Why Majorities Are Silent but Minorities Are Loud: An Empirical Approach to Opinion Interactions in Online Communities

Abstract

Majority opinions are often observed in online environments. Previous studies have demonstrated that majority opinions are constructed because people with minority opinions have fear of isolation, which forces them to be silent. However, we often observe that online users with different minority opinions fight each other, even though there are only a few. To explain this phenomenon, we developed a new theoretical model and examined it through the analysis of Reddit data. The results show that users in small communities expressed relatively homogeneous and less negative opinions, and constructed majority opinions that were not as strong as those in large communities. Contrarily, users in large communities showed relatively heterogeneous and more negative opinions, and built majority opinions more strongly than those in small communities. This implies that the model can properly explain why and how majority-opinion users are silent and why minority-opinion users are loud.
