Are you familiar with prospect theory?

No, but I will surely read up on that now.

You seem to be describing what you (an imperfectly rational agent) would choose, simply using "PVG" to label the stuff that makes you choose what you actually choose, and you end up taking probability into consideration in a way similar to prospect theory.

Absolutely. In fact I can see how a theist will simply say, "it is my PVG to believe in God, therefore It is rational for me to do so."

I do not have a response to that. I will need to learn more before I can work this out in my head. Thank you for the insightful comments.
