Most research on computer-mediated cross-cutting political exchanges looks at social network homophily and selective exposure—assuming cross-cutting exposure’s deliberative outcomes. Little research analyses the patterns of exchanges under various conditions, and their distinct attitudinal outcomes. Thus, this review investigates how individuals adapt to different conversational norms in front of different online audiences when engaging in cross-cutting political discourse, highlighting that, although political identities are powerful, they are fluid and may vary from context to context. An Ordinary Least Squares Regression Analysis was conducted to examine the association between sharing an additional salient identity, beyond political identity, on political attitude reinforcement and online political expressions. Cross-cutting exchanges generally occur in casual settings online--where a second shared identity, beyond political ideology, is present. A second salient, shared identity may incentivize individuals to deviate from political identity norms, as a self-presentation tactic. The results should assist scholars in understanding the varying influence of political identities in cross-cutting exchanges, and their attitudinal outcomes in the context of political polarization. Scholars should, however, carefully evaluate the effects of cross-cutting exchanges on democratic participation when considering their deliberative effects.
