I was expecting it. That is, that the more intelligent, who scored high on a vocabulary test, would drink more than the dumb, who scored low. Look at the other correlates above. But I’ve rarely seen such a stark near-monotonic trend with Wordsum. You can try to control for variables. Race doesn’t matter much for what it’s worth, the trends stay pretty much the same if you constrain to whites. I decided to check the “Bible” variable, which measures literal interpretation. As expected controlling for fundamentalism eliminates much of the Protestant vs. non-Protestant difference, as well as exacerbates the sex difference (fundamentalist women are much more teetotaling than men), but it really didn’t effect the rank relation on many categories. The regional and Wordsum difference remains even among those who are fundamentalists or irreligious. I think this points to the social aspect of drinking. Even if you like to drink, if you’re circle of acquaintances tends not to, you won’t get a chance to drink as much. Conversely, if drinking is expected, there’s more pressure to bend your norms to please your friends. (via People of class drink alcohol | Gene Expression | Discover Magazine
