The Philosopher
Aristotle once wrote that a human is “by nature a social animal; an individual who is unsocial naturally and not accidentally is either beneath our notice or more than human. Society is something that precedes the individual. Anyone who either cannot lead the common life or is so self-sufficient as not to need to, and therefore does not partake of society, is either a beast or a god.” Even 2,000 years ago, long before the dawn of modern science, the father of western philosophy could see that our social character was inseparable from our identity and our connection to society.

The Anthropologist
Of all the species in the animal kingdom, humans possess the largest brains relative to body size. Group that with the fact that a species’ brain size directly correlates to the size of its social group and you can conclude that our large brains evolved to prioritize human interaction. Using primate brain size as a benchmark, anthropologist Robin Dunbar was able to extrapolate the maximum number of social connections a human could maintain. The number? 150. Interestingly enough, in his book, The Tipping Point, Malcom Gladwell recounts the story of Gore-Tex, whose management structure requires they build a new office anytime their headcount gets too high. The number? 150.

The Neuroscientist
Matthew Lieberman, a neuroscientist from UCLA and author of Social: Why Our Brains Are Wired to Connect, makes the case that being socially connected is not just an artifact of millions of years of evolution, but essential to our survival. “In a sense, evolution has made bets at each step that the best way to make us more successful is to make us more social.” His research has shown that even at rest, the brain defaults to a social state; years of evolution have trained resting brains to be best prepared to reactivate within a social context.
