What does expertise decision-making rely on according to the mountaineering heuristics?

Expertise in decision-making, particularly within the context of mountaineering heuristics, heavily relies on previous experience to inform decisions. This concept emphasizes that seasoned professionals draw upon their past encounters, learning from both successes and failures, which empowers them to make more informed and effective choices in high-stakes environments.

When faced with complex scenarios, experienced individuals can recognize patterns or anticipate potential challenges based on what they have previously encountered. This reliance on past experience enables them to navigate the uncertainties and risks inherent in mountaineering situations more effectively. By applying lessons learned from similar past situations, they can make quick, yet informed decisions that are vital in ensuring safety and success.

While other options might suggest utilizing new strategies, relying on others' decisions, or adhering strictly to guidelines, they do not capture the essence of expertise in the same way that leveraging past experiences does. This foundational reliance on experience is what distinguishes expert decision-making in mountaineering and rescue contexts.
