On the brain: Binge drinking and intelligence

A lot of fascinating discussions about what's going on in your brain - such as the implications of binge drinking, the rise of depression, and the symptoms of concussions - are bubbling this week.

Do intelligent people drink more?

A blog post in Psychology Today claiming that more intelligent people are more likely to binge drink has met with some heated reaction. The author Satoshi Kanazawa wrote in October that "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." The basis of this argument: Data showing correlations between intelligence and drinking.

His explanation is that alcohol consumption is relatively recent in human history, and intelligent creatures seek evolutionarily novel stimuli. In fact, that was also the rationale behind a highly controversial study from earlier this year suggesting that higher IQ is linked to liberalism, atheism, and male sexual exclusivity.

Kanazawa's blog post has come under fire in the Huffington Post and an even more scathing critique in Psychology Today. Psychologist Stanton Peele points out in the Huffington Post that college graduates are the "most likely to drink but the least likely to binge drink," according to a government survey he cites. Education is not the same as intelligence, but the two tend to be associated, he said. And, moderate drinking has been associated with health benefits such as lower cardiovascular risk.

As to whether evolutionary psychology as a whole is "dangerous bull--," as Peele suggests, is perhaps not so clear-cut.

Cleaner, but more depressed

It's no secret that depression is on the rise in America, and one possible explanation is that we're just too clean. Dr. Charles Raison, Emory University psychiatrist and CNNHealth Mental Health Expert, says that our ramped-up hygiene may be getting rid of bacteria that we need to fight inflammation, which can lead to depression. Raison and colleagues wrote about this in the Archives of General Psychiatry. Allergists have also speculated that our society's over-cleanliness has led to a rise in food allergies. Does this mean exposure to outcast microorganisms would help? That remains to be seen.

Not just a head bump

Drowsiness in a high school female athlete may not be a sign of sleep deprivation - it could be a concussion. A study in the Journal of Athletic Training shows that boys and girls say they have distinct symptoms of concussion, Time reports. For the high school guys, concussion symptoms include amnesia and disorientation.

Dentist the menace

If you're terrified of the dentist, you're not alone. A large study of England, Wales and Northern Ireland found that 19 percent of women, but only 10 percent of men, have extreme anxiety when going to the dentist, according to the BBC. If you have a serious fear of getting your teeth fixed and want support, check out Dental Fear Central.

More than luck

Are you destined to get ahead? Making good financial decisions, or doing well at gambling, may come from genetics. You might be getting lucky in the market because of the "warrior gene," which influences how good you are at maximizing value from such decisions, according to a new study in the journal Proceedings of the Royal Society B, Nature reports. Apparently, those with the genetic variant MAOA-L make risky calls about 41 percent of the time, but are good at ruling out bad choices. Of course, this is a small and preliminary study in this area. MAOA is called the "warrior gene" because it has been linked to aggression in the past.

      The problem with cannabis is that it's associated with people that the researchers (who're looking for work by the way) don't want to consider intelligent. These researchers have nothing better to do but make up nonsensical theories and then try to prove them right just like phrenologists did years ago to make themselves feel superior.

      Saying drinking can cause cancer is like saying brushing your teeth fights heart disease. If you're genetically predisposed to getting cancer, you're going to get cancer, if you're not, you won't. Everyone's health is unique, because we are like snowflakes. There are those who can treat their bodies terribly their entire lives and not get cancer, and those who can do everything they can to try to prevent it and still get it.

    "Here at PsychologyToday.com we have invited the leading academics, clinicians and authors in our field to contribute their thoughts and ideas in the form of blogs"

    Not exactly peer reviewed. Also, the study was a data analysis of children from a study in the U.K and has no breakdown in IQ for anything above 125.

    Casual observation of people wherever I've lived reveals a very different conclusion from this. Neither the most intelligent (i.e., WAY above 125), nor the least intelligent (developmentally disabled) are the heaviest drinkers. Maybe things are different in the U.K. than in the U.S...

    Having done my share of drinking in bars over 40 years and spending a few nights in detox recently with about 2 dozen others, I would say in general, no, most people who drink too much and too often are not overly intelligent and in fact are probably below average in general. I learned a lot about alcohol addiction in 2 days in detox and I quit drinking as a result after many years of moderately heavy use although have never had a DUI or other problem. Alcoholism knows no class or status, but ingeneral, there is a tendency for lower status folks to abuse it more than others at least in my experience.

    Let me try to say this simply. Intelligent people think more about more things than less intelligent folks. The more you know about life, the harder life is to handle. Intelligent people are more likely to be depressed, because they are aware of more that there is to be depressed about. It's no surprise they drink more. One of the professions that has some of the highest instances of drinking problems is the medical profession. These people realize more abouut human suffering than most, because they, first of all, study it and are also exposed to it at work. Ignorance is bliss.

    My personal reason for drinking is to feel better about thinking about what makes me feel like crap–like dealing with all the people who treat me like I'm dumb. I may act dumb, but I bet I can outsmart and outwit just about anyone who thinks they are better than me. I don't over indulge, I just enjoy.

      Many people drink in order to feel more "comfortable" in social situations, to worry less about what others think of them.
      It's too bad that we don't treat people equally, and some people are treated generally worse than others, and people resort to things like drinking to cope.
      Try to stand up for yourself when someone treats you poorly and concentrate on giving kindness to others and to your own self.

    I have been sober for about 25 1/2 years and I see that even intelligent people make choices to drink too much, but on the other hand I have seen lower IQ people make the same choices. Alcoholism is a non discrimorty illness.

    "The basis of this argument: Data showing correlations between education level and drinking."

    That's not at all what the article in Psychology Today said. I think that Ms. Landau needs to read the PT article again. In fact, the article specifically states that education level was controlled for, so the results are for intelligence level after controlling for education level. Reading is fundamental.

      Tell that to the historians of Winston Churchill, Julius Caesar, Simon Bolivar, Napoleon Bonaparte, Jesus Christ and George Washington, all who partook freely at one time or another or consistently. The lesser of these men would have ben at least 3 times the average modern teetotaler in stamina, intellect,general health and sheer guts. On a lesser note, I was in my best health when I lived in the tropics, worked hard in the heat until I wore wreaths of salt on my clothes, considered cold beer and rum part of my staple diet and womanized to the best of my abilities, five years after working in an air-conditioned office, living what many would consider an (unvoluntarily) virtuous, mostly dry life here in the Deep South Bible Belt and consistently going to bed early, I am suddenly ailed with chronic allergy ills, night cramps, GERD, kidney stones and higher than normal blood sugar.

    Kanazawa is right on in most of his evolutionary findings. Although I differ in opinion about attractiveness. A female will always be able to reproduce regardless of attractiveness, so it follows that optimization of DNA reproduction necessitates a female birth when a male birth would be considerably less optimum. Also I find that when a male pursues a female to mating success the offspring will tend to be male than female but in either case the attractiveness will be more profound. Also on the pursuit factor, when a male decides on pursuing a female time and resources are spent so it follows that at some level the male will pursue selectively and the result is higher attractiveness and intelligence. Conversely when a female chooses her mate the result is a lessening of attractiveness.

    In my experience, (and not to sound too arrogant, but read on . . .) being smart in a stupid world is painful. Bright people need something to either slow them down and make them fit in and/or to dull the pain.

    But the issue is also self-correcting (at least in my case). I USED to be a lot smarter. I also USED to drink . . . a lot.

    But eventually, I must have killed enough brain cells that now I function more or less like a "normal" person and don't drink anymore.

    I'm tired of this "binge" drinking BS. Drinking with the primary intention to get drunk? Maybe. But all I hear about people getting drunk is that they're "binge" drinking. Get off it already! When I drink, I drink to enjoy the particular beverage of choice, which is usually homebrewed beer. It tastes really good, but I don't drink it with the intention to get drunk, that's a side effect, a bonus, not the primary goal.
    My contention would be that intelligent people drink to enjoy their alcohol and getting drunk is an added bonus, not a primary goal.

    I enjoy a drink at times, which may be tequila, or a dark beer, like a Belgian Carolus, at 8.5% alcohol, but the idea is to relax, not to get drunk. In my 44 years, I have only been drunk 4 times, at a party where only snacks were served and rum was available, once after being suspended from a job, and twice with company, who drank too. So, I feel that when your mind is working so hard, so long, alcohol brings a break, and we get to slow down, which is so enjoyable. I also find a Guiness refreshing. But for beer, one is enough.

    Why aren't you smart people talking about the other 2/3 of the article?

    We know that self-neglect (poor hygiene) almost invariably accompanies depression. We know that some forms of bacteria that are naturally found on human skin can interact with other biological factors that together reduce and possibly protects against depression. What if self-neglect (as defined earlier) is a protective mechanism/response to the onset of depression? If it is, then perhaps excessive cleanliness should be discouraged.

  45. Intelligent drinker - but...

    "Alcohol consumption is relatively recent in human history."
    Really.... Well, only if you consider 4000 years ago to be recent! The ancient Egyptians drank wine and beer, and even wrote down the recipes. These so-called "studies" are pure nonsense, and nothing but vehicles for promoting personal political goals and/or burning through grant money – the vast majority of which comes from taxes.

    • True Medicine

      Considering that most anthropologists agree the modern-looking human species has been around for over 200,000 years, 4000 years does in fact qualify as "relatively recent." There is 50 times more human history before humans began drinking alcohol.

      As for the rest of your comment, are you speaking only to the studies mentioned in the article, or to research in general? You don't seem to know much about how research is generally funded, that much is clear. A "grant" is money awarded that does not have to repaid; the source has nothing to do with whether it qualifies as a grant. Depending on the nature of the research, the vast majority of grants available are from private organizations, where the research is conducted often on behalf of the grant provider, or because the organization(s) providing the grants have an interest in the area studied.

      Without grants, most research simply could not be done. Government grants are very strict with their criteria, and mostly are reserved for areas that have enormous social impact, such as public health issues, education, etc. The US government does not fund extraneous research, nor does it provide funding at the whim of a researcher. without adequate tax revenue, there would be no government research grants. Without grants, there would be no research. Without rsearch, we might as well be living in a world like that of 4000 years ago.

      Cheers.

    It helps numb your mind when it is reeling with too much thought. You can work too much, you can eat too much, you can drink too much, you can sleep too much, you can think way too much. It is unhealthy to turn into a self-absorbed, imperious, pompous kind of pseudo-Nietzsche with storm clouds following you everywhere.

    I love to drink!
    There are many people who say I'm smart so I guess it's true. Plus the booze makes it easier to deal with all the morons.

    I would be interested to know what the controls were for this study. I would say it is likely we are really seeing is a spurious correlation between drinking and intelligence. For instance, perhaps college students drink more than those in the same age group who are not in college ... and college attendance tends to be correlated with intelligence. Or, perhaps those who have more income drink more ... and income tends to be correlated with intelligence. Either way, the relationship is not between drinking and intelligence; it is between income or college attendance and drinking. Has this study controlled for these confounding factors?
