Why Social Media Matter
To understand how social media can contribute to political participation, research must first investigate the extent to which individuals experience political content on these platforms. Second, we need to understand whether and how these experiences and their effects differ among different types of users—such as those with different levels of political involvement and different ideological preferences. Finally, we need to know how these relationships are shaped by systemic factors that vary across countries—such as patterns of electoral competition, characteristics of media systems, and the strength of party organizations. The theoretical framework presented in this chapter overcomes three theoretical and empirical fallacies that have limited researchers’ ability to understand the relationship between social media and political participation. These fallacies inaccurately suggest that platforms’ affordances are a destiny that inevitably shapes outcomes, that the effects of social media are uniform among different groups of users rather than varying based on their specific characteristics, and that contextual features and systemic factors do not play any relevant role.
