Counter-Errorism in Diving: Applying Human Factors to Diving
Gareth Lock at The Human Diver
Human factors is a critical topic within the world of SCUBA diving, scientific diving, military diving, and commercial diving. This podcast is a mixture of interviews and 'shorts' which are audio versions of the weekly blog from The Human Diver.
Each month we will look to have at least one interview and one case study discussion where we look at an event in detail and how human factors and non-technical skills contributed (or prevented) it from happening in the manner it did.

SH110: Looking in the (Cultural) Mirror...
In this episode, we explore cultural awareness and how understanding our own culture is key to improving relationships and performance in diverse environments. After attending a training session at Abbey Communication, I learned that we often judge others based on our own biases without realizing it. The course used the Trompenaars and Hampden-Turner model, which outlines seven dimensions of culture, to help us understand these differences. By recognizing and respecting cultural variations, we can work toward better communication, teamwork, and safety in multi-cultural settings, rather than assuming others share our viewpoint.

SH109: Anyone could have done that...!
In this episode, we discuss the concept of "common sense" and how it's not always as common as we might think. Using the example of Columbus and his "uncommon sense" solution to standing an egg on its end, we explore how knowledge and experience shape our understanding of what seems obvious. Just because something appears simple to one person doesn't mean it's clear to others who haven't had the same experiences. This idea is crucial when explaining the need for training or coaching to others, as assumptions about common sense can hinder problem-solving and safety improvements.

SH108: How Much Are You Willing to Risk?
In this episode, we explore the parallels between decision-making in diving and the concepts from Daniel Kahneman's "Thinking, Fast and Slow." The discussion focuses on how divers often face tough choices when equipment malfunctions, similar to the mixed gambles described in the book. While staying on the boat may seem like the safe choice, the fear of missing a dive can lead to riskier decisions, driven by loss aversion and regret. We emphasize the importance of using logical, System 2 thinking in these situations and considering the potential consequences of your choices.

SH107: Summary of RF4 Paper: Human Factors in Rebreather Diving
In this episode, we discuss the importance of human factors in rebreather diving, highlighting key themes from the Rebreather Forum 4 conference. Rebreather diving, while offering unique opportunities, is far more complex than traditional scuba due to its intricate systems and hidden failure modes. The talk covers the role of systems thinking in improving safety, the need for a just culture, the value of psychological safety, and the importance of non-technical skills like teamwork and communication. We also explore the challenges of implementing human factors and why they are essential for the future of safe rebreather diving.

SH106: Language Matters: An HF Approach to Reviewing an ‘Accident Analysis’
In this podcast episode, we discuss a recent accident analysis published by RAID, which was framed as a hypothetical event but turned out to be based on a real-life diving incident without full consultation with those involved. The focus is on how we frame learning opportunities in diving and the importance of understanding the decisions made in the moment rather than placing blame after the fact. Effective accident analysis must explore the conditions and pressures present, fostering empathy and a learning culture within the diving community. A PDF review of this case is available in the show notes.

SH105: Mistakes are good- learning from mistakes is sometimes better than getting it right
In this episode, we discuss why mistakes are a valuable part of the learning process, especially in scuba diving training. While most instructors aim for their students to perform perfectly, making mistakes actually helps students learn more effectively. Mistakes provide opportunities for problem-solving and critical thinking, which can lead to deeper learning. We explore how immediate or delayed correction of errors, depending on the student's experience, enhances this learning process. The episode also highlights the importance of conducting effective debriefs to create a psychologically safe environment, where students can openly discuss their mistakes and learn from them.

SH104: Communication- What stops people speaking up?
In this episode, we explore the challenges of effective communication and the barriers that often lead to misunderstandings and conflicts. We discuss how stress, language differences, and personal insecurities like the Imposter Syndrome can prevent clear communication, both underwater and on land. We also highlight the importance of creating a psychologically safe environment where everyone feels comfortable speaking up. Ultimately, good communication requires effort from both parties to ensure that the message is understood, not just transmitted. Tune in to learn how to improve your communication skills and build better connections.

SH103: The Dunning Kruger effect- Incompetent (or Competent?!) and Unaware
In this episode, we explore the Dunning-Kruger effect, a cognitive bias where people with limited skills or knowledge in a particular area tend to overestimate their abilities, while those with more expertise may underestimate their competence. This effect explains why some new divers might think they’re better than they are, while more experienced divers might not realize how skilled they’ve become. We discuss how continuous learning and staying humble can help us accurately assess our abilities, leading to safer and more effective diving practices.

SH102: Decision Making- How do we explain our decisions to others?
In this episode, we explore the challenges of explaining decisions to others, especially when they don’t share the same knowledge or experience. Jenny recounts a personal story about deciding not to dive a local canyon system again due to safety concerns, despite it seeming straightforward to others. The incident highlights the importance of situational awareness, good communication, and building a shared mental model within a dive team to ensure everyone understands the reasons behind decisions. This helps prevent misunderstandings and promotes safer diving practices.

SH101: Running out of gas- Why does this happen and how can we prevent it?
In this episode, we discuss a personal diving incident where I ran out of gas underwater—a situation that could have been fatal but wasn't due to quick thinking and luck. The experience highlights the dangers of complacency and the importance of maintaining situational awareness, even during routine dives. We explore how easily small oversights can lead to critical mistakes and the value of debriefing and sharing experiences to learn from them. This incident serves as a reminder that staying vigilant, especially when things seem routine, is crucial to safety in diving and beyond.
