Abstract

This study investigates two competing opinions regarding the role of social media platforms in partisan polarization. The “echo chambers” view focuses on the highly fragmented, customized, and niche-oriented aspects of social media and suggests these venues foster greater political polarization of public opinion. An alternative, which we term the “crosscutting interactions” view, focuses on the openness of the Internet and social media, with different opinions just a click away. This view thus argues that polarization would not be especially problematic on these outlets. Exploiting the variation among members of the U.S. House of Representatives in measured positions of political ideology, this study estimates the association between politicians’ ideological positions and the size of their Twitter readership. The evidence shows a strong polarization on Twitter readership, which supports the echo chambers view. Lastly, we discuss the implications of this evidence for governments’ use of social media in collecting new ideas and opinions from the public.

Keywords: social media, Twitter, U.S. House of Representatives, political polarization, political ideology
