NLP has at its very foundations and its core the need for Modelling Projects. These projects were designed for its master practitioners to give something back to the world of NLP and further develop the field (at least that is what a properly trained Master of NLP has taken part in). Very similar to other scientific models these are theories that are developed by conducting interviews and detailed NLP assessments and analysis with people whom you want to model a behaviour or pattern from.
It is believed in NLP if you can model a skill or trait in one person. And that someone else is looking to work on that skill or trait. Then you can teach the person working on it how the other person does the thing. by teaching them to not just think how the other person thinks and do what they do but also how they feel, stand etc embodying the physiology as well as pschology, you not only train them you instil the neurolinguistic program into them. An example would be: how do you teach a nervous speaker to deliver great speeches in public? You model the behaviour, language patterns, physiology and programming of great public speakers and find out what it is that sets them apart from others. Then turn this into a trainable model for your nervous speaker. You reprogram them into thinking, behaving, talking, acting and feeling like the great speakers and away they go.
The problem in NLP is that there are so many of these models out in the market that has become flooded by training programs and their creators have made money out of them that the results of these models have not been quantifiable or scientifically proven. In fact, some. Like the one you may have heard of that went round the schooling systems in the 90’s that; you can tell if a student is lying by where their eyes move when they are talking to you or answering questions. This has since been widely debunked, proven wrong or as in this case they are not always true all of the time for all people and baselining and calibration is required.
Another problem with the field is that too many people become NLP practitioners without developing their own models but instead blindly rely on those as gospel that has come before them that have been developed by others.
And those of us whose trainers insist we do carry out a full modelling project far too often go into the field, publish their results and setup practising and teaching these models without testing them out thoroughly in a quantifiable scientific way. Thankfully though some of our master NLP trainers, like mine, are more demanding of their students than that.
