UFS CRIM2614 Exam Notes: Etiology of Crime Study Guide

These exam notes provide a structured, exam-focused guide to the etiology of crime as studied in UFS CRIM2614 at the University of the Free State. The emphasis is on understanding how crime is explained through major criminological theories, how those theories compare, and how they are applied to real-world offending patterns. The guide is written for revision, with clear definitions, key debates, examples, and the kinds of links between theory and practice that often appear in university assessments.

1. What “Etiology of Crime” Means in Criminology

The term etiology of crime refers to the causes, origins, and developmental pathways of criminal behaviour. In criminology, this does not mean that there is one single cause of crime. Instead, the study of etiology explores why some people offend, why some offend repeatedly, why crime varies across places and time periods, and why different forms of crime require different explanations. In exam terms, the core issue is not simply “what is crime?” but rather “what factors produce criminal behaviour, and through what mechanisms?”

Why this topic matters in CRIM2614

The etiology of crime is foundational because almost every other criminological question depends on it. If crime is caused mainly by biology, interventions will focus on early identification and treatment. If crime is caused mainly by social disorganization, then community development and structural reform become more important. If crime is the result of rational choice, then deterrence and situational prevention matter more. Theories of etiology therefore shape criminal justice policy, policing, corrections, prevention, and rehabilitation.

In a South African university context, this topic is especially important because crime is often discussed in relation to:

• inequality and poverty,
• urban violence,
• gang activity,
• substance abuse,
• family breakdown,
• youth unemployment,
• historical and structural disadvantage,
• and the effectiveness of criminal justice responses.

Core ways criminologists explain crime

Most etiological theories fall into a few broad categories:

1. Biological explanations
   Crime is linked to genetic, neurological, hormonal, or physiological factors.

2. Psychological explanations
   Crime is linked to personality, cognition, learning, self-control, or mental processes.

3. Sociological explanations
   Crime is linked to social environment, family, peers, community structure, culture, and social inequality.

4. Integrated or developmental explanations
   Crime emerges from interacting biological, psychological, and social factors over time.

These categories are not mutually exclusive. A modern criminologist often argues that criminal behaviour is multifactorial, meaning that several causes combine and interact. For that reason, exam answers should avoid oversimplified claims such as “poverty causes crime” or “bad people commit crime.” Strong answers show that crime is shaped by both individual-level and structural-level factors.

Crime as a process, not only an event

An important exam insight is that criminal behaviour is often best understood as a process rather than a single decision. A person may begin with early childhood adversity, develop weak attachment to caregivers, associate with delinquent peers, experience school failure, abuse substances, and then progress to repeated offending. Etiological theories differ in how they describe this pathway, but many modern theories agree that crime often develops over time.

This process view is especially important in life-course criminology, which studies how offending begins, persists, and ends across stages of life. It asks questions such as:

• Why do some children show antisocial behaviour early?
• Why do some adolescents offend but later desist?
• Why do a small number of offenders commit a large amount of crime?
• Why do offenders age out of crime?

Key concepts you should know

• Etiology: the study of causes or origins.
• Criminal behaviour: actions that violate criminal law.
• Antisocial behaviour: behaviour that harms, defies, or disregards others and social norms.
• Risk factor: a condition that increases the probability of offending.
• Protective factor: a condition that reduces the probability of offending.
• Correlation vs causation: two things may be related without one causing the other.
• Multifactorial causation: crime results from several interacting influences.
• Onset: the beginning of offending.
• Persistence: continued offending over time.
• Desistance: stopping criminal behaviour.

Exam tip

When writing about etiology, always distinguish between:

• individual explanation and social explanation,
• background factors and immediate triggers,
• risk factors and causal factors,
• short-term acts and long-term pathways.

A strong essay usually explains not just what a theory says, but also how it explains crime and why it is useful or limited.

2. Biological and Biosocial Theories of Crime

Biological criminology argues that some aspects of criminal behaviour can be traced to physical constitution, heredity, brain functioning, hormones, and temperament. Older versions of biological theory were often deterministic and sometimes racist or class-biased. Modern biosocial approaches are more careful: they do not claim that biology alone causes crime, but rather that biological factors may interact with environment, family conditions, trauma, and socialization.

2.1 Lombroso and the early biological school

One of the earliest biological theorists was Cesare Lombroso, often called the father of criminology. He argued that criminals were atavistic beings, meaning they were evolutionary throwbacks who displayed physical stigmata such as asymmetrical faces, large jaws, and other bodily traits. This approach is now considered scientifically weak and historically problematic because it assumed that criminality could be seen on the body and often ignored social conditions.

Despite its flaws, Lombroso is important in criminology history because he shifted attention away from purely moral explanations and toward empirical observation. His work helped establish the idea that crime could be studied scientifically. However, his theory failed because:

• it overgeneralized from limited samples,
• it confused correlation with causation,
• it ignored social context,
• and it reinforced stigmatizing assumptions.

2.2 Genetic and hereditary influences

Modern biological research has examined whether criminal tendencies may be partly inherited. This does not mean that crime is “in the genes” in a simple sense. Instead, genetic influences may affect:

• impulsivity,
• sensation seeking,
• aggression,
• low fearfulness,
• and poor emotional regulation.

Twin and adoption studies have often found some heritable component to antisocial behaviour. The logic is that if identical twins resemble each other more in offending than fraternal twins, genetics may play a role. But even where heritability exists, it does not mean destiny. Genes may influence vulnerability, but environment shapes whether that vulnerability becomes criminal behaviour.

A useful exam point is that genes may affect predispositions, not direct actions. For example, a child may inherit a tendency toward impulsivity, but whether that tendency becomes persistent offending depends on parenting, school environment, peer influence, and opportunity structures.

2.3 Brain structure, brain function, and neurocriminology

Neurocriminology examines how the brain relates to antisocial and criminal behaviour. Research has focused on areas involved in:

• decision-making,
• impulse control,
• moral reasoning,
• empathy,
• and emotion regulation.

Important brain regions include the prefrontal cortex, which is associated with planning, judgment, and self-control, and the amygdala, which is linked to fear and emotional processing. If these systems function poorly, a person may struggle to assess consequences, regulate anger, or respond to social cues.

Brain injury, prenatal exposure to toxins, developmental disorders, and neurological impairments can all affect behaviour. For example, early childhood head trauma or prenatal alcohol exposure may increase the likelihood of later behavioural problems. This does not mean that every person with a neurological difference will offend. Rather, the risk is increased when neurological vulnerability combines with abuse, neglect, poor supervision, or delinquent peer groups.

2.4 Hormones, arousal, and temperament

Some biological theories focus on hormones such as testosterone, which has been associated with dominance-seeking and aggression in some contexts. However, the relationship is complex and should not be overstated. Hormones do not mechanically produce crime; they may influence aggression or competitiveness, especially when reinforced by social context.

Temperament is also important. Some children are born with more difficult temperaments, higher reactivity, or lower inhibition. If such children receive harsh, inconsistent parenting, they may develop externalizing behaviours such as defiance, rule-breaking, and aggression. In this sense, biology matters, but it acts through interaction with environment.

2.5 Biosocial theory and gene-environment interaction

The strongest modern biological perspectives are biosocial. These theories argue that criminal behaviour emerges from the interaction between biological predispositions and environmental conditions. A child may inherit impulsivity, but whether that child develops crime-related behaviour depends on:

• parental supervision,
• school discipline,
• exposure to violence,
• substance use,
• peer groups,
• neighbourhood disadvantage,
• and access to support.

This interaction approach is much more convincing than older biological determinism. It explains why the same biological trait may produce different outcomes in different environments. A supportive home, stable school, and prosocial peers can reduce risk, while abuse, poverty, and violence can amplify it.

2.6 Strengths and limitations of biological explanations

Strengths

• They remind criminologists that behaviour has a human organism behind it.
• They help explain why some people are more vulnerable to impulsivity, aggression, or low self-control.
• They support early intervention, especially in childhood.
• They are consistent with research showing that antisocial behaviour has some stability over time.

Limitations

• They can become deterministic if presented too strongly.
• They often neglect structural inequality and social context.
• They may stigmatize people as biologically defective.
• Biological factors rarely explain the full picture on their own.

Exam-relevant synthesis

In an essay, a balanced biological answer should say that biological factors can influence offending through:

1. predisposition,
2. impulse control,
3. emotional regulation,
4. stress sensitivity,
5. and interaction with social conditions.

Then you should note that modern criminology rejects the idea that biology alone causes crime. Crime is more accurately understood as a product of biological susceptibility plus social experience.

3. Psychological Theories of Crime

Psychological theories focus on the mind, personality, learning, cognition, and emotional development of the offender. Compared with biological theories, psychological theories explain crime less through physical traits and more through how a person thinks, feels, learns, and relates to others. These theories are central to criminology because many offending patterns involve decision-making, self-control, hostility, moral reasoning, and habits learned over time.

3.1 Psychodynamic theory

Psychodynamic theory is associated with Sigmund Freud and later thinkers. It suggests that personality is shaped by unconscious conflicts among the id, ego, and superego.

• The id seeks immediate gratification.
• The ego mediates between impulses and reality.
• The superego internalizes moral rules.

From this perspective, criminal behaviour may result from an underdeveloped superego, unresolved childhood conflict, or weak emotional regulation. A person who never internalized strong moral restraint may be more likely to act impulsively or aggressively.

Although psychodynamic theory is not commonly used alone in contemporary criminology, it remains useful because it highlights the role of early childhood experiences, attachment, and emotional development. Harsh punishment, neglect, inconsistent parenting, and trauma may distort personality formation and create vulnerability to antisocial behaviour.

3.2 Personality theories

Personality theories argue that some individuals have traits that increase the likelihood of offending. Traits commonly linked to crime include:

• impulsivity,
• sensation seeking,
• aggression,
• low empathy,
• low guilt,
• irritability,
• and risk taking.

A classic idea is that chronic offenders often display a more persistent antisocial personality pattern. However, traits do not directly cause crime unless they are expressed in particular environments. A person with strong sensation seeking may become an athlete, entrepreneur, or offender depending on opportunity and social learning.

One of the most useful exam distinctions is between trait and behaviour:

• A trait is a stable tendency.
• Behaviour is the actual action in a specific context.

A trait like impulsivity increases risk, but it does not guarantee criminal conduct.

3.3 Cognitive theories

Cognitive theories examine how offenders think, interpret situations, and make decisions. They ask whether criminal behaviour is linked to:

• poor problem-solving,
• distorted thinking,
• hostile attribution bias,
• immature moral reasoning,
• and faulty decision-making.

A person with hostile attribution bias tends to interpret ambiguous acts as threatening. For example, if someone accidentally bumps into them, they may assume disrespect and retaliate violently. This bias is common in aggressive and violent offenders.

Cognitive theories are especially important because they show that criminals are not always irrational. Some offend because they misread social cues, underestimate consequences, or use self-serving justifications. Others carefully plan offences. Therefore, crime can be both emotional and strategic.

3.4 Moral development and reasoning

Theories of moral development, particularly those associated with Lawrence Kohlberg, suggest that people progress through stages of moral reasoning. At lower stages, behaviour may be governed by punishment and reward; at higher stages, by social rules and abstract ethical principles. Offending may be more likely when moral development is delayed, limited, or shaped by environments that reward rule-breaking.

In exam discussions, it is useful to explain that a person may know a law exists but still not internalize why it matters. Criminal decision-making can therefore involve a gap between legal knowledge and moral commitment.

3.5 Learning theory

Learning theories are among the most important psychological explanations of crime. They argue that criminal behaviour is learned, not inherited. This includes:

• learning through observation,
• learning through reinforcement,
• learning through association with others,
• and learning criminal definitions and techniques.

Behaviorism and reinforcement

Behaviorist theory suggests that behaviour that is rewarded tends to be repeated. If theft brings money, status, or excitement, and if the offender avoids punishment, the behaviour may be reinforced. Likewise, if aggression leads to respect in a violent peer group, violence becomes more likely.

Social learning theory

Albert Bandura showed that people can learn behaviour by observing others. Children who watch aggression being rewarded may imitate it. In criminology, this means that violent family environments, gangs, or delinquent peer groups can transmit criminal methods and values.

3.6 Self-control theory

One of the most widely discussed psychological explanations is Gottfredson and Hirschi’s self-control theory. It argues that low self-control is the central cause of crime and analogous risky behaviour. People with low self-control tend to be:

• impulsive,
• short-sighted,
• risk-seeking,
• physical,
• insensitive,
• and focused on immediate gratification.

According to this view, self-control is mainly formed early in life through effective parenting. Poor supervision, inconsistency, and failure to teach discipline lead to low self-control, which then increases the probability of crime.

This theory is especially useful for exams because it is simple and broad. However, it is also criticized for oversimplifying crime and underestimating social inequality, opportunity, and changes over the life course.

3.7 Strengths and limitations of psychological theories

Strengths

• They explain individual differences in offending.
• They account for impulsivity, aggression, and distorted thinking.
• They are useful in rehabilitation and behavioural interventions.
• They show how childhood experiences shape later offending.

Limitations

• They may individualize crime too much.
• They can underplay poverty, unemployment, racism, and community context.
• Some theories are difficult to measure directly.
• They may explain the offender’s mindset without explaining why certain groups are disproportionately affected.

Exam-relevant synthesis

Psychological theories are strongest when they are used to explain how offending happens at the level of decision-making, emotion, and learning. A strong exam answer should show that these theories bridge the gap between biology and society by focusing on the person as a thinking, feeling, learning being. In a comprehensive answer, psychological explanations should be combined with family and social context rather than used in isolation.

4. Sociological Theories of Crime

Sociological theories explain crime by focusing on social structure, culture, relationships, and institutions. These approaches are essential because crime is not distributed randomly. It varies by neighbourhood, class, gender, age, and opportunity. Sociological theories ask why some social conditions make crime more likely and why certain communities experience higher rates of violence, theft, or disorder.

4.1 The social environment and crime

Crime often reflects the environment in which people live. Social conditions can shape:

• access to legitimate opportunity,
• exposure to violence,
• peer networks,
• family stress,
• school performance,
• and expectations about the future.

For example, a young person in a stable, well-resourced community may have more access to education, sports, mentorship, and employment pathways. A young person in a violent, under-resourced community may be more exposed to gangs, substance abuse, and survival crime. Sociological theories help explain this uneven distribution.

4.2 Strain theory

Strain theory, associated with Robert Merton, argues that crime occurs when people experience a gap between socially approved goals and the legitimate means to achieve them. If a society strongly values wealth, status, and success but not everyone has equal access to education or employment, some individuals may adapt through crime.

Merton identified several adaptations:

• Conformity: accepting goals and legitimate means.
• Innovation: accepting goals but using illegitimate means.
• Ritualism: rejecting goals but following rules.
• Retreatism: rejecting both goals and means.
• Rebellion: rejecting and replacing existing goals and means.

The most criminogenic adaptation is innovation, where people seek success but use criminal methods such as theft, fraud, or drug dealing.

4.3 General strain theory

Robert Agnew expanded strain theory by arguing that strain is broader than blocked economic opportunity. Crime may result from:

• failure to achieve valued goals,
• loss of positive stimuli,
• and presentation of negative stimuli.

Examples include:

• being bullied,
• parental rejection,
• abuse,
• school failure,
• relationship breakdown,
• unemployment,
• and chronic humiliation.

Agnew also emphasized that strain creates negative emotions such as anger and frustration, which may motivate offending if coping resources are weak. This theory is especially useful because it explains not only property crime, but also violence, substance use, and retaliation.

4.4 Social disorganization theory

Social disorganization theory explains crime through weak community structure. It argues that high-crime areas often experience:

• residential instability,
• poverty,
• ethnic heterogeneity,
• family disruption,
• weak informal control,
• and limited collective efficacy.

Collective efficacy refers to a community’s shared ability to maintain social order and intervene for the common good. When neighbours do not trust one another or feel unable to intervene, crime can flourish.

This theory is valuable because it shows that crime is not only about bad individuals. It is also about neighbourhood conditions that weaken supervision and shared norms. For instance, if a community has high turnover, poor services, and limited social cohesion, it may struggle to control gang activity or youth violence.

4.5 Differential association and social learning

Edwin Sutherland’s differential association theory argues that criminal behaviour is learned through interaction with others. People learn:

• techniques of offending,
• motives,
• justifications,
• and definitions favourable to law violation.

The theory suggests that when pro-criminal definitions outweigh pro-social ones, offending becomes more likely. This is not just about copying behaviour, but about learning the meanings and rationalizations of crime.

Modern social learning theory adds reinforcement, imitation, and anticipated rewards. A youth who joins a gang may learn how to intimidate others, how to obtain money illegally, and how to justify violence as respect protection or survival.

4.6 Labeling theory

Labeling theory argues that crime and deviance are partly created by societal reaction. Once a person is labeled as “criminal” or “delinquent,” they may experience stigma, exclusion, and reduced legitimate opportunities. This can produce a self-fulfilling prophecy where the label becomes part of identity.

Key ideas include:

• primary deviance: initial rule-breaking,
• secondary deviance: further offending resulting from labeling and social reaction.

This theory is especially important in understanding how policing, school discipline, court processes, and prison can sometimes reinforce rather than reduce offending. It does not mean that all offenders are only “labeled” into crime, but it shows that social reaction matters.

4.7 Conflict theory

Conflict theory views crime through the lens of power and inequality. It argues that laws reflect the interests of powerful groups and that crime definitions are shaped by social conflict. Crime is not just a violation of norms; it is also a product of unequal power relations.

This theory is useful when examining:

• selective enforcement,
• criminalization of poverty,
• racialized policing,
• corporate crime,
• and state violence.

Conflict theory reminds criminologists that some harmful acts receive more attention than others. Street crime may be heavily policed while economic and institutional harms may be less visible, even when their social damage is large.

4.8 Feminist criminology

Feminist criminology examines how gender shapes crime, victimization, and control. It criticizes earlier theories for treating male offending as the norm and ignoring women’s experiences. Feminist approaches consider:

• gendered pathways into crime,
• abuse and trauma,
• economic marginalization,
• caregiving responsibilities,
• and the intersection of gender with race and class.

This perspective is important because women’s offending is often linked to survival strategies, coercive relationships, addiction, or exploitation. Feminist criminology also asks how criminal justice systems respond differently to men and women.

4.9 Strengths and limitations of sociological theories

Strengths

• They explain crime distribution across communities and social groups.
• They highlight structural inequality and social context.
• They account for peer influence, family dynamics, and community control.
• They are useful for prevention and policy.

Limitations

• They may overlook individual differences.
• Some versions are difficult to test precisely.
• They may explain where crime happens better than why one person offends.
• They sometimes treat social structure as too dominant and reduce personal agency.

Exam-relevant synthesis

Sociological theories are essential because they show that crime is socially produced, socially learned, and socially responded to. They are especially useful in contexts marked by inequality, weak institutions, and community disorganization. A strong answer should explain how social conditions create risk, how those risks are transmitted through relationships, and how labeling and conflict shape the consequences of offending.

5. Developmental, Integrated, and Exam Application Approaches

Developmental and integrated theories attempt to combine the strengths of biological, psychological, and sociological approaches. Instead of asking whether crime is caused by nature or nurture, these theories ask how influences accumulate across the life course and how different factors interact over time. This is often the most sophisticated way to answer essay questions on etiology because it reflects the complexity of real offending patterns.

5.1 Life-course criminology

Life-course criminology studies criminal behaviour across stages of life, especially childhood, adolescence, early adulthood, and later adulthood. It focuses on:

• onset,
• continuation,
• escalation,
• and desistance.

A key idea is that offending is often developmentally patterned. Some offenders begin early and persist into adulthood, while others offend only during adolescence and then stop. This distinction matters because early starters often have more serious and stable risk factors, while adolescent-limited offenders may be influenced more by peers and social transitions.

5.2 Moffitt’s developmental taxonomy

Terrie Moffitt proposed one of the most influential developmental theories of crime. She distinguished between:

• life-course-persistent offenders: those who begin antisocial behaviour early and continue over time,
• adolescence-limited offenders: those whose offending is mostly confined to adolescence.

Life-course-persistent offending is often linked to neuropsychological deficits, difficult temperament, poor parenting, and cumulative disadvantage. Adolescence-limited offending is often linked to the desire for autonomy, peer influence, and the maturity gap between biological adulthood and social dependence.

This theory is important because it explains why not all offenders are the same. A youth who vandalizes property at age 16 may not be on the same path as a person who has shown persistent aggression since early childhood.

5.3 Integrated theories

Integrated theories combine elements from several traditions. They recognize that:

• biology may shape temperament,
• psychology may shape decision-making,
• and sociology may shape opportunity and learning.

An integrated perspective is often stronger than a single-cause theory because it can explain why similar risk factors may produce different outcomes. For example:

• a child with low self-control may never offend if raised in a supportive environment,
• a socially disadvantaged youth may not offend if attached to strong prosocial institutions,
• and a person may offend when stress, opportunity, and peers converge.

5.4 The role of risk and protective factors

Modern criminology often uses the language of risk factors and protective factors rather than claiming one direct cause. This is helpful because crime is probabilistic rather than inevitable.

Common risk factors

• poor parental supervision,
• child abuse or neglect,
• school failure,
• delinquent peers,
• substance abuse,
• unemployment,
• community violence,
• impulsivity,
• and prior offending.

Common protective factors

• strong attachment to caregivers,
• educational engagement,
• prosocial peers,
• stable employment,
• emotional regulation,
• community support,
• and positive identity.

A person with multiple risk factors is not guaranteed to offend, but the probability increases. A person with strong protective factors may resist risks that would otherwise lead to crime.

5.5 Desistance from crime

Criminology must explain not only why people offend but also why they stop. Desistance refers to the process of ending criminal behaviour. Important desistance factors include:

• employment,
• marriage or stable relationships,
• parenthood,
• identity change,
• maturation,
• reduced association with criminal peers,
• and effective intervention.

Desistance research is valuable because it challenges the assumption that once a person becomes delinquent, they remain that way forever. Many offenders change as their life circumstances and self-concept change.

5.6 Applying theories to South African contexts

For South African students, exam answers are stronger when they link theory to local realities without forcing simplistic explanations. Crime in South Africa is shaped by:

• historical inequality,
• poverty and unemployment,
• spatial segregation,
• violence exposure,
• substance misuse,
• family stress,
• and uneven access to opportunity.

A sociological theory may explain why some communities experience persistent violence. A psychological theory may explain why some youth respond with impulsive aggression after trauma. A biosocial perspective may explain why repeated exposure to stress affects emotional regulation. An integrated theory is therefore often the most realistic way to describe crime in the South African context.

5.7 How to structure an exam answer on etiology

When asked to explain the etiology of crime, a strong answer should follow a clear structure:

1. Define etiology and explain that crime has multiple causes.
2. Identify the main theoretical approaches:
   • biological,
   • psychological,
   • sociological,
   • developmental/integrated.
3. Explain key concepts in each theory.
4. Compare strengths and weaknesses.
5. Apply the theories to an example such as youth violence, gang crime, theft, or white-collar crime.
6. Conclude with a balanced view that crime is multifactorial.

5.8 Comparison table of major theories

Theory	Main focus	Crime explanation	Strength	Limitation
Biological	Genes, brain, hormones, physiology	Crime linked to predispositions and neurodevelopment	Explains temperament and impulsivity	Can become deterministic
Psychodynamic	Unconscious conflict, childhood development	Crime linked to weak internal controls and early trauma	Highlights early experience	Hard to test empirically
Cognitive	Thinking, moral reasoning, decision-making	Crime linked to distorted thinking and poor judgment	Useful for interventions	Underplays structure
Learning	Observation, reinforcement, association	Crime is learned from others	Explains peer and family influence	Does not fully explain initial learning
Self-control	Impulsivity and low self-control	Crime results from weak self-regulation	Simple and broad	Oversimplifies social causes
Strain	Blocked goals and negative emotions	Crime is an adaptation to strain	Explains anger and frustration	Not all strained people offend
Social disorganization	Weak communities and informal control	Crime flourishes where social order is weak	Strong for neighbourhood analysis	Less focused on individuals
Labeling	Social reaction and stigma	Crime can be amplified by labeling	Explains justice system effects	Does not explain initial offending
Conflict	Power and inequality	Crime definitions reflect social power	Highlights structural injustice	Can be too broad
Developmental	Offending over the life course	Crime changes with age and circumstances	Most realistic and flexible	Complex to measure

5.9 Final revision points

Before an exam, remember these high-value points:

• No single theory explains all crime.
• Crime is influenced by individual traits and social structure.
• Childhood matters, but so do peers, schools, communities, and opportunities.
• Etiological theories explain both why people start offending and why they continue or stop.
• Strong answers compare theories rather than listing them separately.
• Use examples to show understanding, not just memorization.
• When in doubt, emphasize interaction, development, and context.

5.10 Model concluding synthesis

The etiology of crime is best understood as a field of competing and complementary explanations. Biological theories show that some individuals may be more vulnerable to impulsivity or aggression. Psychological theories explain how thought patterns, emotions, and learned behaviour shape offending. Sociological theories show that poverty, inequality, communities, peers, and institutions influence crime rates and criminal opportunities. Developmental theories then connect these elements over time, showing how offending begins, changes, and sometimes ends. For exam purposes, the most convincing position is that crime is multicausal, developmental, and context-dependent.

A final high-quality answer should not claim that one theory “wins” completely. Instead, it should demonstrate that criminology has moved from simple single-cause explanations toward more nuanced accounts of how people, environments, and social systems interact to produce criminal behaviour.
