Needing Friends
A quirky but influential 2016 Washington Post piece digs into a counterintuitive idea: smart people may actually be happier with fewer friends, especially in crowded places. The article reports on research by evolutionary psychologists Satoshi Kanazawa and Norman Li, who analyzed data from about 15,000 young adults and found two broad patterns: people are generally less happy in denser environments, and most people feel happier when they socialize more with close friends. But for the most intelligent respondents, those patterns were much weaker or even reversed: frequent socializing made them less satisfied with life.
The first thought that crossed my mind when I read this was memories of my paternal grandfather. He is probably the most intelligent person I've had the privilege of knowing personally. He was completely satisfied having his stack of books and the trusty short-wave radio. As a kid I often wondered if he would even notice if the rest of the world and all the people in it disappeared and how he could need no one and still be perfectly happy. He was not unsocial and was eager to chat with anyone who came around but it was just as well if no one did for long periods of time. The people did not help or hurt the quality of his life. He was completely self-reliant in that regard. Looking back, I don't think he was such an isolated phenomenon, I have a know a few others who really did not care if they had any friends and to a degree that seems a bit incomprehensible particularly as they grew older and even lost their spouses.
To explain what is going on with intelligent people, the researchers use what they call the “savanna theory of happiness.” The idea is that our brains are still tuned to conditions on the African savanna, where humans evolved in tiny bands of about 150 people and extremely low population density — more like rural Alaska than modern Manhattan. In that ancestral world, staying physically close to a small circle of lifelong allies was crucial for survival and reproduction, so our default wiring still treats open space and tight‑knit groups as comforting. Cram those savanna brains into a packed subway and a giant megacity, the theory goes, and you get a chronic mismatch between what we’re built for and how we actually live.
The twist is that highly intelligent people seem less bound by those old settings. Kanazawa and Li argue that general intelligence helps some people handle “evolutionarily novel” situations better, from big-city density to the constant distraction of modern social life. For them, spending extra hours chatting with friends may feel like time taken away from long‑term projects or abstract goals — writing a book, building a company, doing research — so more social contact doesn’t automatically produce more happiness. Brookings scholar Carol Graham, quoted in the piece, frames it this way: for people driven by longer‑horizon ambitions, endless social time can feel like a drag on what really matters to them.
The article is careful to stress that none of this is settled science. “Paleo” explanations of modern life, whether for diet or happiness, have been heavily criticized for oversimplifying evolution and overpromising practical advice. Graham also notes a methodological caveat: the study looks at global life satisfaction (“How satisfied are you with your life as a whole?”), not day‑to‑day feelings (“How often did you laugh or feel angry yesterday?”), and those two lenses can paint very different pictures of well‑being. Even so, the basic findings, that dense cities can sap happiness and that social ties usually help, with some important exceptions, fit into a much larger body of happiness research.
