The shift from reading to consuming video content may have diminished human intelligence, research finds
Human intellectual abilities such as reasoning and problem-solving are diminishing, possibly due to increased exposure to visual media, the Financial Times (FT) has reported.
Human intelligence appeared to peak in the early 2010s and has been in decline since, the FT added, citing PISA, an international benchmarking test for 15-year-olds that includes reading, mathematics and science, and adult cognitive evaluations.
The reported trend comes amid a rise in artificial intelligence (AI) which, by some estimates, may surpass human IQ in a matter of years.
The recorded spike in the share of high school students who reported difficulties in PISA tests coincides with a broad change in people’s relationship with information, such as the transition away from reading and towards visual content, the publication explained.
While active, intentional use of digital technologies can often be beneficial, being passively exposed to infinite content on social media coupled with frequent context-switching has been shown to negatively impact attention span, memory, and self-regulation. The documented decline in reading among Americans reportedly comes alongside a decrease in numeracy and other forms of problem-solving in most countries.
Human intellectual capabilities, such as critical thinking, have also been impacted by generative AI, according to recent research by Microsoft and Carnegie Mellon University. Outsourcing thoughts to AI leaves people’s minds “atrophied and unprepared,” which can lead to “the deterioration of cognitive faculties that ought to be preserved.”
Companies and governments have poured billions into AI research, focusing on areas such as machine learning, natural language processing, and automation. Tech giants like Google, Microsoft, and OpenAI have introduced increasingly sophisticated models, such as ChatGPT and Gemini, capable of performing complex cognitive tasks.
