I've met lots of intelligent blondes, actually. Ofcourse, if you already believe blondes are less intelligent, chances are you're gonna interpret things you see or hear within your own paradigm, which almost always will strengthen it.
Besides that, why would hair color have anything to do with intelligence in the first place? The only reason that the idea of blondes being dumb exists is because of some lame, old sexist idea.
