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.

SH66: The Value of Loops for Learning: Don't Just Fix the Diver /Instructor
In this episode, we delve into the concept of learning loops in scuba diving, inspired by the works of Chris Argyris and Donald Schön. We explore single-loop learning, focusing on immediate problem-solving like fixing a malfunctioning buoyancy control device (BCD), and double-loop learning, which involves analyzing underlying issues such as calibration errors in a rebreather. Then, we introduce triple-loop learning, which considers broader contexts like team dynamics and learning culture within the dive community. Practical examples illustrate each loop's application, from troubleshooting equipment issues to enhancing training programs. Drawing parallels with other high-risk domains like wildland firefighting, we emphasize the importance of fostering a learning culture and embracing continuous improvement at every level of diving. Whether troubleshooting a BCD or revising safety protocols, remember that each dive offers opportunities for growth and deeper understanding, contributing to a safer and more knowledgeable diving community.

SH64: Price vs Quality: The Efficiency-Thoroughness Trade Off
In this episode, we delve into the complexities of dive training agency standards and the challenges faced by instructors in evaluating student performance. While standards outline specific skills, determining their mastery isn't always straightforward. New instructors, lacking experience and nuanced judgment, often prioritize efficiency over thoroughness due to external pressures like time constraints and financial considerations. This efficiency-thoroughness trade-off (ETTO) can compromise the quality of instruction, leading to pass grades for students who may not be fully prepared. The root issue lies in instructors' limited exposure to diverse student experiences and the reluctance of dive centers to invest in extensive observation opportunities. As an industry, we must reconsider this trade-off, where financial concerns often outweigh safety and quality. Ultimately, the responsibility falls on individual divers to evaluate their skills, raising questions about the integrity of certification processes and the adequacy of diver preparedness.

SH59: Drift vs Advancement: How do we push limits safely?
In this podcast episode, we delve into the distinction between normalization of deviance and constructive deviation/advancement within the diving community. Normalization of deviance, as coined by Diane Vaughen, describes the gradual acceptance of unsafe practices as the norm, whereas constructive deviation involves a deliberate, open exploration of new methods to enhance safety and efficiency. Through examples such as the evolution of nitrox usage and the risks associated with solo diving, we explore how attitudes toward failure shape these approaches. Standard procedures typically incorporate fail-safes to prevent errors, while constructive deviation involves consciously researching and adopting alternative practices. Join us as we dissect these concepts and their implications for diver safety and training.
