Opinion dynamics theory considering interpersonal relationship of trust and distrust and media effects

Abstract

Bounded Confidence Model is well-known for opinion dynamics theory that considers opinions as continuous values. However, this does not include confrontation of people. In this paper, we express a theory which expresses the relation of trust and distrust between people by the sign of interpersonal relationship coefficient and extends the value of opinion on one dimensional axis from positive to negative. In addition, the influence on the mass media was also taken into consideration, and efforts were made to consider. In this paper, we will show examples of 2, 3, 20 and 300 people in computational simulation. The distribution of opinions calculated from this calculation may be comparable to the distribution of opinions measured on social networks.
