The agenda-setting theory in political communication posits that media plays a crucial role in determining which topics gain public attention. By choosing which issues to highlight, media influence can shape perceptions of importance among the public and policymakers. This theory emphasizes that while media cannot directly dictate opinions, it can significantly frame discussions and prioritize certain narratives over others. As a result, understanding how media coverage aligns with or diverges from public interests can provide insight into political outcomes and the framing of policies, shaping overall public discourse on critical issues.
