The *business* of psychiatry/psychology is more often than not operated by psychos and while some of what they do may be art, it certainly is *not* science. Why anyone pays attention to what these contemptible industries has to say, I don't know. Why professional con-men are still allowed to testify in court remains beyond me. What else can anyone say about a snake-oil industry founded on the ravings of a 19th century cokehead?
If it can't be stated in one sentence, it isn't understood.
Most psychiatric organizations lost all right to claim themsleves to be "credible" long ago. Most have been infiltrated with activists like the gay activists did to the American Psychiatric Association when they caused general disruption of their conventions before the APA caved into their agenda.
Even the pro-homosexual scientist Levay stated that it was clearly gay activism that caused the APA to "normalize" homosexuality in 1973.
