The next time you're inclined to enjoy an extra glass of wine, consider that it may be a reflection of your intelligence. That is one of the findings from data from the National Child Development Study in the United Kingdom and the National Longitudinal Study of Adolescent Health in the United States.
Childhood intelligence, measured before the age of 16, was
categorized in five cognitive classes, ranging from "very dull,"
"dull," "normal," "bright" and "very bright."
The Americans were revisited seven years later. The British youths,
on the other hand, were followed in their 20s, 30s and 40s.
Researchers measured their drinking habits as the participants
More intelligent children in both studies grew up to drink alcohol
more frequently and in greater quantities than less intelligent
children. In the Brits' case, "very bright" children grew up to
consume nearly eight-tenths of a standard deviation more alcohol
than their "very dull" cohorts.
Researchers controlled for demographic variables, such as marital
status, parents' education, earnings, childhood social class and
more, that may have also affected adult drinking. The
findings held true that smarter kids were drinking more as adults.
Psychology Today takes an evolutionary approach. It argues that
drinkable alcohol is a relatively novel invention of 10,000 years
ago. Our ancestors had previously received their alcohol kick through
eating rotten fruits, so more intelligent humans may be more likely
to choose modern alcoholic beverages.
Although increased alcohol consumption could be a reflection of
exceptional brainpower, drinking more will certainly not make you
any more intelligent than you already are. I'll drink to that.
