earlier this week, an article was posted to hn about IQ scores having fallen since the 70s, at https://medicalxpress.com/news/2018-06-iq-scores-1970s.html https://medicalxpress.com/news/2018-06-iq-scores-1970s.html one key takeaway: A British team recently found IQ score results falling by 2.5 to 4.3 points every decade since approximately the end of the second world war. And this past December, another group from the U.S. found that children who grew up eating a lot of fish tended to have higher IQs—and they slept better, too, which is another factor involved in adult intelligence levels. Notably, children in many countries in the modern era eat very little fish. Also, "a dozen mercury-containing vaccines", how much mercury is that? Is this like telling me not to fly because I get 1000x more radiation from it than eating a banana? Comparing the miniscule to the infinitesimal makes neither large.
