Reflective equilibrium has been criticized for various reasons ever since the publication of Rawls’ A Theory of Justice. Recent empirical research into moral decision-making poses new challenges to RE because it questions the reliability of moral intuitions. This research might discredit moral intuitionism in general and RE in particular insofar as it ascribes epistemic value to moral intuitions. These findings suggest, for instance, that moral intuitions vary with cultural background, gender or framing. If it could be shown that all or (...) certain kinds of moral intuitions are unreliable, this would diminish the plausibility of the claim that they provide good reasons to believe in the truth of their content, especially given the growing evidence that professional philosophers are just as biased and susceptible to distorting factors as lay people. In this paper I critically discuss three recent defenses of RE against this unreliable intuitions objection. Two of these defenses argue that the UIO misses its target, because RE does not depend on intuitions, or because the relevant considered judgments in RE are not intuitions. The third defense grants that RE depends on intuitions and that some Rawlsian considered judgments are intuitions. But it argues that the notion of considered judgments can be revised, and that wide reflective equilibrium has the means to adopt the criticism because it can use information about unreliable intuitions and exclude those from further consideration. I argue that the first two defenses do not succeed. The third defense is the most promising one. However, I argue that this defense also fails. In this defense, RE is not a distinctive moral epistemic theory: different versions of RE would be conceivable, all of which are deeply problematic. I conclude with a discussion of the broader philosophical implications of the UIO, specifically whether or not accepting the UIO would warrant skepticism regarding moral knowledge. (shrink)
