Hump is, in one real sense, generally correct about the relative merit of going balls-deep into topics such as these: a little knowledge is a dangerous thing after all. But what I was referring to specifically is NLP = NeuroLinguistic Programming — which I tend to regard as a Psionic discipline, but that would likely raise many objections from the general direction of the establishment. It’s usually lumped in with hypnosis, with which it has some overlap.
