I think there's a cutoff point where the correlation probably inverts. Attractiveness might correlate in the midwit range but geniuses tend to be pretty meh in looks.
A lot of geniuses are perfectly attractive: reasonable bodyfat ratio, good lower back spinal curve, fine neck and arm lengths, great facial symmetry. But a lot of geniuses don't bother with becoming attractive as an additional action, because they don't need to be. So they neglect fashion sense, because a frumpy sweater is easier to wear, or because it's objectively a poor financial decision to "get your nails done" (seriously, a hundred bucks to use a nail file on you and some polish and laquer?!).

Geniuses are definitionally outliers. They have minimal impact here.
