Milgram’s obedience experiment is one of the most useful examples to illustrate the strengths and limitations of laboratory experiments in psychology/ sociology, as well as revealing the punishingly depressing findings that people are remarkably passive in the face of authority…
This post outlines details of the original experiment and two recent, televised repeats by the BBC (2008) and for Darren Brown’s ‘The Heist’ (2014).
The Original Obedience 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.
The video below is quite long, but you can selectively watch it to get an idea of the procedure (which is outlined below)
Volunteers were recruited for a lab 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, who was actually an associate 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 grey lab coat, played by an actor.
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” was strapped to a chair with electrodes. After he has learned a list of word pairs given 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 4 prods and if one was not obeyed then the experimenter 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.
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).
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.
Despite the many ethical pitfalls of this experiment, some participants still believed the benefits outweighed the costs – below is the view of one participant…“While I was a subject in 1964, though I believed that I was hurting someone, I was totally unaware of why I was doing so. Few people ever realize when they are acting according to their own beliefs and when they are meekly submitting to authority… To permit myself to be drafted with the understanding that I am submitting to authority’s demand to do something very wrong would make me frightened of myself… I am fully prepared to go to jail if I am not granted Conscientious Objector status. Indeed, it is the only course I could take to be faithful to what I believe. My only hope is that members of my board act equally according to their conscience…”
More recent video repeats of the Milgram experiment:
The BBC did a documentary in 2008 in which 12 people were subjected to what seems to be the same experiment, and a similar results found. Vimeo link here.
Darren Brown also did a more recent re-run of the Milgram obedience experiment in order to test people’s responses to authority as part of his 2014 programme ‘The Heist’ – interestingly in this, one participant says they can’t carry on because they’ve heard of the experiment (even though they seem to have started it), while another who hadn’t heard of it comments that they needed more buttons on the shock machine.
Strengths and Limitations of Milgram’s Obedience Experiment
The above experiment illustrates many of the advantages and disadvantages of using laboratory experiments in psychology and sociology.
Some of the obvious advantages include the fact that it’s got excellent reliability, given the similar results gained on the two repeats, and it’s still a useful tool for waking us up to just how quiescent to authority many of us are, challenging theories such as the flight from deference.
It also illustrates many of the limitations of experiments – it is still extremely artificial, not true to real life because authority manifests itself in vastly different ways (as teachers, police and so on, not scientists), and the Hawthorne Effect is very nicely illustrate in the Darren Browne clip above (seriously has not EVERYONE heard of the Milgram experiment by now?!, or is that just my middle class cultural bias?), and then of course, there’s the ethics – Darren Browne actually comments that it took one of the respondents too long to recover from the experiment, so he doesn’t select her for the next stage of ‘The Heist’.
