Beauty and Intelligence incredibly linked (same level as education)

In a previous post, I show, using an American sample from the National Longitudinal Study of Adolescent Health, that physically more attractive people are more intelligent. As I explain in a subsequent post, the association between physical attractiveness and intelligence may be due to one of two reasons. Genetic quality may be a common cause for both (such that genetically healthier people are simultaneously more beautiful and more intelligent). Alternatively, the association may result from a cross-trait assortative mating, where more intelligent and higher status men of greater resources marry more beautiful women….

Mostly the former, as it explains female bequeath too it should be genetic. Assortative mating usually applies to objective attractiveness (the famed 10-scale) for both sexes, skewed relationships rarely last long without something else to make up for the gap.

Regardless of the reason for the association, the new evidence suggests that the association between physical attractiveness and general intelligence may be much stronger than we previously thought.

… Attractive NCDS respondents have the mean IQ of 104.23, whereas unattractive NCDS respondents have the mean IQ of 91.81.  The difference between them is 12.42. This mean difference implies a correlation coefficient of r = .381, which is reasonably large in any survey data…..

Huge IQ bridge, on par with eugenic/dysgenic effects? I’d love to see expanded profiles (marital status at 30, for example).

By pure coincidence, the correlation between physical attractiveness and intelligence in NCDS is exactly the same, down to the third decimal point, as the correlation between intelligence and education. Both correlations are .381. Everybody knows that intelligence and education are very highly correlated. What they don’t know is that physical attractiveness is equally highly correlated with intelligence as education is. 

In other words,

If you want to estimate someone’s intelligence without giving them an IQ test, you would do just as well to base your estimate on their physical attractiveness as you would to base it on their years of education.

oh damn wow ah

I’ll leave these here:

“Privilege” has statistical backing!
The stereotypes, again, are true!

Maybe humans will branch into an Eloi and Morlock scenario? The IQ difference is huge, the SD I calculated for the summary result (both sexes) is 8.78227, population SD is 6.21 with population variance of 38.5641 in IQ. Huge values.

1. Be civil. 2. Be logical or fair. 3. Do not bore me.
