连续意见和离散行动模型中的一个中间选项
A middle option for choices in the Continuous Opinions and Discrete Actions model
摘要：
对极端主义出现的条件进行建模是一个非常重要的问题，在描述个人之间的相互作用方面有着明确的应用。传统模型要么不适合这项任务，就像离散模型一样，要么像有界置信模型一样，建立的规则使观点倾向于代理之间的共同点，或者根本不改变。连续意见和离散行动（CODA）模型使我们能够观察到极端主义代理人的出现，即使每个代理人最初都是温和的，由于局部影响效应。在本文中，极端主义的出现的问题将通过在CODA模型中引入中间离散选项来解决，使其类似于Potts模型。我们将讨论第三种选择的不同情况：当它相当于保留判断时，当它是真正的第三种选择时，当它是真正的中间选择时。将研究对意见的影响，并讨论其对极端主义的影响。保留判断似乎有一个意想不到的效果，从长远来看，会导致温和意见的减少。对于中心第三意见，我们发现，在特定条件下，这种新的选择可以作为极端选择之间的缓冲。
英文摘要：
Modeling the conditions for the emergence of extremism is a very important problem, with clear applications for describing the interaction among individuals. Traditional models either are not suited for the task, as in the case of discrete models, or, like Bounded Confidence models, are built with rules that make opinions tend to a common ground between agents or not change at all. Continuous Opinions and Discrete Actions (CODA) model allowed us to observe the emergence of extremist agents, even when every agent was initially a moderate, due to local influence effects. In this paper, the problem of emergence of extremism will be addressed by introducing a middle discrete option in the CODA model, making it similar to a Potts model. Different scenarios for the third option will be discussed: when it is equivalent to withholding judgment, when it is a real third option and when it is a real, middle option. The effects on the opinions will be studied and its effects on extremism discussed. Withholding judgment seems to have an unexpected effect, causing the diminishing of moderate opinions in the long run. For a central third opinion, we find that, under specific conditions, this new choice can act as a buffer between the extreme choices.
