Humans still have hunter gatherer mental programming, and the more brutish a man, the sexier he is. If a man exhibits traits that ensure success in the wild, it is those traits that turn her on. It took me a long time to understand why women of other races like niggers -- to me, they look like hairless gorillas (with a despicable personality to boot) but apparently, it's those simian, primitive traits that make women wet.
By itself, having a PhD in math or physics is not impressive to 99% of women, and they are merely accessories to a man's attractiveness, and are useless in dating unless you're over 6 feet tall with chiseled features. A Newton-level IQ is useless if you're under 5'10, Asian, Indian, or simply lack high T characteristics.
Amazingly, being extremely high IQ (over 130 or so) is as much of a crutch in dating as being mentally retarded (sub-80 IQ)
