Andy, I don't think the issue is that people don't want to be judged based on things they can't control. I think the issue most people have with "superficiality" is that, rather than taking a person as a whole, superficial people focus on one thing: looks, money, fame, what car they drive, whatever. I would say someone who focuses only on intelligence, or only on profession, or only on whether they're good parenting material, is just as "superficial" as someone who focuses only on looks. We tend to associate superficiality with preference for attractiveness because frankly we're a visual species and that's the most common type of superficiality out there. Plus, it's such a temporary thing to focus on: beauty is fleeting, but stupid is forever.
