To paraphrase, There are more things on heaven and earth than fit into your philosophy, Horatio. Your wishing it not to work has no effect on reality, except yours.
The opposite could also apply, though. There could be things fit into Horatio’s philosophy that don’t exist on heaven or earth, and wishing something to work has just as much effect on reality.
Personally, my opinion on NAET (as well as homeopathy and suchlike) is that I have no problem with the notion in and of itself. If people want to go get NAET treatment, that’s their business. I see no reason why NAET couldn’t be used alongside modern medicine; it doesn’t involve anything that is at all likely to actively cause harm, and it may just provide a helpful morale boost or placebo effect. The problem is when somebody uses lies and scare tactics to try to scare people away from modern medicine entirely and to make them dependent on NAET. It is as proven as anything can possibly be that modern medicine can successfully mitigate or end a huge number of ailments, as well as prevent quite a few. NAET, on the other hand, has yet to be shown to do anything. . .but is claimed by many of its supporters to be able to do just about everything. By using lies and fear, some supporters of NAET try to panic people into choosing NAET exclusively (as opposed to letting them make an educated choice) and to delay getting proven treatments. And that can cause harm.
And I just want to point out that every time I read your user-name, I hear Freddie Mercury’s voice singing it. This point has nothing to do with the topic, and is meant as neither support nor criticism. I’m just mentioning it.
