Teenage rebellion is a part of social development in adolescents in order for them to develop an identity independent from their parents or family and a capacity for independent decision-making. They may experiment with different roles, behaviors, and ideologies as part of this process of developing an identity. Teenage rebellion has been recognized within psychology as a set of behavioral traits that supersede class, culture, or race; some psychologists, however, have disputed the universality of the phenomenon. According to Terror Management Theory, the child's allegiance to parental authority and worldviews can weaken after the discovery that parents, like themselves and everyone else, are mortal. This realization creates an unconscious need for security that is broader than what the parents alone provide. This can lead to new cultural allegiances, in the search for a more enduring sense of meaning. Teenagers seek to perceive themselves a valued contributor to aspects of culture that more convincingly outlive or transcend the mortal individual's lifespan. However, since the parents also instill their cultural beliefs onto the child, if the child does not come to associate their parents' mortality with their cultural beliefs, the chances of rebellion decrease.
