In a [new paper]() currently awaiting peer review, researchers from the school's storied Media Lab documented the vast differences between the brain activity of people who using ChatGPT to write versus those who did not. The research team recruited 54 adults between the ages of 18 and 39 and divided them into three groups: one that used ChatGPT to help them write essays, one that used Google search as their main writing aid, and one that didn't use AI tech. The study took place over four months, with each group tasked with writing one essay per month for the first three, while a smaller subset of the cohort either switched from not using ChatGPT to using it — or vice versa — in the fourth month. As they completed the essay tasks, the participants were hooked up to electroencephalogram (EEG) machines that recorded their brain activity. Here's where things get wild: the ChatGPT group not only "consistently underperformed at neural, linguistic, and behavioral levels," but also got lazier with each essay they wrote; the EEGs found "weaker neural connectivity and under-engagement of alpha and beta networks." The Google-assisted group, meanwhile, had "moderate" neural engagement, while the "brain-only" group exhibited the strongest cognitive metrics throughout. These findings about brain activity, while novel, aren't entirely surprising after prior studies and anecdotes about the many ways that AI chatbot use seems to be affecting people's brains and minds. Previous MIT research, for instance, [found that]() ChatGPT "power users" were becoming dependent on the chatbot and experiencing "indicators of addiction" and "withdrawal symptoms" when they were cut off. And earlier this year Carnegie Mellon and Microsoft — which has invested billions to bankroll OpenAI, the maker of ChatGPT — found in a joint study that heavy chatbot use appears to almost [atrophy critical thinking skills](). A few months later, [*The Guardian* found]() in an analysis of studies like that one that researchers are growing increasingly concerned that tech like ChatGPT is [making us stupider](), and a *Wall Street Journal* reporter [even owned up]() to his cognitive skill loss from over-using chatbots. Beyond the neurological impacts, there are also lots of reasons to be concerned about how ChatGPT and other chatbots like it affects our mental health. As [*Futurism* found]() in a recent investigation, many users are becoming obsessed with ChatGPT and developing paranoid delusions into which the chatbot is pushing them deeper. Some have even [stopped taking their psychiatric medication]() because the chatbot told them to. "We know people use ChatGPT in a wide range of contexts, including deeply personal moments, and we take that responsibility seriously," OpenAI told us in response to that reporting. "We’ve built in safeguards to reduce the chance it reinforces harmful ideas, and continue working to better recognize and respond to sensitive situations." Add it all up, and the evidence is growing that AI is having profound and alarming effects on many users — but so far, we're seeing no evidence that corporations are slowing down in their attempts to injecting the tech into [every part of of society](). **More on ChatGPT brain:** [*Nation Cringes as Man Goes on TV to Declare That He's in Love With ChatGPT*]() ## Author At Futurism, I've often been drawn to unpacking the narratives that underlie technological, scientific and medical progress, with a special interest in areas of conflict and ambiguity that end up setting agendas and steering the fates of both elites and the hoi polloi. I'm a committed generalist, but I often find myself returning to work involving NASA and the private space sector, the effects of AI on media and society, and the mechanics of the pharmaceutical industry, with a specific focus on the spread of GLP-1 drugs like Ozempic and Wegovy. Prior to Futurism, I worked for publications ranging from Media Matters and Truthdig to Raw Story and Bustle. I'm also the author of "Myspace Scene Queens," a 2024 title in Instar Books' acclaimed "Remember the Internet" series. My work at Futurism has been cited by outlets including the New Yorker, Slate, Nieman Lab, the Verge, the MIT Technology Review, the Sunday Times, and the Daily Beast. I grew up in North Carolina, attended the University of North Carolina at Asheville, and now live in Brooklyn, New York. In my free time, I'm an avid reader and music fan; you can probably find me at a local poetry reading, concert, underground rave, or DJ set.
