If you only have a few close friends, you may feel like an outcast in society. However, studies show that loners typically have greater intelligence than popular folks. So, if you prefer being alone most of the time, don’t beat yourself up about it.

Evolutionary psychologists Satoshi Kanazawa and Norman Li conducted a national survey involving 15,000 respondents aged from 18 to 28. The research revealed that people who lived in densely populated urban areas reported lower life satisfaction in general and that the more people socialized with close friends, the higher their self-reported happiness was. Of course, the only exception occurred when it came to intelligent individuals.

“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. More intelligent individuals were actually less satisfied with life if they socialized with their friends more frequently. In other words, when intelligent people hang out more with their friends, they feel less happy.

What makes highly intelligent people so different from the average person? They prefer to spend their time alone usually because they have a larger goal in mind. They see socializing as a distraction when they could use their time more wisely. Also, they don’t appear to be as sensitive to population density as those with lower IQs. Therefore, they can navigate the challenges of modern living more efficiently and perhaps find novel solutions to most significant problems.

According to Kanazawa and Li’s savanna theory of happiness (稀树草原幸福理论), in the past, we would have lived in tribes instead of densely populated cities, helping to avoid loneliness. “Our ancestors lived as hunter-gatherers in small bands of about 150 individuals,” they explain. “In such settings, having frequent contact with friends was necessary for their survival.” While we no longer live in small tribes now, most of us still require close friends and family to survive. That may explain the epidemic of loneliness affecting millions of people worldwide.

However, highly intelligent people are the exception to this theory. They don’t mind spending most of their time alone. So, if you don’t have many friends, you may have learned to overcome your primitive instincts. Perhaps you represent this small group of humans who can thrive in the modern era.
