How about James Henry Leuba's term: psychotherapic cult for the mind-cure movement or New Thought. I think that mind-cure comes under the more general heading of psychoceramics, which field of study encompasseth many. The lay-term for this multitude is crank or kook. Pseudoscientific crackpottery is alive and well mainly thanks to the easy access of the Web.

Ceci n'est pas un seing.
