IQ rates are dropping in many developed countries

These raw scores have been rising on a variety of standard IQ tests for over half a century. But current IQ tests are designed to measure core cognitive skills such as short-term memory, problem-solving speed and visual processing), and rising scores show that these cognitive capabilities can actually be sharpened by environmental factors such as higher-quality schools and more demanding workplaces. And while we might be able to compensate with skills besides intelligence, like determination or passion, in a world where IQ scores continue to fall — and where the drop expands to places like the United States — there’s also a bleaker scenario: a global intelligence crisis that undermines humanity’s problem-solving capacity and leaves us ill-equipped to tackle the complex challenges posed by AI, global warming and developments we have yet to imagine.
