Exposure to conflicting political viewpoints is widely assumed to benefit the citizens of a democratic polity. Nonetheless, the benefits of exposure to heterogeneous political viewpoints have yet to be demonstrated empirically. Drawing on national survey data that tap characteristics of people's political discussion networks, I examine the impact of heterogeneous networks of political discussion on individuals' awareness of legitimate rationales for oppositional viewpoints, on their awareness of rationales for their own viewpoints, and on levels of political tolerance. Finally, utilizing a laboratory experiment manipulating exposure to dissonant and consonant political views, I further substantiate the causal role of cross-cutting exposure in fostering political tolerance.

We use national survey data to examine the extent to which various sources of political information expose people to dissimilar political views. We hypothesize that the individual's ability and desire to exercise selective exposure is a key factor in determining whether a given source produces exposure to dissimilar views. Although a lack of diverse perspectives is a common complaint against American news media, we find that individuals are exposed to far more dissimilar political views via news media than through interpersonal political discussants. The media advantage is rooted in the relative difficulty of selectively exposing oneself to those sources of information, as well as the lesser desire to do so, given the impersonal nature of mass media.
