Global Misinformation and Electoral Manipulation: Dangers, Case Studies, and Responses

A large crowd gathers with a variety of signs during a protest, including one featuring a cartoon character with the message in German, "Nein Patrick, die AfD ist keine Alternative" (No Patrick, the AfD is not an alternative).

We live in a time when falsehood can move across borders faster than truth, and that fact has become one of the central political dangers of the twenty first century. The World Economic Forum warned in its 2025 Global Risks Report that misinformation and disinformation remain among the top short term global risks because they erode trust, deepen division, and undermine governance. The United Nations has made a similar point, warning that digital technologies now allow false and misleading content to spread at an “unprecedented volume, velocity and virality.” 

What makes this threat so serious is not simply that people lie. Political lying is old. What is new is the scale, speed, and intimacy of modern manipulation. Research from MIT found that false news spreads farther, faster, deeper, and more broadly on Twitter than true news, and that humans, not bots alone, are primarily responsible for that spread. The same research found false stories were 70 percent more likely to be retweeted than true ones. Another study from Yale found that even a single prior exposure to fake news can increase the likelihood that people later judge it to be accurate. In other words, repetition itself can make lies feel true. 

That becomes especially dangerous when political leaders or movements learn to use misinformation not just to persuade, but to manufacture legitimacy. In the Philippines, scholars studying the 2016 presidential election described it as the country’s first “social media election.” Their analysis of twenty million activities and nearly forty thousand sampled comments found that Rodrigo Duterte’s online profile was the most engaged among the leading candidates. At the same time, the researchers noted inconsistencies that raised the prospect that part of that prominence had been fabricated by paid trolls and fake accounts. Even where genuine support existed, the study showed how hard it had become to separate real enthusiasm from manipulated visibility. 

Brazil offers another warning. A 2023 study in Social Media + Society found that WhatsApp “played a key role” in the election of Jair Bolsonaro in 2018 and later remained central to organized disinformation efforts tied to government aligned propaganda. The authors traced how false and misleading narratives moved from campaign tactics into a broader political communications machine. That matters because it shows misinformation is not always a temporary election trick. Once normalized, it can become part of governance itself, shaping public opinion long after ballots are counted. 

Even when the exact effect of disinformation on vote totals is difficult to prove, the institutional damage is undeniable. In the United States, the declassified intelligence assessment released through the Senate Intelligence Committee concluded that Russian activities targeted the 2016 election, though the intelligence community did not assess whether those activities changed the final outcome. That distinction is important. A disinformation campaign does not need to be proven decisive to be dangerous. It can still poison public trust, weaken confidence in democratic procedures, and make citizens doubt whether any source of information is reliable. 

The harm also extends beyond elections. The World Health Organization defines an “infodemic” as an overabundance of information, including false or misleading information, that spreads during a crisis and makes it harder for people to find trustworthy guidance. In politics, the same mechanism can produce social paralysis. Citizens stop knowing what to believe. Journalists are branded enemies. Experts are dismissed as partisan. Facts become optional, and emotional loyalty becomes more important than evidence. Once that happens, democracy is no longer an informed public choice. It becomes a competition over who can manipulate fear, anger, and identity most effectively. 

That is why misinformation is not merely a communications problem. It is a democratic one. When leaders use falsehood strategically, they do more than win attention. They train the public to distrust independent institutions and to treat reality itself as negotiable. In that environment, elections may still take place, but the civic conditions that make elections meaningful begin to rot. People are not persuaded through open debate. They are nudged, saturated, and emotionally engineered.

The response cannot be censorship masquerading as virtue, but it also cannot be complacency. The United Nations Global Principles for Information Integrity call for a healthier information ecosystem grounded in public empowerment, independent and pluralistic media, transparency, and research. Those ideas point in the right direction. Democracies need stronger media literacy, more transparency from digital platforms, better support for serious journalism, and leaders who see truth as a public duty rather than a disposable campaign tool. If we fail to defend those norms, misinformation will not simply distort politics. It will slowly redefine what politics is.
