Final answer:
The Media is not characteristic of 'primary groups' of political socialization, as primary groups like Family, Peers, and Educational institutions provide direct, personal, and ongoing influence, whereas the Media is considered a secondary agent.
Step-by-step explanation:
Among the options provided, Media is not characteristic of 'primary groups' of political socialization. Primary groups in political socialization typically refer to groups that have a direct, personal, and pervasive impact on an individual, shaping their political attitudes and beliefs from an early age. These include the Family, which is often seen as the foremost influence on early political socialization, and Peers, who become particularly influential during adolescence when individuals start to develop an identity separate from their parents. Educational institutions are another primary group that influence political socialization by formally teaching individuals about political systems and social norms. The Media, however, while being a significant source of political information and influence, does not typically offer the same level of intimate, personalized interactions as the other groups mentioned and is therefore not considered a primary group. It is more accurately described as a secondary agent of political socialization.
