I wonder how I can tell the difference between sanity and insanity in people.
Rosenhan thought of an experiment that would show how good mental hospitals are at telling the difference between sanity and insanity
I feel fine!
Rosenhan organised an experiment that would have 8 pseudopatients fake a mental illness (schizophrenia) and get sent to 12 different mental illnesses
The pseudopatients complained to a doctor/psychologist about hearing voices that keep repeating the words "empty", "hollow and "thud". They then got diagnosed with schizophrenia
You're not really sick are you?
Once the pseudopatients were admitted to a hospital, they stopped pretending to have symptoms and acted "normal" to see if the medical staff would notice
But they never did! The medical staff kept treating the pseudopatients the same way even after they stopped showing symptoms of a mental illness.
However, the other real patients were harder to fool: 35 out of 118 patients said they were suspicious about whether the pseudopatients faked a symptom and then acted normal in the hospital. They believed they were journalists or checking up on the hospital
