Representativeness Bias: Does a Near-miss make a person more cautious or less cautious the next time?
Representativeness Bias: Near-Misses: Mars Rover Operators “… categorized the current [similar] circumstances as beingsurvivable”

Flipping the Switch: Theory of 10/80/10: Most will be stunned Temporary effect Seek calmness Plan for emergencies
Experience: • Novices have difficulty gathering, integrating, and understanding informational cues • Improves knowledge of performance needed • Develops a better understanding of how stressors, biases, and emotions impact decisions
Education: “You rarely get someone to jump a skill level by teaching more facts and rules…. we cannot expect to grow instant experts” - Williams
Training: “familiarity with the criterion environment…. effective task performance under stress conditions” - Driskell and Johnston
Experience: Variety of experience is more important than simple years of service.
Mentoring: “to enhance the development of perceptual expertise in the trainees” - Klein Train Your Mentors:
Leadership: “…individuals respond well to a leader, however, if leadership is lacking, people tend to become confused.” - Kowalski-Trakofler and Vaught. MS Estonia
Training and Experience: Risk perception can be modified, Stressors can be mitigated, Biases can be minimized, Emotionscan be mastered.
