@crysophylax While I understand arguments against speculating about public figure's neurotypes, I also think ND-coding and why it's so much more prevalent than good explicit representation is important to discuss. To resolve that, I've been trying to consider this sort of thing to be a trend rather than individual.
I think there is a body of work drawing on specific character archetypes, and authors can write characters of this archetype without realizing that those archetypes are neurodivergence. As I mentioned, I think the reason authors choose to draw on that specific archetype is their own experience, but I'm sure for a sizeable number, they're instead drawing from experiences of their friends or family members, or even just of a general archetype in media.
I think then we can say both that any given author has written deeply ND-coded characters without knowing those traits are neurodivergent and also that frequently that happens due to the author's own neurodivergence without also claiming that that *particular* author is ND.
I think there are parallels here with how to approach the difference between "This art clearly depicts a queer experience" and speculations about that particular author's sexuality.
Fantastic point about ND literary theory.
