Agreed. If you're really smart and a prick, well, then you're just a really smart prick. Intelligence and emotional mastery are divorced from one another.
Intelligence and creativity are also divorced from one another. Unlike Newton, da Vinci, Einstein, most intelligent people aren't creative in the cultural sense. Their creativity is rather directed towards fitting in more effectively and being more social than the norm. Which in extreme cases looks like multiple personality disorder, i.e. changing one's responses according to context, the opposite of integrity, including the intellectual integrity required to create new stuff.
> most intelligent people aren't creative in the cultural sense
I would beg to differ. Most of the people I know of high intelligence seem to be a jack-of-all-trades, with almost all of them having, if not a heavy love of language, a decent dollop of it.
Ultimately, there is art and creativity in everything, you just need to know where to find it. The type of creativity that creates a stunning artistic composition is the same sort of creativity that creates a masterful Rube-Goldberg system, and the same sort of creativity that creates complex formulas to describe and generalize real life occurrences. Your brain knows the constraints, sub-patterns, and has an array of tools that allow it to intuitively define the form, and you go through processes to fit it.
What I mean is that intelligence and creativity are independent of each other and since most people don't make significant contributions to culture then neither do most intelligent people.
