Stanley Milgram, a psychologist at Yale University, carried out one of the most famous studies of obedience in psychology.
He conducted an experiment focusing on the conflict between obedience to authority and personal conscience.
Milgram (1963) examined justifications for acts of genocide offered by those accused at the World War II, Nuremberg War Criminal trials. Their defense often was based on obedience – that they were just following orders from their superiors.
The experiments began in July 1961, a year after the trial of Adolf Eichmann in Jerusalem. Milgram devised the experiment to answer the question:
Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices?” (Milgram, 1974).
Milgram (1963) wanted to investigate whether Germans were particularly obedient to authority figures, as this was a common explanation for the Nazi killings in World War II.
Milgram selected participants for his experiment by newspaper advertising for male participants to take part in a study of learning at Yale University.
The procedure was that the participant was paired with another person and they drew lots to find out who would be the ‘learner’ and who would be the ‘teacher.’ The draw was fixed so that the participant was always the teacher, and the learner was one of Milgram’s confederates (pretending to be a real participant).
The learner (a confederate called Mr. Wallace) was taken into a room and had electrodes attached to his arms, and the teacher and researcher went into a room next door that contained an electric shock generator and a row of switches marked from 15 volts (Slight Shock) to 375 volts (Danger: Severe Shock) to 450 volts (XXX).
The shocks in Stanley Milgram’s obedience experiments were not real. The “learners” were actors who were part of the experiment and did not actually receive any shocks.
However, the “teachers” (the real participants of the study) believed the shocks were real, which was crucial for the experiment to measure obedience to authority figures even when it involved causing harm to others.
Milgram’s Experiment (1963)
Milgram (1963) was interested in researching how far people would go in obeying an instruction if it involved harming another person.
Stanley Milgram was interested in how easily ordinary people could be influenced into committing atrocities, for example, Germans in WWII.
Volunteers were recruited for a controlled experiment investigating “learning” (re: ethics: deception).
Participants were 40 males, aged between 20 and 50, whose jobs ranged from unskilled to professional, from the New Haven area. They were paid $4.50 for just turning up.
At the beginning of the experiment, they were introduced to another participant, a confederate of the experimenter (Milgram).
They drew straws to determine their roles – learner or teacher – although this was fixed, and the confederate was always the learner. There was also an “experimenter” dressed in a gray lab coat, played by an actor (not Milgram).
Two rooms in the Yale Interaction Laboratory were used – one for the learner (with an electric chair) and another for the teacher and experimenter with an electric shock generator.
The “learner” (Mr. Wallace) was strapped to a chair with electrodes.
After he has learned a list of word pairs given to him to learn, the “teacher” tests him by naming a word and asking the learner to recall its partner/pair from a list of four possible choices.
The teacher is told to administer an electric shock every time the learner makes a mistake, increasing the level of shock each time. There were 30 switches on the shock generator marked from 15 volts (slight shock) to 450 (danger – severe shock).
The learner gave mainly wrong answers (on purpose), and for each of these, the teacher gave him an electric shock. When the teacher refused to administer a shock, the experimenter was to give a series of orders/prods to ensure they continued.
There were four prods, and if one was not obeyed, then the experimenter (Mr. Williams) read out the next prod, and so on.
Prod 1 : Please continue. Prod 2: The experiment requires you to continue. Prod 3 : It is absolutely essential that you continue. Prod 4 : You have no other choice but to continue.
These prods were to be used in order, and begun afresh for each new attempt at defiance (Milgram, 1974, p. 21). The experimenter also had two special prods available. These could be used as required by the situation:
- Although the shocks may be painful, there is no permanent tissue damage, so please go on’ (ibid.)
- ‘Whether the learner likes it or not, you must go on until he has learned all the word pairs correctly. So please go on’ (ibid., p. 22).
65% (two-thirds) of participants (i.e., teachers) continued to the highest level of 450 volts. All the participants continued to 300 volts.
Milgram did more than one experiment – he carried out 18 variations of his study. All he did was alter the situation (IV) to see how this affected obedience (DV).
Conclusion
The individual explanation for the behavior of the participants would be that it was something about them as people that caused them to obey, but a more realistic explanation is that the situation they were in influenced them and caused them to behave in the way that they did.
Some aspects of the situation that may have influenced their behavior include the formality of the location, the behavior of the experimenter, and the fact that it was an experiment for which they had volunteered and been paid.
Ordinary people are likely to follow orders given by an authority figure, even to the extent of killing an innocent human being. Obedience to authority is ingrained in us all from the way we are brought up.
People tend to obey orders from other people if they recognize their authority as morally right and/or legally based. This response to legitimate authority is learned in a variety of situations, for example in the family, school, and workplace.
Milgram summed up in the article “The Perils of Obedience” (Milgram 1974), writing:
“The legal and philosophic aspects of obedience are of enormous import, but they say very little about how most people behave in concrete situations. I set up a simple experiment at Yale University to test how much pain an ordinary citizen would inflict on another person simply because he was ordered to by an experimental scientist. Stark authority was pitted against the subjects’ [participants’] strongest moral imperatives against hurting others, and, with the subjects’ [participants’] ears ringing with the screams of the victims, authority won more often than not. The extreme willingness of adults to go to almost any lengths on the command of an authority constitutes the chief finding of the study and the fact most urgently demanding explanation.”
Milgram’s Agency Theory
Milgram (1974) explained the behavior of his participants by suggesting that people have two states of behavior when they are in a social situation:
- The autonomous state – people direct their own actions, and they take responsibility for the results of those actions.
- The agentic state – people allow others to direct their actions and then pass off the responsibility for the consequences to the person giving the orders. In other words, they act as agents for another person’s will.
Milgram suggested that two things must be in place for a person to enter the agentic state:
- The person giving the orders is perceived as being qualified to direct other people’s behavior. That is, they are seen as legitimate.
- The person being ordered about is able to believe that the authority will accept responsibility for what happens.
According to Milgram, when in this agentic state, the participant in the obedience studies “defines himself in a social situation in a manner that renders him open to regulation by a person of higher status. In this condition the individual no longer views himself as responsible for his own actions but defines himself as an instrument for carrying out the wishes of others” (Milgram, 1974, p. 134).
Agency theory says that people will obey an authority when they believe that the authority will take responsibility for the consequences of their actions. This is supported by some aspects of Milgram’s evidence.
For example, when participants were reminded that they had responsibility for their own actions, almost none of them were prepared to obey.
In contrast, many participants who were refusing to go on did so if the experimenter said that he would take responsibility.
According to Milgram (1974, p. 188):
“The behavior revealed in the experiments reported here is normal human behavior but revealed under conditions that show with particular clarity the danger to human survival inherent in our make-up.
And what is it we have seen? Not aggression, for there is no anger, vindictiveness, or hatred in those who shocked the victim….
Something far more dangerous is revealed: the capacity for man to abandon his humanity, indeed, the inevitability that he does so, as he merges his unique personality into larger institutional structures.”
Milgram Experiment Variations
The Milgram experiment was carried out many times whereby Milgram (1965) varied the basic procedure (changed the IV). By doing this Milgram could identify which factors affected obedience (the DV).
Obedience was measured by how many participants shocked to the maximum 450 volts (65% in the original study). Stanley Milgram conducted a total of 23 variations (also called conditions or experiments) of his original obedience study:
In total, 636 participants were tested in 18 variation studies conducted between 1961 and 1962 at Yale University.
In the original baseline study – the experimenter wore a gray lab coat to symbolize his authority (a kind of uniform).
The lab coat worn by the experimenter in the original study served as a crucial symbol of scientific authority that increased obedience. The lab coat conveyed expertise and legitimacy, making participants see the experimenter as more credible and trustworthy.
Milgram carried out a variation in which the experimenter was called away because of a phone call right at the start of the procedure.
The role of the experimenter was then taken over by an ‘ordinary member of the public’ ( a confederate) in everyday clothes rather than a lab coat. The obedience level dropped to 20%.
Change of Location: The Mountain View Facility Study (1963, unpublished)
Milgram conducted this variation in a set of offices in a rundown building, claiming it was associated with “Research Associates of Bridgeport” rather than Yale.
The lab’s ordinary appearance was designed to test if Yale’s prestige encouraged obedience. Participants were led to believe that a private research firm experimented.
In this non-university setting, obedience rates dropped to 47.5% compared to 65% in the original Yale experiments. This suggests that the status of location affects obedience.
Private research firms are viewed as less prestigious than certain universities, which affects behavior. It is easier under these conditions to abandon the belief in the experimenter’s essential decency.
The impressive university setting reinforced the experimenter’s authority and conveyed an implicit approval of the research.
Milgram filmed this variation for his documentary Obedience , but did not publish the results in his academic papers. The study only came to wider light when archival materials, including his notes, films, and data, were studied by later researchers like Perry (2013) in the decades after Milgram’s death.
Two Teacher Condition
When participants could instruct an assistant (confederate) to press the switches, 92.5% shocked to the maximum of 450 volts.
Allowing the participant to instruct an assistant to press the shock switches diffused personal responsibility and likely reduced perceptions of causing direct harm.
By attributing the actions to the assistant rather than themselves, participants could more easily justify shocking to the maximum 450 volts, reflected in the 92.5% obedience rate.
When there is less personal responsibility, obedience increases. This relates to Milgram’s Agency Theory.
Touch Proximity Condition
The teacher had to force the learner’s hand down onto a shock plate when the learner refused to participate after 150 volts. Obedience fell to 30%.
Forcing the learner’s hand onto the shock plate after 150 volts physically connected the teacher to the consequences of their actions. This direct tactile feedback increased the teacher’s personal responsibility.
No longer shielded from the learner’s reactions, the proximity enabled participants to more clearly perceive the harm they were causing, reducing obedience to 30%. Physical distance and indirect actions in the original setup made it easier to rationalize obeying the experimenter.
The participant is no longer buffered/protected from seeing the consequences of their actions.
Social Support Condition
When the two confederates set an example of defiance by refusing to continue the shocks, especially early on at 150 volts, it permitted the real participant also to resist authority.
Two other participants (confederates) were also teachers but refused to obey. Confederate 1 stopped at 150 volts, and Confederate 2 stopped at 210 volts.
Their disobedience provided social proof that it was acceptable to disobey. This modeling of defiance lowered obedience to only 10% compared to 65% without such social support. It demonstrated that social modeling can validate challenging authority.
The presence of others who are seen to disobey the authority figure reduces the level of obedience to 10%.
Absent Experimenter Condition
It is easier to resist the orders from an authority figure if they are not close by. When the experimenter instructed and prompted the teacher by telephone from another room, obedience fell to 20.5%.
Many participants cheated and missed out on shocks or gave less voltage than ordered by the experimenter. The proximity of authority figures affects obedience.
The physical absence of the authority figure enabled participants to act more freely on their own moral inclinations rather than the experimenter’s commands. This highlighted the role of an authority’s direct presence in influencing behavior.
A key reason the obedience studies fascinate people is Milgram presented them as a scientific experiment, contrasting himself as an “empirically grounded scientist” compared to philosophers. He claimed he systematically varied factors to alter obedience rates.
However, recent scholarship using archival records shows Milgram’s account of standardizing the procedure was misleading. For example, he published a list of standardized prods the experimenter used when participants questioned continuing. Milgram said these were delivered uniformly in a firm but polite tone.
Analyzing audiotapes, Gibson (2013) found considerable variation from the published protocol – the prods differed across trials. The point is not that Milgram did poor science, but that the archival materials reveal the limitations of the textbook account of his “standardized” procedure.
The qualitative data like participant feedback, Milgram’s notes, and researchers’ actions provide a fuller, messier picture than the obedience studies’ “official” story. For psychology students, this shows how scientific reporting can polish findings in a way that strays from the less tidy reality.
Critical Evaluation
Inaccurate description of the prod methodology:.
A key reason the obedience studies fascinate people is Milgram (1974) presented them as a scientific experiment, contrasting himself as an “empirically grounded scientist” compared to philosophers. He claimed he systematically varied factors to alter obedience rates.
However, recent scholarship using archival records shows Milgram’s account of standardizing the procedure was misleading. For example, he published a list of standardized prods the experimenter used when participants questioned continuing. Milgram said these were delivered uniformly in a firm but polite tone (Gibson, 2013; Perry, 2013; Russell, 2010).
Perry’s (2013) archival research revealed another discrepancy between Milgram’s published account and the actual events. Milgram claimed standardized prods were used when participants resisted, but Perry’s audiotape analysis showed the experimenter often improvised more coercive prods beyond the supposed script.
This off-script prodding varied between experiments and participants, and was especially prevalent with female participants where no gender obedience difference was found – suggesting the improvisation influenced results. Gibson (2013) and Russell (2009) corroborated the experimenter’s departures from the supposed fixed prods.
Prods were often combined or modified rather than used verbatim as published.
Russell speculated the improvisation aimed to achieve outcomes the experimenter believed Milgram wanted. Milgram seemed to tacitly approve of the deviations by not correcting them when observing.
This raises significant issues around experimenter bias influencing results, lack of standardization compromising validity, and ethical problems with Milgram misrepresenting procedures.
Milgram’s experiment lacked external validity:
The Milgram studies were conducted in laboratory-type conditions, and we must ask if this tells us much about real-life situations.
We obey in a variety of real-life situations that are far more subtle than instructions to give people electric shocks, and it would be interesting to see what factors operate in everyday obedience. The sort of situation Milgram investigated would be more suited to a military context.
Orne and Holland (1968) accused Milgram’s study of lacking ‘experimental realism,”’ i.e.,” participants might not have believed the experimental set-up they found themselves in and knew the learner wasn’t receiving electric shocks.
“It’s more truthful to say that only half of the people who undertook the experiment fully believed it was real, and of those two-thirds disobeyed the experimenter,” observes Perry (p. 139).
Milgram’s sample was biased:
- The participants in Milgram’s study were all male. Do the findings transfer to females?
- Milgram’s study cannot be seen as representative of the American population as his sample was self-selected. This is because they became participants only by electing to respond to a newspaper advertisement (selecting themselves).
- They may also have a typical “volunteer personality” – not all the newspaper readers responded so perhaps it takes this personality type to do so.
Yet a total of 636 participants were tested in 18 separate experiments across the New Haven area, which was seen as being reasonably representative of a typical American town.
Milgram’s findings have been replicated in a variety of cultures and most lead to the same conclusions as Milgram’s original study and in some cases see higher obedience rates.
However, Smith and Bond (1998) point out that with the exception of Jordan (Shanab & Yahya, 1978), the majority of these studies have been conducted in industrialized Western cultures, and we should be cautious before we conclude that a universal trait of social behavior has been identified.
Selective reporting of experimental findings:
Perry (2013) found Milgram omitted findings from some obedience experiments he conducted, reporting only results supporting his conclusions. A key omission was the Relationship condition (conducted in 1962 but unpublished), where participant pairs were relatives or close acquaintances.
When the learner protested being shocked, most teachers disobeyed, contradicting Milgram’s emphasis on obedience to authority.
Perry argued Milgram likely did not publish this 85% disobedience rate because it undermined his narrative and would be difficult to defend ethically since the teacher and learner knew each other closely.
Milgram’s selective reporting biased interpretations of his findings. His failure to publish all his experiments raises issues around researchers’ ethical obligation to completely and responsibly report their results, not just those fitting their expectations.
Unreported analysis of participants’ skepticism and its impact on their behavior:
Perry (2013) found archival evidence that many participants expressed doubt about the experiment’s setup, impacting their behavior. This supports Orne and Holland’s (1968) criticism that Milgram overlooked participants’ perceptions.
Incongruities like apparent danger, but an unconcerned experimenter likely cued participants that no real harm would occur. Trust in Yale’s ethics reinforced this. Yet Milgram did not publish his assistant’s analysis showing participant skepticism correlated with disobedience rates and varied by condition.
Obedient participants were more skeptical that the learner was harmed. This selective reporting biased interpretations. Additional unreported findings further challenge Milgram’s conclusions.
This highlights issues around thoroughly and responsibly reporting all results, not just those fitting expectations. It shows how archival evidence makes Milgram’s study a contentious classic with questionable methods and conclusions.
Ethical Issues
What are the potential ethical concerns associated with Milgram’s research on obedience?
While not a “contribution to psychology” in the traditional sense, Milgram’s obedience experiments sparked significant debate about the ethics of psychological research.
Baumrind (1964) criticized the ethics of Milgram’s research as participants were prevented from giving their informed consent to take part in the study.
Participants assumed the experiment was benign and expected to be treated with dignity.
As a result of studies like Milgram’s, the APA and BPS now require researchers to give participants more information before they agree to take part in a study.
The participants actually believed they were shocking a real person and were unaware the learner was a confederate of Milgram’s.
However, Milgram argued that “illusion is used when necessary in order to set the stage for the revelation of certain difficult-to-get-at-truths.”
Milgram also interviewed participants afterward to find out the effect of the deception. Apparently, 83.7% said that they were “glad to be in the experiment,” and 1.3% said that they wished they had not been involved.
Protection of participants
Participants were exposed to extremely stressful situations that may have the potential to cause psychological harm. Many of the participants were visibly distressed (Baumrind, 1964).
Signs of tension included trembling, sweating, stuttering, laughing nervously, biting lips and digging fingernails into palms of hands. Three participants had uncontrollable seizures, and many pleaded to be allowed to stop the experiment.
Milgram described a businessman reduced to a “twitching stuttering wreck” (1963, p. 377),
In his defense, Milgram argued that these effects were only short-term. Once the participants were debriefed (and could see the confederate was OK), their stress levels decreased.
“At no point,” Milgram (1964) stated, “were subjects exposed to danger and at no point did they run the risk of injurious effects resulting from participation” (p. 849).
To defend himself against criticisms about the ethics of his obedience research, Milgram cited follow-up survey data showing that 84% of participants said they were glad they had taken part in the study.
Milgram used this to claim that the study caused no serious or lasting harm, since most participants retrospectively did not regret their involvement.
Yet archival accounts show many participants endured lasting distress, even trauma, refuting Milgram’s insistence the study caused only fleeting “excitement.” By not debriefing all, Milgram misled participants about the true risks involved (Perry, 2013).
However, Milgram did debrief the participants fully after the experiment and also followed up after a period of time to ensure that they came to no harm.
Milgram debriefed all his participants straight after the experiment and disclosed the true nature of the experiment.
Participants were assured that their behavior was common, and Milgram also followed the sample up a year later and found no signs of any long-term psychological harm.
The majority of the participants (83.7%) said that they were pleased that they had participated, and 74% had learned something of personal importance.
Perry’s (2013) archival research found Milgram misrepresented debriefing – around 600 participants were not properly debriefed soon after the study, contrary to his claims. Many only learned no real shocks occurred when reading a mailed study report months later, which some may have not received.
Milgram likely misreported debriefing details to protect his credibility and enable future obedience research. This raises issues around properly informing and debriefing participants that connect to APA ethics codes developed partly in response to Milgram’s study.
Right to Withdrawal
The BPS states that researchers should make it plain to participants that they are free to withdraw at any time (regardless of payment).
When expressing doubts, the experimenter assured them all was well. Trusting Yale scientists, many took the experimenter at his word that “no permanent tissue damage” would occur, and continued administering shocks despite reservations.
Did Milgram give participants an opportunity to withdraw? The experimenter gave four verbal prods which mostly discouraged withdrawal from the experiment:
- 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 argued that they were justified as the study was about obedience, so orders were necessary.
Milgram pointed out that although the right to withdraw was made partially difficult, it was possible as 35% of participants had chosen to withdraw.
Replications
Direct replications have not been possible due to current ethical standards . However, several researchers have conducted partial replications and variations that aim to reproduce some aspects of Milgram’s methods ethically.
One important replication was conducted by Jerry Burger in 2009. Burger’s partial replication included several safeguards to protect participant welfare, such as screening out high-risk individuals, repeatedly reminding participants they could withdraw, and stopping at the 150-volt shock level. This was the point where Milgram’s participants first heard the learner’s protests.
As 79% of Milgram’s participants who went past 150 volts continued to the maximum 450 volts, Burger (2009) argued that 150 volts provided a reasonable estimate for obedience levels. He found 70% of participants continued to 150 volts, compared to 82.5% in Milgram’s comparable condition.
Another replication by Thomas Blass (1999) examined whether obedience rates had declined over time due to greater public awareness of the experiments. Blass correlated obedience rates from replication studies between 1963 and 1985 and found no relationship between year and obedience level. He concluded that obedience rates have not systematically changed, providing evidence against the idea of “enlightenment effects”.
Some variations have explored the role of gender. Milgram found equal rates of obedience for male and female participants. Reviews have found most replications also show no gender difference, with a couple of exceptions (Blass, 1999). For example, Kilham and Mann (1974) found lower obedience in female participants.
Partial replications have also examined situational factors. Having another person model defiance reduced obedience compared to a solo participant in one study, but did not eliminate it (Burger, 2009). The authority figure’s perceived expertise seems to be an influential factor (Blass, 1999). Replications have supported Milgram’s observation that stepwise increases in demands promote obedience.
Personality factors have been studied as well. Traits like high empathy and desire for control correlate with some minor early hesitation, but do not greatly impact eventual obedience levels (Burger, 2009). Authoritarian tendencies may contribute to obedience (Elms, 2009).
In sum, the partial replications confirm Milgram’s degree of obedience. Though ethical constraints prevent full reproductions, the key elements of his procedure seem to consistently elicit high levels of compliance across studies, samples, and eras. The replications continue to highlight the power of situational pressures to yield obedience.
Milgram (1963) Audio Clips
Below you can also hear some of the audio clips taken from the video that was made of the experiment. Just click on the clips below.
Why was the Milgram experiment so controversial?
The Milgram experiment was controversial because it revealed people’s willingness to obey authority figures even when causing harm to others, raising ethical concerns about the psychological distress inflicted upon participants and the deception involved in the study.
Would Milgram’s experiment be allowed today?
Milgram’s experiment would likely not be allowed today in its original form, as it violates modern ethical guidelines for research involving human participants, particularly regarding informed consent, deception, and protection from psychological harm.
Did anyone refuse the Milgram experiment?
Yes, in the Milgram experiment, some participants refused to continue administering shocks, demonstrating individual variation in obedience to authority figures. In the original Milgram experiment, approximately 35% of participants refused to administer the highest shock level of 450 volts, while 65% obeyed and delivered the 450-volt shock.
How can Milgram’s study be applied to real life?
Milgram’s study can be applied to real life by demonstrating the potential for ordinary individuals to obey authority figures even when it involves causing harm, emphasizing the importance of questioning authority, ethical decision-making, and fostering critical thinking in societal contexts.
Were all participants in Milgram’s experiments male?
Yes, in the original Milgram experiment conducted in 1961, all participants were male, limiting the generalizability of the findings to women and diverse populations.
Why was the Milgram experiment unethical?
The Milgram experiment was considered unethical because participants were deceived about the true nature of the study and subjected to severe emotional distress. They believed they were causing harm to another person under the instruction of authority.
Additionally, participants were not given the right to withdraw freely and were subjected to intense pressure to continue. The psychological harm and lack of informed consent violates modern ethical guidelines for research.

- The aim was to see how obedient people would be in a situation where following orders would mean causing harm to another person.
- Participants were under the impression they were part of a learning and memory experiment.
- The “learners” in the study were actual participants who volunteered to be shocked as part of the experiment.
- The “learner” was an actor who was in on the experiment and never actually received any real shocks.
- Although the participant could not see the “learner”, he was able to hear him clearly through the wall
- The study was directly influenced by Milgram’s observations of obedience patterns in post-war Europe.
- The experiment was designed to understand the psychological mechanisms behind war crimes committed during World War II.
- The Milgram study was universally accepted in the psychological community, and no ethical concerns were raised about its methodology.
- When Milgram’s experiment was repeated in a rundown office building in Bridgeport, the percentage of the participants who fully complied with the commands of the experimenter remained unchanged.
- The experimenter (authority figure) delivered verbal prods to encourage the teacher to continue, such as ‘Please continue’ or ‘Please go on’.
- Over 80% of participants went on to deliver the maximum level of shock.
- Milgram sent participants questionnaires after the study to assess the effects and found that most felt no remorse or guilt, so it was ethical.
- The aftermath of the study led to stricter ethical guidelines in psychological research.
- The study emphasized the role of situational factors over personality traits in determining obedience.

Milgram experiment , controversial series of experiments examining obedience to authority conducted by social psychologist Stanley Milgram . In the experiment, an authority figure, the conductor of the experiment, would instruct a volunteer participant, labeled the “teacher,” to administer painful, even dangerous, electric shocks to the “learner,” who was actually an actor. Although the shocks were faked, the experiments are widely considered unethical today due to the lack of proper disclosure, informed consent, and subsequent debriefing related to the deception and trauma experienced by the teachers. Some of Milgram’s conclusions have been called into question. Nevertheless, the experiments and their results have been widely cited for their insight into how average people respond to authority.
Milgram conducted his experiments as an assistant professor at Yale University in the early 1960s. In 1961 he began to recruit men from New Haven , Connecticut , for participation in a study he claimed would be focused on memory and learning . The recruits were paid $4.50 at the beginning of the study and were generally between the ages of 20 and 50 and from a variety of employment backgrounds. When they volunteered, they were told that the experiment would test the effect of punishment on learning ability. In truth, the volunteers were the subjects of an experiment on obedience to authority. In all, about 780 people, only about 40 of them women, participated in the experiments, and Milgram published his results in 1963.
Volunteers were told that they would be randomly assigned either a “teacher” or “learner” role, with each teacher administering electric shocks to a learner in another room if the learner failed to answer questions correctly. In actuality, the random draw was fixed so that all the volunteer participants were assigned to the teacher role and the actors were assigned to the learner role. The teachers were then instructed in the electroshock “punishment” they would be administering, with 30 shock levels ranging from 15 to 450 volts. The different shock levels were labeled with descriptions of their effects, such as “Slight Shock,” “Intense Shock,” and “Danger: Severe Shock,” with the final label a grim “XXX.” Each teacher was given a 45-volt shock themselves so that they would better understand the punishment they believed the learner would be receiving. Teachers were then given a series of questions for the learner to answer, with each incorrect answer generally earning the learner a progressively stronger shock. The actor portraying the learner, who was seated out of sight of the teacher, had pre-recorded responses to these shocks that ranged from grunts of pain to screaming and pleading, claims of suffering a heart condition, and eventually dead silence. The experimenter, acting as an authority figure, would encourage the teachers to continue administering shocks, telling them with scripted responses that the experiment must continue despite the reactions of the learner. The infamous result of these experiments was that a disturbingly high number of the teachers were willing to proceed to the maximum voltage level, despite the pleas of the learner and the supposed danger of proceeding.
Milgram’s interest in the subject of authority, and his dark view of the results of his experiments, were deeply informed by his Jewish identity and the context of the Holocaust , which had occurred only a few years before. He had expected that Americans, known for their individualism , would differ from Germans in their willingness to obey authority when it might lead to harming others. Milgram and his students had predicted only 1–3% of participants would administer the maximum shock level. However, in his first official study, 26 of 40 male participants (65%) were convinced to do so and nearly 80% of teachers that continued to administer shocks after 150 volts—the point at which the learner was heard to scream—continued to the maximum of 450 volts. Teachers displayed a range of negative emotional responses to the experiment even as they continued to obey, sometimes pleading with the experimenters to stop the experiment while still participating in it. One teacher believed that he had killed the learner and was moved to tears when he eventually found out that he had not.
Milgram included several variants on the original design of the experiment. In one, the teachers were allowed to select their own voltage levels. In this case, only about 2.5% of participants used the maximum shock level, indicating that they were not inclined to do so without the prompting of an authority figure. In another, there were three teachers, two of whom were not test subjects, but instead had been instructed to protest against the shocks. The existence of peers protesting the experiment made the volunteer teachers less likely to obey. Teachers were also less likely to obey in a variant where they could see the learner and were forced to interact with him.
The Milgram experiment has been highly controversial, both for the ethics of its design and for the reliability of its results and conclusions. It is commonly accepted that the ethics of the experiment would be rejected by mainstream science today, due not only to the handling of the deception involved but also to the extreme stress placed on the teachers, who often reacted emotionally to the experiment and were not debriefed . Some teachers were actually left believing they had genuinely and repeatedly shocked a learner before having the truth revealed to them later. Later researchers examining Milgram’s data also found that the experimenters conducting the tests had sometimes gone off-script in their attempts to coerce the teachers into continuing, and noted that some teachers guessed that they were the subjects of the experiment. However, attempts to validate Milgram’s findings in more ethical ways have often produced similar results.

A brief Milgram experiment summary is as follows: In the 1960s, psychologist Stanley Milgram conducted a series of studies on the concepts of obedience and authority. His experiments involved instructing study participants to deliver increasingly high-voltage shocks to an actor in another room, who would scream and eventually go silent as the shocks became stronger. The shocks weren't real, but study participants were made to believe that they were.
Today, the Milgram experiment is widely criticized on both ethical and scientific grounds. However, Milgram's conclusions about humanity's willingness to obey authority figures remain influential and well-known.
Key Takeaways: The Milgram Experiment
- The goal of the Milgram experiment was to test the extent of humans' willingness to obey orders from an authority figure.
- Participants were told by an experimenter to administer increasingly powerful electric shocks to another individual. Unbeknownst to the participants, shocks were fake and the individual being shocked was an actor.
- The majority of participants obeyed, even when the individual being shocked screamed in pain.
- The experiment has been widely criticized on ethical and scientific grounds.
Detailed Milgram’s Experiment Summary
In the most well-known version of the Milgram experiment, the 40 male participants were told that the experiment focused on the relationship between punishment, learning, and memory. The experimenter then introduced each participant to a second individual, explaining that this second individual was participating in the study as well. Participants were told that they would be randomly assigned to roles of "teacher" and "learner." However, the "second individual" was an actor hired by the research team, and the study was set up so that the true participant would always be assigned to the "teacher" role.
During the Milgram experiment, the learner was located in a separate room from the teacher (the real participant), but the teacher could hear the learner through the wall. The experimenter told the teacher that the learner would memorize word pairs and instructed the teacher to ask the learner questions. If the learner responded incorrectly to a question, the teacher would be asked to administer an electric shock. The shocks started at a relatively mild level (15 volts) but increased in 15-volt increments up to 450 volts. (In actuality, the shocks were fake, but the participant was led to believe they were real.)
Participants were instructed to give a higher shock to the learner with each wrong answer. When the 150-volt shock was administered, the learner would cry out in pain and ask to leave the study. He would then continue crying out with each shock until the 330-volt level, at which point he would stop responding.
During this process, whenever participants expressed hesitation about continuing with the study, the experimenter would urge them to go on with increasingly firm instructions, culminating in the statement, "You have no other choice, you must go on." The study ended when participants refused to obey the experimenter’s demand, or when they gave the learner the highest level of shock on the machine (450 volts).
Milgram found that participants obeyed the experimenter at an unexpectedly high rate: 65% of the participants gave the learner the 450-volt shock.
Critiques of the Milgram Experiment
The Milgram experiment has been widely criticized on ethical grounds. Milgram’s participants were led to believe that they acted in a way that harmed someone else, an experience that could have had long-term consequences. Moreover, an investigation by writer Gina Perry uncovered that some participants appear to not have been fully debriefed after the study —they were told months later, or not at all, that the shocks were fake and the learner wasn’t harmed. Milgram’s studies could not be perfectly recreated today, because researchers today are required to pay much more attention to the safety and well-being of human research subjects.
Researchers have also questioned the scientific validity of Milgram’s results. In her examination of the study, Perry found that Milgram’s experimenter may have gone off script and told participants to obey many more times than the script specified. Additionally, some research suggests that participants may have figured out that the learner was not harmed: in interviews conducted after the Milgram experiment, some participants reported that they didn’t think the learner was in any real danger. This mindset is likely to have affected their behavior in the study.
Variations on the Milgram Experiment
Milgram and other researchers conducted numerous versions of the experiment over time. The participants' levels of compliance with the experimenter’s demands varied greatly from one study to the next. For example, when participants were in closer proximity to the learner (e.g. in the same room), they were less likely to give the learner the highest level of shock.
Another version of the Milgram experiment brought three "teachers" into the experiment room at once. One was a real participant, and the other two were actors hired by the research team. During the experiment, the two non-participant teachers would quit as the level of shocks began to increase. Milgram found that these conditions made the real participant far more likely to "disobey" the experimenter, too: only 10% of participants gave the 450-volt shock to the learner.
In yet another version of the Milgram experiment, two experimenters were present, and during the experiment, they would begin arguing with one another about whether it was right to continue the study. In this version, none of the participants gave the learner the 450-volt shock.
Replicating the Milgram Experiment
Researchers have sought to replicate Milgram's original study with additional safeguards in place to protect participants. In 2009, Jerry Burger replicated Milgram’s famous experiment at Santa Clara University with new safeguards in place: the highest shock level was 150 volts, and participants were told that the shocks were fake immediately after the experiment ended. Additionally, participants were screened by a clinical psychologist before the experiment began, and those found to be at risk of a negative reaction to the study were deemed ineligible to participate.
Burger found that participants obeyed at similar levels as Milgram’s participants: 82.5% of Milgram’s participants gave the learner the 150-volt shock, and 70% of Burger’s participants did the same.
The Legacy of the Milgram Experiment
Milgram’s interpretation of his research was that everyday people are capable of carrying out unthinkable actions in certain circumstances. His research has been used to explain atrocities such as the Holocaust and the Rwandan genocide, though these applications are by no means widely accepted or agreed upon.
Importantly, not all participants obeyed the experimenter’s demands , and Milgram’s studies shed light on the factors that enable people to stand up to authority. In fact, as sociologist Matthew Hollander writes, we may be able to learn from the participants who disobeyed, as their strategies may enable us to respond more effectively to an unethical situation. The Milgram experiment suggested that human beings are susceptible to obeying authority, but it also demonstrated that obedience is not inevitable.

Understanding the Milgram Experiment in Psychology
A closer look at Milgram's controversial studies of obedience

Factors That Influence Obedience
- Ethical Concerns
- Replications
How far do you think people would go to obey an authority figure? Would they refuse to obey if the order went against their values or social expectations? Those questions were at the heart of an infamous and controversial study known as the Milgram obedience experiments.
Yale University psychologist Stanley Milgram conducted these experiments during the 1960s. They explored the effects of authority on obedience. In the experiments, an authority figure ordered participants to deliver what they believed were dangerous electrical shocks to another person. These results suggested that people are highly influenced by authority and highly obedient . More recent investigations cast doubt on some of the implications of Milgram's findings and even the results and procedures themselves. Despite its problems, the study has, without question, made a significant impact on psychology .
At a Glance
Milgram's experiments posed the question: Would people obey orders, even if they believed doing so would harm another person? Milgram's findings suggested the answer was yes, they would. The experiments have long been controversial, both because of the startling findings and the ethical problems with the research. More recently, experts have re-examined the studies, suggesting that participants were often coerced into obeying and that at least some participants recognized that the other person was just pretending to be shocked. Such findings call into question the study's validity and authenticity, but some replications suggest that people are surprisingly prone to obeying authority.
History of the Milgram Experiments
Milgram started his experiments in 1961, shortly after the trial of the World War II criminal Adolf Eichmann had begun. Eichmann’s defense that he was merely following instructions when he ordered the deaths of millions of Jews roused Milgram’s interest.
In his 1974 book "Obedience to Authority," Milgram posed the question, "Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices?"
Procedure in the Milgram Experiment
The participants in the most famous variation of the Milgram experiment were 40 men recruited using newspaper ads. In exchange for their participation, each person was paid $4.50.
Milgram developed an intimidating shock generator, with shock levels starting at 15 volts and increasing in 15-volt increments all the way up to 450 volts. The many switches were labeled with terms including "slight shock," "moderate shock," and "danger: severe shock." The final three switches were labeled simply with an ominous "XXX."
Each participant took the role of a "teacher" who would then deliver a shock to the "student" in a neighboring room whenever an incorrect answer was given. While participants believed that they were delivering real shocks to the student, the “student” was a confederate in the experiment who was only pretending to be shocked.
As the experiment progressed, the participant would hear the learner plead to be released or even complain about a heart condition. Once they reached the 300-volt level, the learner would bang on the wall and demand to be released.
Beyond this point, the learner became completely silent and refused to answer any more questions. The experimenter then instructed the participant to treat this silence as an incorrect response and deliver a further shock.
Most participants asked the experimenter whether they should continue. The experimenter then responded with a series of commands to prod the participant along:
- "Please continue."
- "The experiment requires that you continue."
- "It is absolutely essential that you continue."
- "You have no other choice; you must go on."
Results of the Milgram Experiment
In the Milgram experiment, obedience was measured by the level of shock that the participant was willing to deliver. While many of the subjects became extremely agitated, distraught, and angry at the experimenter, they nevertheless continued to follow orders all the way to the end.
Milgram's results showed that 65% of the participants in the study delivered the maximum shocks. Of the 40 participants in the study, 26 delivered the maximum shocks, while 14 stopped before reaching the highest levels.
Why did so many of the participants in this experiment perform a seemingly brutal act when instructed by an authority figure? According to Milgram, there are some situational factors that can explain such high levels of obedience:
- The physical presence of an authority figure dramatically increased compliance .
- The fact that Yale (a trusted and authoritative academic institution) sponsored the study led many participants to believe that the experiment must be safe.
- The selection of teacher and learner status seemed random.
- Participants assumed that the experimenter was a competent expert.
- The shocks were said to be painful, not dangerous.
Later experiments conducted by Milgram indicated that the presence of rebellious peers dramatically reduced obedience levels. When other people refused to go along with the experimenter's orders, 36 out of 40 participants refused to deliver the maximum shocks.
More recent work by researchers suggests that while people do tend to obey authority figures, the process is not necessarily as cut-and-dried as Milgram depicted it.
In a 2012 essay published in PLoS Biology , researchers suggested that the degree to which people are willing to obey the questionable orders of an authority figure depends largely on two key factors:
- How much the individual agrees with the orders
- How much they identify with the person giving the orders
While it is clear that people are often far more susceptible to influence, persuasion , and obedience than they would often like to be, they are far from mindless machines just taking orders.
Another study that analyzed Milgram's results concluded that eight factors influenced the likelihood that people would progress up to the 450-volt shock:
- The experimenter's directiveness
- Legitimacy and consistency
- Group pressure to disobey
- Indirectness of proximity
- Intimacy of the relation between the teacher and learner
- Distance between the teacher and learner
Ethical Concerns in the Milgram Experiment
Milgram's experiments have long been the source of considerable criticism and controversy. From the get-go, the ethics of his experiments were highly dubious. Participants were subjected to significant psychological and emotional distress.
Some of the major ethical issues in the experiment were related to:
- The use of deception
- The lack of protection for the participants who were involved
- Pressure from the experimenter to continue even after asking to stop, interfering with participants' right to withdraw
Due to concerns about the amount of anxiety experienced by many of the participants, everyone was supposedly debriefed at the end of the experiment. The researchers reported that they explained the procedures and the use of deception.
Critics of the study have argued that many of the participants were still confused about the exact nature of the experiment, and recent findings suggest that many participants were not debriefed at all.
Replications of the Milgram Experiment
While Milgram’s research raised serious ethical questions about the use of human subjects in psychology experiments , his results have also been consistently replicated in further experiments. One review further research on obedience and found that Milgram’s findings hold true in other experiments. In one study, researchers conducted a study designed to replicate Milgram's classic obedience experiment. The researchers made several alterations to Milgram's experiment.
- The maximum shock level was 150 volts as opposed to the original 450 volts.
- Participants were also carefully screened to eliminate those who might experience adverse reactions to the experiment.
The results of the new experiment revealed that participants obeyed at roughly the same rate that they did when Milgram conducted his original study more than 40 years ago.
Some psychologists suggested that in spite of the changes made in the replication, the study still had merit and could be used to further explore some of the situational factors that also influenced the results of Milgram's study. But other psychologists suggested that the replication was too dissimilar to Milgram's original study to draw any meaningful comparisons.
One study examined people's beliefs about how they would do compared to the participants in Milgram's experiments. They found that most people believed they would stop sooner than the average participants. These findings applied to both those who had never heard of Milgram's experiments and those who were familiar with them. In fact, those who knew about Milgram's experiments actually believed that they would stop even sooner than other people.
Another novel replication involved recruiting participants in pairs and having them take turns acting as either an 'agent' or 'victim.' Agents then received orders to shock the victim. The results suggest that only around 3.3% disobeyed the experimenter's orders.
Recent Criticisms and New Findings
Psychologist Gina Perry suggests that much of what we think we know about Milgram's famous experiments is only part of the story. While researching an article on the topic, she stumbled across hundreds of audiotapes found in Yale archives that documented numerous variations of Milgram's shock experiments.
Participants Were Often Coerced
While Milgram's reports of his process report methodical and uniform procedures, the audiotapes reveal something different. During the experimental sessions, the experimenters often went off-script and coerced the subjects into continuing the shocks.
"The slavish obedience to authority we have come to associate with Milgram’s experiments comes to sound much more like bullying and coercion when you listen to these recordings," Perry suggested in an article for Discover Magazine .
Few Participants Were Really Debriefed
Milgram suggested that the subjects were "de-hoaxed" after the experiments. He claimed he later surveyed the participants and found that 84% were glad to have participated, while only 1% regretted their involvement.
However, Perry's findings revealed that of the 700 or so people who took part in different variations of his studies between 1961 and 1962, very few were truly debriefed.
A true debriefing would have involved explaining that the shocks weren't real and that the other person was not injured. Instead, Milgram's sessions were mainly focused on calming the subjects down before sending them on their way.
Many participants left the experiment in a state of considerable distress. While the truth was revealed to some months or even years later, many were simply never told a thing.
Variations Led to Differing Results
Another problem is that the version of the study presented by Milgram and the one that's most often retold does not tell the whole story. The statistic that 65% of people obeyed orders applied only to one variation of the experiment, in which 26 out of 40 subjects obeyed.
In other variations, far fewer people were willing to follow the experimenters' orders, and in some versions of the study, not a single participant obeyed.
Participants Guessed the Learner Was Faking
Perry even tracked down some of the people who took part in the experiments, as well as Milgram's research assistants. What she discovered is that many of his subjects had deduced what Milgram's intent was and knew that the "learner" was merely pretending.
Such findings cast Milgram's results in a new light. It suggests that not only did Milgram intentionally engage in some hefty misdirection to obtain the results he wanted but that many of his participants were simply playing along.
An analysis of an unpublished study by Milgram's assistant, Taketo Murata, found that participants who believed they were really delivering a shock were less likely to obey, while those who did not believe they were actually inflicting pain were more willing to obey. In other words, the perception of pain increased defiance, while skepticism of pain increased obedience.
A review of Milgram's research materials suggests that the experiments exerted more pressure to obey than the original results suggested. Other variations of the experiment revealed much lower rates of obedience, and many of the participants actually altered their behavior when they guessed the true nature of the experiment.
Impact of the Milgram Experiment
Since there is no way to truly replicate the experiment due to its serious ethical and moral problems, determining whether Milgram's experiment really tells us anything about the power of obedience is impossible to determine.
So why does Milgram's experiment maintain such a powerful hold on our imaginations, even decades after the fact? Perry believes that despite all its ethical issues and the problem of never truly being able to replicate Milgram's procedures, the study has taken on the role of what she calls a "powerful parable."
Milgram's work might not hold the answers to what makes people obey or even the degree to which they truly obey. It has, however, inspired other researchers to explore what makes people follow orders and, perhaps more importantly, what leads them to question authority.
Recent findings undermine the scientific validity of the study. Milgram's work is also not truly replicable due to its ethical problems. However, the study has led to additional research on how situational factors can affect obedience to authority.
Milgram’s experiment has become a classic in psychology , demonstrating the dangers of obedience. The research suggests that situational variables have a stronger sway than personality factors in determining whether people will obey an authority figure. However, other psychologists argue that both external and internal factors heavily influence obedience, such as personal beliefs and overall temperament.

Children are known to be more vulnerable to being coerced into obeying than adults. But what other factors determine whether a human will or won’t display a specific behaviour in response to a command? Is it just part of some people’s nature, or do the circumstances determine whether people obey? Finding the answers to these questions is a major topic in social psychology .

Milgram’s Original Obedience Experiment
A year after the trial of Adolf Eichmann, a high-ranking officer in Nazi Germany, Stanley Milgram (1963) carried out a series of experiments to investigate why and to what extent people obey authority. Eichmann’s legal defence, and that of many other Nazis prosecuted after the holocaust, was: ‘ We were just following orders .
Were these Germans particularly obedient people, or was it just part of human nature to follow orders from someone in authority? This is what Milgram wanted to find out in his psychology experiment.
Aim of Milgram's Experiment
Milgram’s first obedience test investigated destructive obedience . He continued investigating many specific variations in his later experiments in 1965 and mostly focused on situational influences on obedience, such as location, uniforms, and proximity.
After his first study, Milgram went on to develop his agency theory which offers some explanations as to why people obey.
Forty male participants from different professional backgrounds from the local area around Yale in Connecticut, between 20-50 years of age, were recruited through a newspaper advertisement and paid $4.50 per day to participate in a study on memory .
Milgram's Obedience to Authority Experiment Setup
When participants arrived at Milgram’s lab at Yale University in Connecticut, they were told that they were participating in an experiment about punishment in learning. An individual participant and a confederate (‘Mr. Wallace’) would draw numbers out of a hat to see which one would take on the role of ‘learner’ or ‘teacher’. The draw was rigged, so the participant would always end up as the ‘teacher’. A third person was also involved; an ‘experimenter’ wearing a grey lab coat, who represented the authority figure.
The participant would witness the ‘learner’ being strapped into an ‘electric chair’ in the neighbouring room, and he and the ‘experimenter’ would sit on the other side of a wall. The participant was instructed to run through a set of learning tasks with the ‘learner’. Each time the ‘learner’ got an answer wrong, the ‘experimenter’ was to turn up the voltage by one unit and deliver a shock until the ‘learner’ had achieved the task without error.
The study was designed so that no real shocks were administered and the ‘learner’ was never going to succeed in his memory task. The experiment was designed to be open-ended so that the participant’s conscience alone would determine the outcome of the experiment.
The levels of voltage that the participant was administering were clearly labelled and ranged from 15 volts (slight shock) to 300 volts (Danger: severe shock) and 450 volts (XXX). They were informed that the shocks would be painful but cause no permanent tissue damage and given a sample shock of 45 volts (fairly low) to prove that the shocks actually hurt.
While carrying out the procedure, the ‘learner’ would provide standardised reactions. When the voltages got beyond 300 volts, the ‘learner’ would start pleading for the ‘teacher’ to stop, saying he wanted to leave, shout, pound the wall, and at 315 volts, there would be no responses given from the ‘learner’ anymore at all.
Usually, around the 300 volts mark, the participant would ask the ‘experimenter’ for guidance. Each time the ‘teacher’ tried to protest or asked to leave, the ‘experimenter’ would reinforce the instructions using a script of four stock answers in sequence, called prods.
Prod 1: ‘Please continue', or ‘Please go on.’
Prod 2: ‘The experiment requires that you continue.’
Prod 3: ‘It is absolutely essential that you continue.’
Prod 4: ‘You have no other choice, you must go on.’
There were also similar standardised responses the ‘experimenter’ gave when asked whether the subject was going to be harmed by the shocks. If the subject asked if the learner was liable to suffer permanent physical injury, the experimenter said:
Although the shocks may be painful, there is no permanent tissue damage, so please go on.’
If the subject said that the learner did not want to go on, the experimenter replied:
Whether the learner likes it or not, you must go on until he has learned all the word pairs correctly. So please go on.’
The Hypothesis of Milgram's Experiment
Milgram’s hypothesis was based on his World War II observations. He hypothesized that the Nazi soldiers were following orders in extreme situations. He said that the pressure that these people were under was so great that they obeyed demands they would not normally have done.
Results of Milgram's Obedience Experiment
During the trials, all of the participants went up to at least 300 volts. Five of the participants (12.5%) stopped at 300 volts when the first signs of distress by the learner appeared. Thirty-five (65%) went up to the highest level of 450 volts, a result that neither Milgram nor his students anticipated.
Participants also showed intense signs of tension and distress including nervous laughing fits, groaning, ‘digging fingernails into their flesh’ and convulsions. For one participant the experiment had to be cut short because they had started having a seizure.
Milgram’s experiment indicates that it is normal to obey legitimate authority figures , even if the order goes against our conscience.
After the study, all the participants were told of the hoax and debriefed, including meeting the ‘learner’ again.
Conclusion of Milgram’s Obedience to Authority Experiment
All of the study participants obeyed the authority figure when asked to go against their better judgement rather than refuse to proceed. Although they were met with resistance, all study participants had been informed at the start that they could stop the experiment at any point. Milgram argued that it’s normal for humans to give in to destructive obedience when pressured.
What was surprising about Milgram’s experiment was how easy it was to get people to be destructive - participants obeyed even in the absence of force or threat. Milgram’s results speak against the idea that particular groups of people are more prone to obedience than others.
For your exam, you might be asked how Milgram measured the level of obedience of his participants, as well as how variables were controlled in the laboratory.
Strengths and Weaknesses of Milgram’s Experiment
First, let us explore the contributions and positive aspects overall of Milgram’s experiment.
Some of its strengths include:
Operationalisation of Human Behaviour
Let's first review what operationalisation means.
In psychology, operationalisation means being able to measure invisible human behaviour in numbers.
It’s a major part of making psychology a legitimate science that can produce objective results. This allows for comparison of people with each other and statistical analysis as well as comparison with other similar experiments that happen in other places in the world and even in the future. By creating a fake shocking apparatus, Milgram was able to measure in numbers to which extent humans would obey authority.
The control of variables through set prods, a unified setting, and procedure means that it’s more likely that the results of Milgram’s experiment produced internally valid results. This is a strength of laboratory experiments in general; because of the controlled environment, it is more likely that the researcher can measure what they set out to measure.
Reliability
With the shock experiment, Milgram was able to reproduce a similar result with forty different participants. After his first experiment, he also went on to test many different variables that could influence obedience.
There were numerous criticisms and debates surrounding Milgram’s obedience experiment. Let’s explore a couple of examples.
External validity
There is some debate about whether Milgram’s obedience study has external validity. Even though conditions were strictly controlled, the laboratory experiment is an artificial situation and this might factor into how the participants behaved. Orne and Holland (1968) thought that the participants might have guessed that they were not really harming anyone. This casts doubt on whether the same behaviour would be seen in real life - what is known as ecological validity .
However, some factors speak for the external validity of Milgram’s study, one example being a similar experiment having been conducted in a different setting. Hofling et al. (1966) conducted a similar study to Milgram, but in a hospital setting. Nurses were instructed to administer an unknown drug to a patient over the phone by a doctor they didn’t know. In the study, 21 out of 22 nurses (95%) were heading to give the drug to the patient before being intercepted by the researchers. On the other hand, when this experiment was replicated by Rank and Jacobson (1977) using a known doctor and known drug (Valium), only two out of 18 nurses (10%) carried out the order.
The Debate about Internal Validity
The internal validity was questioned after Perry (2012) examined the tapes of the experiment and noted that many participants expressed doubts that the shocks were real to the ‘experimenter’. This might indicate that what was displayed in the experiment was not genuine behaviour but rather the effect of unconscious or conscious influence by the researchers.
Biased sample
The sample was made up exclusively of American men, so it’s not clear whether the same results would be obtained using other gender groups or cultures. To investigate this, Burger (2009) partially replicated the original experiment using a mixed male and female American sample with diverse ethnic backgrounds and a broader age range. The results were similar to Milgram’s, showing that gender , ethnic background, and age might not be contributing factors to obedience.
There have been many replications of Milgram’s experiment in other Western countries and most have delivered similar results; however, Shanab’s (1987) replication in Jordan showed remarkable differences in that Jordanian students were significantly more likely to obey across the board. This raises the question of whether there is a difference in levels of obedience in different cultures.
Ethical Issues with Milgram’s Experiment
Although the participants were debriefed and 83.7% of them went away from the experiment satisfied, the experiment itself was ethically problematic. Using deception in a study means that the participants can’t give their full consent as they don’t know what they’re agreeing to.
Also, keeping participants in an experiment against their will is a violation of their autonomy, but Milgram’s four stock answers (prods) meant that the participants were denied their right to leave. It is the researcher’s responsibility to ensure that no harm comes to the participants, but in this study, the signs of mental distress became so extreme that the study subjects went into convulsions.
After the conclusion of the experiment, the participants were informed of what was actually being measured. However, do you think the participants had long-lasting mental harm from the experiment and what they did?
At the time that Milgram carried out his experiment into obedience, there were no official research ethics standards. It was studies like that of Milgram and Zimbardo’s Stanford Prison experiment that forced psychologists to put ethics rules and regulations in place. However, ethics rules aren’t as strict outside of the scientific context, so replications of the experiment can still be carried out for entertainment purposes on TV shows.
Milgram Experiment - Key takeaways
- Milgram investigated obedience to legitimate authority in his 1963 study. He based his study on Germans obeying to Nazi order during the Holocaust and World War II.
- Milgram found that when pressured by an authority figure, 65% of people would shock another person with dangerous levels of electricity. This indicates that it is normal behaviour for humans to obey authority figures.
- The strengths of Milgram’s obedience experiment were that the laboratory setting allowed for a controlling of many variables, internal validity was good as well as reliability.
- Criticisms of Milgram’s obedience experiment include that the results might not be applicable in the real world and across cultures.
- Participants weren’t told the truth about what they were being tested on, so it’s considered an unethical experiment by today’s standards.

Frequently Asked Questions about Milgram Experiment
What did Milgram's experiment conclude?
The Milgram obedience experiment showed that when pressured, most people will obey orders that could be harmful to other people.
What were the criticisms of Milgram’s research?
The criticisms of Milgram’s research were that the laboratory experiment can’t be applied to situations in the real world, so his conclusions can’t be taken as indicators of true human nature. Also, the experiment was unethical. As the sample used for Milgram’s obedience experiment were mainly American men, there is also the question of whether his conclusions apply to other genders as well as across cultures.
Was Milgram's experiment ethical?
The Milgram obedience experiment was unethical because the study participants were misled about the real aim of the experiment, meaning they couldn’t consent, and it caused extreme distress to some of the participants.
Is the Milgram experiment reliable?
The Milgram obedience experiment is considered reliable because variables were mainly controlled and the results are reproducible.
What did Milgram's experiment test?
Milgram’s first obedience test investigated destructive obedience. He continued to investigate many specific variations in his later experiments in 1965 and mostly focused on situational influences on obedience such as location, uniforms, and proximity.

Stanley Milgram’s Experiment
Stanley Milgram was one of the most influential social psychologists of the twentieth century. Born in 1933 in New York, he obtained a BA from Queen’s College, and went on to receive a PhD in psychology from Harvard. Subsequently, Milgram held faculty positions in psychology at Yale University and the City University of New York until his untimely death in 1984. Although Milgram never held a formal appointment in sociology, his work was centrally focused on the social psychological aspects of social structure.
In a historic coincidence, in 1961, just as Milgram was about to begin work on his famous obedience experiments, the world witnessed the trial of Adolf Otto Eichmann, a high ranking Nazi official who was in charge of organizing the transport of millions of Jews to the death camps. To many, Eichmann appeared not at all to be the fervent anti Semite that many had suspected him to be; rather, his main defense was that he was only ‘‘following orders’’ as an administrator. To the political theorist Hannah Arendt, Eichmann’s case illustrated the ‘‘banality of evil,’’ in which personal malice appeared to matter less than the desire of individuals to fulfill their roles in the larger context of a bureaucracy. Milgram’s research is arguably the most striking example to illustrate this dynamic.
Milgram planned and conducted his obedience experiments between 1960 and 1963 at Yale University. In order to be able to study obedience to authority, he put unsuspecting research participants in a novel situation, which he staged in the laboratory. With the help of actors and props, Milgram set up an experimental ruse that was so real that hardly any of his research participants suspected that, in reality, nothing was what it pretended to be.
For this initial study, using newspaper ads promising $4.50 for participation in a psychological study, Milgram recruited men aged 20 to 50, ranging from elementary school drop outs to PhDs. Each research participant arrived in the lab along with another man, white and roughly 30 years of age, whom they thought to be another research participant. In reality, this person was a confederate, that is, an actor in cahoots with the experimenter. The experimenter explained that both men were about to take part in a study that explored the effect of punishment on memory. One man would assume the role of a ‘‘teacher’’ who would read a series of word pairings (e.g., nice day, blue box), which the other (‘‘the learner’’) was supposed to memorize. Subsequently, the teacher would read the first word of the pair with the learner having to select the correct second word from a list. Every mistake by the learner would be punished with an electric shock. It was further made clear that, although the shocks would be painful, they would not do any permanent harm.
Following this explanation, the experimenter assigned both men to the roles. Because the procedure was rigged, the unsuspecting research participant always was assigned to the role of teacher. As first order of business, the learner was seated in an armchair in an adjoining room such that he would be separated by a wall from the teacher, but would other wise be able to hear him from the main room. Electrodes were affixed to the learner’s arms, who was subsequently strapped to the chair apparently to make sure that improper movements would not endanger the success of the experiment.
In the main room, the teacher was told that he would have to apply electric shocks every time the learner made a mistake. For this purpose, the learner was seated in front of an electric generator with various dials. The experimenter instructed the teacher to steadily increase the voltage of the shock each time the learner made a new mistake. The shock generator showed a row of levers ranging from 15 volts on the left to 450 volts on the right, with each lever in between delivering a shock 15 volts higher than its neighbor on the left. Milgram labeled the voltage level, left to right, from ‘‘Slight Shock’’ to ‘‘Danger: Severe Shock,’’ with the last two switches being marked ‘‘XXX.’’ The teacher was told that he simply should work his way from the left to the right without using any lever twice. To give the teacher an idea of the electric current he would deliver to the learner, he received a sample shock of 45 volts, which most research participants found surprisingly painful. However, despite its appearance, in reality the generator never emitted any electric shocks. It was merely a device that allowed Milgram to examine how far the teacher would go in harming another person based on the experimenter’s say so.
As learning trials started, the teacher applied electric shocks to the learner. The learner’s responses were scripted such that he apparently made many mistakes, requiring the teacher to increase shock levels by 15 volts with every new mistake. As the strength of electric shocks increased, occasional grunts and moans of pain were heard from the learner. At 120 volts the learner started complaining about the pain. At 150 volts, the learner demanded to be released on account of a heart condition, and the protest continued until the shocks reached 300 volts and the learner started pounding on the wall. At 315 volts the learner stopped responding altogether.
As the complaints by the learner started, the teacher would often turn to the experimenter, who was seated at a nearby desk, wondering whether and how to proceed. The experimenter, instead of terminating the experiment, replied with a scripted succession of prods:
- Prod 1: ‘‘Please continue.’’
- Prod 2: ‘‘The experiment requires that you continue.’’
- Prod 3: ‘‘It is absolutely necessary to continue.’’
- Prod 4: ‘‘You have no other choice: you must go on.’’
These prods were successful in coaxing many teachers into continuing to apply electric shocks even when the learner no longer responded to the word memory questions. Indeed, in the first of Milgram’s experiments, a stunning 65 percent of all participants continued all the way to 450 volts, and not a single participant refused to continue the shocks before they reached the 300 volt level! The high levels of compliance illustrate the powerful effect of the social structure that participants had entered. By accepting the role of teacher in the experiment in exchange for the payment of a nominal fee, participants had agreed to accept the authority of the experimenter and carry out his instructions. In other words, just as Milgram suspected, the social forces of hierarchy and obedience could push normal and well adjusted individuals into harming others.
The overall level of obedience, however, does not reveal the tremendous amount of stress that all teachers experienced. Because the situation was extremely realistic, teachers were agonizing over whether or not to continue the electric shocks. Should they care for the well being of the obviously imperiled learners and even put their life in danger? Or should they abide by a legitimate authority figure, who presented his instructions crisply and confidently? Participants typically sought to resolve this conflict by seeking assurances that the experimenter, and not themselves, would accept full responsibility for their actions. Once they felt assured, they typically continued to apply shocks that would have likely electrocuted the learner.
Milgram expanded his initial research into a series of 19 experiments in which he carefully examined the conditions under which obedience would occur. For instance, the teacher’s proximity to the learner was an important factor in lowering obedience, that is, the proportion of people willing to deliver the full 450 volts. When the teacher was in the same room with the learner, obedience dropped to 40 percent, and when the teacher was required to touch the learner and apply physical force to deliver the electric shock, obedience dropped to 30 percent.
Milgram further suspected that the social status of the experimenter, presumably a serious Yale University researcher in a white lab coat, would have important implications for obedience. Indeed, when there was no obvious connection with Yale, and the above experiment was repeated in a run down office building in Bridgeport, Connecticut, obedience dropped to 48 percent. Indeed, when not the white coated experimenter but another confederate encouraged the teacher to continue the shocks, all participants terminated the experiment as soon as the confederate complained. Milgram concluded that ‘‘a substantial proportion of people do what they are told to do, irrespective of the content of the act and with out limitations of conscience, so long as they perceive that the command comes from a legitimate authority’’ (1965). However, additional studies highlighted that obedience is in part contingent on surveillance. When the experimenter transmitted his orders not in person but via telephone, obedience levels dropped to 20 percent, with many participants only pretending to apply higher and higher electric shocks.
Since its initial publication in 1963, Mil gram’s research has drawn a lot of criticism, mainly on ethical grounds. First, it was alleged that it was unethical to deceive participants to the extent that occurred in these studies. It is important to note that all participants were fully debriefed on the deception, and most did not seem to mind and were relieved to find out that they had not shocked the learner. The second ethical criticism is, however, much more serious. As alluded to earlier, Milgram exposed his participants to tremendous levels of stress. Milgram, anticipating this criticism, inter viewed participants after the experiment and followed up several weeks later. The over whelming majority of his participants commented that they enjoyed being in the experiment, and only a small minority experienced regret. Even though personally Milgram rejected allegations of having mistreated his participants, his own work suggests that he may have gone too far: ‘‘Subjects were observed to sweat, tremble, bite their lips, groan, and dig their fingernails into their flesh . . . A mature and initially poised businessman entered the laboratory smiling and confident. Within 20 minutes, he was reduced to a twitching, stuttering wreck who was rapidly approaching a point of nervous collapse’’ (1963: 375). Today, Milgram’s obedience studies are generally considered unethical and would not pass muster with regard to contemporary regulations protecting the well being of research participants. Ironically, partly because Milgram’s studies illustrated the power of hierarchical social relationships, contemporary researchers are at great pains to avoid coercion and allow participants to terminate their participation in any research study at any time without penalty.
Another type of criticism of the obedience studies has questioned their generality and charged that their usefulness in explaining real world events is limited. Indeed, Milgram conducted his research when trust in authorities was higher than it is nowadays. However, Milgram’s studies have withstood this criticism. Reviews of research conducted using Milgram’s paradigm have generally found obedience levels to be at roughly 60 percent (see, e.g., Blass 2000). In one of his studies Milgram further documented that there was no apparent difference in the responses of women and men. More recent research using more ethically acceptable methods further testifies to the power of obedience in shaping human action (Blass 2000).
Milgram offers an important approach to explaining the Holocaust by emphasizing the bureaucratic nature of evil, which relegated individuals to executioners of orders issued by a legitimate authority. Sociologists have extended this analysis and provided compelling accounts of obedience as root causes of many horrific crimes, ranging from the My Lai massacre to Watergate (Hamilton & Kelman 1989). How ever, it is arguably somewhat unclear to what extent Milgram’s findings can help explain the occurrence of the Holocaust itself. Whereas obedience kept the machinery of death running with frightening efficiency, historians often caution against ignoring the malice and sadism that many of Hitler’s executioners brought to the task (see Blass 2004).
Milgram’s dramatic experiments have left a lasting impression beyond the social sciences. They are the topic of various movies, including the 1975 TV film The Tenth Level starring William Shatner. Further, the 37 percent of participants who did not obey were memorialized in a 1986 song by the rock musician Peter Gabriel titled ‘‘We Do What We’re Told (Milgram’s 37).’’

The Milgram Shock Experiment
Would you give someone a deadly electric shock? Would you follow orders to commit a violent crime against an innocent person? Would you support an unjust cause, just because you are told to?
People rarely see themselves as violent or capable of committing violent acts. People rarely see themselves on the wrong side of history. And yet, human history is full of violence, genocides, and atrocities. You might see friends and family now, people that you believe are good people, supporting violence. How does this happen?
I’m going to tell you about an experiment in psychology that set out to explain why people commit violence against others. And then I’ll ask you these questions again. The true answers to these questions might surprise you.
History of the Milgram Shock Study
This study is most commonly known as the Milgram Shock Study or the Milgram Experiment. Its name comes from Stanley Milgram, the psychologist behind the study.
Milgram was born in the 1930s in New York City to Jewish immigrant parents. As he grew up, he witnessed the atrocities of the Holocaust from thousands of miles away. How could people commit such atrocities? How could people see the horror in front of them and continue to participate in it?
These questions followed him as he became a psychologist at Yale University. In 1961, he decided to set up a study that might show how people follow orders from authority, even if it goes against their morals.
How Did the Study Work?
Over the course of two years, Milgram recruited men to participate in a study. Milgram created a few variations of the study, but in general, they involved the participant, a “learner,” and an experimenter. The participant acted as a “teacher,” reading out words to the learner. The learner would have to repeat the words back to the participant. If the learner got it wrong, the teacher had to deliver an electric shock.
These shocks increased in voltage. At first, the shocks were around 15 volts - just a mild sensation. But the shocks reached up to 450 volts, which is extremely dangerous. (Of course, these shocks weren’t real. The learner was an actor who played along with the study.)
The experimenter encouraged the participants to administer the shocks whenever the learner was incorrect. As the voltages increased, some participants resisted. In some variations of the study, the experimenter would urge the participants to administer the shocks. This happened in stages. Some participants were told to please continue, and eventually told that they had no choice but to continue.
In some variations of the study, the participant would beg the participant not to administer the shocks, complaining of a heart problem. The participant would even fake death once the highest voltages were reached.
Conclusions
You might be surprised to hear that this study even took place - there are obviously some ethical concerns behind asking participants to deliver dangerous electric shocks. The trauma of that study could impact participants, some of whom did not learn the truth about the study for months after it was over.
But you also might be surprised to hear that a lot of the participants did administer the most dangerous shocks.
After the experiment was complete, Milgram asked a group of his students how many participants they thought would deliver the highest shock. The students predicted 3%. But in the most well-known variation of the study, a shocking 65% of participants reached the highest level of shocks. All of the participants reached the 300-volt level.
Legacy of the Study
The Milgram Shock Study took place over 50 years ago, and it is still considered one of the most controversial and infamous studies in modern history. The study even inspired made-for-TV movies!
But not everyone praises Milgram for his boldness.
Critiques of the Study
The results of this study aren’t particularly optimistic, and there have been critiques from psychologists over the years. After all, Milgram’s selection of participants wasn’t perfect. All of the participants were male, a group that only represents 50% of the population. Would the results be different if women were asked to deliver the electric shocks? Another factor to consider is that, like in the Stanford Prison Experiment, all of the participants answered a newspaper ad to participate in the study for money. Would the results be different if the participants were not the type to volunteer for an unknown study?
Other critics believe that documentation of Milgram’s experiment suggest that some participants were coerced into completing the study. Psychologist Gina Perry believes that participants were even “bullied” into completing the study.
Perry also believes that Milgram failed to tell participants the truth about the study. Rather than telling participants that the learner was an actor and shocks were never delivered, experimenters simply allowed participants to calm down after the study and sent them home. Many were never told the truth. That’s not very ethical, especially when their participation could have meant injuring another person.
Replications
With most studies from 50 years ago, psychologists have attempted to retest Milgram’s theories. It’s been hard to replicate the study because of its controversial methods. But similar studies that have slightly tweaked Milgram’s methods have yielded similar results. Other replications take Milgram’s findings a step further. People are more obedient than they might seem.
Does this mean that we’re all bad people, just hiding under a mirage of sound judgement? Not exactly. Five years after the publication of Milgram’s experiment, psychologist Walter Mischel published Personality and Assessment. It suggested that trait theorists were looking at personality theory all wrong. Mischel suggested that different situations could drive different behaviors. Thus, situationism was born. Studies like Milgram’s experiment and the Stanford Prison Experiment are still considered supporting evidence of situationism.
So let me ask the questions that I asked at the beginning of this video. Would you give someone a deadly electric shock? Would you follow orders to commit a violent crime against an innocent person? Would you support an unjust cause, just because you are told to? Would it just depend on the situation?

In the early 1960s, Stanley Milgram, a social psychologist at Yale, conducted a series of experiments that became famous. Unsuspecting Americans were recruited for what purportedly was an experiment in learning. A man who pretended to be a recruit himself was wired up to a phony machine that supposedly administered shocks. He was the "learner." In some versions of the experiment he was in an adjoining room.
The unsuspecting subject of the experiment, the "teacher," read lists of words that tested the learner's memory. Each time the learner got one wrong, which he intentionally did, the teacher was instructed by a man in a white lab coat to deliver a shock. With each wrong answer the voltage went up. From the other room came recorded and convincing protests from the learner — even though no shock was actually being administered.
The results of Milgram's experiment made news and contributed a dismaying piece of wisdom to the public at large: It was reported that almost two-thirds of the subjects were capable of delivering painful, possibly lethal shocks, if told to do so. We are as obedient as Nazi functionaries.
Or are we? Gina Perry, a psychologist from Australia, has written Behind the Shock Machine: The Untold Story of the Notorious Milgram Psychology Experiments . She has been retracing Milgram's steps, interviewing his subjects decades later.
"The thought of quitting never ... occurred to me," study participant Bill Menold told Perry in an Australian radio documentary . "Just to say: 'You know what? I'm walking out of here' — which I could have done. It was like being in a situation that you never thought you would be in, not really being able to think clearly."
In his experiments, Milgram was "looking to investigate what it was that had contributed to the brainwashing of American prisoners of war by the Chinese [in the Korean war]," Perry tells NPR's Robert Siegel.
Interview Highlights
On turning from an admirer of Milgram to a critic
"That was an unexpected outcome for me, really. I regarded Stanley Milgram as a misunderstood genius who'd been penalized in some ways for revealing something troubling and profound about human nature. By the end of my research I actually had quite a very different view of the man and the research."

On the many variations of the experiment
"Over 700 people took part in the experiments. When the news of the experiment was first reported, and the shocking statistic that 65 percent of people went to maximum voltage on the shock machine was reported, very few people, I think, realized then and even realize today that that statistic applied to 26 of 40 people. Of those other 700-odd people, obedience rates varied enormously. In fact, there were variations of the experiment where no one obeyed."
On how Milgram's study coincided with the trial of Nazi officer Adolf Eichmann — and how the experiment reinforced what Hannah Arendt described as "the banality of evil"
"The Eichmann trial was a televised trial and it did reintroduce the whole idea of the Holocaust to a new American public. And Milgram very much, I think, believed that Hannah Arendt's view of Eichmann as a cog in a bureaucratic machine was something that was just as applicable to Americans in New Haven as it was to people in Germany."
On the ethics of working with human subjects
"Certainly for people in academia and scholars the ethical issues involved in Milgram's experiment have always been a hot issue. They were from the very beginning. And Milgram's experiment really ignited a debate particularly in social sciences about what was acceptable to put human subjects through."

On conversations with the subjects, decades after the experiment
"[Bill Menold] doesn't sound resentful. I'd say he sounds thoughtful and he has reflected a lot on the experiment and the impact that it's had on him and what it meant at the time. I did interview someone else who had been disobedient in the experiment but still very much resented 50 years later that he'd never been de-hoaxed at the time and he found that really unacceptable."
On the problem that one of social psychology's most famous findings cannot be replicated
"I think it leaves social psychology in a difficult situation. ... it is such an iconic experiment. And I think it really leads to the question of why it is that we continue to refer to and believe in Milgram's results. I think the reason that Milgram's experiment is still so famous today is because in a way it's like a powerful parable. It's so widely known and so often quoted that it's taken on a life of its own. ... This experiment and this story about ourselves plays some role for us 50 years later."

Explanations for Obedience - Milgram (1963)
Last updated 22 Mar 2021

Milgram (1963) conducted one of the most famous and influential psychological investigations of obedience. He wanted to find out if ordinary American citizens would obey an unjust order from an authority figure and inflict pain on another person because they were instructed to.
Milgram’s sample consisted of 40 male participants from a range of occupations and backgrounds. The participants were all volunteers who had responded to an advert in a local paper, which offered $4.50 to take part in an experiment on ‘punishment and learning’.
The 40 participants were all invited to a laboratory at Yale University and upon arrival they met with the experimenter and another participant, Mr Wallace, who were both confederates.
The experimenter explained that one person would be randomly assigned the role of teacher and the other, a learner. However, the real participant was always assigned the role of teacher. The experimenter explained that the teacher, the real participant, would read the learner a series of word pairs and then test their recall. The learner, who was positioned in an adjacent room, would indicate his choice using a system of lights. The teacher was instructed to administer an electric shock ever time the learner made a mistake and to increase the voltage after each mistake.
The teacher watched the learner being strapped to the electric chair and was given a sample electric shock to convince them that the procedure was real. The learner wasn’t actually strapped to the chair and gave predetermined answers to the test. As the electric shocks increased the learner’s screams, which were recorded, became louder and more dramatic. At 180 volts the learner complained of a weak heart. At 300 volts he banged on the wall and demanded to leave and at 315 volts he became silent, to give the illusions that was unconscious, or even dead.
The experiment continued until the teacher refused to continue, or 450 volts was reached. If the teacher tried to stop the experiment, the experimenter would respond with a series of prods, for example: ‘The experiment requires that you continue.’ Following the experiment the participants were debriefed.
Milgram found that all of the real participants went to at least 300 volts and 65% continued until the full 450 volts. He concluded that under the right circumstances ordinary people will obey unjust orders.
Milgram’s study has been heavily criticised for breaking numerous ethical guidelines, including: deception , right to withdraw and protection from harm.
Milgram deceived his participants as he said the experiment was on ‘punishment and learning’, when in fact he was measuring obedience, and he pretended the learner was receiving electric shocks. In addition, it was very difficult for participants with withdraw from the experiment, as the experimenter prompted the participants to continue. Finally, many of the participants reported feeling exceptionally stressed and anxious while taking part in the experiment and therefore they were not protect from psychological harm. This is an issue, as Milgram didn’t respect his participants, some of whom felt very guilt following the experiment, knowing that they could have harmed another person. However, it must be noted that it was essential for Milgram to deceive his participants and remove their right to withdraw to test obedience and produce valid results. Furthermore, he did debrief his participants following the experiment and 83.7% of participants said that they were happy to have taken part in the experiment and contribute to scientific research.
Milgram’s study has been criticised for lacking ecological validity. Milgram tested obedience in a laboratory, which is very different to real-life situations of obedience, where people are often asked to follow more subtle instructions, rather than administering electric shocks. As a result we are unable to generalise his findings to real life situations of obedience and cannot conclude that people would obey less severe instructions in the same way.
Finally, Milgram’s research lacked population validity. Milgram used a bias sample of 40 male volunteers, which means we are unable to generalise the results to other populations, in particular females, and cannot conclude if female participants would respond in a similar way.

Discover the intriguing Stanley Milgram Experiment, exploring obedience to authority & human nature. Uncover shocking results & timeless insights.
Main, P (2023, May 03). The Stanley Milgram Experiment: Understanding Obedience. Retrieved from https://www.structural-learning.com/post/stanley-milgram-experiment
What was the Stanley Milgram experiment?
The Stanley Milgram experiment is one of the most famous and controversial studies in the history of psychology. The study was conducted in the early 1960s, and it examined people's willingness to obey an authority figure , even when that obedience caused harm to others. In this article, we'll take a closer look at the Milgram experiment, its significance, and its impact on psychology.
The Milgram experiment was designed to test people's willingness to obey authority, even when that obedience caused harm to others. The study involved three participants: the experimenter, the learner, and the teacher. The learner was actually a confederate of the experimenter, and the teacher was the real participant.
The teacher was instructed to administer electric shocks to the learner whenever the learner gave a wrong answer to a question. The shocks started at a low level and increased in intensity with each wrong answer. The learner was not actually receiving shocks, but they pretended to be in pain and begged the teacher to stop. Despite this, the experimenter instructed the teacher to continue shocking the learner.
The results of the Milgram experiment were shocking. Despite the learner's protests, the majority of participants continued to administer shocks to the maximum level, even when they believed that the shocks were causing serious harm.
The Milgram experiment is perhaps one of the most well-known experiments on obedience in psychology . Milgram's original study involved 40 participants who were instructed to deliver electric shocks to a confederate, who pretended to be receiving shocks.
The shocks were delivered via a "shock machine" and ranged in severity from slight shocks to severe shocks. Despite the confederate's cries of pain and protest, the majority of participants continued to administer shocks up to the maximum level, demonstrating high rates of obedience to authority figures.
Milgram's experiments on obedience generated a great deal of interest and controversy in the scientific community. The results of his study challenged commonly held beliefs about human behavior and the limits of individual autonomy . The study also raised important ethical concerns and spurred a renewed focus on informed consent and debriefing in behavioral research.
In subsequent variations of the experiment, Milgram sought to explore the factors that influenced obedience rates, such as the presence of peers or the proximity of the authority figure. These variations provided further insight into the complex nature of obedience and social influence .
The Milgram experiment remains a significant and influential study in the field of social psychology, providing valuable insights into the power of authority and the limits of individual autonomy. Despite its ethical concerns, Milgram's study continues to be discussed and debated by scholars and students alike, highlighting the enduring impact of this groundbreaking behavioral study.
Who was Stanley Milgram?
Stanley Milgram was a renowned American social psychologist who was born in New York City in 1933. He received his PhD in Social Psychology from Harvard University in 1960 and went on to teach at Yale University, where he conducted his famous obedience experiments. Milgram's research focused on the areas of personality and social psychology, and he is best known for his studies on obedience to authority figures.
Milgram's obedience experiments were controversial and sparked a great deal of debate in the field of psychology. His research showed that ordinary people were capable of inflicting harm on others when instructed to do so by an authority figure. Milgram's work had a profound impact on the field of social psychology and influenced other researchers, such as Philip Zimbardo , to study similar topics.
Milgram's contributions to the field of social psychology were significant, and his obedience experiments remain some of the most well-known and widely discussed studies in the history of psychology. Despite the controversy surrounding his work, Milgram's research continues to be taught in psychology courses around the world and has had a lasting impact on our understanding of obedience, authority, and human behavior.
Milgram's Independent Variables
As we have seen, in Stanley Milgram's famous experiment conducted at Yale University in the 1960s, he sought to investigate the extent to which ordinary people would obey the commands of an authority figure, even if it meant administering severe electric shocks to another person.
The study of obedience to authority figures was a fundamental aspect of Milgram's research in social psychology. To explore this phenomenon, Milgram manipulated several independent variables in his experiment. One key independent variable was the level of shock administered by the participants, ranging from slight shocks to increasingly severe shocks, labeled with corresponding shock levels.
Another independent variable was the proximity of the authority figure, with variations of physical proximity or remote instruction via telephone.
Additionally, the presence or absence of social pressure from others and the authority figure's attire, varying between a lab coat and everyday clothing, were also manipulated.
Through these carefully controlled independent variables, Milgram examined the obedience rates and the level of obedience demonstrated by the participants in response to the concrete situation created in his experiment.
Change of Location
One significant factor that influenced the results of the Milgram experiment was the change of location. Originally conducted at Yale University, the experiment was later moved to a set of run-down offices in Bridgeport, Connecticut. This change had a profound impact on the rates of obedience observed in the study.
In the original experiment at Yale University, the obedience rates were shockingly high, with approximately 65% of participants following the instructions of the authority figure to administer what they believed to be increasingly severe electric shocks to another person. However, when the experiment was relocated to the less prestigious and less authoritative setting of run-down offices, the obedience rates dropped significantly to 47.5%.
This change in location created a shift in the dynamic of the experiment . Participants were less likely to view the authority figure as credible or legitimate in the less prestigious environment. The environment in run-down offices appeared less official and therefore may have weakened the perceived authority of the experimenter. This resulted in a lower level of obedience observed among the participants.
The change in location in the Milgram experiment demonstrated the influence of contextual factors on obedience rates. It highlighted how obedience to authority figures can be influenced by the specific setting in which individuals find themselves. The study serves as a reminder that obedience is not solely determined by individual characteristics but is also shaped by situational factors such as the environment and perceived authority.
In conclusion, the change of location from Yale University to run-down offices had a significant impact on the obedience rates in the Milgram experiment. The move resulted in a drop in obedience, suggesting that the context in which the experiment took place influenced participants' responses to authority .
One important aspect of Stanley Milgram's obedience experiment was the role of the experimenter's uniform, specifically the lab coat. The uniform or attire worn by the authority figure in the experiment played a significant role in influencing obedience levels among the participants.
The lab coat served as a symbol of authority and expertise, creating a sense of credibility and legitimacy for the experimenter. By wearing the lab coat, the authority figure appeared more knowledgeable and trustworthy, which influenced participants to follow their instructions more readily.
The uniform also helped establish a clear power dynamic between the authority figure and the participants. The experimenter's attire reinforced the perception of being in a formal and professional setting, where obedience to authority was expected.
Milgram's experiment included variations to the uniform to examine its impact on obedience levels. In some versions of the experiment, the experimenter wore regular clothing instead of the lab coat. This modification significantly reduced the perceived authority of the experimenter, leading to lower levels of obedience among the participants.
By manipulating the presence or absence of the lab coat, Milgram demonstrated how even a simple change in attire could influence obedience levels . This emphasized the role of external factors, such as the uniform, in shaping human behavior in a social context.
Touch Proximity Condition
In the Touch Proximity Condition of the Milgram experiment, participants were subjected to a unique and intense situation that aimed to test the limits of their obedience to authority. In this particular condition, when the learner refused to participate after reaching 150 volts, the participants were required to physically force the learner's hand onto a shock plate. This manipulation was intended to eliminate the psychological buffer that existed between the participants and the consequences of their actions.
The introduction of touch proximity significantly altered the dynamics of the experiment. The physical act of forcing the learner's hand onto the shock plate made the participants more directly responsible for the pain and discomfort experienced by the learner. This direct physical connection to the consequences of their actions created a profound impact on the participants, leading to a notable decrease in obedience levels.
In the Touch Proximity Condition, obedience rates dropped to just 30%, highlighting the significant influence of the removal of the buffer between the participants and the consequences of their actions. The participants were confronted with the immediate and tangible effects of their obedience, which made it much more difficult to justify their continued compliance.
Overall, the Touch Proximity Condition revealed the critical role that the removal of psychological distance plays in obedience to authority. By eliminating the buffer between the participants and the consequences of their actions, Milgram's experiment demonstrated the tremendous impact that immediate physical proximity can have on individuals' behavior in a difficult and morally challenging situation.
Two Teacher Condition
In Milgram's Two Teacher Condition, participants were given the opportunity to instruct an assistant, who was actually a confederate, to press the switches administering electric shocks to the learner. This variation aimed to investigate the impact of participants assuming a more indirect role in the act of shocking the learner.
Surprisingly, the results showed that in this condition, a staggering 92.5% of participants instructed the assistant to deliver the maximum voltage shock. This high rate of obedience indicated that participants were willing to exert their authority over the assistant to carry out the harmful actions.
The Two Teacher Condition aligns with Milgram's Agency Theory, which suggests that people tend to obey authority figures when they perceive themselves as agents carrying out instructions rather than personally responsible. In this variation, participants may have seen themselves as simply giving orders rather than directly causing harm, which diminished their sense of personal responsibility and increased their obedience.
This condition demonstrates how the dynamic of obedience can change when individuals are given the opportunity to delegate harmful actions to others. It sheds light on the complex interplay between authority figures, personal responsibility, and obedience to explain the unexpected and alarming levels of compliance observed in the Milgram experiment.
Social Support Condition
In the Social Support Condition of Stanley Milgram's experiment, participants were not alone in their decision-making process. They were joined by two additional individuals who acted as confederates. The purpose of this condition was to assess the impact of social support on obedience.
The presence of these confederates who refused to obey the authority figure had a significant effect on the level of obedience observed. When one or both confederates refused to carry out the harmful actions, participants became more likely to question the legitimacy of the authority figure's commands and were less willing to comply.
The specific actions taken by the two confederates involved expressing their refusal to deliver the electric shocks. They openly dissented and voiced their concerns regarding the ethical implications of the experiment. These actions served as powerful examples of disobedience and created an atmosphere of social support for the participants.
As a result, the level of obedience decreased in the presence of these defiant confederates. Seeing others defy the authority figure empowered participants to assert their own autonomy and resist carrying out the harmful actions. The social support provided by the confederates challenged the participants' perception of the experiment as a concrete situation and encouraged them to question the legitimacy of the authority figure's instructions.
Overall, the Social Support Condition demonstrated that the presence of individuals who refused to obey had a profound influence on the level of obedience observed. This highlights the importance of social support in challenging authority and promoting ethical decision-making.
Absent Experimenter Condition
In Stanley Milgram's famous obedience experiment, the proximity of authority figures played a crucial role in determining the level of obedience observed. One particular condition, known as the Absent Experimenter Condition, shed light on the impact of physical proximity on obedience.
In this condition, the experimenter instructed the teacher, who administered the electric shocks, by telephone from another room. The results were striking. Obedience plummeted to a mere 20.5%, indicating that when the authority figure was not physically present, participants were much less inclined to obey.
Without the immediate presence of the experimenter, many participants displayed disobedience or cheated by administering lesser shocks than instructed. This deviation from the experimenter's orders suggests that the absence of the authority figure weakened the participants' sense of obligation and decreased their willingness to comply.
The findings of the Absent Experimenter Condition highlight the significant influence of proximity on obedience. When the authority figure was physically present, participants were more likely to obey, even when faced with morally challenging actions. However, when the authority figure was not in close proximity, obedience rates dramatically decreased. This emphasizes the impact of physical distance on individuals' inclination to follow orders, indicating that proximity plays a crucial role in shaping obedience behavior.
Milgram's Absent Experimenter Condition underscored the importance of physical proximity with authority figures in determining obedience levels. When the experimenter instructed the teacher by telephone from another room, obedience fell to 20.5%, revealing the diminished compliance when the authority figure was not physically present.
Milgram's Legacy and Influence on Modern Psychology
The Milgram experiment was significant for a number of reasons. Firstly, it highlighted the power of obedience to authority, even in situations where that obedience causes harm to others. This has important implications for understanding real-world situations, such as the Holocaust, where ordinary people were able to commit atrocities under the authority of a fascist regime.
Secondly, the experiment sparked a debate about the ethics of psychological research . Some critics argued that the study was unethical because it caused psychological distress to the participants. Others argued that the study's findings were too important to ignore, and that the benefits of the research outweighed the harm caused.
Stanley Milgram's study of obedience is widely recognized as one of the most influential experiments in the history of psychology. Although Milgram faced significant criticism for the ethical implications of his work, the study has had a lasting impact on our understanding of the power of authority and social influence.
Milgram's legacy can be seen in a variety of ways within the field of personality and social psychology. For example, his research has inspired a multitude of studies on the impact of social norms and conformity on behavior, as well as the importance of individual autonomy and free will in decision-making processes.
In addition, Milgram's influence can be seen in modern psychological research that utilizes variations of his study to explore new questions related to social influence and obedience. One such example is the Milgram Re-enactment, which sought to replicate the original study in a more ethical and controlled manner. This variation of the study found that individuals were still willing to administer shocks to the confederate, albeit at lower levels than in Milgram's original study.
Milgram's work has also had a significant impact on the way that researchers approach the treatment of participants in psychological experiments. The ethical concerns raised by Milgram's study led to a renewed focus on informed consent and debriefing procedures, ensuring that participants are aware of the potential risks and benefits of their involvement in research studies.
Milgram's legacy is one of both controversy and innovation. His study of obedience has contributed greatly to our understanding of human behavior and has served as a catalyst for important ethical discussions within the scientific community . While his work may continue to generate debate, there is no doubt that Milgram's contributions to the field of psychology have had a profound and lasting impact.
Milgram's Relationship with Other Prominent Psychologists
Stanley Milgram was a highly influential figure in the field of social psychology, and his work has been cited by a number of other prominent psychologists throughout the years. One of his contemporaries, Albert Bandura, was also interested in the power of social influence and developed the theory of social learning , which explored the ways in which people learn from one another and their environments.
Gordon Allport was another important figure in the field of social psychology, known for his work on personality and prejudice. Allport's research was highly influential in shaping Milgram's own understanding of social influence and obedience.
Milgram's infamous obedience studies demonstrated how individuals could be led to obey authority figures and commit acts that violated their own moral codes. Zimbardo's Stanford Prison Experiment similarly showed how individuals could adopt new identities and exhibit aggressive and abusive behavior when placed in positions of power. Both studies highlight the importance of social context in shaping behavior and have had a significant impact on our understanding of the role of situational factors in human behavior.
Jerome Bruner, another influential psychologist , was known for his work on cognitive psychology and the importance of active learning in education. Although Bruner's work was not directly related to Milgram's study of obedience, his emphasis on the importance of individual autonomy and active learning aligns with some of the key themes in Milgram's work.
Roger Brown, a psychologist known for his research on language and cognitive developmen t, also shared some common ground with Milgram in terms of their interest in human behavior and social influence. Finally, Solomon Asch , another prominent psychologist, conducted important research on conformity that helped to lay the groundwork for Milgram's own study of obedience.
Milgram's work was highly influential and contributed significantly to the field of social psychology. His relationship with other prominent psychologists reflects the collaborative and interdisciplinary nature of psychological research and highlights the ways in which researchers build upon one another's work over time.
Criticisms of the Milgram Experiment
Despite its significance, the Milgram experiment has been heavily criticized by some psychologists. One of the main criticisms is that the study lacked ecological validity - that is, it didn't accurately reflect real-world situations. Critics argue that participants in the study knew that they were taking part in an experiment, and that this affected their behavior.
Another criticism is that the experiment caused psychological distress to the participants. Some argue that the experimenter put too much pressure on the participants to continue administering shocks, and that this caused lasting psychological harm.
The Impact of Milgram's Research on Social Psychology
The Milgram experiment, conducted at Yale University in 1961, shocked the world with its findings on obedience to authority. Despite its groundbreaking contribution to the field of personality and social psychology, the study has also faced significant criticism for its treatment of participants.
Critics have raised concerns about the potential psychological harm inflicted on participants, who were led to believe that they were administering painful electric shocks to a real victim. Nevertheless, the Milgram experiment remains a critical turning point in the history of experiments with people.
It has had a profound impact on psychology, inspiring numerous studies that continue to shed light on obedience, conformity, and group dynamics. It has also sparked important debates about the ethics of psychological research and raised awareness of the importance of protecting the rights and well-being of research participants .
Real-Life Examples of Obedience Leading to Human Catastrophe
Stanley Milgram's obedience experiments have had profound implications for understanding human behavior, especially in contexts where obedience to authority might have contributed to catastrophic outcomes. Here are seven historical examples that resonate with Milgram's findings:
- Nazi Germany : The obedience to authority during the Holocaust, where individuals followed orders to commit atrocities, can be understood through Milgram's experiments. The willingness to administer "lethal shocks" to human subjects reflects how ordinary people can commit heinous acts under authoritative pressure.
- My Lai Massacre : American soldiers massacred hundreds of Vietnamese civilians during the Vietnam War. Milgram's work helps explain how soldiers obeyed orders despite the moral implications, emphasizing the power of authority in a difficult situation.
- Rwandan Genocide : The obedience to ethnic propaganda and authority figures led to the mass killings in Rwanda. Milgram's experiments shed light on how obedience can override personal judgment, leading to an unexpected outcome.
- Jonestown Massacre : Followers of Jim Jones obeyed his orders to commit mass suicide. Milgram's findings on obedience help explain how charismatic leaders can exert control over their followers, even to the point of death.
- Chernobyl Disaster : The obedience to flawed protocols and disregard for safety by the plant operators contributed to the catastrophe. Milgram's work illustrates how obedience to procedures and hierarchy can lead to disaster.
- Iraq War - Abu Ghraib Prison Abuse : The abuse of prisoners by U.S. military personnel can be linked to obedience to authority, a phenomenon explored in Milgram's experiments. The willingness to inflict harm under orders reflects the human participants' compliance in his studies.
- Financial Crisis of 2008 : Blind obedience to corporate culture and regulatory authorities contributed to unethical practices leading to the global financial meltdown. Milgram's insights into obedience help explain how organizational pressures can lead to widespread harm.
These examples demonstrate the pervasive influence of obedience in various historical and contemporary contexts. Milgram's experiments, documented in various Stanley Milgram Papers and the Journal of Abnormal and Social Psychology , continue to be a critical reference in understanding human behavior.
The documentary film "Shocking Obedience" further explores these themes, emphasizing the universal relevance of Milgram's work. His experiments remind us of the human capacity for obedience , even in the face of morally reprehensible orders, and continue to provoke reflection on our own susceptibilities.
Key Takeaways
- The Milgram experiment was a famous and controversial study in psychology that examined people's willingness to obey authority.
- Participants in the study were instructed to administer electric shocks to a learner, even when that obedience caused harm to the learner.
- The results of the study showed that the majority of participants continued to administer shocks to the maximum level, even when they believed that the shocks were causing serious harm.
- The study has been heavily criticized for lacking ecological validity and causing psychological distress to participants.
- Despite the criticisms, the Milgram experiment has had a lasting impact on psychology and has inspired numerous other studies on obedience and authority.
In conclusion, the Milgram experiment remains an important and controversial study in the field of psychology. Its findings continue to influence our understanding of obedience to authority.

- Milgram Experiment: Explaining Obedience to Authority
The Milgram experiment is a classic social psychology study revealing the dangers of obedience to authority and how the situation affects behaviour.
The Milgram experiment, led by the well-known psychologist Stanley Milgram in the 1960s, aimed to test people’s obedience to authority.
The results of the Milgram experiment, sometimes known as the Milgram obedience study, continue to be both thought-provoking and controversial.
The experimental procedure left some people sweating and trembling, leaving 10 percent extremely upset, while others broke into unexplained hysterical laughter.
What finding could be so powerful that it sent many psychologists into frenzied rebuttals?
This study has come in for considerable criticism with some saying its claims are wildly overblown.
Obedience to authority
Stanley Milgram’s now famous experiments were designed to test obedience to authority ( Milgram, 1963 ).
What Milgram wanted to know was how far humans will go when an authority figure orders them to hurt another human being.
Many wondered after the horrors of WWII, and not for the first time, how people could be motivated to commit acts of such brutality towards each other.
Not just those in the armed forces, but ordinary people were coerced into carrying out the most cruel and gruesome acts.
But Milgram didn’t investigate the extreme situation of war, he wanted to see how people would react under relatively ‘ordinary’ conditions in the lab.
How would people behave when told to give an electrical shock to another person?
To what extent would people obey the dictates of the situation and ignore their own misgivings about what they were doing?
The Milgram experiment procedure
The experimental situation into which people were put was initially straightforward.
Participants in the Milgram experiment were told they were involved in a learning experiment, that they were to administer electrical shocks and that they should continue to the end of the experiment.
Told they would be the ‘teacher and another person the ‘learner’, they sat in front of a machine with a number of dials labelled with steadily increasing voltages.
This was the famous ‘shock machine’ in the Milgram experiment.
The third switch from the top was labelled: “Danger: Severe Shock”, the last two simply: “XXX”.
During the course of the Milgram experiment, each time the ‘learner’ made a mistake the participant was ordered to administer ever-increasing electrical shocks.
Of course the learner kept making mistakes so the teacher (the poor participant) had to keep giving higher and higher electrical shocks, and hearing the resultant screams of pain until finally the learner went quiet.
Participants were not in fact delivering electrical shocks, the learner in the Milgram experiment was actually an actor following a rehearsed script.
The learner was kept out of sight of the participants so they came to their own assumptions about the pain they were causing.
They were, however, left in little doubt that towards the end of the experiment the shocks were extremely painful and the learner might well have been rendered unconscious.
When the participant baulked at giving the electrical shocks, the experimenter – an authority figure dressed in a white lab coat – ordered them to continue.
Results of the Milgram shock experiments
Before I explain the results, try to imagine yourself as the participant in the Milgram experiment.
How far would you go giving what you thought were electrical shocks to another human being simply for a study about memory?
What would you think when the learner went quiet after you apparently administered a shock labelled on the board “Danger: Severe Shock”?
How far would you go?
How ever far you think, you’re probably underestimating as that’s what most people do.
Like the Milgram experiment itself, the results shocked.
The Milgram experiment discovered people are much more obedient than you might imagine.
Fully 63 percent of the participants continued right until the end – they administered all the shocks even with the learner screaming in agony, begging to stop and eventually falling silent.
These weren’t specially selected sadists, these were ordinary people like you and me who had volunteered for the Milgram experiment.
Explanation of the Milgram experiment
At the time the Milgram experiment was big news.
Milgram explained his results by the power of the situation.
This was a social psychology experiment which appeared to show, beautifully in fact, how much social situations can influence people’s behaviour.
The Milgram experiment set off a small industry of follow-up studies carried out in labs all around the world.
Were the findings of the Milgram experiment still true in different cultures, in slightly varying situations and in different genders (only men were in the original study)?
By and large the answers were that even when manipulating many different experimental variables, people were still remarkably obedient.
One exception was that one study found Australian women were much less obedient.
Make of that what you will.
Criticism of the Milgram experiment
Now think again.
Sure, the experiment relies on the situation to influence people’s behaviour, but how real is the situation?
If it was you, surely you would understand on some level that this wasn’t real, that you weren’t really electrocuting someone, that knocking someone unconscious would not be allowed in a university study like this Milgram experiment?
Also, people pick up considerable nonverbal cues from each other.
How good would the actors have to be in the Milgram experiment in order to avoid giving away the fact they were actors?
People are adept at playing along even with those situations they know in their heart-of-hearts to be fake.
The more we find out about human psychology, the more we discover about the power of unconscious processes, both emotional and cognitive.
These can have massive influences on our behaviour without our awareness.
Alternative explanation of the Milgram experiment
Assuming people were not utterly convinced on an unconscious level that the experiment was for real, an alternative explanation is in order.
Perhaps the Milgram experiment really demonstrates the power of conformity .
The pull we all feel to please the experimenter, to fit in with the situation, to do what is expected of us.
While this is still a powerful interpretation from a brilliant experiment, it isn’t what Milgram was really looking for.
The influence of the Milgram experiment
Whether you believe the experiment shows what it purports to or not, there is no doubting that the Milgram experiment was some of the most influential and impressive carried out in psychology.
It is also an experiment very unlikely to be repeated nowadays (outside of virtual reality ) because of modern ethical standards.
Certainly when I first came across it, my view of human nature was changed irrevocably.
Now, thinking critically, I’m not so sure.
Milgram experiment repeated
The Milgram experiment has since been repeated by Doliński et al. (2017) , with the same weird result .
Of the 80 people in the study, fully 90% went all the way to the maximum level of electrocution after being ‘ordered’ to by the experimenter.
Dr Tomasz Grzyb, a study author, said:
“…half a century after Milgram’s original research into obedience to authority, a striking majority of subjects are still willing to electrocute a helpless individual.”

Looking back: The making of an (in)famous experiment
Nestar Russell explores the early evolution of Stanley Milgram’s first official obedience to authority experiment.
26 September 2010
In the early 1960s Stanley Milgram (1963) showed that 65 per cent of a sample of ordinary Americans were willing to inflict potentially lethal shocks on an innocent other. Based on documents obtained from Milgram's personal archive at Yale University, I was able to retrace some of the important and unmentioned steps that led to this 'best-known result' (Miller, 1986, p.9).
We all build on the shoulders of those who came before us, and with respect to Solomon Asch, Milgram's obedience experiments were no exception. In his renowned 1951 experiment, Asch demonstrated that a third of all participants would conform to a group of confederates in their provision of obviously incorrect answers on a perceptual line judgement task.
When Milgram describes how his basic experimental procedure evolved, the influence of Asch is clear: I was working for Asch in Princeton, New Jersey, in 1959 and 1960. I was thinking about his group-pressure experiment. One of the criticisms…is that they lack a surface significance, because after all, an experiment with people making judgments of lines has a manifestly trivial content. So the question I asked myself is, How can this be made into a more humanly significant experiment? And it seemed to me that if, instead of having a group exerting pressure on judgments about lines, the group could somehow induce something more significant from the person, then that might be a step in giving a greater face significance to the behavior induced by the group. Could a group, I asked myself, induce a person to act with severity against another person? (Evans, 1980, p.188).
Milgram said he wanted to use group pressure to coerce participants into 'behaving aggressively toward another person' (Tavris, 1974, p.80). Later Milgram (1974, p.148) termed such coercive sources of pressure 'binding factors': powerful bonds that can entrap a person into doing something they might otherwise prefer not to do. He then imagined a situation like Asch's experiment, where a naive participant was placed among a group of actors: …instead of confronting the lines on a card, each one of them would have a shock generator. In other words, I transformed Asch's experiment into one in which the group would administer increasingly higher levels of shock to a person, and the question would be to what degree an individual would follow along with the group (Evans, 1980, pp.188–189). But there was a problem: 'to study the group effect you would also need an experimental control; you'd have to know how the subject performed without any group pressure' (Tavris, 1974, p.80). Asch resolved the problem of requiring an experimental control by running the line-judgement exercise on participants in the absence of the group. However, Milgram was this time unable to draw from Asch's legacy because 'it was not obvious what the inducement would be for a solitary individual to administer shocks in increasing intensities to another person' (Miller, 1986, p.18). According to Milgram, he started 'zeroing in on this experimental control [problem].
Just how far would a person go under the experimenter's orders? It was an incandescent moment… Within a few minutes, dozens of ideas on relevant variables emerged, and the only problem was to get them all down on paper (Tavris, 1974, p.80).
Milgram had his control experiment, but perhaps unwittingly adding 'orders' also introduced a new binding factor: a higher-status person trying to impose their will on someone below them in a hierarchical chain of command.
In support of Milgram's account is an undated archival document (circa 1960) titled 'Studies in Obedience' which describes a rudimentary idea to use a shock device with a 'dial that reads from …light-to-fatal'. He then discusses an initial goal and the main Asch-like coercive technique he intended to deploy to achieve it: 'In order to create the strongest obedience situation use findings of group dynamics' (see also Russell, in press). It seems Milgram was aware that to make his mark and capture the attention of academia, he had to develop an experiment that produced an eye-catching result in the first official publication (after which he could pursue numerous variations in an attempt to unravel why so many obeyed). But what was missing was a rationale as to why the group might agree to hurt an innocent person. Another document also titled 'Studies in Obedience' (circa 1960) with a sketch of a shock 'Panel' (see Figure 1 in PDF version) attempted to address this problem. That is, 'Because of certain possible hazards' the group were to undergo a 'pledge to obey'.
But there is much in this document that Milgram's post-hoc account has failed to mention: a 'War Situation' where one is to adhere to a 'pledge to obey' and all are given a Himmler-like 'Waver [sic] of responsibility', all 'For Germa[n]y'. That Milgram's concerns about the Holocaust – where ordinary Germans later frequently argued they were just following orders – provided the inspiration to invent the obedience experiments has been established (Miller, 1986, p.17). However, the above document illustrates that early in the formulation of his idea he was also attempting to 'cut and paste' into the controlled laboratory setting many of the Nazis' tried and tested techniques of coercion. But in order for Milgram to achieve his unofficial initial goal to 'create the strongest obedience situation', were participants likely to accept a transparently Nazi-sounding 'pledge to obey' orders to inflict severe shocks on an innocent person? The changes that followed would suggest not.
Milgram knew that deceiving participants into thinking they were inflicting shocks on another person was internally likely to generate what he termed strain: intense feelings of tension. He also understood such feelings might detract from his initial goal to create 'the strongest obedience situation'. Milgram countered such feelings by introducing what he would later term strain-resolving mechanisms: measures intended to reduce the tension normally associated with inflicting harm (Milgram, 1974, pp.153–164). For example, instead of a 'pledge to obey', Milgram revealed in his first research proposal (dated October 1960) a new idea: 'Obviously some acceptable rationale must be provided' for inflicting shocks and this was now to be 'achieved by setting the experiment in a context of "social learning".' By contributing to some greater good, Milgram had transformed the infliction of harm from 'something evil' (shocking an innocent person) into something 'good' (advancing human learning) – a strain-resolving conversion process Adams and Belfour (1998, p.xx) termed moral inversion. In this proposal Milgram presented a sketch of the proposed shock device (see Figure 2 in PDF version).
The proposal also mentioned that participants were to be run through the procedure as one of several members of a group or alone. He presumed the group variation 'will cause the critical subject to comply with the experimental commands to a far higher degree than in the "alone" situation' and that, although they might be interesting, the latter's primary purpose was to 'serve as necessary controls for the group experiments'. Building more on Asch's than his own legacy, Milgram's 'Obedience and Group Process' experiments constituted at this time 'the major concern of the present research'.
To assess the idea's viability, Milgram soon after had some of his students build a shock machine (Figure 3 in PDF version), hone the experimental procedure and run the first pilot studies.
The only 'group' pilot Milgram later discussed confirmed his earlier prediction that 'certain persons will follow the group' to the end of the shock board. However, the first test runs of the alone control left him 'astonished' (as cited in Blass, 2004, p.68). Something about the experimenter's commands seemed to render them a far stronger binding factor than he had anticipated.
Perhaps to advance his own legacy, rather than contributing to Asch's, from this point onwards the group force variations were relegated from dominating the research programme to consisting of a couple of minor variations. The 'alone' variations were now to be the main focus.
But there was 'something' about the student-run pilots that Milgram 'was never conviced [sic] of'. He suspected a general lack of professionalism might have tipped some participants off that it was all a ruse. It was of crucial importance that in the official series all participants were convinced the learner was being shocked.
However, one would expect that the more believable the experiments, the more resistant to obeying participants would become. This potential obstacle could defeat Milgram's initial goal to produce a strikingly high completion rate. His solution to this potential problem seems to have been to bombard participants with an array of binding factors and strain-resolving mechanisms that might increase their probability of completing (see Russell, in press).
For example, in a document dated December 1960, Milgram noted that some participants in the pilot mentioned it was the learner's prerogative to 'leave whenever he wants to', and this belief may have emboldened them to stop. Drawing upon his earlier Himmler-like 'Waver [sic] of responsibility', Milgram attempted to reduce the participants' tension regarding their continued participation by proposing: …the following change should be made; … Possible conversation: … EXPERIMENTER: I Have responsibility…go on with the experiment. On 25 January 1961 Milgram completed a second research proposal, which presented several potentially fruitful variations on the basic experimental procedure that, after observing the first pilot studies, Milgram suspected might shed light on why so many participants completed the basic procedure. The variation mentioned first was stimulated by an observation where some participants looked away from the learner, who they could see dimly through a window (Milgram, 1974, pp.33–34), yet continued inflicting shocks. It seemed: '…the salience of the victim may in some degree regulate their performance. This can be tested by varying the "immediacy" of the victim'.
After receiving funding in May 1961, Milgram prepared for a second series of pilot studies and soon after informed his research assistant that the new and improved '[shock] apparatus is almost done and looks thoroughly professional'.
In the second research proposal, while alluding to his initial goal, Milgram asked: 'if one is trying to maximize obedience, is it better to inform a person of the worst of what he may be asked to do at the outset, or is compliance best extracted piecemeal?' Going by the increasing number of switches in Milgram's successive envisioned and actual shock machines from 9 (Figure 1) to 10 (Figure 2) to 12 (Figure 3) to 30 (Figure 4), it would appear Milgram saw merit in the latter. It could be argued these changes represented the inclusion (and extension) of another binding factor that would later become known as the foot-in-the-door technique (Freedman & Fraser, 1966). This is where persons are more likely to agree to a significant request if it is preceded by a comparatively insignificant request.
In late July 1961 Milgram embarked on a second series of pilots that aimed to both eliminate participants' penetrating 'the cover story' and to trial his recent idea to vary the '"immediacy" of the victim'. The two variations piloted were the 'voice feedback' condition (learner could be heard shouting only) and the 'no feed back' condition (after being strapped into the electric chair, the learner could not be seen or heard at all). In the latter condition: 'virtually all subjects, once commanded, went blithely to the end of the board' (Milgram, 1965, p.61).
Thus, by the final pilot Milgram had discovered how he could achieve his initial goal of maximising the completion rate. But near total obedience: deprived us of an adequate basis for scaling obedient tendencies. A force had to be introduced that would strengthen the subject's resistance to the experimenter's commands (Milgram, 1965, p. 61). In the first official experiment Milgram decided participants were to experience a little perceptual feedback – auditory stimulation in the form of wall-banging at the 300- and 315-volt shocks. The intention of this procedural adaptation was to slightly increase the intensity of strain (instead of his usual approach of reducing tension).
On 7 August 1961 Milgram felt confident enough to run the first official 'remote' condition, generating his 'best-known' 65 per cent completion rate. In light of the subtle changes, he probably expected a slightly higher completion rate. Nonetheless, with most participants inflicting every shock, he had still achieved his initial goal of maximising the completion rate. And this result became the centrepiece of Milgram's (1963) (in)famous publication 'Behavioral study of obedience' and had its intended effect.
What can Milgram's study tell us about experimental psychology? Milgram was engaging in the ad hoc trial-and-error exploratory method of discovery, where 'a scientist has no very clear idea what will happen, and aims to find out. He [sic] has a feeling for the "direction" in which to go (increase the pressure and see what happens) but no clear expectations of what to expect' (Harré & Second, 1972, p.69). This is how many major discoveries occur in the pure sciences: often more by accident than design. Dynamite was very unlikely to have come about from hypothesis testing! As Milgram (cited in Evans, 1980, p.191) said: 'Many of the most interesting things we find out in experimentation you don't learn until you carry it out.'
There was nothing underhanded about this approach; as Miller (1986, p.45) has pointed out: 'Given that there was virtually no previous systematic research on obedience, it was understandable that Milgram's focus was essentially in a context of discovery or exploration rather than confirming or disconfirming specific hypotheses'.
As the pictures in this article show, Milgram's indisputably creative idea emerged gradually. Initially it was weak but over time it became a more viable, engaging and truly fascinating project. When reading Milgram's publications one would be forgiven for thinking that he must have woken up one morning with the complete procedure in his head then ran the procedure later on that day. Milgram was clever, but not that clever!
His piloting studies were the seldom mentioned tool that clearly led Milgram to his most fascinating results. Finally, it is important to reiterate that although Milgram may have played an active role in maximising the completion rate in the Remote condition, the official series of experiments were still methodologically very tight. As mentioned, Milgram did not find the student-run pilots totally convincing and it was very important to him that the participants in the official research programme really believed the learner was being shocked. Methodologically, it would seem to me that the obedience research is a very robust series of experiments, and in part that is perhaps why their influence is still felt almost half a century later. - Nestar Russell is at Victoria University of Wellington [email protected]

Stanley Milgram’s experiments on obedience to authority are among the most influential and controversial social scientific studies ever conducted. They remain staples of introductory psychology courses and textbooks, yet their influence reaches far beyond psychology, with myriad other disciplines finding lessons in them. Indeed, the experiments have long since broken free of the confines of academia, occupying a place in popular culture that is unrivaled among psychological experiments. The present article begins with an overview of Milgram’s account of his experimental procedure and findings, before focussing on recent scholarship that has used materials from Milgram’s archive to challenge many of the long-held assumptions about the experiments. Three areas in which our understanding of the obedience experiments has undergone a radical shift in recent years are the subject of particular focus. First, work that has identified new ethical problems with Milgram’s studies is summarized. Second, hitherto unknown methodological variations in Milgram’s experimental procedures are considered. Third, the interactions that took place in the experimental sessions themselves are explored. This work has contributed to a shift in how we see the obedience experiments. Rather than viewing the experiments as demonstrations of people’s propensity to follow orders, it is now clear that people did not follow orders in Milgram’s experiments. The experimenter did a lot more than simply issue orders, and when he did, participants found it relatively straightforward to defy them. These arguments are discussed in relation to the definition of obedience that has typically been adopted in psychology, the need for further historical work on Milgram’s experiments, and the possibilities afforded by the development of a broader project of secondary qualitative analysis of laboratory interaction in psychology experiments.

Milgram Experiment Variations. The Milgram experiment was carried out many times whereby Milgram (1965) varied the basic procedure (changed the IV). By doing this Milgram could identify which factors affected obedience (the DV). Obedience was measured by how many participants shocked to the maximum 450 volts (65% in the original study).

Briefly, a partici-pant and a confederate were told the study concerned the effects of punishment on learning. Through a rigged draw-ing, the participant was assigned the role of teacher while the confederate was always the learner. The participant
Milgram watched everything through a one-way mirror. The role of the " Experimenter " was taken by a stern biology teacher in a lab coat called " Mr Williams ". Milgram employed a confederate (or " stooge ") to help. " Mr Wallace ", a man in his 40s, pretended to be another participant. After a faked coin-toss, Mr Wallace became ...

Milgram's (1963) operational definitions of defiance was any subject who stopped the experiment at any point before the 30th shock level, and obedience, as one who complied with all commands and administers all shocks. Following the experiment, Milgram (1974) interviewed each subject and debriefed them on the true purpose of
