Influence: The Psychology of Persuasion

Cheatsheet Content

Weapons of Influence People often respond mindlessly to a single "trigger feature" in a situation, rather than analyzing all available information. This automatic, "click, whirr" response, while efficient, makes us vulnerable to those who know how to trigger these responses for their own benefit. Example: Turquoise jewelry selling out at twice its original price after a saleswoman mistakenly marked it as "price $\times 2$". Customers, lacking knowledge, used "expensive = good" as a shortcut. 1. Reciprocation: The Old Give and Take...and Take Rule: We should try to repay, in kind, what another person has provided us. Creates a sense of obligation for future repayment of favors, gifts, and invitations. Pervasiveness: Found in all human societies; a unique adaptive mechanism for human culture, allowing for labor division and exchange. Uninvited Debts: The rule creates a feeling of indebtedness even for unrequested favors. Example: A professor sending Christmas cards to strangers received many in return, illustrating automatic reciprocation. Overpowering: The rule can overpower other factors, like dislike for the requester. Regan Study: A confederate offering a small, unsolicited favor (a Coke) significantly increased the likelihood of subjects buying raffle tickets from him, regardless of whether they liked him. Hare Krishna Society: Giving a small "gift" (flower, book) before asking for donations significantly increased contributions, even from those who disliked the group. Reciprocal Concessions (Door-in-the-Face Technique): If someone makes a concession to us, we feel obligated to make a concession in return. Start with a large request likely to be rejected, then retreat to a smaller, desired request. The smaller request appears as a concession, increasing compliance. Example: Boy Scout first asking to buy expensive circus tickets, then retreating to cheaper chocolate bars. Effectiveness: This technique combines the reciprocity rule with the perceptual contrast principle (the smaller request seems even smaller after the larger one). Watergate Example: Liddy's initial extreme proposals made the $250,000$ break-in plan seem like a "concession" and therefore acceptable. Positive Side Effects: Increases feelings of responsibility and satisfaction with the final agreement, leading to higher follow-through rates. How to Say No: Recognize when a favor or concession is a compliance tactic, not a genuine gesture. Redefine the offer as a sales device rather than a gift to neutralize the obligation. Exploit the exploiter: Accept the "gift" but refuse the subsequent request if it's manipulative. 2. Commitment and Consistency: Hobgoblins of the Mind Principle: Once we make a choice or take a stand, we feel personal and interpersonal pressure to behave consistently with that commitment. Automatic Consistency: A shortcut that allows us to avoid hard thinking, especially in complex environments. It also serves as a "hiding place" from troubling realizations. Commitment is Key: Making a commitment (taking a stand, going on record) sets the stage for automatic consistency. Foot-in-the-Door Technique: Start with a small request to gain compliance, which then makes people more likely to agree to larger, related requests. Example: Homeowners who agreed to display a small "Be a Safe Driver" sign were much more likely to agree to display a large, unsightly "DRIVE CAREFULLY" billboard two weeks later. Changing self-image: The small commitment causes individuals to see themselves as "public-spirited," making them consistent with this new self-image. Effective Commitments: Most effective when they are: Active: Require direct action, not passive agreement. Public: Visible to others, increasing the drive to maintain the stand to appear consistent. Effortful: The more effort put into a commitment, the greater its ability to influence attitudes. Initiation Rites: Fraternities and tribes use severe, effortful initiation ceremonies (e.g., hazing) to increase commitment and loyalty to the group. The pain and effort make members value the group more. Inner Choice: People accept inner responsibility for behavior when they believe they chose to perform it in the absence of strong outside pressures. Small Rewards/Threats: Commitments are stronger if they are not induced by large rewards or strong threats, as these provide external justification, reducing inner responsibility. Child Rearing: To instill lasting belief in a behavior, use reasons just strong enough to produce compliance, allowing the child to take inner responsibility. Lowball Tactic: An item is offered at a very good price (inducement), then the decision is made, and the original purchase advantage is removed. The customer often still buys due to the commitment and newly generated justifications. Example: Car dealerships offer a low price, then later claim "errors" or "boss's refusal" to add costs back. Customers, having committed, often accept. Creates new, self-generated reasons to justify the decision, even if the original reason is removed. How to Say No: Listen to your "stomach signs" (gut feelings) when you feel trapped into complying with an unwanted request due to prior commitments. Ask yourself: "Knowing what I now know, would I make the same choice again?" Focus on the objective merits, not just consistency. Recognize and call out manipulative tactics that exploit consistency. 3. Social Proof: Truths Are Us Principle: We determine what is correct by finding out what other people think is correct. We view a behavior as more correct in a given situation to the degree that we see others performing it. Efficiency: Often a useful shortcut, as acting in accord with social evidence usually leads to fewer mistakes. Vulnerability: Makes us susceptible to manipulation when social proof is faked or misleading. Canned Laughter: TV executives use laugh tracks to make material seem funnier, exploiting our tendency to respond to social cues even if artificial. "Salted" Tip Jars: Bartenders and church ushers place money in collection containers to give the impression that tipping/donating is proper behavior. Advertisers: Use "fastest-growing" or "largest-selling" claims to imply product quality and popularity. Optimal Conditions for Social Proof: Uncertainty: When we are unsure, the situation is unclear, or ambiguity reigns, we are most likely to look to others for guidance. Bystander Effect (Pluralistic Ignorance): In an emergency, if multiple bystanders are present, each person is less likely to help because they look to others for cues. If no one reacts, everyone assumes it's not an emergency. Example: Catherine Genovese's murder, where 38 witnesses did not intervene because each assumed others would or had already acted. Victim Strategy: To get help in an emergency, isolate one individual, make eye contact, point, and clearly state "Help me, call an ambulance!" to assign responsibility and remove uncertainty. Jonestown Mass Suicide: The extreme uncertainty of the jungle environment and the lack of familiar social cues made cult members highly reliant on each other's actions, leading to mass compliance with the suicide command. Similarity: We are most influenced by the actions of people who are similar to us. Example: Children were more likely to overcome dog phobia by watching films of other children (especially those of similar age) interacting with dogs. Werther Effect (Copycat Suicides): Highly publicized suicides lead to an increase in suicides among similar individuals (e.g., young people copying young suicides). Homicides: Publicized acts of aggression can lead to copycat homicides among similar groups. How to Say No: Be alert to faked social proof (e.g., clearly staged testimonials, canned laughter). Consciously recognize and reject deliberately falsified evidence. When social proof is genuinely occurring but leading to a poor choice (e.g., "everyone else is doing it," but it's a mistake), pause and critically evaluate the situation against objective facts, previous experiences, and your own judgment. 4. Liking: The Friendly Thief Principle: We are more likely to comply with requests from people we know and like. Exploitation: Compliance professionals leverage this rule by making us like them. Tupperware Parties: Success comes from customers buying from friends (the hostess) rather than an unknown salesperson. The social bond is a stronger predictor of purchase than product preference. Endless Chain Method: Salespeople ask satisfied customers for names of friends who might also like the product, using the friend's name as an introduction to new prospects. Factors that Increase Liking: Physical Attractiveness: Good-looking people are more liked, persuasive, and receive more favorable treatment. This creates a "halo effect" where positive traits are automatically assigned. Examples: Attractive political candidates get more votes, attractive defendants receive lighter sentences, and attractive people are more likely to get help. Similarity: We like people who are similar to us in opinions, personality traits, background, or lifestyle. Examples: Salespeople mimic customer body language or background details (e.g., finding camping gear in trunk) to create rapport. Dress: People are more likely to help those dressed similarly to them. Compliments: We are phenomenal "suckers for flattery" and tend to believe praise, even if it's clearly false, and like those who provide it. Joe Girard: World's "greatest car salesman" sent "I like you" cards to customers monthly. Contact and Cooperation: Increased familiarity through repeated contact often leads to increased liking, especially when contact involves cooperation toward common goals. School Desegregation: Simple contact (busing) often increased prejudice when competitive environments fostered hostilities. However, cooperative learning (e.g., "jigsaw classroom") increased liking and reduced prejudice. Good Cop/Bad Cop: The "Good Cop" gains the suspect's liking by appearing to be on their side and cooperating, making them more likely to confess. Conditioning and Association: We tend to like people or things that are associated with positive things (even if the association is superficial) and dislike those associated with negative things. Example: Ancient Persian messengers bringing bad news were killed. Weathermen: Often blamed for bad weather, even though they only report it. Celebrity Endorsements: Products are linked to popular figures to transfer positive feelings. Luncheon Technique: People become fonder of people and things experienced while eating. How to Say No: Focus on the request itself, separating it from feelings about the requester. Be alert to a sense of "undue liking" for a compliance professional – if you like them more than expected under the circumstances, it's a signal to evaluate the offer critically. Mentally separate the requester from the merits of their offer. 5. Authority: Directed Deference Principle: We tend to obey authority figures, even if their commands conflict with our moral compass. Efficiency: Obedience to authority is often a sensible shortcut for making decisions, as authorities often possess greater knowledge and power. Vulnerability: We can be exploited when this automatic obedience is triggered by mere symbols of authority, rather than genuine authority. Milgram Experiment: Subjects were willing to deliver increasingly severe electric shocks to a "Learner" (confederate) when instructed by an "Experimenter" (authority figure in a lab coat), even when the Learner expressed extreme pain. Rectal Earache: A nurse administered ear drops rectally because the doctor's prescription said "place in R ear," illustrating mindless deference to authority. Symbols of Authority: These can trigger automatic compliance even in the absence of genuine authority. Titles: (e.g., Doctor, Professor, President). Example: A man introduced as a "professor" was perceived as taller than when introduced as a "student." Can make people seem more credible and knowledgeable. Clothes: Uniforms (e.g., security guard, police) and expensive business suits can convey authority and status. Example: People were more likely to comply with requests from someone dressed as a security guard. Jaywalking Experiment: People were more likely to follow a jaywalker dressed in a business suit. Trappings: Status symbols like expensive cars or jewelry. Example: Motorists honked less quickly at a luxury car blocking traffic than an economy car. How to Say No: Is this authority truly an expert? Focus on the authority's credentials and their relevance to the topic at hand. Don't be swayed by mere symbols. How truthful can we expect the expert to be? Consider whether the authority has a personal stake in your compliance. Be wary of those who argue against their own minor interests to appear trustworthy, especially if the gain from your compliance is significant. 6. Scarcity: The Rule of the Few Principle: Opportunities seem more valuable to us when their availability is limited. Efficiency: We use an item's availability as a shortcut for judging its quality; things that are difficult to possess are often better. Vulnerability: We are motivated by the thought of losing something more than by the thought of gaining something of equal value. Limited-Number Tactic: Customers are informed that a product is in short supply or won't last long, increasing its perceived value. Deadline Tactic: A time limit is placed on an opportunity, pressuring individuals to act quickly before it's gone. "Precious Mistake": Flawed or rare items (e.g., misprinted stamps) become highly valued due to their scarcity. Psychological Reactance: When our freedom to choose or access something is limited or threatened, we desire that item (and the freedom) significantly more than before. "Terrible Twos": Young children assert their independence by resisting restrictions and wanting what they can't have. "Romeo and Juliet Effect": Parental interference in a romantic relationship can intensify the couple's feelings and commitment due to the perceived threat to their freedom. Censorship: Banned information is desired more and viewed more favorably, even if not directly consumed. Commodity Theory: Information that is exclusive or scarce is perceived as more persuasive and valuable. Newly Experienced Scarcity: Items that have recently become less available are desired more than items that have always been scarce. Competition for Scarce Resources: The desire for an item intensifies when we are in competition with others for it. "Goosing 'em off the fence": Real estate agents create artificial competition (e.g., claiming other buyers are interested) to pressure indecisive clients. Auctions: The competitive environment of an auction drives up perceived value and bidding, often beyond rational limits. How to Say No: Recognize Arousal: When you feel the emotional arousal that comes from scarcity (e.g., panic, feverishness), use it as a signal to pause and calm down. This is not the time for rational decision-making. Evaluate Intrinsic Value: Ask yourself: "Why do I want this item?" Distinguish between the desire to possess something rare versus its utility value. The scarce cookies don't taste better. If the desire is purely for possession due to scarcity, reconsider if it's truly worth the inflated value.
