“I think, therefore I err”: An article about ‘good errors’, heuristics and intelligent systems

“Every intelligent system makes errors”, so said Gerd Gigerenzer. Here’s a couple of page extracts from a 2005 paper. Not sure if I’ll summarise it or not (it’s really interesting, but tough to capture in a summary…) The paper: ·        Challenges the rationalistic and normative ideal as cognition as purely a logical and rational one, ignoring… Continue reading “I think, therefore I err”: An article about ‘good errors’, heuristics and intelligent systems

Automation’s lacklustre effects on fatal accidents & cheap migrant labour hampering adoption of engineering controls

REALLY interesting findings from Associate Professor Masahiro Yoshida. It suggests that automation over a historical context didn’t really drive down workplace injuries since it tended to be employed in already mature industries. And, ready access to cheap migrant workforces may hinder broader industrial risk reduction due to a negative correlation with automation investment. And the… Continue reading Automation’s lacklustre effects on fatal accidents & cheap migrant labour hampering adoption of engineering controls

Does counting change what counts? Quantification fixation biases decision-making

Saw this posted on LinkedIn (forget who shared it) and found it really interesting. This study, across 21 experiments and 23k participants in managerial, policy and consumer contexts, studied how numbers and quantification distorts decision-making Context: ·         Quantification is spreading and has reached into almost every personal and professional area ·         New-borns are given Apgar… Continue reading Does counting change what counts?

The use of weak signals in occupational safety and health: An investigation

This study explored current knowledge and use of weak signals in safety. Thanks to Clive Lloyd for sharing this a couple weeks back. As you’d expect, this sort of topic, based on accidents, is pretty replete with hindsight and outcome knowledge but is interesting nevertheless. Extracts: ·        They have been defined as an “…imprecise early indication… Continue reading The use of weak signals in occupational safety and health: An investigation

Hollnagel on “Human error”: error as cause, process or outcome

Not much to say – some extracts from a 2007 chapter from Erik Hollnagel, unpacking whether we really need “human error”? I knocked the summary up last night and will probably post in the next couple of weeks. Oh man, I need to give up on chapters…what a slog. He argues: ·        Human error “is not… Continue reading Hollnagel on “Human error”: error as cause, process or outcome

The rule of three: Situation awareness in hazardous situations

“The rule of three provides a mechanism that converts the risk continuum into a dichotomy for the purposes of decision-making. It does not, however, ignore the expertise of operators … Put another way, the rule of three structures expert decision-making; it does not replace it”

Contextualising new safety paradigms: A study in a large Australian construction company

This study explored the presence, implementation, appetite and feasibility of 12 principles representing “new safety paradigms”. It involved focus groups with 53 participants and a cross-sectional survey of 514 employees. I’ve skipped HEAPS (actually, the entire results section – so check out the full paper). Background: ·         “The review by Karanikas et al. (2022) revealed… Continue reading Contextualising new safety paradigms: A study in a large Australian construction company

Learning from normal work: How to Proactively Reduce Risk When Nothing Goes Wrong

An interesting article from Marcin Nazaruk, exploring learning from everyday work. Skipping a bit, so check out the full article. First he says that while it’s important to learn from failure “it is too late”. For one, diminishing incident rates “can no longer accurately reflect safety performance … and simply focusing on behaviours and unsafe… Continue reading Learning from normal work: How to Proactively Reduce Risk When Nothing Goes Wrong

Safety audits almost never target the actual sources of operational danger

Reflecting on my first audit study – we found things many would expect (image 1), like audits largely focusing on administrative items, and superficial matters. And for my construction friends, we found ‘toolboxes’ used a lot to address an issue, even if that issue didn’t have any reasonable connection to something that you’d need to… Continue reading Safety audits almost never target the actual sources of operational danger

Leveraging Ergonomics and Human Factors (E/ HF) for community impact: what have we learned about how to make a difference

This was a banger – exploring the application of community ergonomics with a strong systems lens. If you’re interested in HF/E, systems thinking, social dynamics, power gradients and more then this will interest you. Can’t do it justice, so a few random extracts. Extracts: Finally they talk about ways to improve this practice – via… Continue reading Leveraging Ergonomics and Human Factors (E/ HF) for community impact: what have we learned about how to make a difference
