Since the mid-20th century, communication researchers have recognized that audience members selectively expose themselves to information and opinions congenial to their pre-existing views. While this was a controversial idea during the broadcast era of mass media, the expansion of media choice on television and use of information communication technology has brought increased attention to selectivity among audience members. Contemporary scholarship investigates the extent to which people select proattitudinal information or avoid counterattitudinal information and the role these choices play in the effects of media messages on viewers.
While selective exposure is a broader phenomenon, this article substantively focuses on the use of politically partisan media, especially the research methods used to investigate media selectivity and its effects. This literature manifests an increased attention to measurement, especially how we measure the core concept of media exposure, novel experimental designs intended to allow investigators to directly view individual choice behavior in complex media environments, and attention to new sources of large-scale data from social media and large text samples.
Scholars agree that partisan websites and cable networks provide content politically distinct enough to allow viewers to segregate themselves into liberal and conservative audiences for news but that this kind of polarized viewing is only part of how viewers use media today. A nuanced picture of selectivity shows audiences selecting congenial content but employing broader media use repertoires as well. The mechanisms and effects of media selectivity are psychologically complex and sensitive to contextual factors such as the political issue under consideration.
The spiral of silence theory provides insight into the ways in which perceptions of public opinion can lead to changes in opinion expression behavior. Conceptualized in a political communication context, the central claim of the theory is that individuals’ fear of social isolation motivates them to continuously evaluate the climate of opinion through both experiences with the media and interpersonal communication. Upon assessment, individuals either find themselves in a situation where their opinion aligns with the majority or minority. Accordingly, those who find their opinion does not align with the dominant opinion are likely to conceal their opinions while those who find their opinion aligns with the majority are more likely to express them.
Empirical research testing the spiral of silence theory has predominately focused on measurement of focal variables and methods of empirical testing. Advances have been made in regard to micro-level factors, such as creating universally applicable measures of psychological attributes. However, limited work has explored macro-level factors, such as appropriateness of issues, application to computer-mediated communication environments, and tools used to identify circumstances vulnerable to spiral of silence effects. Nonetheless, the practical value of the spiral of silence theory for health and risk communicators can be utilized by modifying campaign efforts to anticipate and counteract fluxes in public opinion.

Depending on how you approach it, economic justice is either an extremely old intellectual tradition or a relatively new one. From the first perspective, economic justice is part and parcel of classical political philosophy—Plato’s The Republic and Aristotle’s The Politics, for instance, both discuss property distribution in an ideal society, emphasizing the philosophy of justice over economic precepts. From the second perspective, the one we embrace, economic justice is a uniquely modern inquiry that emerged with the writings of Karl Marx and his revolutionary critique of the capitalist political economy. For Marx, economic justice can be understood as a critical enterprise that attempts to locate contradictions between universal and particular conceptions of human freedom and intervene politically into these contradictions with the aim of creating a more just, equitable, and egalitarian society. So conceived, economic justice liberates the collective potential of humanity from its exploitation and degradation by capitalism as well as the various legal institutions it develops to control human behavior for the purpose of extracting of surplus-value. It is this Marxist perspective and the various historical reformulations that it has authorized that influence the way rhetoricians and scholars of cultural studies conceptualize economic justice in the discipline of communication. While not all of these scholars endorse an explicitly Marxist line of thought, they all attempt to conceptualize economic justice as a normative political category that influences various models of rhetorical agency and social change.
