I think you make an important distinction, but people sometimes act like gaining understanding will result in a long-term reduction in some warm fuzzies for them. They sometimes explicitly tell me they think this will happen. While I think people may underestimate the net warm fuzzies resulting from learning (i.e. they are biased), I'm confident that they are sometimes correct. The difficult question is deciding what we should do about this.

Don't get me wrong, I'm still very committed to epistemic rationality and will try to sell people on its many virtues/benefits.
