>> What Flynn said in that article goes right along with his theory of education increasing IQ by 60 points over the last 120 years, Flynn has "proposed" various explanations. IQ, by definition, doesn't change over time. But the ability to perform tasks on IQ tests may. A person may get better at test-taking. And their exposure to computers and other technologies may matter. The same person may score higher in 2013 on a test from the year 2003 than they did in 2003. This does not signify a higher level of intelligence. Only that they have absorbed more knowledge -- probably because there is more knowledge available to be absorbed. Flynn's analysis is misleading at best. Your understanding of it is even worse. Nothing here explains why, as Alistair pointed out, in some places this effect is not present or only minimally so. The "IQ relative to other years' testing" has found persons in many countries actually do score lower over time. These include places like Norway and all over Europe -- where that is not an intuitive outcome.

You are fooling yourself. The Telegraph article was from 2009. You have often stated that you believe in science and statistics. If so, read the PNAS article referenced below. A 2018 study published by the National Academy of Sciences confirmed the decline. The results show that those born in 1991 scored about five points lower than those born in 1975, and three points lower than those born in 1962. The turning point for the Flynn effect occurred for the post-1975 birth cohorts, equivalent to 7 fewer IQ score points per generation. pnas.org There is no evidence to support your statement the "the kids are getting smarter".
