We have remarked upon a number of cases in which movement from a Third World country to a 1st World country results in an IQ gain for the Third Worlders in the 2nd generation. The results will be listed below and the data can be found by searching the archives on the blog (I’m too weary to look them up and link them); anyway, regular readers have already read the original pieces.
Pre-West Post-West* IQ Gain Jamaica 71 86 15 US Blacks** 72.5 87 14.5 India 83 94 11 Mexicans 85 95 10 Philippines 86 93.5 7.5 Chinese 97.5 105 7.5 Japanese 97.5 105 7.5 Morocco 84 89 5 Post-West refers to second generation. The figure for US Blacks is their theorized genetic IQ based on African/Caribbean scores plus the White % in US Blacks.
The Filipinos, Mexicans and US Blacks went to the US. The Indians and Jamaicans went to the UK. Moroccans went to the Netherlands. Gains ranged from 5-15 points in the second generation. This is above and beyond the Flynn gains already taking place, and probably ongoing in most of those countries.
The gains are where these ethnic groups actually closed the gap with Whites by the amount of the gain in the third column. Looked at in another way, these groups closed the gap with Whites by 5-15 IQ points in a single generation. In addition, there are ongoing Flynn gains occurring alongside these migration gains, but they are not showing up as IQ gains because the Whites are pacing and matching the others precisely.
The Filipinos’ IQ’s are 13 points below the 106.5 for Chinese, Japanese and Koreans, giving them an IQ of 93.5. This is a full 7.5 point Flynn rise over the 86 IQ in the Philippines just from moving to the US.
However, Filipinos are starting to come close to US Whites in occupational success due to extra-IQ factors. This is the part that is very interesting. In other words, despite IQ’s that are a full 6.5 points below that of US Whites, Filipinos are beginning to match Whites in occupational success. This is because Filipinos have extra-IQ factors above and beyond the extra-IQ factors that the Whites have.
The extra-IQ factors are simply postulated, but they may have to do with “introversion.” Along with that, we may find self-discipline, orderliness, a strong work ethic, punctuality, ability to follow orders, putting in extra time on the job, cautiousness, ability to self-train and self-teach, etc. All of these things will tend to increase with introversion and probably decrease with extroversion.
As Whites are considerably more extroverted than Filipinos (Asians), Filipinos will probably score better on many extra-IQ factors than Whites, with the end result being that the extra-IQ factors allow the Filipinos to overcome an IQ deficit and nearly reach parity with Whites on the job.
The Filipino figures come from James Flynn’s book, Asian Americans: Achievement Beyond IQ. In the book, Flynn shows that the second generation of Chinese and Japanese made not only remarkable IQ gains against US Whites, going from the 97.5 IQ of their parents to the 105 IQ of the second generation (and passing Whites at the same time) but they were on average working at positions that were 10-20 points above where they should have been working based on their IQ’s.
The question arises, What about US Blacks? The fascinating thing about African-Americans is that they have an unexplained 14.5 IQ rise above and beyond what ought to be their genetic IQ.
The hereditarians have never been able to explain this well. On of their feints is to say that IQ in Africa (= 67) is artificially lowered by malnutrition. Well, possibly, but then why is Black IQ about the same in the Caribbean (= 71)? Keep in mind that Caribbean Blacks often have a small amount of White in them (Jamaicans have 9%). So it does look like genetic Black IQ is indeed around 70.
That means they are mentally retarded, but we have already had the discussion about this on the blog. The commenters and I agree that Blacks in Africa and the Caribbean with 70 IQ’s are not retarded in the sense that a White person with a 70 IQ is. In this sense, the tests don’t seem to measure Black intelligence properly. On the other hand, while they are not retarded, I don’t think that your average 70 IQ African is all that intelligent.
I’m getting at a couple of things here. First of all, can Blacks make use of these extra-IQ factors to at least overcome their 13.2 point IQ deficit with Whites in the sense of at least performing above their predicted IQ level on the job? Keep in mind that in order to do that, Blacks would have to display these extra-IQ factors above and beyond the level of the Whites. Since Blacks are the most extroverted race of all, this seems dubious.
On the other hand, we have a large up and coming Black middle class that is itching for success. By dutifully emphasizing the extra-IQ factors listed above, upwardly mobile Blacks will at least be able to perform above their IQ level on the job.
On curious area that no one considers is personal skills. There seems to be a lot of evidence that Blacks are more socially adept than Whites. In jobs where social intelligence and skills are highly valued, conscientious Blacks may be able to outperform their White co-workers and at least partially close the occupational success gap with them.
Second of all, it seems possible that Africans moving to the West may experience ~15 point IQ rise in the second generation. It hasn’t showed up yet, but no one has looked for it. So the 67 IQ Africans by the second generation should be at IQ 83. It’s not that great, but there are more or less functional countries with 83 IQ’s. There aren’t that many with ~70 IQ’s. To the extent that Africa can mirror the environment of the West in Africa itself, they won’t even have to come here.
This is groundbreaking work that is receiving very little ink, less than it deserves. At the very least, rising IQ with migration and extra-IQ factors show that neither is IQ set in stone, nor is it destiny.
