Should risk matrices simply be abandoned because of their baked-in flaws?

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?

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
