In this insightful interview, human factors expert Gareth
Lock discusses the critical aspects of how we should understand sense-making
and decision making especially in ambiguous and high-consequence environments.
The research shows that if performers have 'successful' outcome following a
near-miss, then our perception of the risk is lowered and therefore we are more
likely to erode vital safety margins (training, equipment, standards and
policy).

Gareth explores the importance of distinguishing 'could
happen' events from 'almost happened' events, understanding levels of
uncertainty, mental models, and avoiding the normalization of deviance. What can law
enforcement trainers and supervisors do about this? Gareth explains how we can
develop counter-factual thinking to raise understanding of how our perception
of risk can shift and how to make probabilities more visible.

Finally, Gareth explains his DEBrIEF model of how we can
strategically guide our people to build important self-reflection skills to
improve decision-making and deeply learn from all incidents and near misses.

Gareth Lock is the founder of The Human Diver, an
organization set up to deliver education and research into the role and benefit
of applying human factors, non-technical skills, psychological safety, and
‘just culture’ in sports, military, and scientific diving. He has published the
book ‘Under Pressure’ and produced the documentary ‘If only…,’ both focused on
improving safety and performance by looking at incidents through the lens of
human factors.
