"Affective polarization has been a persistent feature of Afghanistan’s society and politics in the past decades. However, with the instantaneous collapse of the republic’s government and the return of the Taliban, the country has witnessed heightened affective polarization along ethnic and ideological lines. Stemming from deep-rooted historical grievances, aggregated conflicts, and over a century of failed struggles for statebuilding and nation-building in Afghanistan, the surge in affective polarization is intricately linked with the elite’s behaviour and social media use. Outbidding strategies by elites result in more extreme positions. Coupled with the dissemination of hate and harmful messages, and divisive online content, this attracts wider attention and social support against a background of dwindling inter-group trust, state failure, and uncertainty over the political prospects. This article attempts to conceptualize the complex causal relations of affective polarization, elite behaviour, and social media platforms in Afghanistan’s fragmented social and political landscape."
