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

Does probability exist?

Really cool article talking about probability – does it exist? Is it an objective property of the world, or a subjective and constructed phenomenon? And more. Thanks to Ben Cattaneo for putting this on my radar. Can’t do this justice and I’ve skipped HEAPS, so check out the full paper. Thanks to **** for highlighting… Continue reading Does probability exist?

How People Understand Risk Matrices, and How Matrix Design Can Improve their Use: Findings from Randomized Controlled Studies

This study explored different risk matrix designs on user comprehension and use of matrices. I’ve posted a lot of research dunking on risk matrices (RMs), so here’s another olive leaf focusing on designing something potentially more useful. [** I still stand by the critical orientation, since we have little good evidence that RMs improve risk… Continue reading How People Understand Risk Matrices, and How Matrix Design Can Improve their Use: Findings from Randomized Controlled Studies

Ethical use of Risk Matrices

I found this an interesting section of a paper which I’ll post soon – talking briefly of the ethics of risk matrices. They’ve barely touched the surface, but good to see the reference to ethical practice in risk. Some points are that: Study posted maybe next week. Ref: Sutherland, H., Recchia, G., Dryhurst, S., &… Continue reading Ethical use of Risk Matrices
