Intermediate State of Consensus Formation Described by the Tri-Molecular Model

Consensuses are essential for a society to run well. The description of consensuses formation is a hot spot for interdisciplinary study. Based on the tri-molecule model, this paper investigated the intermediate state of a group from diffidence to confidence. The model emphasizes the different influences from the internal and the external environments. The former, for one individual, refers to collisions with the others in the group while the latter refers to impacts from the outside of the group. The investigation reveals three variation modes for the intermediate state under different transition ratios and different diffusion modes of the individuals. One variation mode is stable, and the others are unstable. The stable transition mode appears under the condition that the influence from the external environment is stronger than that from the internal environment, which may be realistically observable. This implies that the formation of social consensuses needs some strong external actions, such as advocating, publicizing, training and educating, conducted by the government and others.
