Two of the most famous experiments in psychology, the Stanford prison experiment and Stanley Milgram\u2019s obedience studies, have been called a sham<\/a>, a lie<\/a> and a fraud<\/a>.<\/p>\n

Retraction Watch<\/a>, a site that tracks withdrawn research papers, has hosted an argument<\/a> for retracting the Stanford paper. Psychologists have even been told that almost everything they thought they knew about Milgram is wrong<\/a>.<\/p>\n

Yet interest has not faded. This month, Netflix released six episodes of The New Stanford Prison Experiment<\/a>, putting the 1971 study back in the spotlight. Why do these much-criticised experiments keep drawing us back?<\/p>\n

Part of the answer is how strong the original findings sounded. They came from what is often called the golden age<\/a> of American social psychology, roughly the 1950s to the early 1970s. Researchers in this period ran dramatic experiments on how groups and authority shape what ordinary people do.<\/p>\n

In the 1950s, the psychologist Solomon Asch asked students<\/a> to match the length of a line to one of three others. When a room of actors all gave the same wrong answer, many of the real participants went along with them \u2013 at least some of the time. <\/p>\n

In the early 1960s at Yale University, Stanley Milgram told volunteers<\/a> they were helping with a study of memory and learning. They were asked to give electric shocks \u2013 rising to a level labelled dangerous \u2013 to a man in another room whenever he got a question wrong. <\/p>\n

The shocks were fake and the man was an actor, but the participants did not know that. In the experiment\u2019s initial version, 65% of them went all the way to the top of the scale when a man in a lab coat told them to continue.<\/p>\n

In the late 1960s, the psychologists John Darley and Bibb Latan\u00e9 studied<\/a> why people so often fail to help in an emergency. In one experiment, volunteers heard over an intercom what sounded like another participant having a seizure. The more people they believed could also hear, the less likely each one was to go for help.<\/p>\n

Philip Zimbardo, a Stanford University psychologist who later became president of the American Psychological Association, was the last of these big names. In August 1971, he turned the basement of Stanford\u2019s psychology department into a mock prison. He randomly assigned 24 male students<\/a> to play guards or prisoners in what was meant to be a two-week study.<\/p>\n

He had to stop it after just six days, however, because some of the guards had become overly cruel and some of the prisoners had broken down.<\/p>\n

The critics<\/h2>\n

In a 2019 analysis<\/a> of the Stanford archive, the French researcher Thibault Le Texier argued that Zimbardo\u2019s team gave the guards instructions on how to behave, so they were not acting spontaneously. Some prisoners later said they had exaggerated their distress. The study also began as a student project<\/a>.<\/p>\n

Milgram\u2019s work has also been attacked. One analysis<\/a> argued that he manufactured obedience in the lab rather than discovered it. And psychologists, writing for The Conversation, have pointed out<\/a> that across all versions of his experiment, more people disobeyed than obeyed.<\/p>\n

Some of this criticism, though, is not new, because the researchers disclosed the facts themselves. Zimbardo\u2019s 2007 bestseller, The Lucifer Effect<\/a>, credits his students with the original idea. It also describes how he acted as the prison\u2019s \u201csuperintendent\u201d and briefed and coached the guards.<\/p>\n

The same goes for Milgram. He published the results of many of the variations himself, and noted that obedience fell sharply in some of them. However, those were variations that bore little resemblance to the original experiment setup.<\/p>\n

The harder test is the alternative explanation. Alex Haslam<\/a> of the University of Queensland and Stephen Reicher<\/a> of the University of St Andrews, both social psychologists, have argued for years that obedience alone cannot explain what happened. In 2002, they ran the BBC prison study<\/a>, a televised re-run of Zimbardo\u2019s idea, in which guards did not spontaneously turn cruel. <\/p>\n

They suggest that participants believed in the scientific cause and chose to carry on \u2013 an idea they call \u201cengaged followership\u201d<\/a>. Their explanation has numerous critics<\/a>, however, who say they overlook evidence<\/a> from what was said and done during Milgram\u2019s and Zimbardo\u2019s original sessions. <\/p>\n

Flawed though their experiments may have been by today\u2019s ethical and methodological standards, Zimbardo and Milgram did chance upon something grave and important in human nature. They confronted their participants with a clear moral dilemma: will you choose evil, or will you choose good? And they witnessed ordinary person after ordinary person freely \u2013 albeit agonisingly \u2013 choosing evil.<\/p>\n

That profound and deeply disturbing message is why people keep coming back to these decades-old studies. <\/p>\n

Nothing that Zimbardo, Milgram, their most committed supporters or their fiercest critics have said comes close to fully explaining why ordinary people in their labs tended to choose evil when they could, with no consequence, choose good. <\/p>\n

Of course, many of the pressures that made that fateful choice difficult are now known. But no amount of pressure accounts for the Stanford guards choosing to brutalise their fellows, or Milgram\u2019s participants choosing to give yet another electric shock, when they could have freely chosen otherwise.<\/p>\n

Zimbardo, Milgram and the other studies reveal something monstrous about ordinary human beings \u2013 about us all \u2013 while remaining elusive, enigmatic, almost mysterious. Until we understand why, as Milgram\u2019s experimenter told hesitant participants<\/a>: \u201cThe experiment requires that you continue.\u201d<\/p>\n
