Sane or Insane?

Consider:

In January 1973, Science published an article called ‘On being sane in insane places’. The author, psychologist David Rosenhan, described how he and seven other healthy people had reported themselves to a dozen psychiatric hospitals, claiming to hear voices uttering odd words such as ‘thud’ or ‘hollow’ — a symptom never reported in the clinical literature. Each person was diagnosed with either schizophrenia or manic-depressive psychosis, and admitted; once inside, they stopped the performance. They were released after an average of 19 days with diagnoses of ‘schizophrenia in remission’ (D. L. Rosenhan Science 179, 250–258; 1973).

One research and teaching hospital, hearing about the study, declared that its own staff could never be so deceived. It challenged Rosenhan to send it pseudopatients. He agreed, but never did. Nonetheless, the hospital claimed to have identified 41 of them.
