In this sprawling, strange, and mind-bending episode, Dr. Jud Brewer, a neuroscientist and addiction psychiatrist, discusses the biological origins of our bad habits and how we can change them using new techniques derived from his lab’s research.Well, he tries to talk about that, but I keep interrupting him to try and solve the great mysteries of consciousness and the self. For instance, if you want to hear a neuroscientist quote Einstein — “No problem can be solved from the same consciousness that created it.” — then go from talking about worms and cigarettes to warning you to be careful with your brain or “you can go over the event horizon of the black hole of anxiety,” and the only way out is to add more information to the system to it can propel itself away from the worry black hole — this is the episode for you.
