For Whom The Tale’S Told: Multilevel Perspective On Narrative And Identity In Information Ecosystems, Jihye Song Jan 2026

For Whom The Tale’S Told: Multilevel Perspective On Narrative And Identity In Information Ecosystems, Jihye Song

Graduate Studies Theses and Dissertations 2026

In contemporary online information environments, narratives do not merely convey facts. They organize meaning, signal identity, and guide collective sensemaking. During periods of crisis and uncertainty, these processes become especially salient, as individuals and communities turn to social media to interpret unfolding events. At the same time, these environments are shaped by complex sociotechnical dynamics, including platform affordances, algorithmic amplification, elite influence, and grassroots participation. These dynamics form ecosystems in which narratives and identities are constructed, contested, and stabilized. Drawing on theory and empirical analyses of COVID-19 discourse on Twitter, this work develops and applies a multilevel framework to explain …
