Lead has been a major cognitive suppressant for a large fraction of the population.https://www.ncbi.nlm.nih.gov/pubmed/24853978
Scientists have been reporting a "reverse Flynn effect" as of recently -- a gradual decrease in average IQ. There are many possible causes (a lot of them benign), but new environmental factors are clearly a big suspect.

And here the same argument. Internet and gaming might be great and fun. But how much % of time consume now kids in doing stuff that does not bring about any knowledge improvement? Study that factor over time. 5 hours a day of Instagram and whatsapp does not make you smarter.
