Marty Makary, a Johns Hopkins surgeon and New York Times bestselling author, returns to The Drive to discuss his latest book, Blind Spots: When Medicine Gets It Wrong, and What It Means for Our Health. In this episode, Marty explores how a new generation of doctors is challenging long-held medical practices by asking critical new questions. He discusses the major problems of groupthink and cognitive dissonance in the medical community and delves into several of the "blind spots" raised in the book, including treatments for appendicitis, the peanut allergy epidemic, misunderstandings about HRT and breast cancer, antibiotic use, and the evolution of childbirth. He explains the urgent need for reform in medical education and the major barriers standing in the way of innovative medical research. Throughout the conversation, Marty offers insightful reflections on where medicine has succeeded and where there’s still room to challenge historic practices and embrace new approaches.
