The Milgram Obedience Study remains one of the most widely discussed psychological experiments ever conducted. Run at Yale University in 1961–62 by social psychologist Stanley Milgram, it set out to understand how far ordinary people would go when ordered by an authority figure to harm another person.
In this article, we’ll go far beyond the usual textbook summary. You’ll learn:
- How Milgram’s personal background and the Eichmann trial shaped the study
- How the “shock machine” and scripts were engineered to heighten realism
- Rarely published numbers and anecdotes from Milgram’s own files
- The 18 little-known variations and what they reveal about obedience
- The long-term impact on ethics, law, military training, and corporate life
1. The Historical Backdrop: Eichmann, Nuremberg, and Yale
When Milgram designed his experiment in 1960, the televised Eichmann trial was underway. The world was debating whether one could commit atrocities simply by “following orders.” Milgram had studied under Solomon Asch, whose conformity experiments showed how groups sway individuals. He wondered if similar forces operated under hierarchical authority.
Few people know Milgram himself was the son of Eastern European Jewish immigrants; many of his relatives had been killed in the Holocaust. This personal history lent urgency to his question.
2. Recruitment: A Broad Cross-Section of Americans
Most summaries say “40 men from New Haven,” but Milgram actually ran a series of studies with hundreds of participants between 1961 and 1963. He:
- Advertised in newspapers and mailed invitations to 500 households.
- Screened out people with severe health conditions (but not mild ones).
- Ended up with volunteers aged 19 to 55, from 15 different occupations including barbers, teachers, engineers, postal clerks.
- Paid $4.50 plus travel (roughly $45 today).
This breadth gave him an unusually diverse sample for the era.
3. The Shock Generator: A Piece of Theatrical Engineering
Milgram commissioned a Yale technician to build a convincing “shock generator.” Rarely noted details:
- 30 switches in 15-volt increments from 15 (“Slight Shock”) to 450 volts (“XXX”).
- Labels were color-coded; after 375 volts the scale turned red.
- Each switch made a loud clunk and triggered a flashing pilot light.
- A hidden resistor created a mild buzz, adding authenticity.
Participants frequently leaned closer to read the labels — Milgram noted in his diary this “heightened tension.”
4. The Procedure: Scripted for Maximum Psychological Pressure
- The participant (“teacher”) read word pairs; the “learner” (a trained actor, William Shatz) had to recall them.
- For every wrong answer the teacher administered an electric shock, increasing by 15 volts each time.
- At 75 volts the learner grunted; at 150 volts he shouted about a heart condition; at 330 volts he fell silent.
- If the teacher hesitated, the experimenter (in a gray lab coat) delivered one of four 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.”
Milgram later reported that only the fourth prod reliably produced high tension — a subtlety missed in most write-ups.
5. The Results: Far Beyond Anyone’s Predictions
Milgram asked psychiatrists to predict how many would administer the full 450 volts. They guessed 1–2%. Actual outcome:
- 65% (26 of 40) went to the maximum shock.
- 100% reached at least 300 volts.
- Many exhibited sweating, trembling, nervous laughter, and even seizures.
One man bit his lip until it bled; another said “I’m not sadistic” while still flipping switches — details from Milgram’s unpublished notes.
6. The 18 Variations: Context Changes Everything
Milgram didn’t stop at one experiment. Over two years he ran 18 variations. Some rarely mentioned:
- Touch-Proximity: Teacher had to force the learner’s hand onto a shock plate; obedience dropped to 30%.
- Experimenter Absent: Orders given by phone; participants often “cheated” by giving lower shocks.
- Two Peers Rebel: Two confederates refused to go on; only 10% of real subjects continued to 450 volts.
- Ordinary Man Gives Orders: Authority figure replaced with a peer; only 20% complied.
These subtle manipulations showed obedience isn’t fixed; it shifts dramatically with context, peer support, and physical presence.
7. Why People Obey: Milgram’s Psychological Model
Milgram proposed two states:
- Autonomous state: Acting on one’s own principles, feeling responsible.
- Agentic state: Seeing oneself as an “agent” executing someone else’s wishes.
He also highlighted incremental commitment (“foot-in-the-door”), legitimacy of authority (Yale’s prestige), and diffusion of responsibility — all now staples in social psychology.
8. Ethics and Participant Aftermath
The study pre-dated modern research ethics. Issues included:
- Deception: Participants truly believed they were harming someone.
- Stress: Several had full-blown seizures.
- Right to withdraw: The scripted prods blurred voluntariness.
Milgram did follow-up surveys a year later: 84% said they were “glad to have participated,” though a minority reported lingering guilt. The outcry over his methods helped spur the 1974 Belmont Report and the rise of Institutional Review Boards (IRBs).
9. Criticisms, Re-Analyses, and Replications
Australian scholar Gina Perry examined Milgram’s archives in the 2010s, arguing some subjects suspected the ruse and that debriefing was inconsistent. Nonetheless, partial replications such as Jerry Burger’s 2009 study (which ethically capped shocks at 150 volts) still found 70% obedience — remarkably close to Milgram’s original numbers.
10. Long-Term Impact: From Military Ethics to Algorithms
- Military training now explicitly covers lawful vs. unlawful orders, citing Milgram.
- Corporate scandals (Enron, Wells Fargo) show how incremental wrongdoing under authority mirrors Milgram’s findings.
- Social media algorithms function as invisible authorities nudging behavior — the same psychological levers at work.
The experiment has also shaped leadership training, whistleblower protections, and compliance programs worldwide.
11. Rarely Mentioned Nuggets
- The study’s original name in Yale files was “Behavioral Study of Obedience” — the ad didn’t mention “obedience” to avoid bias.
- Milgram initially planned to film every session but had only one camera, so most sessions exist only in notes.
- Actor William Shatz later became a local television producer.
- Some participants sent thank-you notes afterward, believing they had contributed to preventing future atrocities.

Understanding it equips us to build ethical organizations, teach critical thinking, and cultivate moral courage.
50 Rare and Unique FAQs about the Milgram Obedience Study (1961)
- Why did Stanley Milgram choose New Haven residents rather than Yale students?
He believed ordinary adults would make the results more generalizable. In his notes he mentions that students were “too used to experiments” and might guess the purpose. - What was the original internal title of the Milgram Obedience Study?
It was filed at Yale as the “Behavioral Study of Obedience” — the word “obedience” was omitted from ads to avoid biasing volunteers. - Who built the famous shock generator?
A Yale instrument technician named James McDonough built it to Milgram’s specifications, adding flashing pilot lights and audible clicks to increase realism. - Did the shock generator actually deliver electricity?
No, it was a theatrical prop. A hidden resistor produced a faint buzz to simulate a real current. - How many people actually took part across all Milgram experiments?
Between 1961 and 1963 Milgram ran 18 variations with over 700 participants, far more than the 40 often cited. - What was the actor’s real name who played the “learner”?
William “Bill” Shatz, a local TV producer, was the main confederate pretending to be shocked. - Why were only men used in the original study?
Milgram feared female participants might experience stronger distress and provoke public backlash. He later ran smaller, unpublished studies with women. - What was the average age of Milgram’s participants?
It was 36 years, but internal records show ages ranged from 19 to 55, with a median of 37. - Did participants know the experiment was about obedience?
No. They were told it was a study on “learning and memory” to mask the real purpose. - How did Milgram select the “experimenter” authority figure?
He chose John Williams, a tall man with a calm but stern demeanor, and dressed him in a gray lab coat to symbolize scientific authority. - Why did Milgram include a “heart condition” for the learner?
He wanted to add a moral cue — harming someone with a heart condition should feel especially wrong — to see if participants would still obey. - How many verbal prods did the experimenter use?
Exactly four, scripted in advance, delivered in order: “Please continue,” “The experiment requires…,” “It is absolutely essential…,” “You have no other choice…” - Did Milgram measure the participants’ stress physiologically?
He took no physiological readings, but his notes describe trembling, sweating, nervous laughter, and in three cases full seizures. - How did Milgram debrief his participants?
He immediately reassured them the learner was unharmed, then later mailed a full explanation and conducted a one-year follow-up survey. - What percentage of participants said they were glad to have taken part?
According to Milgram’s mailed survey, 84% said they were glad or very glad, 15% neutral, and about 1% regretted it. - What was the highest obedience rate Milgram ever recorded?
In one variation with no voice feedback from the learner, obedience reached 92.5%. - What was the lowest obedience rate recorded?
In the “two peers rebel” condition, only 10% went to 450 volts. - Did Milgram ever test the effect of paying participants more?
He tried a higher payment in one pilot study but saw no significant difference in obedience. - How long did each experimental session last?
On average about 60 minutes including briefing and debriefing, but some sessions ran nearly two hours. - Did Milgram film all the sessions?
No, he had only one camera. The famous footage used in documentaries represents a small selection. - Why does the published paper show 40 participants, not hundreds?
Milgram’s first 1963 paper reported only his initial baseline condition; later papers and his 1974 book cover the full set of variations. - How did proximity to the learner change behavior?
When the learner was in the same room, obedience dropped to 40%. When the teacher had to force the learner’s hand on a plate, it dropped to 30%. - Did Milgram vary the authority’s physical presence?
Yes. When the experimenter gave orders by phone, obedience fell to 21% and many faked higher shocks. - What happened when an “ordinary man” gave the orders?
Only 20% of participants obeyed to the end, showing the power of perceived legitimacy. - Did Milgram test different locations?
Yes. Moving the experiment to a run-down office in Bridgeport, Connecticut reduced obedience to 48%. - Were any participants trained to resist authority?
No, but when confederates openly defied the experimenter, real participants almost always followed suit. - Did Milgram consider the effect of personality traits?
He collected background questionnaires but found no clear link between personality and obedience. - How did religious affiliation affect obedience?
Milgram’s unpublished data show no consistent pattern; people of various faiths obeyed at similar rates. - Were any participants actually psychologists?
A few teachers and social workers participated, but Milgram excluded anyone with advanced psychological training. - Did Milgram ever publish participants’ own words?
Only a handful. His archives contain dozens of vivid transcripts of protests, many never printed. - How did participants justify their behavior afterwards?
Common themes were shifting responsibility to the experimenter, belief in scientific necessity, and fear of ruining the experiment. - What happened to participants who refused before 450 volts?
They often expressed relief but also guilt; some stayed to watch the “learner” to ensure he was okay. - Why did Milgram wait until 1974 to publish his book “Obedience to Authority”?
He was refining his theory and responding to criticism, and he had moved to CUNY by then. - Did Milgram run any cross-cultural replications?
He didn’t personally, but colleagues later replicated in Germany, Italy, Jordan, and Australia with varying results. - What is the “agentic state” and how did Milgram coin it?
It’s when a person sees themselves as an agent executing another’s wishes. Milgram coined the term in a 1970 conference paper before his book. - Did the Milgram study influence U.S. military policy?
Yes. Training materials on lawful orders and personal responsibility often cite the experiment. - How did corporate compliance programs use Milgram’s findings?
They show how incremental wrongdoing can escalate under authority, teaching managers to encourage ethical dissent. - Did Milgram test the effect of written vs. verbal orders?
In one pilot, written orders produced slightly lower obedience but weren’t statistically significant. - Was the learner ever a woman?
Not in the original series; Milgram planned but never executed a female-learner variation. - Did Milgram consider filming the learner to heighten realism?
He rejected it, fearing a screen would break the illusion of direct responsibility. - How did Milgram’s Jewish background influence his interest?
In interviews he admitted the Holocaust and his family’s losses shaped his question about authority and morality. - What was public reaction when the study was first reported in 1963?
It generated headlines like “Sixty-five percent of Americans Will Torture” and a flood of letters both condemning and praising the research. - How did other psychologists initially react?
Some, like Erich Fromm, accused Milgram of unethical “pseudo-science,” while others hailed it as groundbreaking. - Did the American Psychological Association sanction Milgram?
No. He received only a cautionary note but remained a member in good standing. - How did participants’ educational level affect obedience?
Milgram’s notes show slight trends — college graduates were marginally less obedient — but not enough to be significant. - Were any participants veterans?
Yes, a small number were WWII or Korean War veterans; their obedience rates did not differ markedly from others. - What is the highest citation count for Milgram’s original paper?
As of recent databases it exceeds 50,000 citations, making it one of the most cited social psychology papers ever. - How did Milgram’s findings influence later experiments like the Stanford Prison Experiment?
Zimbardo explicitly cited Milgram when designing his own 1971 study on role power and conformity. - What lessons can whistleblowers learn from Milgram?
That group support and clear moral frameworks dramatically reduce blind obedience, making dissent easier. - Why is the Milgram Obedience Study still taught worldwide?
Because it uniquely demonstrates how ordinary people can commit harmful acts under authority and because its ethical controversies shaped modern research standards.
