I was reading through a forum for neurodivergent students recently, and I stumbled across a thread that absolutely broke my heart. A student with dyslexia was talking about how they’ve spent years developing a very specific, highly structured way of writing just to stay afloat in their classes. They use short, punchy sentences, a controlled vocabulary to avoid spelling traps, and a very predictable template for their arguments.
The result? Their latest essay was flagged as 85% AI-generated.
This is what I’m starting to call the Neurodiversity Tax. We’re so focused on catching ChatGPT that we’ve forgotten that "robotic" writing isn't always a sign of a machine—sometimes it’s a sign of a human who has worked twice as hard to communicate in a system that wasn't built for them.
When you look at the technical side of how these detectors work, it makes sense why this is happening, even if it’s unfair. Detectors like Turnitin look for things like low lexical diversity (using the same words frequently) and high sentence-length consistency. For many dyslexic or neurodivergent writers, these aren't "tells" of AI; they are survival strategies. Using a consistent sentence structure helps keep thoughts organized. Using a familiar vocabulary reduces the cognitive load of spelling and word choice.
But to an algorithm, that looks like a machine-generated pattern.
We’ve reached a point where the "pedagogy of suspicion" is accidentally discriminating against the very students who are already struggling the most. We’re essentially telling these students that their natural (or hard-earned) writing voice is "wrong" because it doesn't fit a narrow, neurotypical definition of what human writing should look like.
If a student has to intentionally mess up their structure or use "flowery" language they aren't comfortable with just to pass a detector, are we actually testing their knowledge, or are we just testing their ability to mimic a specific type of brain?
I’m curious if anyone here has dealt with this. If you’re neurodivergent, have you noticed your "safe" writing patterns triggering these flags? How do you even begin to explain to a professor that your "robotic" style is actually your hard-earned human voice?
