For background, Andy Bradbury is devastatingly accurate. I spent some years reading and applying NLP techniques, and, indeed, the techniques "worked." I was very aware of what Bradbury points out, over and over, that Bandler and Grinder made a crucial distinction between actual practices and effectiveness and the conceptual models that were presented by "master therapists," such as Perls, Satir, and Erikson, and this would obviously apply to NLP as an approach as well as anything else. My own experience is, of course, anecdotal. But the results were little short of astonishing. That does not establish NLP as a "science," but as more of an "art." The articles on NLP should reflect this understanding, based on reliable sources, and care should be taken about avoiding defining NLP so as to set up straw man arguments.
