Gullibility feels similar. Ideally we'd have highly intelligent & rational people be more gullible, and less intelligent & rational people be less gullible.

Consider parallels to the "openness" personality trait--for the intelligent and conscientious, high openness seems good (they're able to rapidly adapt to changing conditions, in a healthy way because of their intelligence and conscientiousness) but for those lacking those traits, high openness seems bad (they'll fall into pits because they wander without being able to see what to avoid).
