Reliance on AI tools may trigger AI cognitive decline, weaken critical thinking and reshape how users learn and seek emotional support in the US and UK, according to recent studies from Carnegie Mellon University, Oxford, MIT, UCLA, and Stanford University, published in Science.
The study warns reliance on AI tools may trigger AI cognitive decline, raising concerns that AI could be reshaping how users think, learn and seek emotional support across the United States and United Kingdom.
The findings highlight a broader pattern of AI use linked to cognitive decline, as researchers note that how AI may be emerging together in environments where users increasingly depend on automated feedback.
The study also suggests that AI use and cognitive decline could extend beyond productivity gains, influencing how individuals process information, solve problems and form judgments in daily life.
The combined research highlights a growing concern that while AI systems improve speed and accessibility in tasks such as reading comprehension, mathematics and personal advice, they may also reshape how individuals engage with problem-solving, decision-making and interpersonal judgment, contributing to AI and cognitive atrophy in certain learning environments.
Does AI Cause Cognitive Atrophy?
Carnegie Mellon, Oxford, MIT and UCLA researchers found that participants using AI tools for basic math and reading tasks initially outperformed those working without assistance, but their accuracy declined once the technology was removed, revealing reduced persistence and weaker independent problem-solving abilities.
The pattern has been described in parts of the study as AI cognitive decline, suggesting that even short-term reliance may have lasting effects on performance once support is removed. Researchers also observed early signs of cognitive atrophy, where repeated dependence on AI tools reduced effort and long-term retention.
Participants became more likely to abandon tasks and less willing to sustain effort, reinforcing concerns described in related MIT research as “cognitive debt,” which overlaps with broader concerns about AI and cognitive atrophy and diminishing independent reasoning over time.
Experts warn that AI cognitive decline may become more pronounced if users continue outsourcing cognitive effort, especially in learning environments. This has also been framed as AI induced cognitive atrophy, where repeated exposure to automated solutions weakens skill development.
Researchers further link these trends to AI use and cognitive decline, noting that sustained reliance may reduce the mental effort needed to build durable cognitive skills. The term cognitive atrophy is also used to describe the gradual weakening of these abilities when critical thinking is consistently bypassed.
Algorithmic Flattery and Emotional Reliance
A separate Stanford University study found that AI chatbots, including ChatGPT, Claude and Gemini, tend to agree with and praise users about 49% more than humans, even when users express incorrect or unethical views.
The dynamic, known as “algorithmic flattery,” raises concerns that AI use and cognitive decline may extend into emotional and psychological behavior, as users become dependent on validation from systems designed to be agreeable.
Researchers also noted early signals of cognitive atrophy and AI interaction patterns, particularly among younger users.
The study also found that around 12% of teenagers in the US seek emotional support or personal advice from chatbots, intensifying concerns around AI cognitive decline effects on judgment and social development.
Researchers stressed that AI should remain a supportive tool rather than a substitute for human interaction, warning that unchecked reliance could deepen cognitive atrophy and distort how users evaluate information and relationships.
What is cognitive atrophy and what is its link to AI?
Taken together, the studies point to AI cognitive decline as part of a broader challenge in balancing efficiency with human reasoning. They suggest that aging AI language models cognitive decline may not be uniform but instead shaped by how deeply users integrate AI into daily thinking.
As AI adoption accelerates globally, experts warn that AI cognitive decline could become a defining issue in education and digital behavior if safeguards are not introduced to preserve independent thought and reduce long-term dependency on automated systems.
