Biological Theories of Deviance

Definition

Biological theories of deviance are explanations that focus on how biological factors, such as genetics, brain structure, and hormones, influence an individual's likelihood of engaging in behaviors considered deviant by society. These theories suggest that certain physical traits or biological processes can predispose people to behave in ways that differ from societal norms.

Example

A person may frequently exhibit aggressive behavior, such as getting into fights or breaking rules at school. Researchers might explore whether this behavior is linked to factors like low levels of serotonin (a brain chemical associated with mood regulation) or differences in the structure of the person's brain compared to peers. If studies show that the individual has a genetic predisposition for impulsivity and aggression, biological theories would suggest that these traits contribute to their deviant behavior.

Why it Matters

Understanding biological theories of deviance is important because they help explain why some people might be more prone to engaging in behaviors considered deviant. This knowledge can lead to better interventions, such as medications or therapies tailored to address underlying biological factors.
