• Resumen

  • This scoping review investigates the complex landscape of fake news research, focusing on its link with attitudinal polarization and identifying key themes in the literature. Our objectives included mapping the main themes in fake news literature, analyzing how these themes connect, examining how polarization is conceptualized across studies, and how fake news and attitudinal polarization are related. Through an extensive theme analysis of fake news research sourced from SCOPUS and Web of Science databases, we identified four major thematic areas: (1) the influence of technologies and platforms on fake news, (2) user engagement and behavioral responses to fake news, (3) fake news characteristics and their social consequences, and (4) strategies for fake news detection and countermeasures. In-depth analysis of 20 selected peer-reviewed papers revealed significant inconsistencies in the operationalization of both fake news and polarization and in the definitions of polarization. Regarding evidence on fake news’ influence on polarization, mixed results are found, with some studies indicating attitude reinforcement, while others find negligible effects. This scoping review highlights the need for standardized methodologies to clarify fake news’ role in attitudinal polarization and societal division, calling for a unified framework in fake news and polarization research to advance understanding of fake news’ societal impact.
