A child being unable to learn to read at the ‘normal’ rate is only an issue in a literate society. For the vast majority of human existence an inability to learn to read was not an issue at all. In fact if you go back, say 10,000 years, an ability to read would be abnormal.
This article looks at the issue of normality and disability. I put the case that the disability label comes from a faulty model of cognitive diversity. The disability label is damaging and gives the wrong impression. I present an arguement for change.
