I Feel Like A F**king Dupe
One of my e-mail correspondents sent me an e-mail bemoaning the turn to hard social conservatism of the Republican Party. He was also regretting that he supported so many Republicans who have now turned on the Tea Party (he also worries that the Tea Party may be turning into a socon movement rather than sticking strictly to fiscal conservatism) . So I decided to do what I could to buck him up.
Here is my reply. With a few added notes in brackets [ ].And amended for the sake of the privacy of my correspondent:
========================
I feel like a fucking dupe.
Aren't we all? It is like any revolution. The old order gets shaken up and no one knows what will replace it. A new birth of liberty or just a different kind of totalitarianism.
Maybe it is time to form some groups of our own - may I suggest: LiberTea? Kinda catchy don't you think?
BTW O'Donnell was a member of the Delaware Republican establishment until she had a chance of winning. [note: O'Donnell may be a socon with libertarian political beliefs. Kinda like Palin.]
For the most part I run on hope (well I do have my bad weeks) and I do believe I can change some minds at the margins. So I keep hammering away at the same old themes. You never know who may have missed my last polemic. In advertising most advertisers give up on a winning idea when the advertiser gets bored of it. Well before the audience gets tired. I try to avoid that mistake.
We are at war with the statists of the right and left. So what do we have? I'd say at this point maybe 10% to 20%. Not enough to move things yet. But more than enough to work with.
Just remember Captain Jones. His ship is sinking. When he fires his guns more of his crew die than he kills of his enemies. So what is his reply when the opposing Captain asks, "Have you struck?" And of course his reply has gone down in history (maybe not exact), "I have not yet begun to fight". He maneuvers his ship into close quarters, grappling the opposing ship, and the Marines in the foretops clear the decks of the opposing Captain's ship and they board. After a bloody hand to hand fight he takes the Serapis and watches his ship sink. Victorious.
In battles things often look darkest when you are close to victory. Both sides are exhausted. The side that can at that point surge wins.
We are (IMO) far from that point. But we are wearing them down.
It has taken us 40 years to come even close to ending the drug war. But victory is in sight. Once that blows up in the faces of the statists they will have a lot of answering to do. "Don't give up the ship".

Statistical Sun
While noodling around the 'net I came across a statistical study of the history of sunspots and the Earth's climate. (if the English is less than perfect it is because the person writing is a native of Finland)
When the planetary effects have been searched as a cause for sunspots, a gravitational effect is mostly assumed. My theory is purely statistical so it does not necessitate a theory about the physical background. But still one can make some speculations. Evidence strongly suggests that the sunspots have a clear electromagnetic nature. The solar system baths in the electromagnetic field of the Sun. Nasa announced in 2008 that there are some kind of electromagnetic "ropes" between the Sun and possible all the planets that have an electromagnetic field of their own (such as Earth and Jupiter for example).The author takes a look at what this all might mean for the weather on Earth.
I make a suggestion: The electromagnetic fields of Sun and Jupiter are partly intertwined, sometimes more, sometimes less during the nearly 12-year orbital revolution of Jupiter. Changes in eccentricity may then cause long-period changes in Sun's activity. And one thing we don't know: if the theory of everything combines gravity and electromagnetic forces the warping of space around Sun would really cause something extraordinary, like changes in the Sun's activity. One interesting thing is, that although the main effect of Jupiter seems to come via the perihelia of Jupiter, also the points where Jupiter crosses the plane of equator of the Sun, seem to have some effect.
According to my theory about Jovian effect on sunspots, based on facts measured since 1700 and estimated since 1500 (Schove)Now how about the NASA study of electromagnetic ropes? (this is from late 2007)
- The Jupiter perihelion and sunspot minimum never coincide and the nearing perihelion in 2011 will slow the rise of the height of sunspot cycle, as now is happening to the cycle 24.
- The Gleissberg cycle almost reached its lower limit, which is 72 years in 2005.
--- In fact this low it has not been ever after the Maunder minimum.
--- So it must go up, the short cycles of the 20th century has created a debt that must be paid.
--- This means lower cycles and if the past is a good predictor, colder times on Earth.
"The satellites have found evidence of magnetic ropes connecting Earth's upper atmosphere directly to the sun," said David Sibeck, project scientist for the mission at NASA's Goddard Space Flight Center, Greenbelt, Md. "We believe that solar wind particles flow in along these ropes, providing energy for geomagnetic storms and auroras."I wonder if the IPCC has included this in their models? Probably not since it is not well understood. How many other things that may or may not affect climate are not well understood? And that is just the known unknowns. Could there be some unknown unknown that affects climate that we are missing? Well the answer of course is: we don't know.
A magnetic rope is a twisted bundle of magnetic fields organized much like the twisted hemp of a mariner's rope. Spacecraft have detected hints of these ropes before, but a single spacecraft was insufficient to map their 3D structure. THEMIS' five identical micro-satellites were able to perform the feat.
"THEMIS encountered its first magnetic rope on May 20," said Sibeck. "It was very large, about as wide as Earth, and located approximately 40,000 miles (70,000 km) above Earth's surface in a region called the magnetopause." The magnetopause is where the solar wind and Earth's magnetic field meet and push against one another like sumo wrestlers locked in combat. There, the rope formed and unraveled in just a few minutes, providing a brief but significant conduit for solar wind energy.
And on the basis of all this shaky science we are going to spend trillions on Waxman-Malarkey [pdf]? The Senate has not yet passed the bill. So we still have a chance. Contact your Senator:

The Real Margin Of Error
I was over visiting The Volokh Conspiracy's discussion of the polls. And I Said something like:
America is not a predominately socialist/communist country.Commenter LM came back at me and said that saying that America is not a socialist/communist country was a veiled smear. Well that set me off for another round. And this is what I said (revised and extended):
As to why the polls are wrong: the pollsters are cooking the books. Operation Chaos screwed voter ID numbers. Republicans don't like being polled. PUMAs are being seriously under counted.
LM,
Interesting - saying America is not a "share the wealth" country is a smear. OKy doake.
Second,
How about all the predictions of Obama wins in the primaries that saw 10, 20, 30, and in some cases 40 point swings (polls vs reality) in Clinton vs Obama.
Big Obama Win Predicted.
Of course the pollsters have gotten all that fixed and now their predictions of a big Obama win are right on the mark. Why take Pennsylvania for instance. Despite a big Obama loss in the primaries, Obama has converted all those Clinton voters and Republicans and is now poised for a big win there.
Sure it is possible. What are the odds?
The polls this year are GARBAGE. Let me spell it out for you: G. A. R. B. A. G. E.
Their connection to reality is tenuous at best. They called a bunch of people. They got answers to questions. They then adjusted the numbers to match their proposed model of reality. Which is all good if their model is correct.
But suppose most of the D surge in registrations was Operation Chaos people? Those should be shifted from D to R. Or perhaps their view of defecting Democrats is about 20% of Hillary voters and it is actually 40%. Obviously if you get "too many" of them in a sample you have to scale it back 60% or 70% of that demographic.
And how about the 80% that won't answer the pollsters. Does their demographics match the 20% that do answer?
With those kind of response rates you have a self selecting sample. A no no in statistics. Not random. All opinions don't have an equal chance of being sampled. So what is the weighting for that? Well you sample the people that don't want to be sampled and adjust your samples to match the total pool. But how do you randomly sample people that don't want to be sampled to find out what the bias is?
But it is worse. All these numbers are shifting all the time and from place to place. And sample demographics vary from day to day. How many church goers are you going to sample from 9AM to 1 PM on Sunday? How many employed people will you get from 8 AM to 5 PM on workdays? If you sample in the evenings how many 2nd shift workers do you get? How many long haul truckers do you get on any day?
In Hillary vs Obama the polls at least about 1/2 the time weren't even close. No where near the "margin of error". All we know is the statistical margin of error given the sample size. We know nothing about the real margin of error.

The Numbers Game
More than one person has asked me why the polls are so out of whack with what they see as their reality. So what is that reality? I think a few anecdotes are in order. First from commenter Daddy at Just One Minute.
Arriving in Indy about midnight I asked the 2 female bus drivers how did the ballgame come out and they both replied they weren't listening to any ballgame they had been listening to the debate. Both were enthusiastic and pumped, and extremely complementary of Sarah's performance, especially since they had been led to believe she was going to do so poorly. The female Cab driver was very jazzed as well and said exactly the same thing. Ditto for the check-in lady in the hotel. Later at The Redeye Cafe in downtown Indy for a 2 AM Guiness and Spanish Omelette (Yumm!), the bartender girls were also oblivious of ESPN and SportsCenter on the overhead TV's behind, and both were still complementing Sarah on her performance. All these girls were Colts fans, and they were acting exactly like they do when their Colts win a playoff game. I have no idea what any of their politics were, but it seemed that Sarah's performance was somehow something they took personally, and they were proud of how she did. I never did get any opinions from any guys what they thought about the debate since apparantly women do all the work after midnight in Indianapolis, but my unscientific survey of the working girls of middle America is that Sarah made a very big and a very positive impression. Whether or not it'll turn into votes for her, who knows.Here is one from commenter Sharen at No Quarter.
Comment by Sharen 2008-10-04 23:19:36And finally one from Porchlight at Just One Minute.
Yesterday I was going to The Grove in Los Angeles, I don’t know where your at but if your not familiar with the area, its basically West Hollywood, and I was SHOCKED, SHOCKED by how many McCain/Palin signs I saw, I told my Mom to stop the car and I was like OMG LOOK AT ALL THESE SIGNS, I saw 1 Obama sign and the rest was a sea of McCain/Palin signs, around here in liberal Los Angeles county seeing McCain signs is very unusual, it must have gone on for two blocks, in total, 3 Obama signs, and the rest were McCain/Palin, TWO BLOCKS, I was like damn, am I in Orange County LOL. I swear if California goes Red I will eat my shoe, I don’t see it happening but ya never know
Daddy,So why isn't all this showing up in the polls? There are reasons. Some good. Some not so good. And some there is no way to account for.
Thanks for the Indy update. I am trying to figure it out. Wildly enthusiastic audiences for Palin, RNC fundraising for September 1/3 higher than their previous record, VP debate viewership 1/3 higher than previous VP debate, etc. Why isn't this showing in the polls?
So how about the good? Registrations for Democrats is way up. Rush Limbaugh with his Operation Chaos plan to derail Hillary got a bunch of Republicans to register as Democrats to defeat Hillary. So the pollsters believe the Republican party has lost support.
How about the bad? The newspapers and most TV networks are so obviously in the tank for Obama this year that they aren't even making a pretense of a pretense of objectivity. So they get the polls with numbers they are happy to report and that helps their candidate by depressing the other side.
And how about the no way to account problems with polls? People lie to pollsters. Unsourced anecdote: a nice sounding black lady calls and asks who you are voting for? Are some people going to be nice and say Obama when in reality it is going to be McCain? It happens.
Now how about some analysis by people smarter even than me. Let me start with A.J. Strata's view on cooking the polls.
Voter models are the essence of political polls. You take a sample of a few hundred or a few thousand people and predict how that sample can reflect 10s-100s of millions of people. If you are off by even a small fraction in your assumptions the bottom line could be off by 5, 10 or 20% (despite an MoE claim of a few points).Go to A.J.'s for the links. And A.J. has more so if you want details give him a read.
We have a perfect example of this in two Colorado Polls out recently. The first poll was commented on by our Reader MerlinOS2:PPP just released a poll in Colorado which puts Obama up +7Details on the poll in question can be found here. Just this week American Research Group (ARG) also released a poll for Colorado (which is not used in the RCP poll of polls strangely). Its voter model was Dem 32%, Rep 35% and Ind 33%, very close to the ACTUAL voter registration levels noted by MerlinOS2. The result: McCain 48%, Obama 45% - a McCain lead of +3%. (Note: this polls also shows McCain tied with women)
Now what the issue is here is that the party split was
Dem 40
Rep 36
Ind 24
However August voter registration number per the spreadsheet available from the Secretary of State show the registration breakdown is
Dem 30.6
Rep 34.8
Ind 34.5
These polls were taken at basically the same time in the same state. But we can see how the voter model can really change the bottom line (a 10% difference).
Newsbusters looks at the fabrication side of polling. You know. They just make shit up. Again it is all about party weightings.
In the kitchens of the Associated Press, it's almost as if the wire service asked its chief cook -- er, pollster -- GfK Roper Public Affairs and Media, to do the following:Read the article if you want to check out the links. Me I want to look at some numbers and we do in fact have a few.* Whip up a tasty, representative poll after the Republican Convention.Of course we don't know if the differences between AP-CfK's Sept. 5-10 and Sept. 27-30 results were created deliberately, but the results sure look suspicious (both polls are available at PDF links found at AP-GfK's home page).
* Three weeks later, make the same dish, but this time adjust the mix of ingredients by radically oversampling Democrats and undersampling Republicans, thereby creating a false illusion of momentum in the campaign of Barack Obama, and of decline in John McCain's.
* Hope people don't notice the changes in the recipe.
"Somehow," the sample make-up changed from 33-31 Democrat to 40-29 Democrat from the earlier to the latter poll -- a shift of nine points.Well Newsbusters has charts full of numbers and more text so for the numbers obsessed (hey there may be a key to winning the lottery in there) have a look. There is always more to learn.
"Somehow," the Strong-Dem vs. Strong-GOP difference went from nothing to eight points.
"Somehow," the Strong-GOP vs. Moderate-GOP mix went from +3 to -3, a swing of six points.
I'd like to finish up with analyst DJ Drummond of Stolen Thunder whose motto is: A man must be accountable, else everything he does counts for nothing. Yep. Any way DJ looks at the Secret Poll
I have been working through the poll numbers for quite a while now, sorting out valid patterns from the fakes. I held off posting the true state of things for a long time, for a number of reasons, but I notice that some on the Right have begun to lose hope and make sounds of giving up. So I will tell you plainly, thatNow I have cribbed everything DJ posted. Which is kind of like stealing. In fact it is stealing. In my defense it wasn't a long post and DJ answers some interesting questions in the comments. So do the right thing and give him a click. Plus his advice is critical: keep the faith. Do not give up. Make sure you and all your friends show up on election day.
We Are Winning
and can only fall in this election if you give up. It's been a long road and the enemy has been his usual foul self, with lies and smears and everything we have learned to expect from people who put power above any moral or honorable precepts. It's close, but here's where we have been, and where we are:
August 31: McCain 41.77%, Obama 41.06%
September 7: McCain 42.45%, Obama 42.04%
September 14: McCain 45.71%, Obama 39.62%
September 21: McCain 44.48%, Obama 42.06%
September 28: McCain 42.73%, Obama 41.62%
And based on the demographic responses, once the undecideds shake out if we work as hard as we can and continue to keep faith, the final popular vote will be
McCain 51.59%
Obama 48.41%
Keys to remember:
This is not a football game or a baseball game, it's politics. Support is built up gradually and won bits at a time. Also, some of the best gains are not obvious at first, because some significant actions take time to develop. McCain and Obama both fell back a bit the last week of September, McCain because Republican support fell off a bit, Obama lost independents' support. This is a salient factor in where the candidates' opportunities and weaknesses lay.
I'm going to double down on the above comments. Here is what I say about all this. Again: Let us not give Obama the election by staying home depressed on election day. If he is going to win make him earn it. Get out and vote and make sure everyone you know gets out and votes. Make him know he was in a fight.
In other words fight the trolls on the blogs. And come election day get out the vote like your life and your country depended on it. Because it does. Even in a state like Illinois where I reside, every vote counts because it adds to the popular vote totals even if your state is going for Obama in the electoral college.
And if you want to do something about vote fraud read this, because polls aren't the only way the numbers are being cooked this year.

Inequality
According to the American founders all men are created equal.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed,...Does that mean all men have equal talents? Of course not. Some are fast runners and some are slow runners. Some are very smart some are not so smart. The equality the founders professed was equality before the law. And there by hangs a tale.
What I'm going to look at here is inequality. Let us start with sports.It seems some people run faster than others. I guess we have races to find out who is fastest of the fast.
Running offers the best prima facie case for the potential impact of body type differences. Athletes of West African descent dominate sports requiring speed and jumping, such as basketball and football. They hold the fastest two hundred 100-meter times, all under 10 seconds, and 494 of the top 500 times. In last weekend's NFL draft, of the 69 players who ran the 40-yard dash in 4.5 seconds or less, only one is white.How about marathons? That is a little different story.
Humans are different, the consequence of thousands of years of evolution in varying terrains. This is not an issue of black and white. East African blacks, from Kenya and Ethiopia, for example, have traveled a different evolutionary path and are genetically distinct in many aspects of their body type and physiology from West Africans. The best East African time in the 100 meters, 10.28 seconds, ranks near 5,000 on the all time list.White folks sure got short changed when it comes to being runners. There must be some kind of athletics white people are good at. In fact there is.
While relatively poor sprinters, East Africans win more than 50 percent of top endurance races. Almost all trace their ancestry to the 6,000-8,000 foot highlands that snake along the western edge of the Great Rift Valley. This region of roughly 1.5 million wins 40 percent of international distance events. The Nandi district in Kenya, 500,000 people – one-twelve-thousandth of Earth's population – sweeps an unfathomable 20 percent, marking it as the greatest concentration of raw athletic talent in the history of sports. They win in large measure because elite runners have a near perfect biomechanical package for endurance: lean, ectomorphic physiques and huge natural lung capacity.
"Kenyans are born with a high number of slow twitch fibers," states Bengt Saltin, director of the Institute of Sports Science in Copenhagen. "They have 70 to 75 percent of their muscle fibers being slow. Very many in sports physiology would like to believe that it is training, the environment, what you eat that plays the most important role. But based on the data it is 'in your genes' whether or not you are talented or whether you will become talented."
Genetically linked, highly heritable characteristics such as skeletal structure, the distribution of muscle fiber types, reflex capabilities, metabolic efficiency, lung capacity and the ability to use energy more efficiently are not evenly distributed among populations and cannot be explained. For example, whites of Eurasian ancestry, who have, on average, more natural upper-body strength, predictably dominate weightlifting, field events such as the shot-put and hammer (whites hold 47 of the top 50 throws), and the offensive line in football. Where flexibility is key, East Asians shine, such as in diving and some skating and gymnastic events (hence the term "Chinese splits").What does he mean by cannot be explained? I think he means that there is no explanation for the clustering of traits in certain groups other than isolated populations in different environments. Natural selection. Darwin in action. In the 100,000 years since our ancestors left Africa we have differentiated according to environment. That is pretty rapid evolution.
So what is all this race stuff any way? It is not like the different races can't interbreed. Isn't race just a social construct? Well no.
Several analyses have confirmed the genetic reality of group identities going under the label of race or ethnicity. In the most recent, published this year, all but five of the 3,636 subjects fell into the cluster of genetic markers corresponding to their self-identified ethnic group. When a statistical procedure, blind to physical characteristics and working exclusively with genetic information, classifies 99.9 percent of the individuals in a large sample in the same way they classify themselves, it is hard to argue that race is imaginary.Now here comes the hard part. I think that it is now evident and different races have different athletic talents and even within races there are still more subdivisions. What about cognitive ability? Something the scientists call 'g', but we will call it by its better known but somewhat inaccurate term intelligence quotient or IQ. The term 'g' refers to raw computing power. IQ (not 'g') is divided into two main parts. Verbal and spatial intelligence.
Let us look into a real world example, Ashkenazi Jews, to see how this works.
Ashkenazi levels of real world accomplishment are impressive and thus support the IQ studies. Jewish Americans make up no more than three percent of the U.S. adult population. But in the 1995 book Jews and the New American Scene, the prominent social scientist Seymour Martin Lipset, a Senior Scholar of the Wilstein Institute for Jewish Policy Studies, and Earl Raab, Director of the Perlmutter Institute for Jewish Advocacy at Brandeis University, pointed outSo that is one example of variation on the high end. The results are obvious. The differentiation of the Ashkenazi Jews happened in a span of 1,000 years or less. That is very rapid evolution."During the last three decades, Jews have made up 50% of the top two hundred intellectuals, 40 percent of American Nobel Prize Winners in science and economics, 20 percent of professors at the leading universities, 21 percent of high level civil servants, 40 percent of partners in the leading law firms in New York and Washington, 26% of the reporters, editors, and executives of the major print and broadcast media, 59 percent of the directors, writers, and producers of the fifty top-grossing motion pictures from 1965 to 1982, and 58 percent of directors, writers, and producers in two or more primetime television series." [pp 26-27]Interestingly, the Ashkenazi cognitive advantage seems to be mostly in verbal and numeric, rather than visual, skills. For example, in Hollywood, fewer top cinematographers are Jewish compared to screenwriters or agents.
So are Ashkenazis a race? Maybe. What they are for sure is an identifiable sub group based on DNA (their DNA is most like Arabic DNA, not too surprisingly) and genetic diseases that cluster in the Ashkenazis like Tay Sachs.
What about variation on the low end? Here comes the really hard part.
When the late Richard Herrnstein and I published The Bell Curve eleven years ago, the furor over its discussion of ethnic differences in IQ was so intense that most people who have not read the book still think it was about race. Since then, I have deliberately not published anything about group differences in IQ, mostly to give the real topic of The Bell Curve--the role of intelligence in reshaping America's class structure--a chance to surface.The American Psychological Association, not a hot bed of racism, checked out The Bell Curve and this is what they found.
The Lawrence Summers affair last January made me rethink my silence. The president of Harvard University offered a few mild, speculative, off-the-record remarks about innate differences between men and women in their aptitude for high-level science and mathematics, and was treated by Harvard's faculty as if he were a crank. The typical news story portrayed the idea of innate sex differences as a renegade position that reputable scholars rejected.
It was depressingly familiar. In the autumn of 1994, I had watched with dismay as The Bell Curve's scientifically unremarkable statements about black IQ were successfully labeled as racist pseudoscience. At the opening of 2005, I watched as some scientifically unremarkable statements about male-female differences were successfully labeled as sexist pseudoscience.
The Orwellian disinformation about innate group differences is not wholly the media's fault. Many academics who are familiar with the state of knowledge are afraid to go on the record. Talking publicly can dry up research funding for senior professors and can cost assistant professors their jobs. But while the public's misconception is understandable, it is also getting in the way of clear thinking about American social policy.
Good social policy can be based on premises that have nothing to do with scientific truth. The premise that is supposed to undergird all of our social policy, the founders' assertion of an unalienable right to liberty, is not a falsifiable hypothesis. But specific policies based on premises that conflict with scientific truths about human beings tend not to work. Often they do harm.
One such premise is that the distribution of innate abilities and propensities is the same across different groups. The statistical tests for uncovering job discrimination assume that men are not innately different from women, blacks from whites, older people from younger people, homosexuals from heterosexuals, Latinos from Anglos, in ways that can legitimately affect employment decisions. Title IX of the Educational Amendments of 1972 assumes that women are no different from men in their attraction to sports. Affirmative action in all its forms assumes there are no innate differences between any of the groups it seeks to help and everyone else. The assumption of no innate differences among groups suffuses American social policy. That assumption is wrong.
There is no technical dispute on some of the core issues. In the aftermath of The Bell Curve, the American Psychological Association established a task force on intelligence whose report was published in early 1996. The task force reached the same conclusions as The Bell Curve on the size and meaningfulness of the black-white difference. Historically, it has been about one standard deviation in magnitude among subjects who have reached adolescence; cultural bias in IQ tests does not explain the difference; and the tests are about equally predictive of educational, social, and economic outcomes for blacks and whites. However controversial such assertions may still be in the eyes of the mainstream media, they are not controversial within the scientific community.What does all this mean?
The most important change in the state of knowledge since the mid-1990's lies in our increased understanding of what has happened to the size of the black-white difference over time. Both the task force and The Bell Curve concluded that some narrowing had occurred since the early 1970's. With the advantage of an additional decade of data, we are now able to be more precise:
(1) The black-white difference in scores on educational achievement tests has narrowed significantly.
(2) The black-white convergence in scores on the most highly "g-loaded" tests--the tests that are the best measures of cognitive ability--has been smaller, and may be unchanged, since the first tests were administered 90 years ago.
Let us start with some simple statistical assumptions that are aproximately correct and see if we can figure out what the implications are. First IQ. Ashkenazi Jew IQ is 115. White IQ is 100. American black IQ is 85. These are averages. They tell you NOTHING about individuals. Let us also assume a standard deviation (a measure of variation) is 15 for all groups. I'm going to use this handy bell curve calculator to get my results.
What percentage of white Americans are going to be top college material with an IQ above 125? About 5%. How many Ashkenazi Jews will be found in that range? About 25%. How many American blacks (African blacks are significantly different)? About .4%. Which means if we follow merit alone, there ought to be about 10 times as many whites per capita as blacks capable of work in our top institutions. This is a depressing fact of life, just as the Ashkenazi Jews are a bright spot.
It gets worse at the very high end. For scores above 160, the brightest of the bright, among the Ashkenazi Jews the proportion will be about one in a thousand. For whites the number is zero (actually that really means less than one in 10,000 because the calculator does not do really small fractions) and for blacks the number will be a much smaller percentage than whites. Given that Ashkenazi Jews are at least 100 times as likely to be in that range relative to whites and Ashkenazi Jews represent about .1% of the world's population, the results we see above are not unexpected.
We see all this born out in the top science and math prizes.
So the question as Lenin put it is: "What is to be done?" First off treat people as individuals not statistics. Every one has their own group of talents that should be develped as fully as possible.
Second off we are turning into a society whose rewards are based on cognitive ability. Something the Bell Curve guys discuss at length. What is their answer, besides giving every one a fair shot to develop their talents? They suggest socialism light. The top perfomers should be able to reap top rewards for top performance. Not every one gets first prize in the race. However, because of the work of these top performers, labor doesn't have the value it once did. "John Henry, the Steel Driving Man" was a harbinger of that. It is hard to compete, labor wise, with a motor controlled by a microprocessor. So the top performers are going to have to help those on the bottom, if for no other reason than to keep the peace. Socialism lite.
Milton Friedman and a number of others (including The Bell Curve authors) think that the negative income tax (instituted by Nixon) is the way to go because the bureaucracy required is minimal.
I think we also have to accept that there is a limit to what our public schools can accomplish. Each added increment of resources is going to produce a diminishing return.
There are lots more policy implications in all this. More than I can deal with here. The main point for me is that even in a race blind society not all races will do equally well at all tasks.
A couple of books that might be of interest:
