Dark Personality Traits and the Big Five Personality Traits of Fathers in Relation to Sons’ Self-Confidence, Self-Esteem, and Attachment Style: The Moderating Role of Fathers’ Life Strategy and Reproductive Value
This study of 200 male participants reveals that fathers' personality traits, particularly neuroticism and conscientiousness, and their supportive behaviors significantly influence sons' self-esteem and attachment styles, with these relationships further moderated by the fathers' mate value.

The bond between a father and his son is one of the most powerful relationships in human life, shaping how a boy sees himself and how he connects with others. For decades, psychologists have understood that a father's character matters, but they have often looked at this through a narrow lens, focusing on whether a father is present or absent, or whether he is kind or harsh. More recently, scientists have begun to ask deeper questions about the specific personality traits a father carries. They look at the "Big Five," a set of five broad personality categories that describe how people generally think and act, ranging from how organized they are to how emotionally stable they feel. They also examine the "Dark Triad," a cluster of three traits often associated with manipulation, grandiosity, and a lack of empathy. Beyond these personality maps, evolutionary science suggests that a father's life strategy—whether he focuses on long-term family building or short-term gains—and his perceived value as a partner might change how his personality affects his child. Understanding these layers is crucial because the way a son internalizes his father's character can influence his self-worth and his ability to form secure, trusting relationships throughout his life.
A new study conducted by researchers at Goldsmiths, University of London, and the University of Bucharest brings these different threads together to see how they weave into the lives of adult sons. The researchers asked 200 men, with an average age of nearly 28, to look back at their fathers and describe their personalities, their behaviors, and the quality of their relationship. The sons also rated their own self-esteem, their confidence, and how securely they feel attached to others. The goal was to see if specific traits in the father predicted specific outcomes in the son, and whether the father's life strategy or his attractiveness as a partner changed the strength of these connections. The study did not involve watching families in real time or conducting experiments; instead, it relied on the sons' own memories and perceptions to build a picture of how these dynamics play out.
The results painted a clear picture of how a father's personality leaves a mark. When a father scored high on traits like neuroticism, meaning he was prone to anxiety and emotional instability, his sons were more likely to report feeling insecure in their relationships, often worrying about being abandoned or pushing people away. Similarly, when a father displayed traits associated with the "Dark Triad," such as being manipulative or lacking a conscience, his sons tended to have lower self-esteem and more anxious feelings about their relationships. However, the story was not entirely negative. Fathers who were conscientious—organized, reliable, and disciplined—had sons with higher self-esteem and fewer fears of intimacy. Perhaps most importantly, the study found that the day-to-day behavior of the father mattered just as much as his personality. Sons who described their fathers as supportive, warm, and engaged reported higher self-esteem and felt much more secure in their relationships, regardless of the father's specific personality quirks.
One of the most surprising findings involved narcissism, a trait often linked to self-centeredness. While the researchers expected that a narcissistic father would create distance and insecurity in his son, the data showed the opposite. Sons of fathers with higher levels of narcissism actually reported lower levels of avoidant attachment, meaning they were less likely to shut down emotionally or avoid closeness. The researchers suggest this might be because some aspects of narcissism, such as confidence and social boldness, could encourage a son to engage more with others, even if the father's overall behavior is flawed. This unexpected result highlights that personality is complex; a single trait does not always lead to a single outcome, and different parts of a father's character can pull in different directions.
The study also tested whether a father's "mate value"—how attractive or desirable he is seen as a partner—and his life strategy acted as a background factor that changed these relationships. The researchers found that a father's life strategy, whether he was focused on long-term stability or short-term risks, did not significantly change how his personality affected his son. However, his mate value did play a role. Specifically, the positive effect of a father's conscientiousness on his son's security was strongest when the father's mate value was lower. In other words, when a father was highly organized and reliable, it helped his son feel more secure in relationships, but this benefit was even more pronounced if the father was not seen as particularly high in mate value. When the father's mate value was high, the link between his reliability and his son's security was still present but slightly weaker. This suggests that the context of a father's overall standing in the social world can subtly shift how his personal traits are experienced by his child.
Ultimately, this research suggests that the father-son relationship is a complex tapestry woven from personality, behavior, and evolutionary context. It is not just about whether a father is "good" or "bad," but about how specific traits like reliability, emotional stability, and warmth interact with the son's own development. The study confirms that supportive behavior is a powerful force for building a son's confidence and security, while certain personality traits can introduce insecurity. It also reveals that the influence of a father is not a simple one-way street; it is moderated by the broader context of his life and his perceived value in the world. By looking at these factors together, scientists are beginning to understand the nuanced ways in which a father's character shapes the man his son becomes, offering a clearer view of the roots of self-esteem and attachment.
