论文摘要
观点是我们如何看待世界和彼此的观点的组成部分。他们塑造集体行动，在民主进程，规范的演变和文化变革中发挥作用。几十年来，社会和自然科学领域的研究人员一直试图描述各个个人观点和社会交流如何导致诸如共识和两极分化之类的公众舆论的原型状态。在这里，我们回顾了对该领域的众多贡献，既专注于理想化的意见动态模型，并尝试通过观察数据和受控的社会学实验来验证它们。通过进一步缩小模型和数据之间的差距，这些努力可能有助于我们了解如何面对当前的挑战，这些挑战需要在复杂的情况下（例如经济不平等，气候变化以及社会政治格局的持续断裂）达成一致的挑战。
Opinions are an integral part of how we perceive the world and each other. They shape collective action, playing a role in democratic processes, the evolution of norms, and cultural change. For decades, researchers in the social and natural sciences have tried to describe how shifting individual perspectives and social exchange lead to archetypal states of public opinion like consensus and polarization. Here we review some of the many contributions to the field, focusing both on idealized models of opinion dynamics, and attempts at validating them with observational data and controlled sociological experiments. By further closing the gap between models and data, these efforts may help us understand how to face current challenges that require the agreement of large groups of people in complex scenarios, such as economic inequality, climate change, and the ongoing fracture of the sociopolitical landscape.
