In this episode, we examine a near-miss incident involving a CCR diver who narrowly avoided a hypoxic event during a liveaboard dive. Using this real-life scenario, we explore the importance of understanding human factors and causal reasoning in diving, focusing on how fatigue, stress, environmental distractions, and system design can shape performance and decision-making. We discuss the dangers of hindsight bias, the need to learn from "work-as-done" rather than idealized procedures, and how moving beyond blame helps identify systemic issues to improve safety and resilience. Tune in to discover how these lessons can help you dive safer and smarter.
