Today those feel-good vibes around socialization persist, giving happy hour its signature adjective. Except, again, in super-smart people. But why?
"High general intelligence might allow people to better handle new things that humans only recently are encountering, such as managing one's life using computers, smartphones, etc., and not needing (for survival purposes) to associate with friends on a daily basis," he posited. "So, it's more like high intelligence might allow people to more comfortably live outside of natural conditions."
It's a question of adaptation, in other words; in a modern, technology-driven world that relies less on person-to-person contact, more intelligent people might find themselves better able to cope, and are therefore less happy when faced with their savanna-dwelling ancestors' habits.
Don't worry, extroverts can still be smart, too
This isn't to say that social butterflies are always on the dumber end of the spectrum; as with most theories of intelligence and personality, it's not a one-size-fits-all approach.
