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?
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.
