Chapter 12 — Social Influence: Conformity and Obedience (Notes on the Milgram and Asch paradigms)

Conformity

  • Definition and scope
    • Conformity is changing behavior to go along with a group; it is often described as the weakest form of social influence but is essential for social norms and stability.
    • Norms guide expected behavior; without conformity, social norms would erode and social order could falter.
    • Conformity can be positive (when the group’s norms are positive) or problematic (when the group engages in harmful or unethical behavior). People may go along with the group even if they aren’t fully on board.
    • People may conform for many reasons and not necessarily because they truly agree with the group; motivation can be mixed (some reasons are stronger than others).
  • Why people conform: two main mechanisms
    • Normative social influence: we conform to be liked and accepted by others; social belonging and fear of rejection motivate conformity.
    • Informational social influence: we conform because others have information we think we lack and we want to be right (seek correct behavior by using others as a source of information).
    • It’s important to note that informational influence does not always apply in Asch’s line-judgment context because the control condition (participants alone) shows correct answers most of the time, suggesting incorrect group answers were not due to participants’ ignorance but social pressure.
  • Solomon Asch conformity study (1951): design and setup (as described in the transcript)
    • Two conditions:
    • Alone condition: participants make line-judgment decisions by themselves.
    • Group condition: participants sat in a row with confederates; only the last seat is empty, so the participant sits at the end and answers after others.
    • Task: identify which of the comparison lines matches the standard line in length.
    • Example problem (typical): standard line on the left; comparison lines on the right; the obvious correct choice is the line labeled with the same length as the standard.
    • Procedure detail: in the group condition, the first several participants (confederates) give an incorrect answer; then the actual participant is asked to respond last.
    • Independent variable: group size (number of confederates giving responses before the target participant).
    • Key manipulation insight: after a few trials, the first person may give a wrong answer, followed by others; the real test is what the participant does when the group past the point of consensus gives a wrong answer.
  • Results and interpretation
    • Alone condition: mistakes were rare; people performed the task reliably when not under group pressure.
    • Group condition: conformity increased; about 0.37 of responses were incorrect (roughly 37%). In the transcript, this is presented as a clear contrast with the control condition.
    • Overall, about three out of four participants conformed to the group’s wrong answers at least once (i.e., the proportion who conformed at least once is rac{3}{4} = 0.75).
    • This demonstrates the power of social influence in situations where individuals are in a group with a wrong perceived consensus.
  • Why people conform in ASH-style experiments (and what the results imply)
    • Normative influence is a likely driver: participants desire acceptance and fear rejection from the group, leading to conformity even when one knows the correct answer.
    • The informational explanation (relying on others for the right answer) fails in this context because the control condition shows participants know the right answer when alone; thus, deviations in the group condition are not due to ignorance but social pressure.
    • People may experience a tension between wanting to be accepted and wanting to be correct; sometimes the need for acceptance overrides the drive to be right.
    • The social environment can create fatigue or pressure: after being in situations where conformity is expected, people may increasingly go along with the group as a form of effort to avoid standing out.
  • Key takeaways and implications
    • Conformity helps maintain social order and norms, especially when the group is cohesive, legitimate, or appears to have more information.
    • However, conformity can lead to erroneous or harmful outcomes when the group’s consensus is wrong or unethical.
    • The presence of a dissenting model or an ally can dramatically reduce conformity and increase independent judgment.
  • Examples and metaphors mentioned in the lecture
    • Forks at a fancy restaurant as an informational example: people look to others to decide which fork to use when a new or confusing situation arises.
    • The general idea: we use others as a cue for how to behave, especially in ambiguous situations.
  • Connections to foundational concepts
    • Norms and social scripts shape everyday behavior; conformity underpins social cohesion but can yield harm when norms are harmful.
    • Distinction between normative and informational influence helps explain why people conform in some scenarios but not others.
  • Practical and ethical implications
    • In workplaces, schools, and public life, conformity can influence decision-making and moral judgments.
    • Understanding conformity helps us design environments (e.g., fostering dissenting voices, critical thinking) that reduce harmful conformity.

Obedience

  • Definition and contrast with conformity
    • Obedience involves changing behavior in response to an explicit request or directive from an authority figure; the authority’s status or position prompts compliance, even if the command conflicts with personal morals.
    • Milgram’s obedience research is among the most famous demonstrations of how ordinary people can be driven to harm others under an authoritative command.
  • Milgram’s obedience experiments (1962): overview and rationale
    • Historical motivation: to understand how ordinary people could participate in atrocities in Nazi Germany; the question was whether obedience to authority is a universal tendency or context-dependent.
    • Setup (a series of experiments, with the classic laboratory design described in the transcript):
    • Recruitment: participants volunteered via newspaper advertisements for a study of memory; payment offered; the paper claimed the study examined learning and memory.
    • Roles: ordinary participant (teacher) and a learner (an accomplice); the learner is strapped in and separated by a wall so the teacher cannot see the learner’s reactions.
    • Task: the teacher reads word pairs to the learner and tests the learner on recall. The learner’s incorrect answers trigger electric shocks from an attached shock generator.
    • Shock levels: the shock increments from 15 ext{ V} to 450 ext{ V}, with labeled descriptors such as “a little bit of pain,” “strong shock,” “extreme intensity,” “severe danger,” and “XXX.”
    • The teacher believes the learner is receiving real shocks; the learner’s responses are scripted and no real shock is delivered.
    • The experimenter (an authority figure) is present in the room and issues standard prods to encourage continuation.
  • Nature of the prods and the authority dynamic
    • Prods used to pressure continued obedience (in increasing severity):
    • “Please continue.”
    • “The experiment requires that you continue.”
    • “It is essential that you continue.”
    • “You have no other choice; you must go on.”
    • The experimenter’s role is to present the authority, monitor behavior, and push the participant to obey despite distress.
  • Key results and what they suggest
    • In the basic, on-campus version, about two-thirds of participants delivered all 30 shocks to the maximum level (approximately rac{2}{3} ext{ of participants} or about 65%).
    • Variations show how the context shapes obedience:
    • Off-campus (New Haven Research Institute): obedience rate dropped to about 0.48 (roughly 48%), indicating reduced perceived legitimacy when the setting lacks the prestige of Yale.
    • Physical proximity of the experimenter: when the experimenter left the room or when the participant could communicate via telephone rather than directly in the room, obedience dropped further to about 0.20 (20%).
    • Proximity of the victim: the more physically close the learner/victim is, the harder it is to obey; obedience drops when the learner is not in a different room (closer distance) and is even lower when the learner and teacher are in the same room or when the victim’s hand is held on a shock plate.
    • Closer victim: holding the victim’s hand on a shock plate significantly reduces obedience; in some conditions, about one-third still delivered all shocks even with direct contact.
  • Responsibility and accountability
    • A critical factor: responsibility for the harm.
    • When the experimenter reassured the teacher that he was responsible for what happened, obedience dropped dramatically; when participants were told the experimenter was responsible, obedience effectively collapsed to zero.
    • The allocation of responsibility reduces the perceived personal accountability and increases obedience in high-pressure situations.
  • Role of models and social influence
    • Observing others who obey (obedient models) increases the likelihood of continued obedience; about 90% of participants obeyed when they witnessed another person obeying.
    • Observing others disobey (disobedient models) dramatically reduces obedience; when a peer disobeyed, only about 10% of participants delivered all 30 shocks.
    • The presence of a dissenting model provides social proof that resistance is possible and can empower others to resist authority.
  • Gradual escalation as a mechanism
    • The sequence of gradually escalating demands makes it psychologically easier to continue; each small step mirrors the previous one, so stopping becomes harder as the voltage increases.
    • If the escalation were stopped at a mid-point or if a break were allowed early, it’s likely that no one would resume; the incremental nature creates momentum toward the maximum shocks.
  • Robustness of the effect and important caveats
    • The core finding: under the right (or wrong) conditions, ordinary people can commit actions they would morally reject when guided by an authority.
    • The lecture emphasizes that the lesson is about the power of situational factors rather than about character flaws in participants.
  • Gender and victim considerations
    • Questions sometimes arise about whether obedience would differ if the teacher and/or victim gender changed; the general finding cited is that obedience rates do not depend on the gender of the teacher or the victim in the same way they might on other factors.
    • Variants explored (e.g., female teachers, male vs female victims, heart-condition disclosures, or puppy victims) generally do not overturn the central message that situational factors drive obedience rather than dispositional traits.
  • Ethical and philosophical implications
    • Milgram’s experiments sparked intense ethical debate about the treatment of subjects and the potential for psychological harm.
    • The takeaway is not that people are “bad,” but that under certain social and situational pressures, ordinary people can be led to commit acts they would ordinarily reject.
    • The findings underscore the importance of accountability, the presence of dissenting voices, and the need to design systems and organizations that resist harmful obedience (e.g., encouraging whistleblowing, reducing perceived legitimacy of coercive commands).
  • Real-world relevance and examples raised in the lecture
    • War contexts: the distinction between distant vs. close proximity to the victim and the authority in the chain of command affects obedience in ways that mirror Milgram’s variations.
    • Cults and group dynamics: gradual escalation can lead to extreme outcomes, such as collective acts or self-harm, by slowly increasing commitment and reducing perceived personal responsibility.
  • Summary of the overarching message
    • The primary insight is the power of the situation and social influence processes to shape behavior, including obedience to authority and conformity to group norms.
    • By understanding these dynamics, we can better recognize when we are at risk of conforming or obeying in harmful ways and design safeguards to promote ethical judgment and individual responsibility.

Key concepts, terms, and formulas (quick reference)

  • Conformity: changing behavior to align with group norms.
  • Normative social influence: conformity to be accepted or liked by others.
  • Informational social influence: conformity to be correct when others are perceived to have information.
  • Obedience: changing behavior in response to an explicit directive from an authority figure.
  • Milgram’s voltage scale: 15\text{ V}, 30\text{ V}, 45\text{ V}, \ldots, 450\text{ V}
  • Major Milgram findings: ext{On-campus obedience rate} \approx 0.65 (65%), ext{off-campus obedience rate} \approx 0.48; overall basic result: \approx \frac{2}{3} of participants delivered all 30 shocks.
  • Influence of proximity and responsibility:
    • Proximity of authority and victim, location, and assignment of responsibility drastically shape obedience.
    • When responsibility is assigned to the authority, obedience drops substantially.
  • Modeling effects:
    • Obedient models raise obedience rates; disobedient models reduce obedience rates (roughly 9/10 vs 1/10 in the described contexts).
  • Gradual escalation: small, incremental demands accumulate to sustain obedience; interruption breaks the momentum.
  • Real-world implications: social influence processes operate in everyday life, workplaces, military, and crisis situations; critical for understanding how to promote ethical choices under pressure.
