Ethically, I think they are limited to non-threatening diseases that have no effective treatment.

If voluntary, controllable mind states could contribute to well being, I think that would be readily apparent, and we would all use mind states to ameliorate disease. I have read other studies that show that the patient's attitude and degree of optimism or pessimism has no impact on outcome of serious diseases such as cancer. It is widely believed that the patient should "fight" cancer, or that a brave or positive attitude will increase the likelihood of survival. The studies I saw tested this hypothesis. The researchers assumed the prognosis would be improved with a positive outlook but they found no evidence for that. The results were a surprise and a disappointment to the researchers, which makes me think the results were real. It increases credibility. The is not the result of wishful thinking. The placebo studies involved a pill, but also a kind word from a doctor or nurse. The hypothesis was it was the latter which had the effect. The control was no pill and a simple statement from the doctor along the lines of: "Go home and call us if doesn't go away in a week." I suppose even that would be reassuring. I would think, "it can't be serious if they are sending me home empty-handed." - Jed
