Well, psychopaths don't seem to care about morality so much. So we can at least point to morality as a particular cluster among things people care about.
That's just it; it's not clear to me that we can, on this account.
Sure, there are things within morality that some people care about and other people don't. Caring about video games is an aspect of morality, for example, and some people don't care about video games. Caring about the happiness of other people is an aspect of morality, and some people (e.g., psychopaths) don't care about that. And so on. But the things that they care about instead are also parts of morality, on this account.
But, OK, perhaps there's some kind of moral hierarchy on this accoun...
In You Provably Can't Trust Yourself, Eliezer tried to figured out why his audience didn't understand his meta-ethics sequence even after they had followed him through philosophy of language and quantum physics. Meta-ethics is my specialty, and I can't figure out what Eliezer's meta-ethical position is. And at least at this point, professionals like Robin Hanson and Toby Ord couldn't figure it out, either.
Part of the problem is that because Eliezer has gotten little value from professional philosophy, he writes about morality in a highly idiosyncratic way, using terms that would require reading hundreds of posts to understand. I might understand Eliezer's meta-ethics better if he would just cough up his positions on standard meta-ethical debates like cognitivism, motivation, the sources of normativity, moral epistemology, and so on. Nick Beckstead recently told me he thinks Eliezer's meta-ethical views are similar to those of Michael Smith, but I'm not seeing it.
If you think you can help me (and others) understand Eliezer's meta-ethical theory, please leave a comment!
Update: This comment by Richard Chappell made sense of Eliezer's meta-ethics for me.
