NLP has been with us since around 1975, and still has it's skeptics. I spoke to someone yesterday who said "There's absolutely no science behind NLP". I didn't continue the conversation, as the outcome would have not been worth the effort, and i'll likely not see that person again any time soon. It always amazes me though, how people can dismiss something based on lack of scientific evidence, but won't pay any attention to anyone who has had great results through using NLP. I've seen/facilitated hundreds of life changing breakthroughs on Master Practitioner courses, and I couldn't honestly attribute any of them to science.
