In the 1960s and 70s, Maisie Barrett and Noel Gordon were two black British children wrongly labelled as “educationally subnormal”. They were sent to schools where children were never taught to read or write.

They’re just two examples of a scandal that affected hundreds of children in the UK, one that has never been officially acknowledged.

As adults, Noel and Maisie made a surprising discovery - they were both dyslexic. And with that diagnosis came a profound reimagining of themselves and what had happened to them.

Matthew Syed considers the relationship between ableism, racism and eugenics - concepts with roots that stretch back centuries and which continue to have a profound impact on society today.

With Maisie Barrett, Noel Gordon, sociologist Dr Chantelle Jessica Lewis, Assistant Professor Dr Robert Chapman, and occupational therapist Jenny Okolo.
