## Resource

This episode explores why divers don’t truly “lose” situation awareness, but instead run out of the mental capacity needed to maintain it. Through the story of James on a challenging wreck dive, it shows how increasing demands—like current, task focus, and effort—can quietly narrow attention until the bigger picture is lost, even when skills and training are sound. Using two human factors models, COCOM and ECOM, the discussion explains how control shifts from broad, strategic thinking to narrow, reactive behavior as workload rises, and how different layers of awareness—from basic task execution to overall planning—can break down under pressure. It highlights that mistakes are often not about poor decisions, but about limited cognitive resources in the moment. The episode also emphasizes the importance of good preparation, clear decision thresholds, teamwork, and deliberate pauses to manage workload, while showing how reflection after the dive helps improve future performance. Ultimately, it reframes the difference between novice and experienced divers as the ability to manage attention and maintain the bigger picture, not just technical skill.
