Criminology Study Guide

📖 Core Concepts Criminology – interdisciplinary study of crime, deviance, law‑enforcement, and punishment drawing on sociology, psychology, law, economics, biology, etc. Classical School – crime is a rational choice; punishment must be certain, swift, public, and proportionate to deter. Positivist School – behavior is shaped by internal (biological, psychological) and external (social) factors beyond full personal control. Differential Association – people learn criminal values and techniques through interaction with deviant peers. Social Disorganization – community instability (poverty, turnover) weakens informal controls, raising crime rates. Strain / Anomie – gap between culturally prescribed goals and accessible means creates pressure that may lead to crime. Social Control (Bond) Theory – strong attachments, commitments, beliefs, and involvement lower the likelihood of offending. Labeling Theory – societal labels can push a person into a criminal identity and continued offending. Rational Choice Theory – offenders weigh costs (risk, punishment) vs. benefits before acting. Routine Activity Theory – crime occurs when a motivated offender, suitable target, and lack of capable guardian converge. Relative Deprivation – perceived inequality compared to peers fuels resentment and can motivate crime. Public Criminology – translating research for non‑academic audiences to inform policy and public opinion. --- 📌 Must Remember Four Classical Punishment Principles: public, prompt, necessary, minimum required for deterrence. Four Bonds (Hirschi): attachment, belief, commitment, involvement. Elements of Routine Activity: motivated offender + suitable target + absence of capable guardian (± place manager). Strain Sources (Agnew): failure to achieve goals, loss of valued stimuli, presentation of negative stimuli. Key Positivist Sub‑schools: biological (Lombroso), psychological (personality traits), social (poverty, education). Differential Association Variables: frequency, duration, priority, intensity of associations. Labeling Consequence: “self‑fulfilling prophecy” – labeled individuals adopt the criminal role. Public Criminology Goal: move research out of the academy to affect real‑world policy. --- 🔄 Key Processes Classical Deterrence Cycle Crime → Potential offender evaluates pleasure vs. pain → If perceived cost > benefit, crime is deterred. Differential Association Learning Interaction → Internalization of definitions favorable to law violation → Increased likelihood of offending. Social Disorganization Impact Poverty & turnover → Weak institutions → Reduced informal social control → Higher crime. Strain to Crime Pathway Goal–means gap → Strain → Adoption of illegitimate means (innovation) or retreat (withdrawal). Routine Activity Convergence Identify offender, target, and guardian → If all present, crime opportunity materializes. --- 🔍 Key Comparisons Classical vs. Positivist Agency: Classical assumes free rational choice; Positivist stresses determinism. Policy focus: Classical → deterrence via punishment; Positivist → treatment, rehabilitation. Biological Positivism vs. Psychological Positivism Focus: Physical traits (e.g., Lombroso’s atavism) vs. personality/mental traits (neuroticism, aggression). Strain Theory vs. Relative Deprivation Source of pressure: Strain = structural goal‑means mismatch; Relative deprivation = perceived inequality to peers. Labeling Theory vs. Social Control Theory Emphasis: External label shaping identity vs. internal bonds preventing deviance. --- ⚠️ Common Misunderstandings “Classical = harsh punishment.” – Classical actually stresses proportional, certain, swift punishment, not severity for its own sake. “Positivism denies free will completely.” – It argues that many factors constrain choice; it does not claim absolute determinism. “All crime is caused by poverty.” – Poverty is a risk factor (social positivism) but not a sole cause; other theories highlight culture, strain, opportunity, etc. “Labeling only affects the labeled individual.” – It also reshapes how others treat the person, reinforcing the deviant role. --- 🧠 Mental Models / Intuition Cost‑Benefit Scale: Imagine a balance—add “risk” and “severity” on the left, “reward” on the right. When the left outweighs the right, rational offenders pause. Neighborhood Health Meter: Picture a community as a “health bar” that depletes with poverty, turnover, and weak institutions; lower the bar, higher the crime risk. Learning Funnel: Think of social learning as a funnel—wide exposure to peers narrows into internalized criminal definitions. --- 🚩 Exceptions & Edge Cases Routine Activity Theory: Even with a capable guardian, highly motivated offenders may still act if the target is especially valuable (e.g., high‑value theft). Classical Deterrence: Over‑severe punishments can backfire, increasing defiance rather than deterrence. Labeling Theory: Some individuals resist the label and pursue “desistance” despite societal labeling. --- 📍 When to Use Which Assessing offender motivation: Use Rational Choice when cost‑benefit calculations are evident (e.g., white‑collar fraud). Explaining community crime spikes: Apply Social Disorganization or Routine Activity to analyze environmental conditions. Understanding youth delinquency: Choose Differential Association or Sub‑cultural Theories (Cohen, Cloward‑Ohlin). Designing interventions: Deterrence‑focused: Classical principles → stricter, certain penalties. Rehabilitation‑focused: Positivist insights → treatment for mental health, education, employment programs. --- 👀 Patterns to Recognize “Motivated offender + easy target + no guardian” appears repeatedly in crime‑scene descriptions → Routine Activity cue. References to “poverty, unemployment, turnover” signal a social disorganization context. Mentions of “goal‑means mismatch” point to strain or anomie explanations. Use of terms like “learning,” “definitions,” “association” indicates differential association processes. --- 🗂️ Exam Traps Distractor: “Punishment must be severe to deter” – Classical theory actually stresses certainty and swiftness, not severity. Distractor: “Lombroso proved biology determines crime” – His work lacked controls and is now rejected. Distractor: “Labeling theory says crime is caused by poverty” – Labeling focuses on social reaction, not economic conditions. Distractor: “Routine Activity Theory ignores the offender’s intent” – The theory assumes a motivated offender, but intent is still a factor. Distractor: “Strain theory only applies to financial goals” – Agnew expanded strain to non‑financial sources (e.g., abuse, loss). ---
