Imagine copying a classmate's homework. They copied someone else, who copied you.
By the time the answer reaches you again, it has three different introductions and still nobody has opened the textbook.
That is a useful way to picture a problem researchers are studying: AI writes material for the internet, and future AI learns from that material. The answer sheet starts feeding itself.
An experiment involving 800 models gives us a reason to care about what goes into that loop. It also gives ordinary AI users a useful habit: bring something fresh to the conversation. Paper

Before asking AI for a better answer, give it better material.
An original source, something you observed, or the result of a test can move the work forward. Asking for another rewrite may only change the wording.
The internet becomes the answer sheet
Think of a hypothetical phone review written by someone who never held the phone. They ask AI to generate it from existing information, then publish it.
If that page enters a future training dataset, the next model has another review to learn from. But nobody tested the battery or noticed that the phone gets uncomfortable during a long call.
The amount of writing grew. The amount of firsthand experience stayed the same.
That is the part I find interesting. We can make an article longer, smoother and easier to skim without adding anything that happened in the real world.
What happened in the experiment
Researchers from the University of Maryland and Pangram Labs trained 800 small language models on different mixtures of human writing and AI-generated web text.
When human material was scarce, adding AI text initially helped. As more was added, the benefit reversed. Models with plenty of human text saw harm sooner, measured by how well they predicted unseen human writing. Results
This was a September 30 preprint using small models. It doesn't establish that your favourite chatbot is getting worse, or that all AI-generated training data is harmful. Carefully prepared training examples are a different case from whatever generated articles happen to turn up online. Study
My takeaway is narrower: extra words can be a poor substitute for fresh information.
A better habit for your own AI work
We aren't training models when we write a prompt. Still, the study made me think about how easily we can keep recycling an answer in our own work.
Say you're preparing a post about a tool. You ask AI for a draft, ask it to make the draft interesting, then ask another AI to improve it.
Before doing the third rewrite, try the tool. Record one thing that worked and one thing that annoyed you. Give those notes to the AI.
For research, open the original paper or announcement. Check whether it supports the claim you want to make. Five summaries of the same source give you five summaries to compare; they don't give you five independent pieces of evidence.
A prompt I'd use:
Here are my notes and the original source. Draft from these. Flag claims that need more evidence, and leave gaps where information is missing. Keep my specific observations.
You can still use AI for the writing. Give it something worth writing about.
Why this is real
The researchers released their dataset, models and code so others can inspect the work. Their experiment concerns AI-generated text found on the web, mixed into training material. WildAI
The everyday writing advice above is my interpretation, rather than something their model-training experiment tested.
Final Thought
Before the next rewrite, add one thing you learned outside the chat window. A conversation with a customer, a failed test, or a detail from the original source gives the next draft somewhere new to go.
