Subject: [DCHAS-L] Validity of the risk matrix

 

While stumbling around the web with regard to thinking about the risk matrix, I came upon an article that questioned its value:

 

https://medium.com/**At_Symbol_Here**JornMineur/why-the-risk-matrix-must-die-620a7287e7c

 

The essence of the argument, I think, is that estimates of probability are very unreliable.   I’d appreciate the wisdom of the list regarding this essay and its conclusion.
