Test scores across OECD countries peaked around 2012 and have declined since. IQ scores in many developed countries appear to be falling after rising throughout the twentieth century. Nataliya Kosmyna at MIT’s Media Lab began noticing changes around two years ago when strangers started emailing her to ask if using ChatGPT could alter their brains. She posted a study in June tracking brain activity in 54 students writing essays. Those using ChatGPT showed significantly less activity in networks tied to cognitive processing and attention compared to students who wrote without digital help or used only internet search engines. Almost none could recall what they had written immediately after submitting their work. She received more than 4,000 emails afterward. Many came from teachers who reported students producing passable assignments without understanding the material. A British survey found that 92% of university students now use AI and roughly 20% have used it to write all or part of an assignment. Independent research has found that more screen time in schools correlates with worse results. Technology companies have designed products to be frictionless, removing the cognitive challenges brains need to learn. AI now allows users to outsource thinking itself.
I’ve also used it successfully for those kinds of special cases - particularly translating complicated medical documents back and forth to Japanese due to my wife’s treatment.
But I think the caution here is overreliance. Using it in a university setting, where you feed it everything you were supposed to read and understand, and having it write down all the analysis that you were meant to analyze, and what have you personally gained as a result? The article cites students who couldn’t even recall what they’d “written” after submitting an assignment.
You can use it as a tool, or you can use it as a crutch. If you outsource your whole thought process to a computer, I can see the detriment.
