How speciifically is NLP pretty temporary in which of its effects?
NLP is still around and still has people interested in it and practicing it. It was started years ago. That's pretty un-temporary if you asked me. It continues to fascinate. That's one effect.
I started to learn NLP while in college, around 1993, I think. It's 2004. Still has had an effect on me. I am still talking about it. The stuff that happened at the month long training *still* has me talking about it and still informs my behavior in some way. I think a decade is a fairly long time, don't you?
The mind is alive and is always changing. There are information structures that are fairly solid. It is not impossible to influence these structures in a significant way that will alter their functioning over time.
Think of our solar system. Remove or add a planet. It affects the whole system. Alter the orbit of a planet or a moon, alters the whole thing.
The trick is, where and how do you make the change that will have the desired effect throughout time.
Here is one example: once I learned the distinction regarding eye movements and sensory modalities, I could *not* look at people's eye movements the same way. Still can't. That was a permanent change.
And here is the real clincher regarding your question: your question has deleted the actor. That is, NLP is not a thing in an of itself. People do NLP. So, my question is, which person practicing what they called NLP produced a temporary effect?
Which person practicing an NLP technique can have a positive long term effect how?
That person could be you or me or the garbage man. It just depends on how the person does it and with whom. Each client is different. Each practitioner is different. And when you get any two people to interact, the nature of their interaction will be unique.
In short, you *can* produce long term change with NLP. Of course you can. You can create long term change in someone with a hatchet. The question is, what change do you feel is worthwhile and whats the best way to create it for you or for the client?
