Peer influence shapes political beliefs by significantly affecting an individual's opinions and attitudes through social interactions. Friends, family, and colleagues may introduce new ideas, reinforce existing beliefs, or challenge perspectives on political issues. This phenomenon can lead to political socialization, where an individual's views align more closely with their peer group's dominant attitudes. Social networks often play a crucial role in propagating ideologies, especially during electoral campaigns where shared information can impact voter turnout and engagement. Ultimately, peer influence can either strengthen political opinions or encourage shifts in belief systems.
