That's the short version in my opinion. Furthermore, when the Flynn effect was observed, sceptics weighed in and argued that the increase in scores could be a temporary reflection on the population’s adaptation to test-taking strategies and test familiarity, or improved literacy rates even. There has, however, been very little evidence concerning any continuity of the effect specifically into the present century. More recent studies indicate that the test results in Norway are more or less stable since the nineties [3]. Reverse Flynn effect? TITLE.

The Flynn effect: Smarter not faster. Although we concluded differences between the predicted scores reported earlier were consistent with a modest Flynn effect, these latter findings could also be interpreted as consistent with findings of a plateau or even reversal of the Flynn effect in this century (Dutton et al., 2016; Platt et al., 2019). The study followed up 500 volunteers born 1930–1932 (C30) and 502 born 1950–1952 (C50).

The N-weighted net of these is a loss of -1.35 points per decade, suggesting an overall tendency towards decreasing IQ in the Netherlands with respect to these cohorts. The Flynn effect is a perplexing phenomenon for those who believe that IQ tests represent a true measure of human intelligence, as it would suggest that people today are in general considerably more intelligent than those of previous generations. Flynn himself does not believe this to be the case. Christophe Clavé. Reverse Flynn effect?

IQ scores are on decline, reversing the Flynn effect that saw scores rising at steady rate during 20th century. Using administrative register data with information on family relationships and cognitive ability for three decades of Norwegian male birth cohorts, we show that the increase, turning point, and decline of the Flynn effect can be recovered from within-family variation in intelligence scores.
