It seems almost as if we are afforded a certain amount of "intelligence" and it is split between "emotional" and "cognitive". Those who exhibit high ability in one seem to suffer from not enough of the other.
I really like these sorts of 'zoom out' comments, because they tend to show the similarity between disparate systems and the cross-domain value inherant in systems thinking. (Then again, HN is probably a bit of an echo-chamber for this!)
