Narz, I don't believe in this stuff, and am an ardent athiest, however the attitude with which you made that post is really quite aggressive. It comes across as not asking to find out other people's opinions in an open and honest way, but first saying "This is what I believe about your beliefs. Now try to tell me different."
It seems to me that you're not looking for answers or opinions, you're looking for a fight.
Disregarding that, here is some stuff that Pavlina's written abuot beliefs. I'd imagine he applies the same criteria for choosing spiritual beliefs. This seems to be the best way I can think of to consciously choose beliefs.
