No, it's not just you — people really are less smart than they used to be.
As the Financial Times reports, assessments show that people across age groups are having trouble concentrating and losing reasoning, problem-solving, and information-processing skills — all facets of the hard-to-pin-down metric that "intelligence" is supposed to measure.
These results, the FT reports, are gleaned from benchmarking tests that track cognitive skills in teens and young adults. From the University of Michigan's Monitoring the Future study documenting concentration difficulties of 18-year-old Americans to the Programme for International Student Assessment (PISA) that measures the learning skills of 15-year-olds around the world, years of research suggest that young people are struggling with reduced attention spans and weakening critical thinking skills.
