    Advancing the Study of Political Misinformation Across Countries and Platforms-Introduction to the Special Issue
    (SAGE PUBLICATIONS INC, 2025) Humprecht, Edda; Valenzuela Leighton, Sebastián Andrés; Esser, Frank; Tandoc, Edson
    The global spread of political misinformation poses serious challenges to democracies, eroding trust and distorting public discourse. However, research has largely focused on WEIRD countries-Western, Educated, Industrialized, Rich, and Democratic-limiting our understanding of how misinformation operates across diverse political, cultural, and technological contexts. This special issue addresses these gaps through comparative, cross-platform, and interdisciplinary perspectives. The articles explore how political and media systems shape misinformation, the role of individual resilience, and how platform-specific features-across social media, messaging apps, and traditional media-affect the spread of false information. Studies from non-WEIRD regions offer insights into distinct vulnerabilities, emphasizing the need for context-sensitive approaches. Together, these contributions advance our understanding of misinformation as a global challenge and offer guidance for strengthening democratic resilience in varied information environments.

    Political participation and technology: Continuities and discontinuities in the Southern Cone and Brazil
    (Taylor and Francis, 2024) Barbosa Dos Santos, Marcelo Luis; Valenzuela Leighton, Sebastián Andrés; CEDEUS (Chile)
    This chapter investigates the relationships between technology and political participation in Argentina, Brazil, Chile, and Uruguay-four neighboring countries in the southern part of the Americas. While Uruguay and Chile boast more digitized societies, Brazil and Argentina’s size and geopolitical influence create distinct technological landscapes. The adoption and cultural components of technological innovation are influenced by economic, political, and media systems, resulting in customized political outcomes. Digital technologies, such as mobile communication and social media, intervene in processes of political participation, polarization, social unrest, and other phenomena through algorithmic biases and trend detection mechanisms. Examining various forms of technologically mediated political participation, including computational propaganda, misinformation, digital activism, and digital surveillance, this chapter explores continuities and discontinuities that define the digital political ecosystems in these countries.

    Taming the digital information tide to promote equality
    (2019) Valenzuela Leighton, Sebastián Andrés; Rojas, Hernando
    Interactive technologies are changing the ways we learn facts, develop attitudes and participate in politics, with the ensuing risk of increasing pre-existing inequalities. Addressing this challenge is the duty of researchers, technology companies, governments and news organizations.
