ABSTRACT In Hearing the Other Side, Diana Mutz poses a conundrum: The more one is exposed to political disagreement, the more likely one is to withdraw from political engagement. This behavior may result in part from the political polarization of recent decades, but it may also be due to the traditional media, which tend to magnify political competition and portray it as a bitter conflict. The rise of the Internet and social media offered hope that people might more readily encounter (...) the arguments of the other side. Recent research suggests, however, that people thus far tend to consume political information online just as they do offline: selectively. (shrink)

Robert Jervis's System Effects (1997) shares a great deal with game theory, complex-systems theory, and systems theory in international relations, yet it transcends them all by taking account of the role of ideas in human behavior. The ideational element inserts unpredictability into Jervis's understanding of system effects. Each member of a ?system? of interrelated actors interprets her situation to require certain actions based on the effects these will cause among other members of the system, but these other actors' responses to (...) one's action will be based on their own perceptions of their situation and their interpretations of what it requires. These ideas are fallible, but we cannot predict the mistakes people will make if the errors are based on information we do not have or do not interpret in the same way they do. Not only members of a system but social-scientific observers and policy makers are ignorant of others' information and interpretations, and therefore are as likely to err in their behavioral predictions as are members of the system. Thus, Jervis's book raises serious questions about how to evaluate policies directed toward producing positive system effects. The questions are unanswerable at this point, but they might be susceptible to analysis by an ambitious form of political theory. (shrink)

Zaller's Nature and Origins of Mass Opinion initially sets out an epistemic view of politics in which the ultimate determinants of political action are ideas about the society in which we act. These ideas are usually mediated to us by others, so Zaller begins the book by describing its topic as the influence of the media on public opinion, and he includes journalists among the “political elites” who exert this influence (along with politicians, public officials, and experts). But the book (...) eventually reduces journalists to being messengers of politicians' cues to the public. This understanding of the media is built into the book's model of opinion formation, in which cued predispositions are pivotal to the acceptance or rejection of culturally mediated “messages”—but are themselves insulated from cultural influence. A cueing model of message reception, however, ignores messages that are differentially persuasive not because of the predispositions they cue but the content they convey. Gauging the heterogeneous persuasiveness of messages requires qualitative content analysis and cultural contextualization, and if this research is to contribute to a general understanding of public opinion, it will have to extend beyond news-media messages to ideational influences carried in high culture, formal education, and the entertainment media. All of these sources of ideas, in turn, may contribute to the shaping of predispositions, as suggested in part by public opinion regarding the Vietnam War. Research of this kind would signal a new type of political science that focused on the actual thoughts of real people trying to understand a complex environment: exactly the type of political science suggested at the beginning of Zaller's book.
