I'm a dyslexic, and I was given extra attention is school that significantly helped me. I have a pet theory, and this article seems to agree with it to some extent, that there are several or many different neurological conditions that are often put in the same label 'dyslexia'. I hope that one day more research is done to separate out the different underlying neurological states so we can better teach all children to read. The article's conclusion -- that because dyslexia is an inprecise term we should abandoned it to an even less precise term -- is flawed. We should instead work towards creating more precise language and understanding around the different ways low literacy manifests in children.
If I was an incredibly wealthy technocrat this would be a pet research field of mine. If we can improve childhood literacy education it will have massive returns on that person's lifetime contribution to society. Understanding how the brain processes language also has significant implications for other lines of research as well.
