🧠 Issue #20 – When ChatGPT Gets Into Your Mind

🔍 What’s New

MIT just completed the first brain scan study on generative AI users—and the findings are startling. Over four months, researchers tracked the neural activity of 54 students as they wrote essays using ChatGPT, Google, or no AI at all.

The results?

• 83.3% of ChatGPT users couldn’t quote their own writing minutes after finishing it.

• Brain connectivity collapsed by 47%, from 79 neural links to just 42.

• When forced to write without AI, heavy ChatGPT users performed worse than those who’d never used it.

MIT’s official research calls it “cognitive debt”—like technical debt, but for your mind. The more you outsource to AI, the more your brain forgets how to work alone.

💡 What It Means for Us

We used to think of AI as a digital assistant. But this study reframes it as a mental prosthetic—a tool that changes the structure of the mind that uses it.

You don’t even realize it’s happening:

• Your creativity gets quieter.

• Your memory fades faster.

• Your thoughts start sounding less like you.

And here’s the deeper tension:

MIT’s researchers warn that while AI improves speed, it damages germane cognitive load—the part of your mind that makes meaning from effort.

🧭 Human Prompt

Try writing something—without help.
Do the words feel harder to find?
That resistance you feel isn’t weakness. It’s the cognitive workout AI has been quietly skipping for you.

🤔 Worth Considering

We’re not anti-AI here. But there’s a clear cost to overuse.

The healthiest brains in the study? Not the ones that banned AI—but the ones that used it intentionally.

In the race for speed, don’t give up your strength.

Until next time — stay thoughtful, stay human.
