“…Although there are theoretical reasons to predict a link between the selection of likeminded media outlets and polarized attitudes, the empirical evidence to date is inconclusive. First, although a number of studies have found evidence of a link between media exposure and polarization (Adams et al, 1985; Bimber & Davis, 2003; Druckman & Parkin, 2005; Jones, 2002; Lavine, Borgida, & Sullivan, 2000; Mendelsohn & Nadeau, 1996; Stroud, 2007; Taber & Lodge, 2006), there are exceptions where scholars have found no evidence of polarization (see, e.g., Ball‐Rokeach, Grube, & Rokeach, 1981; Paletz, Koon, Whitehead, & Hagens, 1972) or where scholars have raised questions about whether likeminded media exposure enhances polarization (Meffert, Chung, Joiner, Waks, & Garst, 2006). Second, none of the studies to date have attempted to consider people's media exposure patterns comprehensively.…”
