Or maybe it's because, somewhat depressingly, IQ is highly hereditary, as research has shown for decades and new gene research is currently confirming, and people with lower IQs tend to have more children.

#92Mexico has an average IQ of ~90. Perhaps displacing large swaths of white america wasn't such a great idea.

Let me take a guess. Comparatively low immigration rate. Hardly accept any refugees (28 individuals accepted by Japan in 2016). Be able to support yourself or be (quite literally) kicked out. High barriers to citizenship.
Are you serious? Let me ask you how many of immigrants are grad students or prople with high tech jobs? Is it one of the stupidest thing to say drop in IQ is connected to immigrants! It is greatly disappointing to see this kind of nonsense in HN which is kind of home for many hackers and programmers. Hearing these kind of stupid ideas in C-Span? Who cares? But HN, that shows how low our societies has become.
What portion of grad students and high tech jobs are Mexican immigrants? Very few.
Conflating immigration from high IQ populations like China, Korea, and Brahmin India with South American immigration is just ridiculous.

What percentage of immigrants are grad students or people with high tech jobs. I don't know, and I'm genuinely curious.
There are statistics on education level. For example "Share of the population aged 25-64, by educational attainment level, by place of birth and by sex, EU-28, 2016". http://ec.europa.eu/eurostat/statistics-explained/index.php/....

Now let's say that you make it difficult (either deliberately or due to language barriers) for individuals in the left-most part of that graph to stay. What happens long term? I don't know.

And connecting the two dots too loudly makes you into a monster.

But most people back then didn't go to university. And the OECD compares across 23 developed nations. Though, in my opinion , education quality has gone down. In France, 2010ish?, in my last year of high school (in one of the best parisian high school) there was a boy who couldn't read aloud a text without stumbling. I don't know if this would have happened in the past. But back then only 20k students reached that st…
>Though, in my opinion, education quality has gone down. What would you think if I told you I graduated in the 1990s and I felt the same way? Where would that put you? >there was a boy who couldn't read aloud a text without stumbling. There could be other reasons for that, like fear of public speaking.
Maybe you were in a pessimistic period in your life and I am the same way now.
He didn't fear much. He was a bully.

He didn't stutter when speaking. He just couldn't read as fast as he was talking so he had to stop every few syllables. In other words, he was 17 and couldn't read fluently. But he wasn't stupid. He was quite conscientious about his side business and bookkeeping. ps: I stuttered when I was a child.
>He just couldn't read as fast as he was talking so he had to stop every few syllables. Is that your professional medical opinion?
No. But it's the opinion of someone who spent 6 to 8 hours a day during three years with the person in question. He couldn't read. When he read in his head he mouthed the words.

#100I can’t access the original study (sci-hub too slow), which countries are affected by the effect and which aren’t? It would be interesting if China, Japan, Korea aren’t affected while Western countries are.
Maybe I'm being really naive here but (other than all being Asian countries) what attributes do China, Japan, and Korea all share that Western countries don't?
Lots?
For one, they are all ancient civilizations -- most western countries aren't.
Second, they have different value systems (more collective than individualistic).
Third, they have different nutrition and culinary preferences.
Fourth, they have differences in lifestyles.
Fifth, they are more homogenous than a lot of western countries like the US, Britain and France, with much smaller (percentage wise) immigrant populations.
In most aspects, a place like Chicago and a place like Tokyo might as well be on different planets.
