According to Robin Dunbar (professor of evolutionary psychology at Oxford), human has a capacity of up to 150 people to have meaningful relationships.
5 people: Your inner circle. Your family, (They consume 40% of the total available social time)
15 people: Your close friend group
50 people: Your friends. You hang out occasionally.
150 people: Your community. You know them and have some personal history.
I was curious about social media’s effect on Dunbar’s number (Dunbar did this research in the early 90s). Found his latest podcast (2017-13minutes), he says actually, when we are connected thousands of people on our social network sites. Still, we are, on average, talking to 150 people privately all the time.
