In not so serious conditions or in people who trend towards hypocondria the surgery will lend a placibo affect. This will cause the patient to testify that they have been cured.
In serious conditions the patient dies.
It's nothign but a Goddamed sham and the assholes who provide these types of side show theatrics should be arrested and tortured.
It does not even have to be placebo effect. Assuming the patient really did get better and is not just lying or crazy, it's just ordinary statistics.
Suppose ten people diagnosed with cancer go to this "psychic surgeon" to be treated. Two get better, two stay the same, and the rest die. The two who got better go on tv and the internet and publicity tours. It's a miracle, right?
Well, there is the little fact that 80% of the patients did not get better, not exactly a good track record for a miracle cure. Dead people don't make very compelling infomercials. (They just did not have enough faith, I know.) The two who stayed the same won't go on tv either because they will look like idiots.
And many people with cancer get better. It's called remission. A lot of people with cancer try all kinds of things to get better. Who knows if it was the vist to the psychic or quitting smoking or the vitamins and diet the person had been using for the previous six months? Or the chemo and radiation that the patient never told the press about?
Without a controlled test of some kind (ie. at least look at ten or a hundred people with cancer who never go near the miracle doctor and see how many get better) there is no way to isolate the effect of the psychic surgery.
The real test is, can the miracle person do something that medicine can't do, and that never happens all by itself. Like, say, remove Down's syndrome. Or heal an amputee.
