I wasn't having a go at *you* for being unscientific. It's the whole basis of NLP that doesn't have a scientific basis. You say you are interested to try and figure out why it works, but all the evidence that has been properly collected seems to indicate that it *doesn't* work. It's a theory that has caught the public attention because it has an intuitive appeal and because its proponents have marketed it really well especially in a business environment. But there is little evidence that it has any sort of truth.
