'Common sense' is more often than not shown to be correct in the end too. Correctness depends on the quality of our reasoning skills.Yes, but "common sense" is merely unjustifiable prejudice. It was "common sense" that blacks were less intelligent than whites. It was "common sense" that women could not do math and work in the sciences.
Without our overall more helpful than not reasoning ability, how could mankind have survived? If we could make only 'unjustified prejudices' we would be extinct.
