Disinformation and Misinformation Memes

Memes serve as more than just vehicles for online expression, demonstrating their power as weapons in the arsenal of misinformation and disinformation. Frequently dismissed as harmless jokes, memes have disproportionate power and are difficult to control or counter because they combine sincerity and satire. Memes should thus be taken seriously, especially as they enable harmful content to circulate under the guise of humour. It’s important to distinguish between disinformation, which represents the deliberate dissemination of incorrect information, and misinformation, which refers to the unintentional circulation of inaccurate information. In the context of disinformation, memes act as “compact carriers of political messaging,” easily co-opted for ideological manipulation. This manipulation is compounded when content originating from trolls or bots is shared by ordinary users, extending its reach, and legitimacy as well as feeding into misinformation cycles. This blog post will explore how memes function as disinformation and misinformation tools, examine their effectiveness, present three case studies, and evaluate the challenges posed to fact-checking and digital literacy.

Why are memes so effective for disinformation and misinformation?

Memes are highly effective tools for spreading disinformation because they exploit both the architecture of social media and the vulnerabilities of human cognition. Disinformation campaigns are often driven by coordinated actors who deliberately craft memes to mislead and manipulate public opinion, in turn leading to misinformation. To effectively do so, these memes rely on emotional resonance, repetition, and rapid peer-to-peer sharing to embed falsehoods within public discourse. In addition, the format of memes is visually more engaging and easier to process than text, which becomes especially persuasive when users lack deep investment in the topic, offering quick, credible-feeling impressions that bypass critical scrutiny. Furthermore, memes often rely on familiar visuals, remixed with new ideas, often extreme, which shape their relatability and contribute to their viral spread. In consequence, within polarised digital “cocoons,” such content gains traction, as users are rarely exposed to counterpoints and may even reject factual corrections outright.

Case study 1:

One striking example of anti-vaccine disinformation comes from a familiar meme that uses visuals from Drake’s Hotline Bling Music video to falsely claim that COVID-19 vaccines would alter human DNA, while suggesting that the virus’s recovery rate made vaccination unnecessary. This meme trivialised complex scientific issues through humour and visual familiarity, framing vaccination as unnecessary and even dangerous. Similar disinformation tactics were observed in a study on TikTok, where 25 of 38 videos discouraging vaccination featured parodies or memes of adverse reactions, accumulating over 70% of total views in that category. These were not just jokes, but deliberate efforts to undermine trust in vaccines. Such memes often vilify governments, portray the unvaccinated as victims, and strategically circulate as part of “meme wars” aimed at manipulating public opinion. This blend of humour, distortion, and virality makes memes uniquely potent tools of disinformation, especially among younger audiences. Importantly, this form of visual disinformation has historical precedent in the 19th century, political cartoons during the smallpox immunisation campaign also evoked fear and ridicule about vaccines. Then as now, memes, whether printed or digital, serve as powerful tools for emotional persuasion and public doubt.

Case study 2:

A third case reveals how memes distort scientific legitimacy. A viral meme presented side‑by‑side images of Greta Thunberg and climatologist Judith Curry, claiming Thunberg received “24/7 media coverage” while Curry, who supposedly called climate change a “hoax”, was ignored. This implied a manipulative media double standard. In reality, Curry acknowledges human‑driven climate change, though she emphasises natural variability, and enjoys coverage in conservative outlets, contradicting the meme’s narrative. Experts argue that this false equivalence misleads the public into believing there’s a 50/50 scientific debate when consensus is overwhelming. This example reveals how memes can deceptively distort credentials and coverage to instill doubt about established science.

Why are memes hard to fact-check?

Memes present a unique challenge for fact-checking due to their layered, ambiguous, and constantly evolving nature. Marc Dupuis and Andrew Williams denote that memes are hard to fact-check because their simple image or text format means traditional verification methods, such as analysing the source or language patterns, may not be useful for determining legitimacy. Additionally, the perceived truth of a meme is often subjective, shaped by the viewer’s social group and visual interpretation. Memes frequently occupy a grey area between satire and disinformation, using irony, inside jokes, and “edgy” humour to blur intent and create plausible deniability. This ambiguity makes them difficult to definitively identify or moderate. Further complicating matters, memes are remixed anonymously and mutate rapidly, with each new iteration distancing itself from the original context. As a result, platforms and fact-checkers struggle not only to trace their origins but also to distinguish between cultural commentary and coordinated manipulation.

Ways forward

While memes have proven to be powerful tools for spreading disinformation, they may also hold the key to resisting it. Scholars such as Hye Jin Yoon and Yan Huang propose “fighting fire with fire” by using memes themselves, particularly humorous ones, to expose and subvert deceiving information. These counter-memes could provoke emotional responses like discomfort or scepticism, disrupting the casual spread of harmful content. Similarly, as shown through climate meme communities, creators are using humour and relatability not only to cope with eco-anxiety, but to humanise complex issues, foster shared emotional resilience, and encourage more inclusive forms of digital activism

Yet solutions also require a deeper understanding of user behaviour. As established earlier, ordinary users play a central role in amplifying disinformation, oftentimes unknowingly. As such, distinguishing between intentional and unintentional sharing of false information is critical for designing effective interventions. Educating users, while important, must be paired with ethical journalism, and clear contextualization of visual symbols and narratives. Consequently, by studying how memes are shared, shaped by audience, anonymity, and platform norms, such as Dupuis and Williams’ survey, smarter, culturally aware responses can be developed that use the visual language of memes not to deceive, but to empower and inform.

But as meme culture evolves, a pressing question emerges: how do we prepare for a future where deep fakes and AI-generated memes further blur the line between truth and manipulation, making disinformation increasingly harder to detect? Given this persistent threat, such content is something policymakers and political campaigns must monitor closely.
