12.4 Conformity, Compliance, and Obedience

Social Influence and Behavior

Social influence is a powerful force that shapes how you act, think, and feel. From conforming to group norms to obeying authority figures, your behavior is heavily influenced by the people around you, often without you even realizing it. The classic experiments by Asch and Milgram revealed just how strong this influence can be.

Conformity, Compliance, and Obedience

These three concepts describe different ways other people influence your behavior. They differ in how much pressure is involved and where it comes from.

Conformity means changing your behavior or beliefs to match those of a group. You conform because you want to be accepted (normative influence) or because you genuinely believe the group might be right (informational influence). This can happen even when nobody directly asks you to change.

Compliance is agreeing to a specific request from another person. Two classic techniques for gaining compliance:

• Foot-in-the-door: Someone starts with a small, easy request. Once you say yes, they follow up with a bigger one. You're more likely to agree to the bigger request because you've already committed.
• Door-in-the-face: Someone starts with a huge, unreasonable request that you'll almost certainly refuse. Then they follow up with a smaller, more reasonable one. The second request feels like a compromise, so you're more likely to say yes.

Obedience is following a direct order from an authority figure. Unlike conformity or compliance, obedience involves a clear power dynamic where someone with perceived authority tells you what to do.

Social norms are the unwritten rules that guide behavior in specific situations. Descriptive norms describe what people typically do (e.g., most students are quiet in the library). Injunctive norms describe what people should do (e.g., you should hold the door for someone behind you). People often conform to these norms to avoid disapproval or gain acceptance.

Asch's Conformity Experiments

Solomon Asch studied conformity in the 1950s with a simple but clever setup. Participants were placed in a group and asked to judge which of three comparison lines matched a standard line. The correct answer was obvious.

Here's the catch: everyone else in the group was a confederate (someone secretly working with the experimenter). On certain trials, all the confederates deliberately gave the same wrong answer before the real participant responded.

Key findings:

• 75% of participants conformed to the group's clearly incorrect answer at least once across the trials
• On average, participants conformed about one-third of the time
• Many participants later said they knew the group was wrong but went along to avoid standing out

Conformity decreased when:

• At least one other person in the group gave the correct answer (having even one ally made a big difference)
• Participants wrote their answers privately instead of stating them aloud
• Participants were not face-to-face with the group

Asch's experiments showed that social pressure can lead people to deny what their own eyes are telling them, even on a task with an objectively clear answer.

Milgram's Obedience Studies

Stanley Milgram conducted his famous obedience experiments in the 1960s, partly inspired by questions about how ordinary people carried out atrocities during the Holocaust.

The setup:

1. Participants were told the study was about the effects of punishment on learning.
2. The participant played the role of "teacher" and a confederate played the "learner."
3. The teacher was instructed by an experimenter (the authority figure) to administer electric shocks to the learner each time they answered a question incorrectly.
4. The shocks increased in 15-volt increments, from 15 volts up to 450 volts (labeled "XXX" on the machine).
5. The learner was never actually shocked, but the participant didn't know this. They heard pre-recorded cries of pain, protests, and eventually silence from the learner.

Key findings:

• 65% of participants administered the maximum 450-volt shock when instructed to do so
• Most participants showed visible distress (sweating, trembling, protesting) but continued anyway when the experimenter insisted

Factors that increased obedience:

• The experimenter's perceived legitimacy (a scientist in a lab coat at a prestigious university)
• Gradual escalation of the shocks, starting small and increasing bit by bit, so there was no obvious point to stop
• Physical distance from the learner (obedience dropped when the participant was in the same room or had to physically place the learner's hand on the shock plate)
• The participant's belief that the experiment served a worthy scientific purpose
• The presence of other obedient participants in some variations

Obedience decreased when:

• The experimenter was not physically present (e.g., gave instructions by phone)
• Other "teachers" in the room refused to continue
• The experiment was conducted in a less prestigious setting

Milgram's studies revealed that ordinary people can be led to cause serious harm when directed by an authority figure, especially when responsibility feels diffused and demands escalate gradually. These findings remain some of the most discussed and debated results in all of psychology.
