Finnish researchers gathered data on 3, fraternal and identical twins and found that the sibling who was the first to develop verbal ability—speaking words, reading and using expressive language—also tended to be the first to try alcohol and to drink more heavily throughout adolescence.
Earlier speaking age is also associated with better academic performance throughout middle and high school and a higher chance of graduating from college—and achieving higher levels of education is also correlated with higher alcohol consumption.
According to the Savanna-IQ Interaction Hypothesis posited by evolutionary psychologist Satoshi Kanazawa, the human brain has trouble dealing with situations that did not exist in the Pleistocene environment we evolved in, but some brains less intelligent ones have more trouble than others.
When Kanazawa analyzed data on UK children, he found that link. Drawing on the results of the National Child Development Study, which tracked for 50 years all British babies born during one week in March , Kanazawa found that kids who scored higher on IQ tests grew up to drink larger quantities of alcohol on a more regular basis than their less intelligent peers.
The older you get, the more you drink—but only if you went to college. The National Survey on Drug and Health use found that among college graduates, Not-so-bright men drink more, but only because they are likely to be binge drinking. According to the same study of nearly 50, Swiss males, ages , moderation is the smartest course. Why is there so much contradictory research on the relationship between alcohol and intelligence? One problem may be that most studies rely on participants' self-reporting about their alcohol intake, which isn't the most reliable measure.
The jury may still be out on the connection between your smarts and your cocktails, but there is overwhelming evidence that heavy drinking has extensive negative health effects. Damon Linker.
