In 1961,
social psychologist Stanley Milgram invited volunteers to participate in a
study on memory and learning although the true nature of his experiment was to
investigate obedience to authority. He
told participants that they were randomly assigned to either the role of
teacher or learner when in fact all participants were assigned to be the
teacher as every learner was a paid actor.
The participant and learner were put in separate rooms, so they could
not see each other but could hear each other. The participant was to ask a
series of questions to the learner, and as the teacher they were told to shock
the learner whenever the learner gave an incorrect response. With each
incorrect response, the participant was to increase the shock voltage by 15 volts
with a maximum voltage of 450 volts, which can be lethal. Another confederate, John Williams, was
dressed in a white lab coat and acted as the authority figure in the room
responding that the participant should continue the study if or when they protested. Once the study was completed Milgram reported
that 65 percent of participants repeatedly administered shocks that they
believed caused severe pain and possibly death to the learner.
Milgram conducted
this study because he was interested in trying to explain the behavior of Nazis during the Holocaust. According to Gina Perry,
who is a psychologist and author of a new book entitled Behind the Shock Machine, at the time Milgram’s research was first
published the American public was fascinated by the images of Adolph Eichmann
that they saw on their televisions from his trial. Hannah Arendt, covering the trial, described
his impassivity and ordinariness as terrifying.
Milgram wanted to show that everyone was capable of being both ordinary
and evil if one surrenders his/her will to an authority figure. For many, Milgram seemed to be justifying the
“just following orders” defense of many Nazi perpetrators. Milgram in his 1974 book, Obedience to Authority, argued that
subordinates, such as those under Adolf Hitler, fall into what he described as
a “profound slumber” where a man is
capable of things “alien to his nature,” and feel “virtually guiltless.” Milgram
wanted to re-create this “profound slumber” to see if ordinary people really
engage in evil behavior. And according
to his published article, and later his book, the answer was yes, ordinary
people would engage in evil behavior.
The
reason I’m writing about this experiment is because his experiment is usually
accepted as valid, and then used as evidence of a psychological truth that we
are all inherently evil and that evil will come out when given permission by an
authority figure. But the evidence for
this supposed truth is much less credible than originally thought. Perry discovered
through archival research that the results Milgram published were not always an
accurate portrayal of what he observed in his experiment. Thus his description of Nazi perpetrators
committing crimes in a “zombie-like” state may not be as accurate as his
original publications imply; meaning that the “I was just following orders”
defense may not be as supported by Milgram’s experiment as is usually
believed.
For
example, Milgram wrote in his original article that 65% of participants
conformed to the authority figure and administered severe pain to the
learner. This number implies that there
was one experiment, but what Perry discovered was that Milgram conducted 24
different variations of this experiment and when Perry took into account all of
the variations she found that in over half of the 24 variations a majority of
participants disobeyed the authority figure.
So the statistical evidence is not as straightforward as was presented
by Milgram. Another issue was his
methodology. One reason for conducting a
lab experiment is to have tight controls over all variables so that you can be
certain your independent variable (authority figure) impacted your dependent
variable (shocks) and that your results are not due to some other extraneous
variable. When listening to the audio
recordings, Perry noticed that John
Williams, the individual playing the authority figure in the room, was not
following a clear script. Milgram in his
publications wrote that Williams followed a strict four phrase response to any
questions asked by the participant (teacher) but according to Perry’s research,
Williams often went off-script and commanded subjects up to 25 times to
continue with the experiment. This hurts
the credibility of his findings as that type of behavior shows the researcher
trying to create a certain response, so the participant response is no longer
organic but produced by the researcher. And finally Perry discovered
correspondence between Milgram and his participants after the study was
completed documenting how some participants were suspicious that the scenario
was a hoax. As Perry points out, Candid
Camera was the most popular show on television at the time. For example, participants told Milgram that
the learner cries seemed to come from the corner of the room, like from a tape
recording. Others noted that they
actually decreased the voltage yet the learner’s cries intensified. As Perry writes, the skepticism of the
participants hurts the validity of the study, as the participant’s belief in
the scenario was crucial to measuring how much pain people were willing to
inflict on someone. If participants were
suspicious, they may have demonstrated demand characteristics and simply
started to do what it was clear the researchers wanted.
Perry’s research
is important for us to know about because many believe that Milgram provided solid
evidence to support the supposed truth that we are all ordinary and all capable
of evil. Because once we begin to accept that as true, we begin to act in ways
that corroborate that truth; thus we become self-fulfilling prophecies. Whether you believe that Milgram’s finding
are valid or not, he does provide an important reminder that we should all be
critical readers and thinkers.
