In this episode, we dive into the complexities of decision-making in high-risk environments, focusing on why some choices that lead to accidents might seem baffling but are understandable in context. We discuss Todd Conklin's and Chris Perrow's ideas on "Normal Accidents," highlighting how unforeseen events can occur despite experience and training due to factors like hindsight and outcome biases. We’ll explore the three types of decision-making—skills-based, rules-based, and knowledge-based—explaining how each influences our actions, especially in unfamiliar situations. Lastly, we’ll address how understanding decision-making can lead to safer diving practices by analyzing actions and events before they turn into incidents.
