Sounds like just another half-cooked theory, to me. My own theory is that creative people are simply more sensitive and are therefore driven crazy, by those unimaginative, boring people, who have nothing better to do, than try to stifle creativity in others.
"Those two blues are exactly the same! There's no difference! Are you crazy?"
"That'll never work! If it would, someone else would've already thought of it! Are you crazy?"
"Just follow the directions! You can't just make up your own way, to do something! Are you crazy?"
Is it any wonder, creative people sometimes go crazy?
