Theories of Criminal Behavior

Why Do People Commit Crimes?

Criminologists have developed many theories to explain why individuals break the law. These theories help us understand behavior and design better prevention strategies.

Major Criminological Theories

  • Biological theories: Suggest some people are born with traits that make them more likely to commit crimes.
  • Psychological theories: Focus on mental health, personality, and early experiences.
  • Sociological theories: Look at society, family, peer groups, and economic conditions.

Real-World Use

Policymakers and police use these theories to help reduce crime by addressing its root causes.

Multiple Factors

Most criminologists agree crime is caused by a mix of biological, psychological, and social factors—not just one.

Examples

  • A youth joins a gang because of peer pressure in a high-crime neighborhood.

  • A person with a mental illness may be more vulnerable to breaking the law.
