Social media, disinformation, and democracy: how different types of social media usage affect democracy cross-nationally

Much speculation exists regarding how social media impacts the health of democracies. However, minimal scholarly research empirically examines the effect social media has on democracy across multiple states and regions. Thus, this article analyses the effect social media and disinformation transmitted over social media have on democracy. The findings from a cross-national, time-series analysis of 158 states from 2000–2019 indicate that different types of social media usage have varying effects on democracy. General social media consumption, the presence of diverse political viewpoints on social media, and the use of social media in political campaigns bolster democracy. However, social media disinformation, online political polarization, and the use of social media to organize offline violence reduce overall levels of democracy. In addition, a mediation analysis is conducted to identify the precise linkages between social media disinformation and democracy and indicates that government and political party disinformation impact democracy by weakening key democratic norms.
