Are smart people more likely to binge drink?

Looks like it:

In a multiple ordinal regression, childhood intelligence has a significant (ps < .00001) effect on adult frequency of both binge drinking and getting drunk, controlling for age, sex, race, ethnicity, religion, marital status, parental status, education, earnings, political attitudes, religiosity, general satisfaction with life, taking medication for stress, experience of stress without taking medication, frequency of socialization with friends, number of sex partners in the last 12 months, childhood family income, mother’s education, and father’s education.  I honestly cannot think of any other variable that might be correlated with childhood intelligence than those already controlled for in the multiple regression analyses.  It is very likely that it is childhood intelligence itself, and not anything else that is confounded with it, which increases the adult frequency of binge drinking and getting drunk.

This is from Satoshi Kanazawa’s blog. His book Why Beautiful People Have More Daughters is quite thought-provoking.
