I agree with Jahed. I consider such experiments are important as these show that at least some religious experiences and claims are scientifically testable. The prestigious Mayo Clinic also did similar clinical study on the healing powers of intercessory prayer but the Mayo researchers also could not find any evidence that such prayer affected the health of the study subjects. The study at the Mayo Clinic was conducted between July 1997 and October 1999. Results were published in the Mayo Clinic Proceedings. The statement said that...:
"Researches found that intercessory prayer had no significant effect on a patient’s medical outcome after hospitalization. We found that prayer had no effect on rates of death, heart attacks, strokes and hospitalizations."
Yeap...Prayer does not work; if there is anything really "works" it is "Placebo effect" (http://skepdic.com/placebo.html ). In many cases, fake dummy pills, Huzur Saaidabadi's blessing, Sai baba's bibhuti or astrological stone seem to work too in minor diseases because of patient’s psychological attachment, not because of any miracle. Bringing "haves” and “have nots" in scientific study is perhaps misleading. Science in this case is, and should always be miserably neutral, scientific truth does not care about majority peoples’ sentiment. I am, by the way, not denying that people derive enormous comfort from prayer etc, but problem is most of the realistic studies connecting prayer and healing is scientifically showed otherwise. Those faith healers, fakirs, shadus and other godmen who play with common peoples’ faith are nothing but cheater. Let's accept the fact.
