In this episode, we explore Donald Rumsfeld's "known knowns, known unknowns, and unknown unknowns" concept and how it applies to risk management in diving. Using the Johari window model of self-reflection, we discuss the importance of understanding risks that divers face, from routine (known knowns) to unpredictable (unknown unknowns). The episode highlights the role of experience, training, and non-technical skills in preventing accidents and managing emergencies. Listeners will gain insights on improving their decision-making and awareness, so they can better navigate both anticipated and unforeseen challenges in their diving journeys.
