Criminal behavior is a research area that explores the underlying causes and motivations behind individuals engaging in illegal or deviant activities. Researchers in this field examine various factors such as genetic predispositions, environmental influences, and social conditions that may contribute to criminal behavior. They also study the impact of mental health issues, substance abuse, and socio-economic disparities on criminality. The ultimate goal of studying criminal behavior is to develop effective strategies for prevention, intervention, and rehabilitation to reduce crime rates and improve public safety.
