One method intended to help, "facilitated communication," is based on the idea that a sensitive facilitator will hold the hand of a patient over a kind of Ouija board. She will then help the patient respond to questions by sensing his intention and helping guide his hand to spell out answers. Rigorous studies have shown that the spelled-out answers come from the unconscious (or, worse, the conscious) mind of the facilitator. Nonetheless, the practice is still in use, and I know parents who are utterly convinced that it is valid and useful. Frankly, something important did happen when facilitated communication was introduced to my patients: They improved, they brightened, they became more social and more interactive, and they seemed, somehow, happier, even though facilitated communication didn't actually translate their thoughts into words. I'll come back to "why" in a minute.
