I’m glad there are official studies being done to document this, but also it’s vary obvious if you’ve spent any time around people in the past few years. The degradation of critical thinking and research skills is highly tangible and disturbing. Any country that isn’t addressing this significant intelligence gap is going to have an entire generation (or more) of brain-drained, unskilled citizens that can’t meaningfully contribute to the national workforce. For western countries that have already surrendered most of their manufacturing and innovation overseas, this will be even more devastating.
