Thanks for the link to the Overcoming Bias post. I read that and it clarified some things for me. If I had known about that post, above I would have just linked to it when I wrote that the fallacy behind Pascal's wager is probably actually unclear, minor or controversial.
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?
