Evidence for an aggressive (and delinquent) personality
The British Journal of Social Psychology
|March 1, 1987
Summary
Aggressive personality traits are identifiable through aggregated behavioral measures, linking them to delinquency and moderate heritability. Consistent patterns emerge when analyzing sufficient data, revealing underlying behavioral dimensions.
Area of Science:
- Psychology
- Behavioral Genetics
Background:
- Personality traits, such as aggression, can be difficult to identify due to variability in individual behaviors.
- Previous research may have underestimated the consistency of aggressive personality due to insufficient data aggregation.
Purpose of the Study:
- To demonstrate the existence of an aggressive personality through aggregated behavioral measures.
- To associate aggressive personality patterns with delinquent behavior and heritability.
Main Methods:
- Utilizing sufficiently aggregated measures to average out idiosyncratic variance in behavioral observations.
- Analyzing a large enough sampling of behavioral exemplars to identify consistent patterns.
Main Results:
- Consistent patterns of individual and group differences in aggression were found.
- These patterns were associated with delinquent behavior.
- Aggression and its associated behaviors were found to be moderately heritable.
Conclusions:
- An aggressive personality can be reliably identified using aggregated behavioral data.
- Aggressive personality is linked to delinquency and exhibits moderate heritability.
- The principle of data aggregation is crucial for understanding underlying behavioral dimensions.

01:47Aggression
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for hire...
02:04Bullying
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
01:28Adler's Individual Psychology
Alfred Adler, a prominent figure in psychology, founded the school of individual psychology. In contrast to Freud's emphasis on sexual or aggressive motives, Adler suggested that individuals are primarily motivated by their purposes and goals. He believed that people strive for perfection rather than pleasure. Adler argued that individuals could creatively act upon their genetic inheritance and environmental experiences to shape their own lives, emphasizing conscious motivation over unconscious...

Antisocial personality disorder is a chronic mental health condition characterized by persistent patterns of disregard for the rights and well-being of others. Individuals with antisocial personality disorder exhibit behaviors that include deceitfulness, impulsivity, irresponsibility, aggression, and a profound lack of empathy. These traits often manifest early in life and persist into adulthood, leading to significant personal, social, and legal consequences.

01:28Conduct Disorder
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
01:29Dark Triad and Person Perception
Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et al. (2014) explored...
