Political discussion networks are influenced by the opportunities for political interactions within our larger social environments and more general discussion networks. In this study we compare general and political discussion networks using full sociometric social network data from a probability sample of voluntary organizations-specifically, intact student activity groups from a large Midwest research university. We find that even within these "weak tie" voluntary associations, general discussion networks clearly constrain the characteristics of the political discussion networks. However, political discussion networks appear to be less dense and more likely to be broken up into disconnected components than the general discussion networks. But, general and political networks do not appear to differ in their structuring by perceptions of discussant knowledge. And, most interestingly, we find that on average neither general nor political discussion networks are characterized by political homogeneity. Adapted from the source document.

The glut of media coverage prior to a presidential election requires individuals to selectively expose themselves to some messages and not others. The study involves a two-session online quasi-experiment with 205 participants that was conducted before the 2008 presidential election. Hypotheses on confirmation bias and information utility driving selective exposure prior to an election are tested. Results confirm that information utility can override a confirmation bias and motivate exposure if a government change is likely and the favored party is likely to lose the election. Moreover, participants with frequent habitual online news use do not exhibit a confirmation bias. However, participants whose favored party was likely to win the election and participants with infrequent online news consumption show a significant confirmation bias.
