Beware the website, it's a bit unstable and slow, but Spengler's worth reading. He's a former Reagan official, author, music critic, I-Banker, and Jewish "religious nationalist" supporter of Israel.

Of course, all of western Europe face much the same problem as France. But, the integration experiment looks ever more dubious even to conventional conservatives. To those of us who understand something of human biological diversity (HBD), it never even rose to the level of dubiety: it was a bad game at inception. Algerians, Moroccans, Somalis--and all the rest--are fundamentally discordant with Europeans at the biological substrate. Their intelligence levels and their personalities are quite different--and for purposes of what we recognize as productive civilization--markedly inferior. The Islamic factor is the enzyme catalyzing disaster out of this contrast of substrates. The conventionalists, Left and Right, only see this enzyme, Islam, and wonder how it could turn so vicious. They imagine themselves, in a fit of empathy, as converts to Islam, and perceive only the most reasonable aspects of the religion and culture. But, they are not North Africans nor Arabs nor Blacks. The enzyme reacts differently upon their substrate, not positively to be sure (or we might see rather more converts in the intellectual classes), but not disastrously either. Their attempt at empathy fails because they refuse The Knowledge of evolved differences between human groups. They lose themselves in evasive mazes of circular rhetoric and pathological social status competitions with their nihilist peers.
For a bit more of an HBD focus, this young Irish American woman writes well and extensively about the variety of human types:

Maths and Peoples
Only read this first link down to the quote I pasted beneath it:
http://www.vdare.com/articles/derbyshire-on-race-and-the-international-math-Olympiad
In the Supplement note I link at the bottom you see that 288 whites were up against 120 east Asians--but this is out of total populations of 1 billion and 1.7 billion, meaning 4 times as many competitors per million whites as Asians. What would the Asian average be if they put up 4 times as many as they did? Their average would decline. And blacks made only 41 out of about 900 million, 1/6 the white ratio, and took abysmal scores. Only 1 black scored in the top 260 (getting 17 out of 42), which is barely in the top half. Israel, with only 6 million Jews to work with, scored 18th place--only 3 smallish countries beat it: Singapore and Hong Kong, which only import smart people--and Hungary, which apparently just kicks ass. The American team has gotten more and more Asian and ever less Jewish and European in the last 20 years. Part of that is likely to be laziness among the latter groups. Asians took 19 out of the top 25 spots in this year's IMO. Yet 10 years ago they only got about 13 of 25. And 21 years ago, 11 of 25. It used to be the East European whites who pulled most of the weight for whites, but they've declined. This kind of super-high-IQ competition shows who are capable of making contributions and who aren't--though people cognizant of some basic history and not blinded by PC propaganda already have some idea.
Also, 9 times as many males as females made it into the IMO, yet the male average easily outpaces the female average, especially at the high end--and if you only look at the top 56 males (the top ninth) versus the 56 females, the score averages would be something like 33 to 10.5--yeah, so, thanks for playing girls. Only 1 female (Dutch) scored in the top 50, with a score of 29 out of a possible 42--the lowest score that still makes the top 50 cutoff. Last year only 1 (Jap) made it into the top 55, again at the minimum cutoff of 30 out of 42. Kind of reminds me of chess. Maybe there should be a female IMO. There definitely should be a black one, since they're much weaker than the females.:

So far as I can discover there have been only three black African IMO medalists in recent years: Chigozie Henry Aniobe of Nigeria with a bronze in each of the last four years; Puis Aje Onah of Nigeria with a bronze in 2010 and Isaac Jean Eliel Konan of Ivory Coast with a silver that same year. (Konan is rather light-skinned, possibly a mulatto.)
It’s a poor showing for a continent that has had established universities for decades.

Men's Rights and the Anatomy of Reaction
The Southern Poverty Law Center--a bunch of commies, jews, fags, and slags who've appointed and proclaimed themselves supra-Christian accusers of all evil in this world, holier than Jesus--think Chateau Heartiste and other assorted bloggers who operate from a realistic male perspective are evil, violent, malicious, mendacious. The "manosphere" is increasingly a branch of the "reactosphere" since (except the Christian reactionaries) both are grounded in reality--a reality which both political parties deny. When the leftist media comes down on you, it's a sign of headway. Also, a lesser light among the lefties just did a typically incompetent and inaccurate hit piece on Nick Land, the British philosopher who writes "Outside In." If you look at the map of Dark Enlightenment thinkers below, the connections are telling: with the exception of the Christians, all of these groupings revolve around some key aspect of reality that the Left denies or omits. Eight groups are listed, three count:
1. Techno-Capitalists,
2. Ethno-Nationalists,
3. Christian Traditionalists.
The relations among these three are predictably problematic. In theory the first and second or the second and third could come to terms in formulating a new dispensation--though difficulties abound. But, the first and third can only clash. Of course, 'twas was not always so. In centuries past capitalist and techno were not so tightly aligned, and capitalism itself is not an existential threat to Christian life and thought. Catallaxy is not anti-Christian. But, in these days of genetic engineering and evolutionary science, of neurological pharmacopeias and expanding machine intelligence--the technological underpinnings of twenty-first century capitalism represent conceptual catastrophes for Christian theology. In practice, it may be that two camps will coalesce--the Techno-capitalists with some sympathetic Ethno-nationalists, and the Christian Traditionalists with another contingent of Ethno-nationalists.
The future lies with the Techno-capitalists, whether they achieve more power in the West or not. The Christians cannot countenance the nano- and bio-tech revolutions. If empowered, they will crash the technoplex and render their realm geopolitically prostrate, as Land's "relentlessly self-enhancing" oriental realms scout new destinies. As to the Ethnos, though their present importance shines clearly through dusky leftist miasmas, what does the meaning of ethnicity reduce to when time comes that all humanoid inceptions aspire to become genetically engineered triumphs of power and aesthetics? Their perspective on reality would have to evolve so radically in face of such techno-leaps as to vanish their identity. Or, they could turn techno-denialist like the Christians. Either way, tide-taken relics of advancing storms, the time of the Ethnos draws down . Science has grown to the dimensions of a Demiurge--learned to throw lightning--and, cast under His dominion, the lesser deities will learn their place soon enough, or be new made in his image.

Known and Unknown Possibilities
http://infoproc.blogspot.com/2010/07/assortative-mating-regression-and-all.html
Note that the .5-.7 estimate is based on how much assortative mating has occurred among each parent's ancestors (more past assortative reproduction raises the estimate).
In the distance, thunderings and flashings of the overman:
http://infoproc.blogspot.com/2012/06/plenty-of-room-at-top.html
Average person=1000 deleterious mutations affecting IQ. Top hundredth of a percent IQ=900 such deleterious mutations.
And if we did a few dozen rounds of in vitro eugenic breeding (iterated embryo selection, IES), how much might this number be reduced? Of course, other genetic goals would receive some priority as well (eg, girls should be blessed with Marilyn Monroe's physical attributes). The principle limit on this technology may well be lack of knowledge of the phenotypic effects of various genes and gene-gene interactions. Some mathematical problems cannot be solved--experiments become necessary. Extrapolating the recent rate of progress, I suspect IES will be feasible within 10 years, though it will be suboptimal at least with respect to the gaps in our knowledge of which genes do what. And on the non-linearity problem, Hsu said, "Most of the genetic variation in intelligence is additive...fortunately for us linear effects still dominate the population variation* of quantitative traits. As any engineer or physicist can attest, linearity is our best friend :-)" Inescapable non-linearity, tragically, renders climate predictions invalid.
One problem with Hsu's analogy of this process with plant breeding: the ethical environment is completely different. Blind alleys in plant breeding are merely a waste of resources; in humans, they may entail great suffering.
But, the potential effects, as derived from such analogies, are spectacular: 32 SD increase in corn oil production per plant (an effort still making progress), an increase in flying speed of certain flies from 2.2 to 170 cm/sec in 100 generations of directed breeding without significant downsides on other characteristics.
There is a prevalent sense among neurologists that human intelligence has already undergone intense evolutionary selection and that it is subject to certain physical limits. These points are relevant to neuro-eugenic prospects. Hsu in the comments responds to this: "the results imply lots of extant variation to work with. Just imagine flipping all the (-)'s to (+) in a particular person. You get a lot more than +5 SDs." Hsu in the comments: "One important aspect of the toy model I discuss in the talk is that if it is correct, then any couple has the potential of producing a nearly max IQ child, because there will be little overlap between the locations of their (-) alleles." Aha! The path around reproductively negligent female geniuses.
A finely compacted interview of Hsu on his genetics work:
http://intelligence.org/2013/08/31/stephen-hsu-on-cognitive-genomics/
Note that China is financing a major attempt to take the lead in practical human eugenics.
His recent intelligence and heritability presentation (less compacted):
https://www.youtube.com/watch?v=FgCSkGeBUNg&t=5m2s
In sum, this strikes me most forcefully--I had been unaware of the nearness of eugenic capacities--also unaware of their probable potential in the neurological realm. To paraphrase Boswell, my thoughts upon this awful change are in general full of wild apprehensions. This presages a Turn in human affairs, like to surpass all that came before. The implications are all-encompassing.

The Sage Presages: Triple Threat
https://westhunt.wordpress.com/2013/05/09/sustainability/
1. Sub-replacement birth-rate in high-IQ nations
2. Dysgenic fertility pattern in high-IQ nations
3. Historically unprecedented continuous accumulation of mutational load throughout the population in high-IQ nations
=Civilizational collapse if left uncorrected
Cochran's corrective to apocalypticism:
"Again, I don’t believe a word of it [referring to a commenter's claim that average English IQ levels have dropped 15 points (1 std dev) in the last 120 years]. As for the declining rate of innovation, you have to have a really wide-ranging understanding of modern science and technology to have any feeling for what the underlying causes are. I come closer than most, and I probably don’t know enough. You don’t know enough. Let me tell you one thing: if genetic potential IQ for IQ had dropped 1 std, we’d see the end of progress in higher mathematics, and that has not happened at all.
Moreover, the selective trends disfavoring IQ all involve higher education among women and apparently nothing else – a trend which didn’t really get started until much more recently.
Not long enough, nor is dysgenic selection strong enough."

How to Proselytize
HBD means human biological diversity, that is, different races are...uh...different, including genetically.
Basically, to achieve persuasion, he's saying Don't Be An Autist: people respond to emotional manipulation, not logical manipulation. He is right. Political Correctness is a religion. Religions are built on faith. And faith founds itself on emotion. Transform their emotional relation to the topic and they become converts. Expose them to logical fallacies and they retreat into emotional denial. The fact that logic and science happen to be on our side ought not to be a disadvantage--though, in the wonderful world of propaganda it's often irrelevant.

A Sense of Those Who Matter
http://www.vdare.com/articles/graduate-school-admissions-race-and-the-white-status-game
This is particularly damning:
"Data gathered by Richard Sanders of the UCLA Law School shows that 53% of the black students who enter law school fail to qualify to become lawyers, versus 24% of white students. About 40 percent of black law school graduates (many of whom will have taken out crushing loans to pay three years of tuition) never pass the bar exam, compared to 15 percent of whites. Some will also waste additional years working dead-end day jobs while paying to take bar exam review courses at night, before finally giving up in despair."
Anywhere intellectual standards are imposed, major racial differences appear. Ideally, the analysis would also include Jews, who are not a comfortable fit within the white category. Their numbers are doubtless even better than those of the Asians. My first thought in seeing numbers like these is to wonder whether a sufficient number of men in the top IQ percentile are pursuing the ideal of progress, rather than just the idol of Mammon.

Diverse Intelligences
http://www.gnxp.com/blog/2006/02/world-of-difference-richard-lynn-maps.php#2.01
The link is to a lengthy review of a book called Race Differences in Intelligence: An Evolutionary Analysis. I have not read the book, but the reviewer (Malloy) seems a better scholar than the author (Lynn). The main advantage I might derive from looking through the book would be a clearer estimate of the quality of the studies on which the book is based. Distinguishing valid from invalid studies is necessary for scientific progress in any field.
The most obvious and one of the most important points of superiority Malloy evinces over the author is in his discussion of IQ difference between American whites and blacks. It has run at about 15-17 points consistently among various IQ tests and over the course of decades since first tested during World War I. This is roughly a standard deviation. Its real world effects are seen most clearly in differential academic performance, which are more pronounced even than the IQ difference itself (the anti-intellectualism of black American culture and the greater prevalence of poverty among blacks exacerbating the deficit). Thus, this issue is of consequence to America. But, it has, as well, major ramifications for black Africa. Finding the cause ought therefore to be a priority, since it may be remediable. Lynn apparently claims the black American IQ deficit is entirely due to genetics. As Malloy points out (facts well-known to me), there are several environmental factors that may be more detrimental to blacks than whites. He mentions low rates of breast-feeding among blacks compared to whites--studies have shown that more breast-feeding reliably increases intelligence by a few points. I would also note that blacks experience higher lead exposure, which limits IQ potential. Though there is some interesting evidence for Lynn's pure genetics claim (especially the very limited range of black IQ found in various developed nations--average IQs range from 83 to 87 among American, Canadian, Dutch, and British blacks), nevertheless the counterevidence I just mentioned, when added to our imperfect understanding of the environmental determinants of IQ, ought to extinguish his certainty. As I said in a previous post, the science currently points to a combination of nature and nurture as the explanation.
Even Lynn concedes that black Africans, with IQs averaging 67, suffer severe effects from a harsh environment--he calculates the environment costs them 13 points. For those of us who estimate the genetic potential of blacks as higher than 80, as I do and Malloy appears to, the cost is even more brutal. I would estimate it at 18 points. But, whether it amounts to 13 or 18 points, it's a terrible toll. The link between the development of a modern civilization and the average IQ of the population seems a matter of mere common sense. Play out the African bell curve and you find that only 2% of Africans have IQs over 97. In the modern world there are an awful lot of vital things people with sub-97 IQs cannot do--engineering, management of businesses and governments and militaries, programming, entrepreneurship, much of banking and finance, much of medicine, etc. Lynn wrote a useful book on this issue called IQ and the Wealth of Nations. I am disgusted by the ignorance and hypocrisy of those who dismiss the international importance of IQ. Almost every problem poor nations face could be solved by development--but this requires intelligence--sine qua non. The "Wealth of Nations" book has, however, had some influence, as Malloy reminds us: "the 'Copenhagen Consensus', ranked improving micronutrient levels as the second most important action to help the developing world. The impact of nutrition on intelligence was a prominent part of their argument, with 54 references to the word 'cognitive' and 10 references to 'IQ' (Jones 2005)."
As to the evolutionary theory Lynn presents for racial IQ differences, his idea is that people who evolved in the last two ice ages at a higher latitude evolved higher intelligence as a necessary adaptation to a harsher environment. The evolutionary logic is clear, but more evidence is needed. I was surprised by a powerful correlation that Malloy notes: "skin pigmentation (mostly a record of evolutionary latitude according to recent evidence) has a very strong correlation with intelligence, .92." This is shocking. On the other hand, one might wonder whether the poverty and malnutrition prevalent among the darker races in their tropical climes constitutes a cause or a result of low IQ. I suspect both, that is, a low IQ causes a poor environment which contributes to low IQ--a vicious circle, in effect.
I enjoy making educated guesses. They involve the mind in such challenges as absorbing new information, ordering and organizing it, identifying biases in the information and in one's mind, deducing the completeness of the information. I think Lynn's theory is correct, that there is a cline of intelligence influenced by the latitude at which evolution occurred--but, I also think there are other genetic factors in racial differences and highly significant environmental differences. The main point of this whole investigation is to find out what are the environmental factors in IQ--finding the genetic factors is useful only to that end, since we are not yet in a position to modify genes. The maximum of racial IQ differences (eg, NE Asian vs black African) seems to be 20-25 points under equalized developmental conditions. It may be lower than that. I posit that a twenty point difference between societies constitutes a difference in kind, not of degree. For example, comparing a healthy black African society with an average IQ of 80 and a European society with an average IQ of 100 (presuming racial homogeneity in each), one discovers that in the IQ range of 130+ which is a precondition for technical innovation the Africans would be outnumbered by a ratio of at least 70 to 1. They would be outgunned in many other fields as well: commercial competition, scientific research, espionage--but, almost every aspect of modern society is dependent upon the intelligence of its members. See: http://www.udel.edu/educ/gottfredson/reprints/1997whygmatters.pdf
Also, there may be numerically small groups who make exceptions to this limit. For example, Ashkenazi Jews have IQs estimated anywhere from 103 to 115 under developed conditions. African Bushmen and Australian Aborigines are about 54 and 62 under undeveloped conditions. Under equal conditions these relatively small groups might still be 30-40 points apart. Much more research remains to be done, probably led by the Chinese given Western "moral" reservations (I would call them immoral reservations). The research ought to focus on remediation among the poor, as the Copenhagen conventions implicity recommended, since this is the most feasible near term goal. But, with a Chinese lead it looks to go a different way, toward the fashioning of genetically engineered or pharmaceutically powered super intelligence--which, though it might not be cost-effective from a global perspective, is much after my own taste.
