'Drinks' is really ambiguous. Wine drinkers average something like 18 points better than beer drinkers on IQ tests, indicating that there are very large confounding variables at play.

True. You really have to believe it's alcohol that's making a difference to just talk about "drinks". I do believe they would have noticed if it were only red-wine drinkers who benefited (via reservatol, say), though. I imagine their data included the kind of drinks imbibed.

The 18 IQ points of wine > beer is clearly mostly snobbery/signaling :)
