SH217: Normalization of Deviance (Risk): How Socially Accepted Drift Can Impact Your Diving

Show Notes Summary: In this episode, we explore the concept of normalization of deviance and how it applies to diving. Inspired by a Divemaster's comment about surfacing gas reserves, we discuss how divers can unknowingly drift from safety standards over time, often influenced by social norms or perceived authority. Normalization of deviance, coined by Diane Vaughan, describes how repeated deviations from acceptable standards become normalized when no immediate consequences occur. We contrast this with constructive deviation—deliberate, researched changes to improve safety—and share practical steps to guard against normalization of deviance in diving: establish clear Standard Operating Procedures (SOPs), conduct thorough pre-dive briefs, and hold regular debriefs. Building a culture of psychological safety is essential for divers to feel empowered to question and challenge unsafe practices.
