The article does give an example: cultural relativism.
That is not how I read it. There's a big parenthetical aside breaking up the flow, but excising that leaves
An individualistic relativism sees the vital difference as lying in the persons making the utterance; a cultural relativism sees the difference as stemming from the respective cultures that the speakers inhabit. . . . In either case, it may be that what determines the difference in the two contexts is something “mind-dependent”—in which case it would be subjectivist relativism—but it need not be.
(Bolding added.) So, either individualistic or cultural relativisms can be subjectivist. That leaves the possibility, in principle, that either could be non-subjectivist, but the article gives no example of someone actually staking out such a position.
You continue:
Its objective in that it doesn't depend on the mind of the individual, but it's still relative to something: the culture you are in.
I think that cultural relativism is mind-dependent in the sense that the article uses the term.
ok, location relativism then. It's doesn't depend on your what's going on inside your head, but it's still relative.
Less Wrong is extremely intimidating to newcomers and as pointed out by Academian something that would help is a document in FAQ form intended for newcomers. Later we can decide how to best deliver that document to new Less Wrongers, but for now we can edit the existing (narrow) FAQ to make the site less scary and the standards more evident.
Go ahead and make bold edits to the FAQ wiki page or use this post to discuss possible FAQs and answers in agonizing detail.
