Studies were conducted to see if smart people sleep the same amount of time as not so smart people. It turns out that smart people are more likely to be able to teach their brains new habits – such as staying up late. Staying up late was a habit that was strange to our ancestors. Our ancestors might have been happier with a simple existence but modern man has moved to a more complicated world than what our ancestors lived in.
Think about the past, as you move back through history you find that people had fewer and fewer reasons to stay up late – unless under threat.
Just because you stay up late and feel like a zombie doesn’t mean you’re smarter! You must be clear headed. This means you are able to read and process information or can complete the manual tasks required of you without endangering anyone. If you can do this, it means that your brain is able to do more work than those who tire easily.
The psychologist conducting the study found that night people are more intelligent than morning people!

Sleeping Times for the Ordinary and Extraordinary
A study from Satoshi Kanazawa, psychologist at The London School of Economics and Political Science, shows that intelligence and night-owl tendencies are correlated. Kanazawa surveyed Americans in their twenties, and found the following:
- Those with an IQ of over 125 tended to go to bed around 12:30 a.m. and wake up around 8:00 a.m. on weekdays, and to go to bed around 1:45 a.m. and wake up around 11:00 a.m. on weekends.
- Those of normal intelligence tended to sleep from 12:00 a.m. to 7:30 a.m. on weekdays and from 1:15 a.m. to 10:15 a.m. on weekends.
- Those of below normal intelligence tended to sleep from 11:45 p.m. to 7:20 a.m. on weekdays and from 12:35 a.m. to 10:00 a.m. on weekends.
