Why does our American culture disincentivise hot women from engaging in "nerdy" activities?

Hot girls will stop following intellectual pursuits because it is seen as negative social status. This is only something I've seen in the U. S. The girls who are not hot don't give a fuck cause they know there's nothing they can do about their looks. But hot girls are so scared of looking bad and messing up their image. I think there needs to be a huge paradigm shift because intelligence is super sexy.
