Final answer:
Individuals with Dark Triad traits may engage in risky behaviors such as seeking multiple sex partners, exhibit aggressive behaviors to achieve goals, have unstable self-concepts but similar levels of self-esteem to others, and research shows males tend to score higher on Dark Triad measures, especially psychopathy and Machiavellianism.
Step-by-step explanation:
Individuals who exhibit Dark Triad traits, which include narcissism, Machiavellianism, and psychopathy, tend to display several distinct behavioral patterns. First, they may indeed seek out multiple, casual sex partners as part of a higher tendency for engaging in risk-taking behaviors and desire for personal gratification. Second, these individuals can act aggressively to get what they want when someone obstructs their goals. Third, while their self-esteem levels may not differ significantly from others, those with high Dark Triad scores often exhibit an unstable self-concept. Finally, research has indicated that males generally score higher than females on Dark Triad measures, particularly in the areas of psychopathy and Machiavellianism.
