Beyond the Centralized Mindset

Abstract In recent years, there has been a growing fascination with decentralized systems and self-organizing phenomena. Increasingly, people are choosing decentralized models for the organizations and technologies that they construct in the world and for the theories that they construct about the world. However, even as decentralized ideas spread through the culture, there is a deep-seated resistance to such ideas. In trying to understand patterns in the world, people often assume centralized control where none exists (e.g., assuming that a "leader bird" guides the rest of the flock). To probe how people think about decentralized systems and to help them develop new ways of thinking about such systems, I developed a programmable modeling environment called StarLogo with which people can easily create and experiment with decentralized systems. StarLogo allows users to control the actions and interactions of thousands of artificial creatures on the computer screen. I describe three StarLogo projects created by high-school students. Based on my observations of these and other students, I analyze the nature of the centralized mindset, and I discuss how people, through engagement with new types of computational tools and activities, can begin to move beyond the centralized mindset.
