Study Finds AI Assistance Boosts Immediate Performance but Undermines Persistence
Key Points
- Researchers from the US and UK published a study titled "AI assistance reduces persistence and hurts independent performance".
- In a test of 350 Americans, participants using a GPT‑5 chatbot initially performed better on math problems.
- When AI access was removed, the same participants showed a sharp decline in accuracy and gave up on many questions.
- A larger replication with 670 participants and a reading‑comprehension trial produced identical results.
- Co‑author Rachit Dubey warned that AI reliance could erode motivation and persistence, especially in education.
- Limited use of AI for hints caused less damage than using it to generate full answers.
- The study is not yet peer‑reviewed but highlights potential long‑term cognitive costs of AI dependence.
Researchers from the United States and the United Kingdom published a study titled "AI assistance reduces persistence and hurts independent performance," showing that while AI tools can improve short‑term task results, they also create a reliance that hurts long‑term cognition. In experiments with hundreds of participants, those who used a GPT‑5‑based chatbot performed better at first but saw a sharp decline in accuracy and perseverance when the tool was withdrawn. The authors warn that widespread AI deployment in education could erode learners’ motivation and creativity.
A joint team of researchers from the United States and the United Kingdom released a paper called AI assistance reduces persistence and hurts independent performance. The study examined how short‑term use of artificial‑intelligence tools affects people’s ability to think and work without help.
Participants—350 American volunteers in the first trial—were asked to solve a series of fraction‑based equations. Half received access to a specialized chatbot built on OpenAI’s GPT‑5, while the other half tackled the problems on their own. Midway through the test, the researchers cut off the AI group’s access. The immediate effect was a modest boost in correct answers for the AI users, but once the tool vanished, their performance plummeted. Many abandoned the remaining questions altogether.
The experiment was replicated with a larger cohort of 670 participants, producing the same pattern: an initial lift followed by a steep drop in both accuracy and willingness to persist. A final round swapped math for reading‑comprehension questions, yet the outcome remained unchanged. The researchers concluded that reliance on AI can erode the very cognitive stamina it initially seems to support.
"We find that AI assistance improves immediate performance, but it comes at a heavy cognitive cost," said Rachit Dubey, an assistant professor at the University of California and co‑author of the study. "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. People’s persistence drops."
Dubey warned that rapid AI integration in schools could produce a generation of learners who lack confidence in their own abilities, potentially stifling innovation and creativity. The authors likened the phenomenon to the "boiling frog" effect, where gradual exposure to a stressor leads to a slow erosion of motivation that becomes hard to reverse.
The study also noted a modest positive finding. Participants who used the chatbot for hints or clarification fared better after the tool was removed than those who relied on it to generate full answers. This suggests that limited, supportive AI use may be less damaging than full dependence.
While the research has not yet undergone peer review, its authors stress the urgency of understanding AI’s broader impact on cognition. The findings echo earlier observations of "AI brain fry," where workers who lean heavily on automated tools end up working longer hours and experiencing greater fatigue.
As AI technologies become more embedded in everyday tasks—from coding to brainstorming—this study adds a cautionary note. Immediate gains may be tempting, but the long‑term cost to independent thinking and perseverance could outweigh the short‑term benefits.
