SH15: Normalisation of Deviance

In this podcast episode, we delve into the concept of "Normalization of Deviance" in the context of diving. While it may seem like rule-breaking, it's actually about the social acceptance of deviating from established standards and practices. The episode explores how this phenomenon occurs in diving, where 'safety' is a social construct based on the absence of adverse events rather than legal rules. It delves into examples of drift at various levels, from industry-wide issues to individual behaviors like reducing gas minimums or exceeding depth limits. To address this, the episode emphasizes the need for performance-based standards, psychological safety, leadership development, and a Just Culture to prevent and correct the normalization of deviance.
