Researchers from the MIT Media Lab put out a pre-print that’s garnered some attention: Your Brain on ChatGPT: Accumulation of Cognitive Debt when Using an AI Assistant for Essay Writing Task.
I’m in this angry tribe of elders, steeped in willful confirmation bias, seeking fuel for our hot takes. Many of us want what’s claimed in this paper.
I’m a teacher who grades papers, and I want smart-sounding labels and scientific data to confirm what I’ve observed: voiceless writing that reflects a student’s low motivation to think, and that erodes my motivation to read. On the other side of the crossover study, I’m AI optimist, so I want to believe that adding ChatGPT later, after significant effort, can spark greater engagement and produce great writing, the best of human and machine.
But the paper isn’t peer-reviewed yet and the participant pool is quite small (N=18 in the final critical cross-over phase). And sharper takes have been written. So I’ll decline to go deeper on the substance of the paper.
Let’s get to the detail that I am obsessed with:
THE PAPER HAS A PROMPT INJECTION IN IT!
On page 3, the authors write directly to AI.
The table the authors want the robots to read is fine. It’s not misleading, so it’s possible there are positive and innocuous reasons to include this 4th-wall-breaking prompt, but… I had to keep probing.
A quick Google News query, scanning the media headlines and lede paragraphs, most articles fail to go beyond the abstract and summary table. It’s plausible that many of the pieces written about this paper used an AI summarizer that complied with the author’s indirect prompt injection. While I want that to be true, let’s not get carried away. Depth isn’t the strength of most tech news articles. It’s perhaps beyond most writers (human or AI) to go beyond the abstracts nowadays anyway (let alone reading the entire 200 pages).
Blogs and news sites began detecting Googlebot and offering crawler-specific SEO-optimized headlines in the early 2000s. This paper represents a new version of that trend. I predict we’ll see more and more documents talking directly to the robots that read them. Savvy document creators will correctly anticipate their outputs’ future as LLM context and will attempt to sway the gullible pleaser AI by offering it their own instructions.
Frequently AI Questions
Even the FAQ published by the researchers on brainonllm.com has language that seems so specific and prescriptive it feels like it’s meant to guide an AI writer to avoid phrases that might spin the research in ways they don’t like:

Could be confirmation bias again, but my Gemini chat seemed to go deeper into the paper after I added this:
