In 1972, American psychologist David Rosenhan published the Rosenhan Experiment, a study analyzing the validity of psychiatric diagnoses. The study arranged for eight participants with no history of mental illness to attempt admission into psychiatric hospitals. The individuals volunteering for the study were a housewife, a graduate student, two physicians, a psychiatrist, two psychologists, and an artist. All were admitted to psychiatric hospitals, each receiving a diagnosis of schizophrenia or bipolar disorder, and all were treated with medications. All were discharged between 7 and 52 days. The study concluded that individuals with no presence of mental disorders could not be distinguished from those suffering mental illness.
