I suppose I'll be the one to post the canonical recap of this concept: https://m.youtube.com/watch?v=YwZ0ZUy7P3E

There is a reason Idiocracy has been described as a documentary :)

...because the people describing it that way are ironically ignorant of world statistics?

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?

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.

you are joking right?

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.

That would make sense - immigrants usually aren't native speakers. Given that most IQ tests have portions that rely on linguistic ability... So it's not that their IQ is lower - it's that they test lower.

I am curious as to the distribution of jobs amongst immigrants.

What percentage of immigrants are grad students or people with high tech jobs. I don't know, and I'm genuinely curious.

It seems like with just a bit more effort the authors could have made a stronger case for their theory that aging is significantly impacting IQ scores by comparing IQ scores among people of the same age (e.g. 20-30 year olds) from decade to decade. They could also look at how IQ changes over a lifespan; there must be some within-subject data available where the same people took an IQ test when they were 60.

You only do enough research to get the p values just right so you can publish. Scientists are not rewarded for more investigations that might weaken their theory.

P-hacking or how to sell your scientist soul.

Have seen any scientific IQ test other than fakes ones on internet?

The portions are well discrete. IQ test has nothing to do with linguistics ability (at least we don’t know it) and most of IQ test don’t require you to read or write anything.
