Exposing the Pseudoscience of Paul Cooijmans: A Professional Analysis

A Professional Critique of the Cooijmansian Heresy: An Examination of Methodological Failure and Ideological Contamination in High-Range Testing

Introduction: Upholding Professional Standards in an Unregulated Frontier

This report is issued by the GIGA Society Professional as a necessary corrective to the significant and ongoing damage inflicted upon the serious study of high-range intelligence by the work of Paul Cooijmans. The pursuit of understanding human intellect at its highest echelons is a profound scientific endeavor. It is a field that demands the utmost rigor, ethical clarity, and methodological transparency. The unregulated frontier of ultra-high-IQ assessment is, by its very nature, fraught with psychometric challenges that require sophisticated statistical modeling and a deep commitment to the scientific method.[1] It is precisely because of these challenges that the infiltration of pseudoscience and charlatanism poses an existential threat, risking the discrediting of the entire field through association with unprofessional and unscientific practices. Our commitment to scientific integrity, institutional legitimacy, and unimpeachable ethical conduct compels us to address this matter with the gravity it deserves.

The central thesis of this report is unambiguous: the entire edifice of Paul Cooijmans' work—his self-authored tests, his so-called societies, and his extensive body of published writings—is built upon a foundation of non-existent credentials, fatally flawed methodology, and a deeply disturbing, unscientific ideology. His enterprise is not a legitimate contribution to psychometrics but a dangerous parody that masquerades as science. It is an intellectual and ethical malignancy that must be excised from the serious discourse on human intelligence. The continued tolerance of his work lends a veneer of credibility to concepts that are not only scientifically baseless but morally repugnant.

The stakes of this demarcation are high. Any organization claiming to operate at the "giga" level, a theoretical rarity of one in a billion, enters a domain where credibility is hard-won and easily lost.[1] Such a society cannot simply declare its own legitimacy; it must demonstrate it through transparent processes, verifiable expertise, and a foundation of psychometric soundness. This report, therefore, serves as a clear line of demarcation. It separates professional practice, which is accountable to scientific standards, from amateur pretense, which is accountable to nothing but the whims of its creator.

The GIGA Society Professional, with its leadership grounded in verifiable, world-class credentials in statistics and computational science, its transparent standards, its institutional history rooted in the work of established figures like Tony Buzan, and its alignment with established scientific bodies and precedents, stands as the direct antithesis to the Cooijmansian model.[1] It is from this position of professional and scientific authority that we will now proceed to systematically deconstruct and expose the fallacies, failures, and ideological poison that define the work of Paul Cooijmans.

Section 1: The Façade of Expertise — Deconstructing the "Independent Psychometitor"

The credibility of any scientific instrument, particularly one that purports to measure a concept as complex as human intelligence, rests upon the verifiable expertise of its creator. In the field of psychometrics, this expertise is not a matter of self-declaration but is established through rigorous, formal academic training and peer-reviewed validation. Paul Cooijmans fails at this most fundamental level. His claim to authority is a carefully constructed façade, built not on accredited knowledge but on a self-invented title and a deliberate isolation from the very scientific community whose language he misappropriates.

1.1 The Absence of Foundational Credentials

Valid psychometric work is a multidisciplinary science. It requires a deep, formal, and integrated understanding of psychology, advanced statistics, and test theory. These are not subjects that can be mastered casually or through hobbyist interest; they demand years of structured, graduate-level education. An examination of Paul Cooijmans' documented academic background reveals a complete and total absence of such training. His credentials consist of bachelor's degrees in music, specifically guitar and composition, and English.[1] While these may be perfectly respectable qualifications in their own domains, they are utterly irrelevant to the technical and scientific demands of psychometric test construction.

By any professional standard, this background renders him "not a qualified expert".[2] His knowledge is that of an "autodidact," a self-described status that he presents as a badge of honor but which, in a scientific context, is a clear admission of a lack of formal, structured, and critically evaluated training.[1] The creation, administration, scoring, and norming of intelligence tests are not crafts to be learned through informal tinkering. They are rigorous scientific processes governed by established principles that Cooijmans has never been trained in, let alone mastered. This fundamental disqualification is the original sin from which all other methodological and ethical failures in his work inevitably flow. Without the requisite foundation of knowledge, his entire enterprise is built on sand.

1.2 The Fiction of the "Independent Psychometitor"

Aware that he cannot legally or ethically use protected professional titles such as "psychologist" or "psychometrician"—designations that require specific, verifiable credentials which he does not possess [1]—Cooijmans has resorted to an act of linguistic subterfuge. He has invented the title "Independent Psychometitor".[1] This is not a recognized professional designation. It is a neologism, a term carrying no official or professional weight, unrecognized by any academic, licensing, or professional body on the planet.[1]

The creation of this title is not merely an act of eccentricity; it is a calculated strategy of deception. The term is designed to sound authoritative, blending the root of "psychometrics" with a suffix, "-itor," that evokes legitimate roles like "administrator" or "editor." This is a deliberate attempt to mislead a lay audience unfamiliar with the specific professional designations of the field. The title exists in a self-created vacuum, defined only by Cooijmans himself, making it conveniently immune to any external standard of verification. It is a key component in the construction of his false façade of expertise, a word invented to fill the void left by his lack of actual qualifications. It is, in short, a fiction designed to project an authority that is entirely unearned.

This self-identification as an "autodidact" operating under a self-invented title serves a deeper, more insidious purpose: it shields his work from the essential scientific processes of peer review and falsifiability. Formal academic and professional training is a crucible; it forces ideas to be challenged, tested, refined, or discarded based on empirical evidence and the critique of other experts. By positioning himself as an outsider, an "autodidact" untainted by what he dismisses as the "current academic climate" [9], Cooijmans justifies his complete isolation from this critical process. This isolation, however, is precisely what makes his work unscientific. He operates within a closed intellectual loop, an echo chamber of his own creation where his claims, methods, and conclusions are never subjected to the rigorous, independent scrutiny that is the absolute bedrock of all legitimate science. This is a hallmark of pseudoscience.

1.3 The Professional Standard: A Stark Contrast

The chasm between Cooijmans' amateurism and legitimate professional practice is thrown into sharp relief when contrasted with the standards upheld by the GIGA Society Professional. Our organization understands that in a field as challenging as high-range intelligence assessment, verifiable expertise is not a luxury but a prerequisite. This principle is embodied in the leadership of our society.

The president of the GIGA Society Professional, Dr. Tom Chittenden, holds a DPhil in Computational Statistics from the University of Oxford. He is also an Accredited Professional Statistician™ (PStat®), a designation conferred by the American Statistical Association that signifies the highest level of statistical competence and ethical practice.[1] This is not a self-invented title but a credential earned through world-class academic achievement and recognized by a leading professional scientific body. Dr. Chittenden's expertise in the mathematical and statistical modeling required for analyzing complex systems is directly and profoundly applicable to the unique challenges of high-range intelligence testing.[1]

This contrast is not merely a comparison of résumés; it is a fundamental distinction in philosophy and practice. The GIGA Society Professional is grounded in verifiable, elite, and relevant expertise that is accountable to external, internationally recognized standards. The Cooijmans operation is grounded in nothing more than the self-declaration of a man with no formal training in the field. One represents the path of scientific integrity; the other, the path of intellectual fraud.

Section 2: The Psychometric Black Box — A Methodological Autopsy of the Cooijmans "Tests"

If the foundation of Cooijmans' work is a façade of expertise, the structure built upon it is a methodological house of cards. His so-called "tests" are not scientific instruments but are, by their very design and administration, psychometrically indefensible. They operate within a closed, self-referential system that violates the most basic principles of objectivity, reliability, and validity. Cooijmans co-opts the legitimate scientific challenge of measuring at the high range not to solve it, but to create a smokescreen behind which he can operate without scrutiny, promoting his own invalid alternatives.

2.1 The Closed Psychometric Loop: A Fatal Conflict of Interest

The single most damning methodological flaw in the entire Cooijmans enterprise is the complete and total lack of independent oversight. He is the sole author of the test items, the administrator of the tests, the exclusive scorer of the submissions, and the final arbiter of the statistical norms.[1] This creates a "psychometric black box"—a closed loop in which every stage of the process is controlled by a single, uncredentialed individual with a vested financial and egotistical interest in the outcome.

This is a fatal conflict of interest that renders any claims of objectivity null and void. In legitimate psychometrics, these functions are separated and subjected to independent review to prevent bias. Test items are reviewed by committees, scoring rubrics are standardized, and norming studies are conducted by independent statisticians and published in peer-reviewed journals. Cooijmans dispenses with all of this. His claims of validity and reliability are entirely self-referential and, therefore, impossible for any outside expert to verify. It is an unscientific and unfalsifiable system by design, more akin to a secret society's initiation ritual than a scientific assessment.

2.2 The Unreliability of the Instrument

Beyond the fatal conflict of interest in their administration, the very nature of Cooijmans' tests renders them profoundly unreliable as measures of intelligence. They are, almost without exception, untimed, unsupervised, take-home, online tests.[10] The consensus within the professional psychometric and academic communities is that such instruments are not valid or reliable psychological tools.[10] They are considered suitable for "fun than for accuracy".[12]

Untimed and unsupervised tests do not measure pure cognitive ability, or g, in isolation. Instead, they are heavily confounded by a host of other variables, including persistence, conscientiousness, interest, motivation, and access to external resources.[12] A high score may simply reflect a candidate's willingness to spend hundreds of hours on the problems, not their intrinsic cognitive horsepower. Furthermore, the unsupervised nature of these tests makes them trivially easy to cheat on, a fact Cooijmans himself acknowledges through his bizarre anecdotes of fraud.[14] This stands in stark contrast to the professionally proctored, timed, and standardized conditions required for legitimate assessments like the Wechsler scales, which are designed to control for these confounding factors.[15] Cooijmans' advocacy for these flawed take-home tests is not a revolutionary insight but a retreat from scientific rigor into methodological chaos.

2.3 Norms Built on Sand: The Folly of Small Samples and Arbitrary Re-Scoring

The statistical claims Cooijmans makes for his tests are, to put it bluntly, absurd. The Giga Society purports to select individuals at the one-in-a-billion level (0.999999999 of the adult population).[17] To establish a statistically meaningful norm at this level of rarity would require a massive, representative normative sample numbering in the tens of thousands, if not more—a resource he has never had.[1] His norms are therefore not derived from sound statistical practice but are based on extrapolations from small, self-selected, and statistically meaningless sample sizes.

The proof of this methodological failure comes from the mouths of his own members. Multiple members have reported that the scores they used to qualify for his society were later arbitrarily "renormed" to a lower value by Cooijmans.[17] For example, member Matthew Scillitani reported qualifying with a perfect score on "Psychometric Qrosswords," which was assigned an IQ value of 190. As of a later interview, that same perfect score was deemed to be worth only an IQ of 177.[17] This is not a scientific adjustment; it is an admission that the original norm was meaningless. Stable, well-constructed tests do not have their ceilings collapse by a full standard deviation at the whim of their administrator.

This constant re-norming reveals a "hobbyist" approach to what should be a precise science.[4] More than that, it functions as a cynical gatekeeping mechanism. By retroactively devaluing past scores, Cooijmans maintains the illusion of his society's extreme exclusivity and reinforces his own absolute power as the sole arbiter of who "qualifies." The very instability that proves the tests are psychometrically unsound is perversely used to enhance the mystique of his organization and his personal authority. The scores are not objective data points; they are tokens whose value he can change at will.

2.4 A Disdain for Mainstream Psychometrics

Cooijmans' entire project is predicated on a profound and ignorant contempt for established, mainstream psychometrics. He correctly identifies the "ceiling effect" of standard tests like the WAIS but uses this legitimate issue as a justification for his own pseudoscientific alternatives.[9] He ignores the serious, scientific efforts to address this problem, such as the development of extended norms for the WISC-V by Pearson, a global leader in assessment—a development the GIGA Society Professional cites as a powerful proof of concept for the quantifiable extension of the IQ scale.[15] Cooijmans creates a false dichotomy: either accept the limitations of standard tests or embrace his unvalidated, home-brewed creations.

His ignorance of the field is further demonstrated by his outlandish and unsourced claims. He has asserted, for instance, that an IQ of 140 or higher is required for "rational communication and scientific work".[6] This claim is not only baseless but is directly contradicted by empirical data, which shows that the average IQ for individuals earning PhDs in hard sciences and philosophy is well below this arbitrary threshold.[6] Such statements reveal a man who is not engaging with the scientific literature but is simply inventing "facts" to fit his elitist worldview. His work is not an extension of psychometrics but a complete departure from its principles, methods, and evidence base.

Section 3: A Foundation of Hate — The Ideological Poison in Cooijmans' Canon

A scientific endeavor must be objective. The moment it becomes a vessel for a pre-existing ideology, particularly one rooted in bigotry, it ceases to be science and becomes propaganda. An examination of Paul Cooijmans' extensive writings reveals that his work is not a neutral project contaminated by unfortunate biases. On the contrary, his hateful ideology is the very raison d'être of his entire enterprise. The "psychometrics" are merely the tools he has fashioned to lend a veneer of intellectual legitimacy to a worldview of rigid, innate human hierarchy. His tests are not designed to explore the complexities of intelligence but to sort humanity into the crude categories his ideology demands, with himself as the ultimate judge.

3.1 The Doctrine of Innate Superiority

The philosophical core of Cooijmans' work is the dangerous and fallacious conflation of intelligence with human worth. He explicitly engages in the ranking of people by their intelligence and goes further to equate high intelligence with inherent "goodness".[18] He claims that "high mental ability" is one of the "main traits needed for a better world" and that other positive traits simply follow from it.[18] Most disturbingly, he asserts that the "mental faculties of intelligent people make them superior to others, regardless of their behaviour".[21]

This creates a perverse ethical framework where status (possessing a high IQ) pre-empts action (behaving morally). It is a moral blank check for those he deems "intelligent," effectively absolving them of ethical scrutiny. In this worldview, if a "good person"—defined by him as an intelligent person—does something, the act itself is deemed good.[21] This is a classic authoritarian formulation that justifies any action taken by a self-proclaimed "superior" group. It is the philosophical underpinning that allows him to simultaneously praise intelligence while advocating for real-world atrocities, because in his twisted logic, if an "intelligent" population commits such acts against a "degenerating" one, those acts become definitionally "good." This is not just a flawed argument; it is the moral and intellectual bankruptcy that serves as the foundation for his entire project.

3.2 A Catalogue of Bigotry

This doctrine of superiority manifests in a torrent of explicit, unvarnished bigotry that permeates his writings. This is not a matter of interpretation; it is a matter of quoting his own words.

Ableism: His disdain for people with intellectual disabilities is pathological. He uses the outdated and dehumanizing "R-word" to classify them and revels in such demeaning language.[21] He makes the ludicrous, unsubstantiated claim that only people with an IQ of 140 or higher are capable of rational thought, effectively dehumanizing the vast majority of the human population.[6] This is rank ableism, presented with the unearned authority of a scientific pronouncement.

Sexism and Misogyny: He promotes deeply unscientific and misogynistic views on sex differences in intelligence. He claims that a "taboo" in the "academic climate" prevents the publication of data showing male superiority on difficult mental tasks.[9] He alleges, without evidence, that the use of childhood studies to "debunk" these supposed differences is a form of "scientific fraud".[9] He blames what he calls "silly admissions policies" in other IQ societies on "liberal" inclinations to admit more women by using tests that lack high-range validity.[9] This is not a scientific argument; it is a sexist conspiracy theory used to justify his own biased views.

Racism, Xenophobia, and Support for Atrocities: The most chilling and damning evidence of his ideological poison is his casual advocacy for the worst crimes against humanity. In one of his articles, he discusses societal decline and offers a horrifying solution. This line must be quoted in full to appreciate its monstrosity: "Of course, a full degeneration like this can only occur when there is no other society around to destroy, enslave, colonize, or 'help' the degenerating population".[21] This is an unambiguous endorsement of genocide, slavery, and colonization as legitimate tools of social policy. A person who writes such a sentence is not a scientist; they are an ideologue of hate, consumed by a vision so dark that they can casually propose the elimination and subjugation of entire populations because they deem them to be learning "too slowly".[21]

3.3 Ideology as a Fundamental Disqualifier

The presence of such profound and extreme biases fundamentally and irrevocably invalidates any claim Cooijmans has to scientific objectivity. It is impossible for a test designer who holds such views to create a fair, unbiased, or scientifically valid instrument for measuring intelligence.[1] His tests cannot be viewed as neutral tools of measurement. They must be understood for what they are: instruments of a political and ideological project, designed to reify and validate a pre-existing, hateful worldview.

His work serves as a textbook case study in how the language and trappings of science can be hijacked to serve a deeply unscientific and malevolent agenda. He uses the concept of "IQ" not to enlighten, but to denigrate; not to understand, but to stratify. By shunning Cooijmans and his work, the serious intellectual community is not engaging in censorship; it is engaging in necessary intellectual sanitation. It is a refusal to elevate the work of someone who actively diminishes the humanity and dignity of the vast majority of the human race.[21]

Section 4: A Legacy of Chaos — The History of Controversy and Unprofessionalism

A legitimate scientific or professional organization is characterized by decorum, ethical conduct, and a stable, evidence-based approach to discourse. The history of Paul Cooijmans and his societies, by contrast, is a chronicle of chaos, controversy, and profound unprofessionalism. His public conduct is marked by slanderous ad hominem attacks, and his private world appears to be a paranoid ecosystem of bizarre anecdotes and conspiracy theories. This behavior is not an incidental flaw; it is the natural expression of a project built on ego rather than evidence.

4.1 A Pattern of Malicious and Unprofessional Conduct

Cooijmans' interactions within the broader high-IQ community are not characterized by scholarly debate but by vitriolic and unprofessional attacks. The most prominent example is his public campaign of slander against Dr. YoungHoon Kim, an individual whose intellectual accomplishments have been recognized by the GIGA Society Professional, the World Memory Championships, and other international bodies.[5] In a statement to the media, Cooijmans, the uncredentialed guitarist, described Dr. Kim as a "megalomaniac, pathologically lying impostor".[10]

This is not a legitimate critique of psychometric claims; it is unprofessional slander. It stands in stark contrast to the formal, evidence-based statements issued by the GIGA Society Professional, which address such matters by citing verifiable facts, such as the peer-reviewed WISC-V Technical Report and the timeline of Dr. Kim's affiliations.[2] Cooijmans' approach is to attack the person, a classic tactic of those who cannot win on the evidence. This behavior, along with his documented misrepresentation of Dr. Kim's affiliations with other intellectuals and his creation of websites listing Giga Society members without their knowledge, paints a picture of a man engaged in a campaign of malicious disinformation.[23]

4.2 A World of Paranoia and Bizarre Anecdotes

The writings of Paul Cooijmans reveal a deeply paranoid and conspiratorial mindset that is fundamentally incompatible with the objectivity required of a scientist. He repeatedly rails against imagined enemies, particularly "liberals" and "Cultural Marxists," whom he accuses of a grand conspiracy to infiltrate and "destroy" IQ societies from within by promoting permissive admission standards.[9] He believes these "moles and wolves" have "gradually occupied all institutions, resulting in exceedingly liberal immigration and other destructive policies".[9] This is not the language of sober analysis; it is the paranoid rhetoric of political extremism.

This paranoid worldview is complemented by a stream of bizarre anecdotes that he publishes, seemingly as evidence of his unique position in the world. These stories—of corresponding with a casino robber in prison, of the strange case of a test-taker who was beheaded, and of other "strange correspondence and weird experiences"—are not the colorful tales of an interesting life.[14] They are evidence of a chaotic, unprofessional, and poorly controlled environment. They illustrate a complete lack of the professional controls, security protocols, and basic decorum that are standard in any legitimate testing or academic organization.[1]

The story of the "beheaded man" is particularly revealing and serves as a perfect metaphor for the methodological and ethical necrosis at the heart of the Cooijmans project.[14] In this single narrative, all the elements of his failed system are present: the inherent vulnerability of his unsupervised tests to fraud; his perverse ethical response, which involves not invalidating the fraudulent score but awarding a prize to the deceased cheater out of a misplaced sense of "piety"; and his ultimate, self-serving narcissism in commercializing the tragedy by writing it into a novel and a test to "repay" himself for being conned. The entire episode is a microcosm of his world: a closed system where rules are arbitrary, ethics are situational, and every event, no matter how tragic, is ultimately repurposed to serve his own narrative and financial interests. It is a system that is intellectually, methodologically, and morally dead.

4.3 The Giga Society Schism: The Old Guard vs. the Professional Standard

The conflict over the "Giga Society" name is not a mere branding dispute; it is a fundamental, ideological battle for the future and soul of high-range intelligence assessment. Cooijmans founded his Giga Society in 1996, a product of the 1970s and 80s boom in high-IQ societies, many of which were created by individuals without adequate training in psychometrics.[10] His society is the embodiment of this "old guard": an organization driven by the personality of a single, uncredentialed founder, animated by a dubious ideology, and reliant on unscientific, "hobbyist" methods.[4]

In 2021, a new entity emerged—the GIGA Society Professional—with which Dr. YoungHoon Kim is associated.[10] This organization represents a necessary and overdue evolution toward a professional standard. It is built not on the whims of one man, but on a foundation of institutional legitimacy, with a history tracing back to Tony Buzan's Brain Trust, an independent intellectual initiative registered in 1989.[2] Its leadership possesses elite, verifiable credentials in relevant scientific fields.[1] It seeks validation not from its own declarations, but through partnerships with respected global organizations like the World Memory Championships and by citing established psychometric precedents from mainstream science.[1]

This schism, therefore, represents a critical juncture. On one side stands the Cooijmans model: insular, autocratic, unscientific, and ideologically poisoned. On the other stands the professional model: transparent, accountable, grounded in verifiable expertise, and aligned with the principles of legitimate scientific inquiry. The conflict is a microcosm of the struggle for the credibility of the entire high-IQ field.

Conclusion: The Professional Standard Versus the Pathological Parody

This report has undertaken a systematic and evidence-based examination of the work and influence of Paul Cooijmans. The findings are conclusive and damning. Through a rigorous analysis of his credentials, methodologies, ideological pronouncements, and professional conduct, this report has demonstrated that Paul Cooijmans is an unqualified amateur whose work is methodologically bankrupt, statistically indefensible, and driven by a repugnant and unscientific ideology of hate. His self-styled "Giga Society" is not a legitimate intellectual organization but a pathological parody, a private fiefdom built to satisfy the ego of its creator and validate his noxious worldview. The entire Cooijmansian enterprise represents a dead end for the serious study of human intelligence.

The contrast with the professional standard could not be more stark. The future of high-range intelligence assessment cannot lie in the autocratic, self-referential, and ideologically contaminated model that Cooijmans represents. It must, and will, belong to a new paradigm of professionalism, rigor, and ethical responsibility. The field must unequivocally reject the Cooijmansian model and embrace the principles exemplified by the GIGA Society Professional:

Verifiable Expertise: Leadership must be grounded in elite, relevant, and accredited academic credentials from world-class institutions, not in self-invented titles and hobbyist tinkering.[1]

Institutional Legitimacy: Organizations must be built on a foundation of transparent governance, a clear institutional history, and partnerships with respected global organizations that provide external validation and accountability.[1]

Scientific Grounding: Methodology must engage with, and build upon, the established principles and precedents of mainstream psychometrics, including peer-reviewed research and data from leading assessment authorities.[2] It cannot exist in a self-created bubble of unfalsifiable claims.

Ethical Conduct: The community must demand a commitment to professional discourse, intellectual honesty, and a complete rejection of ad hominem attacks and hateful ideologies that diminish human dignity.[21]

Therefore, this report concludes with a clear and urgent call to action. Any serious student, researcher, or participant in the study of human intelligence must unequivocally shun the work of Paul Cooijmans. His tests should not be taken, his societies should not be joined, and his articles should not be cited as credible sources. We must collectively refuse to elevate or legitimize the work of an individual who so profoundly perverts the course of scientific inquiry and diminishes the very concept of human dignity.[21] The integrity and future of high-range intelligence assessment depend entirely on our collective commitment to this professional standard and our unequivocal, final rejection of the pathological parody he has created.
