The Republican War on Knowledge: How the GOP Is Dismantling the American Mind

By Lucian Harrow

There is an elementary school in Miami-Dade County, Florida, where Amanda Gorman‘s inaugural poem — “The Hill We Climb,” delivered before forty million Americans on the steps of the Capitol on January 20th, 2021 — was pulled from library shelves and moved to a restricted section after a single parent filed a complaint. The stated objection, processed with the dutiful solemnity of an administrator who had learned the precise cost of resistance, was that the poem contained “indirect hate messages.” The poem is a twenty-three-line meditation on national renewal. Its author was, at the time of its delivery, the youngest inaugural poet in American history.

This is not a story about one excitable parent in one district in one state. It is a specimen — carefully mounted, properly labeled — of something considerably larger, considerably more deliberate, and considerably more consequential than the culture-war tableaux that cable television has trained us to regard as entertainment. The Republican war on knowledge is not a collection of local grievances that happened to accumulate. It is a program. And programs, unlike grievances, have architects.

One ought to be cautious here about the accusation of central coordination. The American right has rarely required a committee to move in concert. It has, instead, the more efficient mechanism of shared interest. What unites the school board member removing Toni Morrison from a Mississippi library with the senator demanding that climate scientists produce “balance” in their congressional testimony is not a memo but a method — the systematic erosion of the epistemic infrastructure upon which self-governance, however imperfectly, depends.

Democracy, after all, requires more than elections. It requires a citizenry that disagrees productively about what ought to be done while agreeing, at least approximately, about what is the case. When that second condition is made politically optional, what remains is not democracy but its theatrical scaffolding: the voting booth, the podium, the choreographed pantomime of deliberation conducted without the underlying substance. Ignorance, in sufficient concentration, becomes its own form of governance.

The Bibliographic Bonfire and Its Bookkeepers

The scale of what has happened to American school libraries since 2021 deserves more than the somewhat quaint euphemism “book bans” — a phrase that conjures Savonarola and seems, to modern ears, too operatic to be quite real. PEN America, which has tracked these removals with the meticulous determination of an archivist who refuses to be fooled, documented 3,362 instances of book removal in 182 school districts across 37 states during the 2022-23 academic year — a figure representing a 33 percent increase over the preceding year, and one that continued its climb through 2024, when cumulative tracking across the prior three years exceeded ten thousand individual instances.

The books are not obscure. They include works of established literary standing — The Kite R u nner, The Bluest Eye, Gender Queer, All Boys Aren’t Blue — alongside picture books depicting families that happen to contain two mothers, histories of American slavery that decline to sentimentalize its practitioners, and scientific primers that explain, without apology or circumlocution, how human bodies develop. The pattern of targeting is neither random nor naive. Challenged books cluster, with the reliability of a geological survey, around three coordinates: racial history, sexuality, and any account of the American past that refuses to be flattering.

The legislative architecture supporting these removals is equally deliberate, which is to say, entirely unashamed. Florida’s House Bill 1467, signed by Governor DeSantis in March 2022, required that all materials in school libraries be individually reviewed and approved by a certified media specialist before students could access them — a provision that, in practice, cleared shelves wholesale while review queues stretched across months. Texas passed House Bill 3979 in 2021, restricting the manner in which concepts related to systemic racism could be taught in public schools. Arkansas followed. Tennessee followed. The dominoes did not fall; they were arranged and then pushed.

Consider what is actually being excised from the American classroom. Not merely content — though the content matters — but capacity. Education, at its most defensible, is not the delivery of approved conclusions. It is the cultivation of the tools required to interrogate them. The student who has never encountered a perspective that contradicts the one received at home is not educated; she is inoculated — against complexity, against productive doubt, against the discomfort that precedes understanding. She may navigate the prescribed terrain with confidence. She will be helpless when she leaves it.

The advocates of these measures will say they are protecting children. They are doing something more consequential. They are forming adults.

The Manufactured Doubt Machine

If the assault on education is the Republican war on knowledge prosecuted in the present tense, then climate denialism is the same war prosecuted in the future tense — designed not merely to prevent action now but to ensure that the epistemic capacity required to understand the problem is methodically dismantled before the consequences become politically undeniable.

The scientific consensus on human-caused climate change is, at this point, as close to settled as science — an inherently self-revising and probabilistic enterprise — ever arrives. The IPCC’s Sixth Assessment Report, compiled across 2021 and 2022, drawing on the peer-reviewed work of thousands of researchers across dozens of countries, concluded that human influence has warmed the atmosphere, ocean, and land surface unequivocally, and that many of the resulting changes are unprecedented across centuries, if not millennia. This is not a contested finding among the scientists who study it. The contest, such as it is, takes place almost entirely outside the peer-reviewed literature — in congressional hearing rooms, on cable news panels, and in the op-ed pages of publications funded, directly or indirectly, by industries with material interests in the perpetuation of doubt.

The mechanism, as Naomi Oreskes and Erik Conway documented with forensic precision in Merchants of Doubt (Bloomsbury, 2010), was borrowed wholesale from the tobacco industry’s decades-long campaign to manufacture scientific uncertainty about the relationship between smoking and lung cancer. Establish doubt. Fund the skeptics. Demand impossible certainty before any action. Reframe consensus as the symptom of bureaucratic capture. The playbook is old; its application to climate science is, by now, a matter of historical record rather than allegation — established in part through the discovery and analysis of internal corporate memoranda from major fossil fuel companies, documents demonstrating that some knew the science was settled while publicly disputing it for decades.

What has evolved, in the contemporary Republican iteration of this project, is the audacity of the target. It is no longer sufficient to question the models, the data, or the methodology. The institution itself must be discredited. The EPA, NOAA, NASA’s climate research division — each has been subjected, during periods of Republican executive power, to a peculiar form of institutional vandalism that disguises itself as fiscal responsibility: budget cuts, personnel purges, and the removal of scientific findings from official government websites. This is not policy disagreement about remedies. It is epistemicide — the deliberate and systematic killing of the mechanisms by which a society knows things at all.

The cost is not merely environmental, though the environmental costs are arriving on schedule. It is adaptive. For every year a society spends manufacturing uncertainty about the nature of a problem, it forfeits the institutional capacity, the public tolerance, and the political will required to address it. The republic is not only heating. It is forgetting how to respond.

The Algorithmic Architecture of Organized Unreality

The Republican war on knowledge would be a manageable, provincial affair — a collection of school board squabbles and congressional postures — were it not for the digital infrastructure that has transformed what might otherwise be local prejudice into a national epistemological crisis.

One ought to be precise about what the internet has and has not accomplished. It has not, as its more credulous prophets once promised, democratized truth. It has democratized the production and distribution of authoritative-seeming falsehood while simultaneously dismantling the institutional structures — newspapers with editorial standards, broadcast regulations, peer-review gatekeeping — that historically provided, however imperfectly, some filtration between assertion and publication. The result is not a marketplace of ideas. It is an ecosystem. And ecosystems do not tend, in the absence of any organizing pressure, toward balance. They tend toward the dominance of organisms best adapted to prevailing conditions.

In this particular environment, the organism best adapted is not the carefully sourced dispatch but the emotionally charged provocation: the claim that confirms what the audience already suspects, that requires no verification because it already feels true, that travels at the speed of outrage while the correction crawls at the speed of evidence. This dynamic was not invented by the political right. But the political right — with greater tactical ruthlessness and, it must be said, considerably fewer scruples about the consequences — has proved more adept at exploiting it. The disinformation ecosystem now surrounding Republican politics, encompassing claims about election integrity, vaccine safety, climate conspiracy, and educational indoctrination of children, is not the spontaneous effusion of a legitimately skeptical citizenry. It is, in significant and documented measure, a produced phenomenon — the result of deliberate investment in content production networks, social media amplification strategies, and the cultivation of media personalities who deliver ideologically consistent misinformation to audiences measured in the tens of millions.

The deepest psychological damage is not inflicted on those who believe the specific lies. It is inflicted on those who can no longer determine, with any confidence, what the difference between a lie and a fact might look like — who have concluded, not entirely irrationally given the information environment in which they are submerged, that the distinction may not be worth pursuing. Epistemic learned helplessness is the most corrosive and durable product of the Republican war on knowledge. It survives the exposure of individual lies because it operates at a more fundamental level: it destroys the belief that the truth is knowable, and therefore worth knowing.

When truth is always contested and expertise always compromised, the most rational available response is to stop asking. The architects of this project understood this. That is what makes it a project.

What the Skeptical Reader Is Entitled to Say

At this juncture, the skeptical reader — and one has always preferred the skeptical reader to the credulous one — is fully entitled to register an objection. Is this not merely the perennial lament of one political faction about another? Has the American left not demonstrated, in its own seasons, an appetite for the suppression of inconvenient ideas: the disinvited speakers at universities whose views were deemed insufficiently progressive, the conflation of intellectual discomfort with demonstrable harm, the substitution of tribal consensus for genuine inquiry?

The objection is not without merit, and it deserves a serious answer rather than the dismissive roll of the eyes it too often receives from those who share its target.

Yes. The pressure campaigns that have succeeded, at various American universities, in disinviting speakers whose views caused distress represent a genuine threat to the culture of free inquiry — one that the left has too frequently excused on the grounds that the speakers in question were not worth hearing. The conflation of discomfort with harm is an intellectual error regardless of who commits it, and the left has committed it with enough frequency and complacency to earn critique.

But false equivalence is also an intellectual error. And it is the more dangerous one, precisely because it wears the comfortable clothing of even-handedness. The occasional disinvitation at a private university and the systematic, policy-level, legislatively enacted program of book removal from public school libraries are not in any reasonable measure equivalent phenomena, and treating them as such is not fairness but the mere appearance of its simulation. One represents the excesses of institutional capture at the margins. The other represents a documented and sustained effort to rewrite the informational architecture of American public education across thirty-seven states. The distinction is not one of degree. It is one of kind.

The Uncharted Cartography

Democracies have survived economic collapse. They have survived military catastrophe, constitutional rupture, and the long, unglamorous grind of institutional decay. What they have not previously been subjected to — and here the American experiment is entering genuinely novel territory — is the deliberate and well-funded dismantling of the shared epistemic preconditions for democratic deliberation itself.

The architecture of the assault is not difficult to describe once you have agreed to look at it directly. The local school board removes the book. The state legislature provides the mechanism. The senator performs the skepticism at the committee hearing. The think tank produces the doubt on schedule. The cable host amplifies the outrage. The algorithm buries the correction and promotes the provocation. And at the foundation of the entire structure, the political party that has calculated — not incorrectly, as an electoral arithmetic, whatever one thinks of it as a moral one — that an electorate incapable of distinguishing between information and propaganda is more reliably governable than one that can.

None of this is subtle. It has simply benefited from our collective disinclination to call a program by its name.

The republic, if it endures this period, will not endure it by accident or inertia. It will endure it because enough citizens decide, in sufficient numbers and with sufficient persistence, that the distinction between knowing and believing is worth the effort of defending. That the question “is this true?” is worth asking even when the answer is inconvenient, even when the asking is lonely, even when the architecture of the information environment has been deliberately engineered to make the question feel naive.

That is not a comfortable position in an age that has decided comfort is a constitutional entitlement.

But then, the most important positions rarely are.
