I guess it depends on what you mean by smart and dumb and what you personally value in a partner.
I have a friend who thinks any girl who doesn't have a developed taste in things like music and culture is dumb, while I tend to overlook those things more and value things like ambition/high character standards and someone who isn't afraid to genuinely express their opinions or be open minded to different ideas/people. I don't care if she doesn't like the same music as me, but it would matter to me if she was dismissive or accepting towards such differences.
