Dyslexia is typically described as a brain disorder or learning difficulty. But new research suggests dyslexia is in fact a vital tool that has helped humanity adapt.
“The deficit-centred view of dyslexia isn’t telling the whole story,” said Dr Helen Taylor of the University of Cambridge, who led the study.
It is a neurological condition caused by the brain being wired a different way, says the International Dyslexia Association, a charity based in the United States.
In the United Kingdom, the National Health Service describes dyslexia as a “common learning difficulty that mainly causes problems with reading, writing and spelling”.
Dyslexia is thought to affect a large proportion of the population – up to 20 per cent. It has clear genetic links and can be inherited from a parent.

In the journal Frontiers in Psychology, researchers at the University of Cambridge in the UK argue that dyslexia shouldn’t be framed as a disorder.
They find that people with dyslexia actually have “enhanced abilities” in certain areas including discovery, invention and creativity.
“We urgently need to start nurturing this way of thinking to allow humanity to continue to adapt and solve key challenges,” said lead author, Taylor
What were the findings?
The researchers concluded that people with dyslexia are specialists in exploration and curiosity. This ‘explorative bias’, as they describe it, plays a “crucial role” in human survival by helping us adapt to changing environments.
Inventiveness and big-picture, long-term thinking are among the skills and strengths linked to these explorative behaviours.
The researchers link dyslexia to human evolution over hundreds of thousands of years, where humans – and our brains – have had to adapt to constant change, rather than one fixed environment.
What does other dyslexia research say?
A growing movement and body of research supports the redefinition of dyslexia as a strength rather than a weakness.
The Value of Dyslexia, a report by professional services firm EY and Made by Dyslexia, a charity that is redefining dyslexia, argues that dyslexic strengths can help employers navigate the changing world of work.
Dyslexic people can show ‘strong’, ‘very strong’ and ‘exceptional’ performance across a range of “cognitive abilities, system skills, complex problem-solving skills, content skills, process skills and technical skills,” the authors say.
These are some of the key skills identified as growing in demand by the World Economic Forum’s Future of Jobs Report 2020.
There is evidence of links between dyslexia and creativity, entrepreneurship and attainment in sport, highlighted in the journal Psychology Today by neurodivergent academic Robert Chapman.
In the US, the Harvard-Smithsonian Center for Astrophysics has researched science skills in people with dyslexia.
Professional astrophysicists with and without dyslexia were tested for their ability to spot a particular characteristic in a black hole.
“The scientists with dyslexia … were better at picking out the black holes from the noise, an advantage useful in their careers,” said dyslexic astrophysicist Matthew H Schneps in an article for the journal Scientific American.
Which well-known people have dyslexia?
British dyslexia charity Helen Arkell lists a host of famous dyslexics of past and present, including physicist Albert Einstein, artists Leonardo da Vinci and Pablo Picasso, film director Steven Spielberg, and John Lennon.
Three American presidents were also believed to be dyslexic – John F Kennedy, George Washington and George W Bush.
Actors Orlando Bloom and Keira Knightley and entrepreneur Sir Richard Branson are among a number of highly successful people with dyslexia profiled in a film by the charity, Made By Dyslexia.
