 One reason disagreement is a useful measure of objectivity is that the impossibility of faultless disagreement is taken to be characteristic of questions concerning objective matters of fact. That is, while we might concede the possibility of faultless disagreements about matters concerning the deliciousness of foods or the merits of a sports team, when we disagree over moral issues, we think that there is a correct answer and that therefore at least one disputant is getting things wrong (for a discussion of the analogy between food and morality, see Loeb 2003). To the extent that people judge a disagreement to be faultless, we might think that they are evincing a kind of anti-realism about the issue under dispute. This is yet another way disagreement can bear on the realism/antirealism debate. Can experimental evidence involving disagreement tell us anything about the semantics of moral language?
