obedience experiment

A landmark series of social-psychology studies conducted by Stanley Milgram at Yale University beginning in 1961, testing how far ordinary people would obey an authority figure instructing them to harm another person. Participants were directed to administer what they believed were increasingly severe electric shocks to a “learner” for wrong answers, while an experimenter insisted they continue. In reality the “learner” was a confederate (an actor), and no real shocks were ever delivered — but the participants believed the shocks were genuine, which is what the study measured.

Core finding: roughly two-thirds of participants (about 65%) continued to the highest, apparently lethal 450-volt level simply because an authority figure told them to — even while showing visible distress. Beforehand, psychiatrists had predicted only about 0.1% would go that far. The result overturned the assumption that only unusual or “evil” people inflict serious harm, showing instead that the situation — pressure from a legitimate-seeming authority — can override individual character. Milgram explained this through the “agentic state”: under authority, people shift moral responsibility upward and stop seeing themselves as the author of their own actions. The effect has proven robust across cultures and decades, with modern replications still finding 70–90% compliance.

Why it matters: the studies offer a framework for how ordinary people come to take part in institutional harm — from the conduct of Nazi units (Milgram framed the work partly in response to the Holocaust and the Eichmann trial) to everyday cases of people obeying an illegitimate “authority.” The controversy over the distress it caused participants also helped create the modern human-subjects protection system (informed consent, review boards). Its reach is broad: it is cited across law and the social sciences, and — per the Association for Psychological Science — the U.S. Army has required cadets to study it and its implications.

Limitations: the studies are also heavily debated — later archival work (Perry, 2013) found the experimenters sometimes improvised pressure beyond the written script, many participants may have doubted the shocks were real, and the sample was all-male and self-selected.
