Paige is a scientist and writer. She’s a professor of psychology at the University of Texas at Austin, where she directs the Developmental Behavior Genetics lab and serves as Director of Clinical Training. She’s the author of The Genetic Lottery: Why DNA Matters for Social Equality, and her new book is Original Sin: On the Genetics of Vice, The Problem of Blame, and The Future of Forgiveness. It’s about the eternal question of what sin is; and where it comes from; and whether our guilt is justified. We had a great chat.
