Data compiled by The Financial Times found that humans are getting ‘dumber’.
The analysis looked at Europe’s Organisation for Economic Co-operation and Development (OECD).
The OECD administers the Programme for International Student Assessment, which looks at skills in 15-year-olds worldwide.
The assessment has consistently shown declines worldwide for years.
The declines affect attention spans, problem-solving skills and numeracy.
The assessment found that the intelligence of not only youths but also adults was declining.
The OECD’s Program for the International Assessment of Adult Competencies revealed declines among all age groups.
It found that the proportion of people unable to “use mathematical reasoning when reviewing and evaluating the validity of statements” has risen by 25 per cent worldwide.
In the U.S., it’s up by 35 per cent.
And while the 2020 COVID-19 lockdowns would seem like a factor in the decline, intelligence started declining in 2012.
A study from the University of Michigan also has revealed that more 18-year-olds are having a hard time concentrating, thinking or learning new concepts, with that number rising steadily since the 2010s.
The study is called the Monitoring the Future study and has been conducted every year since 1975.
The data coincides with the rise in popularity of smartphones and social media, which likely has negatively contributed to attention span, memory and self-regulation.
The new research comes amid the rise of artificial intelligence (AI) capabilities.
According to research conducted 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.”
Last year, tech billionaire Elon Musk warned that AI could become smarter than humans in the next three years.
