The 21st century has witnessed an unprecedented transformation in how narratives are constructed, disseminated, and weaponized. This lecture examines the evolving dynamics of propaganda, political communication, and digital disinformation, focusing on the dual role of social media platforms and artificial intelligence (AI) in reshaping the global information ecosystem. Beginning with a historical overview of propaganda—from 20th-century state-controlled media to today’s decentralized digital networks—the discussion highlights how technological advancements have amplified the speed, scale, and sophistication of narrative manipulation. Central to the analysis is the exploitation of social media by governments and political actors to spread partisan narratives, including AI-generated content such as deepfakes, synthetic media, and algorithmically optimized messaging. Case studies illustrate how these tools are deployed to influence policymakers, polarize societies, and undermine democratic processes (e.g., election interference campaigns, viral disinformation during crises). The lecture also addresses regulatory and legislative responses to these challenges, contrasting national approaches with EU-wide initiatives such as the Digital Services Act (DSA) and the AI Act. By evaluating policies aimed at platform accountability, transparency in political advertising, and ethical AI governance, the talk critically assesses the balance between safeguarding free expression and curbing digital harms. Ultimately, this lecture underscores the urgent need for multidisciplinary strategies—combining technology literacy, robust policymaking, and international cooperation—to navigate the “post-truth” era. Safeguarding fundamental rights, including freedom of thought, expression, and access to information, must remain central to these efforts, while guarding against undue political censorship or authoritarian overreach. By fostering frameworks that balance democratic accountability, ethical innovation, and digital resilience, societies can mitigate manipulative practices while preserving the open exchange of ideas essential to democratic governance.
