“How Many Friends Can Your Brain Hold?”

A few years ago, evolutionary anthropologist Robin Dunbar, posited that there’s a tight correlation between the size of a primate’s brain and the size of the social group its forms.

On this basis, the size of the average human being’s social network is 147.8—or about 150.

Lately, he’s also found that the size of the brain lobe associated with social connections—the orbitomedial prefrontal cortex—correlates in size with the circumference of one’s social circle. It remains to be seen, however, which causes which.
