We live in a society enamored with divisions, but Nicholas Christakis lives by the outlandish idea that humans are fundamentally similar — and has devoted much of his career to uncovering the universals of social experience. (He's a lumper, not a splitter.) The Yale professor and author of many books — including Blueprint and Apollo's Arrow — unpacks his fascinating findings in evolutionary biology, describes the price we pay for the spread of ideas (namely, germs), and reflects on that now infamous moment on the Yale quad six years ago.
