How Disinformation Spreads and Why It Works

Disinformation thrives in the digital ecosystem not just because falsehoods exist but because the platforms we use are designed to promote them.

Unlike traditional journalism, where editorial oversight ensures factual accuracy, social media prioritizes engagement, meaning that the most sensational, emotionally charged content gains the widest reach.

This system creates a perfect breeding ground for misleading narratives, conspiracy theories, and outright fabrications.

The Algorithmic Amplification of Falsehoods

One of the most troubling findings from Digital Democracy, Social Media, and Disinformation is that disinformation spreads faster, wider, and deeper than factual news (Iosifidis & Nicoli, 2021, p. 43).

The study echoes research from the Massachusetts Institute of Technology (MIT), which found that false information on Twitter is 70% more likely to be retweeted than the truth.

This phenomenon is not due to human error alone—it is built into the mechanics of social media. Platforms like Facebook and YouTube use recommendation algorithms that prioritize content that keeps users engaged, even if it is misleading or harmful.

For example, during the COVID-19 pandemic, misinformation about vaccines and treatments spread at an alarming rate.

The study notes that content promoting unproven treatments, conspiracy theories, and anti-science rhetoric gained millions of views before fact-checkers could intervene (Iosifidis & Nicoli, 2021, p. 85).

The reason? Outrage and fear generate higher engagement, which platforms reward with greater visibility.

Emotional Triggers: How Disinformation Bypasses Critical Thinking

Disinformation does not spread merely because of technological factors—it also exploits psychological vulnerabilities.

Studies show that people are more likely to believe and share content that triggers strong emotions like fear, anger, or validation of existing beliefs. This is why misleading stories often use exaggerated headlines, divisive rhetoric, or shocking imagery.

Iosifidis and Nicoli’s research highlights how misinformation campaigns during Brexit and the 2016 U.S. presidential election were strategically designed to inflame tensions and deepen ideological divides (2021, p. 85).

False stories about immigration, voter fraud, and government corruption were not just random viral posts—they were carefully crafted messages aimed at specific audiences, exploiting their existing fears and biases.

One key takeaway from the study is that disinformation often feels true to those predisposed to believe it.

Confirmation bias—the tendency to interpret information in a way that confirms pre-existing beliefs—plays a major role in why people fall for false narratives.

This means that simply presenting factual corrections is not always enough to change minds.

The Role of Bots, Trolls, and Coordinated Disinformation Campaigns

Not all disinformation spreads organically. Some of the most damaging false narratives are driven by coordinated efforts involving bots, troll farms, and paid influencers.

The study provides evidence that during key political events, automated accounts were responsible for amplifying misleading content at a scale that no human-driven effort could match (Iosifidis & Nicoli, 2021, p. 101).

For example, during the 2020 U.S. elections, researchers found that thousands of bot accounts were used to spread claims of voter fraud, creating an illusion of widespread distrust in the election process.

These bots interacted with real users, making it difficult to distinguish between authentic concerns and manufactured outrage.

Similarly, Russian-backed troll farms have been documented as playing a role in polarizing Western societies by pushing conflicting narratives on both sides of divisive issues.

Who Benefits from Disinformation?

Disinformation is not just an unfortunate side effect of the internet—it is a lucrative and powerful tool that benefits specific groups.

Understanding who gains from the spread of false narratives helps us recognize when we are being manipulated and why.

The study highlights three main beneficiaries: foreign actors, domestic political campaigns, and tech corporations.

Foreign Actors: Disinformation as a Geopolitical Weapon

One of the most significant threats outlined in Digital Democracy, Social Media, and Disinformation is how state-sponsored disinformation is used as a tool of geopolitical influence.

The Russian government, in particular, has been a key player in weaponizing social media to destabilize democracies, manipulate public opinion, and sow discord within Western societies (Iosifidis & Nicoli, 2021, p. 101).

Moscow’s disinformation strategy follows a clear pattern:

  • Amplifying divisive issues – Russian-backed disinformation often promotes both sides of contentious topics (such as racial tensions in the U.S. or Brexit in the UK) to exacerbate divisions.
  • Undermining trust in institutions – False narratives about election fraud, media bias, and government corruption are designed to weaken faith in democratic processes.
  • Disguising propaganda as independent news – State-controlled media outlets like RT and Sputnik produce misleading stories that get picked up and spread by unwitting users and even mainstream news sources.

The study warns that as long as foreign powers see digital disinformation as an effective and low-cost strategy, they will continue using it to shape international politics.

Domestic Political Campaigns: Misleading the Masses for Votes

It is not just foreign adversaries that exploit disinformation—many political parties and leaders within democratic nations use misleading narratives to influence elections, discredit opponents, and mobilize their bases.

The study documents numerous instances where social media was flooded with false claims in the lead-up to elections (Iosifidis & Nicoli, 2021, p. 61).

Common tactics include:

  • Astroturfing campaigns – Creating fake grassroots movements online to make fringe opinions appear more widespread than they are.
  • Deepfake videos and doctored images – Visual manipulation that distorts reality to attack political rivals or spread fear.
  • Selective misinformation – Using out-of-context statistics or misleading headlines to push an agenda while maintaining a veneer of credibility.

In many cases, disinformation is deliberately crafted to appeal to emotions rather than reason, making it harder for fact-checking to counteract its effects.

This highlights the need for voters to critically evaluate political content before sharing or acting on it.

Tech Corporations: Profiting from Polarization

While foreign governments and politicians weaponize disinformation for power, social media companies profit from its spread.

The study found that misinformation spreads six times faster than factual news on platforms like Twitter (Iosifidis & Nicoli, 2021, p. 43), largely because emotionally charged content generates higher engagement—and engagement is what keeps users scrolling and clicking.

Social media algorithms are designed to maximize attention, not truth.

The more time users spend on a platform, the more ads they see, driving up revenue for companies like Facebook, YouTube, and Twitter.

This creates a perverse incentive structure where:

  • Sensational content is rewarded – Even falsehoods that violate policies often go viral before platforms take action.
  • Fact-checking struggles to keep up – By the time a post is debunked, it has often already reached millions.
  • Attempts at moderation are inconsistent – While platforms remove some false content, they hesitate to act aggressively against disinformation sources that drive major traffic.

The study argues that unless tech companies are held accountable, they will continue to prioritize profits over public interest, allowing disinformation to flourish unchecked.

What We Can Learn: Practical Takeaways for Everyday Users

While large-scale policy solutions are essential in the fight against digital disinformation, the responsibility doesn’t rest solely on governments, regulators, or tech companies.

Individuals—everyday social media users—play a crucial role in either amplifying or combating the spread of false information.

The study provides valuable insights into how misinformation operates and, more importantly, how we can protect ourselves from being manipulated by it.

Pause Before Sharing: The Power of Deliberate Thinking

Disinformation spreads in large part because people share content impulsively.

The more emotionally charged a post is, the more likely it is to be reshared without verification.

The study notes that false stories often trigger outrage, fear, or strong personal validation, encouraging users to spread them instinctively (Iosifidis & Nicoli, 2021, p. 85).

What to do: Before hitting “share” on an article, meme, or video, take a few seconds to ask:

  • Is this from a credible source?
  • Could this be taken out of context?
  • Is it playing on my emotions?

Simply pausing before engaging can significantly slow the spread of misinformation.

Diversify Your Information Diet: Breaking Free from Algorithmic Bubbles

One of the key takeaways from the study is that social media platforms create echo chambers—environments where users are repeatedly exposed to the same types of content, reinforcing preexisting beliefs while filtering out dissenting views (Iosifidis & Nicoli, 2021, p. 61).

What to do:

  • Follow credible news organizations across the political spectrum.
  • Use independent fact-checking websites like Snopes or Reuters Fact Check.
  • Read from multiple sources before forming an opinion on an issue.

By broadening the range of information we consume, we can challenge biases and become more resistant to propaganda.

Recognize Emotional Manipulation: When Misinformation ‘Feels’ True

Misinformation is often designed to provoke strong emotional responses, making it more likely that people will believe and share it without scrutiny.

The study cites research showing that people are more susceptible to misinformation when they feel threatened, angry, or deeply validated (Iosifidis & Nicoli, 2021, p. 85).

What to do:

  • If a headline makes you angry or afraid, be extra skeptical.
  • Look at the language—does it use extreme words like “shocking,” “outrageous,” or “exposed”?
  • Seek out neutral sources to confirm the story before reacting.

Recognizing emotional manipulation helps us avoid being baited into spreading false narratives.

Look for Signs of Coordination: Identifying Bots and Fake Accounts

The study highlights that during major political events, bot networks and coordinated campaigns have been used to amplify disinformation on a massive scale.

In some cases, thousands of accounts simultaneously push the same misleading content to make it appear more credible and widely accepted (Iosifidis & Nicoli, 2021, p. 101).

What to do:

  • Check the source—does the account have a history of legitimate posts, or was it created recently?
  • Look for identical phrasing in multiple posts—this is a sign of automated amplification.
  • If a post is spreading rapidly but lacks reputable sources, be wary.

Being aware of these tactics makes us less susceptible to manipulated trends.

Engage in Constructive Conversations: Changing Minds with the Right Approach

One of the most frustrating aspects of online misinformation is seeing friends or family members share false or misleading content.

The instinct may be to call them out directly, but research suggests that aggressive corrections often cause people to double down on their beliefs rather than reconsider them (Iosifidis & Nicoli, 2021, p. 85).

What to do:

  • Instead of confronting someone with “You’re wrong,” ask, “Where did you hear that?”
  • Share a verified source that presents the correct information without attacking the person’s viewpoint.
  • If the conversation becomes hostile, disengage rather than escalate.

Studies suggest that when approached with curiosity rather than confrontation, people are more open to reconsidering false beliefs.

Why Self-Regulation by Tech Companies Has Failed

As digital disinformation has become a growing threat to democracy, social media companies have been pressured to address the problem.

In response, platforms like Facebook, Twitter, and YouTube have introduced measures such as content moderation, fact-checking partnerships, and algorithm adjustments.

However, as Digital Democracy, Social Media, and Disinformation makes clear, these efforts have largely failed to curb the spread of false narratives.

The core issue is that self-regulation conflicts with the economic incentives that drive these platforms (Iosifidis & Nicoli, 2021, p. 65).

The Engagement-First Business Model

At the heart of the problem is the way social media companies make money. Platforms rely on advertising revenue, which is maximized by keeping users engaged for as long as possible.

Unfortunately, research—including findings from the study—has shown that misinformation, sensationalism, and emotionally charged content drive higher engagement than factual reporting (Iosifidis & Nicoli, 2021, p. 43).

This creates a dilemma: any serious effort to reduce disinformation would also reduce profits.

Rather than addressing this core issue, social media companies have instead implemented superficial changes that appear proactive but fail to tackle the structural problem.

Inconsistent and Reactive Content Moderation

One of the main strategies social media platforms use to fight disinformation is removing false or misleading content.

However, the study highlights several flaws in this approach:

  • Content moderation is often slow and ineffective. By the time fact-checkers flag false content, it has often already gone viral. Research cited in the study found that fact-checking efforts typically occur long after misinformation has spread widely (Iosifidis & Nicoli, 2021, p. 85).
  • Policies are applied inconsistently. Some high-profile accounts and influential figures are given more leniency in spreading falsehoods, either because they generate high engagement or because platforms fear backlash over censorship accusations.
  • Misinformation often reappears in new forms. Even when false content is removed, it is frequently reposted with slight modifications, making it difficult to track and eliminate completely.

Fact-Checking Can’t Keep Up

Many platforms have partnered with independent fact-checkers to flag misleading content, but this approach faces significant limitations:

  • Fact-checking is slow, but misinformation spreads fast. The study notes that false stories travel at an accelerated pace compared to their corrections, making debunking efforts largely reactive (Iosifidis & Nicoli, 2021, p. 61).
  • People often distrust fact-checkers. Research shows that when misinformation is labeled as false, users who already believe it may see the correction as part of a biased agenda, leading them to double down on their original beliefs.
  • Fact-checking only reaches a fraction of users. Even when misinformation is flagged, many users may never see the correction—especially if the false information was initially spread widely.

The Limits of Algorithmic Fixes

Some platforms have attempted to use algorithmic adjustments to reduce the visibility of disinformation.

These efforts include:

  • Deprioritizing content flagged as misleading so that it reaches fewer people.
  • Detecting coordinated inauthentic behavior to remove bot networks.
  • Promoting credible sources over dubious ones.

While these steps sound promising, the study argues that they are ultimately inadequate for two reasons:

  • Bad actors continuously adapt. Disinformation campaigns evolve rapidly, finding new ways to evade detection and exploit loopholes in content moderation systems (Iosifidis & Nicoli, 2021, p. 99).
  • Platforms still prioritize engagement. Even when disinformation is deprioritized, the underlying incentive remains: content that sparks outrage and division generates more clicks and revenue.

What We Can Learn

The failure of self-regulation means that tech companies cannot be relied upon to fix the problem on their own.

As users, we need to:

  • Recognize that viral content is often designed to manipulate emotions and engagement.
  • Be skeptical of content that appears on our feeds, even when it seems popular or widely shared.
  • Advocate for stronger, enforceable regulations that go beyond voluntary self-regulation.

Unless social media platforms are held accountable through stronger policies and oversight, they will continue to profit from the chaos they help create.

What Needs to Change and How We Can Help

The study makes it clear: disinformation is not an isolated problem that can be solved by any single entity. It is a systemic issue requiring a multi-faceted approach.

Governments, tech companies, civil society, and individual users all have a role to play in curbing the spread of false information.

Here’s what needs to change—and what we, as everyday users, can do to help.

Stronger Regulation: Holding Platforms Accountable

One of the study’s key findings is that voluntary self-regulation by social media platforms has failed (Iosifidis & Nicoli, 2021, p. 65).

Tech companies have little financial incentive to crack down on disinformation, as their profits are tied to engagement rather than accuracy.

What needs to change:

  • Governments must require greater transparency in algorithms—platforms should disclose how content is ranked, promoted, and moderated.
  • Laws should hold tech companies accountable for hosting and amplifying disinformation, particularly when it leads to real-world harm.
  • Policies like the European Union’s Digital Services Act should be expanded globally to enforce stronger oversight of misinformation and harmful content.

What we can do:

  • Advocate for better regulation of social media platforms by supporting policies that demand accountability.
  • Stay informed about legislation on digital governance and participate in public discussions.

Digital Literacy: Building an Informed Society

The study highlights how misinformation flourishes in environments where people lack the skills to critically evaluate online content (Iosifidis & Nicoli, 2021, p. 118).

Media literacy must be a core part of education, helping individuals recognize manipulation tactics and fact-check sources effectively.

What needs to change:

  • Schools should integrate digital literacy programs that teach students how to identify misinformation and assess credibility.
  • Governments should fund public awareness campaigns that promote fact-checking and critical thinking.
  • Employers and organizations should train employees on disinformation risks, especially in fields like journalism, politics, and public health.

What we can do:

  • Improve our own media literacy by learning how to verify sources and recognize misleading content.
  • Share fact-checking tools like Snopes, PolitiFact, or the BBC’s Reality Check with friends and family.
  • Encourage schools and workplaces to adopt digital literacy training as a standard practice.

Tech Innovation: Using AI and Verification Tools Wisely

While technology has fueled the disinformation crisis, it can also be part of the solution.

Emerging tools like AI-powered fact-checking, blockchain-based verification, and public-interest algorithms offer hope for a more trustworthy digital landscape.

What needs to change:

  • Social media companies should invest in AI-driven misinformation detection, ensuring false content is flagged before it goes viral.
  • Research institutions should explore blockchain-based verification for news articles, preventing tampering and ensuring transparency.
  • Platforms should prioritize public-interest algorithms that promote credible news sources rather than clickbait.

What we can do:

  • Use browser extensions and fact-checking tools that help detect misinformation, such as NewsGuard or the Google Fact Check Explorer.
  • Support news organizations that invest in investigative journalism and AI-assisted verification.
  • Be skeptical of deepfake videos and AI-generated content, learning how to spot digital forgeries.

Community Engagement: The Role of Everyday Users

At the individual level, combating disinformation starts with how we interact with digital content.

The study emphasizes that social media users are not just passive consumers—we actively shape the information ecosystem by what we choose to share, challenge, or ignore (Iosifidis & Nicoli, 2021, p. 85).

What needs to change:

  • Social media companies should empower users with better reporting tools and clear guidelines on identifying misinformation.
  • Online communities should foster fact-based discussions, discouraging the spread of sensationalized or misleading claims.
  • Civil society organizations should mobilize grassroots fact-checking efforts, enabling volunteers to debunk false narratives.

What we can do:

  • Think before sharing—verify information before reposting.
  • Call out misinformation in a constructive way—instead of attacking, share credible sources and ask thoughtful questions.
  • Support fact-based journalism by subscribing to reputable news outlets and avoiding clickbait-driven sources.

The Bottom Line

Disinformation thrives in environments where misinformation is unchallenged, media literacy is weak, and tech companies operate without oversight.

But individuals have more power than they realize.

By becoming more informed, demanding accountability, and engaging responsibly online, we can help curb the spread of falsehoods and protect the integrity of our digital democracy.

Conclusion: The Power of an Informed Public

Disinformation is not just an abstract issue debated by policymakers and tech executives—it is a pervasive force that affects us all.

It shapes the way we perceive reality, influences our voting decisions, fuels social divisions, and even impacts public health.

The findings in Digital Democracy, Social Media, and Disinformation make it clear: digital misinformation thrives because it plays on human psychology and is amplified by algorithms designed for engagement, not truth.

However, the study also emphasizes that while disinformation exploits human behavior, it is not unstoppable.

Everyday internet users have the power to disrupt its spread by adopting critical thinking habits, questioning viral content, and holding both tech platforms and governments accountable.

What This Means for Us

  • Awareness is our first line of defense. Understanding how and why disinformation spreads makes us less vulnerable to manipulation.
  • Small actions matter. Choosing not to share an unverified claim, engaging in constructive fact-based discussions, and exposing ourselves to diverse sources of information all contribute to a healthier digital space.
  • We must demand accountability. Social media companies will not change their business models unless pressured by both public demand and strong regulation. Advocating for policies that prioritize transparency and public interest is crucial.

The battle against disinformation is not just about fixing social media—it’s about fostering a society that values truth over convenience, facts over sensationalism, and debate over division.

If we apply the lessons from studies like Digital Democracy, Social Media, and Disinformation, we can help create a digital environment where falsehoods struggle to take root and democracy remains resilient.

The choice is ours: continue being passive consumers of whatever appears in our feeds, or take an active role in shaping a more informed, responsible, and truth-driven online world.
