Dr. Paul Bloom is a Professor of Psychology at the University of Toronto, and the Brooks and Suzanne Ragen Professor Emeritus of Psychology at Yale University. Paul studies how children and adults make sense of the world, with special focus on language, pleasure, morality, religion, fiction, and art. He is the author of seven books, including his latest Psych: The Story of the Human Mind.

In this episode, we sample some of the many, many topics covered in Psych, including Freud, evolutionary psychology, language development, moral development, and social cognition. We also talk about Paul’s early research on language development and moral cognition, my own research on pubertal hormones and brain development, and the meta-psychology of what makes podcasts interesting.
