Up All Night to Get Lucky Proven Statistically

51d824aee8086The early bird may get the worm, but the night owl gets laid. At least, that’s the conclusion of Dario Maestripieri, a professor of comparative human development at the University of Chicago. And he has the statistics to back it up.

In a previous study, Maestripieri surveyed more than 500 graduate students from the University of Chicago Booth school of Business to assess financial risk aversion among male and female students. It showed that those prowling the night had higher levels of acceptable risk financially. It also asked about their sleep patterns and other behavioral tendencies.

He had all the info he needed right there, so why not run the numbers? Maybe those risk-taking tendencies extend beyond the financial realm?

“Night owls, both males and females, are more likely to be single or in short-term romantic relationships versus long-term relationships, when compared to early birds,” Maestripieri said. “In addition, male night owls reported twice as many sexual partners than male early birds.”

You hear that? Twice as many.

Maestripieri goes on to say that sleep tendencies can be influenced by genetic and hormonal characteristics, and that female night owls had higher levels of cortisol, which may be one of the biological mechanisms explaining the higher risk behavior.

Or it’s just common sense.

You know who is staying out late and partying all night? Drunk single people who are out for a good time. You know who’s not? People in committed relationships with a dog or a kid at home to take care of.

The study, “Night owl women are similar to men in their relationship orientation, risk-taking propensities, and cortisol levels: Implications for the adaptive significance and evolution of eveningness,” was published by Maestripieri in the journal Evolutionary Psychology.

    For the grad school population, perhaps! I’d be curious about different populations.
