Transparency – List of Manipulations and Cognitive Biases

Manipulation Techniques & Psychological Influence Tactics

1. Door-in-the-Face: Make a large request expected to be rejected, then follow with a smaller, more reasonable request that is more likely to be accepted.
2. Hoovering: Attempting to "suck back in" a former partner or associate through flattery, guilt, or false promises after a breakup or conflict.
3. Zeigarnik Effect: Incomplete or interrupted tasks are remembered better than completed ones, creating psychological tension that can be leveraged to maintain engagement.
4. Scarcity Principle: Creating perceived scarcity (limited time, quantity, or access) to increase perceived value and urgency.
5. Placebo Effect: A beneficial outcome produced by an inert treatment due to the recipient’s belief in its efficacy. (Note: This is a psychological phenomenon, not inherently manipulative unless exploited.)
6. Framing Effect: Presenting identical options in different ways (e.g., “90% fat-free” vs. “10% fat”) to influence decisions.
7. Exploiting Emotional Contagion: Deliberately expressing or amplifying emotions to influence others’ moods and decisions (e.g., feigning distress to gain compliance).
8. Mirroring: Subtly imitating another’s posture, speech, or gestures to build rapport and trust—often used in sales or interrogation.
9. Divide and Conquer: Sowing discord within a group to weaken collective resistance and increase individual susceptibility to control.
10. Loss Aversion: Emphasizing potential losses (rather than gains) to drive decisions, as losses psychologically weigh ~2x more than equivalent gains.
11. Priming: Exposing someone to subtle cues (words, images, contexts) that unconsciously influence later behavior or judgment.
12. Power of Touch: Brief, appropriate touch (e.g., on the arm) can increase likability, trust, and compliance.
13. Halo Effect: Assuming that because someone excels in one area (e.g., looks, charisma), they must be competent or virtuous in others.
14. Low-Balling: Securing agreement to a deal, then changing the terms (e.g., raising the price) after commitment has been made.
15. Cognitive Dissonance Exploitation: Creating inconsistency between beliefs and actions to pressure someone into changing their stance to restore psychological comfort.
16. Inducing Groupthink: Suppressing dissent in groups through pressure, isolation, or leadership dominance to enforce conformity.
17. Confirmation Bias Exploitation: Feeding someone only information that aligns with their existing beliefs to reinforce loyalty or prevent critical thinking.
18. Illusion of Choice: Offering multiple options that all lead to the same outcome or serve the manipulator’s interest.
19. Neuro-Linguistic Programming (NLP): (Controversial) A set of communication techniques claiming to influence behavior through language patterns—lacks strong empirical support but is widely used in persuasion contexts.
20. Artificial Urgency: Fabricating time pressure (“Offer ends in 10 minutes!”) to bypass rational deliberation.
21. Frequency Illusion (Baader-Meinhof Phenomenon): After noticing something new, it seems to appear everywhere—can be exploited via repeated exposure to normalize ideas.
22. Subliminal Messaging: Presenting stimuli below conscious awareness to influence attitudes or behavior (effectiveness is debated and often overstated).
23. Foot-in-the-Door: Starting with a small, easy request to increase compliance with a larger request later.
24. Strategic Incompetence (“Playing Dumb”): Pretending ignorance to avoid tasks, extract help, or lower others’ guard.

36. Authority Bias Exploitation: Using titles, uniforms, or credentials to gain unwarranted trust or obedience.
37. Mind Control: (Colloquial term) Refers to extreme, sustained manipulation that overrides autonomous thought—more accurately described as coercive persuasion.
38. False Identity Imposition: Assigning or reinforcing a role/identity (e.g., “You’re the responsible one”) to constrain behavior.
39. Social Proof Exploitation: Highlighting others’ behavior (“9 out of 10 people chose this”) to trigger conformity.
40. Reciprocity Principle: Giving a small gift or favor to create a sense of obligation to return the favor.
41. Stockholm Syndrome: A trauma response where hostages or victims develop empathy or loyalty toward their captors.
42. Learned Helplessness: Repeated exposure to uncontrollable negative events leads to passive acceptance—even when escape is possible.

Cognitive Biases

Cognition & Judgment

• Curse of knowledge: You forget what it was like to not know something—and therefore overestimate how much others understand.
• Blind Spot Bias: You believe that you are less affected by bias than others (meta-irony in the form of bias).
• Information Bias: You want more information, even if it is irrelevant to your decision.
• Ambiguity Effect: You avoid options whose probabilities are unclear.
• Belief Bias: You evaluate an argument based on whether you believe the conclusion – not on logic.
• Base rate fallacy: You ignore the base probability in favor of conspicuous (but rare) characteristics.
• Zero-risk bias: You prefer to eliminate a small risk entirely rather than greatly reduce a large one.
• Disposition Effect: In the financial world, you prefer to sell profitable investments rather than loss-making ones, even though this is irrational.
• Hard-Easy Effect: You underestimate difficult tasks and overestimate easy ones.
• Motivated Reasoning: Interpreting evidence to fit desired conclusions.
• Narrative Fallacy: Preferring coherent stories over complex or random truths.

Illusions & Perceptual Errors

• Illusory Superiority (Above-Average Effect): You consider yourself above average in many things – mathematically impossible.
• Illusory Correlation: You perceive connections where there are none (e.g., stereotypical connections).
• Illusion of Validity: You are convinced that your predictions are accurate – even if they are based on weak data.
• Placebo Effect: You feel an effect simply because you expect it.
• Nocebo Effect: The opposite of the placebo effect – you experience negative effects simply because you expect them.
• Mere Exposure Effect: Repeated stimuli seem more familiar and therefore more positive.
• Recency Illusion: You think a phenomenon is new just because you have only just discovered it.
• Hot-Hand Fallacy: You believe that a player is on a “winning streak” – even though the statistics say otherwise.
• Clustering Illusion: You see patterns in random events even though none exist.

Social Effects & Biases

• Pygmalion Effect: Higher expectations lead to better performance (also known as a self-fulfilling prophecy).
• Golem Effect: Low expectations lead to poorer performance.
• False uniqueness effect: You underestimate how many people have the same positive qualities as you.
• Projection bias: You assume that others think, feel, or act like you.
• Social desirability bias: You give answers that seem socially acceptable – even if they are not true.

• Pseudocertainty Effect: You prefer options that seem certain, even if the alternatives are rationally better.
• Ingroup/Outgroup Biases You favor people from your group/You see members of other groups as “all the same.”

Economic & Consumer Biases

• IKEA effect: You value things that you have (partly) built yourself more highly.
• Money illusion: You value money nominally, not in real terms (e.g., “higher salary” despite higher inflation).
• Projection Bias (Market Behavior): You believe that your current needs will remain the same in the future (e.g., buying a full refrigerator when you are hungry).
• Unit Bias: You consider a portion to be “normal” simply because that is how it is served—regardless of calories, etc.
• Default bias: You stick with default settings (e.g., data protection in apps) because it requires the least effort.
• Time-saving bias: You overestimate how much time you save by increasing your speed (e.g., driving 30 km/h faster makes little difference over a short distance).
• Choice-Supportive Bias: Remembering chosen options as better than they were.

Science & Statistics

• Publication Bias: Studies with positive results are published more often than those with negative results.
• Survivorship Bias: You only analyze the “survivors” and ignore those who did not make it (e.g., successful startups).
• Sampling Bias: The selection of your sample distorts the results (e.g., only surveying Twitter users).
• Observer Expectancy Effect: Your expectations as a researcher unconsciously influence the results.
• Reactivity (Hawthorne Effect): People change their behavior when they know they are being observed.
• File Drawer Problem (related to publication bias): describes the bias in scientific literature, as studies with non-significant or negative results are published less frequently, thereby creating an exaggeratedly positive picture of an effect.
• Reproducibility bias: Studies that are difficult to replicate are often overlooked—even though they would be important.

Attention & Perception

• Spotlight Effect: You think others pay much more attention to you than they actually do.
• Illusion of Transparency: You believe that your thoughts or feelings are easily recognizable to others.
• Change Blindness: You overlook obvious changes when your attention is elsewhere.

• Negativity bias: Negative information influences you more than positive information.

Memory Biases

• Hindsight Bias (“I knew it all along”): In retrospect, everything seems much more predictable than it really was.
• Mandela Effect: Many people collectively remember something incorrectly (e.g., “Berenstain Bears” vs. “Berenstein”).
• Peak-End Rule: You evaluate experiences based on the most emotionally intense moment and the end – not on the average.
• Misattribution of Memory: You remember something, but confuse the source or mix up details.
• False Memory: You remember things that never happened.
• Recency Effect: You remember the last piece of information in a series better.
• Primacy Effect: You remember the first piece of information better.

Decision-Making Biases

• Confirmation Bias: You specifically look for information that confirms your opinion.
• Anchoring Bias: Initial information has a disproportionate influence on your judgment.
• Availability Heuristic: You assess probabilities based on how easily you can think of examples.
• Representativeness Heuristic: You consider something more likely because it fits a stereotype.
• Gambler's Fallacy: You believe that random events have a “memory” (e.g., “A 6 has to come up soon”).
• Sunk Cost Fallacy: You keep going because you have already invested a lot—even though it would be more rational to stop.
• Framing Effect: How something is presented influences your decision (e.g., 90% chance of survival vs. 10% risk of death).
• Loss Aversion: Losses weigh more heavily psychologically than gains of equal magnitude.
• Affect Heuristic: Your spontaneous feelings (sympathy, fear, disgust, etc.) influence decisions more than objective facts or probabilities.

Self & Identity

Group & Social Dynamics

• False Consensus Effect: You believe that your opinions are more widespread than they actually are.
• Ingroup Bias: You favor people from your group (e.g., nationality, soccer team).
• Outgroup Homogeneity Bias: You see members of other groups as “all the same.”

• Moral Licensing: After doing a “good deed,” you feel freer to do something morally questionable.
• Present Bias: Overvaluing immediate rewards over future benefits.

Standalone Important Biases

• Conjunction Fallacy: You consider a specific combination (e.g., “bank employee and feminist”) to be more likely than the more general option (“just a bank employee”) – even though this is mathematically impossible.
• Regression to the Mean: Extreme values (e.g., very poor or very good performance) tend to regress toward the mean statistically when repeated – but we often interpret this as a real trend or effect.
• Reactance: hen people feel their freedom is threatened, they may do the opposite of what’s requested—manipulators may pretend to restrict choice to trigger this and push someone toward the desired action.
