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.
I am curious as to the distribution of jobs amongst immigrants.
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.
The most widely used IQ test has explicit verbal testing.

Verbal testing is different than spatial ability testing? Do you see the logic? Verbal testing is separate skills. And spatial skills are different too.
>The most
Completely false.
> Verbal testing is different than spatial ability testing? Do you see the logic? Verbal testing is separate skills. And spatial skills are different too.
Because I do have the answer. The article asserts that average IQ is falling. It does not indicate that only, e.g., spacial ability is falling. Given that verbal is a direct component in its own right (as well as a factor in other areas due to comprehension and communication), it is reasonable to state that verbal is likely a factor in the falling average IQ.
> Completely false.
It's not completely false. WAIS is extremely widely used. It's not simply the most frequently used IQ test[1]. It's one of the most frequently used clinical assessments in general.
You're just asserting things you want to be true. If you disagree that WAIS is the most common clinical IQ test, then provide some info on what you believe is more common. Otherwise your claims are clearly without merit.

You gave your answer here:
>You're just asserting things you want to be true.
Article states the IQ has been dropped. We don’t knew which part, we don’t know why, we don’t now how much.
You are just saying “immigrants have problem with language” -> “immigration causes this drop”. This is total nonsense. We don’t know. Maybe there is the change is related to influence of smartphone and etc. has you calculated how much immigrants we accepted? How much our IQ has been dropped? Does the math makes sense with these numbers or there should be other factors?
We don’t know. Do you understand what “we don’t know” means?
I think the best answer is what you gave to yourself.
>You're just asserting things you want to be true.
I never said anything like that. My comments have addressed nothing except your claim that linguistic skills are irrelevant in IQ tests, a claim which you've clearly based on nothing.
> This is total nonsense. We don’t know. Maybe there is...
No one said that this is the cause. Someone proposed it as a potential reason. Someone else proposed that if so, the language barrier might be the issue. These are just hypotheses. They might be right. They might be wrong. They might be contributing along with many factors. The fact that "we don't know" doesn't mean it's unreasonable to discuss, though.
> Do you understand what “we don’t know” means?
You should ease up on the condescension toward others. You're clearly not even reading comments at this point. You're just ranting and your arrogance is unwarranted. I don't know why you're so upset that someone would suggest that immigration might impact a nation's measured IQ, but if you can't engage civilly, maybe you shouldn't engage.
(By the way, it did not escape my attention that you again failed to provide any sources that back up your claims about IQ tests. You seem to demand a much higher standard of evidence from others than you demand of yourself.)
I asked for statistics and wanted a number. pointing ideas without any numbers is ridiculous. I am fascinated how much people can ignore what they don't like to see.
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.
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.
Depends on the country of entry and the country of origin.
The majority of latin America immigrants in the US, or African immigrants in France for example will be nothing like "grad students" and "high tech jobs".
>Is it one of the stupidest thing to say drop in IQ is connected to immigrants!
It's actually a pretty decent explanation. If different countries have different average IQs (which we know to be correct) and if the mass immigration is not of the "grad student" type (which we also know to be correct), then it's a good explanation, assuming there's no other factor that we neglected to examine. Remains to be seen if this is indeed the case or if there's another cause (or perhaps multiple causes).
>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.
You are ranting. This is not a reasoned argument against the parent's argument. This is what's anti-hacker and anti-science.
FYI the parent comment was not reasoned argument either. The notion of relation between education and IQ is questionable.
>It's actually a pretty decent explanation.
No it is not at all. Since it requires rigorous calculation and estimation of how much immigrants have come, what is their average IQ, how much drop we see in population and so many questions.
This is what “pointing finger without any evidence” looks like. I don’t understand why you would consider your approach scientific when I am the one basically asking and questioning all the moving parts.
Questionable based on ethical considerations is not the same as non-rational.
It's a very logical thing to consider. A mechanism for example would be that people with higher IQ also tend to succeed in completing more higher education degrees. The inverse is also possible, and it's also a perfectly valid thing to suggest and study. In fact it's studied e.g. in this paper: http://www.pnas.org/content/109/2/425.full.pdf
>No it is not at all. Since it requires rigorous calculation and estimation of how much immigrants have come, what is their average IQ, how much drop we see in population and so many questions.
That's what's required to get a full result. It's not however required for merely putting forward the argument as a possible explanation, or for judging whether the argument is rational or not.
It seems that your concerns are more tied to a priori axioms and emotional resistance than actual methodological issues in the questions.
This is the difference between you and me. Before putting an argument forward I would evaluate it or at least calculate it a little bit!
>It seems that your concerns are more tied to a priori axioms and emotional resistance than actual methodological issues in the questions.
Why would you say that? The only thing i wanted was a little bit evidence and calculation! And it is funny in your nonsense world I am the emotional one here!
Did this difference emerge very recently?
Because for someone who claims that, it seems bizarre that you entered this thread by stating: "Let me ask you how many of immigrants are grad students or people with high tech jobs?"
How is that more "evaluated" or "at least calculated" that what the parent wrote? Where were the numbers that go with this?
You then went on to give non-arguments combined with non-facts: "Is it one of the stupidest thing to say drop in IQ is connected to immigrants!"
And on with the non-arguments + non-facts: "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."
or not? And asking question or pointing calculation flow in one argument has nothing to do with evaluating your idea before puting forward.
Seriously, Why do you keep repeating yourself!
