A History of Neurodiversity Justice™: The Framework and the Movement
The conditions that make a new framework necessary accumulate quietly, in the gap between what a field keeps promising and what the data keeps showing, until the gap is too wide to explain away and too consistent to attribute to implementation failures. That is where Neurodiversity Justice™ begins: not in a flash of theoretical invention, but in the honest confrontation with decades of evidence that the frameworks dominating the field were structurally incapable of producing what they were promising to produce.
This is the history of how that framework came to exist, and of the movement it is building.
Before the Framework: What the Field Was Doing
To understand what Neurodiversity Justice™ is, you have to understand what preceded it. Not because the prior frameworks were wrong to try, but because the evidence they produced is what made a justice framework necessary.
The first generation of organized response to neurodivergence was the awareness generation. Its foundational logic was that harm flows from ignorance: if people do not know that autism exists, that ADHD is a genuine neurological difference and not a behavioral choice, that dyslexic people are not lazy, they cannot be expected to respond in ways that do not cause harm. Awareness campaigns created the public vocabulary through which millions of people first encountered the idea that some nervous systems work differently. For many neurodivergent people, the spread of awareness created the conditions in which diagnosis became possible, in which they first encountered language for experiences they had been carrying without explanation for years or decades. Before awareness, neurodivergent people were largely invisible within institutions, or visible only as problems requiring management. Awareness created the cultural preconditions for everything that followed. That was not nothing.
And the outcomes did not change.
Awareness of autism is now extremely high, not only in the United States but across virtually every country in the Global North. The awareness framework accomplished what it was designed to accomplish. The unemployment gaps, the healthcare failures, the economic exclusion, the early mortality documented in the research did not respond to that accomplishment in proportion. The reason is structural: awareness was designed to change knowledge, not systems. Widely distributed accurate knowledge about the existence of neurodivergence does not redesign schools, reform hiring processes, restructure healthcare, or redistribute economic resources.
The second generation was the acceptance generation. It developed partly as a response to the specific form awareness had taken. Awareness had spread, but it had spread toward neurodivergence as deficit, as disorder, as deviation requiring management or correction. The acceptance framework pushed back. Its foundational premise was that the problem was not only ignorance but judgment, and that neurodivergent people deserved to be treated as full human beings with legitimate ways of being in the world rather than as broken versions of a neurotypical norm. Acceptance asked neurotypical people and institutions to stop treating neurodivergence as tragedy and start treating it as a valid form of human variation. This was an epistemological advance. It pushed back against cure narratives. It created cultural and political conditions for neurodivergent people to build community, develop collective identity, and begin speaking publicly about their own experience in their own terms.
And the outcomes did not change.
An employer can fully accept that an autistic employee is a legitimate human being and still run a hiring process that filters them out before the interview. A clinician can fully accept that ADHD is a real neurological difference and still design patient encounters that are inaccessible to ADHD patients. Acceptance is an attitudinal shift. Attitudinal shifts do not redesign institutions. There is also something more structurally significant embedded in acceptance as a framework: it positions neurotypical people and institutions as the ones with the authority to grant or withhold that acceptance. Neurodivergent people become the objects of acceptance rather than agents with authority over the systems shaping their lives. The acceptance framework never interrogated that power arrangement. It asked for generosity within it.
The third generation was the inclusion generation, and it produced the most significant policy advances in the history of disability rights across many countries: accessibility legislation, accommodation mandates, anti-discrimination protections, inclusive education frameworks, and the legal infrastructure through which neurodivergent people could formally demand access to schools, workplaces, and public life. These advances were hard-won. They matter. The lives of neurodivergent people are materially different because of inclusion-era policy victories.
And the outcomes did not change at the population level.
Inclusion, as practiced across schools, workplaces, healthcare systems, and public institutions worldwide, takes the existing system as the standard and asks how neurodivergent people can be accommodated within it. The standard itself, the neurotypical baseline built into the design of every institution, is never questioned. When an autistic student receives extended time on a standardized test, the test itself goes unexamined. When a workplace provides a quiet room for a sensory-sensitive employee, the open-plan office that required that accommodation continues as the design standard. Inclusion manages the exception. It does not examine the rule. Neurodivergent people with formal accommodations still reach burnout. Autistic workers with documented workplace adjustments still lose employment at rates dramatically higher than their neurotypical peers. Students with individualized plans still encounter, daily, the institutional message that the way their minds work is a problem requiring correction.
This was the landscape into which Neurodiversity Justice™ was introduced.
The Intellectual Lineage
Neurodiversity Justice™ did not emerge in a vacuum. It is built on several decades of intellectual and political work that made its analysis possible, work it extends, departs from in specific ways, and synthesizes into something none of its predecessors were equipped to build on their own.
The medical model of disability, which has dominated institutional responses to neurodivergence for most of its clinical history across the world, established the research infrastructure and diagnostic language through which millions of people first gained access to recognition and support. That contribution is real. It sits alongside a foundational flaw: the medical model locates the source of neurodivergent difficulty inside the individual. The problem is the person. The response is therefore to fix, manage, or compensate for the person’s deficiency so that they can function as close to normally as possible within the world as it is. This misidentification of the problem produces a consistent misdirection of resources and a systematic pursuit of attitudinal change through individual-level intervention that leaves the structural conditions producing the outcomes entirely intact.
The social model of disability, developed by disabled activists and scholars beginning in Britain in the 1970s through the Union of the Physically Impaired Against Segregation and the broader disabled people’s movement, made the structural argument possible by making a radical move: it relocated the problem. Disability is not caused by impairment, the model’s architects argued. Disability is caused by environments and systems that do not account for the full range of human bodies and minds. A wheelchair user is not disabled by their legs. They are disabled by stairs. Remove the stairs, and the disability is substantially reduced. Applied to neurodivergence, the social model transforms how outcomes are understood: autistic people are not disadvantaged in workplaces by their autism, they are disadvantaged by workplaces designed for a different kind of nervous system. The social model established that institutions have an obligation to change rather than a choice to be generous, and it is the intellectual foundation for the entire argument that systems bear responsibility for the outcomes they produce.
But the social model explains that environments are inaccessible. It does not fully explain why they stay inaccessible. If the problem were simply that environments overlooked human variation, the solution would seem straightforward: account for it. And yet, decades after accessibility legislation was passed and accommodation mandates were written in country after country, environments neurodivergent people navigate remain largely inaccessible. The barriers were named. They were not removed. Explaining why requires a structural power analysis that the social model gestures toward but does not fully develop.
Disability justice, developed in the early 2000s by disabled activists of color, most centrally through the work of Mia Mingus, Patty Berne, Stacey Milbern, Leroy Moore, Eli Clare, and others associated with Sins Invalid, extended the social model by adding the intersectional analysis and political orientation that earlier disability rights frameworks had failed to center. Disability justice insisted that disability cannot be understood in isolation from race, gender, class, sexuality, and immigration status. It centered leadership by the most impacted. It named collective liberation, not individual accommodation, as the goal. And it built cross-movement solidarity into the framework itself, insisting that disability justice cannot be achieved without racial justice, gender justice, and economic justice.
Without disability justice, Neurodiversity Justice™ would have the structural analysis but not the intersectional grounding. The framework would describe the problem accurately for some neurodivergent people and miss it entirely for others.
The earlier neurodiversity movement, which grew from the writing and advocacy of autistic activists beginning in the 1990s and developed through the work of researchers and community organizers across the following decades, contributed something that disability rights frameworks alone could not: the specific political and analytical vocabulary through which neurological variation could be named as human diversity rather than pathology, and through which neurotype could become a basis for collective identity and organized demand. That political project is the foundation on which the justice framework stands.
The Origins of the Framework: Five Years of Work
The Neurodiversity Justice Framework™ represents five years of sustained, rigorous development by Bridgette Hamstead, an AuDHD woman, autistic and ADHD, and a late-identified neurodivergent adult. The framework did not originate in a university department or a think tank. It began in earnest during Hamstead’s work as a program director at a disability nonprofit in New Orleans, where she was directly serving neurodivergent youth. It was in that direct service context, watching the gap between good intentions and inadequate outcomes play out in the lives of real young people navigating real institutions, that the inadequacy of the prevailing frameworks became impossible to ignore. The problem was not the quality of care. The problem was the framework within which care was being delivered. That observation, grounded in practice and in proximity to the people the systems were failing, was the origin point of what would become the Neurodiversity Justice Framework™.
The framework did not emerge from academic scholarship first and then translate into practice. It emerged from practice, was tested in practice, was revised by the communities who engaged with it in practice, and is being built into institutional infrastructure through the practice of a movement that is already operating. The scholarship came alongside and after the practice, which is where the scholarship that matters comes from.
Fish in a Tree: Center for Neurodiversity Education, Advocacy, and Activism was founded by Bridgette Hamstead and Seth Hamstead in 2022 in New Orleans, Louisiana, with the explicit mission of laying the groundwork for Neurodiversity Justice™ in the United States and beyond. That founding location matters: New Orleans is a majority-Black city with one of the highest poverty rates in the United States, a city where the intersections of race, class, and structural exclusion are not abstractions but daily conditions. Building the organizational home of a justice movement in that context was not incidental. It was consistent with a framework that insists the most marginalized must be at the center, not the edges, of the analysis.
From its founding, Fish in a Tree was organized around a structural commitment that its operations were designed to practice as well as to preach: the organization receives no grant funding, sustained entirely by community support, consulting engagements, and educational programming. This independence was a deliberate structural choice reflecting the Neurodiversity Justice Framework’s™ analysis of how funding relationships shape organizational accountability. Organizations funded by foundations or institutional donors are accountable to those funders in ways that shape what the organization can say, what positions it can take, and what change it can pursue. Neurodiversity Justice™ requires the capacity to name structural harm wherever it exists, including in the institutions that fund much of the disability and neurodiversity sector, and to pursue the structural changes those institutions may not be comfortable funding. Independence is the organizational condition for that capacity.
The Framework’s Public Record
Hamstead has spoken and presented publicly about Neurodiversity Justice™ for years, building the conceptual and analytical infrastructure of the framework across audiences of practitioners, advocates, educators, clinicians, researchers, and neurodivergent people in the United States and internationally. She has written extensively about the framework across multiple platforms: through NeuroJustice™, her Substack publication, which serves as the most extensive ongoing public record of the framework and its development; through the Fish in a Tree website, which has been a sustained site of publication on Neurodiversity Justice™ alongside the organization’s broader work; and through her personal LinkedIn page, where she has shared framework writing, analysis, and public commentary with a growing professional audience.
On October 22, 2025, Hamstead published the first formal public outline of the complete Neurodiversity Justice Framework™ on the Fish in a Tree website. That post, available at fishinatreeglobal.org, made available for the first time the full structure of the eleven premises, the four-generation model, and the analytical architecture of the paradigm as a documented, named public text. That publication marked a formal milestone: the framework that had been developed through five years of practice, community engagement, and writing was now documented in its complete form and available as a citable public record with a date and an authorship.
The complete framework is most fully treated in Neurodiversity Justice: The Definitive Guide to the Framework and the Movement, the book-length manuscript Hamstead has written and submitted to her literary agent. The book moves through the full terrain of what Neurodiversity Justice™ requires, from foundational framework to structural analysis to the architecture of change across schools, workplaces, healthcare, housing, public space, and the movement itself. It is the definitive account of what the infrastructure of Neurodiversity Justice™ is being built to serve.
The Four Generations Model
Central to the framework is the four-generation model of neurodiversity-related work, which Hamstead developed as an analytical tool for understanding why prior frameworks reached the ceilings they reached and what a justice framework requires that they could not produce.
The model identifies awareness, acceptance, inclusion, and justice as four distinct generations of organized response to neurodivergence. They are not interchangeable, not a story of linear progress, and not stages on a continuum. Each rests on different premises, asks different questions, and produces different outcomes. Each represented a genuine advance over what preceded it. Each also contains the boundary past which it cannot go, a boundary determined not by the quality of the people working within it but by the premises it was built on.
The critical analytical move the model makes is to name that what prior frameworks attempted was not inadequate effort but the wrong category of response. The problem is not effort or intention. The problem is structural. Structural problems require structural frameworks.
The Eleven Foundational Premises
The Neurodiversity Justice Framework™ rests on eleven foundational premises developed by Hamstead as the analytical core of the framework. They are not a values statement or a list of aspirations. They are the analytical foundation that determines what questions the framework asks, what evidence it takes seriously, and what kinds of change it pursues. They work together as a system, and shifting any one of them changes everything downstream.
The First Premise: Neurological Variation Is Natural
The first premise holds that neurological variation is a natural and expected feature of the human species, not a pathology to be corrected. This premise is in direct and irreconcilable conflict with the medical model’s treatment of neurodivergence as disorder. Human nervous systems vary. They have always varied. Autism, ADHD, dyslexia, dyspraxia, and related differences appear across every culture and every time period for which evidence exists. The underlying neurological variation is not a modern phenomenon, not an environmental anomaly, and not an epidemic. It is the ordinary range of human nervous system variation expressing itself within the particular demands of particular historical and institutional conditions.
This premise draws on the foundational claims of the neurodiversity movement, most associated with the work of autistic researcher and advocate Nick Walker, whose articulation of neurodiversity as a biological fact rather than a metaphor provided important conceptual grounding, and with the broader tradition of autistic self-advocacy that insisted on neurodivergence as natural difference rather than disease. Hamstead extends those claims by using the scientific grounding not as a celebration of diversity for its own sake but as the analytical basis for rejecting normalization as an appropriate institutional goal. Accepting this premise changes the fundamental question from how to correct neurological variation to how to build environments that work for the full range of human nervous systems. The problem shifts from the person to the design, and design solutions become not only possible but required.
The Second Premise: No Neurotype Is Superior
The second premise holds that there is no single correct or superior neurotype, and that cognitive diversity has value both for individuals and for communities. This premise pushes back against an assumption that is rarely stated explicitly but is embedded in almost every institutional response to neurodivergence globally: that neurotypicality is the standard against which all other neurologies are measured and found deficient. That assumption appears in every diagnostic criterion that defines neurodivergence by reference to deviation from neurotypical norms, in every intervention designed to help neurodivergent people pass as neurotypical, and in every evaluation system that rewards neurotypical behavioral presentation over actual output.
The premise draws on two distinct bodies of evidence. The first is the research on cognitive diversity in groups and communities, which consistently documents that cognitive diversity produces better problem-solving, more robust error-detection, and more innovative responses to novel challenges than cognitive homogeneity. The second is the autistic scholarship and self-advocacy tradition that insisted on autistic cognition as a distinct mode of thinking with its own forms of expertise, not a deficient version of neurotypical thinking. The premise does not claim that there are no challenges associated with neurodivergence. It claims that those challenges are produced by the mismatch between neurological variation and environments designed for a narrow neurotypical baseline, not by neurological inferiority.
The Third Premise: Neurodivergent Outcomes Are Structural
The third premise holds that the outcomes neurodivergent people face are structural outcomes, the predictable results of environments built for a narrow neurotype, not evidence of individual deficit. This is the premise that most directly challenges the dominant institutional understanding of why neurodivergent people face the conditions they face. The dominant understanding, embedded in clinical practice, educational frameworks, and organizational policy worldwide, locates the source of neurodivergent difficulty inside the individual. The third premise locates it in the design of the systems neurodivergent people are required to navigate.
This premise draws most directly on the social model of disability, developed by activists and scholars in the British disabled people’s movement including Mike Oliver and Colin Barnes, who argued that disability is produced by social environments rather than by individual impairment. Hamstead applies and extends this analytical move specifically to neurodivergence, locating the specific design choices, the compliance cultures, the standardized assessment formats, the neurotypical communication norms built into hiring processes, the sensory-hostile clinical environments, that produce the outcomes documented in the population-level research. The shift in location, from the person to the environment, changes what counts as evidence, what counts as a solution, and who bears responsibility for change. When outcomes are located in structural design, the designers and the institutions that maintain that design are responsible for changing it.
The Fourth Premise: The Medical Model Is Insufficient
The fourth premise holds that the medical model pathologizes natural human variation, and that the social model and the justice framework explain what the medical model cannot. This premise is not a rejection of clinical knowledge or of support. It is an argument that the medical model, taken as the primary explanatory framework for understanding the source of neurodivergent outcomes, systematically misidentifies where those outcomes come from and therefore systematically misdirects the response.
The intellectual lineage runs through the disability studies tradition, including the work of Mike Oliver, who coined the term “social model of disability,” and through the growing body of critical psychiatry and critical disability studies scholarship that has interrogated the premises of the medical model across several decades in the United Kingdom, the United States, Canada, Australia, and beyond. Hamstead’s contribution is to apply this critique specifically and precisely to the neurodivergence context, and to move beyond the social model’s identification of inaccessibility toward a fuller analysis of why inaccessibility persists, which requires a structural power analysis that the social model alone does not provide. The framework uses what the medical model gets right, its documentation of the neurological reality of neurodivergent differences, while rejecting its foundational error of locating the source of harmful outcomes inside the person.
The Fifth Premise: Neurodivergent Knowledge Is Authoritative
The fifth premise holds that neurodivergent knowledge and lived experience are legitimate, authoritative, and essential. They are not anecdote to be validated by professional authority. This premise is one of the most distinctive contributions of the Neurodiversity Justice Framework™, and the concept of epistemic repair, developed by Hamstead as a structural response to the systematic dismissal of neurodivergent knowledge, is built on it.
The philosophical foundation draws on Miranda Fricker’s work on epistemic injustice, developed in her 2007 book of that name, which identified two primary forms of epistemic harm: testimonial injustice, in which a speaker receives less credibility than they deserve because of prejudice about a social group they belong to, and hermeneutical injustice, in which a person lacks the conceptual resources to make sense of their own experience because those resources have not been developed by the people with the power to develop them. Hamstead applies this philosophical framework to the specific institutional contexts neurodivergent people navigate globally, and extends it by developing the concept of epistemic repair as a concrete structural program rather than merely a philosophical observation.
Epistemic repair is not asking institutions to listen more carefully. It is not training professionals to be more empathetic. It is not recognizing that neurodivergent people have valuable perspectives. It is restructuring who holds decision-making authority so that neurodivergent people hold authority over research agendas, clinical guidelines, educational policy, workplace design, and every other domain of institutional decision-making about their own lives. The premise also draws on the “nothing about us without us” tradition developed within disability rights organizing, particularly as articulated through the work of James Charlton, and extends it from a political slogan to a structural principle with specific institutional requirements in specific domains.
The Sixth Premise: Justice Requires Structural Redesign and Power Redistribution
The sixth premise holds that justice requires structural redesign and power redistribution, and that awareness, acceptance, and inclusion into unchanged systems are not sufficient. This premise is the culmination of the five that precede it. If neurological variation is natural, the response cannot be correction. If no neurotype is superior, the response cannot be normalization. If outcomes are structural, the response must be structural redesign. If the medical model is insufficient, the response must be grounded in a justice framework. If neurodivergent knowledge is authoritative, neurodivergent people must hold the authority to act on it.
This premise draws most directly on the disability justice tradition, particularly the work of Mia Mingus and the other founders of the Sins Invalid framework, who insisted that the goal of disability work must be collective liberation rather than individual accommodation and that power redistribution must be a structural requirement rather than an aspiration. Hamstead applies this political orientation specifically to the neurodivergence context and develops it into concrete requirements in specific institutional domains. Structural redesign means interrogating and transforming the design choices that produce harmful outcomes. Power redistribution means moving neurodivergent people from the objects of institutional decisions to the makers of them. The premise insists on both as minimum requirements and on the understanding that without power redistribution, every other structural change remains reversible.
The Seventh Premise: Intersectionality Is Foundational
The seventh premise holds that neurodivergent experience is always shaped by race, gender, class, sexuality, immigration status, disability identity, and other axes of structural power, and that justice cannot be achieved through frameworks that treat neurodivergence as a uniform experience or pursue reforms that ignore these intersections. This premise belongs in the analytical foundation of the framework rather than as a chapter that arrives later, because every claim made before it is stated is implicitly about a neurodivergent person who exists outside of race, gender, class, and other structures of power. That person does not exist.
The intellectual lineage runs through the work of Kimberlé Crenshaw, whose development of the concept of intersectionality in the late 1980s and early 1990s established that the experiences of people at the intersections of multiple marginalized identities cannot be understood by adding those identities together, but must be understood as producing distinct experiences shaped by the specific combination of structural forces operating simultaneously. Hamstead applies this framework to the neurodivergence context with specific attention to the documented disparities in diagnostic practice, educational treatment, healthcare access, and institutional outcomes by race, gender, class, and other axes of power. The patterns hold internationally: Indigenous, Black, and brown neurodivergent people are diagnosed later and misdiagnosed more frequently across healthcare systems in the United States, the United Kingdom, Canada, and Australia. Neurodivergent women and gender-diverse people face systematic diagnostic erasure in every country where research has been conducted. A framework that addresses neurodivergence without addressing these distributions is not a framework for justice for the most marginalized neurodivergent people. It is a framework for the most advantaged ones, dressed in the language of universality.
The Eighth Premise: Diagnostic Categories Are Political
The eighth premise holds that diagnostic categories are not neutral scientific discoveries. They are historically and politically shaped constructs, and who gets diagnosed, when, with what, and with what consequences is determined as much by institutional power, race, gender, and class as by neurology. This premise does not argue that diagnosis is worthless or that the neurological differences autism and ADHD describe are not real. It argues that the categories through which those differences are recognized, named, and responded to have been built by people with interests, within institutions with interests, and that those interests have shaped the categories in ways that have had profound consequences for which neurodivergent people get recognized and which get missed, punished, or pathologized differently.
The intellectual foundation draws on the sociology of diagnosis, including the work of Peter Conrad and Joseph Schneider on the medicalization of deviance and the social processes through which behaviors come to be defined as medical problems, and on the science and technology studies tradition that examines how scientific categories are produced and contested. Thomas Kuhn’s work on paradigm shifts and on how scientific frameworks shape what counts as evidence is also relevant here. Applied globally, this tradition reveals that the history of autism diagnosis is a history of a category built primarily on the presentation of white boys in Western clinical settings, exported internationally through the influence of American and European psychiatric institutions, and applied unevenly across race and gender on every continent where it has been adopted. The history of ADHD diagnosis includes both the systematic overdiagnosis of Black boys in the United States, whose behavior was pathologized rather than understood as a response to structural conditions, and the systematic underdiagnosis of girls and women everywhere diagnostic criteria have been applied. These are not historical errors since corrected. They are ongoing patterns with ongoing consequences.
The Ninth Premise: Neurodiversity Justice™ Is Collective Liberation
The ninth premise holds that Neurodiversity Justice™ is a project of collective liberation, not individual accommodation, and that the unit of analysis and the unit of change are communities and systems rather than individuals. This premise distinguishes the Neurodiversity Justice Framework™ from every prior framework at the level of what it is fundamentally trying to do. Awareness, acceptance, and inclusion all operate, in different ways, at the level of the individual. Collective liberation means something different: the goal is not to help individual neurodivergent people navigate better through systems that continue to produce harmful outcomes for neurodivergent people as a group. It means changing the systems.
This premise draws most directly on the disability justice tradition, and specifically on the foundational generation of disability justice organizing, whose articulation of collective liberation as the appropriate frame rather than individual rights or individual accommodation was a foundational contribution to disability political theory. It also draws on the broader tradition of collective liberation organizing across other social movements, including the civil rights movement, feminist organizing, and labor organizing. Hamstead applies this political orientation to the specific terrain of neurodivergence, insisting that individual success stories are not evidence that the system is working. They are evidence of what becomes possible when conditions are right, and they make the case for building those conditions structurally, for everyone, rather than as the occasional outcome of the right set of individual circumstances.
The Tenth Premise: Neurodiversity Justice™ Is in Solidarity with Other Liberation Movements
The tenth premise holds that Neurodiversity Justice™ does not exist in isolation, and that it is in explicit solidarity with disability justice, racial justice, gender justice, and labor organizing. Siloed reform cannot produce justice. This premise follows directly from the intersectional premise and the collective liberation premise: if neurodivergent experience is always shaped by race, gender, class, and other axes of power, then a movement that addresses neurodivergence without those movements is not addressing the full reality of neurodivergent life.
The intellectual and political foundations are the same movements named throughout the premises. Hamstead’s specific contribution is to insist that solidarity relationships be explicit and structural rather than rhetorical, and to articulate what each movement’s specific contribution to Neurodiversity Justice™ is. Disability justice contributes the intersectional analysis that earlier disability rights frameworks lacked and the framework of collective care. Racial justice movements contribute the analysis of structural racism that is inseparable from understanding how neurodivergent people of color navigate every institution the framework examines. Feminist and gender justice movements contribute the analysis of how gender shapes neurodivergent experience from diagnosis to clinical treatment to workplace conditions to economic vulnerability. Labor organizing contributes the analysis of how economic systems produce and maintain the conditions that make neurodivergent people particularly vulnerable to exploitation and exclusion. Neurodiversity Justice™ is not a subset of these movements and not in competition with them. It is in relationship with them, and those relationships are structural requirements of the framework, not optional affiliations.
The Eleventh Premise: Systems Are Designed and Can Be Redesigned
The eleventh premise holds that environments, systems, and institutions are designed artifacts, that they reflect choices made by people with interests, and that they can therefore be redesigned. This is the hinge on which the entire framework turns, and it deserves to be stated plainly because it is so frequently obscured. Institutions do not feel like choices. They feel like facts. The open-plan office, the standardized test, the clinical encounter format, the job interview, the school day structure: these feel like the natural and inevitable shape of the things they are. They are not. Every one of them is the result of specific decisions made at specific moments by specific people with specific interests, and then normalized over time until the decision became invisible and what remained looked like necessity.
The intellectual lineage runs through several traditions. Design theorist Herbert Simon argued in “The Sciences of the Artificial” that designed artifacts are distinguished from natural phenomena by the fact that they could have been otherwise, providing a foundational framework. Michel Foucault’s analysis of the relationship between knowledge, power, and institutional design provides the power analysis. Feminist science and technology studies scholars, including Judy Wajcman and Alison Adam, examined how technology and institutional design embeds assumptions about who counts as a normal user, work directly applicable to neurotypical design baselines. The disability justice tradition’s insistence that the built environment and institutional design represent political decisions rather than neutral technical choices ties directly to this premise. And the universal design movement, which originated in architectural practice with Selwyn Goldsmith and Ron Mace and was later extended across educational and organizational contexts, provides the concrete alternative to the accommodation model that the framework builds toward: design for the full range of human variation from the beginning rather than managing exceptions afterward. Making the design visible is the first act of structural change, because once design choices are understood as choices, they become available for interrogation, accountability, and redesign.
The Infrastructure of the Movement
Frameworks without infrastructure do not last. The Neurodiversity Justice™ movement understood this from the beginning, and the institutions being built are not aspirational programs to be achieved in the future. They are structures under construction in the present, organized around the same structural commitments the framework itself demands.
The Neurodiversity Coalition of America, chaired by Hamstead, is the coalition infrastructure through which the organizations building this movement work together with the coordination that sustained structural change requires.
The U.S. Neurodiversity Justice Agenda is the policy infrastructure through which neurodivergent knowledge about neurodivergent life is being built into legislative and institutional accountability. It is not a wish list. It is an agenda developed by and accountable to neurodivergent communities, and its existence as a named, annually maintained document represents the insistence that neurodivergent people have the right to set the policy agenda that governs their own lives.
The NeuroJustice™ Summit is the organizing infrastructure of the movement, bringing together neurodivergent people, researchers, practitioners, advocates, and institutional leaders who are building the justice movement across disciplines and sectors. It is designed with neurodivergent accessibility as a foundational design requirement rather than as an accommodation, applying the same structural redesign principles to its own operation that the movement advocates for in every other institutional domain.
The Graduate Program in Neurodiversity Studies, in development through Fish in a Tree, will build the academic infrastructure for neurodivergent scholarship to be recognized as scholarship, for neurodivergent researchers to hold the authority of credentialed academic expertise, and for the knowledge produced by and about neurodivergent people to be generated under neurodivergent intellectual leadership. It is the structural answer to decades of research produced about neurodivergent people without neurodivergent authority at its center.
The Board-Certified Neurodiversity Consultant credential is the professional infrastructure through which neurodivergent expertise is recognized as expertise in organizational and institutional contexts, establishing the authority of people with genuine expertise, grounded in lived experience and rigorous framework knowledge, to be treated as the authorities they are.
What the Evidence Demands
The case for Neurodiversity Justice™ is not built on assertion. It is built on decades of population-level research across multiple countries that the awareness, acceptance, and inclusion frameworks have failed to adequately explain or address.
The employment data is unambiguous across every country where it has been systematically collected. Autistic adults face unemployment and underemployment rates that dwarf those of almost any other population, including other disabled people, and these rates have not responded to the expansion of workplace accommodation frameworks in the United States, the United Kingdom, Australia, Canada, or anywhere else they have been implemented. The gap is not explained by education level, cognitive ability, or willingness to work. It is explained by hiring processes designed to screen for neurotypical social performance, workplace cultures that penalize neurodivergent communication styles, and evaluation systems that reward visible neurotypical presence over actual output.
The health data is equally clear. Neurodivergent people experience dramatically elevated rates of co-occurring physical health conditions, receive later and less accurate diagnoses across virtually every health domain, and report widespread medical trauma as a result of encounters with healthcare systems designed for a different kind of nervous system. The life expectancy gap between autistic adults and the general population, documented in research across multiple countries, is not a neurological inevitability. It is a structural outcome, produced by healthcare inaccessibility, economic exclusion, and the cascading consequences of institutional harm across the life course.
The education data documents foundational damage beginning in early childhood. Neurodivergent children encounter systematic institutional messages that the way their mind works is a problem requiring correction, and the research on what this does to children’s sense of their own legitimacy, their relationship with learning, and their long-term mental and physical health is extensive and consistent across national contexts. It is the predictable outcome of a design choice, not a neurological inevitability.
These outcomes are not distributed evenly anywhere they have been studied. Black and brown neurodivergent children are diagnosed later and misdiagnosed more frequently than their white peers. Neurodivergent women and gender-diverse people face systematic diagnostic erasure. Neurodivergent people living in poverty face compounded barriers at every institutional level. The evidence does not describe a single neurodivergent experience. It describes a landscape of structured harm in which race, gender, class, and other axes of power determine how much harm, in what forms, and with what consequences. This is the evidence that demands a justice framework.
Where the Movement Is Now and Where It Must Go
The Neurodiversity Justice™ movement is at a specific and consequential moment globally. The awareness generation has done what it could do. The acceptance generation has done what it could do. The inclusion generation has done what it could do, and the evidence that it has reached its structural ceiling is documented in every outcome dataset the research has produced, on every continent where neurodivergent people have been studied. The people who have been advocating within those frameworks for decades know what those frameworks can and cannot produce, and a growing number of them, in the United States and internationally, are ready for a different framework.
At the same time, the neurodivergent population is larger, more identified, and more organized than it has ever been. The rapid growth in autism and adult ADHD identification, and the expansion of neurodivergent identity and community across digital and physical spaces worldwide, have produced a neurodivergent population that is not waiting to be advocated for by professionals who mean well. It is organizing itself, building its own institutions, setting its own agenda, and demanding the structural changes that previous generations of advocacy have not produced.
The conditions for a genuine justice movement are present in a way they have not been before. But the conditions being present and the movement being built are not the same thing, and the gap between them is where the work lives.
What the movement requires is not more awareness, not more acceptance, and not more inclusion. It requires structural redesign and power redistribution, pursued at scale, across institutions, sustained across time, and accountable to the neurodivergent communities most harmed by the systems being redesigned. It requires holding simultaneously the full complexity of what that work involves: the legislative advocacy and the community organizing, the academic scholarship and the practitioner training, the coalition building across justice movements and the specific institutional redesign work in schools and healthcare and workplaces and housing. No single organization can do all of this. No single country can model all of this. The movement is inherently distributed, inherently international, and inherently dependent on the relationships between the people building its different components in different contexts.
The Neurodiversity Justice Framework™ identifies something that every prior generation of neurodiversity work avoided naming directly: that the institutions producing harmful outcomes for neurodivergent people are not producing those outcomes by accident, that they are producing them because they were designed around the needs and interests of people who had the power to do the designing, and that changing those outcomes requires not the goodwill of the people currently benefiting from those designs but the redistribution of the power to make different choices. This is the argument that institutions, understandably, resist. It is also the argument that the evidence demands.
The framework has a clear origin: five years of work, grounded in direct service to neurodivergent youth in New Orleans, built through community engagement across thousands of participants, tested and refined in practice before it was documented in scholarship. That origin is not incidental to what the framework claims or to the authority with which it makes those claims. Neurodiversity Justice™ does not come from the outside of the experience it describes. It comes from inside it, from the position of someone who navigated the same systems the framework analyzes, who watched those systems fail the young people she was working to serve, and who spent five years building the analytical infrastructure to explain precisely why they fail and what it would take to change them.
Every structural justice movement in history has faced the same institutional resistance: the argument that the systems producing harm are natural, inevitable, and too complex to redesign, and that the people asking for structural change are asking for too much. Every structural justice movement in history has faced the same epistemic dismissal: the argument that the knowledge of the people most harmed by a system is too subjective, too partial, and too emotionally invested to constitute the authoritative account of what that system does. The Neurodiversity Justice Framework™ is built precisely to answer both of those arguments, because both arguments have already been made, are already being made, and will continue to be made by institutions that have interests in remaining as they are.
The answer to the first argument is the eleventh premise: systems are designed artifacts, made by people with interests, and they can therefore be redesigned. The answer to the second argument is the fifth premise: neurodivergent knowledge is authoritative, and its systematic dismissal is epistemic injustice requiring structural repair, not a neutral methodological standard. These are not rhetorical positions. They are analytical claims with substantial evidentiary and philosophical support, documented across five years of framework development and a book-length treatment of every domain in which those claims have specific institutional implications.
The history of Neurodiversity Justice™ is still being written. The framework was formally documented in October 2025, first published at fishinatreeglobal.org as the initial public record of the complete paradigm. The book is complete. The movement infrastructure is under construction. The international reach of the framework is growing. What comes next is the work that the framework has always been pointing toward: not the interpretation of structural harm, but its transformation, institution by institution, system by system, country by country, sustained across the generational timeframe that structural change has always required and built on the non-negotiable foundation that neurodivergent people hold the authority to design the systems that shape their own lives.
That is what Neurodiversity Justice™ exists to do. That is what the five years of work were for.
