Final answer:
The book 'The Rational Public: Fifty Years of Trends in Americans' Policy' by Benjamin I. Page and Robert Y. Shapiro supports the view of the public as wise and reasonable. It highlights the role of informed public opinion in democratic governance and emphasizes the media's duty to present diverse viewpoints for a healthy democracy.
Step-by-step explanation:
The publication that suggests the public is wise and reasonable in its opinions is 'The Rational Public: Fifty Years of Trends in Americans' Policy' by Benjamin I. Page and Robert Y. Shapiro. This work analyzes data over several decades to explore the nature of the public's policy preferences, indicating a rational public when viewed collectively over time. This notion aligns with the theories of the public sphere as formulated by Jürgen Habermas, identifying newspapers as critical in nurturing an informed public engaging in rational-critical debate that influences democratic governance.
The presence of the rational public is crucial in a democracy as it contributes to the balance of power between the public's opinion and the political arena, especially considering the media's role as a gatekeeper. A well-informed public can hold governing bodies accountable, ensuring that government policy reflects the collective will. This balance is further discussed in the works of scholars like Carroll J. Glynn and others in their book 'Public Opinion', underscoring the importance of multiple viewpoints and media plurality for a healthy discourse and democracy.
However, the question also brings to light an enduring concern about the limitations of public knowledge, as tackled by the Pew Research Center and other sources. These publications raise the issue of whether the public's understanding of current affairs is sufficiently informed to yield a rational opinion, which is vital for the effective functioning of democratic systems. Hence, the media's role in providing diverse coverage and the public's engagement with it are seen as essential for fostering a rationale and involved citizenry.
