Counter-Errorism in Diving: Applying Human Factors to Diving7 Loka

SH312: Your Body Can't Cash the Cheque Your Ego Is Writing

We explore how capable, motivated divers can gradually push beyond safe limits when their environment rewards risk-taking and treats near misses as successes. Using the story of a young technical diver who died after entering a strong current, alongside examples from aviation, we examine how normalisation of deviance, practical drift, peer pressure and the need for recognition can erode safety margins over time. The episode asks whether we are recognising skill or simply rewarding luck, and looks at the responsibility of instructors, dive centres and teammates to create an environment where people can challenge decisions and stop a dive without fear of criticism. In an activity where there is no higher authority to stop a diver from making a poor decision, the people around us may be the last line of defence. The challenge is to tell these stories not as tales of foolish people making bad decisions, but as opportunities to understand how reasonable decisions can lead to terrible outcomes—and to recognise the early warning signs in our own thinking before it is too late.
