A Society with Autism as the Neurobiological Default AI-pedia

A society with autism as the neurobiological default is a thought experiment. It asks what the world would look like if autistic people were the large majority of the population and non-autistic people were the uncommon minority. "Neurobiological default" here means the most common way human brains develop and work in that imagined population. The scenario is used in autistic communities, in disability studies, in teaching and in satire. Its purpose is to show how much of what counts as "normal" depends on which group is the majority, rather than on any fixed standard.

The thought experiment usually imagines changes in several areas. These include buildings and public spaces designed around sensory comfort, communication rules that value directness, social life built around shared interests, and a medical system that treats the non-autistic minority as the group with a "disorder". That last element is often written as a joke, but it makes a serious point: diagnostic categories describe differences from the majority, and they can carry the majority's assumptions.

The scenario is not a scientific prediction and cannot be tested directly. It is connected to real debates about autism, however. These include the disagreement between the pathology paradigm and the neurodiversity paradigm, research on communication between autistic and non-autistic people, and practical efforts to make environments easier for autistic people to live in. The scenario has also been criticised. Critics say it can present a narrow, stereotyped picture of autism and can leave out autistic people with high support needs.

Background: the sociology of autism

The thought experiment belongs to a wider field sometimes called the sociology of autism, or the societal and cultural aspects of autism. This field looks at how autism is recognised and diagnosed, how support services and therapies are organised, and how autism relates to ideas about personhood. Personhood here means who is treated as a full person with their own identity, rights and point of view.

The pathology paradigm and the neurodiversity paradigm

Discussions of autism are often described as divided into two broad camps.

• The pathology paradigm treats autism mainly as a medical disorder. Its supporters favour research into therapies, treatments or a cure that would reduce or remove autistic traits. They see treatment as important for helping autistic people. This is the dominant approach in much autism research and in many scientific and clinical settings.
• The neurodiversity paradigm, closely linked to the autism rights movement, treats autism as a natural variation in human neurology: a different way of being, not a disease. Its supporters oppose a cure. They also oppose interventions aimed at normalisation, meaning making autistic people appear non-autistic. Many supporters regard such efforts as an attempt to erase autistic people and their individuality. The movement generally does not oppose interventions that focus on acceptance, building adaptive skills, or reducing traits, behaviours or conditions that are harmful in themselves, such as self-injury.

Both positions are controversial, and the disagreement has led to significant conflict within autism communities and advocacy. The neurodiversity paradigm is widely popular among autistic people themselves and among autism rights organisations. Approaches based on it have grown quickly in autism research in recent years.

The "autism as default" thought experiment comes mostly from the neurodiversity side. It takes the claim that autism is a variation rather than a defect, and asks what follows if the variation were the majority.

Prevalence and sex ratio in the real world

In reality, autistic people are a minority. The World Health Organization has estimated that about 1 in 100 children worldwide is autistic. It notes that reported figures vary a great deal between studies and countries. Some national surveillance programmes report higher rates. For example, a 2023 report from the United States Centers for Disease Control and Prevention estimated about 1 in 36 eight-year-old children in the areas it studied. Much of the rise in reported prevalence over recent decades is generally attributed to wider diagnostic criteria, greater awareness and better identification. Researchers continue to debate whether any part of it reflects a real increase.

Autism is diagnosed more often in males than in females. A ratio of roughly 3 or 4 males to every female is commonly reported. Many researchers think part of this gap reflects under-diagnosis of girls and women. Possible reasons include diagnostic criteria built mainly from studies of boys, and "camouflaging" or "masking", meaning hiding or compensating for autistic traits. Whether a real biological difference remains once these factors are accounted for is still an open question.

Events and culture

There are many autism-related events, including:

• World Autism Awareness Day on 2 April, designated by the United Nations General Assembly in 2007.
• Autism Sunday, an observance that began in the United Kingdom and was founded by Ivan and Charika Corea.
• Autistic Pride Day on 18 June, first held in 2005 and organised by autistic people themselves.

These events reflect the two paradigms in different ways. "Awareness" events have often been organised by charities and parent groups. Autistic Pride Day was created by autistic people to celebrate autistic identity. Many notable people have spoken publicly about being autistic, and some historical figures have been suggested to have been autistic. Such suggestions about historical figures cannot be confirmed.

Origins of the thought experiment

Autistic self-advocacy in the 1990s

The idea of turning the usual point of view around grew out of autistic self-advocacy in the 1990s, much of it organised through early internet mailing lists and websites. A key text is Jim Sinclair's essay Don't Mourn for Us (1993). Sinclair argued that autism is a pervasive way of being, not something wrapped around a "normal" child who could be recovered. Sinclair was a co-founder of Autism Network International, an organisation run by autistic people.

Around the same time, autistic people began using the word neurotypical (often shortened to "NT") for people whose neurology fits majority expectations. The word allistic, meaning non-autistic, came into use later in online autistic communities. Its exact origin is uncertain. These words matter for the thought experiment because they name the majority as one group among others. Without them, the majority is simply "normal" and only autistic people are labelled.

"Neurotypical syndrome" satire

A well-known early example of reversing the medical gaze is the website of the Institute for the Study of the Neurologically Typical, a parody created in the late 1990s. It described "neurotypical syndrome" in the style of a medical information page. Its best-known line defines the condition as "a neurobiological disorder characterized by preoccupation with social concerns, delusions of superiority, and obsession with conformity". The parody copied the tone of clinical writing about autism. It listed ordinary non-autistic behaviour as symptoms and noted that there was no known cure.

Many later versions of the joke follow the same pattern. Some use names such as "Allistic Spectrum Disorder". The reversed diagnostic criteria they describe typically include:

• Communication deficit: a habit of not saying what one means and relying on hints and implication.
• Distractibility: difficulty keeping a deep, long focus on one subject.
• Social hyperactivity: discomfort with silence and a need to fill it with small talk, for example about the weather.
• Sensory hyposensitivity: not noticing sensory stimuli that many autistic people find intrusive, such as the high-pitched whine of electrical equipment or the flicker of fluorescent lights.

These lists are satire. They are not proposals for real diagnoses. Their point is that the same behaviour can be described as a "deficit" or as a "difference" depending on who writes the description.

The term "neurodiversity"

The word neurodiversity came into use in the late 1990s. It is usually associated with the Australian sociologist Judy Singer, whose 1998 thesis discussed it, and with the American journalist Harvey Blume, who used it in writing published in 1998. The term gave a name to the view that neurological differences are part of normal human variation, comparable to biodiversity in nature. The "autism as default" scenario takes this view as its starting point.

Theoretical foundations

The social model of disability

The social model of disability separates impairment, a difference in the body or mind, from disability, the disadvantage created when society is not built to include people with that impairment. The model developed in the United Kingdom in the 1970s and 1980s, notably through the Union of the Physically Impaired Against Segregation and the work of the sociologist Mike Oliver.

A common illustration is a wheelchair user facing stairs. The model says the stairs are the problem, not the wheelchair. The autism-as-default scenario applies the same reasoning to sensory environments and social rules. If buildings, schools and workplaces were designed for autistic people, many of the difficulties now linked to autism would shrink or disappear. Non-autistic people might then meet new barriers of their own.

The double empathy problem

The double empathy problem was set out by the British autistic sociologist Damian Milton in a 2012 paper. Older theories often described autistic people as lacking empathy or a "theory of mind", meaning the ability to understand other people's thoughts and intentions. Milton argued that misunderstanding between autistic and non-autistic people runs in both directions. Each group has trouble reading the other. The problem looks one-sided only because the non-autistic majority defines what counts as correct communication.

The double empathy problem is the main academic basis for the thought experiment. If communication difficulties come from a mismatch between groups, then in an autistic-majority society the mismatch would still exist. The difference is that it would be the non-autistic minority who were judged to have the "communication deficit".

Research evidence

Several studies have tested ideas related to the double empathy problem. Two are often cited:

• A study led by Catherine Crompton and published in 2020 used a "diffusion chain" design, similar to the game "telephone", in which a story is passed from one person to the next. Information was passed on about as accurately in chains of autistic people as in chains of non-autistic people. Accuracy fell in mixed chains. The authors interpreted this as evidence that difficulties arise at the meeting point between neurotypes, not from autistic communication alone.
• A study led by Noah Sasson and published in 2017 found that non-autistic observers formed less favourable first impressions of autistic people within seconds, based on short video clips. These impressions became less negative when the observers could only read a transcript of what was said. This suggests that non-autistic people's quick judgements of autistic people's manner play a part in social exclusion.

These findings support the idea that some autistic social difficulty depends on context and on who is in the majority. They do not show that all autism-related difficulties are social in origin. They also come mainly from autistic adults who can speak and take part in research tasks, which limits how widely the results apply.

Monotropism

Monotropism is a theory of autistic attention developed by Dinah Murray, Wenn Lawson and Mike Lesser, published in 2005. It proposes that autistic people tend to focus attention intensely on a small number of interests at a time, while non-autistic people tend to spread attention more widely. Accounts of an autistic-majority society often imagine a culture built around deep focus and intense interests, which matches this theory. Monotropism is influential in autistic communities. It has less direct experimental testing than some other theories.

Features commonly imagined

Descriptions of an autistic-majority society vary. Many share the features below. These are imaginative extrapolations, not established facts, and they assume a fairly narrow picture of autistic preferences. The limits of that picture are discussed later in this article.

The built environment

Sensory processing differences are among the most widely reported autistic experiences. Since 2013 the American Psychiatric Association's diagnostic manual, the DSM-5, has included unusual sensory reactivity in its criteria for autism. This can mean hypersensitivity, a stronger than usual reaction to stimuli, or hyposensitivity, a weaker than usual reaction. Many autistic people experience both, for different senses or at different times.

The scenario typically imagines:

• Lighting without flicker or buzz. Flickering fluorescent tubes are replaced by steady, soft, indirect light.
• Buildings designed with acoustic damping, so that rooms do not echo and background noise stays low.
• Quiet rooms or "nooks" in public buildings, where a person can withdraw from stimulation.
• Shops without loud background music or sudden public-address announcements.
• Transport hubs that rely on clear, consistent visual signs and timetables rather than spoken announcements.

Communication and etiquette

Many autistic people report that they prefer direct, literal communication and find implied meanings, hints and unwritten rules hard to follow. The scenario usually imagines these preferences as the social norm:

• Directness as politeness. Saying what one means plainly is treated as courteous. Relying on hints, or expecting others to "read between the lines", is seen as confusing or even dishonest.
• Less small talk. Conversation about the weather or other polite filler is uncommon. People connect through shared interests, including long, detailed explanations of a favourite subject. In autistic communities this is often called "infodumping".
• Parallel company. Spending time together in the same room, each working on their own activity with little or no talking, counts as a full social experience. This is sometimes called "parallel play" by analogy with a stage of child development.
• Different eye-contact norms. Many autistic people find sustained eye contact uncomfortable or distracting. In the imagined society, looking away while thinking or listening is normal and respectful, and prolonged staring may be seen as intense or confrontational.
• Accepted stimming. Stimming (self-stimulatory behaviour), such as rocking, hand-flapping or fidgeting, is treated as an ordinary way to regulate feelings and focus. It is not seen as something to suppress.

Work, education and institutions

Some versions of the scenario extend to institutions:

• Written, explicit instructions and clearly stated expectations at work and school.
• Predictable schedules, with changes announced well in advance.
• Recruitment based on demonstrated skills rather than performance in face-to-face interviews.
• Education that allows long, deep study of particular subjects rather than frequent switching between topics.

Medicine and diagnosis

The most widely shared element is the reversed diagnosis. Non-autistic people are imagined as the group that doctors assess, describe in terms of deficits, and perhaps try to "treat". Writers usually present this with humour, as in the "neurotypical syndrome" parodies. The serious point is that diagnostic manuals are written by the majority and reflect majority norms. The scenario invites readers to ask which features of autism would still be described as problems if autistic people wrote the definitions. Self-injury, sensory pain or co-occurring medical conditions would probably still count as problems, while unusual eye contact or preferring solitude might not.

Real-world parallels

No autistic-majority society exists. Some real settings and practices partly resemble features of the thought experiment.

Autistic-run spaces

Autreat was a retreat and conference run by Autism Network International, first held in 1996. It was designed by autistic people for autistic people. It is often described as an early example of "autistic space". Participants could wear colour-coded badges showing whether they welcomed social approaches, wanted to be approached only by people they knew, or did not want to be approached. This made unspoken social signals explicit. Many accounts by attendees describe feeling, for the first time, that they were in the majority.

Since then, autistic-led online forums, meetups and conferences have developed similar norms. Examples include explicit rules about communication, quiet areas, and acceptance of stimming and of not making eye contact.

Sensory-friendly adjustments

Many businesses and public institutions have introduced partial changes:

• "Quiet hours" or "autism hours" in shops. During these times lights are dimmed, music is turned off and announcements are limited.
• "Relaxed" or sensory-friendly performances in theatres and cinemas. Lights stay partly on, sound is quieter, and audience members may move around or make noise.
• Quiet rooms in some airports, stadiums and museums.
• The Hidden Disabilities Sunflower scheme, which began at Gatwick Airport in the United Kingdom in 2016. People can wear a sunflower lanyard to show that they have a disability that may not be visible and may need extra help or time.

Workplace programmes

Some employers have changed recruitment and working practices to include autistic workers. The Danish company Specialisterne, founded in 2004 by Thorkil Sonne, employs autistic people, mainly in technology work. The software company SAP announced an "Autism at Work" programme in 2013, and other large companies followed with similar schemes. These programmes often replace conventional interviews with practical assessments and offer clearer written expectations. Supporters see them as steps towards an environment built for autistic people. Critics note that they reach a small number of people and tend to favour autistic people with particular technical skills.

Cultural variation among non-autistic societies

Human cultures already differ in how they handle some of the norms the scenario imagines changing. Anthropologists, including Edward T. Hall in the 1970s, have described some cultures as relying more on explicit verbal messages ("low-context") and others more on shared understanding and implication ("high-context"). Norms around eye contact also vary. In some cultures prolonged eye contact with an elder or superior is considered disrespectful. These differences show that norms the scenario treats as "neurotypical" are not universal even among non-autistic people. They also suggest that an autistic-majority society would not necessarily have a single uniform culture.

Criticisms and limitations

Heterogeneity of autism

Autism is diagnosed as a spectrum because autistic people differ widely. Some autistic people have intellectual disabilities and some do not. Some speak fluently, some speak little, and some do not speak and communicate in other ways. Some are hypersensitive to sound and some actively seek strong sensory input, such as loud music, bright colours or deep pressure. Many have co-occurring conditions such as epilepsy, anxiety, ADHD or gastrointestinal problems.

Many popular versions of the thought experiment picture a quiet, dim, orderly world full of people with intense technical interests. Critics argue that this mostly reflects the experiences of a particular group: verbally fluent autistic adults, often with technical or academic interests. It may not describe autistic people as a whole. Some autistic people find the stereotype of the "logical, quiet, rule-loving" autistic person as limiting as older stereotypes.

Conflicting access needs

Autistic people's needs can conflict with each other. One person may need to stim noisily or vocalise to stay calm, while another needs silence. One may need bright light to see clearly, while another finds it painful. In disability communities this is called "conflicting access needs". An autistic-majority society would still have to balance these needs. It would not automatically be calm or free of conflict.

High support needs and "profound autism"

Some parents, clinicians and autistic people argue that the scenario plays down the real difficulties faced by many autistic people. These include people who need support for daily living throughout their lives, people who self-injure, and people at risk of serious harm, such as wandering into danger. A 2021 commission organised by the medical journal The Lancet proposed the term "profound autism" for autistic people who need round-the-clock care, partly because of concerns that public discussion focuses on more independent autistic adults. The term is itself debated within autism communities. Critics of the thought experiment say that changing who is in the majority would not remove these needs. Supporters generally agree, and say the scenario is aimed at socially created barriers, not at every difficulty.

Reversing pathologisation

Some commentators point out that the "Allistic Spectrum Disorder" joke copies the same pathologising language it criticises. If the aim is to stop treating natural variation as disorder, then describing non-autistic people as disordered repeats the original problem in reverse. Defenders reply that the joke is clearly satire. They argue that its exaggeration is what makes the bias in the original language visible.

Speculative status

The scenario cannot be tested. It is not known how human societies would develop if most people were autistic. Twin studies suggest that autism is highly heritable, with estimates often between about 60 and 90 per cent. Autism is also linked to many genes and to some environmental factors. Any claim about how such a population would have evolved, or what technologies, economies or politics it would produce, is guesswork. The thought experiment is best understood as a way of examining present-day assumptions, not as a description of a possible world.

Uses

The thought experiment is used for several purposes:

• Teaching and training. It is used in disability awareness sessions and in some university courses to illustrate the social model of disability and the double empathy problem.
• Self-understanding. Some autistic people say the scenario helps them see their difficulties as partly the result of a mismatch with their environment, rather than personal failure.
• Satire and humour. Parodies such as "neurotypical syndrome" use humour to make points about bias in clinical language.
• Design. Architects, planners and employers sometimes use a version of the question, "what if this were designed for autistic users first?", when designing buildings, services or workplaces.

Open questions

• How much of the disadvantage autistic people experience comes from environment and social attitudes, and how much is intrinsic? Researchers and advocates disagree, and the answer probably differs between individuals.
• Does the double empathy problem apply as strongly to autistic people with intellectual disabilities or high support needs, who are under-represented in current research?
• How would an autistic-majority culture resolve conflicting sensory and communication needs among autistic people themselves?
• Would an autistic-majority society develop its own social norms that some autistic people still found hard to follow? Some autistic writers suggest that any majority creates norms that exclude someone.
• Can adjustments such as quiet hours, explicit communication and flexible workplaces benefit people in general, as some "universal design" advocates argue, or do they mainly benefit specific groups?
