世界各地的人类社会通过发展和维护社会规范而相互作用，了解这些规范是如何产生和变化的至关重要。在这项工作中，我们定义了一个进化博弈论模型来研究社会中规范如何变化，基于社会中不同强度的规范转化为不同的博弈论互动结构和激励的想法。我们使用这个模型，通过分析和广泛的基于主体的模拟，研究社会中协调需求（与其规范强度有关）与规范变化的两个关键方面的进化关系：文化惯性（当面临需要规范变化的条件时，群体是否或多快做出反应）和探索率（代理尝试新策略的意愿）。研究结果表明，高协调需求导致高文化惯性和低勘探率，而低协调需求导致低文化惯性和高勘探率。据我们所知，这是第一次了解这些因素之间的进化因果关系。
Human societies around the world interact with each other by developing and maintaining social norms, and it is critically important to understand how such norms emerge and change. In this work, we define an evolutionary game-theoretic model to study how norms change in a society, based on the idea that different strength of norms in societies translate to different game-theoretic interaction structures and incentives. We use this model to study, both analytically and with extensive agent-based simulations, the evolutionary relationships of the need for coordination in a society (which is related to its norm strength) with two key aspects of norm change: cultural inertia (whether or how quickly the population responds when faced with conditions that make a norm change desirable), and exploration rate (the willingness of agents to try out new strategies). Our results show that a high need for coordination leads to both high cultural inertia and a low exploration rate, while a low need for coordination leads to low cultural inertia and high exploration rate. This is the first work, to our knowledge, on understanding the evolutionary causal relationships among these factors.
