I know what the placebo effect is. Sure i dont know the mechanism behind it. afaik noone really knows yet. But i find it a very interesting effect. You only have to belive you get something that helps you, it may be watter, hit on leather several thousand times and mixed with more wather, and you belive it helps, the chance is there that it indeed will help, while it has actually no effect we know of, it helped.
There is a lot of research into the placebo effect, it is called regression to the mean and healing. DUH.
If some followers of Mao's revolution felt that a page of the lttle red book helped a gun shot wounds, that is like a cheap and effective treatment.
