是什么维持了文化多样性，又是什么破坏了它？阿克塞尔罗德和超越
What sustains cultural diversity and what undermines it? Axelrod and beyond
摘要：
我们放宽了阿克塞尔罗德（1997）的文化传播模型的简化，尚未被研究，假设所有的文化国家是名义上的。我们将度量状态集成到原始模型中。计算实验表明，即使没有噪音，度量状态也会通过在代理之间创建足够的重叠来相互影响，从而破坏文化多样性。然后，我们将展示如何添加“有限的信心”-最近的创新模型的社会影响力-允许文化多样性持续存在。然而，进一步的实验表明，该解决方案是脆弱的。多样性可以维持只有一个相对较小的数量的度量状态，低水平的噪声或窄的置信区间。
英文摘要：
We relax a simplification of Axelrod's (1997) model of cultural dissemination that has not yet been studied, the assumption that all cultural states are nominal. We integrate metric states into the original model. Computational experiments demonstrate that metric states undermine cultural diversity, even without noise, by creating sufficient overlap between agents for mutual influence. We then show how adding "bounded confidence" - a recent innovation in models of social influence - allows cultural diversity to persist. However, further experiments reveal that the solution is fragile. Diversity can be sustained only with a relatively small number of metric states, low levels of noise or narrow confidence intervals.
