Final answer:
The dark-side personality trait characterized by an unhealthy distrust and vigilance for disloyalty in others is paranoid.
Step-by-step explanation:
The dark-side personality trait defined by an unhealthy mistrust of others, constantly questioning motives and integrity, and being vigilant for signs of disloyalty is paranoid. Leaders with this trait exhibit an extreme level of skepticism about the loyalty and trustworthiness of their colleagues and subordinates,
which can lead to toxic work environments and dysfunctional team dynamics. This is in contrast to traits such as Machiavellianism, which is characterized by manipulation and exploitation of others, Avoidance, which deals with shying away from leadership and responsibility, and Authoritarianism,
which involves strict adherence to rules, control, and a preference for order and hierarchy. Paranoid leadership can undermine the confidence and morale of followers, impede open communication, and create an atmosphere of fear and uncertainty.
