How AI May Impact Human Cognitive Abilities
Exploring the Impact of Technology on Intelligence
Recent studies suggest that our reliance on artificial intelligence (AI) might be affecting our cognitive abilities. In 1941, children were asked to write about British authors using only their memory and knowledge. Today, AI tools like Google Gemini and ChatGPT can instantly provide these answers, sparking concerns about cognitive offloading’s role in declining brain power.
This isn’t the first time technology has raised alarms. Mobile phones and social media have long been criticized for affecting attention spans and navigational abilities. Now, as AI becomes our cognitive co-pilot, some experts warn it might be diminishing our intelligence.
Psychologist Robert Sternberg of Cornell University argues that generative AI already compromises human creativity and intellect. Studies show the “Flynn effect,” a global increase in IQ scores since 1930, has slowed or even reversed in recent decades. In the UK, the average IQ of 14-year-olds fell by over two points from 1980 to 2008.
Elizabeth Dworak from Northwestern University cautions against blaming AI entirely. Intelligence is shaped by many factors, such as education, pollution, and technology. “We can’t point to one thing and say, ‘That’s it,'” she explains.
While AI’s full impact remains uncertain, its role in diminishing specific cognitive skills is measurable. AI’s use in memory tasks has been linked to decreased memory capacity, much like neglecting physical exercise leads to muscle atrophy.
Critical thinking is at particular risk. Michael Gerlich of SBS Swiss Business School found a significant correlation between frequent AI use and lower critical-thinking skills, especially among youth. Similarly, a study by Microsoft and Carnegie Mellon University showed that regular GenAI use might hinder problem-solving abilities.
AI-generated content is often more compelling, making it crucial to maintain critical thinking. Wendy Johnson from Edinburgh University observes that students rely heavily on the internet for answers, potentially neglecting independent thought.
Research indicates AI helps individuals produce more creative ideas but results in less diversity across a population. Generative AI is replicative; it recombines existing ideas without generating breakthrough solutions. Sternberg emphasizes the need for human creativity to tackle global challenges.
Engaging actively with AI might help preserve creativity. Marko Müller from the University of Ulm found a link between social media use and creativity in younger generations, suggesting active engagement fosters idea-sharing.
Cognitive neuroscientist John Kounios warns of potential long-term effects of AI on our brains. Insights gained from AI lack the mental rewards of personal discoveries, which drive learning and creativity.
Researchers recently found that learning a second language delays dementia onset, highlighting concerns about AI-powered translation apps replacing valuable cognitive activities.
Sternberg urges a shift in perspective: ask what AI is doing “to us” rather than “for us.” Gerlich suggests fostering skills like critical thinking and intuition in educational systems to maintain human cognitive abilities.
