This meta-analysis investigated the effects of occupational stress (OS) on safety and health outcomes in construction. 20 studies over 20 years, including >6k construction workers was included (not such a big sample given all of the research in construction safety, indicative of the relatively poorer quality of research that didn’t meet their inclusion criteria). [Trigger… Continue reading Relationships between occupational stress and occupational safety and health outcomes amongst construction workers: A meta-analysis of evidence from the past twenty years

The author also proposes some stop rules to help navigate infinite regression. I’ve previously posted articles critical of the status of ‘root causes’, who argue it is more a process of implicit or explicit… Continue reading The issues of ‘root causes’ and infinite regression (the endless search for the causes of causes)

A brief read covering the concept of noise, pertaining to judgements. This is based on the work from Kahneman, Sibony and Sunstein. From the article: · While biases in judgements have captured a lot of attention, “it has been suggested that ‘noise’ (defined as an undesirable variability in human judgements) is a highly important, yet under-recognised… Continue reading Why do doctors make poor decisions? Spotlighting ‘noise’ as an under-recognised source of error in clinical practice
“The fetishism of scientific management” – a 1912 criticism
An interesting critique of Scientific Management approach from 1912. Great title – ‘fetishism of scientific management’.
