Relationship between Dark Triad Traits, Cognitive Rigidity and Aggression among Young Adults

People who show traits like narcissism, Machiavellianism or psychopathy often struggle in relationships and act more aggressively. Still, little is known about how their thinking styles play a role. When someone finds it hard to shift viewpoints or consider new ideas, what some call rigid thinking, it might fuel hostile reactions, especially in those with such traits. With a sample size of 200 participants, comprising 100 females and 100 males, this study looks into the relationship between Dark triad traits, cognitive rigidity, and aggression in young adults. This research looked at how these three factors connect using data from 200 young adults between 18-30 years. Dark Triad traits were measured using SDT-27. Cognitive rigidity was assessed using the Cognitive flexibility inventory (CFI-20) assuming that lower flexibility scores show higher rigidity. The Reactive–Proactive Aggression Questionnaire (RPQ) gave insight into aggressive tendencies. This study uses statistical methods, including Pearson’s correlation and multiple regression methods. Strong links showed up between darker personality features, inflexible thought, and acts of aggression. Thinking in rigid ways stood out as closely tied to aggressive responses. That mental stiffness helped explain why certain personalities act more aggressively. Young adults who have rigid thinking patterns often show it in their personality which reflect harmful actions.
