SH286: The Shortcut That Gets You Home — and the One That Doesn't

SH286: The Shortcut That Gets You Home — and the One That Doesn't

Divers make many decisions quickly, often without realising it, by using heuristics—mental shortcuts that help us act fast when time and information are limited. These shortcuts are essential and often effective, especially with experience, but they can also lead to predictable errors called biases when used in the wrong situation. Common examples include relying too much on recent experience, sticking to an original plan despite changing conditions, or only noticing information that supports what we already believe. In diving, where conditions vary and feedback is often limited, these biases can quietly increase risk. The key is not to avoid intuition, but to understand when it might be misleading and to slow down when needed. Tools like checklists, realistic training, and open team communication help balance fast thinking with more careful decision-making, improving safety and helping divers make better choices underwater.
