Hi NeverFly. Yeah, I remember this study. It's very appropriate - in several ways - that you bring it up here. There's a huge difference between simply thinking positive and having a good attitude than reshaping physical reality by magical mental powers aided by a cosmic overlord.
The interest folks have in POA is very much a parallel to religion, and thus modern people - even those with enough sense to know better - are praying for something they want even at this moment.
All of this stems from a fundamental misunderstanding that ideas are merely ideas. They have no physical correspondence. This is essentially the same ideology that leads people to believe in magic, spoon-bending and levitation. Holy rollers jumping up and down shouting "Praise Jesus!" just because some actor gets up out of a wheelchair is one of the classic examples. The profound alteration of their rational sense of reality can be seen by the tears in their eyes, the jumping and screaming, or worse, the ones who practically induce seizures in themselves with their extravagant fits.
I don't think any of this existed prior to the American fundamentalist movement. Before then religious people went by a reverential protocol that included silent prayer and silence in church, except for answering prayers or chants, or choral music, which was straight-laced and nothing likely to induce fits.
Maybe in modern times more nuts are simply out of the closet and they've simply sought refuge in religion because it's so nutty too and protective (as it is protected) and malleable.
Thanks for the links. It's funny how people hear facts like this and still dismiss them. POA could probably better be called POD - power of denial.
