Breaking down barriers: Overcoming neurodiversity bias

What is neurodiversity bias?

Neurodiversity bias means treating neurodivergent people unfairly. It can be conscious or unconscious. It affects Autistic, ADHD and dyslexic people. It shows up most in how we judge communication.

The bias grows out of social norms. We expect eye contact, small talk and familiar body language. So a person who looks away gets read as dishonest. Someone who finds small talk hard gets judged as poor with people.

This has been measured. Non-autistic observers watched short clips of Autistic people. They rated them less warmly within seconds. They were also less willing to talk to them. More exposure did not soften the judgement. But it disappeared when the clip carried no sound or picture. Style drove the impression, not what the person actually said (Sasson and colleagues, 2017).

So the problem does not sit inside one person. It sits between people. Damian Milton, an Autistic researcher, calls this the double empathy problem. Two people with different ways of being misread each other. The misunderstanding runs both ways (Milton, 2012).

Later work supports this. Autistic people passed a story along a chain of other Autistic people. The details survived as well as they did in the non-autistic chain. Much less survived in the mixed chains. People in the mixed chains also felt less rapport (Crompton and colleagues, 2020).

That changes the question we should be asking. It is not what is wrong with this person. It is what is happening between these people.

The road to assessment in Australia

More than 290,000 Australians have an autism diagnosis. The real number is almost certainly higher. Cost and waiting times keep people out. Some people decide a diagnosis is not the right path for them (National Autism Strategy, 2025).

Australia's first National Autism Strategy names the delay plainly. Three months is the wait a family should expect. The median wait in the public system is 16 weeks. Some services report waits far longer than that.

The wait is not shared evenly. Diagnosis comes later for girls, women and gender diverse people. It comes later for people whose traits are less visible to others. It comes later again in regional, rural and remote areas.

That gap matters for adults too. Many people reach their thirties or forties before anything is named. Years of being misread come first.

These delays feed the bias rather than settle it. Families are left without support and without validation. Old assumptions have time to harden.

What happens at school

School is where many families meet the bias first. Almost 69% of Autistic 5 to 20 year olds in education report difficulty at their place of learning. Only 5.2% of Autistic people hold a bachelor degree or higher. Among people without disability the figure is 35.3% (National Autism Strategy, 2025).

An Australian study recorded seven parents' experience of school exclusion. It names sensory and cognitive overload, teachers without neurodiversity training, and students who never felt safe at school. The cost to parents was practical, financial and psychological. Their own recommendation was clear. Schools should accept autism, use neuroaffirming language and offer flexible learning (Cleary and colleagues, 2024).

When a child cannot get to school, the reason is usually distress. One study of 947 families found 92% of these children were neurodivergent. Nearly all were in real distress before, during or after school. The researchers called it a systemic failure to meet need (Connolly and colleagues, 2023).

That is a useful way to read it. The child is not refusing. The setting is asking for more than it gives back.

What happens at work

The pattern carries into adult life. About half of working age Autistic people take part in the workforce. For people without disability the figure is about 85%. Autistic people are almost six times more likely to be unemployed (National Autism Strategy, 2025).

Underemployment sits alongside it. People work well below their skills and training. Recruitment practice, sensory environments and plain discrimination all play a part.

Many people respond by masking. They hide traits to get through the day. In one study of 262 Autistic adults, women were more likely to mask for practical reasons, such as getting by at work. Masking heavily, or switching it on and off, was linked to worse mental health (Cage and Troxell-Whitman, 2019).

So masking is not a solution. It is the cost of a workplace that has not adjusted.

What this costs families

Bias is expensive, and families carry most of the bill. Our own research with Australian families found the load is measurable. Parents put in 33 extra hours a week. About 10.5 of those hours go to advocacy and admin alone. And 93% of parents say they feel unseen and misunderstood (Making the Invisible Visible).

Those hours come out of paid work, rest and relationships. The strain is not a sign that a family is coping badly. It is the predictable result of a system that leaves them to it.

What we can change

The barriers in this article were built by people. That is the hopeful part. Built things can be unbuilt.

Jacquiline den Houting, an Autistic researcher, makes the point well. Autism is a natural part of human variation. Autistic people are also often disabled, by settings that fail to accommodate them. Both things are true at once, and the second one is the one we can change (den Houting, 2019).

Schools can accept difference instead of correcting it. Workplaces can fix recruitment and sensory environments. Health services can shorten the wait. None of that asks a neurodivergent person to change.

Frequently asked questions

What is neurodiversity bias?

Neurodiversity bias is unfair treatment of neurodivergent people. It comes from expecting one way of communicating and working. Eye contact, small talk and familiar body language get read as competence. Anything else gets read as a problem. The bias can be conscious, but it is usually not.

How long do Autistic Australians wait for an assessment?

The National Autism Strategy names three months as the wait a family should expect. The median wait in the public system is 16 weeks. Some services report much longer. Waits are longest for girls, women, gender diverse people and families in regional and remote areas.

Is neurodiversity bias the same as being rude?

No. Most of it is not deliberate. Research shows people form these judgements within seconds and do not notice doing it. That is why naming the pattern matters. You cannot change a habit you cannot see.

What can I do about it today?

Start with one setting you have some say in. Ask what it expects by default, and who that suits. Then change the setting rather than the person. Small things count, such as written instructions, quieter spaces and more time to answer.
