Final answer:
The planner's attitude towards risk is conservative, preferring to plan for low-probability, high-impact events to avoid catastrophic outcomes, similar to buying insurance for rare but severe incidents.
Step-by-step explanation:
The criterion suggested in part (b) likely reflects the planner's conservative attitude towards risk. This is inferred from the context given, which addresses the concept of asymmetric risk and the planning for low-probability but high-impact events. Selecting a course that prepares for potential catastrophic events, even with a low probability of occurrence, highlights a preference for risk aversion and a willingness to accept lesser costs (like wasted time or effort) to avoid a possible devastating outcome. This strategy is akin to buying insurance against unlikely but life-altering incidents. The planner's attitude leans towards being conservative because they value the protection against a catastrophic loss over the potential savings from not taking preventative action when the threat seems relatively improbable.
