... and now I see your linked article made a similar point to my previous post.
From the article...
Researchers across the globe have been tracking an
apparent decline in human IQs, starting around the turn of the millennium. Theories abound as to why scores are dropping, but the smart money says our cognitive skills may have plateaued, teetering into an era of intellectual lethargy.
If you want to ascribe blame, look no further than this screen.
Cognitive researchers hypothesize that smartphones and smart speakers, autocomplete and artificial intelligence, Wi-Fi and runaway social media have conspired to supplant the higher functions of the human brain. In its quest for labor-saving tech, the world may be dumbing itself down.
(Me again: This could create some interesting inversions of Euro/US notions of where the smartest people are. It may soon be that they live in a lower tech village in Uganda or Papua.)
Ok, putting down my tablet....
