THE BASEMENT
A Narrative of the Stanford
Prison Experiment
August 14–20, 1971 •

Stanford Prison Experiment
I.
THE VOLUNTEERS
They came for the money.
Twenty-four young men, chosen from a pool of
seventy-five college students, each paid fifteen dollars a day to play a game.
That was the word used in the recruitment flyers tacked to cork-boards in the
sun-washed corridors of Stanford University in the summer of 1971: game. A
psychological study of prison life. Two weeks. Fifteen dollars a day. No
criminal record required.
The sky was still blue when they signed their names.
Professor Philip Zimbardo stood among them with the
quiet authority of a man who believed he was about to illuminate something
profound about human nature. He was thirty-eight years old. He had tenure. He
had a theory. He believed that institutions corrupt — that the uniform, the
role, the architecture of power could transform ordinary, healthy young men
into something unrecognizable.
He had no idea how quickly he would be proven right.
By a coin flip, half the volunteers were designated
Guards and half were designated Prisoners. The Guards were given khaki
uniforms, wooden batons, and mirrored sunglasses — the kind that make a man
look like he has no eyes at all. The Prisoners were given nothing but a loose
muslin smock that fell just below the hip, a number sewn over the chest, a
chain bolted around one ankle, and a nylon stocking cap pressed over their
hair.
The smock had no underwear beneath it. The cap flattened
what made you look like yourself.
That was the point.

THE ARREST
They were not warned about the arrest.
On the morning of Sunday, August 14th, the Palo Alto
City Police — cooperating with Zimbardo in a way that would later raise its own
ethical questions — drove squad cars to the homes of the nine young men
designated as Prisoners. They were pulled from their beds, or from their
breakfasts, or from their front steps where they had been sitting in the
morning sun expecting nothing.
They were handcuffed. Neighbors watched from behind
curtains.
They were spread-eagled against patrol cars, their
rights read to them in a flat, procedural monotone. They were fingerprinted at
the real police station. They were blindfolded and driven to the basement of
Jordan Hall, Psychology Department, Stanford University.
The basement had been converted into a prison called
Stanford County Jail.
Three cells, each barely large enough for three people.
A solid door with a small window cut into it, threaded with wire. A supply
closet repurposed as "The Hole" — solitary confinement, a space so
small that a man could not fully extend his arms. A corridor just wide enough
for a guard to pace. Fluorescent lights that buzzed with a frequency tuned, it
seemed, not to illuminate but to irritate, to prevent the mind from finding
silence.
The smell was damp concrete and recycled air. No
windows. No clocks. No sky.
The Prisoners were stripped naked on arrival. They were
delousing powder shaken over their skin from a tin can. They were made to stand
in a line and stare at the opposite wall while a guard with mirrored sunglasses
walked slowly behind them, tapping his baton against his palm with a soft,
patient rhythm — tap, tap, tap — like a metronome counting down to something
terrible.
Then each man was handed his smock, his number, his
chain, his cap.
And the cells were locked.

THE FIRST NIGHT
Prisoner 8612 was a twenty-two-year-old from San
Francisco who had grown up near the water, who had surfed and laughed and slept
with the windows open. His real name was Douglas Korpi. His number was 8612.
By the first night, he had already begun to understand
what the number meant.
He lay on the concrete floor — there were no beds, only
blankets — and stared at the ceiling where the fluorescent tube hummed and
threw a colorless light over everything. Somewhere in the next cell, a man was
whispering. The chain on his ankle clinked every time he shifted position. The
stocking cap made his scalp itch in a way that became, over hours, almost
maddening.
The guards worked in shifts. Three on, three off. But
even the guards who were "off" often stayed, drawn by some
gravitational pull they would not fully understand until much later. They stood
in the corridor with their batons and their mirrored glasses, and they looked
at the men in the cells, and something began to move in them like a tide coming
in.
The Stanford Prison Experiment had been running for
approximately eighteen hours.
Already, it was becoming something else.

IV.
THE TRANSFORMATION
It is difficult to say precisely when the guards stopped
being students playing guards and became something more absolute.
Perhaps it was the morning of the second day, when a
guard named Dave — the one who would be nicknamed "John Wayne" by the
prisoners for his particular brand of cruel theatrics — began requiring
prisoners to recite their numbers before being allowed to use the bathroom.
Perhaps it was when another guard confiscated blankets as punishment for a
prisoner who had failed to properly make his bed — a bed made of blankets on a
concrete floor. Perhaps it was when the push-ups began: arbitrary, exhausting
push-ups demanded at any hour, for any infraction, or for no infraction at all,
simply because the baton pointed and the voice said: down.
The mirrored glasses were important. The guards wore
them religiously, even indoors, even when no prisoners were watching. The
glasses made them look inhuman — eyes replaced by silver reflections — and
this, it turned out, was not merely a costume effect. The guards reported that
behind the glasses they felt less observed, less known, less themselves. The
anonymity was not a disguise. It was an excavation. Something underneath was
being revealed.
Guard Hellmann — the one who seemed to relish the work
most, who paced the corridor with an energy that resembled excitement — began
waking prisoners in the middle of the night for arbitrary headcounts. Two in
the morning. Three. Four. Prisoners were pulled from their blankets, made to
stand in a line, made to recite their numbers. Then sent back. Then pulled out
again an hour later. Again the numbers. Again the line. Again the voice of the
guard saying: louder. I can't hear your number. Say it again.
Sleep deprivation was not in the protocol. It emerged
organically, the way cruelty often does: one small step at a time, each step
feeling almost reasonable in the moment, each step impossible to separate from
the last.
In the cells, the prisoners began to change too. But not
in the same direction.
They curled inward. They stopped making eye contact with
each other. They stopped using each other's names — only the numbers now, even
among themselves, as if the experiment had successfully colonized their
language. A prisoner who had been a pre-law student began to speak of himself
in the third person: 819 needs to use the bathroom. 819 is tired. 819 does not
feel well.
819 was no longer entirely certain who he was.

V.
THE REBELLION AND ITS CRUSHING
On the second day, the prisoners rebelled.
They pushed their beds against the cell doors and
refused to come out. They tore off their nylon caps and shouted their real
names through the wire-threaded windows. They called Zimbardo's name. They
called for the experiment to end.
The guards responded with CO2 fire extinguishers.
The cold chemical spray filled the cells with a choking
fog. The prisoners stumbled back, coughing, eyes streaming. The guards pried
the beds away from the doors. Then came the punishment: the rebels were
stripped of their mattresses, their clothing, their food privileges. The
ringleaders were placed in solitary confinement. The cell that had been a
storage closet — barely large enough to stand in — became a box of darkness and
silence in which a man could hear nothing but his own breathing and the faint
buzz of the lights he could no longer see.
Zimbardo watched all of this from the monitor room. He
watched and he did not stop it.
He had ceased, somewhere in the second day, to think of
himself as the experimenter. He had become, instead, the Superintendent of
Stanford County Jail. He attended meetings as the Superintendent. He worried
about escape attempts as the Superintendent. When a rumor spread that a large
group of ex-prisoners were planning to break in and free the captives, Zimbardo
moved the entire experiment to another building — not to protect the
participants, but to protect the jail.
He later described this as one of the most disturbing
realizations of his career: that he had been absorbed.

VI.
PRISONER 8612
On the thirty-sixth hour, Prisoner 8612 began to scream.
Not screaming in the sense of shouting, though it was
loud enough to fill the corridor and make the other prisoners press themselves
to the backs of their cells. It was the sound of a man whose mind was trying to
exit through his mouth. Uncontrolled. Cycling. He screamed and sobbed and then
went very still and then screamed again. He raked his nails against the wall.
He told the guards he was burning from the inside. He said he could not feel
his feet.
The guards brought him to Zimbardo.
Zimbardo's first instinct was not to release him. His
first instinct was to suspect that 8612 was faking — performing distress in
order to get out of the experiment. This reaction — the willingness to
interpret human suffering as a performance, as a manipulation to be thwarted —
would become one of the most damning elements of Zimbardo's later
self-examination.
Eventually, 8612 was released. He had been a prisoner
for less than two days.
He walked out of the basement of Jordan Hall into the
California sun and stood there for a while, blinking.
He did not look like a man who had just been freed. He
looked like a man who was trying to remember what freedom was.

WHAT CHRISTINA SAW
On the sixth day, Christina Maslach arrived.
She was a recent psychology PhD, a colleague of
Zimbardo's, and at that time his girlfriend. She had heard about the experiment
in the abstract — a study of prison dynamics, very interesting — but she had
not seen it. Zimbardo brought her to Jordan Hall to tour the facility with the
pride, she later recalled, of someone showing off a project they were pleased
with.
What she saw was a line of young men in muslin smocks
and stocking caps, chained at the ankle, hands on each other's shoulders, being
led to the bathroom at night. A guard walked behind them, shouting. The
fluorescent light made everything look like a photograph taken underwater.
She began to cry.
She turned to Zimbardo — the man she loved, the
distinguished professor, the careful scientist — and she said: What are you
doing to these boys?
She was the only person in six days who had come into
the basement and asked that question.
Of seventy-five researchers, graduate students, parents,
police officers, prison chaplains, and a public defender who had all passed
through the basement and seen what was happening, Christina Maslach was the
only one who named it: You are doing something wrong.
That night, she and Zimbardo fought with the intensity
of people arguing about something that matters. And the next morning, on the
sixth day of a study designed to last fourteen, Zimbardo shut the experiment
down.

VIII.
AFTER
They walked out of the basement on the morning of August
20th, 1971. Six days after they had entered. Eight days before they were
supposed to leave.
Some of them stood in the parking lot and looked at the
sky for a long time.
The guards removed their mirrored sunglasses and looked
at what they had been doing.
Zimbardo removed his Superintendent's coat and looked at
what he had allowed.
The experiment was over. The building was just a
building again — bricks and fluorescent tubes and the smell of damp concrete.
The cells were just rooms. The batons were just sticks. And the young men who
had been Prisoner 8612 and Prisoner 819 and Guard Hellmann were just students
again, standing in the California morning with everything that had happened
still burning somewhere inside them.
Philip Zimbardo later spent years trying to understand
the six days in that basement. He wrote the Lucifer Effect, a study of how good
people turn evil, and lectured about the experiment for decades. He came to see
it not just as a study of what guards and prisoners become under pressure, but
as a mirror — a demonstration that none of us are as far from the darkness as
we would like to believe.
The cells have long since been dismantled. Jordan Hall
still stands. On its exterior, in the California sun, there is nothing to mark
what happened in its basement during those six days in August 1971.
But some of the men who were there have said that they
still sometimes dream of the fluorescent hum. The chain around the ankle. The
number where the name used to be.
They wake and they are themselves again.
For a moment, they are not entirely sure.
