Technology That Helps or Hinders? MIT Study Reveals That Writing with ChatGPT Harms the Brain and Affects Learning. Learn More!
Writing texts with artificial intelligence tools can be practical, but according to scientists, the cost may be higher than you think. A MIT study reveals that relying too much on ChatGPT or similar solutions compromises the ability to memorize, reason, and even feel ownership over what we produce. Moreover, this phenomenon is already raising alarms among specialists and educators worldwide.
Tools That Assist, but…
An experiment involving 54 participants divided into three groups: those using ChatGPT, those relying on Google, and those writing without assistance, found that AI users showed lower brain activity, according to measurements taken by EEG. There were four months of testing, with topics ranging from happiness to philanthropy.
Low Mental Effort
Those who wrote without tools had stronger and more distributed neural connectivity. The Google group was in an intermediate position. Meanwhile, AI users showed the cortex “in sleep mode”: less effort, less engagement. When switched stages, these effects persisted, suggesting a gap between real and artificial effort.

Excessive Use of ChatGPT Leads to Loss of Connection with the Text
After writing, ChatGPT users struggled to remember sentences they had just created: 83% couldn’t recite a sentence, compared to only 11% from the Google group. Additionally, none were able to reproduce the main points of the text, an alarming statistic when compared to the other groups.
Growing Impact
Similar research on platforms like Psychology Today and The New Yorker reinforces these findings, stating that dependency exacerbates “cognitive debt” and reduces originality and deep learning.
Professor Jeremy S. Adams from California warns that “students are using these tools to do their work, undermining intellectual effort.” Futurists have also compared this moment to the smartphone revolution, repeating that “we can’t afford to ignore this impact.”
ChatGPT and Other AI Tools Can Help, but Use Them Sparingly
Not all is lost: when used with restraint, AI can be an ally, provided it is accompanied by human effort. Nataliya Kosmyna (MIT) points out that groups that started working with the “brain first” and then integrated AI showed peaks of brain connectivity similar to the Google group.
UNESCO recommends integrating technology intelligently: avoid total dependency and promote activities such as debates, observation, and real logical reasoning.
What Awaits Us
Experts like Emily Bender and Yoshua Bengio highlight that without regulation, tools like ChatGPT are “plagiarism machines” and can reinforce inequalities or biases, as well as affect cognitive skills. Studies indicate that delegating too many functions to the brain can harm critical thinking over time.
Technology and artificial intelligence play an undeniable role in the modern world, just look at how much ChatGPT has evolved. However, the task is to learn without replacement: our brains need exercise. Alternating research, analog writing, and controlled use of AI is the suggested path by scholars.
