> Some clustering of logically unrelated beliefs could be explained cognitively—for instance, by the hypothesis that some people tend to be good, in general, at getting to the truth (perhaps because they are intelligent, knowledgeable, etc.) So suppose that it is true both that affirmative action is just and that abortion is morally permissible. These issues are logically unrelated to each other; however, if some people are in general good at getting to the truth, then those who believe one of these propositions would be more likely to believe the other.
