Identical Platform, Divergent Publics: Sweden and Finland During the 2022 NATO Crisis

Policy &Internet, Volume 18, Issue 3, September 2026.
ABSTRACT Digital platforms are often theorized as universal drivers of political polarization, yet empirical patterns remain inconsistent across countries. Leveraging the natural‐experiment logic of Sweden's and Finland's simultaneous 2022 NATO applications and the NATO–Turkey diplomatic crisis, this study examines how national political cultures ...
