In this episode, we explore the role of punishment in learning and accident investigations, challenging the idea that punishment fosters accountability or safety. Drawing from research by Heraghty, Dekker, and Rae, we discuss how punishment often stifles honesty, trust, and meaningful learning by creating a culture of fear. Using real-world examples, like a tragic drysuit diving accident and the grounding of a liveaboard vessel, we examine systemic issues that contribute to failures and how biases like hindsight and severity affect our responses. Instead of focusing on blame, we advocate for systemic, science-based approaches to foster psychological safety, support accountability, and promote learning to prevent future incidents.
