alive, which is why uncertain payoffs hold attention far longer than reliable ones.

Oxytocin and In-Group Trust

The claim that a hormone makes people trusting, and the sturdier finding underneath it: cues of shared group membership lower vigilance toward insiders and can raise hostility toward outsiders. Trust built through belonging is the lever; the “moral molecule” is the overclaim.

Stress-Narrowed Cognition

Under acute stress, attention narrows to the most salient cue, working memory shrinks, and control shifts from deliberate prefrontal circuits to fast habitual ones — a state in which a person weighs fewer options and is easier to steer.

Sleep-Deprivation Suggestibility

Keeping a person awake — through long sessions, late-night calls, all-night programs, or interrogation — until reduced prefrontal function makes them more compliant, more suggestible, and less able to weigh what they are agreeing to.

HALT Vulnerability States

Timing an ask for when the target is Hungry, Angry, Lonely, or Tired — the recovery-community HALT checklist — because each state predictably lowers self-control and widens the gap between what a person will agree to now and what they would agree to fed and rested.

Orienting Response Exploitation

Triggering the involuntary “what is it?” reflex — with sudden sound, motion, cuts, flashes, or novelty — so that attention is captured before any decision to attend has been made.

Attention Capture by Faces and Motion

Using faces, direct or averted gaze, and sudden motion — the stimulus classes the visual system prioritizes without instruction — to steer where people look, and therefore what they process, before they decide to look at anything.

Habituation and Escalation

The decline in response to a repeated stimulus, and the persuader's answer to it: escalate the intensity, shock, or novelty of each message to recover the reaction — or, in reverse, introduce each step so gradually that no single change triggers a response.

Post-Hoc Rationalization Exploitation

Engineering a behavior or choice first and letting the person supply the reasons afterward — exploiting the mind's tendency to generate confident explanations for actions whose real causes it cannot see.

Nocebo Framing

Framing information so that the expectation of harm produces the harm — real symptoms, worse pain, side effects from inert treatments — and using that expectation to sell a remedy, discredit a rival, or spread alarm.

Placebo Framing

Using price, branding, ritual, and confident presentation to raise expectations of benefit — which measurably improves subjective outcomes — and then selling the expectation as if it were the product's active ingredient.

Mirror-Neuron Claims

Invoking mirror neurons — cells that fire both when an animal acts and when it watches the same act — to claim that audiences automatically feel, understand, or imitate what a speaker, brand, or story presents. The cells are real; most of the claims built on them are not.

Identity-Protective Cognition

The motivated processing of evidence to protect one's standing in a group whose identity is bound up with a position — so that facts threatening the group are scrutinized, discounted, or reinterpreted, while facts supporting it are waved through.

Cultural Cognition

The tendency to fit perceptions of risk and fact to the values of one's cultural group — hierarchical or egalitarian, individualist or communitarian — and the persuasion practice built on it: choosing messengers and frames that match the audience's worldview so the message gets through.

Coalitional Psychology

The evolved machinery for tracking who is on whose side — detecting alliances, sorting people into us and them on minimal cues, and shifting trust, generosity, and moral concern along those lines — which persuaders activate by defining a coalition and pointing it at an enemy.

Cheater-Detection Exploitation

Triggering the mind's specialized sensitivity to people who take a benefit without paying the cost — by casting a group, a rival, or an institution as free-riders or cheats — to recruit punitive anger that bypasses evaluation of the actual facts.

Status-Seeking Exploitation

Selling status — rank, prestige, being seen to be ahead — or selling relief from status anxiety, to a species in which the desire for standing is a fundamental motive that operates whether or not the standing is real.

Reputation Threat

Using the fear of what others will think — exposure, embarrassment, loss of standing — to compel behavior, from watching-eyes cues and public commitment to blackmail; the lever works because humans monitor their reputations constantly and often below awareness.

Dark Triad Manipulation

The interpersonal tactics characteristic of people high in narcissism, Machiavellianism, and subclinical psychopathy — charm, exploitation, strategic deceit, and low empathy — and the pattern by which they get their way. The traits are dimensional, and the label is a description, not a diagnosis.

Machiavellianism

A strategic, cynical orientation to other people — treating them as instruments, telling them what they want to hear, and keeping emotional distance — first measured by Christie and Geis in 1970 and named for the author of The Prince.

Need-for-Closure Exploitation

Supplying certainty — a simple answer, a clear villain, a firm deadline — to people whose need to resolve ambiguity has been raised by fatigue, noise, threat, or time pressure, so that the first confident account is seized and frozen before alternatives are considered.

Need-for-Cognition Targeting

Tailoring a message to how much the audience enjoys thinking — arguments and evidence for those who do, cues and slogans for those who do not, and imitation evidence for the thinkers who will not check — so that persuasion runs through whichever route the target is least likely to scrutinize.

Authoritarian Dynamic Activation

Raising the perception that the group's norms, unity, or order are under threat in order to activate, in the roughly third of any population predisposed to it, a demand for conformity, sameness, and punishment of deviants — a dynamic that runs on threat, not on party.

Trauma Reenactment Exploitation

Identifying a person's history of abuse or neglect and reproducing its familiar dynamics — intermittent warmth, control, unpredictability — because patterns learned early feel like love or safety and are hard to see from inside them.

Novelty-Seeking Exploitation

Exploiting the brain's preferential response to new stimuli — and the individual differences in how strongly people crave them — by manufacturing novelty: “new” labels, curiosity gaps, constant feed refresh, and product cycles that reward the next thing over the better thing.

Mere Urgency Effect

The tendency to choose a task or offer because it feels urgent rather than because it matters — preferring the smaller reward with the shorter window over the larger one without a deadline — which persuaders exploit by attaching artificial time limits to whatever they want chosen.

Ostracism Threat

Using the threat of being excluded, ignored, or cast out — the silent treatment, shunning, deplatforming, “nobody will speak to you” — to compel conformity or compliance, drawing on a need to belong so basic that even exclusion by strangers or computers hurts.

Contrast Effect

A judgment about one thing shifts depending on what was presented just before or beside it: the same price, person, or offer looks better after something worse and worse after something better.

Unit Bias

People treat whatever is presented as a single unit — one plate, one bottle, one bundle, one “serving” — as the appropriate amount to consume or accept, regardless of its actual size.

Von Restorff Effect

An item that differs from its surroundings — in colour, size, category, or format — is remembered far better than items that blend in, and the isolated item also pulls attention and memory away from its neighbours.

Misinformation Effect

Information encountered after an event — a leading question, a co-witness's account, a news report — becomes incorporated into memory of the event itself, so that people sincerely remember details they never saw.

Source Confusion

Memory for a claim outlasts memory for where the claim came from, so information from an unreliable, biased, or explicitly discredited source is later recalled as simply something one knows.

Sleeper Effect

A persuasive message from a low-credibility source, or one accompanied by a discounting cue, can become more persuasive over time as the cue is forgotten faster than the message.

Illusion of Explanatory Depth

People believe they understand how things work — zippers, toilets, tariffs, sanctions — far better than they do, and the illusion collapses only when they are asked to produce the actual mechanism step by step.

Overconfidence Effect

People's subjective confidence in their judgments systematically exceeds their accuracy, and audiences reward displayed confidence as if it were evidence of competence.

Choice-Supportive Bias

After making a choice, people remember the option they picked as having had more good features, and the option they rejected as having had more bad ones, than either actually had — memory is rewritten to flatter the decision.

Social Desirability Bias

People answer questions and make public choices in the way that will be approved of rather than the way that is true — over-reporting virtue and under-reporting vice — and anyone who controls the question or the audience can steer the answer.

Outgroup Homogeneity

Members of groups one does not belong to are perceived as more alike — in opinions, traits and appearance — than members of one's own group, so a single outgroup member is readily taken as typical of all of them.

Stereotype Activation

A cue — a name, a face, a word, a neighbourhood, an accent — brings a group stereotype to mind automatically, and the activated stereotype shapes judgment of the individual or the issue unless the perceiver has the motive, time and awareness to override it.

Mortality Salience

Reminders of death are placed near a request — for a vote, a donation, a purchase, a conversion — on the theory that people who have just been reminded of their mortality cling harder to their worldview, punish outsiders, and favour strong leaders and the familiar.

Ego Depletion

The claim that self-control draws on a single limited resource that runs down with use, so that people who have already resisted, decided or concentrated will give in more easily — and the widespread persuasion practice of wearing people down that rests on it.

Automation Bias

People over-trust the output of automated systems — following a machine's recommendation against contrary evidence and failing to catch what the machine missed — and persuaders borrow that trust by wrapping human claims in the language of computation.

Ambiguity Effect

Given a choice, people avoid options whose probabilities are unknown in favour of options whose probabilities are known, even at a cost in expected value — so whoever can make a rival option feel unknowable, or their own feel measured, wins by default.

Information Bias

People seek and value information even when no possible result could change what they will do — and persuaders use the appetite either to delay action (“more research is needed”) or to manufacture a feeling of diligence around a decision the information cannot inform.
