Travis Hirschi finds socialization into society's conventional believe system as a fundamental factor in preventing deviance.
Thus, socialization, bonding and social control are the most important factors for him. Â
Within other factors we also have, commitment to social norms, seeking social rewards, and the quest for conventionality as external factors with less magnitude.
I believe that self control is fundamental but this one can only be built or be part of someone's personality as a consequence of an individual's social surroundings.
Thereby, I think social surrounding is the most important factor when forging personality.
