Podcast with Sidney Dekker
This is a really interesting podcast interview with Sidney Dekker, who's one of the most important thinkers in safety. The Jay Allen Show on Safety. (Fast forward through the first 3 minutes, the content is quite interesting.)
Particularly interesting is his discussion of some 'best practices' which come out of a poorly supported chain of work by an insurance analyst. "It turns out, the deeper you dig, he made it up. There's literally no basis for the triangle."
