3.2 Agenda-Setting Theory

Agenda-setting theory explores how media shapes public opinion by influencing which issues we think are important. It was first proposed in 1972 by McCombs and Shaw, who found a strong link between media coverage and voter priorities during the 1968 U.S. presidential election.

The theory introduces key concepts like salience transfer, where media attention on an issue increases its perceived importance. It also distinguishes between first-level agenda-setting (issue importance) and second-level agenda-setting (issue attributes), showing how media frames our understanding of topics.

1 of 2

• Maxwell McCombs and Donald Shaw first proposed agenda-setting theory in 1972
• Conducted a study on the 1968 U.S. presidential election to examine the relationship between media coverage and public opinion
• Found a strong correlation between the issues emphasized by the media and the issues voters considered most important
• Concluded that the media has the ability to influence the salience of topics on the public agenda

Salience Transfer in Agenda-Setting

• Salience transfer refers to the media's ability to transfer the importance of an issue from their agenda to the public's agenda
• Media coverage of an issue increases its perceived importance among the public
• The more attention the media gives to an issue, the more likely the public is to consider it important
• Salience transfer occurs through repeated coverage and prominence of issues in the media (front page placement, lead stories)

Key Concepts in Agenda-Setting

Public Agenda and Media Agenda

• Public agenda consists of the issues the general public considers important at a given time
• Determined by surveys asking people to identify the most important issues facing the country
• Media agenda refers to the issues and topics that receive the most coverage and prominence in the media
• Determined by analyzing the amount and placement of news stories on various issues

First-Level and Second-Level Agenda-Setting

• First-level agenda-setting focuses on the transfer of issue salience from the media to the public
• Examines the relationship between the amount of media coverage an issue receives and its perceived importance among the public
• Second-level agenda-setting, also known as attribute agenda-setting, goes beyond issue salience
• Focuses on how the media's portrayal of issue attributes (characteristics, qualities, or sub-issues) influences public perceptions
• Examines how the media's framing of an issue can shape public understanding and opinions about that issue

Related Effects and Audience Factors

Priming and Its Relationship to Agenda-Setting

• Priming is a related media effect that builds upon agenda-setting theory
• Occurs when the media's emphasis on certain issues influences the criteria by which the public evaluates political leaders, policies, or events
• Media coverage can "prime" the public to give greater weight to specific issues when making judgments
• For example, if the media frequently covers economic issues, the public may be primed to evaluate political candidates primarily based on their economic policies

Need for Orientation and Its Impact on Agenda-Setting Effects

• Need for orientation refers to an individual's desire to understand and make sense of their environment
• Consists of two dimensions: relevance and uncertainty
  • Relevance refers to the perceived importance of an issue to an individual
  • Uncertainty refers to the lack of knowledge or understanding about an issue
• Individuals with a high need for orientation are more susceptible to agenda-setting effects
• They actively seek information from the media to reduce uncertainty and make sense of relevant issues
• Conversely, individuals with a low need for orientation are less influenced by the media's agenda, as they may have pre-existing knowledge or low interest in the issues covered
