Study Warns ChatGPT May Be Harming Our Brains, but Teachers Say Banning It Isn't the Answer
- In a 2025 MIT study, 54 adults completed essay tasks using ChatGPT, Google Search, or only their own knowledge to assess cognitive engagement.
- Researchers found that individuals who depended on ChatGPT during essay writing demonstrated diminished brain engagement and poorer memory performance, a phenomenon the study labeled as 'cognitive debt.'
- These findings raise concerns about metacognitive laziness from AI overuse, which can impair critical thinking in both education and business analytics contexts.
- The ChatGPT group averaged a CES-AI cognitive engagement score of 2.95, significantly below the control group’s 4.19, indicating less mental effort and attention.
- Experts and educators argue against banning AI, advocating for mindful, reflective use that preserves human judgment and fosters skill development alongside AI assistance.

Can ChatGPT ‘rot’ your brain as MIT study claims?
Since ChatGPT appeared almost three years ago, the impact of artificial intelligence technologies on learning has been widely debated. Are they handy tools for personalised education, or gateways to academic dishonesty?Most importantly, there has been concern that using AI will lead to a widespread “dumbing down”, or decline in the ability to think critically. If students use AI tools too early, the argument goes, they may not develop basic skil…
Study warns ChatGPT may be harming our brains, but teachers say banning it isn't the answer
This academic year, in high school history teacher Jeanne Barrs eyes, is the year students use of ChatGPT became ubiquitous.With generative AI tools like ChatGPT becoming more deeply integrated into classrooms and workplaces, new research is also raising red flags about what we might be giving up in return: our brainpower.Some students are making poor choicesshortcutting the thinking process and denying their brains the opportunity to build capa…
Students offload critical thinking to ChatGPT, becoming cognitively passive
Students using ChatGPT were less likely to engage in deep processing, meaning they were more prone to skimming and relying on surface-level understanding. They reported exerting less mental effort, reflecting a decrease in self-regulated thinking, and were more susceptible to distractions, indicating weaker sustained attention.
