Social Media’s Impact on Politics: A Brazilian Case Study
The pervasive influence of social media on politics is undeniable. The constant accessibility of platforms through mobile devices, coupled with established research on the causal impact of earlier media technologies like television and radio, underscores the transformative power of these digital tools. However, social media’s distinct characteristics set it apart from its predecessors, potentially leading to unique political consequences. Brazil, a nation at the forefront of social media adoption, provides a compelling case study for examining this impact. From the early days of Orkut to the present-day legal wrangling between the Brazilian Supreme Court and X (formerly Twitter), Brazilian politics has increasingly played out online over the past decade and a half, foreshadowing global trends and offering valuable lessons for policy considerations.
Traditional media, such as television, radio, and newspapers, primarily served as information access points. While politicians utilized these mediums to convey messages, they were inherently limited by the scarcity of outlets and the associated premium on space. Consequently, the impact of these media on politics manifested through accountability and propaganda. Empirical evidence demonstrates that media technologies generally enhanced accountability by providing information on politicians’ actions, unless displaced by a more effective information-dissemination technology. Furthermore, while traditional media could be potent tools for mobilization and persuasion, their effectiveness as propaganda relied on controlling content, which was often costly and accessible to only a few actors. Competition within media markets, therefore, played a crucial role in promoting accountability and preventing political capture.
Social media drastically alters this dynamic. Firstly, it dramatically lowers the barriers to entry for content creation and dissemination. Unlike traditional media, where broadcasting capabilities were restricted, social media empowers virtually everyone to produce and share content. Secondly, social media’s two-way communication feature revolutionizes interaction. The ability to directly connect with others, coordinate actions, and share views on these platforms is unparalleled in human history. These distinct characteristics initially fostered the belief that social media would herald a new era of democratic empowerment, exemplified by the optimism surrounding the 2011 Arab Spring.
However, the initial euphoria surrounding social media’s potential for democratic enhancement has faded. The very features that initially seemed to empower citizens – low barriers to entry and two-way communication – were also readily exploited by political actors. Politicians rapidly recognized social media’s potential to directly engage voters, reinforce support, and achieve political objectives without necessarily increasing responsiveness to the electorate. Even authoritarian leaders discovered that the abundance of information on social media, while making censorship harder and protests more likely, also offered new opportunities for demobilization through information overload – a strategy described as "flooding the zone with shit." The shift from traditional media gatekeepers to an environment of information saturation created fertile ground for political manipulation.
The evolution of social media algorithms further amplified these trends. Initially, platforms were relatively unsophisticated in content organization. However, the realization that engagement drove monetization led to the development of finely tuned algorithms and addictive features that profoundly impacted the political landscape. These algorithms catalyzed the formation of "homophilic" networks – communities of like-minded individuals. As engagement proved stronger for extreme content, algorithms inadvertently fueled polarization, particularly the negative kind rooted in shared animosity towards out-groups. Consequently, social media’s impact has been complex and multi-faceted, linking to increased political information and mobilization, but also escalating distrust in institutions, polarization, and support for populist politicians.
Brazil offers a vivid illustration of these dynamics. The unforeseen protests of June 2013 showcased social media’s mobilizing power, particularly Facebook’s role in facilitating collective action. By 2014, the strategic exploitation of social media for electoral purposes became evident, with untraceable rumors circulating on Facebook, highlighting the potential for disinformation. The 2018 presidential election, dubbed the "WhatsApp election", solidified the transformative influence of social media, propelling Jair Bolsonaro to an unexpected victory through strategic disinformation and the amplification of existing polarization. The trend continued in the "TikTok" election of 2022. While traditional factors like incumbency and conventional media retain some influence, particularly in local elections, the underlying shift towards social media dominance persists. The rapid rise of figures like Pablo Marçal, although potentially ephemeral, underscores the declining power of traditional gatekeepers in the age of social media.
Brazil’s prominent role in grappling with social media’s political implications is reflected in its policy initiatives. The ongoing conflict between X (formerly Twitter) and the Brazilian Supreme Court epitomizes the challenges of combating misinformation. While aggressive measures against misinformation may have been necessary during periods of democratic fragility, such approaches raise concerns about freedom of speech and long-term sustainability. Given the fundamental technological nature of social media’s challenges, it seems unlikely that judicial interventions alone can effectively stem the tide. Furthermore, the global reach of social media exacerbates these difficulties. Short of establishing a separate online ecosystem like China’s, isolating a nation from specific content comes at a significant cost. In the absence of international policy coordination, the current trajectory of increased polarization, unpredictability, and resulting instability seems likely to persist. We must prepare for an extended and challenging navigation through the "flooded zone" of information overload.
