Considering the holiday weekend, I think Mene Gene makes a pretty good argument here.
From a market-based perspective, believing in God would appear to make good economic sense. Believing in God comes with a substantial but not onerous cost (occasionally attending church, no worshiping false gods, keep the killing and stealing and adultery under control) and it has a big payoff in the end–a blissful eternal afterlife. Even if its a million-to-one that God exists, eternity is a long time. You’ve got implied odds out the wazoo.
I’ve seen David Sklansky discuss the subject of religion and it seems at times as if he attempts to pose questions to “the believers” as a way of setting them up to attack the logic of their faith but I think Gene may have hit on an argument that even the logical, mathematically-minded David Sklansky might have a difficult time with. 🙂
