College students’ tendency to stay up late and sleep in longer may mean higher IQs (intelligence quotients). New studies from multiple universities have shown that people with higher IQs are usually more nocturnal, while people with lower IQs go to bed around nightfall. While the findings are controversial, studies have shown that when and how long one sleeps is directly related to one’s performance during the day.
This was tested on students at the London School of Economics and Political Science; students who worked into the night had higher IQs then those who predominantly limited their studies to the day.
“Eveningness” and “morningness,” as it has been deemed, shows a shift from ancestral humans who were diurnal in nature, and this seems to be a new evolutionary preference found in more intelligent individuals.
People who have more morningness tendencies are comparatively more conscientious people than those with eveningness tendencies. But eveningness tends to be age-related, and college-age students (17-21) are at their peak. After this age, morningness dominates. Yet these patterns are not in our control; sleep patterns are genetically based according to research done at Carnegie Mellon University.
Whether you are an early riser or a late sleeper, college may be the peak of your intellectual processing ability. So when you are stuck studying for a final or writing a paper into the wee hours of the night, think about it this way, you may just have a higher IQ.
