The Rosenhan experiment was conducted to evaluate the validity and reliability of psychiatric diagnosis. The experimenters feigned hallucinations to enter psychiatric hospitals and acted normally afterward.
The David Rosenhan study supported the claim that diagnosis of mental illnesses is often influenced by context and subjective evaluations.
Psychiatrists examined Rosenhan and others. They diagnosed them as mentally ill. As a result, Rosenhan concluded that it is not possible to distinguish between the sane and the insane in psychiatric hospitals.
