Social networking sites (SNS) shape political discourse by influencing which content gains
visibility, how users engage, and how political messages circulate. The introduction of
moderation tools, such as algorithmic filtering, labeling, or fact-checking, has triggered growing
debate about their legitimacy, effectiveness, and impact on political behavior and institutional
trust. These concerns have intensified following recent deregulatory shifts and the renewed
spread of harmful content. This interdisciplinary project investigates how SNS affect democratic
participation, political engagement, and polarization. It focuses on three key areas: how users
perceive algorithms and how these perceptions shape political attitudes, how harmful political
content is produced, circulated, and interpreted, and how people respond to different forms of
platform regulation. Using a mixed-methods approach, the project provides insight into the
implications of digital visibility, content dynamics, and governance, contributing to academic
debates and evidence-based policymaking.
