Should we worry about chatgpt:
While generative artificial intelligences are invited in classrooms. Consequently, offices and even everyday conversations, a MIT study raises a disturbing question: and if Chatgpt, by facilitating our mental tasks, made us … Consequently, a little less intelligent?
A team of researchers from the prestigious Massachusetts Institute of Technology (MIT) recently published a preliminary study analyzing. Therefore, the impact of chatgpt use on human brain activity. Consequently, Led by neuroscientist Nataliya Kosmyna. Meanwhile, her colleagues from MIT Media Lab, this research is based on an unusual method: combining written production, memory and EEG (electroencephalograms) recordings to 32 sensors to observe the functioning of the brain live. In addition, The objective? Nevertheless, Compare the cognitive effects of the use of chatgpt, google or no digital tool during an writing task.
The results, published in May 2025 under the evocative title Your Brain on ChatGPT should we worry about chatgpt (Mit Media Lab, 2025), are disturbing. Similarly, People who used Chatgpt not only displayed lower brain activity, but also reduced neuronal connectivity. Furthermore, In other words, their brain worked less.
The researchers’ alarm signal does not focus on punctual cognitive laziness. Meanwhile, but what they call a “cognitive debt”, namely a progressive loss of fundamental mental skills, such as memory, creativity, or sustained attention.
In fact. However, the participants of the “Chatgpt” group produced less original texts than those of the group “without help”, retained less information on the subjects treated and then struggled to perform similar tasks without AI assistance. The study also notes a significant decrease in alpha and theta waves, associated with working memory and concentration.
This research, although exploratory, is added to a bundle of alerts from the scientific world. A chronicle of New Yorker In June 2025 even speaks of “collective mental should we worry about chatgpt impoverishment”. where AI tends to homogenize our ideas and delegate creative efforts to well -trained machines, but devoid of subjectivity (The New Yorker, 2025).
Can we think effortlessly?
The debate goes beyond neuroscience. Because the efficiency of chatgpt is based on the best: reducing the cognitive cost of a task. By generating answers. texts or ideas in a few seconds, it removes the “mental friction” phase often painful, but essential to learn, create and memorize.
“It’s a bit like entrusting his daily journeys to an autonomous car. ” said British philosopher Henry Shevlin, AI specialist at Cambridge University. “It’s practical, but in the long term, we unlearn to drive.”
Shevlin adds: “It is not the tool that is dangerous, it is the use we make of it. An AI can help think, clarify or structure. But if it thinks in our place, the risk of cognitive should we worry about chatgpt disengagement is real. ”
And this is precisely what the results of the MIT show: the students who used Chatgpt in a passive way. by accepting the answers such as, without rereading or modification, are also those whose neural activity has dropped the most.
An observation reinforced by memory tests carried out afterwards: the participants having copied-paste the responses of the AI held 20 to 30% less content than those who had written themselves. even research on Google.
Conversely. those who used Chatgpt as a reflection partner, asking questions, comparing versions, modifying the answers, maintained a significant brain activity.
Should we panic? No. To reflect on? Yes.
Used with discernment, Chatgpt can be a fascinating educational tool. It can stimulate curiosity, simplify access to information and even help structure thought. But passively used, as a response machine, it risks short-circuiting the very mechanisms should we worry about chatgpt of learning.
The stake is therefore educational. cultural and perhaps even existential: do we want to continue to think by ourselves or simply delegate thought to a fluid and polished machine?
As always, technological progress only becomes dangerous if it is adopted without conscience. And if the brain is a muscle, then it is up to us to choose if it falls asleep … or trains.
What does the study show in the youngest?
The study focused only on young adults. but several experts, including neuropsychologist Michel Desmurget (author of The Cretin Digital Factory), sound the alarm for children and adolescents. “The development brain is malleable. If it is nourished by automatisms. premmed content, it does not form the deep connections necessary for critical thinking, “he recalls in a column published on France Culture.
In the United States. the New should we worry about chatgpt York Post Recently reported a wave of concern in schools, where teachers note a drop in the level of understanding and writing among students who abuse genetive AI (Nypost, 2025).
Some British schools even experience “no AI” areas to stimulate autonomous thinking and restore the taste for cognitive effort.
