Knowledge and Language

In today’s hyperconnected world, knowledge is more accessible than ever, but this accessibility comes with new challenges. With the rise of digital media, information flows constantly, reaching knowers around the world at incredible speed. But while this allows us to access a vast array of perspectives and insights, it also means we’re exposed to misinformation, disinformation, and fake news on an unprecedented scale. This raises a critical "problem of knowledge" in Theory of Knowledge (TOK): how do we, as knowers, distinguish reliable information from misleading or false content?

Misinformation, disinformation, and fake news each pose unique threats to our pursuit of knowledge. Misinformation is often shared unknowingly, spreading inaccuracies that can shape beliefs subtly and gradually. Disinformation, on the other hand, involves deliberate deception, typically to push political or ideological agendas. And then there’s fake news, fabricated stories made to look like legitimate reporting but designed to deceive, entertain, or provoke reactions. Together, these phenomena distort reality, affect public opinion, and can even lead to dangerous real-world consequences.

For IB students tackling their 2025 TOK Essay or even your initial TOK Exhibitions in Year 1, understanding these concepts is crucial. The TOK framework encourages us to question how we know what we know, and these issues challenge the very foundation of knowledge itself. How can we claim to know something if our sources are unreliable? How does bias influence our acceptance of certain information? By examining these questions through the lens of misinformation, disinformation, and fake news, you gain insights into how knowledge is constructed—and manipulated—in today’s world.

In this post, we’ll explore these three concepts in depth, using recent examples to illustrate their impact. Let’s start by delving into misinformation and how it subtly shapes our perceptions.

Misinformation

Misinformation is unintentional false information shared by people who often believe it to be true. It typically spreads on social media, where individuals unknowingly pass on inaccuracies about health, politics, and current events. This is especially relevant to TOK because it demonstrates how knowledge can be shaped—or misshaped—by well-meaning but uninformed individuals.

Health misinformation is a prime example. During the COVID-19 pandemic, misinformation about "miracle cures" and preventive measures spread rapidly. Claims that unproven vitamins, herbs, or specific diets could prevent infection became common across social media platforms. Many people shared these claims because they wanted to help, but without scientific backing, these recommendations often gave a false sense of security or led people to avoid legitimate health measures. Such health misinformation has a real-world impact, as it can lead to people making poor decisions that endanger themselves or others.

Another area where misinformation thrives is in the political sphere. For instance, during recent elections worldwide, social media was supposedly rife with posts and videos making unverified claims about candidates or policies. These posts are often amplified by confirmation bias, as people are more likely to share information that aligns with their beliefs. Even when misinformation is corrected, the initial false claims often stick in people’s minds, a phenomenon known as the "continued influence effect."

Recent examples also highlight the potential of seemingly harmless misinformation to lead to real-world consequences. In October 2024, for example, a company mistakenly promoted a non-existent Halloween parade in Dublin. Thousands of people showed up on O'Connell Street, expecting a parade of giant Halloween puppets that didn’t exist. While this error was not malicious, it demonstrated how quickly misinformation can spread, with real-life consequences. Events like these show that misinformation doesn't always come with bad intentions but can still affect people’s actions and expectations.

Disinformation

Unlike misinformation, disinformation is intentionally false information designed to deceive. It’s a deliberate attempt to manipulate public opinion, usually for political or ideological purposes. Disinformation campaigns are especially relevant in TOK as they underscore the ethical dimensions of knowledge and how intentional manipulation of facts can distort public understanding.

A powerful example of disinformation occurred in the lead-up to India’s 2019 general election. Social media platforms, particularly WhatsApp, became flooded with false information targeting political opponents and religious minorities. One viral video, created by editing existing footage, purportedly showed the Indian President making a controversial statement. Although fact-checkers debunked the video within hours, millions had already viewed and shared it. This illustrates the speed and scale at which disinformation can spread, especially on platforms where users don’t verify the authenticity of what they see before sharing it.

Disinformation campaigns also take advantage of “echo chambers” on social media, where people are exposed primarily to content that reinforces their own beliefs. This selective exposure can lead individuals to accept disinformation uncritically, as it aligns with their existing worldviews. In Myanmar, for example, disinformation was used to stir up hostility against the Rohingya population. The Myanmar military reportedly created fake accounts on Facebook to share incendiary content, accusing the Rohingya of fabricated crimes. This disinformation campaign incited hatred, leading to violent acts and widespread persecution.

These examples show the dark side of knowledge manipulation. Disinformation not only influences opinions but can fuel division and incite real-world violence. In the context of TOK, disinformation prompts us to ask challenging ethical questions about the responsibilities of knowers and the role of bias in our acceptance of information.

Fake News

Fake news is a fabricated story made to look like legitimate news, often to attract clicks, drive revenue, or push an agenda. Unlike misinformation, which may be shared innocently, fake news is often crafted to provoke a strong reaction or shape public perception. For TOK students, fake news is a crucial area to explore because it highlights the blurred line between truth and fiction in modern media and raises questions about what constitutes "legitimate knowledge."

Historically, fake news has been around for centuries. One of the earliest cases dates back to 1835, when the New York Sun published a series of articles about life on the moon. The story was entirely false but drew significant attention before people realized it was a hoax. Today, however, fake news is much harder to contain, as social media allows stories to reach global audiences in minutes.

In 2017, after the Las Vegas mass shooting, a conspiracy theory quickly circulated online suggesting that the event was staged as part of a coordinated plot involving various groups. This fake news story gained enough traction to appear at the top of search results, demonstrating how quickly fabricated stories can dominate the online narrative. Even after these theories were debunked, the damage was done, as many people continued to believe in the conspiracy. This is a powerful example of the "anchoring effect," where initial impressions are hard to change, even when the facts are corrected.

More recently, fake news has influenced political landscapes. During the 2020 U.S. presidential election, false stories about voter fraud were shared widely, fueling public distrust. This disinformation led to protests and, ultimately, the storming of the U.S. Capitol in January 2021. In this way, fake news can undermine democratic institutions and disrupt social order, highlighting the importance of media literacy and critical thinking in today's information-rich world.

Understanding misinformation, disinformation, and fake news isn't just about spotting falsehoods—it’s about evaluating how we know what we know and the ethical responsibilities that come with sharing knowledge. As you work on your TOK essay or exhibition, think about the impact of these issues on our understanding of truth and knowledge.
