The inhibition effect: Privacy concerns disrupt the positive effects of social media use on online political participation

The literature on the relationship between social media and online political participation continues to expand. Yet, attention to the effect of cognitive dispositions central to user engagement on social media is rare. This study advances the current theoretical understanding of the effects of social media news use by focusing on online privacy concerns. Two studies in Singapore (Study 1 using cross-sectional survey data) and the United States (Study 2 using two-wave panel data) find that social media news use is positively associated with online political participation. Still, public concern regarding online privacy is negatively related to online political participation. Moreover, moderation analyses suggest that those with more significant privacy concerns are least likely to engage in online political participation, even at higher social media news use levels. We also identify that those with lower cognitive ability are more likely to curb online participation due to privacy concerns.
