Social Networks as Open Sources An Analysis of „Echo Chambers”

Abstract

This article examines the role of open-source intelligence (OSINT) and, more specifically, social media intelligence (SOCMINT) in understanding emerging social dynamics, focusing on the extremist narratives circulating on the Gab social media platform. As a poorly moderated and ideologically homogeneous environment, Gab functions as an echo chamber in which far-right and white supremacist ideas are generated, amplified, and normalized. Using a passive netnographic methodology, the study analyzes content posted between March and May 2024, identifying patterns of radicalization, hostile narratives, and identity-building processes within two dominant ideological themes: far-right nationalism and white supremacy. The findings demonstrate how social media platforms, whether mainstream or obscure, constitute valuable open sources for identifying early indicators of societal tensions, discursive polarization, and potential offline mobilization. By highlighting how echo chambers shape user perceptions and reinforce extremist worldviews, the article underscores the strategic value of OSINT/SOCMINT for policymakers and security institutions. Ultimately, the study shows that systematic monitoring of online ecosystems is essential for anticipating emerging risks and supporting preventive responses within the broader national security framework.
