| Abstract: | Social media could serve as an easy and fast window to the climate of public opinion. In the current study, we examined the influence of perceived opinion climate revealed via Twitter postings in shaping televised debate viewers’ candidate evaluation. We conducted two Web-based experiments in the high- and low-stimulus elections: (a) the 2012 Korean presidential election and (b) the 2014 Seoul mayoral election. Instead of using contrived stimulus materials, we were able to examine the influence of exposure to Twitter postings in voters’ judgment of candidate performance in real time. Using a custom-designed Web application, participants evaluated the candidates as debate-related Twitter postings were being fed in real time during each televised debate. Our results suggest that exposure to Twitter postings has induced significant bandwagon effects. Bandwagon effects were pervasive even among partisans and the knowledgeable. Our findings show that more policy efforts ought to be made to strengthen the informative role of social viewing. |
