Rosenhan experiment

The Rosenhan experiment was a famous experiment done in order to determine the validity of psychiatric diagnosis, conducted by psychologist David Rosenhan, a Stanford University professor, and published by the journal Science in 1973 under the title "On being sane in insane places". The study is considered an important and influential criticism of psychiatric diagnosis. It was while listening to one of R. D. Laing's lectures that Rosenhan wondered if there was a way in which the reliability of psychiatric diagnoses could be tested experimentally.
