Final answer:
The absence of a particular viewpoint in editorials and TV talk shows suggests media bias, where certain opinions are underrepresented or ignored. This affects the perceived balance of power between the public and political agents in shaping the media narrative and influencing public policy.
Step-by-step explanation:
When a particular viewpoint is not noted in editorials or reflected in the selection of guests on a television talk show, it indicates a form of media bias. This bias can manifest as an imbalance, where certain viewpoints are marginalized, creating a skewed perception of the full spectrum of opinions on an issue. Bias by the selection of sources occurs when editorials or talk shows include more sources that support one view over another or when they fail to provide a platform for diverse perspectives, thus influencing public opinion and policy discussions. In particular, viewpoints expressed by officials, such as members of Congress, are generally more prominent, echoing V. O. Key's statement that "The voice of the people is but an echo." Notably, the opinions of political elites and opinion leaders are often highlighted; they hold influence by guiding how the public should react to political debates. This dynamic questions the existence of a true balance of power between those in the political arena and the public, with regard to the media's role as a gatekeeper.
