The 2025 Chilean presidential election served as a stark case study in the weaponization of disinformation, as coordinated online campaigns targeted female candidates Evelyn Matthei and Jeanette Jara to marginalize them through entrenched gender stereotypes. Investigations revealed that anonymous accounts spread fabrications, such as false claims regarding Matthei’s health, while a broader analysis found that nearly half of all electoral misinformation originated directly from the candidates themselves. Although these tactics were purportedly linked to the Republican Party, leader José Antonio Kast denied involvement, leaving the true origins of the campaign shrouded in ambiguity as the race concluded with his victory.
This recurring pattern demonstrates how disinformation is increasingly utilized as an authoritarian tool to sabotage accountability and manipulate public perception. While debates often focus exclusively on the business models of social media platforms, experts argue that a systemic response is required to address how powerful actors exploit the digital landscape to disable democratic discourse. Because these campaigns often involve a complex web of private PR firms and anonymous state-affiliated actors, they are significantly harder to track and dismantle than traditional forms of media censorship or site-wide internet shutdowns.
Independent journalism has emerged as the frontline defense against these opaque manipulation networks, yet it remains under immense strain. While investigators were successful in exposing the deceptive coordination behind the Chilean campaign, the financial instability plaguing the news industry—coupled with frequent physical and digital harassment—creates a fragile environment for deep-dive reporting. Furthermore, the not-for-profit fact-checking sector is facing significant headwinds, as social media platforms reduce their support for third-party verification and reliance on short-term, unsteady grant funding makes long-term operations increasingly difficult to sustain.
To combat these challenges, policy innovation must shift toward robust regulatory frameworks that go beyond platform governance. New privacy laws, such as those recently adopted in Chile and the European Union, are becoming essential tools for restricting the unauthorized use of personal data, including the use of an individual’s likeness to create malicious AI-generated deepfakes. Similarly, stringent regulations on political advertising—such as those implemented by the Supreme Electoral Tribunal in Brazil—are necessary to bring transparency to AI-driven campaigns, particularly in regions like Chile where existing broadcast regulations fail to address the content of candidate media.
Protecting the integrity of democracy ultimately requires a foundation of institutional trust paired with a highly resilient public. The Chilean Electoral Service (Servel) serves as a successful model for this, utilizing independent monitoring and proactive public communication to debunk falsehoods before they can erode confidence in the electoral process. Strengthening this institutional pillar must be complemented by large-scale investments in digital and media literacy, ensuring that citizens across all demographics possess the critical thinking skills necessary to parse and resist the rapid virality of disinformation.
Successfully countering the weaponization of information requires governments to move away from ineffective, authoritarian-leaning policies, such as vague “fake news” laws that often serve only to silence legitimate criticism. Instead, states must adopt a comprehensive, human-rights-compliant strategy that integrates preventive legislation, support for independent media, and rigorous data protection. By fostering transparency and empowering the public through education, democratic societies can better navigate the digital age, ensuring that the architecture of their institutions remains resilient against those who seek to entrench power through deception.
