This is an older article, but I found it and thought it was a good read. Firstly, I know that I always FEEL smarter when I drink, and apparently there is some merit to that thought process. It turns out that smart people drink more.
…more intelligent children, both in the United Kingdom and the United States, grow up to consume alcohol more frequently and in greater quantities than less intelligent children. Controlling for a large number of demographic variables, such as sex, race, ethnicity, religion, marital status, number of children, education, earnings, depression, satisfaction with life, frequency of socialization with friends, number of recent sex partners, childhood social class, mother’s education, and father’s education, more intelligent children grow up to drink more alcohol in the UK and the US.
There is a clear monotonic association between childhood intelligence (measured before the age of 16) and the frequency of alcohol consumption in their 20s, 30s, and 40s. “Very bright” British children grow up to consume alcohol nearly one full standard deviation more frequently than their “very dull” classmates.
It is important to note that both income and education, as well as childhood social class and parents’ education, are controlled in multiple regression analyses of these data from the US and the UK. It means that it is not because more intelligent people occupy higher-paying, more important jobs that require them to socialize and drink with their business associates that they drink more alcohol. It appears to be their intelligence itself, rather than correlates of intelligence, that inclines them to drink more.
So knowing that smart people drink more, you can bet that next time you’re in a bar the ones with the drinks in there hands are the smart ones. Hmm, somehow that just doesn’t sound correct, but who am I to argue with science.
