A new study claims to provide the first causal evidence that relying on AI to assist with cognitive tasks can rapidly impair users' intellectual abilities and willingness to persist through difficult problems. The researchers warn that the gradual erosion of these 'cognitive muscles' through AI dependency could lead to significant long-term challenges, likening the effect to a 'boiling frog' scenario.

Why it matters

As AI-powered chatbots and assistants become more prevalent in education, work, and daily life, experts are growing concerned about the potential for these tools to undermine core human skills like independent problem-solving, critical thinking, and perseverance. The study's findings raise questions about how widespread AI integration could transform people's self-confidence, work ethic, and capacity for innovation.

The details

The study, conducted by a team of researchers from institutions like UCLA, MIT, and Carnegie Mellon, involved experiments where participants were asked to complete math and reading comprehension tests. One group was given access to an AI chatbot assistant, while the other served as a control. Initially, the AI-assisted group performed better, but when the chatbot was suddenly taken away, their problem-solving abilities and willingness to keep trying declined sharply. The researchers believe this 'boiling frog' effect could accumulate over time, leading to significant challenges down the line.

  • The study has not yet been peer-reviewed.
  • The experiments were conducted in 2026.

What they’re saying

“We find that AI assistance improves immediate performance, but it comes at a heavy cognitive cost. 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.”

— Study authors

“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. This is analogous to the 'boiling frog' effect, where each incremental act feels costless, until the cumulative effect becomes overwhelming to address.”

— Study authors

“People's persistence drops. 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.”

— Rachit Dubey, Assistant Professor, UCLA

What’s next

The researchers are planning to expand their research into longer-term experiments to further understand the potential cognitive impacts of widespread AI integration.

The takeaway

This study raises serious concerns about the long-term effects of AI dependency on human cognition, warning that over-reliance on these tools could undermine core skills like problem-solving, critical thinking, and perseverance, potentially transforming people's self-confidence and capacity for innovation.
