It was more a response to the parent comment. I was suggesting that an intelligent person may choose a mate that's less intelligent because they're prettier which would help resist some of the divergence. They mention assortative mating is greater for intelligence compared to physical aspects like height and weight, but 'prettiness' is a more subjective harder to quantify measure that I would guess plays a larger role in mate selection than just height and weight. This is ignoring the fact that height and weight are probably opposite anyway (women wanting taller men, men wanting shorter women) - so there are some issues there too.
