I do like the idea of being able to construct an experiment to test naturalism. I think it’s mistaken in that I doubt there are any facts about what is right and wrong to be discovered, by observing the world or otherwise, but currently I and anyone else who wants to talk about metaethics is forced to rely primarily on argumentation. Being able to run an experiment using minds different from our own seems quite compelling to testing a variety of metaethical hypotheses.
