In this episode, Dr. Killeen rewinds to 1903, when the Wright Brothers took flight just weeks after being told humans probably never would. From there, he draws a parallel to the “rules” many of us live by in dentistry and leadership—beliefs repeated so often they start to feel like facts. He breaks down the Illusory Truth Effect and challenges you to question the assumptions shaping your practice, your schedule, and your confidence. A thoughtful, easy listen that might just help you rethink what’s actually possible.
