Born Criminal Theory by Cesare Lombroso: Definition, Impact, and Criticism

the born criminal

The history of criminology is filled with debates over whether crime is a product of nature, nurture, or a combination of both. In the late 19th century, one of the most influential and controversial figures in criminology, Cesare Lombroso, introduced the concept of the “Born Criminal.” His theory suggested that some individuals are biologically predisposed to commit crimes and that their deviant behavior could be identified through physical characteristics.

This idea, rooted in what Lombroso called atavism, was revolutionary at the time. It represented the beginning of the positivist school of criminology, which sought to explain crime through scientific observation rather than moral or religious frameworks. Lombroso’s theory became the foundation for criminal anthropology, an emerging discipline that studied the physical and psychological traits of offenders.

While Lombroso’s theory of the born criminal was groundbreaking in its attempt to apply science to the study of crime, it has also been heavily criticized for its deterministic approach and its reliance on physical stereotypes. Nevertheless, his work remains an essential chapter in criminological thought, influencing generations of scholars, policymakers, and even contemporary debates on genetics and crime.

In this article, we will explore the origins of the born criminal theory, its core principles, Lombroso’s research methods, his classification of criminals, the criticism it received, and its lasting impact on modern criminology.


Cesare Lombroso: The Father of Criminal Anthropology

To understand the born criminal theory, it is important to examine the life and intellectual background of Cesare Lombroso (1835–1909). Born in Verona, Italy, Lombroso trained as a physician and psychiatrist before turning his attention to criminology. He lived during a period when scientific thought was rapidly advancing, influenced by Darwin’s theory of evolution, advances in medicine, and the rise of positivism in the social sciences.

Lombroso’s medical training exposed him to the study of abnormal psychology and physical pathology, which he later applied to criminals. As a military doctor, he examined soldiers, the mentally ill, and prisoners. These experiences shaped his conviction that criminal behavior could be linked to biological factors.

His most significant contribution came with the publication of “L’Uomo Delinquente” (The Criminal Man) in 1876, a book that revolutionized criminology by proposing that criminality could be scientifically studied through the observation of physical traits. Lombroso argued that crime was not simply a moral failing but could be explained by biological determinism—the idea that some people are inherently predisposed to deviant behavior.

By introducing this concept, Lombroso founded the Italian Positivist School of Criminology. This school rejected the classical criminology notion that crime was solely a matter of free will and rational choice. Instead, Lombroso and his followers emphasized determinism, proposing that criminality was shaped by forces beyond individual control, particularly biology.

The Born Criminal: Core Idea of Lombroso’s Theory

At the heart of Lombroso’s criminology lies the Born Criminal Theory. According to him, certain individuals are predisposed to crime because they are evolutionary throwbacks, or atavists, who represent a regression to earlier stages of human development.

Lombroso believed that these individuals carried primitive traits that set them apart from modern, civilized humans. In his view, born criminals were closer to “savages” or “primitive men” than to law-abiding citizens. Their deviant behavior was thus not a product of rational decision-making but of biological destiny.

Some of the physical traits Lombroso associated with born criminals included:

  • Asymmetrical faces and skulls
  • Large jaws and protruding chins
  • Long arms relative to body size
  • Large ears
  • High cheekbones
  • Flattened or receding foreheads
  • Excessive tattoos (which he linked to primitive expression)

Lombroso claimed that these traits could be used to identify criminals before they even committed crimes. This approach implied that criminality could be detected through anthropometric measurements—an idea that fascinated both scientists and policymakers at the time.

The radical aspect of Lombroso’s theory was its determinism: the belief that born criminals had little choice in their behavior because it was rooted in their biology. In this sense, the born criminal was seen as fundamentally different from the rest of society.


Lombroso’s Methods and Research

Lombroso’s theory was grounded in what he considered empirical research. His methods, though controversial today, were pioneering at the time.

His most famous discovery came during an autopsy of an infamous criminal named Giuseppe Villella. Lombroso observed irregularities in Villella’s skull and concluded that these abnormalities indicated a throwback to a primitive human type. This finding became the foundation for his theory of atavism.

Lombroso conducted extensive studies of prisoners, collecting thousands of skulls, skeletons, and photographs. He meticulously measured cranial features, facial angles, and other anatomical details. His goal was to identify patterns that distinguished criminals from non-criminals.

Beyond anatomy, Lombroso also examined tattoos, which he saw as signs of primitiveness and criminality. He argued that criminals were more likely to tattoo their bodies with crude, violent, or sexual images, which reflected their deviant psychology.

Although his methods were flawed by modern standards—lacking proper control groups and relying heavily on anecdotal evidence—they marked an early attempt to apply scientific tools to the study of crime. His reliance on observation, measurement, and classification influenced future developments in criminology and forensic science.


Categories of Criminals According to Lombroso

Lombroso’s work went beyond identifying born criminals. He developed a typology of criminals, categorizing offenders based on their behavior and underlying causes. His classification included:

  1. The Born Criminal
    • Individuals who, due to biological atavism, were destined to commit crimes.
    • Displayed physical stigmata and primitive instincts.
  2. The Insane Criminal
    • Offenders who committed crimes due to mental illness, psychological abnormalities, or degenerative conditions.
  3. The Occasional Criminal
    • Individuals who committed crimes due to circumstances rather than inherent traits.
    • This category recognized the role of environment and opportunity.
  4. The Criminal by Passion
    • People who committed crimes under the influence of strong emotions such as jealousy, love, or honor.
    • Often viewed by Lombroso as morally superior to other types of criminals.

This typology demonstrated Lombroso’s attempt to create a scientific classification system for criminals, similar to how biologists classified species. While the born criminal was his central figure, he acknowledged that not all criminals fit into this category, leaving room for environmental and psychological explanations.

Criticism of the Born Criminal Theory

Despite its influence, Lombroso’s theory was subject to significant criticism, both during his lifetime and in the decades that followed.

  1. Methodological Weaknesses
    • Lombroso’s reliance on physical traits lacked scientific rigor.
    • His sample sizes were biased, as he studied mostly prisoners and institutionalized individuals.
    • He failed to adequately compare criminals with non-criminals in systematic ways.
  2. Determinism and Free Will
    • The theory implied that criminals had no free will, undermining the concept of personal responsibility.
    • Critics argued that this perspective could justify unfair treatment or stigmatization of individuals based on appearance.
  3. Racial and Social Bias
    • Many of Lombroso’s descriptions reflected stereotypes of marginalized groups, fueling discriminatory practices.
    • His emphasis on physical features often mirrored existing prejudices rather than objective science.
  4. Rise of Sociological Theories
    • Later criminologists emphasized the role of poverty, inequality, and social environment in shaping criminal behavior.
    • These factors undermined Lombroso’s claim that biology alone determined criminality.

Although discredited as a scientific explanation of crime, Lombroso’s theory still sparked valuable debates about the causes of criminal behavior and the responsibilities of society in addressing them.


Legacy of Lombroso in Criminology

Even though Lombroso’s theory has been largely rejected, his impact on criminology remains profound.

  • He transformed the study of crime into a scientific discipline, moving away from moralistic or theological explanations.
  • His focus on empirical observation influenced the development of forensic science, psychiatry, and penology.
  • The idea that criminals could be classified and studied scientifically opened the door for later research in psychology and sociology.
  • Lombroso’s legacy also includes the introduction of criminological typologies, which inspired further attempts to categorize criminal behavior.

While his biological determinism is outdated, the positivist tradition he founded continues to influence criminological research today, particularly in the fields of biosocial criminology and neurocriminology.


Modern Views on the Born Criminal Idea

Today, the concept of the “born criminal” is considered scientifically inaccurate, yet elements of Lombroso’s work resonate in modern research. Advances in genetics, neuroscience, and psychology have shown that biological factors can influence behavior, though they interact with social and environmental conditions.

  1. Genetics and Crime
    • Twin and adoption studies suggest a hereditary component to some antisocial behaviors.
    • Genes related to impulsivity and aggression have been linked to criminal tendencies, but they do not determine behavior on their own.
  2. Neurocriminology
    • Brain imaging studies reveal structural and functional differences in the brains of some violent offenders.
    • Conditions such as brain injury or abnormalities in the frontal lobe are associated with poor impulse control.
  3. Interactionist Approaches
    • Modern criminology emphasizes the interaction between biology and environment.
    • Factors such as poverty, trauma, education, and peer influence play crucial roles in shaping behavior.

In this way, contemporary research acknowledges the role of biology without embracing Lombroso’s rigid determinism. Instead of labeling individuals as “born criminals,” modern criminology seeks to understand how biological predispositions interact with social contexts.


Conclusion

Cesare Lombroso’s born criminal theory was one of the most influential and controversial ideas in the history of criminology. By arguing that some individuals were biologically predisposed to crime, Lombroso challenged traditional views of free will and moral responsibility. His work established criminology as a scientific discipline and inspired new ways of thinking about the causes of crime.

However, his reliance on physical traits, flawed methodology, and deterministic worldview ultimately undermined his theory. Modern criminology recognizes the complexity of human behavior, emphasizing the interplay of biological, psychological, and social factors.

Despite its shortcomings, the born criminal theory continues to occupy an important place in criminological thought. It represents both the promise and the pitfalls of applying science to human behavior. By studying Lombroso’s ideas, we gain insight into the evolution of criminology and the ongoing quest to understand the roots of criminality.
