Hmmm I wonder if an increase use of videogames paired with a decrease in the amount of time parents can spend communicating with their children might be related.
Note that over the last 30 years it's vastly transitioned from one parent staying home raising children to both parents working.
> A study of Norwegian military conscripts' test records found that IQ scores have been falling for generations born after the year 1975, and that the underlying cause of both initial increasing and subsequent falling trends appears to be environmental rather than genetic.
In 2019, a group of researchers from the University of Oslo published a study that found no evidence of a decline in IQ scores over time in Norway, despite claims of such declines in other countries. The researchers argued that the methodology used in previous studies may have contributed to false conclusions about declining IQ scores.
In contrast, a group of researchers from the University of Amsterdam published a study in 2018 that reported a decline in IQ scores in the Netherlands over the past several decades. The researchers suggested that changes in educational systems, such as increased emphasis on testing and memorization, may be contributing to the decline.
Made me pretty skeptical of the FE literature.
