Difficulty: Intermediate | Prerequisites: Chapters 1, 3 and 5 (especially norms)
This chapter asks one of social psychology's central questions: why do people go along with the group, even when the group is wrong or the instructions are harmful? It covers the three classic conformity and obedience paradigms (Sherif, Asch, Milgram), then examines the situational factors that increase or decrease obedience. You should be comfortable with norms (Chapter 5) and the fundamental attribution error (Chapter 3) before reading this material, because the chapter's punchline is that situations are more powerful than most people expect.
Conformity comes in three flavours: acceptance (you believe the group is right), compliance (you go along publicly but disagree privately) and obedience (you follow a direct order). Sherif showed norms emerge from group interaction, Asch showed people conform even on obvious perceptual tasks, and Milgram showed most people will obey an authority figure to an alarming degree. The key factors that increase obedience are emotional distance from the victim, closeness of the authority, institutional legitimacy and the absence of dissenting peers.
Conformity
A change in behaviour or belief as the result of real or imagined group pressure. In simple terms, adjusting what you do or think because of what others are doing or thinking.
Acceptance (true conformity)
Conformity that involves both acting and believing in accord with social pressure. Think of it as: you change your behaviour and you genuinely change your mind.
Compliance
Publicly acting in accord with a social request or norm while privately disagreeing. In simple terms, you go along with the group on the outside, but you still disagree on the inside.
Obedience
Acting in accord with a direct order or command from an authority figure. Think of it as: doing what you are told because someone with authority told you to.
Autokinetic effect
The perceptual illusion that a stationary point of light in a dark room is moving. Sherif used this to study how norms form.
Chameleon effect
The unconscious tendency to mimic the postures, gestures and expressions of those around us. In simple terms, you automatically copy the body language of the person you are talking to.
Mass hysteria (mass psychogenic illness)
Suggestibility to problems that spreads throughout a large group of people, sometimes including physical symptoms with no organic cause. Think of it as: a "contagious" belief that something is wrong, spreading faster than any real illness could.
Depersonalisation (in the context of obedience)
The emotional distancing of a victim, which makes it easier to harm them. In simple terms, the less human the victim seems, the easier it is to follow orders to hurt them.
Acceptance: you change both your behaviour and your private belief. You are persuaded.
Compliance: you change your behaviour publicly but keep your private disagreement. You are going along to get along.
Obedience: you follow a direct order from an authority figure.
Sherif used the autokinetic effect (a stationary light that appears to move in a dark room) to show that when people are uncertain, they converge on a shared group estimate.
This demonstrated that norms can emerge spontaneously from group interaction.
Everyday examples of our suggestibility: contagious yawning, laugh tracks on comedy shows, mood linkage in social groups, the chameleon effect (unconscious mimicry).
Mass hysteria is an extreme form: symptoms or fears spread through a group without an organic cause. Disturbing examples include socially contagious conversion disorder, suicide clusters and copycat violence.
Asch had confederates give obviously wrong answers on a simple line-comparison task, then observed whether the real participant would conform.
75% of participants conformed at least once. Overall, 37% of responses were conforming (i.e. wrong).
Some participants never conformed, but the majority did at least once, even though the correct answer was unambiguous.
Milgram's setup: a participant (the "teacher") was instructed by an experimenter to deliver increasingly severe electric shocks to a "learner" (a confederate) whenever the learner gave a wrong answer.
65% of participants continued to the highest voltage (450V), despite the learner's protests.
Results held even when the learner's protests were made more compelling and when later studies included women.
Four features of the study that mirror real-world compliance:
Slippery slope: small requests escalated gradually.
Framing: the task was presented as legitimate and normal.
Diffusion of responsibility: participants could tell themselves the experimenter was responsible.
Limited reflection time: the pace of the experiment left little room to stop and think.
Emotional distance from the victim (depersonalisation). The further removed the victim, the easier it is to obey.
Closeness and legitimacy of the authority. A nearby authority in a lab coat commands more obedience than a distant or informal one.
Institutional authority. The prestige of the institution (e.g. a university) lends weight to the orders.
Absence of dissenting peers (liberating effects of group influence). When another person in the room refused to obey, the participant was far more likely to refuse as well.
Milgram's findings help explain how ordinary people participate in atrocities: the situational pressures (authority, gradual escalation, diffusion of responsibility) are more powerful than most people expect. Understanding this is relevant to military obedience, corporate misconduct and any setting where authority can be misused.
Students often think Milgram's participants were sadistic or unusual. They were ordinary people. The point of the study is that the situation, not the person, drove the behaviour.
Students confuse compliance and acceptance. Compliance is public agreement without private belief change. Acceptance is both. If an exam question asks "which type of conformity is occurring," check whether the person's private belief has shifted.
Students sometimes think conformity is always bad. It is a normal and often useful social process. Norms keep traffic flowing and conversations orderly. The problem arises when conformity leads to harmful outcomes.
Students may believe that Asch's participants simply could not tell which line was correct. They could. The task was designed to be unambiguous. The conformity was social, not perceptual.
⚠️ Know all three types of conformity (acceptance, compliance, obedience) and be able to classify a given scenario into the correct type.
⚠️ The three classic studies (Sherif, Asch, Milgram) are almost certain to appear on an exam. For each, know the method, the key finding (including the specific percentages: 75% conformed at least once in Asch; 65% went to maximum voltage in Milgram) and what the study demonstrates.
⚠️ The four factors that breed obedience (emotional distance, authority closeness, institutional authority, group influence) are favourite short-answer material.
⚠️ Expect a question connecting Milgram to real-world atrocities or corporate misconduct. The answer should emphasise situational factors, not personality.
Fill in the blank: Publicly going along with a group while privately disagreeing is called ________. (Compliance.)
True or false: In Asch's line study, the correct answer was ambiguous. (False, the correct answer was obvious.)
Fill in the blank: In Milgram's study, ________% of participants delivered the maximum shock. (65%.)
True or false: Having a dissenting peer in the room made participants in Milgram-style studies more likely to obey. (False, a dissenting peer reduced obedience.)
Fill in the blank: Sherif demonstrated how ________ emerge from group interaction using the autokinetic effect. (Norms.)
Q: Define the three types of conformity and give an example of each.
A: Acceptance: a new employee adopts the company's values after working there for a year and genuinely believes in them. Compliance: a teenager dresses in a style they dislike because their friends all dress that way. Obedience: a soldier follows an order from a commanding officer.
Q: Describe Asch's line study. What was the key finding, and what does it tell us about social pressure?
A: Asch had confederates give obviously wrong answers on a line-comparison task. 75% of real participants conformed at least once, and 37% of all responses were conforming. This shows that people will agree with a unanimous group even when the correct answer is clear, highlighting the power of social pressure on behaviour.
Q: In Milgram's study, what percentage of participants obeyed to the maximum voltage, and what four situational features help explain why?
A: 65% obeyed to the maximum. The four features are: the slippery slope of escalating small requests, the framing of the task as a legitimate social norm, the opportunity to deny responsibility ("the experimenter told me to"), and limited time to reflect on the decision.
Q: Name the four factors that increase obedience and explain how each one works.
A: (1) Emotional distance from the victim: the less real the victim seems, the easier it is to obey. (2) Closeness of the authority: a nearby, visible authority commands more obedience. (3) Institutional authority: a prestigious institution lends legitimacy to the orders. (4) Absence of dissenting peers: when others refuse, the participant feels freer to refuse as well.
Q: A friend says, "Milgram's participants must have been unusually cruel people." How would you respond using what you have learned?
A: Milgram's participants were ordinary people, screened for psychological health. The lesson is that situational factors (gradual escalation, authority, diffusion of responsibility) are far more powerful than personality in driving obedience. Attributing the behaviour to the participants' character is itself an example of the fundamental attribution error.
Conformity connects directly to norms (Chapter 5) and to the fundamental attribution error (Chapter 3): people underestimate how much situations drive conformity and overattribute it to the person's character. Sherif's norm-formation work is a bridge between culture (Chapter 5) and group dynamics (later chapters). Milgram's findings connect to later discussions of aggression and prejudice, where obedience to authority and dehumanisation play central roles.
