"How radically our ideas have changed is indicated by the fact that most psychiatric residents no longer receive any instruction in intensive psychotherapy, and many complete their training without meeting regularly with a single patient in psychotherapy sessions. During the 1950s, any research on schizophrenia was considered unethical if it included a control group given drugs without complementary psychotherapy. By 1970, however, the situation had reversed, and it was considered unethical to have a group that received only psychotherapy and no drugs" (Gunderson, J.G., Drugs and psychosocial treatment of schizophrenia revisited, Journal of Continuing Education in Psychiatry, 1977, December, 25-40) as found in text, Blaming the Brain: The Truth About Drugs and Mental Health by Elliot S. Valenstein.
