摘要
We investigate majority rule dynamics in a 族群 with two classes of people, each with two opinion states +/- 1, and with tunable interactions between people in different classes. In an update, a randomly selected group adopts the majority opinion if all group members belong to the same class; if not, majority rule is applied with rate epsilon. Consensus is achieved in a time that scales logarithmically with 族群 size if epsilon >= epsilon(c) = 1 9. For epsilon < epsilon(c), the 族群 can get trapped in a polarized state, with one class preferring the +1 state and the other preferring -1. The time to escape this polarized state and reach consensus scales exponentially with 族群 size.
