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.
Sums up nicely how I feel about being a night owl:
Staying up late has been, and always will be, an act of rebellion. A defiance of the nine-to-five, the very habit of staying up late is revolutionary.
I also agree with the "challenge authority" part... although this attitude has gotten me in trouble in the past...
