Why voters turn out on Election Day has eluded a straightforward explanation. Rational choice theorists have proposed a parsimonious model, but its logical implication is that hardly anyone would vote since their one vote is unlikely to determine the election outcome. Attempts to save the rational choice model incorporate factors like the expressive benefits of voting, yet these modifications seem to be at odds with core assumptions of rational choice theory. Still, some people do weigh the expected costs and benefits of voting and take account of the closeness of the election when deciding whether or not to vote. Many more, though, vote out of a sense of civic duty. In contrast to the calculus of voting model, the civic voluntarism model focuses on the role of resources, political engagement, and to a lesser extent, recruitment in encouraging people to vote. It pays particular attention to the sources of these factors and traces complex paths among them.
There are many other theories of why people vote in elections. Intergenerational transmission and education play central roles in the civic voluntarism models. Studies that link official voting records with census data provide persuasive evidence of the influence of parental turnout. Education is one of the best individual-level predictors of voter turnout, but critics charge that it is simply a proxy for pre-adult experiences within the home. Studies using equally sophisticated designs that mimic the logic of controlled experiments have reached contradictory conclusions about the association between education and turnout. Some of the most innovative work on voter turnout is exploring the role of genetic influences and personality traits, both of which have an element of heritability. This work is in its infancy, but it is likely that many genes shape the predisposition to vote and that they interact in complex ways with environmental influences. Few clear patterns have emerged in the association between personality and turnout. Finally, scholars are beginning to recognize the importance of exploring the connection between health and turnout.

The news media have been disrupted. Broadcasting has given way to narrowcasting, editorial control to control by “friends” and personalization algorithms, and a few reputable producers to millions with shallower reputations. Today, not only is there a much broader variety of news, but there is also more of it. The news is also always on. And it is available almost everywhere. The search costs have come crashing down, so much so that much of the world’s information is at our fingertips. Google anything and the chances are that there will be multiple pages of relevant results.
Such a dramatic expansion of choice and access is generally considered a Pareto improvement. But the worry is that we have fashioned defeat from the bounty by choosing badly. The expansion in choice is blamed for both, increasing the “knowledge gap,” the gap between how much the politically interested and politically disinterested know about politics, and increasing partisan polarization. We reconsider the evidence for the claims. The claim about media’s role in rising knowledge gaps does not need explaining because knowledge gaps are not increasing. For polarization, the story is nuanced. Whatever evidence exists suggests that the effect is modest, but measuring long-term effects of a rapidly changing media landscape is hard and may explain the results.
As we also find, even describing trends in basic explanatory variables is hard. Current measures are beset with five broad problems. The first is conceptual errors. For instance, people frequently equate preference for information from partisan sources with a preference for congenial information. Second, survey measures of news consumption are heavily biased. Third, behavioral survey experimental measures are unreliable and inapt for learning how much information of a particular kind people consume in their real lives. Fourth, measures based on passive observation of behavior only capture a small (likely biased) set of the total information consumed by people. Fourth, content is often coded crudely—broad judgments are made about coarse units, eliding over important variation.
These measurement issues impede our ability to answer the extent to which people choose badly and the attendant consequences of such. Improving measures will do much to advance our ability to answer important questions.
The German sociologist Niklas Luhmann has provided one of the most elaborate theories of society available, as well as numerous works on specific aspects of society. Commonly labeled as “systems theory,” this is but a shorthand description of Luhmann’s theory. In fact, the theory rests on at least three main theoretical pillars. In addition to systems theory, a theory of social evolution and a theory of social differentiation play important roles. The present article introduces these three pillars and describes Luhmann’s theory of politics in this context. It outlines the crucial difference between a theory of politics as part of a theory of society on the one hand, and political theory as a reflective theory within the political system on the other hand. More specifically, it introduces Luhmann’s accounts of the notions of “political power,” “differentiation,” “the state,” “political steering,” and “the self-description of the political system.” The contribution concludes with some observations on the fact that Luhmann’s theory has tended to overlook the dimension of international politics, but that his theory provides opportunities to account for it in innovative ways.

Public service broadcasters are a central part of national news media environments in most advanced democracies. Although their market positions can vary considerably between countries, they are generally seen to enhance democratic culture, pursuing a more serious and harder news agenda compared to commercial media . . . But to what extent is this perspective supported by empirical evidence? How far can we generalize that all public service news media equally pursue a harder news agenda than commercial broadcasters? And what impact does public service broadcasting have on public knowledge? Does exposure to public service broadcasting increase citizens’ knowledge of current affairs, or are they only regularly viewed by citizens with an above average interest in politics and hard news?
The overview of the evidence provided by empirical research suggests that citizens are more likely to be exposed to hard news, and be more knowledgeable about current affairs, when they watch public service news—or rather news in media systems where public service is well funded and widely watched. The research evidence also suggests there are considerable variations between public broadcasters, just as there are between more market-driven and commercial media. An important limitation of previous research is related to the question of causality. Therefore, a main challenge for future research is to determine not only if public service broadcasting is the preferred news provider of most knowledgeable citizens, but also whether it more widely improves and increases citizens’ knowledge about public affairs.

Students of public opinion tend to focus on how exposure to political media, such as news coverage and political advertisements, influences the political choices that people make. However, the expansion of news and entertainment choices on television and via the Internet makes the decisions that people make about what to consume from various media outlets a political choice in its own right. While the current day hyperchoice media landscape opens new avenues of research, it also complicates how we should approach, conduct, and interpret this research. More choices means greater ability to choose media content based on one’s political preferences, exacerbating the severity of selection bias and endogeneity inherent in observational studies. Traditional randomized experiments offer compelling ways to obviate these challenges to making valid causal inferences, but at the cost of minimizing the role that agency plays in how people make media choices.
Resent research modifies the traditional experimental design for studying media effects in ways that incorporate agency over media content. These modifications require researchers to consider different trade-offs when choosing among different design features, creating both advantages and disadvantages. Nonetheless, this emerging line of research offers a fresh perspective on how people’s media choices shapes their reaction to media content and political decisions.
