The emergence of social networking sites (SNSs) allows users to encounter diverse political perspectives. However, it also makes it easy for people to stay within the “echo chambers,” giving rise to political polarization. Research about political polarization is critical because scholars argue that polarized political attitudes may threaten democracy. This study hypothesized that exposure to heterogeneous information was positively associated with political polarization. Specifically, the attitudinal and affective polarization were both examined. Using the 2018 dataset from Taiwan Institute for Governance and Communication Research (TIGCR), the study found that exposure to heterogeneous information is a significant positive predictor of attitudinal polarization towards Democratic Progressive Party (DPP). In addition to the main effect, the indirect path from exposure to heterogeneous information to political polarization through political persuasion is identified. Moreover, the results also indicate a significant moderation effect of selective avoidance. The effect of exposure to heterogeneous information on political persuasion is weaker for those SNSs users who avoid opposing political views more frequently. The findings suggest that how SNSs users process heterogeneous information and their selective behaviors on SNSs can influence the role SNSs play in shaping people’s political polarization.
