In this episode, we explore how human perception and assumptions can lead to critical errors, using real-world examples like the tragic 1994 friendly fire incident where two US helicopters were mistaken for enemy aircraft. These events highlight the dangers of "believing is seeing" and how expectations can shape our decisions under pressure. We connect these lessons to diving, where incomplete information and mental shortcuts can result in serious incidents. Learn how to reduce errors by validating assumptions, improving communication, and fostering shared mental models, helping to enhance safety and teamwork in high-risk environments.
