Latino Intelligence - Data from the New Immigrant Survey

A few weeks ago Steve Sailer called attention to the New Immigrant Survey which, among other things, gave the children of immigrants to the United States four subtests on the Woodcock Johnson III Tests of Achievement battery. Steve suggested that some enterprising blogger try to calculate the IQ scores of Latino immigrant children based on these subtests. Thanks to my work, which provides me access to SAS, and a friend of mine who provided me with the WJ III Compuscore and Profiles Program 2.0., I am that blogger!

The four subtests given to Latino immigrant children were letter-word identification, calculation, passage comprehension, and applied problem solving. Standardized scores for each subtest fall on the same metric as standardized IQ test scores: up to 200 points total, with 100 points being the mean and a standard deviation of 15. I suspect that each of the four subtests correlates fairly strongly with g (though I will leave it up to people better-versed in the literature than I to argue over which of the four correlates with g the most strongly), so providing the standardized mean scores for Latino immigrants by age for each of the subtests, as well as the cumulative averages, by age, for all of the subtests, should give us some idea as to how much human potential is flooding across our southern border.

But before I get to the good stuff, a couple of caveats. First, I filtered out all the children who scored a zero on any subtest, as I figured those children were among the many who didn't complete the tests for one reason or another. Second, the tests were given to about half of the Latino children in Spanish, and the other half of the Latino children in English. I display one table for the Spanish test results and one table for the English test results below. Interestingly, the patterns that arise are the same for both tests. Finally, this part of the New Immigrant Survey didn't have any variables specifying the children's country of origin, so these results are for all Latinos but, given immigration trends, are probably most applicable to Mexicans.

Without further ado:



Given that genotypic and phenotypic IQs correlate more strongly with age, the numbers for the 12 year olds are probably most representative of innate Latino cognitive potential. Note also that the children do well on the calculation subtest across age groups. Perhaps their Native American ancestry is giving them a boost on this section?

Finally, on a personal note, this will be my last blog post. I'm off to law school in a few months and won't have time to keep up the blog. Thanks to everyone for reading!

UPDATE: Steve Sailer asked if I have a control group to which to compare these children. I do, in the form of the 1,048 non-Latino children who took these tests and completed all four of them. Here are their scores, which show a similar pattern of declining achievement with age, although they tend to score a few points higher than their Latino peers:



Here are the cumulative scores for all three groups (Latinos given the test in Spanish, Latinos given the test in English, and all other immigrant children) side by side, for ease of comparison:

Holocaust Halved the Current Population of Jews

From Haaretz:
If not for the Holocaust, there would be as many as 32 million Jews worldwide, instead of the current 13 million, demographer Professor Sergio Della Pergola has written in a soon-to-be published article...

...In the article, to be published in "Beshvil Hazikaron," the periodical of the Yad Vashem Holocaust commemoration authority's school of Holocaust studies, he writes: This was the destruction of a generation, and what we are lacking now is not only that generation, it is their children and their children.

Amish Inbreeding

Razib has a post up explaining why brother-sister matings are so much more likely than cousin matings to result in severely genetically disadvantaged children.

This got me to wondering how inbred the Amish are. Though the religious group generally prohibits marriages between first cousins, the founding populations of the various Amish settlements were quite small. This is evidenced by the distribution of surnames. Over 50% of the Amish living in the nation's three largest Amish settlements, (Lancaster County PA, Holmes County Ohio, and Elkhart-LaGrange Counties, IN) have one of five surnames. In Lancaster County, a full 25% of Amish have the last name "Stoltzfus." In Holmes County, OH and the Elkhart-Lagrange settlment, 25% or more Amish have the last name "Miller."

At least one study has been done to ascertain the inbreeding coefficient among Lancaster County Amishmen. From John Hostetler's Amish Society:
Of the 1,850 Amish couples in Lancaster County, it was found that all but 3 were related. The inbreeding coefficient was about the equivalent of each couple being more closely related than second cousins. Although there is a conscious effort to avoid close marriages, about 250 couples were found to be second cousins. Some were second cousins several times over. Two couples were first cousins once removed. Multiple distant relationships, such as quadruple second cousin marriages, also occur.
Conversions to the Amish faith are extremely rare, as the Amish don't evangelize and, a certain romanticism aside, their way of life isn't that attractive. But most Amish congregations don't have to recruit non-Amish people to diversify their gene pool. A more practical tactic would be for each Amish congregations to increase the number of outside Amish congregations with which it is "in fellowship," - meaning each group's children are free to date the other group's. This may become more practical as the search for new land brings previously separated Amish populations closer together geographically.

Begley on Race, Sex and IQ

Sharon Begley over at Newsweek has a post up on the science of sex, race and IQ, in which she exhorts scientists to study the issue so as to be better equipped to argue against "those whose agenda is to prove women and blacks intellectually inferior." Note that it doesn't seem to occur to her that there may be those on the other side of the debate who have an agenda as well, nor that the legitimate aim of science is to uncover the truth regardless of whose agenda it may be seen to support.

She's selective with her information as well, stating that the black white IQ gap has narrowed in the past 30 years while neglecting to note that there is evidence the narrowing stopped in the 1970s.

Appreciating Plath, Part One: Ariel as Adumbratio

No poet's reputation has suffered from the enthusiasm of her fans like Sylvia Plath's, whose groundbreaking poetry is ignored by men because they associate her with strident women's studies majors who have nothing interesting or original to say. Unlike many of her fans, Sylvia Plath was both interesting and original, as I hope the following series of posts will illustrate.

The key to understanding the strength of Plath's poetry is to understand what the psychiatrist Carl Jung meant when he said in "Man and his Symbols" that “the unknown approach of death casts an adumbratio (an anticipatory shadow) over the life and dreams of the victim.” To illustrate this phenomenon, he tells the allegedly true story of a friend’s 10 year old daughter who provided her father with a curious and unnerving Christmas present: a handwritten booklet containing a series of the girl’s strange and apocalyptic dreams. The relevant motifs of the dreams are listed as follows:

1. An “evil animal,” a snakelike creature with horns devours all the animals in the world, but God comes in through the four corners of the world and gives birth to all the dead animals, making them live again.

2. The girl ascends into Heaven, where pagan dances are being performed, then descends into Hell, where she witnesses angels performing good deeds.

3. A horde of small animals frighten the girl, one of which grows to a tremendous size and devours her.

4. A small mouse is penetrated by a worm, than a snake, then a fish, then a man, and then the mouse becomes a man.

5. The girl sees a drop of water as if through a microscope, and sees that it is full of tree branches. She knows this to somehow be the origin of the world.

6. A bad boy throws dirt at passers-by; in this way, all the passers-by become bad.

7. A drunken woman falls into water, then emerges clean and sober.

8. Somewhere in America – the girl was German – people are rolling on anthills being attacked by ants. The girl panics and falls into the river.

9. The girl is on a desert in the moon. She sinks so deeply into the sand that she reaches Hell.

10. The girl is confronted with a luminous ball, which she touches. Vapors emanate from the ball, and a man comes and kills her.

11. The girl is dangerously ill. Birds come out of her skin and cover her body entirely.

12. Swarms of gnats obscure the sun, the moon, and the all of the stars except one, which falls on the dreamer.

Jung went on to discuss the archetypal themes present in the girl’s dreams. Perhaps most importantly, Jung saw the first dream as an illustration of Apokatastasis, or divine restitution. The idea of restoration returns again in dream 7, where a drunken woman is seemingly baptized by her fall into the river and renewed. Images of apocalyptic destruction and archetypal images of creation occur separately in several other dreams. Apocalyptic destruction is most evident in dream 12, while dreams 4 and 5, portray the creation of humanity and the world, respectively. Dream 4 is particularly interesting in that the mouse’s original penetration by the worm, and then by subsequently higher life forms, seems to reflect human embryonic development, during which the individual sheds vestigial characteristics such as gills and a tail as he or she develops.

In total, Jung identified the following themes in the girl’s dreams: death, restoration, the creation of the world, the creation of man, and the relativity of values. Jung claimed that upon reading these dreams for the first time, he was overcome by “the uncanny feeling that they suggested impending disaster,” given that their symbolism was “the opposite of what one would expect to find in the consciousness of a girl of that age.” Rather, they are all themes Jung identified as particularly important to those approaching their life's end. As it so happened, at least according to Jung, the girl fell ill unexpectedly and died about a year after giving her father this unique Christmas gift. Jung posited that her dreams were visions conjured by her unconscious mind as it processed the shadow of her impending death.

Reports of presentiment are common in literature. Emily Dickinson described it as “that long shadow on the lawn/ Indicative that suns go down/ The notice to the startled grass/ That darkness is about to pass.” Interestingly, she seems to have anticipated Jung’s description of the phenomenon as a shadow cast backwards in time by an imminent and catastrophic event. Percy Shelley allegedly saw his doppelganger in the weeks leading up to his death, and John Donne is said to have seen his wife’s doppelganger on the night their daughter was stillborn. Were these mere stories dreamt up by men who, after all, lived with one foot in the world of the fantastical? Or were they perhaps visual hallucinations triggered by both men’s subconscious realization of impending catastrophe?

We should begin our consideration of Sylvia Plath's poetry with Ariel, the title poem of the book that posthumously made her name. The poem is short enough to warrant posting in its entirety.

"Ariel"

Stasis in darkness.
Then the substanceless blue
Pour of tor and distances.

God's lioness,
How one we grow,
Pivot of heels and knees! -- The furrow

Splits and passes, sister to
The brown arc
Of the neck I cannot catch,

Nigger-eye
Berries cast dark
Hooks ----

Black sweet blood mouthfuls,
Shadows.
Something else

Hauls me through air ----
Thighs, hair;
Flakes from my heels.

White
Godiva, I unpeel ----
Dead hands, dead stringencies.

And now I
Foam to wheat, a glitter of seas.
The child's cry

Melts in the wall.
And I
Am the arrow,

The dew that flies,
Suicidal, at one with the drive
Into the red

Eye, the cauldron of morning.

On the surface, Ariel is about a horseback ride where rider and horse merge into one heroic entity which breaks up, like a satellite entering the Earth’s atmosphere, as it gallops into the setting sun. In truth, it is an illustration of the poet's own destruction and, following her shedding of "dead hands, dead stringencies," heavenly restitution. Its incomparable conclusion is best described as death by incineration tinged with religious sentiment--for what is the sun but paradise, a light too pure for flesh to withstand? But read the final lines again, and one sees that the image is also one of conception. “The dew that flies suicidal” calls to mind semen hurling itself toward its own oblivion into the egg, here represented by the “cauldron of morning,” i.e. the feminine vessel of new life. Thus, in Ariel, death and conception are the same event, as the rider’s fiery incineration makes possible her heavenly rebirth.

In fact, the theme of Apokatastasis is present in nearly all of Plath's most famous poems, with perhaps two exceptions that will be discussed in a later post. Consider Plath's poem Fever 103°. Like the girl’s dream sequence as described by Jung, this piece contains a journey to both Heaven and Hell, apocalyptic imagery, and the themes of baptism and - once again - divine restitution. The poem begins with the following lines:

Pure? What does it mean?
The tongues of hell
Are dull, dull as the triple

Tongues of dull, fat Cerebus
Who wheezes at the gate. Incapable
Of licking clean

The aguey tendon, the sin, the sin.

The choice of Cerberus is not incidental, for the speaker then descends into a personal, fiery Hell where waves of fever are depicted as the radioactive fires of Hiroshima, “greasing the bodies of adulterers and eating in.” Where the young girl witnessed gnats blocking out the sun, moon and stars in her dream, Plath - who came of age in the decades after World War II and thus had a different, secular mythology to draw on - describes her state with images of atomic warfare. And yet, the poem’s overall theme is one of restitution, not punishment. In Plath’s own words about the piece during a BBC reading, “The fires that punish become the fires that purify.” This poem’s turning point occurs in the following three stanzas:

Three days. Three nights.
Lemon water, chicken
Water, water make me retch.

I am too pure for you or anyone.
Your body
Hurts me as the world hurts God. I am a lantern ----

My head a moon
Of Japanese paper, my gold beaten skin
Infinitely delicate and infinitely expensive.

The speaker, after suffering for three days and nights, seems to have vomited out the last of her sins, leaving her pure as God. “Does not me heat astound you,” she goes on to ask, “and my light?” But she is not only too pure for her audience; she is too pure for this fallen world:

“I think I am going up—
I think I may rise.
The beads of hot metal fly, and I, love, I

Am a pure acetylene
Virgin
Attended by roses

By kisses, by cherubim,
By whatever these pink things mean.
Not you, nor him

Not him, nor him
(My old selves dissolving, old whore petticoats)
To paradise.”

Thus the speaker, who earlier in the poem compared her illness to an adulterer’s divine punishment, is cleansed of her transgressions and restored to a pure, virginal state—a transformation which concludes with her ascent into Heaven, attended by angels and images of romantic love.

We come now to Plath's signature poem, Lady Lazarus. As in Ariel and Fever 103°, this poem documents the speaker's destruction and rebirth. Once again, as a part of the generation that came of age following World War II, Plath draws on the specifics of that conflict for her images, this time comparing her complete annihilation to that of the Jews in German death camps. Toward the beginning of the poem she describes her ressurected self as:

A sort of walking miracle, my skin
Bright as a Nazi lampshade,
My right foot

A paperweight,
My face a featureless, fine
Jew linen.

Jews processed in the German death camps came out as lampshades and linens. Plath's description of herself as possessing skin "bright as a Nazi lampshade" and a face like a "featureless, fine/ Jew linen" inform the reader that she has undergone something similar to the Nazis' unfortunate victims. Unlike them, however, she seems to have somehow survived, and is "a sort of walking miracle." Later in the poem, Plath describes the details of her self-annihilation, much as she does in Ariel and Fever 103°:

I am your opus,
I am your valuable,
The pure gold baby

That melts to a shriek.
I turn and burn.
Do not think I underestimate your great concern.

Ash, ash ---
You poke and stir.
Flesh, bone, there is nothing there----

A cake of soap,
A wedding ring,
A gold filling.

The Holocaust allusions are fairly obvious. The speaker has been reduced to a cake of soap, a wedding ring, and a gold filling--i.e., her body has been incinerated, the fat has been separated out from the flesh and all that remains is ash and the few parts of her that were gold and did not burn. But as in Ariel and Fever 103°, this destruction only sets the stage for the speaker's miraculous rebirth, described in the final stanzas:

Herr God, Herr Lucifer
Beware
Beware.

Out of the ash
I rise with my red hair
And I eat men like air.

The speaker has risen triumphantly from the ashes of her own cremation, her red hair calling to mind images of the phoenix, so powerful that she “eats men like air,” i.e. as if they were nothing. The poem’s title is itself an appeal to religious imagery, as Lazarus was the character in the Bible whom Jesus is said to have raised from the dead. And toward the poem’s conclusion, Plath calls out to both God and the Devil in warning. And yet the speaker, despite her references to a doctor earlier in the poem, seems to ressurect herself.

The details of Plath's life have led to her becoming a sort of feminist martyr. But her poetry is operating on an archetypal level - which is far deeper than that of political grievances. Thus, feminist interpretations of her work invariably sell her genius short. Plath was a sort of modern priestess whose exploration of the archetypal themes of death and restitution was paradoxically made possible by her own later suicide. The next post in this series will offer a Jungian interpretation of the men in Plath's poetry, notably in "Daddy" and "Death & Co.," and show that Plath's primary issue was not with men but with her own animus.

Hispanic Births Down in Arizona in 2008?

According to the Arizona Department of Vital Statistics, Spanish names such as Angel, Jose and Luis for boys have dropped in popularity from 2007 to 2008. Here are the ranks for boys' names for 2006, 2007 and 2008, with unambiguously Hispanic names in bold:

As you can see, Angel dropped from 1st place - where it has been since usurping Michael in 2005 - to 2nd place, Jose dropped from 2nd in 2007 to 8th place, Luis dropped from 7th to 18th place, while Jesus rose from 13th to 12th place.

Trends in girls' names are more difficult to track since a lot of popular girls' names like Isabella (most popular name in Arizona in both 2007 and 2008) could be Hispanic or Anglo. One welcome development worth noting, however, is that the girls' "name" Nevaeh (Heaven spelled backwards), which was the 18th most popular girls' "name" in 2007, dropped off the list entirely in 2008.

Anyway, this data suggests that the number of births to Hispanic moms in Arizona may have come down somewhat in 2008.
