The best you're going to get is anecdotal evidence at most.
I think universally, arrogance is very much frowned upon, and a lot of intelligent (and not so intelligent) people use their self-perceived intelligence to put others down. So you're going to find a lot of words for arrogant, pedantic or annoying people. But insults for just smart or academically talented people are indeed rare outside of English. At least in my experience.
Fairly good. A B D E is a kind of ambiguous chord with a double suspension. It has an open and pleasant sound in my opinion.
