An excerpt from a recent paper on the importance of goal abandonment in avalanche terrain.
One way for backcountry skiers to create goal elasticity is by regularly assessing whether or not their plans are robust (work well across a wide range of circumstances and are flexible to unknowns), brittle (work well under limited conditions) or poor (very vulnerable to breaking down) (Cook & Woods, 1999, p. 23). If plans appear brittle or poor then alternative options should be discussed. Moreover, backcountry skiers can go a step further and apply precommitment strategies to their pre trip planning. Via this method individuals “prospectively restrict their access to temptations” (Crocket, Braams, Clark, Tobler, Robbins, & Kalencher, 2013, p. 391). In a backcountry setting this would mean that given the presence of variables A and B, slopes C and D are automatically off limits. This is particularly helpful during moderate or considerable forecasts during which people often wait to see what micro scale/slope specific conditions are like before they make a decision. However, this decision-making method is dependent upon employing the willpower to walk away if conditions prove to be too fragile. Unfortunately, willpower is finite and can erode over time (Crocket et al, 2013, p. 391); therefore decisions made at the end of a day are subject to decreased margins of safety. Conversely, precommitment allows decision makers to abandon plans and or develop an alternative set of objectives before they enter a dangerous environment.
