Obedience: Milgram and Situational Variables

Obedience is a form of social influence in which a person follows a direct order, usually from someone with perceived authority. In 1963, Stanley Milgram ran the most famous test of obedience in psychology, motivated by a real question: how could ordinary people carry out the atrocities of the Holocaust?

Milgram recruited 40 male American volunteers through a newspaper advertisement, aged 20 to 50, each paid $4.50. On arrival, roles were rigged by a fixed draw so that the naive participant was always the "Teacher" and a confederate — a mild-mannered man called "Mr Wallace" — was always the "Learner".

The Teacher was told to give the Learner an electric shock every time he made a mistake on a word-pair task. The shocks were fake, but the participant did not know this. A second confederate, the experimenter, wore a grey lab coat and sat in the room to give orders.

The study is a landmark because it moved obedience from anecdote to controlled measurement. Its findings, and the ethical debate around them, are assessable in both AO1 (describe) and AO3 (evaluate) form.

The shock generator had 30 switches rising in 15V steps from 15V to 450V, labelled from "Slight Shock" to "Danger: Severe Shock" and finally "XXX". Each time the Learner made a mistake, the Teacher was told to move up one level. As the "voltage" rose, the Learner (on a tape recording) protested, screamed, complained of a heart condition, and eventually fell silent.

Whenever the participant hesitated, the experimenter delivered one of four standardised verbal prods, in order:

Order	Prod
1	"Please continue."
2	"The experiment requires that you continue."
3	"It is absolutely essential that you continue."
4	"You have no other choice, you must go on."

The findings were striking:

• 100% of participants continued to at least 300V.
• 65% continued all the way to the maximum 450V.

Many participants showed extreme distress — sweating, trembling, stuttering and nervous laughter — yet still obeyed. Milgram concluded that ordinary people will obey orders from a legitimate authority figure, even to the point of seriously harming another person.

Milgram ran further variations (published 1974) to test which features of the situation drive obedience. Three are named on the AQA specification: proximity, location and uniform.

Proximity is how physically close the people involved are. As the Teacher was brought closer to the consequences of their actions, obedience fell.

Variation	Obedience to 450V
Baseline (learner in next room)	65%
Same room as the learner	40%
Touch proximity (forcing the learner's hand onto the plate)	30%
Experimenter gives orders by telephone	20.5%

Location: moving the study from prestigious Yale University to a run-down office building lowered obedience to 47.5%. This is a comparatively small drop, suggesting the setting still carried some perceived legitimacy.

Uniform: in a variation where the experimenter was called away and replaced by an "ordinary member of the public" in everyday clothes, obedience fell to 20%. This supports the idea that uniform acts as a powerful symbol of legitimate authority.

Support for uniform comes from Bickman (1974), a field experiment in New York. Members of the public were far more likely to obey a confederate dressed as a security guard than the same request from a confederate in a suit.

Milgram proposed that obedience occurs because people enter an agentic state: they act as an "agent" carrying out the wishes of an authority figure, and so feel no personal responsibility for the consequences. Responsibility is displaced onto the person giving the orders.

The opposite is the autonomous state, in which a person acts under their own free will and feels responsible for their own behaviour.

• Agentic shift — the move from autonomous to agentic that happens when a person encounters a figure they perceive as an authority.
• Binding factors — aspects of the situation that allow the person to ignore or minimise the damaging effect of their behaviour, keeping them locked in the agentic state (for example, the shared responsibility with the experimenter or the awkwardness of breaking off).

The agentic state is often given as a reason participants obeyed despite their distress: they believed the experimenter, not themselves, was responsible for any harm to Mr Wallace.

This explains why participants who asked "who is responsible?" would frequently continue once the experimenter answered that he would take responsibility.

The second explanation is legitimacy of authority: we are more likely to obey people we perceive to have authority over us. That authority is justified by the person's position in a social hierarchy that society agrees on — for example, parents, teachers, police officers and, in the study, a scientist at a respected university.

Because we accept this hierarchy, we hand over some of our independence to those we see as legitimate authorities. Some of them, such as police officers, are also granted the power to punish, which strengthens obedience.

A serious problem arises with destructive authority: when a legitimate authority uses that granted power for cruel or dangerous ends. Milgram's experimenter is an example — participants obeyed instructions that appeared to be harming another person because the orders came from a legitimate scientific authority.

Concept	What it explains
Legitimacy of authority	Why we obey certain people at all — their agreed place in a hierarchy
Destructive authority	Why legitimate power can lead to harm — the authority orders cruelty
Agentic state	The mental state that lets us continue once we have begun to obey

Distinguish the two explanations carefully. Legitimacy of authority explains why a person begins to obey; the agentic state describes the mental condition that keeps them obeying.

Research support for the situational explanation. The variations themselves, plus Bickman's (1974) uniform field experiment, show that features of the situation reliably change obedience. Cross-cultural replications add weight: Miranda et al. reported obedience over 90% in Spanish students. However, Mandel (1998) argues situational explanations are dangerous because they can be used to excuse harmful behaviour, offering an "obedience alibi" that removes responsibility from the perpetrator.

A debate over internal validity. Orne and Holland argued participants saw through the deception and only played along because they knew the shocks were fake. Against this, Milgram reported that over 70% of participants said they believed the shocks were genuine. Sheridan and King gave participants real (not fake) shocks to a live puppy and still found 54% of men and 100% of women obeyed fully — supporting the idea that the obedience Milgram observed was genuine.

Legitimacy of authority explains cultural differences. Obedience rates vary by country. Kilham and Mann found only 16% of Australian women went to the top of the scale, far lower than rates elsewhere. Differences like this reflect how far different cultures are structured around respect for authority, which the legitimacy explanation predicts.

Ethical issues. Milgram's study involved deception (about the shocks and roles), a lack of fully informed consent, and psychological harm given the visible distress. The right to withdraw was also compromised: the standardised prods actively discouraged participants from stopping. These issues must be weighed against the study's contribution to understanding obedience.

1. Saying 65% obeyed "at every level"

The 65% figure is the proportion who continued to the maximum 450V. It is 100% who reached at least 300V. Stating that 65% obeyed throughout, or that 65% reached 300V, misreports the two headline findings.

2. Confusing agentic state with legitimacy of authority

Legitimacy of authority explains why a person obeys an authority figure (their place in a social hierarchy). The agentic state is the mental state of acting as an agent with no personal responsibility. Define each separately and do not treat them as the same idea.

3. Confusing situational and dispositional explanations

Proximity, location and uniform are situational variables studied by Milgram. The Authoritarian Personality is the separate dispositional explanation. A question on situational variables must not drift into personality-based obedience.

4. Muddling the proximity figures

Keep the numbers straight: same room = 40%, touch proximity = 30%, telephone instructions = 20.5%. A common error is to swap these or to confuse them with the location (47.5%) and uniform (20%) variations.

5. Treating distress as disobedience

Participants who sweated, trembled or laughed nervously still obeyed. Signs of tension are not the same as refusing; the striking finding is that people continued despite their obvious distress.
