The Next Big Idea

FRIENDSHIP: The Science and Power of Life’s Deepest Bond

Friends aren’t just fun to hang out with and handy in a pinch. They’re also a biological necessity. Rufus talks to journalist Lydia Denworth, author of a new book on the science of friendship, who explains why friends — even the online variety — make us happier, healthier, smarter, and more successful.

The Next Big Idea is a weekly series of in-depth interviews with the world’s leading thinkers. Join our host, Rufus Griscom — along with our curators, Malcolm Gladwell, Adam Grant, Susan Cain, and Daniel Pink — for conversations that might just change the way you see the world. New episodes every Thursday.
