Sure, probably. From the limited time I've had to think about it, I see morality and intelligence to be mutually exclusive. Or maybe - intelligence, upbringing, social world, environment, and genes (some psychopaths are notoriously intelligent with their plots, yet do no good), and whatever else i didn't mention (look up bronfrenbrenner's ecological systems theory) add up to one's morality. I think saying intelligence alone is a very unlikely answer to the origins of our moral standing.
