Some people are night owls, and others are morning larks.  What makes the difference may be their levels of general intelligence. Virtually all species in nature, from single-cell organisms to mammals, including humans, exhibit a daily cycle of activity called circadian rhythm.

According to ”Psychology Today,” intelligent people are more likely to be nocturnal than people with lower IQ scores. In a study run on young Americans, results showed that intelligent individuals went to bed later on weeknights and weekends than their less intelligent counterparts.

Humans, unlike other mammalian species, have the unique ability, consciously and cognitively, to override their internal biological clock and its rhythmic outputs.  For humans, circadian rhythm is not entirely a matter of genetics.  Within broad genetic constraints, humans can choose what time to go to bed and get up.  Humans can choose to be night owls or morning larks.

In ”Study Magazine,” Satoshi Kanazawa, a psychologist at the London School Of Economics And Political Science, reported that IQ average and sleeping patterns are most definitely related, proving that those who play under the moon are, indeed, more intelligent human beings.

His analysis goes back to ancient times, asserting the idea that even in primitive years, people have been known to rise and fall with the sun.

Average brains were conditioned to follow this sleep pattern, while the more inquisitive, intellectual ones want to defy that pattern and create their own.

It’s an unconscious defiance that comes from refusal to acquiesce to the idea of mass appeal.

These findings are reported by “Study Magazine” as such:

Bedtimes and wake-up times for Americans in their 20s by IQ.

Very Dull (IQ < 75)
Weekday: 11:41 pm -7:20 am
Weekend: 12:35 am -10:09 pm

Normal (90 < IQ < 110)
Weekday: 12:10 am -7:32 am
Weekend: 1:13 am -10:14 am

Very Bright (IQ > 125)
Weekday: 12:29 am -7:52 am
Weekend: 1:44 am -11:07 am

Those with IQs less than 75 went to bed by 11:30 pm on weeknights in early adulthood, whereas those with IQs over 125 went to bed around after 12:30 am. This is no coincidence.

The data supports the notion that all night owls feel: the only real time for living is after everyone’s gone to bed. Only after dark can we learn, absorb and study the effects of the day. It’s a necessary self reflection that few humans take the time to make.
