Digital Activism and Public Support in the Post-Truth Era: Systematic Review (2015–2025)

Digital activism has emerged as a prominent mode of political engagement in the post-truth era, where misinformation, emotionally charged discourse, and declining trust in institutions complicate democratic participation. This study examines how digital activism gain public support under such conditions by conducting a mixed-methods systematic review that combines bibliometric analysis with thematic synthesis. Drawing on 1,311 peer-reviewed articles published between 2015 and 2025, retrieved from the Scopus database, the analysis focuses on studies published in English that address both digital activism and public support. The data were examined through bibliometric visualization using VOSviewer and thematic coding to extract core qualitative insights. The findings reveal that digital activism is shaped by affective narratives, identity politics, and algorithmic governance. Emotional storytelling and credibility cues mediate how public support is cultivated, while the affordances of specific platforms influence modes of civic engagement. Notably, the concept of disconnective action has emerged, where activists intentionally withdraw from co-opted digital spaces as a form of resistance. Furthermore, the analysis highlights significant asymmetries between Global North and Global South contexts. While the former tends to emphasize issues of governance and ethics, the latter focuses on resilience and resistance within repressive regimes. These findings suggest that digital activism in the post-truth era is increasingly driven by emotional engagement and mediated by algorithmic infrastructures rather than factual consensus. This dynamic underscores the need for interdisciplinary approaches and globally inclusive perspectives to navigate the complexities of trust, visibility, and sustainability in digital political participation.
