I gave a talk about Bayesian analysis of risk and uncertainty at the Nordic Chapter of SRA meeting in Copenhagen on Nov 7th. Despite having only 15 minutes, I Think I got the message clear. Bayesian analysis is the way to quantify epistemic uncertainty by probability, it is to my knowlege the only principle to integrate data and expert judgement and it this has been known for a long time. Bayesian analysis is not used as often as it could, and the most obvious reason for that is that we, the assessors, are not familiar enough with Bayesian analysis.
