ASC ASC Decision Making & Group Dynamics 1 — Questions and Answers
Question 1: Which cognitive bias causes avalanche professionals to underestimate risk because a route has been traveled safely many times before?
- Confirmation bias
- Familiarity bias (Correct answer)
- Anchoring bias
- Optimism bias
Correct answer: Familiarity bias
Familiarity bias leads professionals to assume repeated safe travel means the route is inherently safe, ignoring changing snowpack conditions.
Question 2: The 'heuristic trap' known as social proof most directly affects group decision-making in avalanche terrain by causing members to:
- Overestimate their own skill level
- Follow others into hazardous terrain without independent assessment (Correct answer)
- Underreport observed red flags
- Rely excessively on technology
Correct answer: Follow others into hazardous terrain without independent assessment
Social proof causes individuals to defer to group behavior, assuming others have assessed risk, which can lead entire groups into hazardous terrain.
Question 3: During a pre-trip briefing, the ASC-recommended approach for surfacing dissenting opinions about terrain hazard is to:
- Allow the leader to make all decisions unilaterally
- Require unanimous consensus before proceeding
- Create a structured opportunity for any team member to voice concerns without judgment (Correct answer)
- Defer to the most experienced member automatically
Correct answer: Create a structured opportunity for any team member to voice concerns without judgment
ASC protocols emphasize a structured, psychologically safe environment so all team members can raise concerns, reducing the risk of heuristic traps.
Question 4: Which decision-making framework used in avalanche safety explicitly separates the 'problem recognition' phase from the 'solution selection' phase to reduce cognitive errors?
- STOP (Stop, Think, Observe, Plan)
- 3×3 Filter method (Correct answer)
- DECIDE model
- RED (Recognize, Evaluate, Decide)
Correct answer: 3×3 Filter method
The 3×3 Filter method structures decision-making across three scales (regional, local, zonal) and three information types, explicitly separating observation from action.
Question 5: A guide notices that clients are eager to ski a steep slope after seeing fresh tracks. The guide's primary obligation under ASC standards is to:
- Defer to client preference since they have paid for the experience
- Conduct an independent hazard assessment regardless of client pressure (Correct answer)
- Allow a test skier to evaluate the slope before group travel
- Contact a senior guide before making any decision
Correct answer: Conduct an independent hazard assessment regardless of client pressure
ASC standards require guides to maintain independent professional judgment; client enthusiasm does not override a certified professional's duty to assess hazard.
Question 6: In group travel through avalanche terrain, the concept of 'one at a time' exposure management primarily serves to:
- Speed up overall group travel time
- Limit the number of people exposed to hazard at any given moment (Correct answer)
- Ensure the guide maintains visual contact with all clients
- Reduce fatigue by allowing rest intervals
Correct answer: Limit the number of people exposed to hazard at any given moment
One-at-a-time exposure limits the maximum number of people who could be caught in a single avalanche, reducing potential burial count.
