Some personality traits may be conducive to “natural” rationality. High scores on the Narcissistic Personality Inventory for example may indicate ego-preserving tendencies that make greater levels of rationality more difficult to obtain. I’d imagine that natural levels of introversion would also help, and I say that as someone who usually maxes out the extroversion scale on these kinds of tests.
