 How one answers this question about the relation between implicit bias and belief or other attitudes bears on the question of the accuracy of introspection of the belief or other attitude in question. On the assumption that people are unaware of the extent of their bias, or at least have no direct introspective access to their bias, that failure of introspection of bias constitutes a failure of introspection with respect to the attitude in question. On the other hand, if what is at stake is merely an association or trait-like disposition, rather than an attitude, failure of introspectibility is unsurprising and does not bear on the general question of the introspection of attitudes.
