I recently went on a work course teaching communication skills. It turned out to be mainly based on NLP, which I wasn't expecting at all. There was a lot of stuff on preferred representational systems and predicates which I couldn't really relate to my own experience at all (of myself or of others). I found it hard to imagine how I would use the techniques - I'm not sure I'd be able to concentrate on the particular words that people are using as well as the meaning of what they're saying, or at least, not easily. I'm also not really sure how reliable the theories are. Should I put in the effort to try to use the theories, or ditch them?
