Historical overview
The term 'neurodiversity' was introduced by sociologist Judy Singer in 1998. It reframed conditions previously seen purely as deficits as forms of cognitive variation with characteristic strengths and weaknesses.
Scientific basis
Neurodivergent profiles reflect atypical connectivity, dopamine signalling, sensory gating, or executive-function architecture. Twin studies show heritability above 0.8 for autism and around 0.7–0.8 for ADHD.
Strengths
- Heightened pattern recognition (autism)
- Hyperfocus and rapid context-switching (ADHD)
- 3D and global reasoning advantages (dyslexia)
Limitations
- Sensory overload and executive-function bottlenecks
- Social communication mismatches with neurotypical norms
Relationship to other intelligence systems
Human Intelligence
A naturally occurring variant within the human cognitive distribution.
Artificial Intelligence
AI tools function as scaffolding for many neurodivergent workflows.
Future implications
Personalised AI scaffolding - captioning, summarisation, structured planning - is rapidly becoming the dominant assistive technology paradigm.
