The narcissistic traits of police officers aged 17 to 78 in the United States affect American citizens in various degrees. Improvements made to pre-employment psychological evaluations, such as the Minnesota Multiphasic Personality Inventory (MMPI-2), the L (Lie) Scale, and the Narcissistic Personality Inventory (NPI), may detect and screen out police officer candidates with underlying Narcissistic Personality Disorder (NPD). It is important that candidates with NPD be screened out as, if they become officers, they may commit acts of police misconduct, which greatly affect the safety and trust of the American people.
