It's also worth considering that your hypothetical might be anything but! At extremely high levels of intelligence the rate of extreme social disorders skyrockets up to "most" (I recall the cutoff for 50% happening at ~165 IQ, but it continues to rise even after that, limited primarily by our lack of data on IQs much higher). I'm not entirely sure if this analogy is appropriate, but just as organisms with more cells are more likely to produce cancer, it seems minds with more thoughts racing through them are just as damaged by some small percentage of errant thoughts (some are extreme delusions, some are just the product of the isolation of a brilliant mind growing tired of a world, retreating from it, losing touch with how to interact with excellence and subtlety, and seeing even less subtlety in the world, simply growing more tired of it, ending with many extremely intelligent people simply unable to interact with others in any normal way).
