In this blog I gave my opinion about the absurdity of the assumption that all people follow the same specific pattern of movements with their eyes so you can access to other people internal mental processes. I also gave my opinion about anyone who teaches that, in my point of view, he does not understand the principles of NLP and thus discredited him as a trainer.
But then, one of the co-creators arrives to
If I’ve been able to see it by myself (I am an apprentice compared with the 35 years of Grinder giving courses), why he (and almost all books in NLP) are still repeating the same? Well, my explanation is simple: because it sells. Just the idea that they can access the most intimate thoughts of a person simply by observing that with their eyes is a powerful lure for many.
Of course, that they forget to explain that people run complex strategies inside they brains before giving an answer or just before thinking about who they are. Someone who is thinking, deliberating, considering, or constructing or any of the 7 different internal dialogues that my friend Eric Robbie described, is carrying out sophisticated mental processes that can not be reduced to a simple single eye movement.
But this makes it complex. And the complexity does not sell. It has to be fast and efficient. And Grinder knows. Well, I think that's the explanation. Because another explanation would leave him in a strange position.
Eye access cues are very useful to understand the different patterns of a person. That is, when you find a repeatability before certain stimuli that allow you to generalize enough to reduce the margin of error in predicting their future eye movements.
Also, do not forget that the accesses are not the only access cues. Why just to have information restricted to the eyes if you can get information around the body?
