the only compelling argument I've heard against Pascal's Wager is that you can't/shouldn't believe something just because it is convenient to do so

As I understand it, that's because our universe has provided no evidence that belief alters reality; but it does seem to suggest that the optimum strategy is relentless pursuit of truth. However, if we had good reason to think otherwise (I don't think this article counts), I see no reason why one shouldn't alter their beliefs to their benefit, apart from aesthetics.

Whether or not this is even possible is unclear to me; but my intuition is that I could intentionally update to false beliefs, contrary to what seems to be the consensus here.
