ABSTRACT Languages constantly change. This requires variants that are initially rare to become dominant. A prime question is how such changes come about. Here we propose that the inter-connectivity of people’s contacts, and people’s failure to take it into account leads them to over-weigh the informativity of repeated information. In Experiment 1 we find that people do not sufficiently account for the independence of their sources, and that this neglect is stronger for linguistic terms than it is for opinions. In Experiment 2 we conduct simulations on real world networks and find that failure to account for source dependence promotes the spread of innovations. Together, these results show that language and opinions do not follow the same trajectory of change, and that the spread of innovations, and especially linguistic innovations, is facilitated by biases in the way we process information and community structure.

注意到我们的社交网络如何相互关联会影响语言变化

摘要 语言不断变化。这需要最初很少见的变体成为优势。一个主要问题是这些变化是如何发生的。在这里，我们提出人们接触的相互联系，以及人们未能将其考虑在内，导致他们过度重视重复信息的信息性。在实验 1 中，我们发现人们没有充分考虑其来源的独立性，并且这种忽视对于语言术语比对意见更强烈。在实验 2 中，我们对现实世界的网络进行了模拟，发现未能考虑到来源依赖会促进创新的传播。总之，这些结果表明语言和观点并不遵循相同的变化轨迹，而且创新的传播，尤其是语言创新，
