For years, the dominant narrative has been clear: social networks are tearing society apart, fueling polarization, spreading hate, and giving voice to extremism. Commentators point to the rise of populist leaders, cultural divisions, and an increasing sense of political discord as evidence that platforms like Facebook and Twitter are distorting reality, radicalizing populations, and disrupting societal harmony like never before. Yet a growing body of research challenges this view. Far from being passive victims of manipulation, humans are inherently skeptical creatures equipped with the tools to filter information, resist propaganda, and evaluate messages critically. Rather than blaming technology for societal woes, the real challenge lies in addressing the preexisting divisions that social media merely amplifies.

Human Gullibility: A Longstanding Misconception
The belief that humans are easily swayed by demagogues, propaganda, or hateful rhetoric is nothing new. Philosophers and social theorists—from Plato to Marx—have long warned of the masses’ susceptibility to manipulation. Marx and Engels famously argued that the ideas of the ruling class dominate society, suggesting that individuals internalize beliefs contrary to their own interests. Similar arguments underpin critiques of religion, caste systems, and patriarchal ideologies. The assumption is clear: people are gullible, and powerful sources—whether religious leaders, political elites, or media moguls—hold sway over public opinion.
This view has carried into modern critiques of social media. Platforms like Twitter and Facebook, it is argued, allow demagogues and extremists to reach vast audiences, while algorithms trap users in echo chambers, reinforcing divisive ideas. However, as cognitive scientist Hugo Mercier and commentator Gordon Danning argue, this story oversimplifies human behavior and history.
Mercier’s work highlights the concept of epistemic vigilance—a set of cognitive tools humans have developed to evaluate information. Instead of blindly accepting messages, people instinctively check plausibility, compare claims against their background knowledge, and calibrate trust based on a source’s credibility. The idea that humans are “hardwired for gullibility” makes little evolutionary sense. Trust in communication would not have survived as a stable trait if it frequently led to costly mistakes. Instead, humans are surprisingly resilient to misinformation, especially when the stakes are high.
This skepticism can be observed even in situations often cited as proof of human gullibility. Solomon Asch’s conformity experiments, where participants agreed with blatantly wrong answers to fit in with a group, are widely misinterpreted. Most participants conformed only outwardly, refusing to change their internal beliefs. Similarly, Stanley Milgram’s obedience experiments, where individuals followed orders to administer what they believed were dangerous shocks, were less about blind obedience and more about trust in science as a credible authority. Once the scientific veneer was removed—by repeating the experiment outside a university setting—compliance dropped dramatically.
Propaganda: Amplification, Not Creation
If humans are naturally skeptical, why does propaganda appear to work? Historical examples, from Nazi Germany to the Rwandan genocide, are often presented as proof that messaging can drive populations to commit atrocities. Yet a closer examination reveals a more nuanced reality: propaganda does not create hatred or extremist beliefs out of nothing. Instead, it amplifies and coordinates sentiments that already exist.
The role of “hate radio” during the Rwandan genocide illustrates this point. Popular narratives claim that inflammatory broadcasts radicalized peaceful communities and led them to slaughter their neighbors. However, research by anthropologists and political scientists tells a different story. Ethnic tensions and conflict predated the broadcasts, and many perpetrators either ignored or misunderstood the messages. When the genocide began, radio became a logistical tool, instructing perpetrators where and how to act, rather than inspiring hatred.
Similarly, studies of Nazi propaganda show that its success depended on preexisting prejudices. Areas with no prior history of anti-Semitism remained resistant to anti-Jewish messaging, while regions with deep-rooted biases were far more receptive. Propaganda worked not by converting the unconvinced but by consolidating support and encouraging action among those already sympathetic.
This pattern holds in contemporary contexts as well. Social media does not manufacture polarization but reflects and magnifies societal divisions. For example, the rise of populist leaders like Donald Trump or Marine Le Pen cannot be attributed solely to Facebook’s algorithms. Their success stems from their ability to articulate grievances that preexisted the platforms. Economic inequality, cultural anxieties, and distrust in institutions created fertile ground for their rhetoric. Social media merely gave voice to these issues.
Social Media: A Mirror, Not a Cause
The idea that social networks are uniquely responsible for today’s polarization and hate crumbles under scrutiny. Historical examples remind us that divisive rhetoric and societal disruption long predate Twitter and Facebook. The printing press, for instance, fueled the Protestant Reformation, sparking centuries of religious wars. Newspapers in 19th-century America were highly partisan, contributing to political animosities that culminated in the Civil War.
Polarization in the United States, often blamed on social media, has been increasing since the 1970s. This trend began decades before the advent of Facebook or Twitter, driven by structural factors like economic inequality, urban-rural divides, and the erosion of trust in traditional institutions. Studies by Pew Research show that polarization is not confined to social media users but extends across society.
While critics point to the rise of “echo chambers” on social media, research shows that people are exposed to more diverse viewpoints online than in offline settings. Platforms like Twitter, for all their flaws, create opportunities for cross-partisan dialogue. A study published in Science found that while people gravitate toward like-minded content, they still encounter opposing views. Social networks amplify existing divisions but are not isolated bubbles of influence.
The Real Risks and Misplaced Solutions
None of this is to say that social media is harmless. It can amplify extremism, misinformation, and hateful rhetoric. However, these problems are not new, nor are they solely the product of algorithms. The danger lies not in ordinary people expressing controversial views but in elite-driven messaging that legitimizes violence or silences dissent. When governments or influential leaders endorse harmful ideas, they create a sense of impunity and embolden extremist behavior.
Efforts to combat these risks often miss the mark. Social media censorship, for instance, is not only ineffective but potentially counterproductive. Banning extremist voices can reinforce their sense of persecution, driving them to darker corners of the internet and further radicalizing them. Moreover, censorship provides authoritarian regimes with a convenient excuse to suppress dissent under the guise of combating “hate speech.”
The focus, therefore, should shift from silencing individuals to addressing the content and underlying causes of societal division. Hate speech and propaganda succeed when they resonate with preexisting biases or anxieties. Tackling economic inequality, improving education, and rebuilding trust in institutions are far more effective solutions than censoring tweets or tweaking algorithms.
Conclusion: Resilience Over Gullibility
The narrative that social media is uniquely responsible for polarization and societal disruption oversimplifies a complex reality. Humans are not blank slates, passively absorbing harmful ideas. They are discerning, skeptical, and equipped with cognitive tools to resist manipulation. Propaganda and hate speech amplify preexisting tensions, but they do not create them.
Blaming social media is convenient, but it distracts from addressing deeper societal issues—economic instability, cultural divides, and institutional failures—that fuel division
