Understanding Norm Change: An Evolutionary Game-Theoretic Approach (Extended Version)
Soham De, Dana S. Nau, Michele J. Gelfand

TL;DR
This paper introduces an evolutionary game-theoretic model to analyze how social norms emerge and change, focusing on the influence of coordination needs, cultural inertia, and exploration rates through analytical and simulation methods.
Contribution
It presents the first model linking norm strength, cultural inertia, and exploration rate, providing insights into the evolutionary dynamics of social norm change.
Findings
High need for coordination results in high cultural inertia.
Low need for coordination leads to high exploration rates.
The model reveals causal relationships among norm strength, inertia, and exploration.
Abstract
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…
