Abstract An opinion evolution model without bounded confidence is proposed in this paper. Computer simulation shows that our model can figure out the breakage of the coexistence of majority and minority after a period s evolution. With further analysis, our model shows that, without the influence of the external field, the opinions will finally die out to a limited small value no matter what the initial condition of the system is. On the other hand, we simulate the evolution of the opinions under the influence of an external field, and get some meaningful and instructional results.
