Ravi Agrawal: We all change from the time we're at 12. He says when we look backwards, we can see enormous changes in who we have become. But he adds that it's hard to imagine ourselves as different people in the future. Agrawal is host of a podcast about human behavior and psychological science.
"You are constantly becoming a new person," says journalist Shankar Vedantam. In a talk full of beautiful storytelling, he explains the profound impact of something he calls the "illusion of continuity" -- the belief that our future selves will share the same views, perspectives and hopes as our current selves -- and shows how we can more proactively craft the people we are to become.
