In a new study, researchers claim to provide the first causal evidence that leaning on AI to assist with “reasoning-intensive” cognitive labor — mental tasks ranging from writing to studying to coding to simply brainstorming new ideas — can rapidly impair users’ intellectual ability and willingness to persist despite difficulty.
“We find that AI assistance improves immediate performance, but it comes at a heavy cognitive cost,” the study declares of its findings. “After just [about] 10 minutes of AI-assisted problem-solving, people who lost access to the AI performed worse and gave up more frequently than those who never used it.”
The study, which was conducted by a multidisciplinary cohort of scientists from across the United States and United Kingdom, has yet to be peer-reviewed. But it builds on a growing body of research suggesting that extensive AI use can distort and dampen users’ thinking and independence, and as experts work to understand the impacts of widely-used chatbots on people as they unfold in real-time, they’re warning that outsourcing cognitive tasks to AI tools could put humans in a “boiling frog” conundrum — in which an unwitting, bit-by-bit erosion of our cognitive “muscles” leads to formidable challenges in the long-term.
“If sustained AI use erodes the motivation and persistence that drive long-term learning, these effects will accumulate over years, and by the time they are visible, they will be difficult to reverse,” the study urges. “This is analogous to the ‘boiling frog’ effect, where each incremental act feels costless, until the cumulative effect becomes overwhelming to address.”
To conduct the study, the researchers recruited a cohort of about 350 Americans, who were asked to try to complete a brief series of fraction equations. A little more than half of participants were randomly granted access to a chatbot — a specialized bot built on OpenAI’s GPT-5 and provided with the specific answers for each question on the brief exam — for help. Everyone else was funneled into an AI-free control group.
At first, the results revealed, the chatbot proved expedient in helping AI-aided participants breeze through the test. But halfway through the short exam, access to the AI was suddenly cut off — at which point participants’ ability to work through the reasoning questions without AI assistance quickly declined, as did their will to keep working at a problem when the going got tough.
For a follow-up experiment, the researchers recruited another, larger group of nearly 670 participants. They were once again split into two roughly-equal halves and asked to complete a brief mathematical reasoning test, with one group given access to a chatbot assistant — only to once again be suddenly abandoned by their AI companion, leaving them to cognitively fend for themselves. The results were pretty much the same: performance dropped, as did perseverance.
These same outcomes persisted once again in a final experiment, in which about 200 more participants were asked to complete a brief series of reading comprehension questions, showing that such results aren’t simply limited to math problems.
“People’s persistence drops,” said University of California, Los Angeles assistant professor Rachit Dubey, a computational cognitive scientist who coauthored the study alongside peers from the Massachusetts Institute of Technology, Carnegie Mellon University, and the University of Oxford, in an interview with Futurism.”Once the AI is taken away from people, it’s not that people are just giving wrong answers. They’re also not willing to try without AI.”
