So, if I said, "X act is wrong because..." (a logically arrived at conclusion) to someone with superior cognitive abilities, they would agree with me. However, if they disagreed (also a logical conclusion), it would mean that I was simply unable to see all aspects of the situation.
How would I tell that the person has superior abilities in that regard than I do?
