A study by psychology researchers has found that leadership often attracts 'dark' personality traits, such as psychopathy, Machiavellianism, and narcissism. The researchers found that these traits can influence individuals' interest in pursuing certain types of career and leadership styles. The study also found that people with high levels of psychopathic traits tend to live in solitary work environments, likely due to their low motivation for social affiliation and interaction. Those with more Machiaevian personality traits gravitated to leadership roles. The findings suggest that an awareness of leaders' and potential leaders’ personality traits is crucial for shaping leadership teams and choosing who to be in management positions. However, it also highlights the potential for aggressive leadership styles to lead to mediocre team performance.
