The 15% You Might Be Missing: Unlocking Talent in Every Type of Mind
Quick answer:
Around one in five people is neurodivergent, yet many never disclose it at work. The best organisations focus less on diagnosis and more on designing work that suits different minds from the start. Most adjustments cost little and improve performance for everyone.
The older I get, the more I question whether organisations confuse difference with deficiency.
Awareness of neurodiversity has improved. But much of the conversation still revolves around diagnosis, disclosure and adjustments. Those things matter. They are not the most interesting part of the story. The more interesting conversation is about talent.
How common is neurodiversity in the workplace?
Around 15 to 20% of people are neurodivergent, which is roughly one in five employees.
That means one in five people may process information, communicate, learn or solve problems differently from the majority around them. Some are autistic. Others have ADHD, dyslexia, dyspraxia or another form of neurodivergence.
Some have a formal diagnosis. Many do not. Disclosure is deeply personal, so most leaders never know how many neurodivergent people they employ.
The result is that organisations routinely underestimate the hidden talent already sitting in their workforce.
Why do neurodivergent employees not disclose at work?
Most people stay silent because disclosure feels risky, not because support is unwanted.
Some worry about stigma. Some fear being overlooked for promotion. Others simply want to be recognised for their contribution, rather than viewed through the lens of a condition.
This creates a problem, because many organisations treat disclosure as the starting point for support. They wait for someone to identify themselves before considering adjustments.
If a large share of people never disclose, a large share never receive support. And the organisation misses the chance to ask a better question altogether.
The hidden cost of masking
Masking is the constant energy neurodivergent people spend adapting to fit workplace expectations.
They rehearse conversations. They monitor how they communicate. They analyse interactions long afterwards and suppress behaviours that might seem unusual. Most people adapt to some degree, but masking goes much further. It is a constant cognitive burden, carried simply to appear to be operating in the right way.
Viewed this way, it becomes easier to understand why some exceptionally capable people burn out in workplaces that were never designed with them in mind.
We invest in wellbeing programmes and resilience training. But we may be treating symptoms while ignoring the cause. Some people are exhausted not by the work, but by the energy it takes to fit in.
Why good workplace design beats special treatment
The adjustments that help neurodivergent employees are usually just good management that helps everyone.
A common misconception is that supporting neurodivergent people requires costly, specialist intervention. In reality, most of the changes that matter are simple, and they improve the experience for the whole team.
Take recruitment. Traditional interviews reward confidence, speed and performance under pressure, qualities many roles rarely need day to day. Sharing questions in advance, explaining the process clearly and offering practical assessments does not lower standards. It removes barriers that stop people showing what they can actually do.
The same applies to onboarding. Clear first-week plans, defined milestones and written expectations help everyone settle faster. Nobody suffers from knowing what is expected of them.
If you want practical places to start, focus on ten straightforward adjustments:
Share interview questions in advance where appropriate.
Offer alternatives to purely interview-based assessments.
Clearly explain recruitment stages and timelines.
Provide structured onboarding plans before day one.
Make quiet working spaces available.
Offer flexibility where operationally possible.
Use written communication for non-urgent matters.
Send meeting agendas in advance and document decisions afterwards.
Put expectations and objectives in writing.
Hold regular, structured one-to-one meetings.
None of these are revolutionary. Most cost little or nothing. What they require is a willingness to challenge long-standing assumptions about how work should be organised. This is the heart of universal workplace design: building systems that work for a broad range of people from the outset, rather than waiting for individuals to request support.
What leaders get wrong about neurodiversity
Most organisations make the same four mistakes.
The first is waiting for a formal diagnosis before acting. With long assessment waiting lists across the UK, that can delay support for months or years. Good practice should not depend on paperwork.
The second is focusing on conditions rather than individuals. Leaders feel they must understand every detail of autism, ADHD or dyslexia first. But most employees are not looking for clinical expertise. They want understanding, flexibility and clarity.
The third is treating neurodiversity as a compliance issue. Legal duties matter, but organisations that focus only on risk miss the bigger opportunity: attracting, retaining and unlocking talent. Diversity of thought is often a competitive advantage.
The fourth is assuming fairness means treating everyone the same. It does not. Fairness is giving people what they need to succeed. The strongest leaders see adjustments not as exceptions, but as part of building a high-performing workplace.
How this connects to belonging and self-editing
When work is not designed for how someone thinks, they spend their energy adapting instead of contributing.
That pattern will sound familiar. It is the same dynamic behind self-editing, where people edit themselves at work to fit in rather than contribute fully. It connects to belonging, which begins on a new starter's very first day and shapes how much of themselves they bring.
The common thread is design. When environments only suit one way of thinking, talented people quietly exhaust themselves trying to fit. When they suit a broader range, people are free to do their best work.
In a nutshell
Around one in five people in the workforce may be neurodivergent, yet many never disclose it.
The most effective organisations focus less on diagnosis and more on creating environments where different people can succeed. Most adjustments cost little or nothing and improve the experience of the entire workforce.
This is not simply an inclusion issue. It is a talent, retention and leadership issue. The organisations that thrive will be those that unlock potential rather than expect conformity.
Because there is no single blueprint for intelligence, creativity or problem solving. If one in five people may think differently, that is an opportunity none of us can afford to ignore.
Frequently asked questions
What percentage of the workforce is neurodivergent?
Around 15 to 20% of the population is neurodivergent, roughly one in five people. This includes autism, ADHD, dyslexia, dyspraxia and other forms. Because disclosure is personal and many people never disclose, most organisations underestimate how many neurodivergent employees they have.
Why do neurodivergent employees choose not to disclose?
Common reasons include fear of stigma, worry about being overlooked for promotion, and a desire to be recognised for their work rather than a condition. Because many organisations rely on disclosure to trigger support, people who stay silent often never receive it.
What is masking at work?
Masking is the constant effort neurodivergent people spend adapting their behaviour to fit workplace expectations, such as rehearsing conversations or suppressing natural behaviours. It carries a heavy cognitive load and can lead capable people to burn out in environments never designed with them in mind.
How can employers support neurodivergent staff without high costs?
Most effective adjustments are low or no cost: share interview questions in advance, offer practical assessments, provide structured onboarding, make quiet spaces available, use written communication, and put expectations in writing. These help the whole team, not just neurodivergent employees.
What is universal workplace design?
Universal workplace design means building clarity, structure and flexibility into how an organisation operates from the outset, so it works for a broad range of people, rather than waiting for individuals to request support. It treats good accessibility as good management for everyone.
Is supporting neurodiversity a compliance issue or a talent issue?
Both, but the bigger opportunity is talent. Legal duties matter, but organisations that focus only on risk miss the chance to attract, retain and unlock capability. Diversity of thought is frequently a competitive advantage, not just a social good.
