Kevin Arceneaux - Böcker

We live in an age of media saturation, where with a few clicks of the remote - or mouse - we can tune in to programming where the facts fit our ideological predispositions. But what are the political consequences of this vast landscape of media choice? Partisan news has been roundly castigated for reinforcing prior beliefs and contributing to the highly polarized political environment we have today, but there is little evidence to support this claim, and much of what we know about the impact of news media come from studies that were conducted at a time when viewers chose from among six channels rather than scores. Through a series of innovative experiments, Kevin Arceneaux and Martin Johnson show that such criticism is unfounded. Americans who watch cable news are already polarized, and their exposure to partisan programming of their choice does not significantly change their initial position. In fact, the opposite is true: viewers become more polarized when forced to watch programming that opposes their beliefs.A much more troubling consequence of the ever-expanding media environment, the authors show, is that it has allowed people to tune out the news: the four top-rated partisan news programs draw a mere three percent of the total number of people watching television. Overturning much of the conventional wisdom, Changing Minds or Changing Channels? demonstrates that the strong effects of media exposure found in past research are simply not applicable in today's more saturated media landscape.

The influence of partisan news is presumed to be powerful, but evidence for its effects on political elites is limited, often based more on anecdotes than science. Using a rigorous quasi-experimental research design, observational data, and open science practices, this book carefully demonstrates how the re-emergence and rise of partisan cable news in the US affected the behavior of political elites during the rise and proliferation of Fox News across media markets between 1996 and 2010. Despite widespread concerns over the ills of partisan news, evidence provides a nuanced, albeit cautionary tale. On one hand, findings suggest that the rise of Fox indeed changed elite political behavior in recent decades. At the same time, the limited conditions under which Fox News' influence occurred suggests that concerns about the network's power may be overstated.

The success of democratic governance hinges on an electorate's ability to reward elected officials who act faithfully and punish those who do not. Yet there is considerable variation among voters in their ability to objectively evaluate representatives' performance. In this book the authors develop a theoretical model, the Intuitionist Model of Political Reasoning, which posits that this variation across voters is the result of individual differences in the predisposition to reflect on and to override partisan impulses. Individuals differ in partisan intuitions resulting from the strength of their attachments to parties, as well as the degree to which they are willing to engage in the cognitively taxing process of evaluating those intuitions. The balance of these forces - the strength of intuitions and the willingness to second guess one's self - determines the extent to which individuals update their assessments of political parties and elected officials in a rational manner.
