We humans have a bias for the anecdotal rather than empirical and as the book above challenges, even empirical data can be wrong. But, in science its all about proof and the requires research and if its from more than one source then these empirical "black swans" are less likely as we increase certainty. Everything including travelling in avalanche terrain is managing uncertainty. As the cause of death in avalanches is researched by many alpine nations there is a lot of good data to support the statistic that folk mostly die because they either cant breath, or what they are breathing is not rich in oxygen.
I reflect back and realise we never really applied much of it to ourselves and skied off piste with total bravado ignoring things that happened to other people. Skiing back to Verbier off piste with Fiona's dad and a group after coming off Mont Gele, then the group of three strangers behind gets killed later is just one example, and it horrifies me to look back at the sheer stupidity and randomness. As we were with friends in a group it was total group think and feeling safety in numbers. Another example in Switzerland was saying nothing when Fiona skied the back route down to Rougment off the Videmannette with a high risk with Roger and then getting lost in the dark. These were mere tasters to ducking the ropes later trips and bollockings from pisteurs. One time they even stopped the cable car above us as we ducked into a 45deg horror fest. As on ski patrol now, I would arrest myself! These trips were not package tours but often two or three week stays in Chalets of lifelong friends of Fiona's parents so the skiing was pretty immersive and full on with a lot of group bravado. All bad stuff in avalanche terrain.
I often wondered if it was MR that made me interested in the subject but looking back its the sum of lots of parts that all add up, and ski near misses and realisation that your were an ignorant fool - that's probably the biggest one!
