"Now a report from the United States Department of Health and Human Services has confirmed
what has long been an open secret among mental-illness researchers:
the S.S.R.I.'s are no more effective at treating depression than older classes of drugs...
The most common therapy in the first half of this century was the talking cure, popularized by Freud.
There are now hundreds of talking cures, from Jungian dreamwork to cognitive behavioral therapy.
Although each is touted as an improvement over its predecessors,
scientific tests have found that all psychotherapies are basically equal...
The psychiatrist Jerome Frank warned in his classic book ''Persuasion and Healing''
that the placebo effect might be the primary factor underlying all psychiatric remedies..
psychiatrists, psychologists and other ''scientific'' healers are really exploiting the power of human belief,
just as shamans and witch doctors do",
