Misdiagnoses
THE GREAT PRETENDER WHO EXPOSED OUR DEPTHS OF PREJUDICE
In 1973, Stanford psychologist David Rosenhan ran one of the boldest experiments in history.
He sent 8 healthy people into psychiatric hospitals to see if doctors could tell they were sane.
Not one was detected…
What he found exposed psychiatry’s darkest secret:
Rosenhan wanted to know:
“Could psychiatrists tell if someone was actually insane?”
To find out, he did something unthinkable…
He recruited 8 healthy individuals willing to get themselves committed to a mental hospital:
• 1 painter
• 1 housewife
• 1 pediatrician
• 1 psychiatrist
• 3 psychologists
• Rosenhan himself
Their goal was simple:
Infiltrate psychiatric hospitals with a single fake symptom:
• Report hearing a voice saying “empty” or “hollow”
• Try to convince staff you’re sane
• Show no other symptoms
• Take detailed notes
Rosenhan sent them across hospitals in 5 different US states.
During admission interviews, each person told their real life story with complete honesty. Real names, real jobs, real families.
The only lie was that single voice saying “empty.”
What happened next shocked even Rosenhan. . .
Every single person was admitted immediately.
The diagnoses were shocking:
• 7 diagnosed with schizophrenia
• 1 diagnosed with manic-depressive psychosis
Every single professional was fooled.
But getting admitted was only the beginning of this nightmare…
Once inside, the pseudopatients behaved completely normal.
They followed rules, made friends, and took notes about their experience.
Yet doctors saw everything through the lens of mental illness.
Normal behaviors became symptoms:
• Writing notes? “Compulsive writing behavior”
• Acting friendly? “Inappropriate affect”
• Keeping tidy? “Obsessive tendencies”
Once labeled insane, everything reaffirmed the diagnosis.
Here’s the fascinating part:
35 real psychiatric patients saw through the act immediately, saying things like:
“You’re not crazy, you’re a journalist checking on the hospital.”
The patients knew, but the professionals had no clue…
Life inside was also dehumanizing.
Questions went ignored.
Staff avoided eye contact.
Personal boundaries were violated.
Even normal activities like journaling were pathologized.
And escaping proved nearly impossible.
The average stay lasted 19 days.
The shortest was 7 days.
The longest? 52 days.
The only path to release was admitting they were mentally ill and agreeing to take powerful antipsychotic medications!
The pseudopatients secretly pocketed every pill, but the numbers were disturbing:
• 2,100 total pills prescribed
• All were completely unnecessary
• Some could have caused permanent damage
Their discharge diagnosis? “Schizophrenia in remission.”
When Rosenhan published these findings in Science magazine, psychiatry erupted.
In defiance, one hospital issued a bold challenge:
“Send us your fake patients. We’ll catch them.”
Rosenhan accepted.
Over the next three months, the hospital confidently identified 41 suspected imposters among their 193 new admissions.
The twist?
Rosenhan didn’t send any.
Their paranoia about being fooled created imposters everywhere they looked.
Rosenhan’s study changed psychiatry forever.
It led to:
• Modern DSM criteria
• Deinstitutionalization
• Major diagnostic reforms
• The patient rights movement
• Closure of many psychiatric asylums
So what do you think? Can psychiatrists really tell if someone is insane?
