Article is paywalled. How about this for a hot take, based on the title alone: there is an overlap of an IQ boosting effect from environment (better nutrition, health care etc.) and an IQ depressing effect from genetics (e.g. increasing years of education depressing fertility of high-IQ people, or increased mutational loads from all those carcinogens California tried to warn us about, or whatever). For decades, the IQ boosting effect dominated (resulting in the Flynn effect), but now it's basically maxed out, and the IQ depressing effect drives the trend.
- bloak 8y agoArticle was not paywalled for me the first time I looked. As I recall, it claimed that the measured fall in IQ test results cannot be explained by genetics because the same fall was observed within particular families. In any case, the fall seems far too big to be explained by genetics, so probably it's caused by education, I would guess. There probably is a much smaller, perhaps not yet measurable, fall caused by genetics. I tried to submit an Economist article on that. (Can you see it under https://news.ycombinator.com/submitted?id=bloak https://news.ycombinator.com/submitted?id=bloak ?)
- dschuetz 8y agoIt appears that when an article gets many hits at a time a paywall is triggered. So, the title is clickbaity, then it gets submitted to HN, a few people read it, then suddenly it's paywalled. Right. Moving on, nothing to see here.
