Half of workers now worry AI is making them dumber, and the neurologists say they're not wrong.
The Summary
- Nearly half of 2,950 workers surveyed by Workday fear AI agents are killing their critical thinking skills
- Researchers have found heavy AI reliance is quietly deskilling workers, particularly in tasks requiring judgment and creativity
- Neurologists and tech executives recommend building deep expertise, establishing brain routines, and writing first drafts without AI assistance
The Signal
The convenience trap is real. When you can outsource your email responses, first drafts, and analysis to a chatbot, why wouldn't you? The answer is hiding in your brain's wiring. Mental muscles work like physical ones. Stop using them, they atrophy.
Dr. Majid Fotuhi, a Johns Hopkins professor studying neuroplasticity, confirms what workers already sense. The concern isn't hypothetical. Research is documenting real deskilling among heavy AI users, especially in work requiring critical thinking, creativity, and judgment.
"Are we getting too dependent — and does that mean we're getting dumber as a result?"
This isn't Luddite panic. Anurag Dhingra, Cisco's senior VP of enterprise connectivity, frames it as the question that surfaces with every major technological shift. The difference this time is speed and scope. Previous tools automated physical labor or rote calculation. AI automates thinking itself.
The five recommended defenses against brain rot:
- Gain deep expertise in domains where you can out-think the model
- Create deliberate brain routines that force critical engagement
- Write first drafts without AI, even when it's slower
The pattern emerging from tech executives, professors, and neurologists points to a simple truth: AI works best as a second brain, not a replacement brain. The workers who treat it as a shortcut for every cognitive task are the ones watching their skills erode. The workers who use it to amplify expertise they've already built are getting sharper, not duller.
The Implication
If you're reaching for ChatGPT before you've thought through the problem yourself, you're training yourself to stop thinking. The fix isn't to abandon AI. It's to build habits that keep your brain in the game. Write messy first drafts. Solve the problem before you ask the bot to optimize your solution. Get deep enough in your domain that you can spot when the model is bullshitting.
The agents are coming whether you're ready or not. The question is whether you'll use them to think better or stop thinking entirely.
