IQ tests: are humans getting smarter?
Published: May 5, 2021

While IQ test results have been increasing for some time, research
suggesting a “reverse Flynn effect”, indicates this upward trend may
now be slowing. A Norwegian study, for example, found that men born
before 1975 showed the expected positive “Flynn effect” of a three
point gain for each successive decade. But for those born after 1975,
there was a steady decline in IQ. This amounts to a seven point
difference between generations – with average IQs having dropped by
around 0.2 points a year. Other studies carried out between 2005 to
2013 in the UK, Sweden and France have also shown similar results.

I am a bit suspicious that the internet might be having a bad effect.

have to do much thinking for themselves.
