We estimated ideological preferences of 3.8 million Twitter users and, using a data set of nearly 150 million tweets
concerning 12 political and nonpolitical issues, explored whether online communication resembles an “echo chamber”
(as a result of selective exposure and ideological segregation) or a “national conversation.” We observed that information
was exchanged primarily among individuals with similar ideological preferences in the case of political issues (e.g.,
2012 presidential election, 2013 government shutdown) but not many other current events (e.g., 2013 Boston Marathon
bombing, 2014 Super Bowl). Discussion of the Newtown shootings in 2012 reflected a dynamic process, beginning as
a national conversation before transforming into a polarized exchange. With respect to both political and nonpolitical
issues, liberals were more likely than conservatives to engage in cross-ideological dissemination; this is an important
asymmetry with respect to the structure of communication that is consistent with psychological theory and research
bearing on ideological differences in epistemic, existential, and relational motivation. Overall, we conclude that
previous work may have overestimated the degree of ideological segregation in social-media usage.
