Linguistic means using our language. The immediate thought would be that this means the words we say, but again the NLP meaning goes way beyond that. We know, from research that Albert Mehrabian undertook in 1971, that the words we use are only 7% of our total language (so purely talking therapies are only 7% effective), 38% is the tonality of our voice, and 55% is our body language! Therefore when we use NLP to make change we make use of tonality and body language to effect change. No you don’t have to be a genius at maths to realise that by using 100% of our potential for communication is going to be far more effective than using the 7% of just our words. That’s the difference that make a difference!
