Abstract
In the history of the reading field, the quest to identify subtypes of reading disability has been as enticing as it has been futile. There is enormous face validity to the idea that poor readers differ among themselves in the way they have become poor readers and in the cognitive underpinnings of their disability. Yet the field has failed to progress beyond step one in defining separable groups of disabled readers — that is, subgroups who are behaviourally, genetically, and physiologically different from other poor readers.
