After introducing agenda setting and priming, I want to complete the "holy trinity of media effects" with a short introduction of framing, which I consider to be the most important effect of this threesome. Whereas agenda setting tells us what to think about (by putting issues on the public agenda), framing tells us how and why to think about an issue. To frame means to communicate in a way that leads audiences to see something in a certain light or from a particular perspective. Aspects that are not included in the frame do not come to the audience's attention. Framing determines where the audience puts its attention. Effective framing taps into preexisting beliefs, attitudes, and opinions; it highlights certain aspects of an issue over other aspects.
In my last blog post, I introduced agenda setting as a fundamental media effect: The media sets the public and the political agenda by bringing issues to the attention of the audience and of policy makers. Agenda setting has a little brother, priming, sometimes called second order agenda setting. Priming effects of communication are important for decision making, for example which candidate to vote for in an upcoming election.
