P2.S.2Obedience: Milgram's agency theory; the legitimate authority and agentic state; the role of buffers and proximity

Stanley Milgram (1963) ran the most famous study in psychology to investigate obedience to authority — willingness to follow orders from a person perceived as legitimate, even when those orders cause harm.

Milgram's procedure

40 male volunteers (recruited via newspaper ad, paid $4.50) at Yale University were told they were taking part in a study on memory. By rigged "lottery" each was assigned the role of "Teacher"; a confederate was the "Learner." The Learner sat in another room with electrodes attached. The Teacher read word pairs and "shocked" the Learner for each wrong answer, increasing the voltage by 15 V each time, from 15 V ("Slight Shock") up to 450 V ("Danger: Severe Shock — XXX").

No real shocks were given. The Learner protested at 150 V, screamed at 285 V, then fell silent at 315 V. If the Teacher hesitated, the experimenter (in a grey lab coat) used four standardised "prods": "Please continue" → "The experiment requires that you continue" → "It is absolutely essential that you continue" → "You have no other choice; you must go on."

Findings

• 65% of participants administered the maximum 450 V.
• 100% went to at least 300 V (after which the Learner fell silent).
• Many participants showed extreme stress (sweating, trembling, nervous laughter); 3 had seizures.

The study shocked psychology. Ordinary people, faced with a perceived legitimate authority, will inflict apparent harm.

Agency theory

Milgram proposed that we operate in two psychological states:

• Autonomous state: we act according to our own conscience, take responsibility for our actions.
• Agentic state: we see ourselves as agents of an authority figure; the authority is responsible. The shift to the agentic state is called the agentic shift.

The agentic shift is supported by:

• A legitimate authority (lab coat, Yale University).
• Visible symbols of authority (uniform, title, setting).
• Diffusion of responsibility ("I was just following orders" — the Nuremberg defence).

Buffers and proximity

Milgram's variations isolated factors:

• Proximity to learner: when Teacher and Learner were in the same room, obedience fell to 40%; when Teacher had to physically place Learner's hand on the plate, obedience fell to 30%.
• Proximity to authority: when the experimenter gave orders by phone, obedience dropped to 21%.
• Location: in a run-down office (not Yale), obedience fell to 48% — slightly less legitimacy.
• Uniform: when the experimenter wore everyday clothes, obedience fell to 20%.

Buffers (psychological barriers — closed door, distance) make obedience easier; their removal increases conscience-driven refusal.

Strengths and weaknesses

Strengths:

• Carefully designed and replicated (Burger, 2009 found broadly similar levels of obedience).
• Variations isolated specific causal factors.
• High historical impact — explained Holocaust-era atrocities in psychological terms.

Weaknesses:

• Severe ethical issues: deception, distress, no clear right to withdraw.
• Sample bias (volunteer, all male).
• Lab setting may have produced obedience because participants trusted Yale not to harm anyone.
• Some debate over whether participants really believed the shocks were real.
