Why Are Smart People Ugly?

Why are smart people usually ugly? I get this isn't always the case, but there does seem to be a correlation. Attractiveness doesn't predict intelligence (not all ugly people are smart), but it seems like intelligence can be a good predictor for attractiveness (smart people are usually on the ugly side). Keep in mind, I have nothing against people who are really brilliant, I've just always wondered.

The answer: They’re not.

Oh, how the Explainer loves a false premise.
