Standardized Test Scores vs. # of Brain Cells & Head Size

 SAT math scores increase 6 points for each 1% increase in brain or head size. GRE test scores, crime rates, annual incomes, and brain size correlate closely with each other. Why the US INS viewed jews as "simple minded ... morons" in 1924. The effect of race on earning capacity. The volume of gray matter and IQ correlate closely. Annual salaries increase by \$660 for each 1% increase in brain or head size.

"women have about a 5 point IQ deficit and smaller brains than men... the IQ gap between blacks and asians is no less than 30 points!

if u would like to see the hard data on this u can look it up as to Rushton work and i have several data sets along this line as well... if u could hold the gray matter difference IN YOUR HAND!"

Again I should point out that the correlation between brain size and IQ is not nearly as close as the correlation between brain size and GRE scores, as evidenced by the following r-squared for brain size correlated with:

IQ = 0.75
GRE Analytical = 0.57
GRE Verbal = 0.58
IAEP Math = 0.58
NAEP Math = 0.70
TIMSS Science = 0.81
ACT Math = 0.84
GRE Quantitative = 0.88
TIMSS Math = 0.94
Earnings = 0.95

The poor correlation between brain size and both IAEP and NAEP scores I attribute to gender-mandering by the US Department of "Education", and the good correlation with TIMSS math and science I attribute to a foreign agency sans this race mixing and gender-mandering agenda. And the good correlation with GRE quantitative scores I attribute to their remaining fairly neutral and objective in spite of the effort by feminazis to change it all or even shut them down.

What does this mean?  That the gender gap in the most important attributes to a society or an economy is at least one standard deviation, and the gender gap in wages, even for teachers, is TWO standard deviations.

Within each race, this would be the equivalent of a 15 to 30 point gap in IQ, not 5.﻿

Correlation between brain size and intelligence increases from GRE Analytical at r-squared = 0.57, to IAEP Math and GRE Verbal scores at r-squared = 0.58, to TIMSS Math a 0.71, to TIMSS Science at 0.81, to GRE Quantitative at 0.88, to annual earnings at 0.95.

The simple explanation would be that as a test focuses more on intellectual skills and less on memorization questions, it more closely mimicks a real test of intelligence, and thus correlates more closely with brain capacity.  Nobody denies that the bigger a muscle is, the stronger it is, or that the bigger a microcomputer is the more it can process, so why would we deny that the bigger a brain is, the more capacity it has for intellectual challenges and computations?

following article fails to report the standard deviation of the number of brain cells for each sex, but if it is equivalent with things like Olympics scores, then the standard deviation for men is 0.43% and for women is 0.75%.   This would mean that two thirds of men have between 22.7 to 22.9 billion brain cells and two thirds of women have between 19.2 to 19.4 billion brain cells.

agree that the analyses and calculations necessary to take the SAT take place in the brain is correct.  To agree that the precise process by which this occurs is not well understood is correct.  To know that these extra 3 1/2 billion brain cells constitute 18.1% of the male brain's mass is correct.

But there is no analytical process whatsoever by which it can be proven that there is absolutely no causation for this precise correlation.  There is no way to know that not even one single one of these extra 1.8 quadrillion brain cells contributed to even a 0.001% increase in the SAT score of at least one male.  How could exactly 3 1/2 billion brain cells--18.1% of the male brain--refuse to participate in the SAT test (out of a sense of fairness to females?), while the remaining 19.5 billion brain cells continue to "discriminate" against females, by outperforming female brains by 18.5%?

If 18.1% of the brains of these 522,000 male test takers were removed, would those males still collectively score 27.6 million more SAT points than females?  What is it about this 81.9% of the male brain that it performs 18.5% better than a female brain of equivalent size?  Is it made of a superior material?

Who would bet their life that not even 2 out of these 1.8 quadrillion brain cells might sneak across the feminists' invisible line and cause a 0.001% increase in an unsuspecting male's SAT Math score?  Who is willing to bet trillions of dollars of taxpayers' money that this is the case?

The statement is an utterly absurd and cynical hypothesis from a bunch of PMS charged feminists whose frustration about their inability to grasp abstract concepts shines through in the international press.  For each 1% increase in the percent of feminists who "think": "I am good at math", their TIMSS scores decrease two points.

Such absurd assumptions and social engineering by feminists who haven't got a clue what engineering and science are increased the cost of education in the US from 4.8% of GDP in 1959 to 7.6% of GDP in 1993 (Table 31).  They increased education costs by \$215 billion just last year and more than \$7.3 trillion over the last 40 years.  Yet SAT scores plunged 98 points, 98% of those taking the GRE test who score in the fiftieth percentile are males and only 2% females, the US is dead last in TIMSS geometry & last in IAEP math, & the "gender gap" in test scores didn't budge a point!

Educators have turned a stupid idea into an utterly remarkable failure!  US education ranks as one of the best of the Twenty Nine Phenomenal Federal Flops.

Differences Between Boys and Girls Are Found in
Nature and the Brain not in Socialization

Renowned Experts Tell National Press Club Audience

WASHINGTON, DC (September 18, 2000) – Leading experts on research into brain differences between boys and girls, told a National Press Club luncheon crowd on Friday the 15th that biology—not social construction—explains sex differences. This has significant implications for both education and the workplace.

Speaking at an event sponsored by the Independent Women’s Forum (IWF), “The XY Files: The Truth is Out There About the Differences Between Boys and Girls,” the panel of experts noted that both society and boys are being harmed by fashionable, but misguided, feminist notions. Said Lionel Tiger, Charles Darwin Professor of Anthropology at Rutgers University and author of The Decline of Males: “The androgynous commitment to the notion that the sexes are all the same is essentially causing chronic private trauma in countless lives because there is no articulation between the social structure and the real needs of and feelings of people.”

Challenging the gender experts who see male/female differences as created by socialization, Doreen Kimura, Professor of Psychology at Simon Fraser University and author of Sex and Cognition, presented science. “Some of the sex differences in intellectual or cognitive patterns are biologically influenced early in life and a major factor is the different hormonal milieu experienced by males and females before or shortly after birth,” she reported.

Patricia Hausman, a behavioral scientist specializing in the nature and origins of human sex differences, agreed. “Many argue that changes in the social environment could eliminate sex differences in interests,” she said. “To me, this perspective mistakenly assumes that the ‘social environment’ is something that Big People force on Little People. I think it is often the other way around. The Little People send signals to the Big People about what they do and do not like, and the Big People respond accordingly. Parents who buy more dolls for a daughter are probably not forcing them on her. More likely, they are reacting to observations that she did not find a toy truck particularly captivating, but lavished attention on her first doll.”

The refusal of the education system to accept what science says about boys and girls is having devastating effects on children, especially boys, the panelists warned. “The problem with [popular feminist] dogma is that it gives enormous latitude to educators who want to tamper with children’s gender identities,” said Christina Hoff Sommers, W.H. Brady Fellow at the American Enterprise Institute and author of The War Against Boys. “This dogma has inspired activist-educators to take on the challenge of resocializing little boys to be more like little girls.”

Tiger concluded by echoing Sommers. “We’re now trying to solve the problem of young males by saying that they’re essentially young females,” he said. “What is happening though is that boys do less well in school and they don’t go on to college as often. This will have implications for these young men to be seen as acceptable or plausible candidates for marriage.”

Which leads to a warning for all of those so-called gender experts: Don’t mess with Mother Nature.

 Have 3 1/2 Billion or 18.1% More Brain Cells than women! Men have more brain cells than women, study finds Copyright (C) 1997 Nando.net Copyright (C) 1997 Agence France-Presse COPENHAGEN (July 28, 1997 10:04 a.m. EDT) - Men have 16 percent more brain cells than women, but the extra gray matter does not make them any smarter, Danish researchers report. Neurologists Bente Pakkenberg of Kommunehospitalet and Hans Joergen Gundersen of Aarhus University analyzed the brains of 94 Danes who died between the ages of 20 and 90. Their final tally, reported in the Journal of Comparative Neurology, was that men have an average of 22.8 billion brain cells, compared to 19.3 billion for women. "We were surprised by the difference," Pakkenberg told AFP. "We did not think it was so big, even though men's brains weigh more." That disparity is 150 grams, she said. The research team used a technique that analyzed the brain layer by layer and gave a more accurate cell count, she said. But Pakkenberg insisted the difference in cell number does not show up in tests measuring male and female intelligence. "In these tests it is possible that men are better at some things than women, but in general they are not more intelligent," she said. Copyright (C) 1997 Nando.net                               The major outlier is black men, which can be explained by any number of factors, and removing them increases r-squared to 0.67 for GRE Verbal, 0.69 for GRE Analytical, 0.71 for IAEP math, 0.84 for TIMSS Math, 0.91 for TIMSS Science, 0.96 for GRE Quantitative, and 0.98 for annual earnings.  Following are the graphs with this one outlier removed: 522,000 men and 522,000 women take the SAT each year. Men with 3 1/2 billion more brain cells each, who score an average of 53 points higher.  It is scientifically impossible to prove that this is because of "discrimination" and not because of their collective 1.8 quadrillion more brain cells.  Men collectively score 27.6 million more SAT points than females, which is 65.2 million brain cells for each extra SAT points   There is utterly no way for anyone to KNOW or to prove that these two variables are independent of each other.
