Political culture shapes public opinion by influencing the values, beliefs, and norms within a society. It determines how people view issues such as government authority, civic duty, and political participation. For instance, a culture that values individualism may foster more critical and questioning attitudes toward authority, while one that prizes collectivism might lead to greater trust in government. Overall, political culture acts as a lens through which individuals interpret political events and issues, subsequently impacting their voting behavior and civic engagement.
