Abstract: Abstract Group polarization is a tendency in which the mean of group decisions is shown to be more extreme than the mean of individual decisions. Though this is a stable tendency, it says very little about each group decision. In this paper, we simulated group polarization in terms of each group decision. We assumed that each group has a focal point to which every group member concentrates his/her attention. The focal point refers to a tacit understanding, concerning one, whose decision is considered to be right for the group decision. To calculate the focal point and to predict each group decision, we used the Meta-Contrast Ratio (MCR). Accumulating the predicted group decisions, we simulated group polarization.
