Competition of Social Opinions on Two Layer Networks

Social conflict usually can be investigated based on the competition of two-layers network. In this paper, a competition model is studied on interconnected networks with two-layer opinions, where the first layer is opinion formation and the second layer is decision making. Starting with a polarized competition case where layer A has all the positive opinion and layer B has all the negative opinion, competition simulations are considered with different network structures. With Monte Carlos simulations, different structural models are compared with average state and consensus ratio, which shows that both internal and external links play a vital role for consensus. Especially, increasing the number of external and internal links on one side layer make it easy to reach consensus. However, too many internal edges on each layer make it hard to reach consensus due to inner conflict.
