  Sinnott-Armstrong claims that results from empirical psychology show that most of our moral beliefs are false, because they have been formed by an unreliable process (2006, 353). The unreliable process is basing them on intuitions that are systematically distorted by morally irrelevant factors, such as order or wording. Sinnott-Armstrong doesn’t deny that some moral intuitions can justify moral beliefs. But given that the default justification provided by so many of them is undermined by distorting factors, we need to check that some moral intuition is not one of the undermined ones before we can take it to provide justification. But then, he argues, the intuitions that do provide justification do so only inferentially. Since moral intuitions either don’t provide justification at all, or do so only inferentially, there is no non-inferential justification for our moral beliefs and intuitionism is false.
