AVALANCHE RISK, HUMAN FACTOR AND HEURISTIC TRAPS
Any kind of activity taking place in a snow-covered mountain environment is subject to the risk of avalanche release and consequently the risk of burial.
Worldwide statistic figures emphasize a significant difference as for the rate of accidents among those who practice recreational activities on snow and professionals, despite that in the last decades science has made major achievements in the knowledge of physical parameters of avalanches (snow science, avalanche dynamics, meteorological and morphological factors) and that ski-mountaineering/backcountry skiing courses organized by CAI, the Italian alpine club, are generally focused on accident prevention (evaluation of stability, avalanche release dynamics, setting up and leading an excursion). It has in fact been ascertained that most of the accidents take place because of human error, but scientists still have not managed to properly understand the decision-making dynamics and the factors affecting it. Some authors (see References) have shown that expert people, though being subject to higher risks, are able to develop their own decision-making process, therefore reducing human errors, particularly heuristic traps. |
