For posterity, we discussed in-person, and both (afaict) took the following to be clear predictive disagreements between the (paradigmatic) naturalist realists and anti-realists (condensed for brevity here, to the point of really being more of a mnemonic device):
Realists claim that:
(No Special Semantics): Our use of “right” and “wrong” are picking up, respectively, on what would be appropriately called the rightness and wrongness features in the world.
(Non-subjectivism/non-relativism): These features are largely independent of any particular homo sapiens attitudes and very stable over time.
(Still Learning): We collectively haven’t fully learned these features yet – the sparsity of the world does support and can guide further refinement of our collective usage of moral terms should we collectively wish to generalize better at identifying the presence of said features. This is the claim that leads to claims of there being a “moral attractor.”
Anti-realists may or may not disagree with (1) depending on how they cash out their semantics, but they almost certainly disagree with something like (2) and (3) (at least in their meta-ethical moments).
