Antisocial behavior, which includes actions that harm others or violate their rights, is a pervasive issue often linked to sociopathy. This behavior can become a lifestyle for some individuals. While there is a belief that such behaviors are learned, extensive research indicates that genetic predispositions play a significant role in this development, which typically begins in childhood and adolescence. A prominent study tracking over 1,000 individuals born in Dunedin, New Zealand, in 1972 provides valuable insights into this subject. This article explores several key questions that emerged from the study:
- Do men exhibit more violence than women?
- Is antisocial behavior consistent in individuals over time?
- Is the stability of antisocial behavior the same for both genders?
- What age do delinquency and conduct disorders typically begin in males and females?
Are Men More Violent Than Women?
Numerous studies have shown that females tend to be less violent than their male counterparts. This observation has often been interpreted as a fundamental difference in the capacity or motivation for violence between the sexes. However, findings from the Dunedin study reveal that males score significantly higher than females on various measures of physical aggression. This trend holds true across all ages up to 21, with males being nearly five times more likely to be convicted of violent crimes by that age.
The one significant exception to this pattern is seen in cases of intimate partner or family violence. In these contexts, women may exhibit equal or even greater levels of violence than men, as the need for control and dominance can manifest in both genders, particularly within familial relationships.
Stability of Antisocial Behavior Over Time
Even in the 1970s, during the peak of situationism in psychology, researchers acknowledged that individual differences in antisocial behavior (ASB) tend to be stable. Certain individuals are naturally more antisocial, and this tendency often persists throughout their development. Analyzing the stability of ASB in the Dunedin study shows that both boys and girls maintain their relative positions in antisocial behaviors as they grow, based on various assessments from parents, teachers, peers, and self-reports.
Conduct Disorder and Gender Differences
While both genders may retain their rank in terms of antisocial behavior, females are less likely to exhibit extreme behaviors that meet the criteria for a conduct disorder diagnosis. The continuity of this disorder is not equal between the sexes; males consistently show a higher degree of stability. About 50% of males diagnosed with conduct disorder maintain their condition, while only 16% of females do the same. This discrepancy suggests that while rank in antisocial behavior remains stable, the clinical manifestation of conduct disorders is less stable in females.
Age of Onset for Antisocial Behavior
The age at which antisocial behavior begins can vary based on the source of the data. Self-reported data often indicates that the onset of antisocial behavior occurs around the ages of 12 to 14 for both genders, although official convictions may lag by several years. At every age, a higher number of males initiate theft and violence compared to females.
Conclusion
The exploration of gender differences in antisocial behavior reveals significant insights into the dynamics of violence and conduct disorders. Understanding these differences is crucial for developing effective strategies for prevention and intervention.
