摘要

Personality traits play a critical role in law enforcement, influencing decision-making, ethical behavior, and interpersonal relationships. This study examined the prevalence of Dark Triad traits (psychopathy, Machiavellianism, and narcissism) and Big Five personality traits among law enforcement officers from two metropolitan agencies in the United States. Using validated measures, including the Ten-Item Personality Inventory (TIPI) and the Short Dark Triad (SD3), officers were compared to normative personality data. Findings indicated that officers exhibited lower levels of Machiavellianism and psychopathy, with slightly elevated narcissism compared to normative data. Within the Big Five framework, officers demonstrated higher conscientiousness and emotional stability but lower agreeableness and openness to experience. Extraversion did not differ significantly from the general population. A secondary analysis revealed that tenure in law enforcement was associated with lower agreeableness and a marginal increase in Machiavellianism, suggesting potential occupational socialization effects. These findings challenge the notion of a singular “police personality,” instead highlighting a complex interplay between individual predispositions and professional experiences. Implications for recruitment, training, and leadership development are discussed, emphasizing the importance of fostering emotional intelligence and ethical decision-making to enhance officer effectiveness and community trust. Future research should explore longitudinal personality development in law enforcement and the impact of targeted interventions on maladaptive traits.
