Course: Social Psychology (NYU) Source: Case study essay, "The Experiment" film analysis Difficulty: Intermediate Prerequisites: Group Theory and Group Dynamics study notes (Part 1 of this series). Familiarity with how groups form and develop norms is assumed here.
Leadership is not a fixed trait that some people have and others lack. In social psychology, leadership is studied as a dynamic process shaped by the situation, the group's needs, and the norms already in play. A person who leads constructively in one context can become destructive in another, and vice versa.
This topic builds directly on group dynamics. Once you understand how groups form, set norms, and enter conflict, the next question is: who steers the group through those stages, and what happens when that steering goes wrong? "The Experiment" provides a case study in which the same individuals shift between positive and negative leadership depending on role pressure, authority structures, and the behaviour of those around them.
Leadership in groups can be positive (oriented toward the wellbeing of all members) or negative (self-serving or coercive, with followers complying out of fear or pressure). Role assignment and situational pressures can transform a person's leadership style rapidly. In "The Experiment," a pacifist prisoner becomes a revolt leader, and a reluctant guard becomes an authoritarian, all driven by the dynamics of their assigned roles and the escalating environment.
Positive leader
A leader whose actions are directed toward the wellbeing of all group members, and who retains the group's voluntary support. Think of it as leading by looking after others: they follow because they trust you.
Negative leader
A leader whose actions serve their own interests or harm the group, but who is followed nonetheless, often because members fear consequences for dissent. In simple terms, people comply not out of trust but out of pressure.
Role pressure
The psychological force exerted on an individual to behave in ways consistent with their assigned or expected role, even when that behaviour conflicts with their personal values.
Situational leadership
The idea that leadership effectiveness depends on context. The same individual may lead well in one situation and poorly in another, depending on the group's needs, the task, and external pressures.
Authority structure
The formal or informal hierarchy that determines who has decision-making power within a group, and how that power is enforced.
Monetary stimulus
An external financial incentive used to motivate behaviour. In "The Experiment," the promise of payment was the primary reason participants accepted their roles, and the threat of losing it pressured them to maintain those roles.
The experiment's director (the "doctor") functions as a meta-leader: he designs the situation, assigns roles based on psychological profiles, and sets the rules that constrain all participants.
He deliberately places individuals into roles that conflict with their natural dispositions. For example, Participant 077, a pacifist by temperament, is assigned to the prisoner group. A participant who lived with his mother and had a history of being subject to authority is placed among the guards.
The director's choices illustrate a key concept: leaders shape outcomes not only through direct commands but through the structures and conditions they create.
077 begins the experiment as a positive leader among the prisoners. He looks out for the wellbeing of his peers, and they voluntarily support his decisions.
His leadership is characterised by care and solidarity, consistent with what the literature calls prosocial or transformational leadership in informal settings.
However, his positive leadership is not permanent. As the guards' behaviour escalates and a friend (now a guard) betrays their relationship by treating him as "just another prisoner," 077's leadership transforms.
Among the guards, a small faction (roughly three members) takes the lead in escalating punishment and psychological humiliation.
One guard proposes the principle of "respond proportionally," but in practice the dominant guards push well beyond proportionality, advocating that prisoners should be "humiliated until they broke."
The other guards follow this escalation even when they disagree, illustrating how negative leadership can persist when group members comply out of pressure or fear of exclusion rather than agreement.
A clear example: one guard wants to help a sick prisoner, but the dominant leader punishes the prisoner instead, and the others fall in line.
077's arc is the most significant leadership transformation in the film. He begins as a positive leader (prosocial, caring) but, under sustained abuse and betrayal, becomes a negative leader who organises a violent riot.
This shift illustrates that leadership style is not fixed. Situational factors (oppression, loss of trust, environmental stress) can convert a constructive leader into a destructive one.
The lesson for the exam: when you see a question about leadership change, look for the situational trigger. The person did not simply "reveal their true nature"; the context transformed their behaviour.
Before the experiment, participants who would become guards and prisoners got along as equals. Friendships formed across what would become group boundaries.
Once roles were assigned, those friendships collapsed under role pressure. The guard who was 077's friend began treating him as a subordinate because the experiment's authority structure (and the threat of losing payment) made the role feel more real than the friendship.
This connects to a broader principle in social psychology: assigned roles exert powerful behavioural pull, often overriding personal values and prior relationships. The uniform, even when "not real," changes behaviour.
The dynamics shown in the film map onto real organisational settings. A manager who leads positively under normal conditions may become coercive under extreme deadline pressure or threat of job loss. Military leadership research documents similar shifts: soldiers who are effective peacetime leaders sometimes behave very differently under combat stress. The takeaway is that organisations need to design structures and safeguards that support positive leadership even under pressure, because relying on individual character alone is not sufficient.
"Leaders are born, not made." Social psychology emphasises the situational nature of leadership. The same person can be a positive or negative leader depending on context. Dispositional traits matter, but they interact with situational forces.
"A negative leader must be a bad person." Not necessarily. Negative leadership often emerges from structural pressures (role demands, authority hierarchies, financial incentives) acting on otherwise ordinary people. This is one of the central lessons of prison experiment research.
"If followers disagree, they will resist." The film shows that disagreement alone is not enough. Guards who disagreed with the dominant faction still complied, at least initially. Resistance requires a tipping point, often when the cost of compliance exceeds the cost of dissent.
"Positive leaders cannot become negative leaders." 077's transformation proves otherwise. Sustained situational pressure can shift leadership style dramatically.
⚠️ Be prepared to distinguish positive from negative leadership with specific behavioural examples, not just definitions.
⚠️ Know how role pressure interacts with leadership. A common exam question: "Explain how an assigned role can alter leadership behaviour."
⚠️ The transition from positive to negative leadership (077's arc) is a high-probability essay or short-answer topic.
⚠️ Understand the experiment director as a structural leader. Questions may ask about indirect forms of leadership (designing the situation vs. giving direct orders).
True or False: Positive leadership is a permanent personality trait. (False: it can shift under situational pressure.)
Fill in the blank: The experiment director shaped outcomes primarily through ______, not direct commands. (Structural design / role assignment.)
True or False: The guards who disagreed with the dominant faction immediately resisted. (False: they initially complied before eventually withdrawing support.)
Fill in the blank: The external incentive that pressured participants to stay in their roles was the ______ ______. (Monetary stimulus / financial payment.)
Q: Describe the difference between positive and negative leadership as illustrated in "The Experiment." Give one example of each.
A: Positive leadership is demonstrated by Participant 077 early in the experiment: he looks out for his fellow prisoners' wellbeing, and they voluntarily follow his lead. Negative leadership is demonstrated by the dominant guards, who escalate punishment and psychological humiliation; other guards follow them not out of agreement but out of fear of exclusion or loss of payment.
Q: How does the experiment director function as a leader, even though he is not directly present in the groups?
A: The director exercises structural leadership by designing the experiment's conditions: selecting participants based on psychological profiles, assigning them to roles that conflict with their dispositions, setting the rules, and using financial incentives to ensure compliance. He shapes behaviour through the situation he creates, not through direct orders within the groups.
Q: Explain how Participant 077 transitions from positive to negative leadership. What situational factors drive the change?
A: 077 begins as a prosocial leader, caring for his peers. As the guards' abuse intensifies, and particularly after his friend (now a guard) betrays their relationship by treating him as just another prisoner, 077 loses trust in the system. The combination of sustained oppression, personal betrayal, and the guards' refusal to recognise the artificiality of the roles pushes 077 to organise a violent revolt, making him a negative leader who channels collective anger into destructive action.
Q: Why did guards who disagreed with the dominant faction continue to comply, at least initially?
A: Several factors: role pressure (the assigned authority role creates expectations of solidarity), the monetary incentive (losing payment if the experiment fails), and the social cost of dissent within a small group. Compliance persisted until the moral cost of going along exceeded these pressures, at which point support was withdrawn and the group disintegrated.
This material connects to Group Theory and Group Dynamics (Part 1): leadership is inseparable from the group's developmental stage. A leader emerges, succeeds, or fails in the context of group norms, conflict, and cohesion.
It also connects to Environmental Psychology (Part 3): the physical environment (confined spaces, surveillance, lack of daylight) amplifies the role pressure that drives leadership shifts.
More broadly, these themes relate to Milgram's obedience studies (following authority), Zimbardo's Stanford Prison Experiment (role absorption), and Bandura's work on moral disengagement.
