Hirschi's theory that the internalization of norms leads to social control aligns with his Social Control Theory, which is based on the strength of social bonds preventing deviance.
Step-by-step explanation:
Travis Hirschi suggests that the internalization of norms by an individual represents Social Control Theory. This theory explains that social control is directly influenced by the strength of social bonds and that deviance is often the result of a person feeling disconnected from society.
In Hirschi's view, there are four main types of social bonds that attach a person to society: attachment, commitment, involvement, and belief. Attachment refers to our emotional connection to others and the desire for their approval.
Commitment involves our investment in the community such as career and community participation. Involvement means taking part in legitimate social activities that reduce the opportunity for deviance. Lastly, belief signifies the acceptance of common social values which leads to conformity with societal norms.
