How Accurate Are Survey Responses on Social Media and Politics?

How accurate are survey-based measures of social media use, in particular about political topics? We answer this question by linking original survey data collected during the U.S. 2016 election campaign with respondents’ observed social media activity. We use supervised machine learning to classify whether these Twitter and Facebook account data are content related to politics. We then benchmark our survey measures on frequency of posting about politics and the number of political figures followed. We find that, on average, our self-reported survey measures tend to correlate with observed social media activity. At the same time, we also find a worrying amount of individual-level discrepancy and problems related to extreme outliers. Our recommendations are twofold. The first is for survey questions about social media use to provide respondents with options covering a wider range of activity, especially in the long tail. The second is for survey questions to include specific content and anchors defining what it means for a post to be “about politics.”     

Toward a measurement tool for the monitoring of media diversity and pluralism in South Africa: A public-centred approach

Abstract

This article responds to recent debates within South African media politics regarding the diversity and transformation of the print sector in the country, by suggesting a necessary refocus of previously used methods of measuring media diversity and proposing a more audience-centred approach. This audience-centred method is discussed with regard to meeting the demands of the normative understanding of media diversity, where the media are viewed as central to an individual's formulation of opinions and ideas, thus rendering the media – and particularly the news media – vital in fostering an enabled and informed citizenry. The argument proposes a bottom-up instead of a top-down methodology for measuring media diversity, by placing the primary focus on the public as the starting point, rather than the end point of the analysis, and validating this position through the normative view of the media's role in assisting citizens to formulate personal views. The article concludes by listing four key areas in which current debates on media diversity in South Africa should be realigned and refocused, including at a parliamentary level.     

Differential Online Exposure to Extremist Content and Political Violence: Testing the Relative Strength of Social Learning and Competing Perspectives

The present study applies Social Learning (Differential Association) Theory to the explanation of political violence, focusing on exposure to extremist content through new social media (NSM) and controlling for key variables derived from rival theories. Data are gathered using (a) a paper-and-pencil study among high school students, and (b) a web survey targeting youths between 16 and 24 years old. A total of 6020 respondents form the dataset. Binary logistic regression is used to analyze the data. Results show that even when controlling for background variables, strain variables, personality characteristics, moral values, and peer influences, the statistical association between measures of extremism through NSM (ENSM) and self-reported political violence remains significant and fairly constant. The most persistent effects are found for those measures where individuals actively seek out extremist content on the Internet, as opposed to passive and accidental encounters using NSM. Furthermore, offline differential associations with racist and delinquent peers are also strongly and directly related to self-reported political violence, as are some mechanisms from rival perspectives. This indicates that political violence can only partially be explained by social learning and suggests that the impact of ENSM is mediated by real-world associations and that the offline world has to be taken into account.

Terrorism and the media: Problems,solutions, and counterproblems

This article is divided into two main parts. The first part frames the problem of “terrorism and the media” in terms of a complex interaction involving three kinds of relationships. The first is the relationship between terrorists and governments; the second is the relationship between terrorists and the media; and the third is the relationship between government and the media. The second part examines the specific roles of the media in covering terrorism and the impact of such coverage. Four kinds of solutions to the problems deriving from this impact are examined in turn: the use of media guidelines, the use of legislation and legal sanctions, media‐government cooperation, and training and education. Finally, the practicality of these solutions is examined by highlighting the kinds of problems or “counterproblems” that are inherent in each solution.
