Encyclopedia > Stanford prison experiment

The Stanford prison experiment was ostensibly a psychological study of human responses to captivity and its behavioral effects on both authorities and inmates in prison. It was conducted in 1971 by a team of researchers led by Philip Zimbardo of Stanford University. Undergraduate volunteers played the roles of both guards and prisoners living in a mock prison in the basement of the Stanford psychology building. Psychological science redirects here. ... The term captivity is used to refer to the following meanings: the state of being confined to a space from which it is hard or impossible to escape; see imprisonment. ... Philip G. Zimbardo (born March 23, 1933) is an American psychologist, best known for his Stanford prison experiment and bestselling introductions to psychology. ... “Stanford” redirects here. ...

Prisoners and guards rapidly adapted to their roles, stepping beyond the boundaries of what had been predicted and leading to dangerous and psychologically damaging situations. One-third of the guards were judged to have exhibited "genuine" sadistic tendencies, while many prisoners were emotionally traumatized and two had to be removed from the experiment early.

Ethical concerns surrounding the famous experiment often draw comparisons to the Milgram experiment, which was conducted in 1961 at Yale University by Stanley Milgram, Zimbardo's former high school friend. The following is a list of historically important scientific experiments and observations. ... The experimenter (V) orders the subject (L) to give what the subject believes are painful electric shocks to another subject (S), who is actually an actor. ... “Yale” redirects here. ...

Tom Peters and Robert H. Waterman Jr wrote in 1981 that the Milgram Experiment in the 1960s and the later Zimbardo Experiment were frightening in their implications about the danger which lurks in the darker side of human nature.[1] Thomas J.

Goals and methods

Zimbardo and his team intended to test the hypothesis that prison guards and convicts were self-selecting of a certain disposition that would naturally lead to poor conditions. Participants were recruited via a newspaper ad and offered $15 a day ($75 adjusted for inflation in 2007) to participate in a two-week "prison simulation." Of the 75 respondents, Zimbardo and his team selected 24 males of whom they deemed to be the most psychologically stable and healthy. These participants were predominantly white and middle-class.

The middle class (or middle classes) comprises a social group once defined by exception as an intermediate social class between the nobility and the peasantry. ...

The prison itself was in the basement of the Stanford Psychology Department, which had been converted into a mock jail. An undergraduate research assistant was the "warden" and Zimbardo the "superintendent". Zimbardo set up a number of specific conditions on the participants which he hoped would promote disorientation, depersonalization and deindividuation. In some educational systems, undergraduate education is post-secondary education up to the level of a Bachelors degree. ...

Depersonalization is an alteration in the perception or experience of the self so that one feels detached from, and as if one is an outside observer of, ones mental processes or body. ... Deindividuation refers to the phenomenon of relinquishing ones sense of identity. ...

Guards were given wooden batons and a khaki, military-style uniform that they had chosen at a local military surplus store. They were also given mirrored sunglasses to prevent eye contact. Unlike the prisoners, the guards were to work in shifts and return home during off hours, though at times many would later volunteer for added duty without additional pay. “Truncheon” redirects here. ...

Prisoners were to wear only intentionally ill-fitting muslin smocks without underwear and rubber thong sandals, which Zimbardo said would force them to adopt "unfamiliar body postures" and discomfort in order to further their sense of disorientation. They were referred to by assigned numbers instead of by name. These numbers were sewn onto their uniforms, and the prisoners were required to wear tight-fitting nylon pantyhose caps to simulate shaven heads similar to those of military basic training. In addition, they wore a small chain around their ankles as a "constant reminder" of their imprisonment and oppression.

The day before the experiment, guards attended a brief orientation meeting but were given no formal guidelines other than that no physical violence was permitted. They were told it was their responsibility to run the prison, and they could do so in any way they wished.

Zimbardo provided the following statements to the "guards" in the briefing:

You can create in the prisoners feelings of boredom, a sense of fear to some degree, you can create a notion of arbitrariness that their life is totally controlled by us, by the system, you, me, and they'll have no privacy… We're going to take away their individuality in various ways. In general what all this leads to is a sense of powerlessness. That is, in this situation we'll have all the power and they'll have none. — The Stanford Prison Study video, quoted in Haslam & Reicher, 2003.

The participants who had been chosen to play the part of prisoners were told simply to wait in their homes to be "called" on the day the experiment began. Without any other warning, they were "charged" with armed robbery and arrested by the actual Palo Alto police department, who cooperated in this part of the experiment. Downtown Palo Alto Palo Alto is a city in Santa Clara County, in the San Francisco Bay Area of California, USA. Palo Alto is located at the northern end of the Silicon Valley, and is home to Stanford University (which is technically located in an adjacent area — Stanford, California...

After a relatively uneventful first day, a riot broke out on the second day. The guards volunteered to work extra hours and worked together to break the prisoner revolt, attacking the prisoners with fire extinguishers without supervision from the research staff.

Prisoner counts, initially devised for the prisoners to learn their identity numbers, degenerated to hour-long ordeals where guards tormented the prisoners and imposed physical punishments, including long bouts of forced exercise. The prison became dirty and inhospitable; bathroom rights became privileges, which could be, and frequently were, denied. Some prisoners were forced to clean toilets with bare hands. Mattresses were removed from the "bad" cell block and the prisoners forced to sleep naked on the concrete floor. Moreover, prisoners endured forced nudity and even sexual humiliation.

Zimbardo cited his own absorption in the experiment he guided, and in which he actively participated as Prison Superintendent. On the fourth day, he and the guards reacted to an escape rumour, by attempting to move the entire experiment to a real, unused cell block at the local police station, because it was more secure. The police department refused, citing insurance liability concerns; Zimbardo recalls his anger and disgust with the lack of co-operation, between his and the police's jails.

As the experiment proceeded, several guards became progressively sadistic. Experimenters said that approximately one-third of the guards exhibited genuine sadistic tendencies. Interestingly, most of the guards were upset when the experiment concluded early. Flogging demonstration at Folsom Street Fair 2004. ...

Zimbardo argued that the prisoner participants had internalized their roles, based on the fact that some had stated that they would accept parole even with the attached condition of forfeiting all of their experiment-participation pay. Yet, when their parole applications were all denied, none of the prisoner participants quit the experiment. Zimbardo argued they had no reason for continued participation in the experiment after having lost all monetary compensation, yet they did, because they had internalised the prisoner identity, they thought themselves prisoners, hence, they stayed. To internalize is to put something inside of borders where it did not originally belong. ...

Prisoner 416

A replacement prisoner was introduced; Prisoner No. 416, horrified at the guards' treatment of the other prisoners, went on a hunger strike in an attempt to force his release. Instead, he was forced into a small closet for three hours of solitary confinement.The other prisoners perceived Prisoner 416 as a troublemaker. To exploit this feeling, the guards offered the prisoners a choice: Either the prisoners could give up their blankets, or No. 416 would be kept in overnight solitary confinement. All, but one, of the prisoners chose to keep his blanket. This work is copyrighted. ... This work is copyrighted. ... A hunger strike is a method of non-violent resistance in which participants fast as an act of political protest, or to provoke feelings of guilt or to achieve a goal such as a policy change. ... Solitary confinement, colloquially referred to as the hole (or in British English the block), is a punishment in which a prisoner is denied contact with any other persons, excluding guards, chaplains and doctors. ...

Zimbardo concluded the experiment early when Christina Maslach, a graduate student he was then dating (and later married) objected to the appalling conditions of the prison after she was introduced to the experiment to conduct interviews. Zimbardo noted that of more than fifty outside persons who had seen the prison, Maslach was the only one who questioned its morality. After only six days, of a planned two weeks' duration, the Stanford Prison experiment was shut down.


The Stanford experiment ended on August 20, 1971, only 6 days after it began instead of the 14 it was supposed to have lasted. The experiment's result has been argued to demonstrate the impressionability and obedience of people when provided with a legitimizing ideology and social and institutional support. It is also used to illustrate cognitive dissonance theory and the power of authority. is the 232nd day of the year (233rd in leap years) in the Gregorian calendar. ...

In psychology, the results of the experiment are said to support situational attributions of behavior rather than dispositional attribution. In other words, it seemed the situation caused the participants' behavior, rather than anything inherent in their individual personalities. In this way, it is compatible with the results of the also-famous Milgram experiment, in which ordinary people fulfilled orders to administer what appeared to be damaging electric shocks to a confederate of the experimenter. It has been suggested that this article or section be merged with Situation ethics. ...

Coincidentally, shortly after the study had been completed, there were bloody revolts at both the San Quentin and Attica prison facilities, and Zimbardo reported his findings on the experiment to the U.S. House Committee on the Judiciary.

Criticism of the experiment

The experiment was widely criticized as being unethical and bordering on unscientific. Critics including Erich Fromm challenged how readily the results of the experiment could be generalized. Fromm specifically writes about how the personality of an individual does in fact affect behavior when imprisoned (using historical examples from the Nazi concentration camps). This runs counter to the study's conclusion that the prison situation itself controls the individual's behavior. Fromm also argues that the amount of sadism in the "normal" subjects could not be determined with the methods employed to screen them. For other uses, see Ethics (disambiguation). ... Scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. ...

Piles of bodies in a liberated Nazi concentration camp in Germany Prior to and during World War II, Nazi Germany maintained concentration camps (Konzentrationslager, abbreviated KZ or KL) throughout the territories it controlled. ... Look up sadism in Wiktionary, the free dictionary. ...

Because it was a field experiment, it was impossible to keep traditional scientific controls. Zimbardo was not merely a neutral observer, but influenced the direction of the experiment as its "superintendent". Conclusions and observations drawn by the experimenters were largely subjective and anecdotal, and the experiment would be difficult for other researchers to reproduce. Fieldwork refers to scientific activity conducted in the field, outside the laboratory, of subject matter in an as-found state, by anthropologists, geologists, botanists, archaeologists or others who study the natural or human world. ...

Some of the experiment's critics argued that participants based their behavior on how they were expected to behave, or modeled it after stereotypes they already had about the behavior of prisoners and guards. In other words, the participants were merely engaging in role-playing. In response, Zimbardo claimed that even if there was role-playing initially, participants internalized these roles as the experiment continued. This work is copyrighted. ... This work is copyrighted. ... For the term used in computing, see stereotype (UML). ... In role-playing, participants adopt characters, or parts, that have personalities, motivations, and backgrounds different from their own. ... To internalize is to put something inside of borders where it did not originally belong. ...

Additionally, it was criticized on the basis of ecological validity. Many of the conditions imposed in the experiment were arbitrary and may not have correlated with actual prison conditions, including blindfolding incoming "prisoners", not allowing them to wear underwear, not allowing them to look out of windows and not allowing them to use their names. Zimbardo argued that prison is a confusing and dehumanizing experience and that it was necessary to enact these procedures to put the "prisoners" in the proper frame of mind; however, it is difficult to know how similar the effects were to an actual prison, and the experiment's methods would be difficult to reproduce exactly so that others could test them. Ecological validity is one of the forms of validity for an experiment. ...

Some said that the study was too deterministic: reports described significant differences in the cruelty of the guards, the worst of whom came to be nicknamed "John Wayne." (This guard alleges he started the escalation of events between "guards" and "prisoners" after he began to emulate a character from the Paul Newman film Cool Hand Luke. He further intensified his actions because he was nicknamed "John Wayne" though he was trying to mimic actor Strother Martin who played the role of the sadistic "Captain" in the movie.[2]) Other guards were kinder and often did favors for prisoners. Zimbardo made no attempt to explain or account for these differences. Determinism is the philosophical proposition that every event, including human cognition and behavior, decision and action, is causally determined by an unbroken chain of prior occurrences. ... This article is about the American actor and race team owner. ... Cool Hand Luke is a 1967 American film starring Paul Newman and directed by Stuart Rosenberg. ... Strother Martin, (March 26, 1919 – August 1, 1980) was an American character actor in numerous films and television programs. ...

Lastly, the sample size was very small, with only 24 participants taking part over a relatively short period of time.

Haslam and Reicher

Alex Haslam and Steve Reicher (2003), psychologists from the University of Exeter and University of St Andrews, conducted a partial replication of the experiment with the assistance of the BBC, who broadcast scenes from the study as a reality TV program called The Experiment. Their results and conclusions were very different from Zimbardo's and led to a number of publications on tyranny, stress and leadership (moreover, unlike results from the SPE, these were published in leading academic journals; e.g., British Journal of Social Psychology, Journal of Applied Psychology, Social Psychology Quarterly) . While their procedure was not a direct replication of Zimbardo's, their study does cast further doubt on the generality of his conclusions. Specifically, it questions the notion that people slip mindlessly into role and the idea that the dynamics of evil are in any way banal. Their research also points to the importance of leadership in the emergence of tyranny (of the form displayed by Zimbardo when briefing guards in the Stanford experiment).

Abu Ghraib

When the Abu Ghraib military prisoner torture and abuse scandal was published in March 2004, many observers immediately were struck by its similarities to the Stanford Prison experiment — among them, Philip Zimbardo, who paid close attention to the details of the story. He was dismayed by official military and government efforts shifting the blame for the torture and abuses in the Abu Ghraib American military prison on to "a few bad apples" rather than acknowledging it as possibly systemic problems of a formally established military incarceration system. Wikimedia Commons has media related to: Abu Ghraib prisoner abuse Beginning in 2004, accounts of abuse, rape, although this has not been proven,[1], homicide[2], and torture of prisoners held in the Abu Ghraib prison in Iraq (also known as Baghdad Correctional Facility) came to public attention. ...

Eventually, Zimbardo became involved with the defense team of lawyers representing Abu Ghraib prison guard Staff Sergeant Ivan "Chip" Frederick.

Zimbardo drew on his knowledge gained from participating in SSG Frederick's case to write The Lucifer Effect: Understanding How Good People Turn Evil, (Random House, 2007), dealing with the many alleged connections between the Stanford Prison Experiment and the Abu Ghraib abuses.[4]

She had walked into the experiment late and therefore was more likely to be startled than those who had been planning it for months and observing it for five days, she said.
Later, when she looked at the monitor of the prison yard again, she asked someone to point out John Wayne and was shocked to discover it was the young man she had talked with earlier.
In Zimbardo's view, prisons are "failed social-political experiments" that continue to bring out the worst in relations between people "because the public is indifferent to what takes place in secret there, and politicians use them, fill them up as much as they can, to demonstrate only that they are tough on crime.
