(I apologize for not responding sooner; I've just realized I'm in one of my periodic bouts of anhedonia and social procrastination.)
My short absence seems to have given enough time to get a selection of votes in, and since I'm just about to actually apply the results of this discussion to my fiction, it's time to analyze the results.
I'm ruling out 'rational self-interest' as already being used to refer to a closely-related but not-quite-identical concept, so that I can have my characters discuss the differences.
First word:
Aka, coming up with a better term for applying LW-style rationality techniques to 'rational self-interest'.
Aka, in parallel with the current movement of 'Effective Altruism', which seeks the best available ways to fulfill one's values, when those values focus roughly on improving the well-being and reducing the suffering of people in general, seeking the best available ways to fulfill one's values, when those values focus roughly on improving the well-being and reducing the suffering of oneself.
(I find that I may have use for this term both in reality and in my NaNoWriMo attempt.)
