8. The intelligent sleep later
This is no longer a feeble excuse for hitting snooze.
Evidence has now been published that people who are more intelligent tend to go to bed later and get up later (Kanazawa & Perina, 2009).
The study examined the sleep habits of 20,745 adolescent Americans and found that on a weekday the ‘very dull’ went to bed at an average of 11:41 and woke up at 7:20.
In contrast, the ‘very bright’ went to bed at 12:29 and got up at 7:52. At the weekend the differences were even more pronounced.
We don’t know the nature of the connection from this study, but perhaps bright people find it more difficult to get to sleep because of all the worrying they’re doing.
