观点动力学的纠结世界观模型
Tangled Worldview Model of Opinion Dynamics
摘要：
我们通过提出一个观点动力学模型来研究世界观的联合进化，这个模型受到进化生态学概念的启发。代理人根据他们的改变倾向（由社会邻居断言）更新他们对特定问题的看法，并根据他们在其他问题上的相互相似性进行加权。因此，代理人更容易受到具有相似世界观（对各种问题的观点集）的邻居的影响，导致每个观点的复杂共同进化。模拟结果表明，当社会网络是无标度的世界观演化表现出间歇性极化事件。这反过来又引发了各种观点的极端崩溃和流行。使用所提出的模型，我们突出的作用，网络结构，有限理性的代理，和关键的影响力代理在无标度网络的世界观的极化和间歇性改革的作用。
英文摘要：
We study the joint evolution of worldviews by proposing a model of opinion dynamics, which is inspired in notions from evolutionary ecology. Agents update their opinion on a specific issue based on their propensity to change -- asserted by the social neighbours -- weighted by their mutual similarity on other issues. Agents are, therefore, more influenced by neighbours with similar worldviews (set of opinions on various issues), resulting in a complex co-evolution of each opinion. Simulations show that the worldview evolution exhibits events of intermittent polarization when the social network is scale-free. This, in turn, trigger extreme crashes and surges in the popularity of various opinions. Using the proposed model, we highlight the role of network structure, bounded rationality of agents, and the role of key influential agents in causing polarization and intermittent reformation of worldviews on scale-free networks.
