Measuring the Structural Impact of Misinformation on Network Polarization: An E-I Index and Random Walk Controversy Analysis

Öz

This study investigates the structural relationship between misinformation and network polarization in the context of online health discourse on social media. Using a comparative network analysis approach, four distinct discourse communities represented by hashtags: #pandemic (official terminology), #infodemic, #plandemic, and #scamdemic (misinformation narratives) is examined. These hashtags were selected because they represent distinct information frames ranging from official public-health terminology to misinformation. Both structural network metrics (average degree, path length, clustering coefficient, density, modularity) and polarization-specific measures (E-I Index, Random Walk Controversy/RWC) is employed to quantify differences in network topology and segregation patterns. Findings reveal a systematic gradient in structural polarization aligned with the type of narrative. The network using officially recognized terminology (#pandemic) exhibits low polarization (E-I = -0.483, RWC = 0.042), indicating minimal barriers to cross-group information flow and a relatively integrated structure. In contrast, misinformation-associated networks show significantly higher polarization, characterized by strongly negative E-I Index values (ranging from -0.692 to -0.821), high RWC scores (ranging from 0.723 to 0.846). In particularly, #scamdemic demonstrates extreme segregation (E-I = -0.821, RWC = 0.846), characteristic of echo chambers with limited cross-community exposure. These networks also display longer path lengths, higher modularity, and lower clustering coefficients, indicating fragmented, sparse connectivity patterns. The analysis establishes that misinformation ecosystems are structurally embedded within more polarized and segregated network architectures. These polarized structures function as echo chambers that reinforce in-group consensus while limiting exposure to corrective information. The relationship between misinformation narratives and structural polarization metrics suggests that network topology itself can serve as an early indicator of problematic information environments. These findings highlight the need for early detection tools integrating network-based polarization indicators into misinformation monitoring systems.
