The Algorithm’s Inquisition: How Social Media Redefined the Authority of Knowledge

We live in a paradoxical age. Never before has humanity had access to so much information, and yet rarely in recent history has verified knowledge been so threatened. Social media has radically transformed the way people, especially young people, interact with information. This interaction is intense, constant, and seemingly democratizing, but behind that apparent freedom lies a profound phenomenon: the silent replacement of traditional epistemic authority with a new form of authority based not on knowledge, but on identity and tribal belonging.

For centuries, epistemic authority, that is, the legitimate right to be trusted as a source of truth, was built on verification: evidence, peer review, accumulated experience, rigorous study. Scientists, scholars, and professionals earned credibility by demonstrating that their claims withstood scrutiny. Today, in the digital ecosystem, that logic has been inverted. Authority is no longer earned through verification, it is granted through belonging. An influencer with millions of followers does not need to demonstrate any competence in medicine, economics, or science for their word to be received as truth by their audience. It is enough that they represent the values, lifestyle, or beliefs of a particular group. This can be called the shift from truth by verification to truth by identity, a claim is accepted as true not because it has been proven, but because it comes from someone we identify with.

This shift is more dangerous than it appears at first glance. If truth depends on identity rather than evidence, then what spreads is no longer knowledge, it is ignorance disguised as conviction. And what is truly alarming is that this is a confident ignorance, an ignorance that does not recognize itself as such, which makes it nearly immune to correction. When someone shows us we are wrong, the reaction is not to update our belief but to defend it more fiercely, because contradicting it no longer feels like learning, it feels like betraying the tribe. This mechanism, which psychology has documented as the backfire effect, explains why rational fact checking rarely changes opinions deeply anchored in identity.

To this tribal dynamic is added a second decisive factor: the economic model of digital platforms. These were not originally designed as tools for mass manipulation, but as spaces for people to share content easily. However, their evolution into an attention marketplace completely changed their incentives. Today, what prevails on a social network is not necessarily what is most viewed organically, but what is most economically promoted. Anyone with money can pay to amplify a message, regardless of whether it is true or false, as long as it generates a strong emotional reaction, outrage, fear, excitement. The algorithm does not distinguish truth from falsehood, it distinguishes what keeps people watching from what does not. The result is a lethal combination, identity predisposes people to believe, and money guarantees that those beliefs are seen again and again, while accurate information, usually less spectacular, is buried under the noise.

This phenomenon, though accelerated by digital technology, is not without historical precedent. Before the Inquisition consolidated its control over thought, humanity had already produced genuine, verifiable knowledge: Greek astronomy, geometry, classical medicine, natural philosophy that sought to explain the world through observation and reason. That legacy did not disappear for lack of intellectual merit, it disappeared because the power structures of the time decided that truth had to be subordinated to doctrine. The clearest case is that of Nicolaus Copernicus and Galileo Galilei, whose astronomical observations demonstrated that the Earth revolved around the Sun. The Church condemned that evidence because it contradicted its doctrinal authority, forced Galileo to recant under threat, and banned Copernicus’s work for centuries. Giordano Bruno, for defending similar ideas, was burned at the stake in the year sixteen hundred. This was not an absence of knowledge, it was verified knowledge deliberately displaced by an authority that would not tolerate competition.

What happened then is structurally identical to what we experience today: an established authority, unable to tolerate the loss of its monopoly on truth, chooses to suppress or displace knowledge rather than confront it with evidence. Society took centuries to rebuild institutions capable of restoring some epistemic order: professionalized universities, scientific societies with peer review, and eventually journalism with ethical standards.

In this context, universities remain, despite their limitations, one of the few institutions structurally oriented toward verification rather than virality. Their function is not to entertain or generate followers, but to form people capable of critical thinking, something radically different from simply influencing their emotions. Precisely for this reason, it is understandable, though deeply troubling, that certain sectors of the influencer ecosystem actively promote distrust of higher education. An educated population is a harder population to convince through the logic of truth by identity. Delegitimizing universities is not an accidental side effect, it is, in many cases, a survival strategy for those whose influence depends on the absence of critical thinking in their audience.

All of this raises a question that transcends technology: are digital platforms a space for human flourishing, or have they become an instrument that silently erodes the collective capacity to know the truth? The Inquisition of our time does not have a single face, but two, complementary to each other. The algorithm performs the institutional function, filtering, promoting, and punishing ideas according to criteria unrelated to truth, with the crucial difference that it no longer needs tribunals or stakes, it operates invisibly, through code. Influencers, for their part, perform the function once carried out by preachers and local tribunals: they are the ones who carry out, before the audience, the verdict the algorithm has already decided to amplify, and who give a human, relatable, credible face to a message that would otherwise be just cold data. Just as the historical Inquisition depended on both its legal structures and its preachers to impose itself on collective conscience, today’s digital Inquisition needs both the algorithm that decides what gets spread and the influencer who legitimizes it before their own tribe. Just as Galileo was silenced for challenging dogma with evidence, today rigorous knowledge can be silenced simply for not being profitable, for not generating enough outrage or excitement to compete in the attention marketplace, while those who do master that emotional language become, without fully intending to, the new gatekeepers of what most people will consider true.

For this reason, the answer cannot be limited to restricting young people’s access to these platforms. A deeper transformation is required: governments, technology companies, and educational institutions must take responsibility for redesigning the incentives that today reward emotion over evidence. This is not a restriction on freedom, but an inescapable human responsibility to ensure that knowledge, and not ignorance disguised as identity, remains the foundation on which the future of humanity is built.
