Sectored vs. Networked Madness
When Politics Mimics Psychiatry
At first glance, the vocabularies of clinical psychiatry and political analysis share nothing in common. The former deals with individual suffering and disorders of perception; the latter decodes mass movements and electoral dynamics. Yet, in our era of extreme polarization, filter bubbles, and global conspiracy theories, an old distinction from French psychopathology offers an incredibly effective framework for understanding our political landscape: the opposition between sectored delusion (délire en secteur) and networked delusion (délire en réseau).
In psychiatry, these two terms describe how a false, unshakeable belief colonizes an individual's mind. Transposed into political sociology, they help explain how millions of citizens adhere to radical narratives, from the MAGA movement to pro-Putin nationalism and Benjamin Netanyahu’s populist bloc.
The Sector: Compartmentalized Rationality
In a clinical setting, a "sectored" delusion is a targeted anomaly. The patient harbors an absolute obsession with a single topic—for example, the certainty of being cheated on by their spouse (jealousy) or of having been defrauded by a local administration (grievance). Outside of this specific dark zone, their rationality remains entirely intact: they manage their finances, excel at their jobs, and maintain perfectly adapted social relations.
In politics, the "sector" explains the behavior of pragmatic or single-issue voters. These are well-integrated, educated citizens who do not believe in far-fetched theories, but who choose to sanctuary a specific domain, even if it means turning a blind eye to everything else.
Take the traditional Republican voter within the MAGA movement. This entrepreneur or corporate executive might be deeply annoyed by Donald Trump’s rhetoric and reject the idea of a stolen election in 2020. However, their sectored obsession—tax cuts or the appointment of conservative judges—becomes their sole compass. They compartmentalize their thinking, isolating the leader's outrageous behavior to consume only the specific sectoral benefit that interests them.
The same applies to a portion of the support for pro-Putin or pro-Netanyahu nationalism. In the sectored approach, adherence is surgical. For the former, the sector of imperial nostalgia or geopolitical distrust toward NATO takes precedence, eclipsing the corruption of the Russian regime. For the latter, it is the sector of existential security or religious nationalism: the voter ignores Netanyahu’s personal legal troubles or his populist drifts because they are convinced that he alone is the necessary military shield against external threats. In all these cases, reason is not destroyed; it is simply set aside on one specific point.
The Network: The Totalitarian, Self-Validating System
Conversely, a "networked" delusion (historically theorized by French psychiatrists Paul Sérieux and Joseph Capgras) is centrifugal. It starts from a single point and spreads like an oil slick or a spiderweb across the entirety of the subject's existence. For the networked patient, nothing happens by chance anymore. A delayed bus, a stranger's glance, a change in the weather, or a newspaper headline: everything is connected, interpreted, and integrated to feed a massive machinery of persecution.
This is where modern political sociology finds its most striking parallel. Contemporary populist movements have succeeded in creating genuine networked systems of thought—formidable machines designed to manufacture a global alternative reality.
Step into the "networked" version of the MAGA movement, heavily infused with QAnon mythology. Here, compartmentalization has vanished. Inflation, immigration, the war in Ukraine, Hollywood movies, and judicial rulings are no longer independent dynamics: they are the threads of a single conspiracy orchestrated by a globalist "Deep State." The system is hermetic: if the courts convict the leader, it is not because he broke the law, but because the judicial system is part of the enemy network. The proof of guilt becomes, through a logical inversion typical of delusion, the ultimate proof of persecution.
The pro-Putin state narrative operates on the exact same reticular architecture. Democratic revolutions in Russia's neighboring countries, sports sanctions for doping, energy crises, or societal shifts in the West are presented on Russian state television as a single, coordinated hybrid war aimed at destroying Russian civilization.
Among the most radical partisans of Benjamin Netanyahu, the network takes an internal turn. The national press, the Israeli Supreme Court, security services, and peaceful protesters are no longer actors in a vibrant democracy, but agents of a "left-wing elite" network colluding to overthrow the legitimate leader and the will of the people.
From the Clinic to Society: The Role of Algorithms
If this psychiatric distinction is so relevant today, it is because our technological infrastructure acts as an accelerator of political pathology. Social media algorithms are, by definition, network engineers.
The tragedy of our time is the forced transition from the sector to the network. A citizen may enter a movement through a simple "sector"—a legitimate concern about the economy, a religious sensitivity, or a security fear. But if they consume their information on digital platforms, the algorithm will progressively link this concern to others, creating artificial bridges. Economic anxiety gets connected to anti-immigration theories, which are interconnected with vaccine distrust, itself linked to global geopolitical conspiracies.
Within a few months, the compartmentalized rationality of the sector collapses under the weight of the spiderweb. The pragmatic citizen is transformed into a total militant, trapped in a system where every piece of news, even the most contradictory, paradoxically validates their initial belief.
Understanding the "madness" of our modern public debate is therefore not about insulting the intelligence of voters; it is about analyzing the architecture of their convictions. When facing a political interlocutor, the question is no longer just what they believe, but how they believe it: does their mind still function through watertight sectors, or is it already caught in the network?
