Final answer:
The passage is most closely related to the concept of political socialization, which describes how individuals form their political personalities and ideologies. Political socialization is shaped by various influences throughout life and affects one's political behavior and opinions.
Step-by-step explanation:
The passage is most related to the concept of political socialization. Political socialization is defined as the process by which individuals develop their political attitudes, values, and beliefs, typically through influences from family, schools, media, and other societal institutions. It functions as a means through which individuals learn the norms and practices of a political system, shaping their political personality and political culture over time.
As the provided information suggests, one's political ideology is intimately connected with their political socialization. Political ideology is a set of beliefs that guides an individual on how government should operate, and it is based on broader philosophical principles such as individual liberty, social welfare, and economic organization. However, while polling captures the quantified opinions of individuals based on these beliefs, the process of forming these beliefs and opinions pertains to political socialization.
Therefore, understanding the phenomena like the transformation in beliefs after the 9/11 attacks or the divergence in political opinions over time as highlighted by the Pew study, political socialization is a critical concept to examine. It helps us comprehend not just individual political behaviors but also the collective political dynamics within a society.
