Criminal Careers: Understanding Patterns and Influences

Criminal Careers: A Comparative Analysis with Conventional Careers

  • Introduction to Criminal Careers

    • Concept of criminal careers draws parallels with conventional careers.

    • Similarities include beginnings, transitions, and career changes.

  • Structure of Careers

    • Conventional Careers

    • Examples: teacher, electrician, psychologist.

    • Criminal Careers

    • Various types of crimes one can commit similar to job types.

    • Career Switching

    • Transitioning from one job type to another is common.

      • Example: A person may switch from teaching to police work and then to sales.

    • Offenders also shift between different types of crime, showing versatility in their criminal behavior.

  • Periods of Offending

    • Offenders can have periods of non-offending as well as frequent offending.

    • Variability in Offending Rates

    • The frequency and seriousness of criminal acts can change significantly over time.

    • Offenders eventually stop offending, akin to retirement in conventional careers.

    • Dynamic Nature of Criminals

    • Criminals should not be viewed as a static group.

    • Individual life trajectories can lead to significant shifts in offending behaviors.

    • Example: A former offender at 17 years old can become a doctor by age 30.

Crime Peaks in Adolescence

  • Exploring Why Crime Peaks during Adolescence

    • Evolutionary Theories

    • Adolescents, particularly young men, may engage in risk-taking behaviors to attract mates.

    • Neuropsychological Perspectives

    • Inadequate maturity of the prefrontal cortex during adolescence contributes to impulsive decision-making.

    • Personality Development

    • Personality traits remain fluid and may not stabilize until mid-twenties.

    • Maturity Gap

    • Cultural and societal perceptions of adolescence create a “vague” adulthood.

      • Example: Adolescents may achieve adult status in some areas (e.g., driving), while remaining treated as children in others (e.g., drinking age).

    • Ambiguity during this developmental phase can lead to increased crime as a form of expression.

    • Transition to Adulthood

    • As individuals assume adult responsibilities (jobs, partnerships), rates of criminal behavior generally decrease.

The Dunedin Study

  • Overview of the Dunedin Study

    • Longitudinal study following over 1000 individuals from Dunedin, New Zealand since 1972.

    • Regular assessments of health and social factors by researchers.

  • Terry Moffitt's Contribution to the Study

    • Joined in 1985, analyzing the data with a focus on crime.

    • Identified two distinct pathways of offenders:

    • Life Course Persistent Offenders

    • Adolescent Limited Offenders

Life Course Persistent Offenders

  • Key Characteristics

    • Start committing offenses at an early age (age 5-6).

    • Early signs of antisocial behavior (e.g., attention deficit problems, school truancy, petty crime).

    • Continual offending through to later life (into their sixties/seventies).

    • Represent about 5% of the population but account for approximately 50% of all crime.

    • Frequent diagnoses of psychological disorders, particularly antisocial personality disorder.

    • Cumulative Effects of Interaction

    • Negative reactions from parents and educators may reinforce their antisocial behavior.

Adolescent Limited Offenders

  • Description of Offending Pattern

    • Typically cannot be predicted from childhood behaviors.

    • Offending behavior is often brief and sporadic (typically at ages 15-16).

    • Generally engages in lower levels of crime.

  • Influences on Behavior

    • Significant impact of opportunity and peer dynamics.

    • Tendency to co-offend, and may model behavior after life course persistent offenders perceived as role models during adolescence.
