In this episode, we explore how asking the right questions can transform communication, whether during a dive briefing or a post-dive debrief. We discuss the difference between closed questions, which provide quick answers, and open questions, which encourage deeper understanding and learning. Using techniques like TEDS (Tell, Explain, Describe, Show), we can foster better communication, ensure alignment within the team, and create an environment where everyone feels safe to speak up. We also cover how to frame debrief questions to focus on events rather than individuals, encouraging growth and collaboration. Effective communication is all about how you ask, not just what you ask.

In this episode, we explore how cognitive biases like hindsight bias, severity bias, outcome bias, and confirmation bias impact our ability to learn from accidents and incidents, both in diving and beyond. Using recent Red Sea liveaboard tragedies as a backdrop, we discuss why some events seem “obvious” only in hindsight, how severe outcomes lead to harsher judgments, and the danger of stopping investigations once a single cause is found. By understanding how biases shape our reactions, we can shift from judgment to learning, asking better questions and uncovering the deeper factors behind decisions and actions.

In this episode, we dive into the story of a diver’s lost fin to explore the challenges of decision-making, task fixation, and situation awareness underwater. Through the lens of a training dive gone awry, we uncover how both students and instructors can fall into cognitive traps, focusing narrowly on immediate tasks while losing sight of broader risks. Highlighting the importance of structured debriefing, reflective discussions, and the DEBrIEF model, we discuss how understanding "how it made sense" in the moment can lead to better mental models and a culture of learning in diving. This tale is a reminder that diving isn’t just about technical skills—it’s about building awareness, fostering teamwork, and learning from every experience.

This podcast dives into the analysis of a cave diving fatality at Cenote Nariz in Mexico, based on a detailed report by the Creer Line and Safety Committee. The incident highlights critical lessons for divers in all environments, emphasizing the importance of understanding human factors, decision-making, and context in adverse events. While the exact cause of the diver's seizure remains uncertain, likely contributors include hypercapnia or hyperoxia, exacerbated by equipment and procedural factors. Broader lessons focus on fostering safety cultures, avoiding the normalization of risk, maintaining equipment rigor, and embracing systems that encourage learning without blame. Join us to explore how these insights can improve safety and awareness across diving disciplines.

This episode explores the power of small, intentional changes to improve teamwork, leadership, and performance in diving. Drawing from the Human Diver team's experience with a new training platform, we discuss how focusing on key skills like communication, task prioritization, and role clarity can create significant improvements. By embracing curiosity, running effective debriefs, sharing stories, and taking actionable steps, we can build safer, more effective diving practices. Change starts with small actions, and owning that change is the key to lasting impact.

Leadership in diving is critical for navigating uncertain situations and achieving successful outcomes, whether you're teaching students, leading a dive project, or running a dive center. Drawing lessons from Ernest Shackleton's legendary leadership and modern theories of influence, this episode explores how effective leaders go beyond authority and management to inspire trust, foster psychological safety, and build personal connections. We discuss six key strategies for diving instructors, including defining a clear purpose, embracing humility, managing conflict constructively, learning from mistakes, adapting leadership styles, and showing genuine care for others. Tune in for actionable insights to enhance your leadership in the water and beyond.

Debriefs are vital for learning and improvement, but making them effective can be challenging. This episode explores how the DEBrIEF framework, inspired by aviation and human factors experts, provides a structured approach to debriefing that fosters psychological safety. We discuss the importance of vulnerability, showing that even experienced divers make mistakes, and how leading by example encourages honest self-reflection. Real-world examples highlight how debriefs can move beyond surface-level feedback, helping teams identify areas for growth and create meaningful solutions. With the right structure and environment, debriefs can become powerful tools for continuous improvement in diving and beyond.

In this episode, we explore the meaning of accountability and its role in learning and improvement. Is accountability about assigning blame, or can it be a tool for growth? We discuss the difference between backward-looking accountability, which focuses on punishment, and forward-looking accountability, which emphasizes understanding, empathy, and systemic change. Drawing on lessons from healthcare and diving, we highlight the importance of hearing multiple perspectives, addressing the needs of those impacted, and fostering a culture of responsibility over blame. By sharing real-world examples, we show how open conversations and a Just Culture approach can lead to better outcomes, stronger relationships, and meaningful improvements in safety and performance.
