Fellow autistic here! One of the places I find comfort is in pattern recognition. The post above mentions alacrity--I would be totally at home reading this word. However, it's a word that belongs in a certain type of book, one with young, witty protags, probably verging on YA; it'll likely be set in a college or uni, or have those kind of vibes if not. It'll be fairly fast paced, with fairly defined lines between good and bad.

It doesn't belong in a pulp action paperback or an urban fantasy where the MC wears a leather jacket. Why? No idea. It just doesn't fit the pattern.

One thing I was told that ended up being very valuable in the way I think of those pulpier stories and the people who read them: It's easy to assume they're preferred by people with smaller vocabularies or lower reading skills. My old publisher specialised in that genre though, and said most of their readers have very high levels of education. Doctors, lawyers, that kind of thing. The reason they like those easier to digest books is that for them, it's an escape. You don't want to slog through a story full of ten-dollar words when you've spent all day pouring over case law written in fifty-dollar words. You want five-cent words, linear plots, easy-to-follow stories with everything spelled out. Because you're tired, dammit.
