th irt y-f i ve ye ars ag o, one of us
(Philip Zimbardo) launched what is known
as t he Sta nford Prison Ex periment. Twen-
ty-four young men, who had responded to
a newspaper ad calling for participants in
a study, were randomly assigned roles a s
“prisoners” or “guards” in a simulated jail in
Stanford University’s psychology depart-
ment. The “prisoners” were arrested at their
homes by real police of?cers, booked, and
brought to the jail. Everyt hing from the
deliberately humiliating prison uniforms to
the cell numbers on the laboratory doors to
the mandatory strip searches and delousing
were designed to replicate t he depersonal-
izing ex perience of being in a real prison.
The men who were assigned to be guards
were given khaki uniforms, mirrored
glasses, and billy clubs.
The idea was to st udy the psychology
of imprisonment
—
to see what happens
when you put good people in a dehuman-
izing place. But within a matter of hours,
what had been intended as a cont rolled
experiment in human behavior took on a
dist urbing life of its own. After a prisoner
rebellion on the second day of the ex peri-
ment, t he guards bega n using increasingly
degrading forms of punishment, and t he
prisoners became more and more passive.
Each group rapidly took on the behaviors
associated with their role, not because
of any particular interna l predisposition
or instructions from the ex perimenters,
but rather because t he situation it self so
powerfully called for the t wo groups to
assume t heir new identities. Interestingly,
even the ex perimenters were so caught up
in the drama that t hey lost objectiv ity, only
terminating the out-of-cont rol st udy when
an objective outsider stepped in, reminding
them of their dut y to treat the participa nt s
huma nely and ethically. The ex periment,
scheduled to last t wo weeks, ended abrup-
tly after six days.
As we have come to understand the
psychology of evil, we have realized that
such transformations of human charac ter
are not as rare a s we would like to believe.
Historic al inquiry and behavioral science
have demonstrated the “banality of ev il”
—
that is, under certain conditions and
social pressures, ordinary people can com-
mit act s that would ot herwise be unthink-
able. In addition to t he St anford Prison
Ex periment, studies conducted in the 1960s
by Stanley Milgram at Yale University also
revealed the banality of ev il. The Milgram
experiment s asked partic ipant s to play t he
role of a “teacher,” who was responsible for
administering elec tric shocks to a “ learner”
when the learner failed to answer test ques-
tions correc tly. The participants were not
aware that the learner was working with
the ex perimenters and did not actually
receive any shocks. As the learners failed
more and more, the teachers were instruc t-
ed to increase the volt age inten sit y of the
shocks
—
even when t he learners sta rted
screa ming, pleading to have t he shocks
stop, a nd eventually stopped re sponding
altogether. Pressed by the ex periment-
ers
—
serious looking men in lab coat s,
who sa id they’d assume responsibility for
the consequences
—
most participa nts did
not stop administering shocks until they
reached 300 volts or above
—
already in the
lethal range. The majority of teachers deliv-
ered the maximum shock of 450 volts.
We a ll like to think that the line between
good and ev il is impermeable
—
that people
who do terrible things, such a s commit
murder, treason, or kidnapping, are on the
evil side of this line, a nd the re st of us could
never cross it. But the Stanford Prison Ex-
periment a nd the Milgram studies revealed
the permeabilit y of that line. Some people
are on the good side only because situa-
tions have never coerced or seduced them
to cross over.
This is true not only for perpetrators
of tort ure and other horrible ac ts, but for
people who commit a more common kind
of wrong
—
the wrong of ta king no act ion
when ac tion is ca lled for. Whether we con-
sider Nazi Germany or Abu Ghraib prison,
there were many people who observed
what was happening and said nothing. At
Abu Ghraib, one photo shows t wo soldiers
smiling before a pyramid of naked pris-
oners while a dozen other soldiers stand
around watching passively. I f you observe
such abuses and don’t say, “This is wrong!
Stop it!” you give tacit approv al to contin-
ue. You are part of the silent majority that
makes evil deeds more acceptable.
In the Stanford Prison Experiment, for
in st ance, t here were the “good guards” who
maintained the prison. Good guards, on
the shifts when the worst abuses occurred,
never did anyt hing bad to the prisoners,
but not once over t he whole week did
they confront the other guards and say,
“What are you doing? We get paid the
same money without knocking ourselves
out .” Or, “Hey, remember those are college
students, not prisoners.” No good guard
ever intervened to stop the activ ities of the
bad guards. No good guard ever arrived a
minute late, left a minute early, or publicly
complained. I n a sense, then, it’s t he good
guard who allowed such abuses to happen.
The sit uation d ictated their inaction, and
their inaction facilitated evil.
But because ev il is so fascinating, we
have been obsessed with focusing upon and
analyzing evildoers. Perhaps because of
the t ragic ex periences of the Second World
War, we have neglected to consider the ?ip
