Is Sleeping Late a Sign of Laziness or Intelligence?

Sleeping in Late

Sleeping in late could be a sign you’re brainy.

If you have a tough time pulling your head off the pillow in the morning or settling into bed at night, it could be a sign you’re brainy.

Satoshi Kanazawa, a psychologist at The London School of Economics and Political Science has done extensive research on the connection between sleep patterns and intelligence.

His findings indicate that people with higher IQs tend to stay up later, and subsequently wake up later in the day.

Sleep & Smarts Stats:

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

Very Dull (IQ < 75)
Weekday: 11:41 P.M.-7:20 A.M.
Weekend: 12:35 A.M.-10:09 A.M.

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

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

Kanazawa theorizes that humans used to rise and fall with the sun, 10,000 years ago. Now that electricity enables a more nocturnal lifestyle, below-average and average brains still want a sleep pattern that resembles our ancestors’. Whereas above average brains will ignore that impulse and find stimulation during the later hours.

    That must be why all the teenagers sleep so late, they are so smart. Give me a break.

    Actually, Rockysima, that’s a different thing all together. Teenagers sleep late into the day because their bodies require it. The processes that rampage a teenager’s body are not to be compared with those of developed adults.

    The IQ in Kanazawa’s article wasn’t determined by a proper test. It was based on discussions with the children, something they call verbal intelligence. This is not very relevant I would say …

    I rarely sleep at all, I must be a mad genius! LOL.

    My sleep time is a mess… what category am I in? I usually woke up about 2 hours later than the previous day, it takes me two weeks to be 1 day late than other people.

    I don’t have jobs, school or a girlfriend. I’m something you call a NEET (and a shut-in) that’s why i can lived with this lifestyle.

    However, money is the only thing I’m comfortable with.

  7. Wow Says:

    Funny how it’s determined by less than an hour.  This study is stupid and meaningless.

  8. Jimmy Says:

    sounds like projection.

    Where are the standard deviations?
