- Posits media influences public's perception of issue importance by emphasizing certain topics and stories over others
- refers to issues and topics receiving the most coverage and prominence in news media (front-page placement, lead stories)
- consists of issues and topics the public considers most important, often mirroring media agenda (through opinion polls, social media trends)
- Occurs in two levels:
- focuses on of issues
- (attribute agenda-setting) focuses on attributes or characteristics of those issues
- Concept of need for orientation suggests individuals with high relevance and low certainty about an issue are more susceptible to agenda-setting effects
- Intermedia agenda-setting refers to influence of different media outlets on each other's news coverage and priorities (newspapers influencing television news)
Theoretical foundations and development
- Originated from Walter Lippmann's concept of "pictures in our heads" and Bernard Cohen's assertion that media may not tell people what to think, but what to think about
- Seminal study by McCombs and Shaw (1968) on 1968 U.S. presidential election found strong correlation between media emphasis on issues and voters' perceived importance of those issues
- Subsequent studies expanded theory to include second-level agenda-setting, need for orientation, and intermedia agenda-setting
- Continues to evolve with changing media landscape, incorporating social media, online news, and fragmented audiences
Media influence on issue salience
Factors shaping media agenda
- Media outlets select and prioritize stories based on newsworthiness, sensationalism, and alignment with organizational goals or biases
- Gatekeeping process involves journalists, editors, and media organizations deciding which stories to cover and how to present them
- News values such as timeliness, proximity, prominence, and conflict guide selection and emphasis of stories
- Organizational factors like ownership, advertising, and target audience also influence media agenda
Effects on public perception and opinion
- Issues receiving frequent, prominent, and sustained media coverage are more likely to be perceived as important by the public
- Framing, or the way media presents an issue, can influence public perception by emphasizing certain aspects or perspectives while downplaying others (episodic vs. thematic framing)
- Agenda-setting effects are stronger for unobtrusive issues, which are issues that individuals have little personal experience with and rely on media for information (foreign policy, environmental issues)
- Cumulative effect of repeated media exposure to an issue over time can lead to long-term changes in public opinion and priorities
- Agenda-setting can prime the public to evaluate political leaders based on their performance on media-emphasized issues
Agenda-setting in political discourse
Strategic use by political actors
- Political candidates and campaigns strategically use agenda-setting to focus public attention on issues that favor their positions or narratives
- Campaigns may attempt to control the media agenda through press releases, staged events, and targeted messaging
- Political advertising can also set the agenda by emphasizing certain issues or attacking opponents on specific topics
- Successful agenda-setting can help candidates define the terms of political debate and rally support around their preferred issues
Impact on political priorities and decision-making
- Media coverage of political scandals, gaffes, or controversies can overshadow substantive policy issues and shift the political agenda (Clinton-Lewinsky scandal)
- Agenda-setting can contribute to polarization of political discourse by amplifying partisan perspectives and limiting exposure to diverse viewpoints
- Rise of social media and alternative news sources has decentralized agenda-setting power, allowing for more grassroots and citizen-driven agenda-setting (Arab Spring, #MeToo movement)
- Agenda-setting research has expanded to examine influence of media on policy agendas and interplay between media, public, and policy agendas (policy agenda-setting)
Limitations of agenda-setting theory
Criticisms and alternative perspectives
- Criticized for oversimplifying complex relationship between media and public opinion, as other factors such as personal experience, interpersonal communication, and individual predispositions also shape issue salience
- Assumes a passive audience that is easily influenced by media, neglecting role of active audience interpretation and resistance to media messages
- Agenda-setting research often relies on correlational data, making it difficult to establish causality between media coverage and public opinion
- Fragmentation of media landscape and rise of selective exposure in the digital age may limit generalizability of traditional agenda-setting findings
Structural and power-related considerations
- Does not adequately address power dynamics and structural factors that shape media agendas, such as ownership concentration, advertising influence, and sourcing routines
- Tends to focus on short-term, issue-level effects rather than long-term, ideological influences of media on public discourse
- Critiqued for not sufficiently considering the role of elite interests and hegemonic power in shaping media and public agendas
- Alternative theories like framing, , and cultivation theory offer complementary or competing explanations for media effects on public opinion and perception
