Many times (starting with the title) the phrasing chosen suggests that you are attacking the basic decision-theoretic principle that one should the take the action with the highest expected utility (or give to the charity with the highest expected marginal value resulting from the donation). But you’re not attacking this; you’re attacking a way to incorrectly calculate expected utility by using only information that can be easily quantified and leaving out information that’s harder to quantify.
Agree.
