Abstract
Human factors remain the predominant cause of aviation accidents globally, yet the specific role of subclinical personality traits and cognitive biases in shaping safety decision-making among student pilots remains underexplored. This mixed-methods study examined the influence of narcissism (X1) and overconfidence bias (X2) on safety decision-making (Y1) among commercial pilot students in Thailand, within the theoretical context of Bounded Rationality and hazardous aviation attitudes. Using an explanatory sequential design, quantitative data were collected from 274 student pilots via a structured questionnaire incorporating the Narcissistic Personality Inventory-16 (NPI-16), a knowledge-confidence calibration measure, and hazardous scenario-based decision items. Hypotheses were tested using simple linear regression analysis and hierarchical moderated regression analysis. All four hypotheses were supported. Narcissism was a strong and significant positive predictor of safety decision-making quality (β = 0.564, p < .001, R² = .318) and positively predicted overconfidence (β = 0.148, p = .014). Overconfidence was a strong predictor of hazardous decision-making, explaining 24.0% of the variance (β = 0.490, p < .001). Critically, narcissism acted as a synergistic moderator: the narcissism × overconfidence interaction accounted for an additional 14.1% of explained variance, bringing the total model fit to R² = .628. Qualitative interviews with senior flight instructors identified three amplifying mechanisms: Feedback Resistance, Mission-Oriented Fixation, and the Halo Effect of Early Success. These findings provide empirical grounds for integrating personality-informed psychological screening and ego-management modules into Crew Resource Management training curricula.
