That makes sense though. The more closely faces represent the golden ratio, the more attractive they're judged to be. Therefore, the more similar they are in that aspect, the more attractive they are. So there are a lot more ways to be ugly that there are to be attractive.
That's interesting because familiarity also increases attractiveness, which is why 'unattractive' people (think actors) might be judged somewhat attractive despite their unattractive features...which in turn make them more memorable, thus more attractive.
