Stanley Milgram

American social psychologist (1933–1984)

Stanley Milgram: The Man Who Measured Obedience

In the basement of Linsly-Chittenden Hall at Yale in 1961, three months after Adolf Eichmann's trial opened in Jerusalem, ordinary New Haven residents were asked to deliver what they believed were escalating electric shocks to a stranger. Roughly sixty-five per cent went all the way to the maximum. The experiment made Stanley Milgram the most famous social psychologist of the century and, for the rest of his life, one of the most criticised.

A Bronx Childhood Under the Shadow of Europe

Stanley Milgram was born on 15 August 1933 in the Bronx, New York City, the second of three children of Adele and Samuel Milgram, Jewish immigrants who had come from Romania and Hungary during the First World War. The Holocaust was not an abstraction in that household: relatives who survived the Nazi camps stayed with the family after the war. His 1946 Bar Mitzvah speech was about the suffering of European Jews. Later he wrote a sentence that explains almost his entire research programme: "I should have been born into the German-speaking Jewish community of Prague in 1922 and died in a gas chamber some 20 years later."

He attended James Monroe High School in the Bronx, where a classmate was Philip Zimbardo — the two most notorious experimentalists in the field's history sitting in the same building.

An Unlikely Psychologist

Milgram took a bachelor's degree in political science at Queens College in 1954. Harvard initially rejected his application to study social psychology on the grounds that he had insufficient background in the subject; he was admitted subsequently and received his PhD in 1960. That autumn he became an assistant professor at Yale, where the obedience work was done. He returned to Harvard's Department of Social Relations as an assistant professor from 1963 to 1966, on a three-year contract extended by a year as lecturer, and was not given tenure. In 1967 the City University of New York Graduate Center made him a tenured full professor, a post he held until his death.

The Obedience Experiments

The design was deceptively simple. Subjects believed they were participating in a study of memory and learning, acting as "teachers" who administered increasingly severe shocks to "learners" — confederates — for wrong answers. The learners were not being shocked. The teachers did not know that, and roughly two-thirds continued to the maximum voltage despite the apparent suffering.

Milgram's explanation was the "agentic state": the condition in which, as he put it, "a person comes to view himself as the instrument for carrying out another person's wishes, and he therefore no longer sees himself as responsible for his actions." He published "Behavioral Study of Obedience" in the *Journal of Abnormal and Social Psychology* in 1963 and the full account, *Obedience to Authority: An Experimental View*, in 1974. The American Association for the Advancement of Science gave him its prize for behavioural science research in 1964.

Six Degrees

In 1967 Milgram ran the small-world experiment, sending packages to 160 randomly chosen people in Omaha, Nebraska, who were instructed to forward them towards a target stockbroker in Boston — but only via people they knew on a first-name basis. Completed chains ran from two to ten intermediaries with a median of five, which is to say six degrees of separation. One package arrived in four days.

The result entered the language, and the criticism has never gone away: many packages went untracked, and later work questioned the validity of the six-degrees claim. A 2008 Microsoft study of Messenger users found an average chain of 6.6 — vindication of a sort, four decades late.

Letters and Cyranoids

The lost-letter technique was his most elegant invention: seal stamped letters, address them variously to individuals, to sympathetic organisations such as medical research institutes, and to stigmatised ones such as "Friends of the Nazi Party," then scatter them in public and count what gets posted. Letters to individuals and respectable causes came back; letters to the Nazis largely did not. It measured collective attitudes without asking anyone a single question. A 2024 meta-analysis of 78 such experiments across 18 countries found a 50 per cent average return rate.

Between 1977 and 1984 he developed the cyranoid technique, named for Cyrano de Bergerac: a speech-shadower repeats words fed by a remote source over radio, producing a hybrid social agent. Conversation partners almost never detected it, attributing full autonomy to the shadower — the "cyranic illusion." The London School of Economics published the first formal replications in 2014.

The Ethics Fight

The American Psychological Association delayed his membership application by a year over ethical objections to the obedience studies. Critics argued that subjects had been subjected to genuine psychological distress, that some may not have believed the deception, and that laboratory findings said little about real-world atrocity. Milgram's counter went to the heart of the matter: "Underlying the criticism of the experiment is an alternative model of human nature, one holding that when confronted with a choice between hurting others and complying with authority, normal people reject authority." The complaint, in other words, was partly about the result.

Why Stanley Is Called a Genius

Milgram's distinctive faculty was experimental design — the ability to convert a vast, unmeasurable moral question into a procedure that produces a number. Nobody before him had found a way to put obedience on a dial, or social distance on a count of intermediaries, or public prejudice into a postal return rate. The lost-letter technique in particular is close to a perfect instrument: unobtrusive, cheap, and immune to the thing that ruins attitude surveys, which is that people lie about their attitudes. His biographer Thomas Blass attributed the focus of the research to Milgram's lifelong identification with the Jewish people, and the historian Kirsten Fermaglich described his position as a personal conflict between being an outsider, a victim of the Nazi destruction, and an insider, a scientist. The genius was in the translation between those two selves.

The counter-case is serious and permanent. The obedience studies rest on deception and inflicted distress in ways no ethics board would now approve; the six-degrees finding was under-documented and over-claimed; and critics have long argued that the agentic state explains less than Milgram thought, and that demand characteristics of the laboratory contaminate the result. He was also, by the standards of his field, a poor theorist — the ideas he built on top of his data have aged worse than the data. What survives is the instrument-making. He was ranked the forty-sixth most-cited psychologist of the twentieth century, and the studies are still argued about sixty years on, which is itself the measure.

Legacy

Milgram died in New York City on 20 December 1984, aged 51, of a heart attack — his fifth. He had married Alexandra in December 1961 at the Brotherhood Synagogue in Greenwich Village; they had two children, Michele and Marc, and were living in New Rochelle. His findings have been used to explain police interrogation tactics that yield false confessions and the dynamics behind the My Lai massacre of 1968. He became a rare psychologist absorbed into popular culture: the 1975 CBS film *The Tenth Level* with William Shatner, on which he consulted; Peter Gabriel's song "We Do What We're Told (Milgram's 37)"; and *Experimenter* (2015), with Peter Sarsgaard as Milgram. Few researchers have produced a result that ordinary people can still state accurately six decades later. Fewer still have produced one they would rather not know.
