Time with friends just isn’t the same with a screen in between you. That’s a struggle many have faced recently, with half of Americans saying they’ve lost touch with at least one friend during the pandemic. It can be sad, but is falling out of touch with friends normal? How many relationships should we maintain, and what are the different kinds of friendships we need anyways? Evolutionary psychologist Robin Dunbar has been studying social relationships for 50 years, and he has answers.

This is an episode of Am I Normal? with Mona Chalabi, another podcast from the TED Audio Collective. You can find and follow it wherever you're listening to this.
