The Evolution of Night Owls...

Night owls are smarter than other people, and n. ow we may know why.

The modern world contains many features our slow-to-evolve brains still find unfamiliar- cars, TVS, hot dogs fried in corn crumbs ect. But the world has always thrown new stuff at us, and more intelligent people tend to adapt more ably.

Satoshi Kanazawa, a psychologist at The London School of Economics and Political Science, argues that, while we have specialized mental modules for navigation, social interaction and other age old tasks- general intelligence is its own module handling only evolutionarily novel circumstances. Prof. Kanazawa has data showing that 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 at night.

A previous study found that evening people are smarter than morning people.
In a new paper, Kanazawa replicates the finding and provides a theoretical ground.
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 GI, stay up later.
