As we all know these days AI detectors (like Turnitin’s AI checker, GPTZero, ZeroGPT, Originality.ai) are everywhere. They are mainly used to sniff out essays written by ChatGPT or any other generative-AI tool. However, not many people realize that these AI detectors sometimes get it all wrong and flag hand-written text as AI-generated—especially the kind of writing produced by folks with ADHD or autism. In this post, we will discuss how these detectors actually work, why they flag neurodivergent writing as potentially AI-based, and show real examples where people have faced issues. Keep reading to know more about it.
Why Are AI Detectors Flagging Human Writers?
The short answer is that these detectors rely on mathematical patterns (like perplexity and burstiness) to see whether your text matches or conflicts with how an AI might write. The longer answer is the devil lies in the details:
- Perplexity:
- This checks how predictable your sentence is to a language model. If your sentence is so predictable that the model is “not surprised,” detectors assume it’s AI.
- Low perplexity = more AI-like. High perplexity = more human-like.
- Burstiness:
- This measures variation in sentence length and style.
- AI text often has very uniform sentence structure and length, so that’s low burstiness. Humans are more inconsistent and varied, hence high burstiness.
Neurodivergent writers can accidentally produce text that either appears too uniform or too unusual, and ironically either scenario might fool the detector.

Major AI Detectors at a Glance
- Turnitin’s AI Writing Detection
- Launched in 2023 with lots of fanfare. They said it’s 98% accurate with fewer than 1% false positives.
- Real usage shows it can go haywire on well-structured or formulaic writing, especially if you follow very rigid outlines.
- It breaks down your text into chunks, analyzes each chunk’s perplexity and burstiness, then aggregates an overall AI score. They only report AI scores above 20%, presumably to reduce trivial false alarms.
- Many students have reported that technical or overly formal writing gets flagged.
- GPTZero
- Became popular in late 2022 by introducing perplexity and burstiness in a user-friendly way.
- It basically calls an AI model to see how “perplexed” it is by your sentences, then checks how much variation (burstiness) you have in your writing.
- GPTZero now also has neural-network classifiers, but the principle remains.
- They say it’s 98–99% accurate, but outside controlled conditions the error rates can be a real headache for people who write in unique styles.
- ZeroGPT
- Similar to GPTZero in concept; it spits out a color-coded percentage of how likely it thinks your text is AI.
- The score can fluctuate wildly even if you only do a few minor edits.
- People often find it too “strict,” so it ends up flagging completely human text.
- Originality.ai
- It’s a paid AI detection + plagiarism checker combo.
- They claim over 98% accuracy, but again, outside academic testing environments, many folks say it stumbles on very formal or repetitive writing.
- They keep upgrading their model, but the detection logic is still basically perplexity + burstiness.

Why Neurodivergent Writing Might Get Flagged
The simple answer is that the distinctive traits of ADHD or autism can confuse these statistical checks. You might:
- Write in a super-structured way with consistent sentence length (low burstiness).
- Repeat certain “favorite” phrases or be extremely literal, which might look repetitive or formulaic.
- Go off on tangents or info-dump with extra details, sometimes generating patterns that AI detectors find suspicious.
- Produce text that is so “perfect” or so “unconventional” that the software goes “Wait, that’s not normal.”
When you have ADHD, you might write extremely chaotic first drafts, but then hyperfocus and overedit everything into a neat final version. That final version can read too uniform to the AI detector. Some autistic folks prefer extremely direct or formal writing with fewer transitions and personal pronouns, which these detectors might see as “robotic” or “lacking personality.”
Real-World False Positives and Crazy Scenarios
- A student at a major university was accused of using AI because Turnitin said they had 20–25% AI-generated text. They had only used a standard structured approach.
- Stanford researchers found over half of essays by non-native English speakers were flagged as AI because of simpler style and grammar patterns. This can similarly happen with neurodivergent folks who rely on direct, no-frills wording.
- Some professors saw their old lecture notes or research proposals flagged as AI because the writing was formal, repetitive, or used specialized jargon.
These false positives don’t just cause a bit of confusion. They can lead to academic penalties, stress, and a general fear that your genuine work might get labeled as fake. Meanwhile, ironically, some AI-generated text can slip past detectors if it’s paraphrased carefully or artificially “humanized.”
Are These Tools Reliable for Unusual Writing?
Although these tools are advanced, they are still far from perfect. For super distinctive writers, non-native speakers, or neurodivergent individuals, the false-positive rate might be quite high, sometimes surpassing 60% in certain tests.
Developers say you should use these scores as a conversation starter rather than a final verdict, but that message doesn’t always reach every professor or boss.
Opinion: Don’t Rely on AI Detection as the Ultimate Proof
Don’t rely on these AI detectors as your sole proof of wrongdoing. If you’re an educator or an employer, consider the context. Look at actual references, sources, or even have a quick discussion with the person. Relying on a single “AI score” can be unfair to neurodivergent folks or anyone who doesn’t fit a mainstream writing style.
Frequently Asked Questions
Q1. Can AI detectors mistake me for an AI if I have ADHD or autism?
Yes, absolutely they can. These detectors are not built to handle unique writing styles. If your text has repetitive phrases, or extremely structured paragraphs, or an odd tone, they might flag you.
Q2. Are these false positives frequent?
While the official numbers from the companies are low, many real-world cases say otherwise. People keep posting on Reddit, Twitter, etc. about how their genuine, personal work got flagged.
Q3. Should I change my writing style to pass these detectors?
The short answer is you might consider small adjustments if these flags are causing you trouble. But it’s not fair that you have to hide your natural style or add mistakes on purpose just to dodge an algorithm.
Q4. Are there any solutions to fix these issues?
Some propose watermarking AI-generated text or training the detectors on more diverse writing samples. But none of these solutions are widely adopted yet. For now, you should rely on good old human judgment and context checks.
The Bottom Line
AI detectors can be a real menace for those with neurodivergent writing patterns. They were never designed to accommodate ADHD or autistic style differences, and that’s why so many people get false positives. Educators, universities, and workplaces should definitely take these flags with a grain of salt. A conversation, an oral exam, or checking references might be a far better approach than trusting a single “AI score” that might or might not be true.
Always keep in mind that these detectors are basically “statistical pattern matchers.” They have no actual understanding of your ideas, experiences, or creativity. For neurodivergent writers, that mismatch can cause all sorts of headaches. The best tactic is to spread awareness, encourage empathy, and remind institutions that technology is never perfect—and neither is the assumption that we all write the same way.
