Sami: Very good points, Thinking Mouse.
The majority of our immigration comes from Latin American, average present IQ 90-95, and from East Asia, average present IQ 100-107. This averages out to close to 100 as it is, if you look at those two groups in combination. And this doesn’t take into account the Flynn Effect (though, unfortunately, I doubt Mexican American Barrio culture, as it presently is, at least, is something that would do much to accelerate the Flynn Effect, sorry to say.
And we get smaller input from places like the Middle East, present average IQ 84-90, if Richard Lynn’s methods for assessing this are valid (highly questionable, at best). However, Arab Americans and Iranian Americans both have average incomes and average levels of educational attainment — both considered to be rough proxies for average IQ — than the White American average. So, it is clear, that within American culture (in stark contrast to the case with Europe) those groups seem to be Flynn-effected upward.
In short, I am unconvinced that our present immigration policy is dysgenic.
Instead of simply not being Flynn-effected, I would argue that barrio culture is actually IQ-impairing. I don’t have any evidence for that, but I can hardly think of a more aggressively, belligerently, arrogantly ignorant culture in the US. Even US Black culture is more educated and intellectual than US barrio culture. Isn’t that pitiful?
Latin America does NOT have an average IQ of 90-95. Most of the immigration is from Mexico, IQ 90. The rest is from Central America, IQ 85-90. Average IQ of Hispanics in the US is ~90. We don’t get that much immigration from East Asia. China is where most of it comes from, IQ 105. Combined together, you get IQ 96, but there are many more Hispanics, so that lowers it to ~93. At the end of the day we don’t know what the IQ of immigrants, legal and illegal, is in the US.
Hispanic IQ in the US is not undergoing any Flynn rises compared to Whites. It just stays at 90. Arab and Iranian IQ is not high, but in the US, they may be selected. Anyway, they appear much smarter than Hispanics here in the US, whatever their IQ’s are.
You have only to look at large Hispanic communities to see that the IQ is not the same as a nearby White town. This Hispanic city here may have an IQ of 93. I came from a nearby White town which probably had IQ of 100. The differences were so stark it was shocking. So you can see that even seven IQ points at a macro scale like that has a huge effect on the intelligence of a city. You can really see IQ differences when you look at whole cities full of people of different IQ’s.
US IQ has always been 100. In recent years it has fallen to 98. How did that happen?
