In Sheck Exley’s view, what underpins effective decision-making underwater?

Effective decision-making underwater, according to Sheck Exley’s philosophy, is fundamentally rooted in field experience. This experience encompasses a diver's practical knowledge gained from varying underwater scenarios, enabling them to assess situations based on firsthand encounters rather than relying solely on theoretical knowledge or outside influences. Divers with substantial field experience are better equipped to anticipate challenges, enhance situational awareness, and make informed judgments in real-time, especially in the dynamic and often unpredictable environment of underwater exploration.

In contrast to relying heavily on technology, which can sometimes fail or provide false information, or succumbing to impulse reactions, which may lead to hasty and potentially dangerous decisions, field experience allows divers to develop a rational approach grounded in exposure to diverse underwater conditions. Similarly, while social influences from peers can play a role in decision-making, the priorities of safety and technical proficiency stem from an individual's experience rather than external pressures, reinforcing the value of self-reliance and practical knowledge in ensuring safe and effective diving practices.
