I’ve come to think that evidential cooperation in large worlds and, in different ways, preference utilitarianism pushes even antirealists toward relatively specific moral compromises that require an impartial empirical investigation to determine. (That may not apply to various antirealists that have rather easy-to-realize moral goals or one’s that others can’t help a lot with. Say, protecting your child from some dangers or being very happy. But it does to my drive to reduce suffering.)
