“This brief research note aims to estimate the magnitude of the association between general intelligence and physical attractiveness with large nationally representative samples from two nations. In the United Kingdom, attractive children are more intelligent by 12.4 IQ points (r = .381), whereas in the United States, the correlation between intelligence and physical attractiveness is somewhat smaller (r = .126). The association between intelligence and physical attractiveness is stronger among men than among women in both nations.” (link)
