Answer Key
1. B — Zajonc's drive theory: others' presence increases arousal, which facilitates well-learned, dominant responses and impairs complex, novel behaviors. This explains the contradictory early social facilitation findings — better performance on easy tasks, worse on difficult ones.
2. B — Social loafing decreases when individual contributions are identifiable. When accountability is clear, diffusion of responsibility cannot operate. Other conditions that help: task meaningfulness, group cohesion, small size.
3. C — Ringelmann found that individual rope-pulling effort decreased as group size grew. With 2 people, each pulled 93% of individual maximum; with 8, each pulled 49%. The pattern holds across many collective tasks.
4. B — Deindividuation conditions: anonymity (reduced identification), reduced self-awareness (attention externalized), group immersion (identity absorbed into group), and arousal (impairs deliberate processing). All four together produce the strongest deindividuation effects.
5. B — Mindguards are self-appointed group members who protect the group from information that might challenge the preferred direction. They filter out disconfirming evidence and discourage members from seeking outside consultation.
6. B — The out-group homogeneity effect (from Social Identity Theory/Chapter 36) is not one of Janis's eight groupthink symptoms. Janis's eight: illusion of invulnerability, collective rationalization, belief in morality, stereotyped views of outgroups, pressure on dissenters, self-censorship, illusion of unanimity, self-appointed mindguards.
7. C — High group cohesion is actually a condition that UNDERMINES collective wisdom by producing social pressure toward consensus. Surowiecki's four conditions: diversity of opinion, independence, decentralization, aggregation. Cohesion is a characteristic of groupthink, not wisdom of crowds.
8. B — Pluralistic ignorance: in ambiguous situations, people look to others for cues; if everyone else appears calm (because they too are waiting for cues), each person concludes the situation is not serious, producing a collective failure to recognize an emergency. Diffusion of responsibility is the other mechanism (answer A), but operates through perceived personal obligation, not through information about emergency severity.
9. C — Direct, specific request to a named individual eliminates diffusion of responsibility by directing personal accountability. "You, in the blue jacket — please call 911" is much more effective than a general appeal to bystanders. Fewer witnesses (not more, answer A) also reduce the effect.
10. C — 65% of Milgram's participants administered the maximum 450-volt shock. This result shocked the research community; expert predictions had been under 1%. The finding has been partially replicated by Jerry Burger (2009), who found 70% compliance to 150 volts (the point where the learner demanded to be released).
11. B — The agentic state: entering a hierarchical authority relationship shifts people from autonomous agency (acting on their own values) to agency in service of the authority (executing the authority's agenda). In the agentic state, people feel responsible to the authority for compliance, not to themselves for the moral quality of actions.
12. B — Telephone authority produced very low compliance (approximately 20%) — far lower than face-to-face authority. Physical presence of the authority is essential to maintaining authority's power. When the experimenter left the room, compliance dropped dramatically.
13. B — Two confederate teachers who refused to continue produced a drop from 65% to about 10% compliance. Breaking the unanimity of the group — providing social support for dissent — was the most powerful single manipulation. Consistent with Moscovici's minority influence research.
14. B — Emergent Norm Theory argues that crowd behavior is governed by situationally emerging norms, not by collective irrationality (Le Bon) or collective mind. This explains why most crowd behavior is orderly and normatively constrained, even in emergency situations.
15. C — Le Bon's core argument: crowds produce a collective mind through submergence of individual identity; crowds are irrational, emotional, suggestible, and impulsive. This was enormously influential despite having no systematic empirical foundation and reflecting clear class-based anxieties about mass political movements.
16. B — Collective action research: participation is driven by collective identity (sense of shared group membership), perceived injustice (belief that the group is being wrongly treated), and collective efficacy (belief that collective action can produce change). When all three are present, mobilization is most likely.
17. B — Psychological safety (Edmondson): the belief that one can speak up, disagree, ask questions, and make mistakes without being punished or humiliated. The key is interpersonal safety for risk-taking, not physical or competitive safety.
18. C — Project Aristotle's finding: of the five team dynamics they studied, psychological safety was by far the most important predictor of team performance. This surprised the Google researchers, who had expected to find that individual skill or team composition explained most of the variance.
19. C — The Stanford Prison Experiment primarily demonstrated situational role power: ordinary people who were randomly assigned to roles rapidly adopted those roles' behavioral patterns. The guard role produced authoritarian and cruel behavior in participants who showed no such tendencies before the study.
20. B — Small teams have lower process losses (coordination costs, social loafing, status effects on participation) and higher individual accountability. The research supports groups of 5–7 for most decision-making tasks; the "two-pizza rule" approximates this range.
21. B — The Kitty Genovese case (however distorted in its original media coverage) prompted Darley and Latané to study why witnesses fail to help, leading to the bystander effect and diffusion of responsibility research. The case became the catalyst for a paradigm shift in understanding prosocial behavior.
22. C — Zajonc's prediction: social facilitation improves well-practiced, dominant responses. An experienced musician performing a well-rehearsed piece benefits from the arousal of an audience. Novice performers (answer A), learners (answer B), and writers producing first drafts (answer D) are all in contexts where complex, non-dominant behavior is required — predicting inhibition rather than facilitation.
23. C — The agentic shift is possible because hierarchical relationships have legitimate social meaning: we accept that in institutional contexts, authority figures bear responsibility for outcomes. This legitimacy allows people to attribute moral responsibility upward — "I was following orders" — in a way that is sincere, not merely post-hoc rationalization. Gradual escalation (answer B) also contributes but is distinct from what makes the shift psychologically possible.
24. B — The situationist reading is important but incomplete: not everyone complied. About 35% refused at some point before the maximum, and the timing and form of refusal varied. Dispositional factors — moral courage, discomfort with authority, prior attitudes toward harm — predicted variation within the situational constraints. Situation and disposition both matter.
25. C — Research supports designating a devil's advocate and having the leader withhold initial preferences until the group has formed independent views. This addresses two core groupthink mechanisms: conformity pressure from the leader (reduced by withholding preferences) and the suppression of dissent (reduced by legitimizing and formalizing the dissent role). Anonymous voting (D) helps but is less consistently effective.
