Red Flag Behavioral Checklist

Understanding precursors to violence with educational context

Important Educational Disclaimer

This checklist provides an overview of behavioral patterns and indicators often studied in forensic psychology as potential precursors or correlates to violent and serial offending.

It is crucial to understand that the presence of one or more of these behaviors does NOT automatically indicate future violence, but rather serves as a guide for further assessment and understanding within a broader psychological context.

This tool is for educational purposes only and should not be used for diagnosis or prediction of individual behavior.

Early Warning Signs & Developmental Factors
Often observed in childhood or adolescence, historically linked to later violent behavior

The MacDonald Triad

A set of three behavioral characteristics first proposed by J.M. MacDonald in 1963. While controversial and not a definitive predictor, it remains frequently discussed.

  • Enuresis (Persistent Bedwetting): Beyond age 5-6, particularly when associated with psychological distress or abuse
  • Zoophilia (Animal Cruelty): Deliberate and repeated acts of torture or killing of animals, often escalating in severity
  • Pyromania (Fire-Setting): Intentional and repeated fire-setting, often for gratification or to relieve tension

Childhood Trauma & Abuse

A significant history of physical, emotional, or sexual abuse, neglect, or severe family dysfunction

Social Isolation & Poor Peer Relationships

Difficulty forming meaningful connections, being a loner, or experiencing significant bullying

Lack of Empathy & Remorse

An inability to understand or share the feelings of others, and a lack of guilt or regret for harmful actions

Fascination with Violence & Death

Preoccupation with violent media, weapons, or morbid topics beyond typical curiosity

Escalation Patterns & Behavioral Indicators
Behaviors that may indicate progression towards more severe or organized offending

Escalation of Offenses

A history of increasingly severe antisocial or criminal acts, starting from minor infractions and progressing to more serious crimes

Fantasy Life

An intense and often elaborate fantasy life, particularly involving themes of power, control, violence, or sexual deviance, which may serve as a rehearsal for future acts

Stalking Behavior

Persistent and unwanted attention, harassment, or surveillance of an individual, often preceding direct violence

Paraphilias

Atypical sexual interests that may involve non-consenting individuals, pain, or humiliation, which can be acted out in violent crimes

Substance Abuse

Chronic use of drugs or alcohol, which can lower inhibitions and exacerbate aggressive tendencies

Poor Impulse Control

Difficulty regulating emotions and behaviors, leading to impulsive and often destructive actions
