NEW RESEARCH: Why smart people are happier and better off with fewer friends

Hell might actually be other people — at least if you're really smart.

That's the implication of fascinating new research published in February 2016 in the British Journal of Psychology. Evolutionary psychologists Satoshi Kanazawa of the London School of Economics and Norman Li of Singapore Management University dig in to the question of what makes a life
well-lived.

They use what they call "the savanna theory of happiness" to explain two main findings from an analysis of a large national survey (15,000 respondents) of adults aged 18 to 28.

First, they find that people who live in more densely populated areas tend to report less satisfaction with their life overall. "The higher the population density of the immediate environment, the less happy" the survey respondents said they were. Second, they find that the more social interactions with close friends a person has, the greater their self-reported happiness.

[Yes, money really can buy happiness]

But there was one big exception. For more intelligent people, these correlations were diminished or even reversed.

"The effect of population density on life satisfaction was therefore more than twice as large for low-IQ individuals than for high-IQ individuals," they found. And "more intelligent individuals were actually less satisfied with life if they socialized with their friends more frequently."

Let me repeat that last one: When smart people spend more time with their friends, it makes them less happy.

Kanazawa and Li explain: "Residents of rural areas and small towns are happier than those in suburbs, who in turn are happier than those in small central cities, who in turn are happier than those in large central cities."

Why would high population density cause a person to be less happy? There's a whole body of sociological research addressing this question. But for the most visceral demonstration of the effect, simply take a 45-minute ride on a crowded rush-hour Bus Line train and tell me how you feel afterward.

Kanazawa and Li's second finding is a little more interesting. It's no surprise that friend and family connections are generally seen as a foundational component of happiness and well-being. But why would this relationship get turned on its head for really smart people?

"The findings in here suggest (and it is no surprise) that those with more intelligence and the capacity to use it ... are less likely to spend so much time socializing because they are focused on some other longer term objective," she said.

Think of the really smart people you know. They may include a doctor trying to cure cancer or a writer working on the great novel or a human rights lawyer working to protect the most vulnerable people in society. To the extent that frequent social interaction detracts from the pursuit of these goals, it may negatively affect their overall satisfaction with life.

Smarter people may be better equipped to deal with the new (at least from an evolutionary perspective) challenges present-day life throws at us. "More intelligent individuals, who possess higher levels of general intelligence and thus greater ability to solve evolutionary novel problems, may face less difficulty in comprehending and dealing with evolutionary novel entities and situations," they write.

If you're smarter and more able to adapt to things, you may have an easier time reconciling your evolutionary predispositions with the modern world. So living in a high-population area may have a smaller effect on your overall well-being — that's what Kanazawa and Li found in their survey analysis. Similarly, smarter people may be better-equipped to jettison that whole hunter-gatherer social network — especially if they're pursuing some loftier ambition.
