I think that what you said, Jim, (I quote): "I think that a person that internalizes everything and doesn't get things off of their chest or communicate about things on a daily basis, will experience a breakdown a lot quicker than one that does. Here, intelligence doesn't really play a part." is true, but intelligence does play a part here - not the one you think of but "emotional intelligence" for sure. So I guess, if you combine this observation with (let me just call it this way) your "tradeoff" theory (you know the one which states that a genius would be excellent in certain aspects of life and totally not so in others) it would actually (maybe) make sense to say that while being very intelligent (in the common sense of the word "intelligent") a genius tends to being a failure in the "emotional intelligence" sector.
