Are you a morning lark or night owl? Take the quiz

Do your circadian rhythms indicate that you perform better in the evening than in the morning? Or is the reverse true?

London School of Economics researcher Satoshi Kanazawa says that night owls – folks who stay up late – have higher IQs than larks, people who start their day early. He also suggests that this is a relatively new phenomenon in human history. Nocturnal activity was a dangerous thing prior to the advent of fire. He says today's night owls are defying ancestral-genetic tendencies, and can chose to override their circadian clocks, according to his article in Psychology Today. Kanazawa's theories are also explained in his 2012 book: The Intelligence Paradox: Why the Intelligent Choice Isn't Always the Smart One

But Kanazawa's research is not conclusive. In fact, a 2008 study by Kendry Clay, of the University of North Texas, showed undergrad students who study late at night had lower GPAs than morning types. And a study at the University of Bologna indicated that 'larks' may be more conscientious people.

Would you qualify as a lark or a owl? Take the self-assessment quiz.
