In this episode, we dive into a provocative new study from MIT’s Media Lab that asks: Is generative AI eroding our cognitive abilities? Using EEG scans, researchers tracked brain activity across 32 regions as participants completed writing tasks—with and without the help of ChatGPT. The results? Eye-opening.
Those who relied on AI showed significantly lower levels of brain engagement, especially in areas tied to memory, semantic processing, and executive function. Over time, many stopped thinking critically altogether, defaulting to AI-generated responses with minimal effort. Meanwhile, participants who tackled the tasks on their own not only showed increased neural activity—they also reported more satisfaction and a stronger sense of ownership.
We explore what this means for learning, memory, and even self-identity in an age of frictionless convenience. The conversation touches on themes from David’s book The Multiplier Effect, reinforcing the idea that AI should augment, not replace, our cognitive processes.
Key Takeaway:
AI doesn’t have to make us dumber—but it can, if we use it as a shortcut instead of a partner. Struggle matters. Engagement matters. And the way we choose to interact with AI may shape the future of human thought.
