Advancing the study of political misinformation across countries and platforms—introduction to the special issue

Summary

This editorial introduces a special issue dedicated to broadening political misinformation research beyond its WEIRD (Western, Educated, Industrialized, Rich, Democratic) bias. Humprecht and colleagues argue that political misinformation is a global democratic problem whose dynamics vary substantially across political systems, cultures, and platform ecologies, and that the field’s empirical base is too narrow to support generalizations. They frame the collected articles as a coordinated push toward comparative, cross-platform, and interdisciplinary inquiry, positioning the issue as both a corrective to existing literature and an agenda-setting intervention for future scholarship.

Key Contributions

• Articulates a critique of the WEIRD-centric concentration of misinformation research and the limits this places on generalizability.
• Advances comparative and cross-platform designs as the methodological standard for the next phase of misinformation scholarship.
• Provides an interdisciplinary framing that connects communication, political science, and platform studies around democratic resilience.
• Curates a body of empirical work that collectively illustrates context-dependent variation in misinformation phenomena.

Methods

This is an editorial introduction rather than an empirical study. The authors synthesize and contextualize the special issue’s articles, drawing out their shared comparative, cross-national, and cross-platform commitments and situating them within broader debates about de-Westernizing communication research.

Findings

• Misinformation dynamics — including spread, perception, and countermeasures — vary meaningfully across political, cultural, and technological settings.
• The current literature’s geographic concentration limits theoretical claims about how misinformation operates globally.
• Comparative and platform-spanning designs reveal phenomena obscured by single-country, single-platform studies.

Connections

This editorial frames the comparative agenda realized by cross-national contributions in the issue such as Humprecht-style resilience work extended in Mahl2026-hc, Cazzamatta2026-lo, and Hameleers2026-mc, as well as platform-comparative pieces like Rossini2026-jn and Dierickx2026-tw. It also sets the stage for the issue’s Global South and non-WEIRD investigations including Rodarte2026-dk, Shi2026-ko, Yoo2026-ev, and Choi2026-bz, complementing methodological and intervention-focused contributions such as van-der-Linden2026-jt and Spampatti2026-kx.
