Agenda setting may work through information retention or through viewer rumination.

Evidence

Here we explore two. According to the first, more news coverage of a problem leads to the acquisition and retention of more information about the problem, which in turn leads to the judgment of the problem as more important. According to the second, news coverage of a problem provokes the viewer to consider the claims being advanced; depending on the character of these ruminations, agenda setting will be more or less powerful. — John T. Jost and Jim Sidanius, Political Psychology, 1449
