Podcast: The Next Big Idea
Published On: Thu Oct 01 2026
Description: Martin Seligman founded the positive psychology movement. Now, at 84, he’s shaking up the field all over again. He’s got a new book out. It’s called Agency. And in it, he says, he’s trying to “found a new field.” It’s called psychohistory. “I'm after the rigorous possibility that we can use the tools of psychology to go back in history to ask the questions: What produces innovation? What produces progress? And what produces stagnation?” 🎥 The Next Big Idea is on YouTube!
