Los Angeles-based entertainment attorney Jonathan Handel explains how AI is coming for actors' jobs. Mathematician Emma Zajdela walks David through the surprising math behind how a handful of actors have come to dominate Hollywood. Psychology professor Valerio Capraro reveals the surprising way that using AI can make some people less likely to admit that they don't know something. Psychology researcher Dr. Hyewon Yang shares details of her study challenging some major assumptions about what makes us satisfied in our friendships. For Conspiracy Corner, professor of conspiracy studies Nathan Radke describes how behind every wild conspiracy theory is a person whose life is impacted by their beliefs. Nathan tells the story of a friend he lost. (Check out Nathan's new book Uncover Up: How to Think Clearly in an Age of Conspiracies here.) After that, Dr. Zack Meade discusses his journey from a rough upbringing to becoming an electrical engineer, then a bomb squad technician, and finally an anesthesiologist who fights medical disinformation through online videos.
