In this episode, we explore how authority gradients—the imbalance of power or experience between individuals—can lead to critical mistakes in diving and other high-stakes environments. Drawing lessons from aviation, medicine, and real-world diving incidents, we discuss how the fear of questioning a more experienced person can prevent vital safety concerns from being raised. Whether it's a student diver hesitant to challenge their instructor or a junior crew member in aviation unable to assert their concerns, the consequences can be life-threatening. We highlight the importance of fostering open communication, psychological safety, and mutual accountability to prevent errors and improve safety across all levels of experience.
