The Flynn Effect is what we call the phenomenon of IQ rates going up across the board over the last 75 years, it's established as true yet nobody will claim that we all got genetically smarter.

- darawk 4y agoThat is true, and an important criticism of IQ as a measure in general. However, it's not clear that the Flynn effect is relevant to the conclusions of this study. Why do you think it is?
- woooooo 4y agoIt was more of a general rebuttal to the idea of "the numbers move so it must be genetic". The study you linked was interesting but adopted kids are an abnormal case to begin with and the effect indicated was tiny compared to societal things IMO.
- darawk 4y agoThe effect size was about a third of a standard deviation, which isn't huge, but isn't trivial either. Assuming it's true and genetically determined, that could have significant effects at the aggregate level. However, a ray of hope in the study is that, even if you take its confidence intervals at face value (I don't), then there is quite a bit of room for improvement in the nurture sphere, as the black/white IQ test gap is generally much larger than this when not as carefully controlled as this study.
