Using Twitter to mobilize protest action: online mobilization patterns and action repertoires in the Occupy Wall Street, Indignados, and Aganaktismenoi movements

Yannis Theocharis; Will Lowe; Jan W. van Deth; Gema García-Albacete

The extensive use of social media for protest purposes was a distinctive feature of the recent protest events in Spain, Greece, and the United States. Like the Occupy Wall Street protesters in the United States, the indignant activists of Spain and Greece protested against unjust, unequal, and corrupt political and economic institutions marked by the arrogance of those in power. Social media can potentially change or contribute to the political communication, mobilization, and organization of social movements. To what extent did these three movements use social media in such ways? To answer this question a comparative content analysis of tweets sent during the heydays of each of the campaigns is conducted. The results indicate that, although Twitter was used significantly for political discussion and to communicate protest information, calls for participation were not predominant. Only a very small minority of tweets referred to protest organization and coordination issues. Furthermore, comparing the actual content of the Twitter information exchanges reveals similarities as well as differences among the three movements, which can be explained by the different national contexts.

Young people, political participation and online postmaterialism in Greece

Yannis Theocharis

According to Inglehart’s postmaterialist theory, young people brought up in periods of high economic and physical security, surrounded by better opportunities for education, are more likely to prioritise postmaterialist values. Postmaterialists are strongly inclined to support new forms of collective action and extra-institutional activity. Internet researchers have reported that internet users are mainly young, well educated and affluent, thus denoting a similarity to the demographic characteristics of postmaterialists. This article presents some evidence regarding the existence of postmaterialist values in the online realm of Greece, attempting to demonstrate how postmaterialism influences online and offline political activity. The findings indicate a trend on the part of young people to display a postmaterialist orientation, accompanied by a disinterest in traditional forms of political participation. Postmaterialism is positively associated with internet use and is a weak contributing factor to online and offline extra-institutional participation.

Online Political Engagement, Facebook, and Personality Traits

Ellen Quintelier; Yannis Theocharis

Despite the growing literature on the effects of personality traits on political participation, there is little discussion about the potential effects of such traits on the increasingly popular forms of online political engagement. In a changing media environment where social production and exposure becomes central, people with different personality traits may be inclined to engage into forms of participation that are different from those in the offline realm. Using the “Big Five” framework, we test the effect of personality traits on various forms of online and offline political engagement in a sample of undergraduate students. Consistent with long-standing empirical observations in the offline realm, our findings show that the effects of personality traits on online forms of political engagement do not differ. Only openness to experience and extraversion have an effect on online political engagement. For consciousness, agreeableness, and emotional stability only small effects were observed.

Tweeting alone? An analysis of bridging and bonding social capital in online networks

Javier Sajuria; Jennifer vanHeerde-Hudson; David Hudson; Niheer Dasandi; Yannis Theocharis

In this article, we test Putnam’s claim that online interactions are unable to foster social capital by examining the formation of bridging and bonding social capital in online networks. Using Burt’s concepts of closure and brokerage as indicators, we observe networks formed through online interactions and test them against several theoretical models. We test Putnam’s claim using Twitter data from three events: the Occupy movement in 2011, the IF Campaign in 2013, and the Chilean Presidential Election of the same year. Our results provide the first evidence that online networks are able to produce the structural features of social capital. In the case of bonding social capital, online ties are more effective in forming close networks than theory predicts. However, bridging social capital is observed under certain conditions, for example, in the presence of organizations and professional brokers. This latter finding provides additional evidence for the argument that social capital follows similar patterns online and offline.

Stimulating citizenship or expanding entertainment? The effect of Facebook on adolescent participation:

Yannis Theocharis; Ellen Quintelier

Over the past decade, Internet and politics scholarship has been concerned with the effects of the Internet on forms of civic and political participation. Recent research has moved on to examine the effects of social networking sites like Facebook. Although past studies have generally found positive – albeit weak or moderate – relationships between social networking sites use and civic and political participation, reliance on cross-sectional surveys has not produced conclusive evidence of the direction of causality. We use a two-wave panel survey of 15- and 16-year-olds to examine how Facebook use affects various forms of political and non-political entertainment-oriented participation (both online and offline). We find that Facebook use is positively related to civic and entertainment-oriented, but not to online or offline political, participation. Further analysis using structural equation modelling shows that prior levels of civic participation have a stronger effect on Facebook use than Facebook use has on civic participation. Facebook use only leads clearly to entertainment-oriented participation. The implications of these findings are discussed.

The Conceptualization of Digitally Networked Participation

Yannis Theocharis

The conceptualization and measurement of political participation has been an issue vibrantly debated for more than 50 years. The arrival of digital media came to add important parameters to the debate complicating matters further. Digital media have added inexhaustive creative and nonpolitical ways to engage in social and political life that not only often appear to form the basis of political participation but also, in a plethora of everyday contexts, seem to become embedded into what eventually evolves to become a politically meaningful act. This article argues that digitally networked participation—and its manifestations—is a form of political participation and should be conceptualized, identified, and measured as one. Relying on recent conceptual and empirical work, it shows how various common manifestations of digitally networked participation conform to minimalist, targeted, and motivational definitions of political participation. Finally, tackling common misconceptions about the value of such acts, this article argues that nonpolitical forms of digitally networked participation can occasionally be far more impactful than forms of participation commonly accepted as political. This article concludes by recommending the systematic development of measures for digitally networked participation and its formal integration in the study of political participation.

The continuous expansion of citizen participation: a new taxonomy

Yannis Theocharis; Jan W. van Deth

The repertoire of political participation in democratic societies is expanding rapidly and covers such different activities as voting, demonstrating, volunteering, boycotting, blogging, and flash mobs. Relying on a new method for conceptualizing forms and modes of participation we show that a large variety of creative, expressive, individualized, and digitally enabled forms of participation can be classified as parts of the repertoire of political participation. Results from an innovative survey with a representative sample of the German population demonstrate that old and new forms are systematically integrated into a multi-dimensional taxonomy covering (1) voting, (2) digitally networked participation, (3) institutionalized participation, (4) protest, (5) civic participation, and (6) consumerist participation. Furthermore, the antecedents of consumerist, civic, and digitally networked participation, are very similar to those of older modes of participation such as protest and institutionalized participation. Whereas creative, expressive, and individualized modes appear to be expansions of protest activities, digitally networked forms clearly establish a new and distinct mode of political participation that fits in the general repertoire of political participation.

Does Facebook increase political participation? Evidence from a field experiment

Yannis Theocharis; Will Lowe

ABSTRACT During the last decade, much of political behaviour research has come to be concerned with the impact of the Internet, and more recently social networking sites such as Facebook, on political and civic participation. Although existing research generally finds a modestly positive relationship between social media use and offline and online participation, the majority of contributions rely on cross-sectional data, so the causal impact of social media use remains unclear. The present study examines how Facebook use influences reported political participation using an experiment. We recruited young Greek participants without a Facebook account and randomly assigned a subset to create and maintain a Facebook account for a year. In this paper we examine the effect of having a Facebook account on diverse modes of online and offline participation after six months. We find that maintaining a Facebook account had clearly negative consequences on reports of offline and online forms of political and civic participation.

A Bad Workman Blames His Tweets? The Consequences of Citizens’ Uncivil Twitter Use When Interacting with Party Candidates

Yannis Theocharis; Pablo Barberá; Zoltán Fazekas; Sebastian Adrian Popa; Olivier Parnet

The recent emergence of microblogs has had a significant effect on the contemporary political landscape. The platform’s potential to enhance information availability and make interactive discussions between politicians and citizens feasible is especially important. Existing studies focusing on politicians’ adoption of Twitter have found that far from exploiting the platform’s two-way communication potential, they use it as a method of broadcasting, thus wasting a valuable opportunity to interact with citizens. We argue that citizens’ impolite and/or uncivil behaviour is one potential explanation for such decisions. Social media conversations are rife with trolling and harassment practices and politicians are often a prime target for such behaviour, a phenomenon altering the incentive structures of engaging in dialogue on social media. To demonstrate this claim, we use all Spanish, Greek, German and UK candidates’ tweets sent during the run-up to the recent EU election, along with the responses they elicited, and rely on automated text analysis and machine learning methods to measure their level of civility. Our contribution is an actor oriented theory of the political dialogue that incorporates the specificity of the social media platform, further clarifying how and why democratic promises of such social media platforms are fulfilled or limited.

From Liberation to Turmoil: Social Media And Democracy

Joshua A. Tucker; Yannis Theocharis; Margaret E. Roberts; Pablo Barberá

Abstract: How can one technology—social media—simultaneously give rise to hopes for liberation in authoritarian regimes, be used for repression by these same regimes, and be harnessed by antisystem actors in democracy? We present a simple framework for reconciling these contradictory developments based on two propositions: 1) that social media give voice to those previously excluded from political discussion by traditional media, and 2) that although social media democratize access to information, the platforms themselves are neither inherently democratic nor nondemocratic, but represent a tool political actors can use for a variety of goals, including, paradoxically, illiberal goals.
