Why Letting AI Think For You Is Weakening Your Brain

You've probably heard the idea that AI might be making people a bit lazier, a bit less sharp. What you might not know is that MIT actually tested it, with real brain scans, and what they found is worth taking seriously. In this episode I break down that study properly, what happened when people wrote essays with ChatGPT versus with nothing but their own head, and why the group who used AI couldn't even quote their own writing back afterwards. I explain the mechanism behind it, why effort is what actually builds your brain's capacity, and what happens when AI quietly removes that effort from your day. I also share something I noticed working with a group of senior partners at a big four accountancy firm years before any of this existed, and why I think the same pattern's now happening to people decades earlier in their careers. Then the practical part. What I'd actually build into a week to offset it, and why it doesn't need to be complicated. If you think for a living, this is one you don't want to skip. This week's newsletter goes deeper on the research behind this, including a second study most people haven't seen. It's free.
