# Did the average IQ score in France decline in recent decades? - Tags: intelligence - Score: 18 - Views: 4,094 - Answers: 1 - Asked by: user12079 (409 rep) - Asked on: Aug 26, 2017 - Last active: Aug 5, 2019 - License: CC BY-SA 4.0 --- ## Question We all know about the [Flynn effect](https://en.wikipedia.org/wiki/Flynn_effect), that states that it has been the case that in the recent past the IQ scores in developed countries have been steadily increasing. The reasons seem to be related with less hunger, less poverty and violence and increased literacy rates. I have found here and there, though, studies that seem to suggest that as for the last decades, the Flynn effect may not actually be happening in countries in Europe such as France, UK or the Netherlands. Such a study can be found here: [http://www.sciencedirect.com/science/article/pii/S0160289615001221](http://www.sciencedirect.com/science/article/pii/S0160289615001221) > Dutton and Lynn report secular declines in Fullscale IQ evaluated using WAIS of four points a decade in France between the years 1999 and 2008–9. I would like to know if such studies have any kind of credibility. --- ## Accepted Answer — Score: 25
