我们引入了一种新型的反向代理，平衡器，意见动态的Galam模型，其特点是群体多数更新，以占社会怀疑论的片面性的存在。我们发现，沿着，随着多数浮动和单边浮动，包括平衡，谁通常作为浮动，但反对浮动在他们的存在，带来了动力系统的参数平面上的临界点的出现。在临界点附近，发现了三个由不连续变化分开的意见动态的不同阶段。（C）2015 Elsevier B.V.保留所有权利。
We introduce a novel type of contrarian agent, the balancer, to the Galam model of opinion dynamics, which features group-majority update, in order to account for the existence of social skepticism over one-sidedness. We find that, along with majoritarian floaters and single-sided inflexibles, the inclusion of balancers, who normally act as floaters but oppose inflexibles in their presence, brings about the emergence of a critical point on parametric plane of the dynamical system. Around the critical point, three distinct phases of opinion dynamics separated by discontinuous changes are found. (C) 2015 Elsevier B.V. All rights reserved.
