Socialization is a fundamental process in which individuals, especially during their formative years, learn and internalize the norms, values, behaviors, and social expectations of their society. This process plays a crucial role in the development of self-identity, as it helps individuals understand their roles within the larger community and societal structures. Through various means, including family, education, peers, and media, individuals gain insights into societal standards and how to navigate social interactions. This process not only shapes personal identity but also builds a sense of accountability to societal norms, allowing individuals to function effectively within their social environment.
