TL;DR

This paper models the Information Society as a complex system using statistical physics tools—specifically the Ising model for the Digital Divide and a generalized Lotka-Volterra model for internet Governance—demonstrating that targeted policies (modeled as external fields) can shift societal states toward greater inclusion and cooperation, even with scarce empirical data.

ABSTRACT

Considering electronic implications in the Information Society (IS) as a complex system, complexity science tools are used to describe the processes that are seen to be taking place. The sometimes troublesome relationship between the information and communication new technologies and e-society gives rise to different problems, some of them being unexpected. Probably, the Digital Divide (DD) and the Internet Governance (IG) are among the most conflictive ones of internationally based e-Affairs. Admitting that solutions should be found for these problems, certain international policies are required. In this context, data gathering and subsequent analysis, as well as the construction of adequate physical models are extremely important in order to imagine different future scenarios and suggest some subsequent control. In the main text, mathematical modelization helps for visualizing how policies could e.g. influence the individual and collective behavior in an empirical social agent system. In order to show how this purpose could be achieved, two approaches, (i) the Ising model and (ii) a generalized Lotka-Volterra model are used for DD and IG considerations respectively. It can be concluded that the social modelization of the e-Information Society as a complex system provides insights about how DD can be reduced and how the a large number of weak members of the IS could influence the outcomes of the IG.

Motivation & Objective

• To address the lack of reliable data in studying complex socio-technical systems like the Information Society.
• To analyze the Digital Divide (DD) and internet Governance (IG) as systemic challenges requiring policy intervention.
• To develop a modeling framework that simulates policy effects on agent behavior in the absence of comprehensive empirical data.
• To demonstrate how complex systems tools can forecast policy outcomes and guide inclusive, development-oriented strategies.
• To show that weak agents in the Information Society can collectively influence governance outcomes through coordinated behavior.

Proposed method

• Adopts the Huang version of the Ising model to represent individual agents in a social network, with states +1 (in) and -1 (out) reflecting inclusion in the Information Society.
• Introduces an external field (H) as a proxy for policy interventions, simulating how top-down measures can shift agent states.
• Uses a generalized Lotka-Volterra multiagent system to model competitive and cooperative dynamics among old and new agents in internet Governance.
• Simulates agent interactions on a 2D lattice with nearest-neighbor coupling, allowing for phase transitions and stable configurations.
• Applies time-series simulations to track the evolution of agent states (in/out) under different policy strengths (H = 1, H = 2).
• Varying cooperation rates among new agents (from 50% to 100%) to assess collective influence on system-wide outcomes.

Experimental results

Research questions

• RQ1 How can policy interventions be modeled in a complex social system with limited empirical data?
• RQ2 To what extent can the Ising model simulate the dynamics of the Digital Divide and the impact of inclusionary policies?
• RQ3 How do varying levels of cooperation among new agents affect the stability and outcome of internet Governance systems?
• RQ4 Can weak agents collectively influence governance outcomes in a complex system, even without dominant structural power?
• RQ5 What role does policy strength (modeled as an external field) play in shifting societal states toward inclusion and cooperation?

Key findings

• The Ising model successfully simulates the transition from a fragmented, unequal state (high Digital Divide) to a more inclusive state under policy intervention (external field H).
• With H = 1, the number of 'in' agents (included) increases over time, indicating policy effectiveness in reducing exclusion.
• At H = 2, the system reaches a stable, highly inclusive configuration, showing that stronger policies lead to faster and more complete integration.
• The Lotka-Volterra model reveals that when 100% of new agents cooperate, the system stabilizes into a cooperative regime, even when old agents remain competitive.
• The model shows that increasing cooperation among new agents reduces system instability and accelerates convergence to a stable, inclusive outcome.
• The simulations demonstrate that weak agents (newcomers) can collectively shift the system's equilibrium, suggesting a pathway for bottom-up influence in internet Governance.
