:::: I agree. It will be better explained later and I'm glad you see nothing wrong with the idea of hypothesis. I think the word is much more accurate than that of 'Theory' which implies a greater range of evidence and greater likelihood of truth. NLP does not cite evidence, nor does NLP even generally claim their postulates are true. They are simply assumptions made for a practical ground for taking action. Perhaps the best way to include this, would be to simply keep it the way  approved, "'Neuro-linguistic programming'(NLP) is a set of techniques, postulates and beliefs that adherents use primarily as an approach to psychotherapy, healing, communication and personal development, and at a #link to where the concept is explained later in detail.
