利用扩散反应模型研究了公众辩论（改革提案、行为改变、军事报复）中少数意见的传播动态。人们在由社会生活（办公室、住宅、酒吧和餐馆）塑造的随机几何景观上以离散的步伐移动。一个完美的世界被认为对少数人没有好处。一个人一个论点的原则是适用于确定局部个人的思想变化。在平等的情况下，引起了集体的怀疑，这反过来又有利于现状。从一个大的赞成的建议最初的多数，重复的随机大小的地方讨论被发现驱动多数逆转沿着少数人的敌意的看法。全部意见拒绝在几天内完成。最近的国家集体问题被重新审视。该模型可以应用于谣言和恐惧传播。
The dynamics of spreading of the minority opinion in public debates (a reform proposal, a behavior change, a military retaliation) is studied using a diffusion reaction model. People move by discrete step on a landscape of random geometry shaped by social life (offices, houses, bars, and restaurants). A perfect world is considered with no advantage to the minority. A one person-one argument principle is applied to determine locally individual mind changes. In case of equality, a collective doubt is evoked which in turn favors the Status Quo. Starting from a large in favor of the proposal initial majority, repeated random size local discussions are found to drive the majority reversal along the minority hostile view. Total opinion refusal is completed within few days. Recent national collective issues are revisited. The model may apply to rumor and fear propagation.
