Online bandwagon effects: Quantitative versus qualitative cues in online comments sections

Bandwagon effects explain an individual’s tendency to conform to and follow other people’s opinions. Drawing on bandwagon effects, this study explored the relative influence of two different bandwagon heuristic cues in an online comments section (quantitative vs qualitative) on changes in news readers’ opinion. Study 1 revealed that qualitative cues have a stronger effect than quantitative cues in changing news readers’ opinions. Study 2 replicated the findings of Study 1 and showed that people change opinions in the same direction as perceived public opinion, providing empirical evidence of online bandwagon effects. The findings offer theoretical insights by explicating the process of opinion change via perceived public opinion as well as practical insights into public opinion formation in online environments.
