8.2 Conformity, Obedience & Social Influence
Key Takeaways
- Conformity involves modifying behavior or beliefs to align with group norms, driven by either Informational Social Influence (desire to be correct, leading to internalization) or Normative Social Influence (desire to fit in, leading to public compliance).
- Solomon Asch demonstrated that individuals conform to an obviously incorrect unanimous majority roughly 37% of the time, but introducing a single dissenter reduces conformity by up to 80%.
- Stanley Milgram showed that 65% of participants would deliver maximum, lethal-labeled shocks (450V) under orders from an authority figure, shifting responsibility via an agentic state.
- Deindividuation occurs when high anonymity, large group size, and diffused responsibility reduce individual self-awareness, leading to uninhibited, anti-normative behavior.
- Compliance techniques exploit consistency and reciprocity: Foot-in-the-Door starts small to gain a large commitment, whereas Door-in-the-Face starts with an extreme request to extract a moderate concession.
8.2 Conformity, Obedience & Social Influence
Human beings are intensely social organisms whose behaviors, choices, and beliefs are continuously shaped by group membership and authority structures. For the MCAT, mastering social influence requires distinguishing between subtle group pressure (conformity), explicit direct requests (compliance), and orders from perceived authority figures (obedience).
The Spectrum of Social Influence
Social influence spans a spectrum based on the degree of direct pressure exerted and the structural power of the source:
[ Low Direct Pressure ] ----------------------------------------------> [ High Direct Authority ]
CONFORMITY COMPLIANCE OBEDIENCE
Matching group norms Yielding to direct requests Submitting to direct orders
(Peer pressure, social rules) (Sales techniques, favors) (Authority figures, superiors)
- Conformity: Adjusting one's behavior, attitudes, or beliefs to align with explicit or implicit group standards or norms without a direct order.
- Compliance: Changing behavior in response to a direct request from a person or group who lacks formal authority to enforce compliance.
- Obedience: Changing behavior in response to a direct command from an recognized authority figure who possesses institutional or structural power.
Conformity & Solomon Asch’s Line Judgment Experiments
In 1951, Solomon Asch designed a classic experiment to test whether individuals would conform to a group consensus even when the group was blatantly wrong.
Methodology
Naïve participants were placed in a room with 6 to 8 confederates (actors instructed to give predetermined wrong answers). Participants were shown a standard reference line alongside three comparison lines of differing lengths and asked to state aloud which line matched the standard line.
Findings
- Baseline Control: Working alone, participants made errors less than 1% of the time.
- Conformity Rate: When confederates unanimously gave an blatantly wrong answer, naïve participants conformed to the wrong majority 37% of the time across all trials.
- Participant Spread: Over 75% of participants conformed at least once during the experiment.
Boundary Variables in Conformity
- Group Size: Conformity increases sharply as group size grows from 1 to 3 confederates, leveling off after 4 to 5 confederates. Adding more confederates past 5 yields negligible increases in conformity.
- Unanimity: Group unanimity is paramount. When Asch introduced a single dissenting confederate who gave the correct answer (or even a different incorrect answer), participant conformity dropped dramatically by up to 80%.
- Public vs. Private Responses: When participants wrote their answers privately on paper rather than stating them aloud, conformity dropped significantly.
Types of Social Influence: Informational vs. Normative
Social psychologists distinguish two primary drivers of conformity, which yield different internal psychological outcomes:
| Feature | Informational Social Influence | Normative Social Influence |
|---|---|---|
| Primary Motivation | Desire to be accurate / correct | Desire to be accepted / avoid rejection |
| Trigger Condition | Ambiguous, complex, or unfamiliar situations | Clear situations with strong group social norms |
| Cognitive Process | Relies on others as a source of reality data | Relies on others for social approval |
| Behavioral Outcome | Internalization (True private acceptance) | Compliance (Public agreement, private doubt) |
| Clinical Example | Medical student adopting a diagnostic habit from an expert attending physician. | Resident agreeing with a chief's opinion during rounds despite private doubt. |
Three Levels of Social Conformity (Kelman)
- Compliance: Outwardly conforming to group expectations while maintaining private disagreement. Driven by fear of social sanction or desire for reward.
- Identification: Adopting behaviors or attitudes because of a desire to be like a specific valued individual or group (e.g., adopting a senior physician's bedside manner).
- Internalization: Integrating the group's values or beliefs into one's personal identity and cognitive framework. This represents the deepest, most permanent form of social influence.
Obedience & Stanley Milgram’s Shock Experiments
Conducted at Yale University in 1963, Stanley Milgram investigated the willingness of ordinary citizens to obey an authority figure instructing them to perform actions conflicting with their personal conscience.
Methodology
Participants were assigned the role of "Teacher" and instructed by an experimenter in a grey lab coat to administer electric shocks to a "Learner" (a confederate strapped to a chair in an adjacent room) for every incorrect answer on a word-pair memory task. Shocks scaled from 15 volts up to 450 volts (labeled "Danger: Severe Shock" and "XXX"). As shock levels rose, the learner pounded on the wall, screamed in agony, complained of a heart condition, and eventually went completely silent.
[ Experimenter (Authority) ] ----(Directives)----> [ Participant (Teacher) ] ----(Shocks)----> [ Confederate (Learner) ]
|
Agentic State Shift
("I am executing orders; he is responsible")
Key Results & Variations
- Baseline Finding: 65% (26 out of 40) of participants administered the maximum 450-volt shock, despite experiencing extreme physiological distress (sweating, trembling, stuttering).
- Proximity of Authority: When the experimenter gave orders via telephone instead of standing in the room, obedience dropped to 20.5%.
- Proximity of Victim: When the learner was in the same room as the teacher, obedience dropped to 40%. When the teacher was forced to physically push the learner's hand onto a shock plate (touch proximity), obedience fell to 30%.
- Institutional Prestige: Moving the study from Yale University to an unmarked, dilapidated office building in Bridgeport, CT reduced obedience to 48%.
- Peer Rebellion: When two confederate co-teachers refused to continue, participant obedience dropped to 10%.
Theoretical Mechanisms: Agentic State Theory
Milgram proposed that individuals move between two psychological mindsets in social hierarchies:
- Autonomous State: Individuals perceive themselves as independent agents acting on their own moral values and feeling personally responsible for their actions.
- Agentic State: Individuals perceive themselves as instruments executing the orders of an legitimate authority figure. Responsibility is psychologically transferred up the hierarchy to the commander ("I was just following orders").
Deindividuation & The Stanford Prison Experiment
Deindividuation refers to the loss of self-awareness, individual identity, and personal restraint that occurs when people are immersed in a group setting. It leads to uninhibited, often anti-normative or aggressive behaviors.
Key Antecedents of Deindividuation
- High Anonymity: Disguises, uniforms, masks, or dark environments reduce perceived personal accountability.
- Large Group Size: Diffuses personal responsibility across many individuals.
- Heightened Arousal: Loud music, shouting, or high-stress environments divert focus away from internal moral standards.
The Stanford Prison Experiment (Zimbardo, 1971)
Philip Zimbardo randomly assigned 24 healthy male college students to be either "guards" or "prisoners" in a simulated prison in the Stanford psychology basement:
- Deindividuation Triggers: Guards wore identical khaki uniforms, reflective sunglasses, and carried nightsticks. Prisoners wore numbered smocks and ankle chains.
- Outcome: Guards rapidly internalized their roles, becoming sadistic, abusive, and tyrannical. Prisoners exhibited severe helplessness, anxiety, and depression. The study was halted after just 6 days (planned for 14 days).
- Conclusion: Situational social roles and structural deindividuation can overpower individual moral codes, causing good individuals to commit harmful acts (The Lucifer Effect).
Strategic Compliance Techniques
Compliance techniques rely on fundamental social psychology principles such as self-consistency, reciprocity, and perceptual contrast:
| Technique | Mechanism | Sequential Steps | Underlying Psychological Principle |
|---|---|---|---|
| Foot-in-the-Door | Small initial request followed by larger target request. | 1. Ask for 5-minute survey.<br/>2. Ask for 2-hour volunteer commitment. | Self-Consistency: "I am a helpful person who supports this cause." |
| Door-in-the-Face | Extreme initial request (rejected) followed by smaller target request. | 1. Ask for $1,000 donation (Refused).<br/>2. Ask for $10 donation (Accepted). | Reciprocity / Perceptual Contrast: Target views concession as a favor to return. |
| Low-Ball | Secure agreement at low cost, then reveal hidden additional costs. | 1. Agree to buy car for $20,000.<br/>2. Add $2,000 in mandatory dealer fees. | Commitment / Cognitive Dissonance: Backing out after deciding creates tension. |
| That’s-Not-All | Present an initial offer, then immediately add bonus incentives before decision. | 1. Offer product for $50.<br/>2. Immediately include free shipping & extra accessory. | Norm of Reciprocity: Feeling like receiving a special personal deal. |
