"I am constantly amazed by how many patients who come to see me believe or want to believe that their difficulties are biologic and can be relieved by a pill. This is despite the fact that modern psychiatry has yet to convincingly prove the genetic/biologic cause of any single mental illness. However, this does not stop psychiatry from making essentially unproven claims that depression, bipolar illness, anxiety disorders, alcoholism and a host of other disorders are in fact primarily biologic and probably genetic in origin, and that it is only a matter of time until all this is proven. This kind of faith in science and progress is staggering, not to mention naive and perhaps delusional. (Against Biologic Psychiatry, Dr. David Kaiser, Psychologist, Psychiatric Times, December, Dec. 1996, Vol. XIII, Issue 12)
"The ideology of bioreductionist psychiatry is that depression, schizophrenia, and other illnesses are biomedically distinct and genetically driven. Decades of fishing for supporting data have yielded nothing of substance, however" (Pseudoscience in Biological Psychiatry, Colin A. Ross, M.D., & Alvin Pam, Ph.D., 1995, p. 140).
