Like to stay up late? Smartie Pants.

Higher IQs are correlated with later bed times.

“…people with higher IQs are more likely to have values and preferences that just didn’t make sense for our ancestors to embrace. One of those is staying up late. […] Because the nocturnal lifestyle allowed by electricity didn’t exist 10,000 years ago, we must now rely on general intelligence to override our early-to-bed instincts. So those with more of it stay up later.”

Cool.
