Idk, I just read the Blake Ross' (of Firefox) article [1] on having aphantasia, and identify less, rather than more, with how he describes it:
"1. Can you picture my face? >No. But it’s not personal.
2. So you don’t know what I look like? >I know facts ... If you have radiant blue eyes, I may have stored that information. ... I’m unable to project it visually in my mind because there’s no screen.
4. How about picturing something simpler, like a red triangle, or the table right in front of you? >I can’t even understand the question. I can think about the idea of a red triangle. But it’s blackness behind my eyes. Blackness next to my ears. Blackness in every nook and kindle of my brain.
5. You’re just assuming that others can actually SEE things with their eyes. NOBODY can do that, you hypochondriac.
I get it. It’s a “mind’s eye.” I don’t have it."
It's unconvincing. They sort people into categories by a questionnaire, and then find they perform differently on tests that have something to do with vision or imagination. That's it, that's all they've come up with.
