Interesting theory. I am reminded of Aeon J. Skoble’s essay “Lisa and American Anti-intellectualism,” included in the anthology “The Simpsons and Philosophy: The D’oh! of Homer.”
The thing about Ross, though, is that he’s not just smart, he’s boring, and by that I mean that the way his intellect generally expresses itself is self-indulgent.
Lisa Simpson, on the other hand, is a complex and interesting character. She exhibits moral concern for the well-being of others and plays jazz saxophone. The scorn that the other characters in The Simpsons display for Lisa is painful because it reveals something deeply troubling about the shame-motivated hostility of American mediocrity.
Ross, like everyone else on Friends, is basically a bland narcissist. Smarter than the others? Perhaps, but what good does intellect do when you’re not doing anything interesting with it?
