Brock and Fernette Eide's The Dyslexic Advantage and Imagination

Brock and Fernette Eide's The Dyslexic Advantage flips the usual story about dyslexia. Instead of a deficit to be remediated, they argue the dyslexic brain is wired for a different set of strengths that the reading struggle tends to hide. The Eides, a neurologist and a learning specialist, are careful about what that difference is. On a podcast Brock uses an analogy: "And people with dyslexia are tuned in a different way. They're tuned to be optimized for a different set of functions." It is a different radio setting, not a broken radio. In the Big Five, the strengths they describe cluster on one facet.

Dyslexic strengths cluster on the Imagination facet

The facet is Imagination (O1), under Openness, the tendency to think in rich mental pictures and to model how things could be rather than only how they are. The Eides catalog dyslexic strengths in spatial and big-picture reasoning, exactly the kind of vivid mental modeling O1 measures. Brock describes the spatial version this way: "anything that you can think of in terms of three dimensional space is assisted with this kind of three dimensional spatial reasoning." That is O1 doing heavy lifting, running a scene or a structure in the mind's eye. The reading difficulty is real, but it sits next to a cognitive strength, not on top of an empty space.

The trait-vulnerability point is where this gets useful for reading a profile. Dyslexia is not a Big Five facet, and it does not simply mean high O1; plenty of dyslexic people are inventive and plenty are not. What the Eides show is that the strengths tend to run in an Openness direction, and that school, built around fast reading, systematically hides them. A dyslexic student can look low on everything a spelling test measures while scoring high on the reasoning and imagination no worksheet checks. The profile is not weaker so much as pointed somewhere the classroom rarely looks.

We break the imagery facet down on its own in Imagination (O1). The reframe in The Dyslexic Advantage matters beyond dyslexia: a low score on one channel can sit right beside a high score on another, and a test that only measures the first will call a whole person struggling. If you or your kid reads slowly but builds entire worlds in your head, the Eides would say the second thing is not a consolation prize for the first, it is the main event that school forgot to grade.
