Biological theory of deviance proposes that certain biological factors, such as genetics or brain structure, play a role in influencing deviant behavior. Some researchers argue that abnormalities in these biological factors can predispose individuals to engage in antisocial or criminal behavior, although environmental factors also interact with biological factors to shape behavior. However, it is important to consider the ethical implications and limitations of solely attributing deviance to biological factors, as social and environmental factors also influence an individual's propensity for deviant behavior.
