Scholars have advanced many theoretical explanations for expecting a negative or positive relationship between individuals' cross-cutting exposure-either through interpersonal or mediated forms of communication-and their political participation. However, whether cross-cutting exposure is a positive or negative predictor of participation is still an unsettled question. To help fill this gap, we conducted a meta-analysis of 48 empirical studies comprising more than 70,000 participants examining the association between cross-cutting exposure and political participation. The meta-analysis produced two main findings. First, it shows that, over all studies, there is no significant relationship, r = .002, Zr = .002 (95% CI = −.04 to .05). Second, the null relationship cannot be explained by variations in the characteristics of cross-cutting environments (e.g., topic, place, or source of exposure), participation outcomes (e.g., online vs. offline activities), or methods employed (e.g., experiment vs. survey). Taken together, these results should alleviate concerns about negative effects of cross-cutting exposure on political engagement. Implications for future research are discussed.Keywords disagreement, political participation, cross-cutting exposure, political discussion, meta-analysis One of the most studied aspects in contemporary political communication research refers to cross-cutting exposure, that is, the disagreement in viewpoints encountered by individuals in their communication environments. Whether through informal conversations or media use, scholars have found support for the many extolled virtues of exposure to disagreeable political opinions. To name just a few, it has been found that encountering disagreement increases individuals' tolerance (Pattie & Johnston, 2008), Jörg Matthes is professor of communication science and Chair of the Department of Communication, University of Vienna.
