David Rosenhan (nonfiction)

David L. Rosenhan (/ˈroʊznən/; November 22, 1929 – February 6, 2012)[1] was an American psychologist. He is best known for the Rosenhan experiment, a study challenging the validity of psychiatry diagnoses.[2]

The study has been questioned; Rosenhan never published his data nor the book he had promised; the experiment's subjects could not be found, save two, one who turned out Rosenhan himself, and a second one, whose positive psychiatric hospital experience was discarded by Rosenhan and not included in the "study."[3][4] Kenneth J. Gergen has stated that "some people in the department called him a bullshitter.”
