Both the Milgram and Rosenhan experiments involved deception and ethical concerns. Milgram's obedience study examined the extent to which people would obey authority figures, while Rosenhan's study focused on the ability of mental health professionals to accurately diagnose mental illness. Both experiments raised questions about the ethical treatment of participants and the responsibilities of researchers.

The pseudo-patients in David Rosenhan's study were diagnosed with psychiatric disorders, admitted to various mental hospitals, and discharged with a diagnosis of schizophrenia in remission. Their experiences highlighted flaws in psychiatric diagnosis and treatment, as well as the challenges of distinguishing between sanity and insanity in a hospital setting.
