Cesare Lombroso was an Italian criminologist who pioneered the theory of the “born criminal,” arguing that criminality is an inherited trait reflected in physical characteristics.
Cesare Lombroso and His Contributions to Criminology
Cesare Lombroso (1835–1909) is often considered the father of modern criminology. His work laid the foundation for biological theories of crime, marking a shift from classical criminology, which emphasized free will and rational choice. Instead, Lombroso believed that criminals were biologically different from law-abiding citizens and that their deviant behavior could be identified through physical traits. While his theories have been largely discredited, they played a crucial role in the development of criminology as a scientific discipline.
Early Life and Background
Cesare Lombroso was born in Verona, Italy, in 1835. He studied medicine at the University of Pavia and later specialized in psychiatry and anthropology. His medical background influenced his approach to criminology, leading him to apply scientific methods to the study of criminal behavior.
While working as a physician in Italian prisons, Lombroso observed physical differences among inmates. He believed these differences indicated a biological predisposition to crime. His observations formed the basis of his most famous theory: the atavistic criminal.
The Theory of the “Born Criminal”
Lombroso introduced the idea that criminals were biological throwbacks to an earlier stage of human evolution. He argued that some individuals were “born criminals” and could be identified by specific physical traits, such as:
- Asymmetrical facial features
- Large jaws and cheekbones
- Long arms
- Excessive wrinkles
- High cheekbones
- Large ears or noses
- Abnormal dentition (irregular teeth)
According to Lombroso, these traits were signs of atavism, meaning that criminals were evolutionary regressions—more primitive humans who lacked the ability to conform to modern society’s norms. This perspective aligned with the early scientific racism of the 19th century, which wrongly suggested that certain groups were biologically inferior.
Lombroso’s Criminal Classifications
Cesare Lombroso believed that criminals were not a uniform group but could be classified into different categories based on their underlying motivations and characteristics. His classification system aimed to distinguish between individuals who were inherently criminal and those whose criminal behavior resulted from environmental or psychological factors. While his categories were based on his now-debunked biological theories, they influenced early attempts to categorize offenders in criminology.
Born Criminals
Lombroso’s most controversial category was the born criminal, a term he used to describe individuals whom he believed were biologically predisposed to crime. He argued that these individuals were atavistic throwbacks, meaning they had not evolved to the same level as non-criminal members of society. According to Lombroso, born criminals had physical abnormalities that linked them to earlier stages of human evolution, such as large jaws, asymmetrical facial features, long arms, and excessive wrinkles. He believed that these traits indicated a natural inclination toward deviant behavior and that such individuals were beyond rehabilitation.
Born criminals were seen as the most dangerous offenders because their criminal tendencies were thought to be instinctive rather than learned. Lombroso suggested that society needed strict measures, including lifelong imprisonment or even capital punishment, to control these individuals. His theory of born criminals was later criticized for its lack of scientific validity and its reinforcement of racial and social biases.
Criminaloids
Unlike born criminals, criminaloids were individuals who committed crimes due to environmental influences rather than biological traits. Lombroso believed that these individuals had no innate criminal predisposition but were vulnerable to external pressures, such as poverty, peer influence, or social conditions. He argued that criminaloids were more common than born criminals and that their behavior could often be explained by circumstances rather than inherited traits.
Criminaloids included a wide range of offenders, from petty thieves to individuals who committed crimes under emotional distress. Lombroso suggested that while these individuals were not necessarily destined for criminality, they could become habitual offenders if exposed to the wrong influences. This category foreshadowed later sociological criminology, which examines how environmental factors contribute to crime.
Occasional Criminals
The occasional criminal was someone who broke the law under specific circumstances but was not considered inherently criminal or likely to reoffend. Lombroso recognized that many individuals commit crimes due to situational pressures rather than long-term criminal tendencies. He divided occasional criminals into three subcategories:
- Pseudo-criminals – Those who committed crimes unintentionally or in self-defense. These individuals did not have criminal intent and, in many cases, were not considered morally or legally responsible for their actions.
- Criminals by Passion – Those who committed crimes due to strong emotions, such as jealousy or anger, rather than a habitual tendency to break the law. These offenders were often seen as acting out of impulse rather than calculation.
- Habitual Offenders – Individuals who had initially committed minor offenses but gradually became more involved in crime due to repeated exposure to criminal behavior or life circumstances that pushed them toward deviance.
Lombroso’s concept of occasional criminals acknowledged that not all offenders are the same, and some individuals might never commit another crime after their initial offense. This idea aligns with modern criminology’s recognition that many factors, including life experiences and social environments, influence criminal behavior.
Insane Criminals
Lombroso also classified a group of offenders as insane criminals, who committed crimes due to mental illness or psychological disorders. Unlike born criminals, these individuals were not seen as biologically predetermined to commit crimes but rather as individuals suffering from conditions that impaired their judgment or impulse control. Lombroso included individuals with schizophrenia, epilepsy, and other psychiatric disorders in this category.
He argued that insane criminals required different treatment from other offenders, as their crimes were often linked to their mental health conditions rather than an inherent tendency toward criminality. This category contributed to early discussions about the relationship between mental illness and criminal behavior, influencing later developments in forensic psychology and criminal psychiatry.
Lombroso’s Legacy in Criminal Classification
Lombroso’s classification system was an early attempt to differentiate between different types of criminals, even though his underlying theories about biological determinism were incorrect. While modern criminology rejects the idea that physical traits determine criminal behavior, Lombroso’s recognition that criminals are not a single, homogeneous group remains relevant. Today, criminologists and forensic psychologists continue to classify offenders based on psychological, social, and environmental factors rather than purely biological ones.
His work paved the way for more sophisticated theories on criminal typologies, including the study of career criminals, situational offenders, and the impact of psychological disorders on crime. Though flawed, Lombroso’s ideas contributed to the ongoing effort to understand and categorize criminal behavior in a way that informs both law enforcement and rehabilitation efforts.
The Shift from Classical to Positivist Criminology
Before Cesare Lombroso’s work, criminology was dominated by classical criminology, a school of thought developed by thinkers like Cesare Beccaria and Jeremy Bentham in the 18th century. Classical theorists viewed crime as a rational choice, arguing that individuals committed crimes after weighing the potential benefits and consequences. This perspective assumed that all people had free will and that crime could be controlled through appropriate punishments. The goal of classical criminology was to create fair and proportional laws that deterred crime by making punishment outweigh the benefits of criminal behavior.
Lombroso’s work challenged these classical ideas by introducing positivist criminology, which emphasized that criminal behavior was influenced by factors beyond an individual’s control. Rather than seeing crime as a rational decision, positivists sought to study it scientifically, using methods like observation, measurement, and data collection. Lombroso’s theories suggested that criminals were biologically different from non-criminals, shifting the focus from legal principles to the scientific study of crime and criminal behavior. This marked a turning point in criminology, as scholars began looking at crime as a phenomenon influenced by biology, psychology, and environmental conditions rather than solely by free will.
It is important to note that positivism is not a single theory, but rather a broader approach to studying crime. Unlike classical criminology, which was built on a specific set of philosophical principles, positivist criminology encompasses multiple theories that seek to explain crime through empirical research. Lombroso’s biological determinism was one of the earliest positivist theories, but later criminologists expanded the approach by incorporating psychological and sociological factors. The work of scholars like Émile Durkheim, Sigmund Freud, and Robert Merton demonstrated that crime could be influenced by social structures, mental health, and economic conditions.
While Lombroso’s biological explanations have been discredited, the positivist approach remains a fundamental part of criminology today. Modern criminologists continue to use scientific methods to study crime, including genetics, neuroscience, and psychological profiling. The shift from classical to positivist criminology laid the groundwork for evidence-based policies and a deeper understanding of the complex causes of criminal behavior.
Criticism and the Decline of Lombroso’s Theories
While Cesare Lombroso’s theories were groundbreaking in their time, they soon faced extensive criticism as scientific knowledge and research methods improved. His ideas, particularly the concept of the “born criminal,” were challenged on multiple fronts, leading to their eventual decline in credibility. Critics argued that his research was methodologically flawed, relied on biased assumptions, and failed to account for the complex social and environmental factors influencing criminal behavior. As criminology evolved, scholars moved away from his biological determinism and toward more comprehensive explanations of crime.
One of the primary criticisms of Lombroso’s work was its lack of scientific rigor. His studies were based on observations of prison populations, but he failed to compare his findings with non-criminal groups. Without proper control groups, his conclusions lacked validity. Furthermore, his reliance on anecdotal evidence rather than systematic experimentation weakened the credibility of his claims. Modern criminologists emphasize the importance of peer-reviewed research, statistical analysis, and replication of findings—standards that Lombroso’s work did not meet.
Another major issue was his flawed assumptions about physical traits and criminality. Many of the characteristics Lombroso associated with criminals—such as large jaws, asymmetrical faces, and long arms—were later found to be common among the general population. There was no scientific basis for linking these physical features to criminal behavior. As forensic science advanced, researchers found that factors such as psychological traits, upbringing, and socioeconomic conditions played a far greater role in shaping criminal tendencies.
Lombroso’s theories also reflected racial and social biases. His work contributed to the pseudoscience of the time, which sought to link criminality to specific racial or ethnic groups. His ideas were misused to justify discrimination against marginalized communities, reinforcing harmful stereotypes that associated certain physical appearances with criminal behavior. This bias made his theories not only scientifically unsound but also ethically problematic.
Additionally, Lombroso’s overemphasis on biology ignored the significant role of social, economic, and environmental factors in crime. Later criminological research demonstrated that poverty, education, family structure, peer influence, and mental health have a much greater impact on criminal behavior than inherited traits. The emergence of sociological criminology, led by thinkers such as Émile Durkheim and Robert Merton, further debunked the idea that criminality was purely biological.
As fields like psychology, sociology, and genetics advanced, Lombroso’s deterministic views on crime lost credibility. However, his work still influenced later studies in criminal profiling and forensic psychology. Modern biological criminology has moved beyond Lombroso’s focus on physical appearance and now examines genetics, neurobiology, and brain function to better understand criminal behavior. While Lombroso’s theories are no longer accepted, his legacy remains in the continued effort to apply scientific methods to the study of crime.
Lombroso’s Influence on Modern Criminology
Despite the flaws in his theories, Cesare Lombroso played a crucial role in shaping modern criminology. His emphasis on studying criminals through scientific observation and empirical research marked a turning point in the field. Before Lombroso, criminology was largely based on legal philosophy, focusing on crime as a moral failing or a rational choice. His approach shifted the focus toward understanding crime as a phenomenon influenced by biological, psychological, and environmental factors. Although his conclusions have been discredited, his contributions laid the groundwork for more rigorous scientific studies of criminal behavior.
One of Lombroso’s most significant impacts was the birth of positivist criminology. Unlike the classical school, which emphasized free will and rational decision-making, Lombroso’s work introduced the idea that criminal behavior could be studied scientifically. His reliance on observation and data collection encouraged criminologists to look beyond legal principles and consider measurable factors that might contribute to criminality. This shift moved criminology closer to the social sciences, inspiring later research that incorporated psychology, sociology, and biology.
Lombroso also played a key role in criminal anthropology, a subfield that examines the relationship between human biology and criminal behavior. While his theory of atavism has been debunked, his early efforts to classify criminals and study their characteristics contributed to later advancements in forensic science and psychological profiling. His work encouraged researchers to explore how genetics, brain function, and environmental influences shape criminal tendencies.
Another lasting impact of Lombroso’s work was his use of empirical research in criminology. By applying scientific methods, he encouraged future criminologists to rely on data, case studies, and experiments rather than abstract theories. His influence can be seen in contemporary criminology, where researchers use statistical analysis, psychological assessments, and neuroscience to understand crime and develop effective prevention strategies.
Conclusion
Cesare Lombroso’s theories may be outdated, but his influence on criminology remains significant. He shifted the field toward scientific inquiry and helped lay the foundation for modern criminological research. While his ideas about biological determinism have been debunked, they served as a starting point for later theories that consider the complex interplay of biological, psychological, and social factors in criminal behavior.
