No religious beliefs
I have heard about these prayer studies but I do not consider them scientific.
There is no way to know bout the effects of prayer. One can only believe.
Nor I. I was trying to suggest how they might be made more scientifically robust.
There's something you have said that I need to acknowledge. I'll put it a slightly different way. How do you investigate a being that is (supposedly) so much more powerful than you? Looking at science, we (humans) always have more power than the subject of the investigation (we can put it on microscope slide or whatever), or at the least, it will sit still to be investigated. Not so God. If God doesn't want to be found he won't be.
Investigating prayer is a good example. God would know that he was part of an investigation and could refuse to cooperate. Double blind studies can't apply to God, by definition.
The big problem is that this highly logical train of thought leads to lots of problems. But enough for now.
I may start a thread on this, once I rest a bit from this one.
