And do you think the probability of the thing you describe (or anything analogous to it but still arising from the same intervention) is substantial? I’m not claiming that all charity should be done in such an attempt-to-be-expected-utility-maximizing way, as there may be some like, component of how donations for more local causes might do more to improve the character of the person donating, and other things like that, but I don’t see your view of “but-serendipity, and but-mosquito-nets-is-no-fun” don’t seem like compelling reasons to not look at QALYs and such. That being said, I personally haven’t made any substantial donations, so if you’ve made even fairly inefficient donations (as long as they were at least a little effective, and not e.g. counterproductive) then your donations have likely done more good than mine have.
