The spread of agents’ opinions and beliefs have so far been studied independently. However, it can be expected that opinions and beliefs influence each other. Fukuro’s goal is to consider how they are related and this relation’s influence on their propagation in a population. For that purpose, we propose to model the connection between opinions and beliefs by two cognitive operations –opinion formation and belief alignment– guided by values held by agents. The two procedures are tightly connected to classical opinion dynamic and belief revision operations used for propagation. The proposed model will be simulated under various conditions and a sensitivity analysis performed on their influence on the amplitude of change in beliefs and opinions (stability) and the distance between beliefs or opinions (polarisation/convergence). Moreover, this model will be to determine the influence of this scheme on the propagation of minority opinions and development of “echo chambers”.
