The attractiveness distribution out West and back East
Here in the Mountain Time Zone, I'd say the mean is equal to that of Maryland (or other East Coast places), although the variance is smaller here. You won't find Brazilian supermodel lookalikes, but you also don't see much of what are called "trailer trash" either. There must be greater assortative mating for looks on the East Coast.
Perhaps that is because the Bos-Wash area (and others like it) attracts a disproportionate amount of people who are not just smart and successful but also a bit above-average in looks, since that would give them an edge over the smart but plain (hey, that's how the world works). Normally, good-looking women are fine with marrying down as far as looks go, as long as he's successful, and this tends to erode variance in looks, as pretty and ugly genes are mixed into a given family.
But when the good-looking woman is also very smart and ambitious, I don't think she'd be as willing to marry an ugly guy -- she's got it all, so why shouldn't her husband? And similarly for good-looking successful guys -- why shouldn't he marry a woman who's both smart and sexy? This tendency will tend to preserve variance, as pretty genes get shuffled into the same families, thereby forcing more ugly genes to get shuffled into the same families too.
NB: I'm controlling for other variables, like ethnicity and class. It wouldn't be fair to compare the mostly northern European population here to the beauties of swarthy skin and tawny tresses I was used to seeing in Maryland. And it also wouldn't be fair to compare middle vs. upper class people, since the latter are more likely to show a "trophy wife" pattern.
