There's yet another study about how bad AI is for our brains

Researchers found that ​​using the technology helps at first, but "it comes at a heavy cognitive cost."

A group of researchers from across the US and the UK have conducted a study on what AI does to our brains and the results are, in a word, grim. These results were published in a paper called "AI assistance reduces persistence and hurts independent performance" which kind of tells you everything you need to know.

β€œWe find that AI assistance improves immediate performance, but it comes at a heavy cognitive cost,” the study declares. Researchers went on to state that just ten minutes of using AI made people dependent on the technology, which led to worsening performance and burnout once the tools were removed.

The study followed people who use AI for "reasoning-intensive" cognitive labor. This refers to stuff like writing, coding and brainstorming new ideas, which are some of the most common use cases.

The researchers recruited 350 Americans, who were asked to complete some fraction-based equations. Half of the participants were randomly granted access to a specialized chatbot built on OpenAI's GPT-5 for help and the others had to go it alone. Halfway through the exam, the AI group had their access cut off.

This led to a steep decline in correct answers by the AI group and many instances of people simply giving up. This result, in which performance and perseverance both dropped, was repeated in a larger experiment with 670 people. Finally, the scientists performed one final experiment with reading comprehension questions, and not math. The results were more of the same.
