It might, or it might not. This is one study. It is not necessarily definitive.
One article on the Internet does not mean that what is reported is True. Not accepting the claims of an article is not the same as "complete rejection". Have you seen anything about it besides the one article? Why is that sufficient evidence? Why shouldn't an extraordinary claim be questioned? Why should it be accepted at face value?
You wish to believe it. Others do not see it as proven.
I am not asserting one study is definitive, only that one study provides a large amount of evidence that must be considered.
I think you are confusing the claim and the evidence. The claim is that Orthodox prayer and crossing has power, and the study is the evidence. However, there is not simply "one article" on it. There are already a few sites on it in English, and there are likely more in Russian, but one of the Russian-speakers would have to check that out and confirm it. The study being conducted in Russian, I am not sure there is going to be too much on it in English for some time.
I am naturally skeptical of these things too, don't assume I simply "want to believe it" and that is my proof. However, after some time, I still have seen no arguements (credible or even otherwise) that challenege the validity of this research. With the amount of buzz something like this generates, one would expect to see many such arguements, as is the norm with similar research/experiments. I have seen none. I am quite willing to accept that this maybe false; I have no problem in saying that it is (and that I am) wrong. I only ask for some type of evidence first.
