If blondes are perceived as more attractive, then being blond may create valuable opportunities that do not require onerous investments in education and training. The dumb blonde stereotype may thus stem from the fact that blondes rationally choose to invest less than others in education and other forms of human capital.Lest you think this is a gender-neutral generalization, it is not. It's predicated on the idea that men are drawn to looks and women to status and money.
Get it? Blondes don't pursue education because they'd prefer to marry well.
