Video: Just Culture in Practice

April 16, 20261 min read

This guide serves as a practical guide for small organisations in high-risk sectors to implement a Just Culture, moving away from a traditional blame-centered approach.

It emphasises the importance of psychological safety and local rationality, helping leaders understand that human errors are typically driven by systemic conditions rather than individual malice.

The guide outlines six foundational pillars for building trust and introduces an eight-question review process designed to analyse incidents fairly. By prioritising restorative accountability, the guide encourages organisations to separate learning from discipline to ensure honest reporting and long-term safety.

Ultimately, it provides a framework for identifying systemic improvements while clearly defining the rare instances where individual accountability is necessary.

Gareth Lock is the founder of The Human Diver and Human in the System — two organisations built on a single conviction: that most unwanted events in high-risk environments are system failures, not people failures. Through structured courses, immersive simulations, incident investigation, and keynote speaking, he brings frameworks from military aviation and academic human factors research into the practical reality of diving and high-risk industry. His work spans recreational and technical divers learning non-technical skills for the first time, through to senior safety leaders restructuring how their organisations investigate, debrief, and learn. Everything sits under one guiding principle: be better than yesterday.
