 was a famous sociologist named Robin Dunbar. He came up using neuroscience to understand the average person should have 150 social connections. It's 8, 25, 150. Write those two numbers down. You should have about eight hyper-close friends. You can include family in this. These are like your best friends. Humans aren't trained to just have one best friend. You have like four to eight very close friends. They call those bands, B-A-N-D, like a band of people. Then you have, or I call them squads. Like in the military, that's a squad size, eight. And then you have like 25 is like your next fairly close set of people in your life. Then you have 150 acquaintances. And the math works out, because you need to track all the different relationships. That works out to 10,000, a web of 10,000 connections that your brain will be doing the math on. Because you'll be tracking how friend number eight interacts with acquaintance number 116. That's why it's called Dunbar's number. You can Google the math on it. It comes out to 10,000, a web of 10,000 connections. Our brain is perfectly suited for that from our hunter-gatherer days.
