The fuck you talking about? It's the very opposite. There's absolutely no correlation between attractiveness, IQ or even Health!
Example:
Theories in both evolutionary and social psychology suggest that a positive correlation should exist between facial attractiveness and general intelligence, and several empirical observations appear to corroborate this expectation. Using highly reliable ...

there was no relationship between attractiveness and actual academic performance (r = 0.03), but a strong positive correlation between attractiveness and perceived intelligence (r = 0.81), attractiveness and perceived academic performance (r = 0.74) and attractiveness and perceived conscientiousness (r = 0.81).
However a whitepill emerges:
There was a significant correlation between older age and higher actual academic performance
Facial attractiveness has been suggested to provide signals of biological quality, particularly health, in humans. The attractive traits that have been implicated as signals of biological quality include sexual dimorphism, symmetry, averageness, adiposity, and carotenoid-based skin colour. In...

Show me the studies that show otherwise, if they do exist, please.
