Under certain mild conditions,the existence of a few rebels will lead the group opinion to the golden mean,regardless of the initial opinions of the agents and the structure of the learning *** result is completely different from that of the standard DeGroot model,where the final consensus opinion is determined by both the initial opinions and the learning *** study then provides new insights into understanding how heterogeneous individuals in a group reach consensus and why the golden mean is so common in human society.
