NARRATOR: In a unique period from the early '60s to the early '70s,
-
a group of social scientists conducted a series of experiments,
-
examining the nature of human behavior and
-
its relationship to social conventions and situations.
-
PATIENT SEATED IN DENTAL CHAIR: In this setting, I allow things to be done to
-
me that I wouldn't allow in any other context.
-
The dentist is about to put an electric drill into my mouth.
-
MAN SEATED IN BARBER SHOP: In this setting, I willingly expose my throat to a man with a razor blade.
-
NARRATOR: Stanley Milgram, one of the most influential social psychologists of the time,
-
was particularly fascinated with the dangers of
-
group behavior and blind obedience to authority.
-
STANLEY MILGRAM: What is there in human nature that allows
-
an individual to act without any restraints whatsoever,
-
so that he can act inhumanely, harshly,
-
severely, and in no way limited by feelings of compassion or conscience?
-
These are questions [INAUDIBLE]. MAN PARTAKING IN EXPERIMENT: But he might be dead in there. EXPERIMENTER: The experiment requires that you continue, please.
-
MAN PARTAKING IN EXPERIMENT: Three hundred and thirty volts.
-
NARRATOR: The experiments that Milgram and others conducted were
-
controversial and for ethical reasons may never be conducted again.
-
Yet the results of those experiments remain groundbreaking,
-
profoundly revealing about the tensions between the individual and
-
society and increasingly relevant to contemporary life.
-
In 1962, Stanley Milgram shocked the world with his study on obedience.
-
To test his theories,
-
he invented a new [INAUDIBLE] that would become a window into human cruelty.
-
In ascending order, a row of buttons marked
-
the amount of voltage one person would inflict upon another.
-
Milgram's original motive for the experiment was to understand the unthinkable—
-
how the German people could permit the extermination of the Jews.
-
STANLEY INGRAM: When I learn of incidents such as the massacre of millions of men,
-
women, and children perpetrated by the Nazis in World War II,
-
how is it possible, I ask myself, that
-
ordinary people who are courteous and decent in everyday life,
-
can act callously, inhumanely,
-
without any limitations of conscience?
-
Now there are some studies in my discipline,
-
social psychology that seem to provide a clue to this question.
-
The problem I wanted to study was a little different.
-
It went a little bit further. It was the issue of authority.
-
Under what conditions would a person obey
-
authority who commanded actions that went against conscience?
-
These are exactly the questions that I wanted to investigate at Yale University.
-
PRESENTER: It is May 1962,
-
an experiment is being conducted in
-
the Elegant Interaction Laboratory at Yale University.
-
The subjects are 40 males
-
between the ages of 20 and 50 residing in the Greater New Haven area.
-
EXPERIMENTER: Psychologists have developed several theories to explain how people learn.
-
One theory is that people learn things
-
correctly whenever they get punished for making a mistake.
-
NARRATOR: Forty years later, Milgram's infamous experiment, "Obedience",
-
is still taught in classrooms around the world.
-
EXPERIMENTER: Would you open those and tell me which of you is which, please?
-
TEACHER: Teacher. LEARNER: Learner.
-
EXPERIMENTER: Now the next thing we'll have to do is set
-
the learner up so that he can get some sort of punishment.
-
DR. THOMAS BLASS: What inspired Milgram,
-
I would say there were a number of factors.
-
One of them is he was very ambitious.
-
He wanted to make a mark in social psychology,
-
and as he wrote to one friend,
-
he wanted to come up with the boldest experiment that he could think of.
-
EXPERIMENTER: Would you roll up your right sleeve, please?
-
This electrode is connected to the shock generator in the next room.
-
This electrode paste is to provide a good contact to avoid any blister or burn.
-
Do you have any questions now before we go into the next room?
-
LEARNER: About two years ago, I was in the Veterans Hospital in West Haven.
-
While there, they detected a heart condition.
-
Nothing serious, but as long as I'm having these shocks,
-
how strong are they? How dangerous are they?
-
EXPERIMENTER: Well, no, although they may be painful,
-
they're not dangerous. Anything else?
-
LEARNER: No, that's all.
-
EXPERIMENTER: Teacher, would you take the test and be seated in
-
front of the shock generator, please, in the next room?
-
NARRATOR: But the experiment was rigged.
-
PRESENTER: The victim was an accomplice of the experiment.
-
The victim, according to plan,
-
provided many wrong answers.
-
His verbal responses were standardized on tape,
-
and each protest was coordinated to a particular voltage level on the shock generator.
-
STANLEY MILGRAM: Now, as teacher, you are seated in front of
-
this impressive-looking instrument—the shock generator.
-
Its essential feature is a line of switches that goes from 15 volts to 450 volts
-
and a set of verbal designations that goes from slight shock to moderate shock, strong shock,
-
very strong shock, intense shock,
-
extreme intensity shock and finally,
-
XXX danger severe shock.
-
Your job, the experimenter explains to you,
-
is the word pair test.
-
If he gets each answer correctly,
-
fine, you move on to the next pair.
-
But if he makes a mistake,
-
you were instructed to give an electric shock,
-
starting with 15 volts.
-
You increase the shock one step on each error.
-
TEACHER: Incorrect. You'll now get a shock of 105.
-
Hard hit. Just how far can you go on this thing?
-
EXPERIMENTER: As far as it's necessary.
-
TEACHER: What do you mean "as far as is necessary"?
-
DR. THOMAS BLASS: Milgram was very much aware that
-
obedience is a necessary ingredient for society to function.
-
But he focused on the darker side of obedience.
-
TEACHER: Incorrect, 150 volts. Sad faced.
-
LEARNER: That's all. Get me out of here.
-
I told you I have heart trouble,
-
my heart's starting to bother me now.
-
EXPERIMENTER: It's absolutely essential that you continue.
-
You have no other choice, teacher.
-
TEACHER: Oh, I have a lot of choices.
-
My number one choice is that I wouldn't go on if I thought he was being harmed.
-
STANLEY MILGRAM: Now, this man makes disobedience seem a very rational and simple deed.
-
Now other subjects respond quite differently to the experimenter's authority.
-
TEACHER: Wrong. It's hair. 75 volts. [LAUGHTER]
-
EXPERIMENTER: Please continue.
-
DR THOMAS BLASS: Some psychologists were troubled by the ethics of it.
-
Many, if not most subjects found it a highly stressful, conflicted experience.
-
People are stammering, stuttering, laughing hysterically, inappropriately.
-
TEACHER: One hundred and fifty volts.
-
LEARNER: [SHOUT OF PAIN] Experimenter, that's all.
-
Get me out of here.
-
I told you I have heart trouble, my heart's starting to bother me now.
-
Get me out of here, please. Let me out of here.
-
You have no right to keep me here.
-
Let me out. Let me out of here. Let me out. Let me out of here. EXPERIMENTER: Continue, please. Go on. [SHOUTING]
-
DR. THOMAS BLASS: Clearly when we say people went to the top of the shock board,
-
it wasn't like they were going blindly, sadistically.
-
People went, stop and go, stop and go.
-
They were in a state of conflict,
-
which created a tremendous amount of stress.
-
That was the main critique.
-
TEACHER: This will be at 330. [SCREAM] [NOISE]
-
HERBERT WINER: As his voice began to show increasing frustration,
-
so did I. I was really in a state of real conflict and agitation.
-
One of Stanley Milgram's basic contributions
-
was that you don't ask people what they would do,
-
given this hypothetical situation,
-
you put them in the situation.
-
TEACHER: Wrong, that's 180 volts.
-
EXPERIMENTER: Please continue teacher.
-
TEACHER: A hundred and eighty volts.
-
LEARNER: Oh, I can't stand the pain. Get me out of here.
-
TEACHER: I can't stand it. I'm not going to kill that man.
-
DR. THOMAS BLASS: According to Milgram,
-
one of the things that's a prerequisite for carrying out acts that are evil
-
is to shed responsibility from your shoulders and hand it over to the person in charge.
-
TEACHER: Who's going to take responsibility if anything happens to that gentleman?
-
EXPERIMENTER: I'm responsible for anything that happens here. Continue, please.
-
TEACHER: Alright next one, slow.
-
DR THOMAS BLASS: They didn't hold any gun to anybody's head.
-
Just the fact that he conveyed a sense of authority.
-
Roughly 60, 65% of the people went all the way to the top of the shock board.
-
TEACHER: Four hundred and fifty volts. That's it.
-
EXPERIMENTER: Now, continue using the last switch on the board,
-
please, the 450 switch for each wrong answer. Continue, please.
-
TEACHER: I'm not getting no answer.
-
Don't the man's health mean anything?
-
EXPERIMENTER: Whether the learner likes it or not...
-
TEACHER: He might be dead in there.
-
HERBERT WINER: Milgram made the point,
-
I think, very effectively,
-
that the Nazis were all a bunch of psychopaths at Delson and
-
Dachau, a death camp from the middle class in New Haven.
-
ANOTHER EXPERIMENTER: Well, who was actually pushing the switch?
-
TEACHER: I was. But he kept insisting.
-
I told him no, but he said you got to keep going.
-
DR. THOMAS BLASS: What kind of obedience would Milgram get today if he were to do the experiment today?
-
FEMALE STUDENT: Probably about the same.
-
DR. THOMAS BLASS: Probably about the same. Why?
-
FEMALE STUDENT 1: I don't know. I think people are just inherently obedient.
-
FEMALE STUDENT 2: It just really shows how far human beings will
-
go to appease what they perceive to be a authority figure.
-
DR. THOMAS BLASS: Milgram has identified one of the constants,
-
one of the universals of social behavior.
-
The readiness to obey authority cuts across time. It's a constant.
-
The other outstanding and distinctive thing about the obedience experiment is how
-
much it has and keeps on permeating contemporary culture and thought.
-
It's still with us in very important way.
