According to a 2016 study by researchers at Singapore Management University and the London School of Economics, those who exhibit high IQ scores experience lower life satisfaction when they socialize more often. And that means those smarty pants types likely choose to spend more time alone.
To come to this conclusion, the team analyzed survey responses that were part of the National Longitudinal Study of Adolescent Health. That survey, Inverse explained, measured life satisfaction, intelligence, and health.
In total, the team looked at the responses of 15,197 individuals between the ages of 18 and 28. The data showed that while spending time in dense crowds (for example, at a party) leads to unhappiness. However, socialization with close friends typically leads to happiness. Unless, of course, the person exhibits high intelligence.
These contradicting feelings may all be thanks to our hunter and gatherer ancestors. The authors, Inverse reported, explained the findings with the “savanna theory of happiness.”
“The savanna theory of happiness is the idea that life satisfaction is not only determined by what’s happening in the present but also influenced by the ways our ancestors may have reacted to the event,” reporter Sarah Slot wrote. She added, “evolutionary psychology argues that, just like any other organ, the human brain has been designed for and adapted to the conditions of an ancestral environment. Therefore, the researchers argue, our brains may have trouble comprehending and dealing with situations that are unique to the present.”
In plain speech, this means that while our ancestors got to spend more time with close friends and family in less densely populated areas, we modern humans are stuck being surrounded by strangers all the time thanks to the population boom over the last several thousand years.
“In general, more intelligent individuals are more likely to have ‘unnatural’ preferences and values that our ancestors did not have,” researcher Satoshi Kanazawa told Inverse. “It is extremely natural for species like humans to seek and desire friendships and, as a result, more intelligent individuals are likely to seek them less.”
Beyond an intelligent person’s preferences to be alone, the team also found that smarter people were less likely to feel that they benefited from friendships. Again, this may be because our ancestors tended to benefit from group thinking, while our more intelligent ancestors were able to solve problems alone.
So, next time you feel like bailing on plans with your friends to stay in and watch a movie alone go ahead and do it. It’s the smartest decision you’ll ever make.
