What is Neurodiversity? A Systems View
Neurodiversity is not a problem to fix. It is a system to understand.

The Definition
Neurodiversity is a term that describes the natural variation in how human brains are wired. It is not a list of deficits. It is not a hierarchy of normal versus abnormal. It is a broad spectrum of neuro-types, each bringing its own way of processing, perceiving, and engaging with the world.
The concept invites a fundamental shift in perspective: away from asking "what is wrong with this person?" and towards asking "what in this environment is not working for this person, and how do we change it?" It moves the focus from fixing the individual to understanding the system around them, and towards identifying how they can lean into their strengths, adapt their surroundings, and build conditions in which they genuinely thrive.
This is the systems view. The person is not the problem. The fit between the person and their environment is where the work begins.
How Neurodivergent Brains Work Differently
It is important to hold both truths at once. Yes, neurodivergent brains often bring remarkable strengths. And yes, being neurodivergent can be genuinely challenging.
Take dyslexia as an example. Dyslexia is defined as a difficulty with reading and/or spelling fluency. In isolation, that might sound manageable. But consider how much of modern working life is built on the written word: emails, reports, instant messages, policies, instructions. The potential for a dyslexic person to experience friction in their daily life is high, and often invisible to everyone around them.
Neurodivergence can also affect attention, working memory, and executive functions: the cognitive architecture that underlies planning, prioritising, shifting between tasks, and regulating responses to the demands of daily life. These are not character flaws. They are differences in how the brain organises and processes information.
Understanding this is not about lowering expectations. It is about raising the quality of the environments and systems in which people are expected to operate.
Who or What is Normal Anyway?
Around 20% of the population is neurodivergent. That is one in five people. In any classroom, any team meeting, any family gathering, neurodivergent people are already in the room.
The concept of "normal" when it comes to brain wiring is far narrower than the reality of human diversity. For much of history, the neurodivergent 20% have been asked to adapt to systems designed by and for the neurotypical majority. The systems view asks a different question: what would it look like if we designed for the full range of human variation from the start?
Neurodiversity Shows Up in Daily Life
Neurodiversity is not an abstract idea. It shows up in the texture of everyday experience.
At work, it might look like an employee who produces extraordinary output during periods of hyper-focus, but who struggles to manage a calendar or respond to emails in a timely way. It might look like burnout that arrives without warning after months of masking, of working hard to appear "normal" in an environment that was never quite built for the way they think.
In relationships, it might show up in different communication styles, in the way someone processes conflict or expresses care, in the effort it takes to navigate social expectations that others seem to read effortlessly.
In learning, neurodivergence can affect how information is processed, how memory works, how ideas are organised and retrieved. Someone might understand complex concepts deeply but struggle to demonstrate that understanding in a conventional test format.
None of these are failures. They are signals. They are the system asking to be looked at differently.
Not Sure if You're Neurodivergent?
Many adults have spent years developing sophisticated strategies to work around their differences, often without knowing why certain things feel harder than they should. Assessment can bring clarity: not to label, but to understand. When you understand how your brain works, you can stop working against yourself and start building a life and a working environment that genuinely fits.
If any of this resonates, that is worth paying attention to.
Systems of Support offers cognitive profile assessments, coaching, and consultancy for neurodivergent people and the organisations that support them.
