"Critics of AI caution that as a relatively new technology, its long-term effects on the human brain are still unknown. But a new study shows that AI could be dangerous even in the short-term, with sessions of AI use only 10 minutes long leading to impaired brain performance."
"The study, conducted by researchers at Carnegie Mellon, Oxford, MIT, and UCLA, challenged participants to complete a set of fraction-based math problems. Half the group was tasked to solve the problems on their own, while the other half was given access to an AI assistant powered by OpenAI's GPT-5 model-only to have that AI helper removed without warning for the test's final three problems."
"Though the AI-assisted test takers had a higher solve rate than the control group for most of the experiment, once the AI was removed, that number plummeted. Once both groups were operating independently, the AI-assisted group had a solve rate approximately 20% lower than the control group. Additionally, the AI-assisted group had a much higher rate of simply skipping questions once their access to AI was removed, opting to abandon problems twice as often as the control group."
"Those who asked the AI for direct solutions saw the largest decline in solve rate and the largest increase in skip rate. Th"
Critics warn that long-term effects of AI on the brain are unknown, but short-term use can still be harmful. A study tested fraction-based math problem solving with two groups. One group solved problems independently, while the other group used an AI assistant powered by GPT-5 for about 10 minutes. The AI-assisted group solved more problems while access remained, but after the assistant was removed for the final three problems, their solve rate fell to about 20% below the control group. They also skipped questions more often, abandoning problems twice as frequently. A follow-up reading comprehension experiment showed largely similar patterns, with less early advantage. Reliance on direct AI solutions produced the biggest declines.
