We develop an argument for a novel version of moral intuitionism centered on the claim that moral intuitions are trustworthy. Our argument employs an epistemic principle that we call the Trustworthiness Criterion, a distinctive feature of which is its emphasis on oft-neglected social dimensions of cognitive states, including non-doxastic attitudes such as intuition. Thus our argument is not that moral intuitions are trustworthy because they are regress-stoppers, or because they are innocent until proven guilty, or because denying their epistemic contribution (...) would be self-defeating, or because they are presupposed in rational inference, or because they are analogous to perceptions, or because they are based on understanding—individualistic claims that have elsewhere been used (controversially) in defense of the thesis that moral intuitions are in good epistemic standing. Rather, our argument appeals to the idea that moral intuitions are trustworthy because they are the outputs of a cognitive practice, which has epistemically-fecund social elements, that is in good working order.
