Smart People Sleep Late

SleepingInteresting article from Robert Alison in the Winnipeg Free Press earlier in the year:

Sleep is a fundamental component of animal biology. New evidence confirms that, in humans, its timing reflects intelligence. People with higher IQ’s (intelligence quotients) tend to be more active nocturnally, going to bed later, whereas those with lower IQ’s usually retire to bed sooner after nightfall.

The precise function of sleep is arguable. But, accumulating evidence shows that lack of sleep in humans and animals can result in obesity, high blood pressure and reduced life spans. Drowsiness impairs mental performance. For instance, 37 per cent of all motor vehicle accidents are caused by drowsy motorists, according to a University of Pennsylvania study. Even minor sleep deficiencies impact on body chemistry.

According to Juliette Faraco of Stanford University, sleep loss generates a proportionate need for “sleep rebound”. One of the most controversial and significant recent findings is the correlation in humans between the earliness/lateness of sleep preferences and intelligence.

Robert Bolizs at Semmelweist University, and his coworkers, have shown that encephalograms during sleep illustrate how sleep elements are directly related to “wakeful cognitive performance.” Studies by researchers H. Aliasson and colleagues show the timing of intervals of sleep “correlates closely” with student academic achievement.

Extensive research by Satoshi Kanazawa and colleagues at the London School of Economics and Political Science have uncovered significant differences in sleep-timing preferences among people, depending on their IQ scores. People with higher IQ’s are more apt to be nocturnal night-owls. Those with lower IQ’s tend to restrict their activities primarily to daytime.

    Left to my own preferences, I’d stay up until three or four in the morning and wake up in the early afternoon every day.

  • Randy Carruthers

    Studies that divide things into these bipolar divides are extremely without any residual value… I could do a study that would determine that since a slight more fraction of people of higher IQ might, for instance, prefer the color yellow over brown then brown must therefore be preferred by people with a lower IQ and therefore idiots… There have also been quite a few studies that show that the more you sleep the lower your life expectancy is. There are also others that show those who sleep drastically less than 6 or 7 hours have a shortened life expectancy (on average given the control group and tested subjects in the experiment). Hormones such as testosterone and estrogen also get out of whack producing what we understand as the cranky bastard who just woke up syndrome… in short, this study is a load of crock.

    • Guest

      Sounds like ol’ Randy here is a morning person.

    • didge

      dividing things into divides? OH NO!! You do realize that there is a hell of a lot of statistical psychological research that relies on correlational studies like these, correct? And that there is actually a genetic link with whether somebody is a morning/evening person?

    • Mike

      You do realise most of science is based on a process of reductionism, where we break more complex processes down into simpler parts. I don’t see how your examples even back up your argument. So because studies have found other correlations which you cant or havent shown to be untrue, this one is untrue? Good argument bro.

      You couldn’t tell whether this study is good or not from this small article anyway, would have to look at a full methodology to see if it had any of the flaws you are so quick to ascribe to it. Although if it’s peer reviewed research, I’d trust the research peers over a random internet nobody who can barely put together a coherent grammatical structure.

      I definitely think Randy is a morning person, the butthurt backlash is strong in this one.

    • noprotein

      Perhaps “may be predisposed…” rather than “are” would hold more sway but let’s not forget this is an article with snippets. The actual study most likely contains far more factual summaries.

        • Chunterosa

          personally, i’m sick of people who think it’s cool to be so horrid to a section of population simply for being mentally handicapped. personally, when i see people using the r word, i see that they are probably perfectly willing to use the n word. after all, it’s cool to disparage people for being born with traits that aren’t the same as us. yay for slurs!!!

          • Dustin Neumann

            Except the R word. “Retarded” Had a meaning before it was used as an insult.
            In our language the N word did not.

          • noprotein

            This x 1000

          • Robert Jackson

            SHHHHH don’t share facts about words that are in the definitionary

          • noprotein

            It’s nowhere near the ‘n’ word (in full) because the n word has one meaning and it is at the highest level of derogatory as well as demeaning a massive group of the population. Whereas ‘retarded’ has a true meaning which was given a terrible connotation and cruelness to it which has, over time, come to mean two things: it’s original singular meaning of “less advanced in mental, physical, or social development than is usual for one’s age.” and a colloquialism for ‘stupid’, ‘idiotic’, or perhaps even “slow for one’s mental, physical, or social development”.

            I think it’s in poor taste when you use it purposefully towards a disabled person in any capacity. However, as context is ALWAYS key, when saying it to a friend who continuously tries to tell me evolution isn’t real, I feel perfectly justified and well within my PC boundaries.

      • Nick

        Hey, it also turns out that a point cannot not have validity. Only an argument can. And an argument being a collection of points, is valid when the conclusion is necessarily true given that the points are all true… So even if he was using the wrong word, his argument for this article being true would still be vaild, just not sound. You should probably study some logic or philosophy before flaming someone about it.

        • Alex

          From which standpoint? The argument is right if we assume the premises are true. In this case the argument is not sound from boolean stand point. BTW I stay up till 4 am just because its a habit since high school, and I’ve been self employed since then. I am 21 now and never took an IQ test so I don’t know where I stand, but I would like to consider my self being one of the few.

    Thats the stuff I wish i had access to when i was in school. So when I was tardy to school I would just show my teacher a Stanford artical and say it’s not my fault it’s my biology.
    Seriously though even when I was a wee one I would find myself up very late at night. I thought I was a vampire, some say just highly antisocial but this brings some clairity to my nocturnal behavior.
    Also I find it easier to read and do tasks after the sunsets. Come on why else would owls be a sign of wisdom.

    I think you’re all being conceited or stupid.
    Higher IQ doesn’t necessarily mean you’re smarter than someone who has a lower IQ.
    I’m pretty sure everyone knows IQ is Intelligence Quotient, this directly corresponds to brain capacity.
    The simple fact you’re brain is bigger than most doesn’t mean you’re smarter. Like most “capacities” we know of, it can be “full”, such as computer memories. The bigger the computer’s memory drive the MORE info it can store.
    If you have a higher IQ, it just means you can store more info in that cranium.
    Now we move on to the “slackers” and “workaholics.”
    If someone with a high IQ does not constantly look for and find new info, he would not be as “smart” as someone who might have a low IQ but is constantly reading up on new info and knowledge.
    Only difference is the limit to how much knowledge a lower IQ individual can retain compared to an individual with higher IQ.

    • MysticBun

      Judging by your comment it would seem that you have reduced intelligence quotient to a mere function of memory and the retaining of information whereas in fact this is merely one aspect of overall I.Q. A person with a high I.Q. generally will be able to solve logical problems with more consistency than someone with a lower I.Q. So correlating intelligence with information storing whilst that is a function of intelligence it is not the entire picture.
