Seven Things You Didn’t Know About Milgram

By Neuroskeptic | December 26, 2008 10:30 am

There’s been a lot written about psychology professor Jerry Burger’s recent replication of the famous “obedience” experiments first carried out by Stanley Milgram in the early 1960s. Here’s Burger’s paper in which he reports that obedience rates are almost the same today as they were nearly 50 years ago.

Wikipedia’s page on this experiment has an excellent summary of the methodology and results of the original study if you’re not familiar with it.

It’s a testament to the importance of the original obedience experiment that many who know nothing else about psychology have at least heard of it, and it’s common knowledge that Milgram found that a startlingly high proportion of ordinary volunteers were willing to administer very strong “shocks” to an innocent victim, on the orders of the experimenter. But there’s much more to the “Milgram Experiment” than many people realize. So – read on. That’s an order.

  1. There wasn’t just one experiment In 1974, Milgram discussed the results and implications of his research in a book, Obedience to Authority: An Experimental View. (The cover is rather amusing). In it he describes no fewer than 19 different experiments, not including pilot studies. Most of the studies included 40 participants, although some of the later ones used 20. The basic nature of the experimental situation was the same in each case, but important factors were varied between expriments, offering some insight into the conditions which drive obedience (see below). All of this work was performed at or near Yale between 1960 and 1963. Milgram also refers to later replication studies carried out in“Princeton, Munich, Rome, South Africa and Australia” where “the level of obedience was invariably somewhat higher than that found [in the Yale studies]“. So, whatever was going on in the Milgram experiments, it wasn’t unique to the USA, and the fact that Jerry Burger has just obtained very similar results shows that it wasn’t unique to the 1960s either (although, to look at it the other way, the USA today is not especially conformist.)
  2. Subjects were paid $4 each Milgram’s book is full of details such as this, including plenty of photos and drawings illustrating what happened. The picture here shows the designated “victim” in most of the experiments – James McDonough, “a 47-year old accountant, trained for the role; he was of Irish-American descent and most observers found him mild-mannered and affable”. This is the face that launched a thousand shocks – seeing it, for me, brought home the results of the obedience studies very starkly. How could anyone shock that guy? Another important detail is that rather than recruiting undergraduate students, as most psychology experiments do, Milgram placed adverts in local newspapers and, when that only got a few hundred volunteers, resorted to cold-calling names in the New Haven telephone directory. This meant that the participants were (as far as possible) representative of the normal population – a crucial point.
  3. Milgram was an Evolutionary Psychologist Well, sort of. He was into Evolutionary Psychology before it became a buzzphrase – indeed, before the term had been coined. In his book, Milgram notes that “the formation of hierarchically organised groupings lends enormous advantage to those so organized in coping with dangers of the physical environment, threats posed by competing species, and potential disruption from within.” In other words, an animal which has the ability to submit to authority when necessary might be more likely to survive than one which was stubbornly individualistic. He goes on to theorize that humans have evolved a psychological mechanism for obedience, which he calls the “Agentic State”, a special state of mind in which our normal moral inhibitions are bypassed and we become an agent of an authority. I’m not sure many people would buy this as a good explanation, and it isn’t clear if Milgram’s evolutionary logic relies on Group Selection theory, but it’s certainly interesting.
  4. It was stressful Most of the subjects were acutely distressed during the procedure – hardly surprising given the screams and protests of their “victim”. Some subjects shook with tension; one started laughing whenever they had to give a shock. Yet most of them continued to give the shocks despite being tangibly upset about it. They didn’t want to hurt the “victim” – but they did. This inner conflict suffered by the subjects comes across vividly in Milgram’s writing, and it led to some fascinating behaviour. In Experiment 7, in which the “experimenter” giving orders left the room and spoke to the subjects by telephone, many subjects continued to give shocks but gave much milder shocks than they were supposed to. In other words, they were unwilling to hurt the victim but also unwilling to openly disobey (although in this case, 80% of subjects eventually did). Most people also seemed to try to keep the shocks as short as possible, and tried to minimize the number of punishments by helping the victim to give the right answers. Milgram argued that this ruled out the view that his experiment showed people to be “aggressive” or “sadistic” – rather, people were naturally averse to causing harm, but the situation they found themselves in led them to do so anyway. As he put it “The social psychology of this century reveals a major lesson: often it is not so much the kind of person a man as the kind of situation in which he finds himself that determines how he will act.”
  5. There was follow-up Milgram’s sometimes accused of being a cavalier or even callous researcher who exposed his volunteers to emotional harm. In fact although, as the cliche goes, Milgram’s studies would never pass an ethics committee today, he seems (at least on his own account) to have gone to great effort to ensure that his participants were not traumatized and to record how they felt about the experiment. Immediately after the experiment was finished the subjects were “debriefed” and told what had really happened; if they had been obedient, they were reassured that this was normal behaviour (true, of course). Then, a few weeks later, they were sent a write-up of the results of the research and an explanation of the rationale. A questionairre asked how they felt about the study overall; 43% said they were very glad to have done it, 40% said they were glad, and just 1.3% were sorry or very sorry to have done it; there was little difference between those who obeyed and those who didn’t. Commenting on the fact that people seemed remarkably relaxed about what they had done, in retrospect, Milgram wryly noted “The same mechanisms that allow the subject to perform the act…continue to justify his behaviour for him”.
  6. Not everyone obeyed You probably already know this, but you think of it as less exciting than the fact that most people did. In the best known version of the experiment (Experiment 5), 35% of people refused to administer the highest shock level, and some of those came close to it. In other experimental set-ups, obedience rates were different – when the study was carried out in a run-down city apartment, rather than in the presitgous surroundings of Yale, obedience rates dropped (but were still 47.5%). When the subjects did not have to administer the shocks themselves but simply sit by and take notes while someone else did, almost everyone complied (92.5%). Yet there were no clear explanations for why some individuals obeyed and some did not. Some people were chillingly obedient, others were boldly defiant, but it’s not clear why. Age, religion (Catholic vs. Protestant), and political affiliation did not seem to matter. Most of the studies used male volunteers only, for some reason, but Experiment 8 used women; compared to Experiment 5 the results were pretty much identical. In the early experiments there were some indications that better educated and higher-status men were more defiant, but this did not seem to hold for all of the studies.
  7. This actually happened Again, you already knew this, but it’s worth taking a moment to remember it. This really happened and it’s been replicated ad nauseum; so far as I can see, no-one has succesfully criticized the basic assumptions of the paradigm (although if anyone has please let me know.) Milgram’s faith in humanity seems to have been shaken by his research – his book contains case studies of individual participants which are are cynical to the point of misanthropy, even down to the level of the physical appearance and personality of the participants (“Mr Batta is a 37-year old welder…he has a rough-hewn face that conveys a conspicuous lack of alertness. His overall appearance is somewhat brutish…[during the experiment] what is remarkable is his total indifference to the learner; he hardly takes cognizance of him as a human being…the scene is brutal and depressing…at the end of the session he tells the experimenter how honored he has been to help him.”) The subjects who disobeyed authority get a slightly better treatment, but not much better. Yet who can blame Milgram for this? It’s worth bearing in mind also that Milgram was Jewish. His text is full of references to Nazi Germany, Hannah Arendt, the Vietnam War and the Mai Lai massacre. The hero of the book, if there is one, seems to be the young man who took part in the experiment and, as a result, decided to apply for Conscientous Objector status to avoid being sent to Vietnam. He got it.

    Good stuff. I read the Milgram book back in undergrad (I wasn’t even a psych major tho, clearly I *do* belong in grad school) and I thought it very good. I’m not so sure about saying Milgram was an evolutionary psychologist. If by that you mean, ‘Milgram thought evolution was relevant to psychology’ then it’s true but it rather denudes the term. (In that sense, Darwin was clearly an evolutionary psychologist, which I don’t think helps matters much).

    Well I was exaggerating slightly yes – but it’s interesting that despite being famous for showing the influence of social pressures on behavior, he didn’t write off the importance of biology. Although I happen to think his biological speculation wasn’t convincing.

    Great post. I’m often surprised at the number of people I come across who have never been exposed to Milgram’s work and are shocked at what happened in the study. (Or as your post points out, studies.) These kinds of findings give us all a reason/opportunity to ask some penetrating questions about who we are as people.

    Thanks. What I find odd is that the participants in Burger’s study didn’t work out what was going on… either they had never heard of Milgram or they just didn’t make the mental link with what they were doing

    not exactly a full blown criticism in the sense you mean, but I went to this seminar and it is an interesting (if, in my opinion, onyl semi-plausible) idea. Sorry I don’t have the full paper, but I’m sure you can track it down from this abstract:JAN DE VOS (Ghent University, Belgium) PSYCHOLOGIZATION FROM MILGRAM TO ZIMBARDO: FROM ACTING OUT TO “PASSAGE À L’ACTE”? (Stanley Milgram’s first article on his famous experiment was rejected by scientific journals for leading to no conclusions about obedience and being merely “a triumph of social engineering”. The experiment indeed seems an enactment; prefiguring today’s psychotainment, and the Candid Camera disclosure at the end brought relief but no understanding whatsoever. Milgram rewrote the article, engaging in the classic classification of trivia, and more or less saved his academic career. Departing from this the Milgram experiment can be seen as an ‘acting out’ of the post-war psychologization waves sweeping through western societies. The question is Zimbardo’s Stanford Prison Experiment merely repeating Milgram? Or does Milgram’s acting out Shift, with Zimbardo, to a “passage à l’acte” (a much more extreme flight from representation)? Does not Zimbardo, disclosing the psychological meaning of the experiment from the very beginning, mark the appearance of newer late-modern forms of psychologization in their relation with contemporary forms of abuse of power and torture?) Jan De Vos has written on psychologization for Journal of Lacanian Studies and International Journal of Zizek Studies. A draft paper for this seminar on 3 December is available temporarily at http://www.discourseunit.com/jandevos.doc and Jan will rehearse main themes in this paper and explore the thesis that Zimbardo’s stance can be understood as a passage à l’acte in the opening presentation for about 30 minutes at his presentation to give plenty of time for discussion, so we strongly recommend that you download and read the draft paper beforehand. greg

    Ooh that does look interesting – always good to know the story behind the scenes of a book such as this one.But…I’m not sure about this “International Journal of Zizek Studies”. He’s not even dead yet!

  • Anonymous

    he might not be dead, but he does have a supermodel for a girlfriend and that was always likely to end in him having his own journal. probably.

    Anyway, I returned to this because I noticed a nice little aside has appeared about milgram on wikipedia.

    Some economist (this is what social psychologists are calling themselves these days it seems, at least freakonomics seems like fairly standard social psy to me) has put forward an alterative theory:

    It is not that people are obeying, more that they make a rational judgement that experts usually make good decisions, people don’t suffer serious consequences from them and so people listen to them and believe them (I think he is specifically talking about the dot-com buddle and the housing crisis). In the case of Milgram, that judgement would actually have been 100% correct.

    Nice conclusion, made me smile.

    That’s a clever point, but I don’t quite buy it. In the book Milgram describes in great detail just how upset the obedient participants were, during and immediately after the experiment. They clearly believed that what they were doing was causing pain. But they still obeyed. It’s not like they knew it was all an act… although, of course, in fact it was.

    I would love to perform the Milgram experiments on autistics. My hunch says that obeying authority is a function of the oxytocin system and autistics should comply less often. Then give them oxytocin and see if they comply more. Science, get on that!

    Re criticism of the paradigm: someone told me they thought all Milgram showed was that people don't believe the researcher would actually let them hurt people, because our society simply doesn't do that, and that similar studies in China found people failing to comply more readily because they were more able to accept that authority endorsed torture was possible. I didn't check out the China stuff because I knew the Milgram participants showed huge stress, and you might have to argue the stress was due to pressure on their reality rather than over the prospect hurting someone. Has this challenge been dealt with?
