Are risk matrices better than nothing? Should we use them because we don’t have a better alternative? Or, can matrices result in assessments **worse than random chance**, reward arbitrary calculations, and reinforce human perceptual filters and risk blindness? Are many of the issues of matrices baked into their design, rather than resulting from the users?… Continue reading Should risk matrices simply be abandoned because of their baked-in flaws?
Problems with Risk Matrices Using Ordinal Scales
This covers some core problems with risk matrices. It’s argued that while they’re established tools, appearing to be “authoritative, and intellectually rigorous”, this “could be just an illusion …bred by the human bias of uncertainty aversion and authority bias”. Hence, matrices have “many flaws” that can “diminish their usefulness to the point where they become… Continue reading Problems with Risk Matrices Using Ordinal Scales
On folk models, ontological alchemy and other critical perspectives in risk
A few extracts with probably little to no links between them – but critical perspectives of techniques and their worldviews and applications. Not systematic. Refs at bottom of article. Dekker on ‘ontological alchemy’ Dekker argues that, just like alchemists tried to turn base metals into gold, practitioners and scholars perform ontological alchemy by trying to… Continue reading On folk models, ontological alchemy and other critical perspectives in risk
Safe AF ep #5: Is what we find in investigations, what we fix?
Conventional logic suggests that we fix the gaps that we find in investigations. But is this the case? Is the investigation process more a game of sociopolitical whack-a-mole, finding and fixing the things that are easily solved or understandable, or tolerable to the organisation? Ref: Lundberg, J., Rollenhagen, C., & Hollnagel, E. (2010). What you… Continue reading Safe AF ep #5: Is what we find in investigations, what we fix?

Who should manage worker safety to reduce occupational accidents?
This study investigated how workplace accidents are affected by who manages occupational safety – owner/partner, managing directors, branch managers, OHS officers or safety representatives. They control for company size. Survey data was collected was across the EU (at least 32 countries and >44k companies). For context: Results They found: · “evidence that it is not… Continue reading Who should manage worker safety to reduce occupational accidents?
Safe AF ep #4: Relationship between fatal and non-fatal accidents based on 23k accidents
Is there a connection between fatal and non-fatal accidents, or is it a fallacy to focus on the minor potential events with the hope of managing the major events? Today’s study explores these relationships based on 23k reported serious accidents in the Netherlands. Ref: Bellamy, L. J. (2015). Exploring the relationship between major hazard, fatal… Continue reading Safe AF ep #4: Relationship between fatal and non-fatal accidents based on 23k accidents

Safety climate and fatigue have differential impacts on safety issues: Safety climate, fatigue, and safety issues
This study explored the links between safety climate, fatigue and several safety issues (actual safety incidents reported, near-misses experienced, safety underreporting). >11k navy personnel were surveyed (survey/self-declared, so consider limitations). Key findings: · “Safety climate affected underreporting the most, followed by likelihood of experiencing a near-miss, but had the weakest impact on actual safety reporting” · “Conversely,… Continue reading Safety climate and fatigue have differential impacts on safety issues: Safety climate, fatigue, and safety issues
