I would distinguish between the general form and the idealized general form. One way to generalize Pascal's wager for belief B, is to compare the expected utilities of believing B and believing one contradictory Belief D in the conditions that B is true and that D is true. This is wrong no matter what belief B you apply it to.
It has been claimed on this site that the fundamental question of rationality is "What do you believe, and why do you believe it?".
A good question it is, but I claim there is another of equal importance. I ask you, Less Wrong...
What are you doing?
And why are you doing it?
