Race, Obesity, Poverty, and IQ

2100 words

America has a current and ongoing obesity epidemic. Some ethnicities are more likely to be obese or overweight than others due to lower intelligence which means a lack of ability to delay gratification, lack of ability to think into the future, lower funds which translates to eating more refined carbohydrates which means more blood glucose spikes which then leads to obesity as I will show. Insulin has a causal relationship with obesity so those who lack funds to buy healthier food then turn to refined foods high in carbohydrates as they are cheaper and more abundant in low-income neighborhoods.

Adult obesity rate by State (top 5) is: 1) Louisiana (36.2 percent), 2) Alabama (35.6), West Virginia (35.6), and Mississippi (35.6), and 5) Kentucky (34.6) with the 5 least obese States being 51) Colorado (20.2), 49) Hawaii (20.7), 48) Montana (23.6), 47) California (23.2), and 46) Massachusetts (24.3). Notice how the States with higher rates of obesity are in the South and the States with the lower rates are in the North, give or take. The average IQ for these States as follows: Lousiana: 95.3, Alabama: 95.7, West Virginia 98.7, Mississippi 94.2 (lowest IQ State in the country, largest black population at 37 percent), and Kentucky at 99.4. The average IQ for those States is 96.66. The average IQs for the States with the lowest obesity rates are: Colorado 101.6, Hawaii 95.6, Montana 103.4, California 95.5, and Massachusets 104.3 (highest IQ State). The average for these States being 100.08. So there is a 4 point IQ difference between the top 5 States with the highest and lowest percentage of obese people, which goes with the North/South gradient of higher IQ people living in the North and lower IQ people living in the South. Back in 2014, a California real estate group took 500,000 Tweets using a computer algorithm and estimated intelligence based on spelling, grammar, and word choice and found a difference in State by State intelligence. Notice how the further North you go the higher the average intelligence is, which is then correlated with the obesity levels in that State.

With poverty rates by State, we can see how the States in the South have less intelligent people in them which then correlates to the amount of obesity in the State. Though, there are some anomalies. West Virginia and Kentucky have a super majority of whites. This is easily explained by the fact that less intelligent whites live in those States, and since both the poverty rates and obesity rates are high, it follows that the State will be less intelligent than States that have more intelligent people and less obesity.

It is known that intelligence is correlated with obesity at around -.25 (Kanazawa, 2014). The negative correlation between intelligence and obesity means that they are inversely related so, on average, one with higher intelligence has less of a chance of being obese than one with lower intelligence. The States with the lowest IQ people having those with the highest BMIs corroborates this. In America, obesity rates by ethnicity are as follows: 67.3% for whites, 75.6% for blacks, and 77.9% for ‘Hispanics’.

Now that we know the average intelligence rates by State, the percentage of obese by State and the demographics by State, we can get into why obesity rates correlate with intelligence and race.

Diaz et al (2005) showed that minority populations are more likely to be affected by diabetes mellitus which may be due to less healthy diets and/or genetic factors. Using the National Health and Nutrition Survey for 1999-2000, they analyzed overweight, healthy adults, calculating dietary intake variables and insulin sensitivity by ethnicity. They characterized insulin resistance with fasted insulin, as those who are more likely to become insulin resistant have higher fasted insulin levels (levels taken after waking, with the subject being told not to eat the night before as to get a better reading of fasted insulin levels). Non-‘Hispanic’ whites had higher energy and fat intake while ‘Hispanics’ had higher carb intake with blacks having lower fiber intake.  Blacks and ‘Hispanics’ were more likely to have lower insulin sensitivity. However, ‘Hispanics’ were more likely to have lower insulin sensitivity even after controlling for diet, showing that metabolic differences exist between ethnicities that affect carbohydrate metabolism which leads to higher rates of diabetes in those populations.

Drewnowski and Specter (2004) showed that 1) the highest rates of obesity are found in populations with the lowest incomes and education (correlated with IQ), 2) an inverse relationship between energy density and energy cost, 3) sweets and fats have higher energy density and are more palatable (food scientists work feverishly in labs to find out different combinations of foods to make them more palatable so we will eat more of them), and 4) poverty and food insecurity are associated with lower food expenditures, lower fruit and vegetable intake, and lower-quality diet. All of these data points show that those who are poor are more likely to be obese due to more energy-dense food being cheaper and fats and sugars being more palatable.

Now that I’ve shown the relationship between race and IQ by state, obesity rates by state, insulin sensitivity by race, and that those in poverty are more likely to be obese, I can now talk about the actual CAUSE of obesity: insulin.

The conventional wisdom is that if you consume more kcal than you expend, you will gain weight, whereas if you consume less than your daily needs you will lose weight. This has been unchallenged for 50 years. Also known as Calories In and Calories Out (CICO), this mantra “eat less and move more!!!” has been bleated over and over with horrendous results. The CICO model only concerns itself with calories and not insulin which is a causal factor in obesity

In this study, participants in the basal insulin group which received the lowest average insulin dose gained the least average amount of weight at 4.2 pounds. Those on prandial insulin gained the most weight at 12.5 pounds. The intermediate group gained 10.3 pounds. More insulin, more weight gain. Moderate insulin, moderate weight gain. Low insulin, low weight gain.

Researchers compared a standard dose of insulin to tightly control blood sugars in type 1 diabetic patients. At the end of the 6 years, the study proved that intensive control of blood sugars resulted in fewer complications for those patients.

Though, in the high dose group, they gained on average 9.8 pounds more than those in the standard group.

More than 30 percent experienced major weight gain! Prior to the study, both groups were equal in weight. But the only difference was the amount of insulin administered. Were the ones given high levels of insulin all of a sudden more lazy? Were those who gained weight suddenly lacking in willpower? Were they lazier before the study? We’re they more gluttonous? No, no, and no!!



Finally, Henry et al (1993) took Type II diabetics and started them off with no insulin. They went from 0 units of insulin a day to 100 units at 6 months. As higher rates of insulin were administered, weight rose in the subjects. Insulin was given, people gained weight. A direct causal relationship (see figure above). However, what’s interesting about this study is that the researchers measured the amount of kcal ingested, the number of kcal ingested was reduced to 300 per day. Even as they took in less kcal, they gained 20 pounds! What’s going on here? Well, insulin is being administered and if you know anything about insulin it’s one of the hormones in the body that tells the body to either store fat or not burn it for energy. So what is occurring is the body is ramping down its metabolism in order for the subject to store more fat due to the exogenous insulin administered. Their TDEE dropped to about 1400 kcal, while they should have been losing weight on 1700 kcal! The CICO model predicts they should have lost weight, however, adaptive thermogenesis, better known as metabolic slow down, occurred which dropped the TDEE in order for the body to gain fat, as insulin directly causes obesity by signaling the body to store fat, so the body drops its metabolism in an attempt to do so. 

Putting this all together, blacks and ‘Hispanics’ are more likely to be in poverty, have lower intelligence, and have higher rates of obesity and diabetes. Furthermore, blacks are more likely to have metabolic diseases (adaptive thermogenesis aka metabolic slowdown is a metabolic disease) which are related with obesity due to their muscle fiber typing which leads to lower maximal aerobic capacity (less blood and oxygen get around the body). Type II skeletal muscle fibers’ metabolic profile contributes to lower average aerobic capacity in blacks. It also is related to cardiometabolic diseases, in my opinion because they don’t have the muscle fiber typing to run long distances, thus increasing their aerobic capacity and VO2 max.

Due to the diets they consume, which, due to being in poverty and having lower intelligence, they consume more carbohydrates than whites, which jacks their blood glucose levels up and the body then releases insulin to drive the levels glucose in the body down. As insulin levels are spiked, the body becomes insulin resistant due to the low-quality diet. Over time, even a change in diet won’t fix the insulin resistance in the body. This is because since the body is insulin resistant it created more insulin which causes insulin resistance, a vicious cycle.

Poverty, intelligence and race both correlate with obesity, with the main factor being lower intelligence. Since those with lower IQs have a lack of foresight into the future, as well as a lower ability to delay gratification which also correlates with obesity, they cannot resist low-quality, high-carb food the same way one with a higher IQ can. This is seen with the Diaz et al study I linked, showing that whites have higher levels of fat intake, which means lower levels of carbohydrate intake in comparison to blacks and ‘Hispanics’. As I’ve shown, those in poverty (code word for low intelligence) ingest more refined carbohydrates, they have higher levels of obesity due to the constant spiking of their insulin, as I have shown with the 3 aforementioned studies. Since blacks and ‘Hispanics’ have lower levels of intelligence, they have lower levels of income which they then can only afford cheap, refined carbs. This leads to insulin being constantly spiked, and with how Americans eat nowadays (6 times a day, 3 meals and snacks in between), insulin is being spiked constantly with it only dipping down as the body goes into the fasted state while sleeping. This is why these populations are more likely to be obese, because they spike their insulin more. The main factor here, of course, is intelligence.

Another non-CICO cause for obesity is exposure to BPA in the womb. Researchers carried out BPA testing in three differing subjects: 375 babies invitro, (3rd trimester) children aged 3 (n=408) and aged 5 (n=518) (Hoepner, et al, 2016). They measured the children’s bodies as well as measuring body fat levels with bioelectrical impedance scales.Prenatal urinary BPA was positively associated with waist circumference as well as fat mass index, which was sex-specific. When analyzed separately, it was found that there were no associated outcomes in body fat for boys (however it does have an effect on testosterone), but there was for girls (this has to do with early onset puberty as well). They found that after controlling for SES and other environmental factors there was a positive correlation with fat mass index – a measure of body fat mass adjusted for height, body fat percentage and waist circumference. The researchers say that since there was no correlation between BPA and increased obesity, that prenatal exposure to BPA indicates greater vulnerability in that period. The sample was of blacks and Dominicans from New York City. Whites drink less bottled water, which has higher levels of BPA. Blacks and ‘Hispanics’ consume more, and thus have higher levels of obesity.

In conclusion, blacks and ‘Hispanics’ are more likely to be in poverty, have lower intelligence, higher rates of obesity and lower incomes. Due to lower incomes, cheap, refined carbohydrates is what they can afford in bulk as that’s mostly what’s around poor neighborhoods. Ingesting refined carbohydrates more often consistently jacks up blood glucose which the body then releases insulin to lower the levels. Over time, insulin resistance occurs, which then leads to obesity. As I’ve shown, there is a direct causal relationship between the amount of insulin administered and weight gain. With the aforementioned factors with these two populations, we can see how the hormonal theory of obesity fits in perfectly with what we know about these ethnic groups and the obesity rates within them. Since people in poverty gravitate more towards cheap and refined carbohydrates, they’re constantly spiking their insulin which, over time, leads to insulin resistance and obesity.


Muscle Fiber Typing and Race: Redux

I recently blogged on Muscle Fiber Typing, HBD, and Sports. I showed that differences in which race wins at what competition comes down to ancestry, which then correlates with muscle fiber typing. I came across this paper, Black and White race differences in aerobic capacity, muscle fiber type, and their influence on metabolic processes, today which, of course, proved my point on muscle fiber typing.

The authors say that obesity is a known risk factor of cardiometabolic disease (though Blüher 2012 says that up to 30 percent of obese patients are metabolically healthy with insulin sensitivity on the same level as thin individuals) and that cardio can reduce excess adipose tissue (this isn’t true either), maintains weight (maybe) and reduces the risk of obesity (it doesn’t) and cardiometabolic disease (this is true). The two major determinants of aerobic capacity are muscle fiber typing and “the capacity of the cardiorespiratory system to deliver nutrient-rich content to the muscle”. As I said in my previous article on muscle fiber typing, depending on which fibers an individual has determines whether or not they are predisposed to being good at endurance sports (Type I fibers) or being good at explosive sports (Type II fibers). Recent research has shown that blacks fiber typing predisposes them to a lower overall VO2 max.

VO2 max comes down to a strong oxygen support system and the capacity to contract a large number of muscle fibers at once, both of which are largely genetic. Lactic acid makes us tired, the best way to train is to minimize lactic acid production and maximize lactic acid removal during exercise. High-Intensity Interval Training, or HIIT, achieves this. The more O2 consumed during exercise, the less of a reliance there will be on the anaerobic breakdown of CHO to lactic acid.

Along with inadequate exercise, these variables place blacks at an increased risk for obesity as well as other negative metabolic factors in comparison to other races/ethnic groups. The author’s purpose of the review was to show how skeletal muscle fiber typing contributes to obesity in non-“Hispanic” black populations.

The review indicates that the metabolic properties of Type II fibers (reduced oxidative capacity, capillary density, which is a physiological measure that takes a cross-section of muscle and counts the number of blood vessels within. The measurement can be considered an indicator of physical health and is also related to the ability to do strenuous activity) are related to various cardiometabolic diseases.

Since non-“Hispanic” blacks have more Type II fibers on average, they have a lower maximal aerobic capacity. Combined with low Resting Energy Expidenture (REE) and reduced hemoglobin concentration (hemoglobin is a protein in the red blood cells that shuttles oxygen to your tissues and organs and transports carbon dioxide from your organs and tissues back to your lungs), non-“Hispanic” blacks may be predisposed (they are when you look at what the differing skeletal muscle fibers do in the body and if you have a basic understanding of physiology) to a lower maximal aerobic capacity, which contributes to obesity and metabolic disease in the non-“Hispanic” black population.

I have written on ethnicity and obesity last year. In the two racial groups that were tested, American non-“Hispanic” whites and American non-“Hispanic” blacks, what the researchers say holds true.

On the other hand, Kenyans have an average BMI of 21.5. Since we know that a high VO2 max and low BMI are correlated, this is why Kenyans succeed in distance running (along with VO2 max training, which only enhances the genetic effects that are already there).

Moreover, I wrote an article on how Black American Men with More African Ancestry Less Likely to Be Obese. How do we reconcile this with the data I have just written about?

Simple. The population in the study I’m discussing in this article must have had more non-African ancestry than the population that was gathered showing that black American men with more African ancestry are less likely to be obese. The researchers in that study looked at  3,314 genetic markers. They then tested whether sex modifies the association of West African genetic ancestry and body mass index, waist circumference, and waist to hip ratio. Also, they adjusted for income and education as well as examined associations of ancestry with the phenotypes of males and females separately. They conclude that their results suggest that a combination of male gender and West African ancestry is correlated with protection against central obesity and suggests that a portion of the difference in obesity (13.2 percent difference) may be due, in part to genetic factors. The study also suggests that there are specific genetic and physiologic differences in African and European Americans (take that, race-denialists =^) ).

Since both black men and women in America share the same environment, some genetic factors are at play in the differences in obesity rates between the two sexes with more African ancestry for black American men being the main reason.

Finally, I wrote an article on BPA consumption and obesity. The sample was on blacks and Dominicans (they’re black as well) in NYC. It was discovered that babes who were exposed to BPA more in childhood and in the womb had higher chances of being obese. This goes with what the authors of the study I’m citing in this article say. There are numerous environmental factors that pertain to obesity that’s not kcal in/out (which the First Law of Thermodynamics is irrelevant to human physiology). BPA consumption is one of them (as well as a cause for the current and ongoing cucking of Europe). Whites at all age groups drink more tap water. Blacks and ‘Hispanics’ were pretty much even in consumption of bottled water. Bottled water has BPA in the plastic, and since they drink more bottled water, they run the risk of their children being more prone to obesity due to the negative effects of BPA in the human body.

In sum, blacks are more likely to be faster due to their fiber typing, but are also more likely to be obese (in this sample, anyway which I assume was a mix of men and women. I will update this article when I find and read the full paper). They also run a higher risk of having related diseases, most notably due to a lower REE (showing they don’t walk around as much, since too much sitting increases mortality EVEN WITH EXERCISE. So if you have a desk job and don’t do any other physical activity and enjoy living, do more LISS, low-intensity steady-state cardio). These factors also, in part, explain why blacks have higher rates of hypertension (with Sickle Cell Anemia being another cause since when the blood is sickle-shaped, they crowd in the blood vessels causing blockage in the veins which leads to strokes and other diseases). The more the genetic factors that predispose people to obesity are understood (let’s be real here, there ARE genetic correlates with obesity), the better we can help those who suffer from the condition.

Black American Men with More African Ancestry Less Likely to Be Obese

1300 words

Black American men are the least likely male ethnic group to be overweight or obese in America (69.2 percent) compared to ‘Hispanic’ men (78.6 percent) and white men (71.4 percent) (Ogden et al, 2014). As a result of being less likely to be obese, black men as a whole suffer from diabetes and other diseases that are correlated with higher body fat. Conversely, for women the rate for white women is 63.2 percent, 77.2 percent for ‘Hispanic’ women and 82.4 percent for black women. Why do black men have lower rates of obesity and chronic health diseases?

Klimentidis et al (2016) set out to find why black men have lower rates of obesity than black women despite having the same socioeconomic and environmental factors. Using 2814 self-identified African Americans from the Atherosclerosis Risk in Communities study, they estimated each individual’s degree of African ancestry using 3,314 genetic markers. They then tested whether sex modifies the association of West African genetic ancestry and body mass index, waist circumference, and waist to hip ratio. Also, they adjusted for income and education as well as examined associations of ancestry with the phenotypes of males and females separately. They recreated their results with the Multi-Ethnic Study of Atherosclerosis (n= 1611 AA).

They discovered that West African ancestry is negatively correlated with obesity as well as central obesity, which is obesity around the midsection, among black men but not black women. Also noted, was that black men with more African ancestry had a lower waist to hip ratio and less central adiposity than black men with less African ancestry. They conclude that their results suggest that a combination of male gender and West African ancestry is correlated with protection against central obesity and suggests that a portion of the difference in obesity (13.2 percent difference) may be due, in part to genetic factors. The study also suggests that there are specific genetic and physiologic differences in African and European Americans.

This study confirms two things. 1) Black women are more likely to be obese than black men as well as the general population. 2) Black men have less of a chance of becoming obese or overweight as well as less of a chance of incurring the risks that come along with being obese or overweight. The degree of African ancestry is the cause in both black men and black women for these differences in the rate of overweight and obese individuals in both populations. One of my theories also got confirmed. Since obesity is partly genetic in African Americans, and black girls have an earlier menarche (period) than white girls due to higher body fat which activates the hormone leptin, which precedes an increase in body fat to prepare for eventual menstruation, I theorize that black girls have earlier menarche than white girls due to r/K Selection Theory. It’s an evolutionary advantage to be able to have children earlier, as the population dies younger.

Evolutionarily speaking, black men needed to be more fit in order to protect the clan from predators. This is also why blacks evolved narrower hips (Rushton, 1995). Higher body fat allows for more protection for a baby in vitro, which is why an increase in leptin precedes an increase in body fat, which then causes black girls to have an earlier puberty.

One of the questions I would like answered is whether it’s the actual degree of African ancestry that is the cause of black men being less likely to be obese or it’s the cause of higher degree of European ancestry. European American men do have a slightly higher risk of being overweight or obese than African American men, so there is some credence to this hypothesis. Three SNPs were found to be correlated with obesity in African American populations as well as European American populations; this could be one cause.

Wagner and Heyward (2000) discovered biological differences exist between blacks and whites. They reviewed the literature on the differences between blacks and whites in fat-free body mass (water, mineral, and protein) fat patterning and body dimensions and proportions. Blacks, in general, have greater bone mineral density and body protein content than do whites, resulting in lower fat-free bone density. They also note racial differences in the differences of subcutaneous body fat, which is the body fat that’s just below the skin, as opposed to visceral body fat which is found in the peritoneal cavity, which can be measured with calipers to give a rough estimate of total body fat adiposity. The conclusion reached in the study was that differences in FFB (fat-free body) was statistically significant between blacks and whites. They also have a greater BMC (bone mineral content) and BMD (bone mineral density) than do whites. They also argue that for a given BMI (body mass index), blacks might have less adiposity because they tend to be more mesomorphic. Researchers push for the development of racial-specific equations to better see differences in FFB.

With the above study noting that there is a substantial difference between blacks and whites in FFB, there may be some truth to a negative effect of European ancestry on blacks in terms of obesity acquisition. However, lower FFB in black men is one reason why black men can’t swim as well as whites.

One of the causes for both racial and gender discrepancies in obesity is genetic in origin. The difference between black men and black women is 13.2 percent whereas for white men and white women the difference is 8.2 percent. There is a clear genetic difference between races that is the cause for this discrepancy. Black men and black women have the same socioeconomics status and live in the same environment, so some of the differences in obesity noticed in this population must be genetic in origin.

Freedman et al (2004) observed that, as expected, black men were more likely to choose heavier figures as an ideal body for women than white men. Also expected was that both groups would choose figures with a low waist to hip ratio, but black men would choose a lower waist to hip ratio as ideal. They also show weight to be a more important cue than waist to hip ratio in mate selection as well as supporting the theory that black men’s preferences may serve as a protective factor against eating and body image pathology in black women.

To give an example of the above study in action, we can look at Mauritania. They force feed their women up to 16,000 kcal a day in an effort to make them obese, as that’s what is seen as attractive in their society. Mauritanian love songs also describe the ideal woman as fat. Obesity is so celebrated in their society that parents beam at the fact that their daughters look obese, as they have a better chance of getting partners.

The higher the degree of West African ancestry in black men, the lower the chance they have for obesity. I do wonder, though, if it’s because they have less European ancestry or because they have more African ancestry. Black men with more African ancestry are less likely to be obese than black men with less African ancestry, so there is a correlation there that I would like to see explored in the future. Differences in fat-free body mass have been noticed between blacks and whites, but this is one of the first studies to my knowledge that shows that genetic differences between black men and black women may be part of the cause for obesity differences in that population. Cultural differences in perception of beauty, of course, come into play in regards to differences between black and white men, however, the cause of black women having higher rates of obesity is due in part to genetic factors, which then leads to black men liking that as their beauty standard.

Science Daily: Mom’s Exposure to BPA During Pregnancy Can Put Her Baby on Course to Obesity

1750 words

Science Daily came out with an article today that exposure to BPA invitro for babies is correlated with obesity at age 7. 94 percent of the women tested had detectable levels of BPA. BPA is also linked with early onset puberty, which I will also speak on later in this article as it has implications for one of my theories.

I briefly touched on BPA in my article What’s the Cause of the Cucking of Europe? where I said:

I advise all of you (women included, there are many deleterious effects of BPA on the mother as well as the baby prenatally), to discontinue use of plastics with BPA in them.

The above-linked study shows that preeclampsia is correlated with elevated levels of BPA in the blood levels in the pregnant mothers, fetal blood, and the placenta. BPA was found to be elevated in mother’s fetal tissue with preeclampsia in comparison to the mothers with lower levels of BPA in their fetal tissue. I will come back to the BPA link with preeclampsia later in the article as it has implications for ethnic groups in America.

The paper, which was just released on the 17th, called Bisphenol A and Adiposity in an Inner-City Birth Cohortcarried out tested BPA in three differing subjects: 375 babies invitro, (3rd trimester) children aged 3 (n=408) and aged 5 (n=518) (Hoepner, et al, 2016). They measured the children’s bodies as well as measuring body fat levels with bioelectrical impedance scales.** Prenatal urinary BPA was positively associated with waist circumference as well as fat mass index, which was sex-specific. When analyzed separately, it was found that there were no associated outcomes in body fat for boys (however it does have an effect on testosterone), but there was for girls (this has to do with early onset puberty as well). They found that after controlling for SES and other environmental factors, they discovered that there was a positive correlation with fat mass index – a measure of body fat mass adjusted for height, body fat percentage and waist circumference. The researchers say that since there was no correlation between BPA and increased obesity, that prenatal exposure to BPA indicates greater vulnerability in that period.

The researchers then conclude that BPA exposure invitro “may be an important underlying factor in the obesity epidemic” and that “Endocrine disrupting chemicals like BPA may alter the baby’s metabolism and how fat cells are formed early in life.”

If true, this has huge implications for the way we look at the obesity epidemic in this country. Who are the most likely to be obese? “Hispanics” and blacks (Ogden et al, 2014).

Returning to what I brought up earlier about early onset puberty: in my article on the hormone leptin being a cause for earlier menarche in black girls, I noted that since black girls were more likely to be heavier as well as mature faster than white girls, that differences in leptin were the cause of differences in menarche between the two groups.  Elevated levels of serum leptin were correlated with body fat and differences in maturation between the two groups. Differences remained, but lessened, after controlling for differences in fat mass, maturation, age, and physical fitness.

Since BPA is correlated with adiposity in children and black girls have earlier menarche DUE to there being a higher chance of black girls being overweight in comparison to white girls, BPA is yet another piece to the puzzle of this phenomena, along with, of course, evolution. Ingestion of BPA is an environmental factor, however, with these changes in body chemistry in the children invitro due to increased BPA consumption by the pregnant mothers, it leads to one cause that can be prevented from further occurring due to our new knowledge.

The study was carried out on a cohort from NYC. In 2010 in NYC, the city was: 44 percent white, 25.5 percent black, 12.7 percent Asian with the rest being filled out by ‘Hispanics’ (not a racial category) and mixed-race people. Even after they matched for SES and other environmental factors, these differences persisted. However, this study was only carried out on those women who self-identified as either Dominican (basically African) and black. To quote the researchers:

Women were included if they self-identified as either African American or Dominican and had resided in Northern Manhattan or the South Bronx for at least 1 year before pregnancy. Exclusion criteria included mother’s report of: cigarette smoking or use of other tobacco products during pregnancy, illicit drug use, diabetes, hypertension, known HIV, or a first prenatal visit after the 20th week of gestation.

So, we have a full sample of Caribbean Africans and African Americans in this study. What else can we learn about those two populations and their consumption of things with BPA in them?

race differences tap and bottled water

The above Figure (7) is taken from the U.S. Department of Agriculture and the Food Surveys Research Group study on differences in drinking tap and bottled different populations in the country. As you can see in this figure (what is notable is the ages 12-19 and 20 to 60 in the table), whites at all age groups drink more tap water. Blacks and ‘Hispanics’ were pretty much even in consumption of bottled water. However, Mexican American girls, like black girls, are also entering puberty earlier. Since both populations have a substantial percentage of them overweight and obese (factor for serum leptin production which then causes early onset puberty), this again shows a strong correlation between body fat gain and early onset puberty. Moreover, this also shows that both Dominican and black populations consume more bottled water than do white populations, both populations are more likely to be obese or overweight (even after controlling for SES) which causes leptin production earlier causing periods to happen much sooner than in populations who drink less bottled water and use other products with BPA in them. .

Going back to preeclampsia, it is a condition that pregnant women develop that’s characterized by hypertension (high blood pressure) and protein in the urine. It’s known that black women suffer from it the most. More interestingly, over the past ten years, rates of preeclampsia have been increasing in the black female population. As the researchers note in the article, BPA is correlated with preeclampsia. Blacks have a higher rate and chance of being diagnosed with hypertension as well. All of these differing variables coalesce into our current obesity epidemic. With blacks and “Hispanics” being more likely to be overweight/obese drink more bottled water, have a higher risk for hypertension, higher risk for preeclampsia and having earlier menarche, these help explain, in part, racial/ethnic differences in obesity.

These differences can be attributed to consumption of bottled water, i.e., consuming things with made with and packaged in plastic as well as canned foods. From my experience with Dominican and black New Yorkers, they tend to have horrible lifestyles, tend to drink tons of bottled water and also tend to be overweight or obese at a higher rate in comparison to the general population. This leads to biologic factors changing (i.e., earlier menarche in younger girls) in these young girls, leading to devastating effects on their body chemistry.

This study, yet again, proves another underlying factor for obesity in certain populations in the country. And what do you know? It’s the populations that already have the highest rate of obesity in the country. When it becomes definitive that BPA consumption by pregnant mothers does lead to underlying factors in obesity. To quote the researchers: “Endocrine disrupting chemicals like BPA may alter the baby’s metabolism and how fat cells are formed early in life.” This will be HUGE for our understanding of underlying causes to obesity! Moreover, if (when) this is fully corroborated, it can then be said that by mothers exposing their children in the womb to excess levels of BPA, there is a chance that they are “giving their own choice to make their children have a higher chance of being obese, as they know the dangers of BPA consumption during pregnancy and all of the negative variables associated with it.”

This is an extremely interesting and important study for our understanding of obesity. Since BPA consumption invitro is correlated with higher fat mass index in girls at age 7, and since those girls who tend to be more overweight and obese than other populations, we can then say that BPA has a hand in obesity in children, which then causes serum leptin to be released, causing way menarche in these populations. An increase in sexual maturation has been linked to the obesity epidemic, which began around 60 years ago. The cause of this is due to the demonization of the fat macro and carbohydrates, all the while it was reversed. This destroyed insulin sensitivity for many Americans, leading to a huge majority of our health problems today.

In conclusion, underlying factors for obesity keep appearing. Due to racial/ethnic differences in bottled water consumption (one of the most common BPA products in households), which the effects of BPA may alter how fat cells are formed in early life, this accounts for, in part, excess adiposity in differing populations. These underlying factors could help show where some of these racial/ethnic differences in obesity come from. Since the two populations in the study (black American and Dominican) both have high levels of adiposity, both drink a lot of bottled water and both have earlier menarche than do whites (who drink LESS bottled water), this shows that some (a lot?) of the variation in obesity between ethnic/racial groupings can be explained by these underlying factors.

** I have one problem with this study. They assessed fat mass index with bioelectrical impedance.The machine sends a light electrical current through the body and measures the degree of resistance to the flow of the current, which body fat can then be estimated. Problems with measuring body fat this way are as follows: it depends on how hydrated you are, whether you exercised that day, when you last ate, even whether your feet are calloused. Most importantly, they vary depending on the machine as well. Two differing machines will give two differing estimates. This is my only problem with the study. I would like if, in a follow-up study, they would use the DXA scan or hydrostatic weighing. These two techniques would be much better than using bioelectrical impedance, as the variables that prevent bioelectrical impedance from being a good way to measure body fat don’t exist with the DXA scan or hydrostatic weighing.

Leptin and its Role in the Sexual Maturity of Black Girls

1200 words

There are differences between the races in regards to sexual maturity. I’ve recently discovered that leptin plays a role in black female teenagers and how they reach puberty earlier than that of white women. This is one out of many variables that prove Rushton’s three-way rule; that the races all differ on certain variables, on average.

Buried in the middle of this article on black and white differences in body composition, it is observed that the mean concentration of leptin was significantly greater in black girls than that of white girls. The authors conclude that leptin may play an important role in the accelerated growth and sexual maturation of black girls:

In one study, the mean leptin concentration was significantly (P < 0.01) higher in 57 black girls (15.0 ± 10.1 μg/L) than in 79 white girls (8.4 ± 11.1 μg/L) aged 8–17 y (58). The authors concluded that this difference might play an important role in the accelerated growth and sexual maturation of black girls. Likewise, Nicklas et al (57) reported a strong correlation between leptin and %BF for both black (r = 0.71, P < 0.0001) and white (r = 0.61, P < 0.001) obese postmenopausal women, but a significant racial difference in leptin concentration (36.0 ± 4.8 compared with 45.8 ± 3.5 μg/L; P < 0.05), respectively. Additionally, leptin correlated with resting energy expenditure in black women (r = 0.58, P < 0.001) but not in white women (r = 0.08).

Also noticed, was that leptin correlated with REE (resting energy expenditure) in black women but not in white women.

Wong et al (1998), state that because African-American girls tend to be heavier and mature faster than white girls, then there must be a leptin difference between the 2 groups. He measured serum leptin concentrations in 12 hour fasted blood samples of 57 black and 79 white girls. Body comp was measured by x-ray absorptiometry, sexual maturity by doctor examination and physical fitness by treadmill testing. What was found was the serum leptin levels were positively correlated with body fat, maturation and insulin were higher in the black girls after controlling for age. Differences remained, but lessened, after controlling for differences in fat mass, maturation, and physical fitness. This is more proof that leptin is a cause for the role in earlier sexual maturity in black girls.

Kaplowitz (2008) observed in his paper Link Between Body Fat and the Timing of Puberty that several studies have shown that the increase in earlier sexual maturation may indeed be linked to the obesity epidemic which started to rise around 50 to 60 years ago when fat was demonized as “being the cause for fat gain”, all the while carbs were championed as a better macro over fat. Of course, we now know that’s not true, but the implications of this lie that we’ve been told are now coming out in the light 50 years later.

Kaplowitz states that the evidence currently out points to obesity being a cause for earlier puberty in girls, rather than earlier puberty causing an increase in body fat (hmmm.. where have I heard confusing one cause for another before? Oh yeah, the IQ/obesity cause).Many studies have come out that show, in both rats and humans, that leptin may be the critical link between body fat and earlier puberty. Both mice and humans who were deficient in leptin both failed to reach puberty unless leptin was administered. Though he says that leptin may end up playing a permissive, rather than a critical metabolic signal that initiates puberty. But with the data of black girls having higher leptin levels, leptin being correlated highly with body fat, and both being highly correlated with increased sexual maturation show the reason why black girls are a) more sexually active at a younger age and b) why black girls mature faster than white girls. He finally concludes that it makes evolutionary sense that body fat and reproduction in girls evolved as a mechanism to ensure that pregnancy won’t occur unless adequate levels of body fat are had.

This is yet more biological evidence for physiological differences between the races.

When fat mass increases, so do leptin levels. When leptin levels increase, puberty happens earlier. Black girls have higher rates of  leptin, which correlates highly with body fat and sexual maturity, so it’s no surprise that we see these factors here.

What are evolutionary causes for this? Well, seeing Africa’s life expectancy, the rate of parasitic load as well as disease in Africa, and Rushton’s r/K Life History Theory, which states that those more r selected will have more children and show less care for them whereas those more k selected will have less progeny, but show more care, we can easily see how such a mechanism evolved. With IQ being highly correlated with life expectancy (at .95), we can see part of the reason why, for instance, black women evolved to have higher rates of 2 egg twinning in comparison to whites (16 per 1000 for blacks, 8 per 1000 for whites and 4 per 1000 for Orientals). To quote Rushton from Race, Evolution, and Behavior:

Black women, compared to white women, average a shorter period of ovulation and produce more eggs per ovulation in addition to all the other characteristics in Table 1.1. As mentioned, the rate of dizygotic twinning, a direct index of egg production, is less than 4 per 1,000 births among Mongoloids, 8 per 1,000 among Caucasoids, and 16 or greater per 1,000 among Negroids. (pg. 6)

This is a clear evolutionary strategy. Have more children where it’s less hospitable and there is a higher mortality rate, especially for young children and have fewer children where it is more stable and less environmental dangers are around.

Even more evidence to bolster my claim is how 82 percent of black women are overweight or obese (Ogden et al, 2014). Genes related to obesity have also been found in African-Americans, as well as European-Americans, which also bolster the claim seeing as the genes were found to do the same things in both populations. To quote myself from the above article:

In a study published back in 2013, researchers were looking for obesity genes in African Americans. The study, which involved more than 70,000 men and women of African descent, they were able to identify 3 SNPs that were associated with obesity and BMI in the sample population. What was also found, was that those same genetic sequences also heighten rates of obesity in peoples with no African ancestry, all of the genetic variants associated with obesity were also found in European populations. The same genes found in African populations did the same in European populations, and vice versa.

To quote the paper:

We provide evidence for a shared genetic influence on BMI across populations, as we found directionally consistent associations with the majority of known BMI risk variants. This observation suggests that bioloically functional alleles are ancient and probably arose before migrations out of Africa. In addition, we were able to refine the window of association of some of the previously established BMI loci, which may eventually help identify the biologically functional variant(s).

BMI is also between .75 and .82 heritable. These factors show yet another cause for black women’s high obesity rates, of course with eating garbage food all of the time, but I’m talking about evolutionary reasons.

There are reasons why black girls mature faster than white girls, it’s because of leptin, which precedes an increase in body fat to prepare for eventual menstruation and higher body fat helps to protect the baby in vitro. R/K Life History Theory then shows the evolutionary reasons why earlier sexual maturity happens for black girls over white girls: lower life expectancy.

Is There Bias in Mental Testing?

1400 words

Many people who are uneducated about the matter of cognitive abilities tests may say certain things such as “IQ tests are biased towards white males”.”IQ tests don’t test anything of worth” or “IQ is just a number and doesn’t mean anything in life”. All of these are untruths. I will show in this article how and why those aren’t true, as well as showing that IQ is one of the best predictors of success in life.

“IQ Tests Are Biased Towards White Males”

This is my favorite one from IQ deniers. They seem to think that by saying tests are biased towards white males, especially those from the West, that it will invalidate over 100 years of IQ testing and any and all racial gaps concerning them. It doesn’t work like that.

Many deniers may say “They’re (IQ tests) biased towards white males because there are certain words on the test that underprivileged peoples don’t get to learn”. They may say that due to IQ tests having certain words on them that aren’t taught to them in their environments, that they’re biased and don’t accurately assess black American’s intelligence.

But Charles Murray and Richard Herrnstein say in The Bell Curve that those words that only a privileged person would know, which, if I remember the example from the book correctly was something to do with yachts, was removed from IQ tests decades ago, so those points are moot whenever someone brings them up.

If IQ tests were biased towards white males, then why do Ashkenazi Jews score between 107-115Why do Indian American Immigrants score 112Why do East Asians score 106?(pg 236) These are questions that people never seem to answer, because it seems that all they were told is that the tests for cognitive ability are biased towards the majority, when no matter where IQ tests are carried out on East Asians, Ashkenazi Jews and Indian immigrants, they score higher than whites every time. How is that explained by a test bias towards the ones it was supposedly invented to assess who was superior in intelligence?

Two years after The Bell Curve came out, a paper was published called Mainstream Science on Intelligencewhich corroborated the findings in The Bell Curve. To quote from the publication:

Intelligence tests are not culturally biased against American blacks or other native-born, English-speaking peoples in the U.S. Rather, IQ scores predict equally accurately for all such Americans, regardless of race and social class. Individuals who do not understand English well can be given either a nonverbal test or one in their native language.

Right here, from the publication from 52 signatories from the leading researchers in the field of intelligence all say that IQ tests are not culturally biased at all to those who don’t speak the language, which of course means non-white populations as well as white populations who don’t speak English.

If they were biased towards white males, then we can say that if we put those from different races into white homes, test their IQs at the beginning of the study, and assess IQ at adulthood, we’d be able to see if it was true, if IQ tests were really biased against other races. Well, the Minnesota Transracial Adoption Study happened (pg 256), and the SD gap literally stayed the same at 1.2 SDs.

What the Minnesota Study also tells me is this: it’s clear as day that black mothers are not conducive to an intellectual environment. Why, if black mothers were, would they need to be taken out as a variable and have the black kids be raised by white women? That, in my opinion, should end the debate right there. Seeing as the mother’s IQ is the best predictor of the child’s. Those mixed-race white and black kids with white mothers have higher IQs than those with black mothers. Because the prenatal environment is important to a developing and growing fetus. This should end the debate right where it is, but instead, we still have people who want to push that IQ tests are biased towards white males, which I have shown that it’s not the case at all.

Finally, to quote from the paper Intelligence: Knowns and Unknowns, which was funded by the APA Taskforce, headed by Neisser:

Considered as predictors of future performance, the tests do not seem to be biased against African Americans.

“IQ Tests Don’t Test Anything of Worth”

This is another denialist tactic that those who wish to deny the worth of the IQ test. What they measure are short-term memory, verbal ability, analytical thinking, mathematical ability and spatial reasoning. How anyone can believe that they don’t test anything of worth, even after hearing about what it does test is beyond me. I touched on success in life in regards to IQ in this article. IQ tests do mean a lot to life success, along with personality traits (coming in a future post).

There isn’t that high of a correlation with IQ and monetary success (around .33), so you’re going to find those who have high IQs and not have attained a lot of wealth, whereas you’ll also find those with lower IQs who have attained wealth, due in part to certain personality characteristics, all of which are at least 50 percent heritable.


The table above (pg 322, The Bell Curve), shows how after controlling for IQ (IQ 100), that blacks and Hispanics have substantially higher probabilities than whites of being in high IQ occupations (which I would reason that’s due to Affirmative Action).


(pg 323) After controlling for IQ, wage differences almost disappear! If America were so racist, why then, do blacks and ‘Latinos’, who are matched for IQ, then make the same amount of money? Almost as if IQ is one of the best predictors of monetary success in life.



(pg 326) After controlling for IQ, poverty differentials decrease by three-quarters for both ethnic groups. Why is that? Because, as I’m showing with all of these examples, when matching for IQ, gaps substantially shrink, disappear entirely or have those ethnic groups actually have more success than whites when matched for IQ, proves that IQ is one of the most important things in life, due to those with high IQs being able to reason better than those with lower IQs.


(pg 338) This is one of my favorites. Because we know that average IQ for a criminal is 85, even after all variables are controlled for, the IQ for criminals is still at 85, showing that low cognitive ability is a cause for being incarcerated as well. Showing that the gap disappears by almost three quarters shows, in my opinion, that the remaining incarcerated blacks may have the 2-repeat MAOA-L gene, as well as higher testosterone, are the cause for the remaining quarter who do get incarcerated.

Clearly, IQ tests are so biased that they show all of these things disappear or even reverse with certain variables when IQs are matched at 100 with ethnicity.

So to those who say “IQ is just a number which doesn’t mean anything in life”, you’d have to explain how these things happen when matched for IQ. Did those who get high scores not feel the effects of so-called white supremacy?

I’m sure we’ve heard of the B.I.T.C.H. IQ test before. Which supposedly tests ‘black cultural homogeneity’, but it’s just nonsense, as evidenced by:

Shucking means:

Stone fox means:

T. C. B. means:

“Bo Diddley” is a:

Hattie Mae Johnson is on the Country. She has four children and her husband is now in jail for non-support, as he was unemployed and was not able to give her any money. Her welfare check is now $286 per month. Last night she went out with the highest player in town. If she got pregnant, then nine months from now how much more will her welfare check be?

“Money don’t get everything it’s true.”

These are all actual questions on this ‘so-called IQ test’. What a joke right?

Those who say that  IQ tests are biased towards white males, or anyone affluent for that matter, have no idea what they’re talking about. None of what they say has any basis in fact and is clear wishful thinking. If IQ tests were so biased, other races/ethnicity wouldn’t score higher than whites. If IQ tests were so biased, why would those blacks and ‘Latinos’ who score at 100 show certain gaps closing, closed and even had an advantage over whites when matched for IQ (which was due in part to Affirmative Action, obviously)?

Those who say that IQ tests are biased are true ideologues and those views have no basis in reality.

For those who are interested, Arthur Jensen wrote a whole book on this subject.

Refuting Robert Sternberg’s Triarchic Theory of Intelligence

2000 words

I came across this video today from commenter Animekitty on PumpkinPerson’s blog. Animekitty says:

I just happen to think that practicality could be considered a for of intelligence. And that maybe Africans have a form of practicality that is different than the practicality of whites.

Which, as Sternberg explains in the video, sounds a lot to me like visio-spatial intelligence.

His basic thesis is that differing cultures have differing ways in which they quantify intelligence. I will use the examples he uses in the slides in the video.

First, he brings up differing examples of the models of the relationship between culture and intelligence. He brings up Herrnstein and Murray’s model of intelligence, stating that if you want to do a cross-cultural study of intelligence, you would translate the tests of WISC scores between different cultures.

A second model is like Nisbett’s. Using the same translated tests, but the same tests might be involved with different structures and different processes. He says that in Nisbett’s model, differing cultures will see the same things in a differing way, i.e., someone from Asia will what you may see as the background, they may see as the foreground and vice versa.

The third model which Sternberg uses is that there is a common form of intelligence, meaning they have to see what is going on in their lives. Defining their problems, mentally represent them and then allocate resources for a solution, set up a strategy, solve it and model it after your solution. He says the tests you would use would differ in the age of the person.

In model four which is the extreme end of model 1, is that everything is relative. The structures and processes of intelligence and structures are different. Basically, wherever you go you have to start over with different tests between cultures.

  1. Children and adults may be able to do tasks in one cultural/biological context but not in another.

He cites the Nunes study, where Nunes noted that Brazilian street children show that in one context, kids could do the math on the street, but giving them the same thing in a different context, they can’t solve the problems.So it suggests what would seem to be a test depends on the given context.

This was also noted in a study by Lave (1988), who had housewives wherein they were given math problems in the supermarket and were able to do them correctly, but gave differing answers under a different situation.

Some good evidence here. This could also be used as evidence that ‘women aren’t really all that bad at math’. There is currently no evidence to support or refute his theory, but I’m pretty sure I can show where his thinking is due to renaming of processes that we already know.

2. Students may develop contextually important skills at the expense of academic ones.

He cites the study: The Relationship between Academic and Practical Intelligence: A Case Study in Kenyain which he says:

We suggest that, among these villagers, time spent developing academic skills may be perceived as taking away from time that needs to be spent developing practical skills and vice versa. The result is that academic and practical intelligence can develop independently or even at odds with one another.

Seeing as those academic skills correlate highly with a nation’s success or lack thereof, it’s clear that they don’t have the brain power to understand academic things, and therefore gravitate towards something they can understand with their lower IQs.

He then references a study on Kenyan children in a village called Luo. They collected 91 plant remedies from mothers and found that it was shared knowledge that the elders also knew, as well as the children. They’re able to memorize a lot of natural remedies to combat parasitic diseases. He uses this study to say that intelligence is dependent on cultural contexts, and therefore cannot be measured between cultures due to differing definitions of intelligence in those certain cultural contexts.

He says that in our societies, knowledge of natural remedies has no basis in our society. Conversely, those children in Nigeria have to worry about surviving and not school. So Sternberg says that in their cultural context, intelligence is knowing natural remedies to parasitic diseases.

This next part made me laugh. One of the questions on the test was:

“A small child in your family has Homa. She has a sore throat, headache and fever. She has been sick for three days. Which of the following Yadh Nyaluo (Luo herbal medicines) can treat Homa?

i. Chamama. Take the lead and sniff fito (medicine up to nose to sneeze out the illness.)

ii. Kaladali. Take the leaves, drink and fito.

iii. Obuo. Take the leaves and fito.

iv. Ogaka. Take the roots, pound and drink.

v. Ahundo. Take the leaves and fito.

This reminded me so much of the B.I.T.C.H. IQ test (yes, that’s the real name). There are ridiculous questions such as:

“Alley Apple is”

“”I know you, shame” means”

“Main Squeeze means”

“A “handkerchief head” is:”

Which are ridiculous questions in terms of an IQ test. When people say that tests are ‘culturally biased’, I don’t think they mean to use complete gibberish and bastardizing the English language to show that there is a ‘cultural bias’ with IQ tests. There isn’t. Even then, Raven’s Progressive Matrices eliminates any so-called ‘cultural bias’.

Those questions are ridiculous and have nothing to do with intelligence. Of course if you use differing variables for all cultures/societies, you will say hey!! Everyone is smart, no one is dumb! Which has no basis in reality.

3. Students have substantial practical skills that go unrecognized in academic tests.

He cites a study done on a Yup’ik Alaskan community, in which he says that differing peoples will have differing academic and practical skills.

He shows a question from that test, which is similar to the one I have shown above about the Yup’ik villagers. He says that the point is, is what’s hard is in the context of how you grew up. That those who grew up in rural areas would know the answer to the question in comparison to those from urban areas. They found that urban students outperformed Yup’ik students on academic tests. But Yup’ik children outscored urban children on the Yup’ik intelligence test. The urban kids do better on the academic tests, where the Yup’ik kids do better on the practical intelligence tests. He says you have to know certain things for your certain environment you’re in.

The findings were that academic intelligence modestly predicted adaptive skills but not hunting skills in the urban and rural communities. On the other hand, practical intelligence modestly predicted adaptive skills and moderately predicted hunting skills in the rural communities but not the urban ones.

He says the Yup’ik kids know how to get from point A to point B that might be 100 miles away in the tundra in the winter and they’ll get there. If the teachers tried to do the same, they’d die. The kids have this tremendous skill set relative to their environment. To succeed in their textbooks, you don’t need to do those certain things in their environment.

This reminded me of the Inuit. They have the same brain size as East Asians, due to being one of the peoples from one of the 3 migrations from Siberia into the Americas, but they only have a 91 IQ despite living in one of the coldest climates in the world. Richard Lynn attributes this to them having a small population. Those who have bigger populations have more chance for certain mutations to arise and be selected for. People have marveled at their ability to track where they were and how they got around the tundra. This is visio-spatial ability at work.

It seems like he’s trying to say that there no fit or unfit individuals for any given environment, only what is defined as ‘intelligence’ is different in each society, but as I am showing you, they all go back to the factor, or general intelligence.

4. Practical intellectual skills may be better predictors of health than academic ones.

Wrong. He says that practical intelligence is different in different places. Practical intelligence is just as good as academic intelligence in terms of health in his eyes.

Whatever the case may be, actual g, is one of the best predictors of your longevity in life.

5. Teachers evaluations of students are constrained by their concepts of intelligence.

He cites his study Intelligence and culture: how culture shapes what intelligence means, and the implications for a science of well-being. In which he says:

It is important to realize, again, that there is no one overall US conception of intelligence. Indeed, Okagaki & Sternberg (1993) found that different ethnic groups in San Jose, CA, had rather different conceptions of what it means to be intelligent. For example, Latino parents of schoolchildren tended to emphasize the importance of socialcompetence skills in their conceptions of intelligence, whereas Asian parents tended rather heavily to emphasize the importance of cognitive skills. ‘White’ parents also emphasized cognitive skills more. Teachers, representing the dominant culture, emphasized cognitive skills more than social-competence skills. The rank order of children of various groups’ performance (including subgroups within the Latino and Asian groups) could be perfectly predicted by the extent to which their parents shared the teachers’ conception of intelligence. In other words, teachers tended to reward those children who were socialized into a view of intelligence that happened to correspond to the teachers’ own. However, social aspects of intelligence, broadly defined, may be as important as or even more important than cognitive aspects of intelligence in later life. Some, however, prefer to study intelligence not in its social aspect, but in its cognitive one.

With the ‘Latino’ mention, he’s describing verbal intelligence, just like in the Yup’ik example, he was describing visio-spatial IQ. White parents emphasize cognitive skills more because they are wired to do so, on average.

6. Students learn mathematics if taught in a culturally relevant way.

He says when Alaskan Yup’ik kids were taught geometry using fish racks, they outperformed students who were taught the same concepts conventionally. This, again, back to visio-spatial ability. They are able to imagine their surroundings and remember where they were, giving them an advantage.

7. It is possible to assess in the US in ways that increase prediction and reduce multicultural differences.

He showed 2 different creative writing essays. He showed differing examples of creative writing and verbal ability. He says that in terms of predicting first-year GPA, with adding the of creative and practical, they doubled prediction of performance.

He then shows the amount of each measure that is predicted by racial/ethnic differences. He says Asians do better on the math section, whites do better on the verbal, all of which is known and is caused by differences in visio-spatial and verbal intelligence between the races.

On the analytical tests, blacks, ‘Latino’ and American Indian groups didn’t do as well, but the Native American groups did better on oral storytelling, which makes sense due to their culture and how they evolved.

8. How schooling got to where it is.

He uses some crazy example. Saying that if you only allow students by height into college, that if you do a study 30 years later, with the model of Hernnstein and Murray, you will find that height is correlated with IQ (it is). But that’s a really bad example to use here.

All in all, Sternberg attempts to generalize abilities that fall in the factor and explain them away as something else entirely, not realizing that everything he is explaining is already explained by the general intelligence factor.

A few years ago when I first got in to race differences, someone I was talking to about this did say “well, based on cultural differences, intelligence is different depending on the context and situations you put it in”. So I thought it was funny that someone had a talk on it. Clearly, he’s wrong.

He’s attempting to say that in differing contexts, we’re all smart or dumb in some capacity or another. Which is true to a point, but the factor says otherwise.

You could also explain Sternberg’s theory as not looking at intelligence, but looking at personality differences and how they manifest and help the intelligence in that certain culture/society.

All of the examples he cited fall on the factor, not anything else.

Refuting Agabond on Scientific Racism

2500 words

To set myself apart from other HBD bloggers, I decided to start a few series, one on AfrocentrismHBD and Sports and refutations on how race isn’t a social construct. Agabond has a lot of untrue things to say, and I am here to refute them. Agabond, you can expect a lot of pingbacks from me on a lot of your posts, so get used to this.

Agabond wrote an article on the cons of Scientific Racism. The whole article is wrong.

According to race realism and the field of human biodiversity (HBD), the scientific racism of our day, the following are true:

  1. Race is genetic.
  2. Race affects intelligence.
  3. The races in order of intelligence are: Asians, Whites, Hispanics/Mixed, Blacks.

All of these are true.

Why this is wrong:

  1. Race is a social construct, created by the rules of society not by genetics.

My favorite saying from race-denialists. Yes, everything is a social construct. The Universe is a social construct, but that doesn’t mean that it doesn’t actually physically exist. We have social constructions for EVERYTHING, does that mean that NOTHING exists because they are social constructs?


The above picture is a PCA graph showing how the different races cluster on the graph. This is actually scientific evidence that what we call ‘race’ and ‘ethnicity’ has an actual biological basis. You say that “it’s created by the rules of society not genetics”, but you can clearly see here that GENETICS shows that humanity CLUSTERS into distinct groups.

2.  The differences between people from different parts of the world are too new and too slight to account for differences in IQ.

Not true at all. They are not “too new”, Agabond. Due to genetic isolation between populations for thousands of years, i.e., no population migrations between people with different genomes, this caused evolution to happen faster.

Faster evolution means more ethnic differences. This is due to, as I alluded to before, no migration of others with differing genes. Due to us moving genetically AWAY from each other and not genetically CLOSER from each other, shows that evolution is speeding up in the OPPOSITE WAY.

How are they too new and too slight to account for differences in IQ? Selection pressures varied depending on where those populations evolved. The more cognitively demanding Northern part of Europe, as well as the cognitively demanding parts of Asia that East Asians evolved in led to cooperation, which in turn led to evolutionary selection pressures, ala altruism. They also had to be smart with their food in regards to rationing. Along with more variables, over tens of thousands of years of genetic isolation, populations evolved to have distinct physical, as well as biological differences due to those certain selection pressures in those environments.

The less cognitively demanding parts of the world, along the equator, doesn’t foster high intellectual capabilities due to the lifestyle of the peoples there. They lived a mostly hunter-gatherer lifestyle (which was extremely difficult in Eurasia during the Ice Age). Evolution dictated the traits that it would enhance with Africans, e.g., longer limbs for better throwing and to cover more ground while running to get food, darker skin due to the climate, as well as their hair.

There are evolutionary reasons for everything. You should have done a bit more research here before writing this.

Your intelligence is determined not by your race but by where you were born, when you were born, a bit from your parents’s genes and the rest from what you make of it.

Yes, it is determined by your race, but I’ll get back to that later. Depending on where you’re born? Sure. If you’re born in a place with high rates of disease, parasitic load and bad nutrition, this will retard IQ. But for those born in first world countries, their IQ is at their genetic limit due to better nutrition. You said “where you were born”, do you even realize that “where you were born” means that you’re giving credence to the hereditarian hypothesis?

When you were born? Is this an epigenetic argument?

A bit from your parents genes, well more than a bit. Funny you say that. We know that the mother’s IQ is the best predictor of the child’s IQ. That being said, in studies of racially mixed black and white children, those with white mothers have higher IQs than those with black mothers. So yes, it is your parents genes. I assume you were going for the “individual variation in IQ is greater than between the races” is what you were going for. Not going to work.

The rest is what you make of it. I agree here. Even those with high IQs won’t be automatically successful, personality variables have a lot to do with it, which I will cover in a future post.

1. Correlation does not equal causation

Just because blacks in America have a higher crime rate or a lower average IQ does not necessarily mean the cause is mainly genetic. To come to such a conclusion you would have to assume that racism is pretty much dead, that American society is just so gosh-darn fair to everyone that genetics is pretty much all that remains to account for the differences.

I can’t count how many times I’ve heard this since I jumped into the black-white IQ debate. Yes, we know that correlation does not equal causation, but with retesting what you tested before with the same variables and lab conditions, if you come to the same conclusions, it is not a correlation does not equal causation argument.

Higher crime rates and lower average IQs are inversely related. There is a negative correlation there. We can see here that the low IQ being correlated with crime argument holds up in studies.

Deborah Denno analyzed data from 987 African American school children in Philadelphia. Her data contained multiple measures of intelligence collected at ages four, seven, and thirteen as well as officially recorded criminal offenses. Chronic, violent offenders consistently had low IQ scores. For example, female chronic offenders were almost four times less likely to be in the top third of verbal-IQ test scores than female nonoffenders. Similarly, male violent offenders scored 10 to 17 percentile points lower on measures of vocabulary, reading, and language than nonoffenders.

In addition to finding a robust IQ-crime correlation, studies have turned up two other empirical regularities worth noting. The first regards two different types of IQ measures: performance IQ (PIQ) versus verbal IQ (VIQ). Performance IQ is measured with nonverbal tests of attention to detail, manual design construction, and visual puzzle solving. Verbal IQ is measured with tests of general factual knowledge, abstract reasoning, mental arithmetic, and vocabulary. Studies have consistently found that criminals have PIQ scores close to the general population but VIQ scores substantially lower. This PIQ > VIQ finding holds even when controlling for race, class, and reading ability (Moffitt), suggesting that verbal intelligence is a more important correlate of criminal behavior than other types of intelligence.

I also touched on black crime and correlates for crime here. No matter what you can say about this, low IQ is correlated with crime. There are countless studies on this. Juvenile criminals average 92, whereas adult offenders are at IQ 85, right at the black average in America.

Genetics does account for the difference though you seem dishonest enough to believe any other reasons for it.

2. Confirmation bias

Scientific racists notice the cases that prove their ideas while overlooking those that disprove them. But in science it is the exceptions that disprove the rule. That is why the law of gravity is still a part of science: no known exceptions!

Care to tell me what they overlooked that disproved them? Why did you not use any examples?

3. Lack of expertise

Look at the race realists and HBDers you hear about most:

  • Steve Sailer, journalist/computer salesman.

His occupation says something about his knowledge on these subjects?

  • J. Philippe Rushton, psychologist.

OK? What about him? He’s a Ph.D. in psychology. He cites what he says, obviously. Rushton is one of the most important psychologists of this generation. Have you ever read any of his books, or have you only read attack articles on him? He first began researching the study of altruism. This gives him credibility, in your eyes, to talk about racial differences, as well as HBD. Hell, altruism is how our complex societies formed. That is a part of HBD as well, but you seem to talk about things you don’t know.

  • Francis Fukuyama, political economist.

First I’ve heard of him. Seems to get heat for his book arguing that we have almost reached the end of history. He says people have misunderstood his thesis, that “the French and American revolutions, and their underlying principles of liberty and equality, were the final resting point for human ideological evolution. So we need to consider whether Hegel, when he declared the end of history in 1806, was not right. My argument is concerned less with the world of real events and more with the world of ideas. Essentially the question I was trying to pose is whether there are any systematical ideological competitors left to modern liberalism.”

  • Steve Hsu, astrophysicist.

I love Steve Hsu. It seems that, according to Agabond, you can’t have other interests outside of your field, and if you do have interests outside of your field and speak on them, that no one should listen to you. Things don’t work like that. Steve Hsu is actively looking for intelligence genes. He also shows the reality of human genetic variation.

Just because someone is interested in things outside of their field, does that mean they can’t become an authority on it?

  • Richard Herrnstein, psychologist.

Same with Rushton. Are you telling me that psychologists can’t study IQ differences and behavioral differences between races? Hernnstein knows damn well what he’s talking about in terms of IQ. Are you trying to use Hernnstein and Murray as examples of people who talk about actual human genetics? Well, they don’t. They talk about IQ, and yea they talk about genetic causes for it, but they’re mostly concerned with the policy of the country that we are no noticing because we are ‘IQ blind’ so to speak.

  • Charles Murray, political scientist.

Same as above. Murray has defended himself multiple times with attacks him and Hernnstein got on The Bell Curve. 22 years later, and the book is still not refuted.

  • Arthur Jensen, psychology professor.

My personal favorite. He is THE AUTHORITY ON IQ as well as RACE DIFFERENCES IN IQ. Sure Rushton and Jensen bring up genetics sometimes, but they always cite where they got their information from.

Really bad arguments here.

You notice anything strange? No biologists or anthropologists, much less geneticists.

>some of the biggest names in HBD aren’t biologists, anthropologists (LOL), and geneticists

>means there are no HBD biologists, anthropologists (LOL) and geneticists

Nice fallacy.

Why in the world should we trust these people over biologists and anthropologists, the very people who study these things for a living? To leave no stone unturned, some biologists and anthropologists have even written books about race for the general public:

This is going to be good. Let’s see what “has been written for the general public by biologists and anthropologists”.

  • “Guns, Germs, and Steel”, Jared Diamond, biologist

!!!! People still cite this?!?!??!?!?

I’ll say something on G,G&S then let Rushton take over:

So different levels of civilizations can be traced to environmental differences and not innate differences in races? Because physical environment can explain civilization differences does that mean all human brains are the same on average? Horrible strawman. No one says environment doesn’t matter.

We can look at 2 countries within Sub-Saharan Africa. Look at South Africa. Still one of the wealthiest countries in Africa. Economic freedom isn’t the only source of wealth, human capital and natural resources are important. The lack of proper resources for civilizations in the past isn’t why Africa is poor today since we can see actual African countries that are better of by simply having more economic freedom.

The poverty today in Congo isn’t dated back to the dawn of time. Diamond says New Guineans are probably smarter than white Europeans. So does he accept that all races are the same in the brain except New Guineans? So does he then accept that human brains can differ in environments? Jared Diamond’s work is irrelevant and does nothing to explain why the various races perform differently in Europe. You can say racism or lingering effects of oppression, but the reasons for Africa’s poverty is not relevant to the racial gaps in Europe and America.

If you think it’s caused by environmental poverty in the past, you still have to argue the facts on racial differences today, the evidence still exists.

Jared Diamond is a man who spent a lot of time in Papua New Guinea. I guess he grew to like the natives there and befriended some of them so he makes ridiculous leaps in logic to actually say they may be more intelligent than Europeans. Hilarious. Any intelligent person can see the ridiculousness of what he claims. I can’t even begin to think how, when faced with all of this evidence of differences, that you can possibly believe in some warped view of equality or egalitarianism.

Here is Rushton’s dismantling of G,G&S.

  • “The Mismeasure of Man”, Stephen Jay Gould, biologist

Arthur Jensen refutation here.

JP Rushton refutes it here.

  • “Genes, Peoples, and Languages”, Luigi Luca Cavalli-Sforza, geneticist

What about it?

  • “Man’s Most Dangerous Myth: The Fallacy of Human Race”, Ashley Montagu, anthropologist

Never heard of this book but from the Amazon review:

It presented a revolutionary theory for its time; breaking the link between genetics and culture, it argued that race is largely a social construction and not constitutive of significant biological differences between people.


These books are good to help you overcome the racist brainwashing of American society.

Let’s see. G,G,&S is trash. It has some cool tidbits of information, but it’s largely not true and is an egalitarians way of attempting to say that Europeans “got lucky” in regards to geography.

Mismeasure of Man is full of sidestepping and not addressing points, as well as wishful thinking mixed with lying about the truth and not telling his audience certain things. Sure, if anything, this book will make you MORE BRAINWASHED.

No idea why you cited Cavalli-Sforza.

A book that says race doesn’t exist. Wow, that’s a new one.

4. Conspiracy theories

The reason scientific racists give for trusting, say, Steve Sailer, a computer salesman, over Cavalli-Sforza, a professor of human genetics who has, like, studied race, is, wait for it, that people like Cavalli-Sforza secretly agree with them but are too afraid to say so in public! Have they gone mad?

What are you talking about? Are you talking about how Cvalli-Sforza uses terms like “population clusters”? That doesn’t matter. You can call the things what you’d like, but that doesn’t change the underlying biological reality of genetics, race and ethnicity.

If you’d have understood Cvalli-Sforza, you’d get that.

I know you got this pingback, Agabond. I’d love a response from you though I doubt it.


Blacks in Medieval Europe? Afrocentric Ramblings

1000 words

Came across this article today from a (totally not unbiased source) person who seems to believe in the myths of Afrocentrism.

I’m always amazed at how many people are so quick to argue that people of color did not exist in Europe during medieval times or that black people, for instance, weren’t around during the Greek and Roman eras. And to include said PoCs during such time periods would be unrealistic and another example of shoving a PC agenda down our throats OH-EM-GEE.

Not that it would be unrealistic, just that those ‘PoC’ get thrown into positions of power in the setting they’re portrayed in, which is not realistic at all. Sure the Romans had black slaves, but that doesn’t mean that any important Senators or Emperors were Negros. Just because they were “around” doesn’t mean they did anything of significance, or even had a large population in comparison to Romans and Greeks.

This usually comes up in medieval fantasy stories. Like say for instance, Guinevere in BBC’s Merlin. Actress Angel Coulby caught heat for daring to be a beautiful powerful black queen.

His last 4 words aside (Kanazawa’s studies say otherwise), what kind of ‘black queen’ was there ever in Europe? Name one, please. Of COURSE she’s catching heat, as that’s not historically accurate, and I’m sure that most people care about being historically accurate in some of the things they watch. I know the show is a ‘fantasy’, but I don’t even think some people could suspend their disbelief to believe that there were ‘black kings and queens’ in medieval Europe.

This nonsense makes me laugh A LOT for two main reasons:

1.) It’s a huge double standard in that whites can always be placed in stories revolving around Egypt, China, Africa, or pre “discovered” America and no one blinks an eye.

Well, think about this. The majority of the country that these movies are made in and mostly come out in are white. Egyptians were Caucasoids, so using whites isn’t too far of a stretch. What about Africa and China and ‘pre-discovered America’? Care to give some examples?

Yet if a PoC shows up in medieval fantasy tale, it’s unrealistic. Talking animals, elves, dragons, gnomes, all totally plausible. Black people in Europe? Too many people can’t suspend disbelief at that.

Some things are just that unrealistic that you cannot suspend your disbelief of them to watch a story. =^)

First of all, people of color have been in Europe for ages. Think about it. Between all the wars, travel, and trade that countries and nations do, it would only make sense that some PoCs have traveled, relocated, and settled in other lands.

OK? Populations migrate all the time, this means nothing. Does that mean they had a strong historical presence? No way.

The Egyptians who dealt with the Romans and Greeks were black. Egypt is in Africa, in case you didn’t know.

No, they were not black. They were West Asian Caucasoids. Genetic testing on mummies from the years 806 BC to 124 AD shows that they have the haplotype I2, which originated in Western Asia. Makes sense, seeing as Egypt is right by the Middle East, and Egypt and Sumeria did have extensive trading with each other. Just because “Egypt is in Africa” doesn’t mean that they were black. The whole of North Africa are Caucasoids.

Rome and Carthage went to war and Hannibal gave the Romans a run for their money. Which anytime you can give the ROMANS a fight, you’re a bona fide badass.

I definitely agree that if you can give Rome a fight, you are a bad ass. But there’s one problem: Carthage was a Phoenician civilization, not sub-Saharan African. The “picture” you use of Hannibal is NOT an accurate portrayal of what he actually looked like.


He looks pretty damn Caucasoid to me. This fantasy of Afrocenstrists to insert themselves into most any important event in world history just to say they did something worth talking about truly shows the inferiority complex of blacks.

Also, to see what Phoenicians really looked like, look to Sardinians. Due to genetic isolation from being on the island, they have hardly any admixture from outside the island. They also speak a Phoenician language.

If you’re a Greek Mythology buff like myself, look up a brother named Memnon. Speaking of Greek Mythology, look up Andromeda, Perseus’ wife and see where she’s from. Here’s a hint. And by hint I mean answer: Ethiopia.

Are we to take all peoples of antiquities word for everything they say? Are we made of corn? Is the story of Romulus and Remus true? Were there gods on Mount Olympus?

Again. Just because they were present, doesn’t mean they had ANYTHING to do with any discoveries of that time period.

Blacks actually ruled in some parts of Europe and could be found in Scotland as early as the 10th century. Funny how that isn’t taught in school.

Funny how you provide no source.

Still not convinced? Look up Othello.

Why should I look it up? Oh, it’s because it’s another thing co-opted to add blacks where it was originally a play involving whites.

Is this guy being cast in this play almost 200 years ago supposed to mean anything?

Amina of Zaria was in fact the inspiration behind Xena: Warrior Princess.

Amina of Zaria is a myth.

Alexandre Dumas, the author of The Three Musketeers and The Count of Monte Crisco? Black excellence also.

Meaning… what exactly? This is pretty meaningless. OK, cool. Some blacks can write good stories, but they are outliers. The Bell Curve, etc.

And our accomplishments didn’t stop there. As this amazing heroine’s story illustrates.

Who the hell is ‘Belle’? Also, it says it’s BASED on the ‘inspiring’ true story. Meaning, things are embellished to make a better story. Or did you not know that?

So if you’re one of those who constantly gripe about the presence of PoCs in period fantasy as being unrealistic; your history, do learn you some.

No, you learn you some. You’re spreading ridiculous things to people who know no better. Just because ‘PoC’ had a presence in these places doesn’t mean they did anything of note.

I hope you respond to this refutation of your garbage, Nerd of Color.

Towards a Theory of Everyone: Chanda Chisala Rebuttal on the Nature of the Black-White IQ Gap

3700 words

Chanda Chisala has been writing a series of articles for the Unz Review for almost a year now. They are on the nature of the black-white IQ gap. I’ve been eagerly awaiting his theory on the cause of the gap, as I always welcome any and all new information concerning this. Well, I was pretty underwhelmed by his theory.

Sowell has always used two arguments to cast doubt on the genetic hypothesis: the first one is the Flynn Effect or prior versions of it that he had noted himself, which shows that IQs have been rising with time for blacks and other people all over the world.

The “Flynn Effect” is rubbish. PumpkinPerson says:

It turned out Rushton was one of those “The Flynn effect is irrelevant” people. He found it prima facie absurd that we could have been a nation of mentally disabled people a century ago. It simply didn’t make any sense to him, given the outstanding achievements of early 20th century society. But it didn’t make any sense to me why the same tests that were culture reduced enough to measure the intelligence of South Africans could be so wrong when measuring Victorian intelligence. I needed an explanation. The Flynn effect is unrelated to g (general intelligence) and that was enough for him to just dismiss it and move on.

So even though Rushton and Jensen rebutted Flynn, as well as Flynn and Dickens, Chisala still chooses to use the Flynn Effect argument. Here is why it is irrelevant:

Let’s say Flynn is right. The average black now is as intelligent as the average white in 1945. That’s supposed to show that the race difference in IQ is environmentally caused because there hasn’t been that much genetic change in the white population and the IQ has allegedly gone up 15 points. So, you can have a 15 point difference created by just an environmental change, no one knows why. Some think better nutrition or malnourished brain, etc. That’s also a fallacy. Just because a change in one group over time is due to an environmental change, doesn’t mean, or even make it probable, that a difference between 2 groups at the same time is due to an environmental change. The Flynn Effect make’s that highly unlikely and here’s why.

The Flynn Effect, assuming it’s real, has been acting completely uniformly in every population. Any country you ask, the rate of increase is 3 per decade. That means it’s an environmental factor that affects whites and blacks the same way as well as the whole world. And as a result of this uniform environmental factor, you have a difference in IQ that’s being preserved. That would suggest that the response on the parts of blacks and whites is due to some non-environment factors, a genetic factor, which is making the difference in IQ remain constant as the Flynn Effect goes into effect.

What makes it even more unlikely, in the last 60 years, their environments have become very similar since segregation. These differences don’t exist now, they go to the same schools by court order, same TV shows, same movies, basically same environment for both, and yet, that increasing similarity in the environment, the Flynn Effect, the IQ gap has remained intact. Which means whatever counts for the gap is genetic and not environmental. The more and more similar the environment, the less and less of the difference can be due to the environment and the more and more it must be due to genes. So this 15 point gap surviving these changes in the environment, seems more and more likely to be genetic in origin.

So because this ‘Effect’ is the same across all populations and the gap didn’t close, that means it’s genetic. If the gap persisted even when IQs were rising 3 points per year, the B-W gap has still persisted, proving that it’s genetic.

That is why the Flynn Effect is irrelevant. This “Effect”, has been a slight upward trend in IQ, around 3 points per decade, which, in my opinion, has to do with the advent of better nutrition and an industrialized society. The rise in IQ started around 1880, almost perfectly coinciding with the industrial revolution in America. Along with a more industrialized society, it’s possible to give most citizens in the country good enough nutrition to where they are not iodine deficient (adding iodine to our salt boosted Americans IQs), as well as being deficient in zinc, iron, protein and certain B vitamins which the effects of not getting enough leads to the brain not growing to its full potential, which in turn leads to a lower IQ.

One more point on the Flynn Effect. The Flynn Effect does not occur on g, as it is not a Jensen Effect. Rushton defines Jensen Effect as follows:

Significant correlations occurring between g-factor loadings and other variables have been dubbed “The Jensen eff€ect”.

Thus the secular increase in test scores (the “Lynn±Flynn e€ffect”) is not a “Jensen e€ffect” nor is this the first time the discriminating power of the Jensen eff€ect has been shown.

The Flynn Effect is not on actual g. The black-white IQ gap is most heritable on those sub-tests that correlate highly with g. Through correlations on scores on inbreeding depression, Rushton and Jensen (2005) conclude that the magnitude of the black-white IQ gap is 80 percent genetic and 20 percent environmental.

Now to get to this other part of his theory.

The second very unique and original argument he has used is the differential IQ performance of black males and females, which seems to favor the females. He charges that the genetic hypothesis can not explain this, but it is explainable under an environmental hypothesis.

Sowell’s second argument is much stronger than the Flynn Effect argument because it is very difficult for hereditarians to explain why there should be a gender difference in African American IQ, especially one favoring females (let’s call this the “Sowell Effect,” to avoid repetition). This is very problematic for hereditarians, particularly since the trend is normally for male IQ to exceed female IQ, especially at the higher levels of the IQ distribution curve. We can see this unique trend among blacks even in the applications to medical school, a field that is considered a good metric for group intellectual comparisons.

This is very simply explained. Occam’s Razor anyone?

Even today in Africa, the women did the hunting and gathering, giving them more selective power. The same holds true for Eurasian men, who have a slight advantage in IQ over Eurasian women. Because of the colder climate in Eurasia, meat was one of the staples they had. So that shifted selection pressure from women over to men. Since men had the food, and the ability to hunt for it for that matter, men had more selection power to select the best possible mates. This led to Eurasian women being selected for beauty, whereas this led to African men being selected for physical attractiveness.

To quote from Erectus Walks Amongst Us:

In Africa, the women, even today, farm and gather food, so they have more selection power, but in the colder climates more of the food was meat, especially in the winter, and hunting was done by men, shifting some selection power to men. (Miller, 1994a). As a result of selection by men, Eurasian women have become more beautiful and, as a result of selection by women, Eurasian men have become workaholics and slightly more intelligent than Eurasian women (more intelligence = a better provider in Eurasia). African women have become slightly more intelligent than African men, however, who have become the more physically attractive sex.

So more intelligence led to a better provider. Being able to farm for and or hunt for food gave those who did it the selection ability to be able to sexually select to their liking.

Sowell (2013) claims this empirical victory in Intellectuals and Race (page 79):

Further evidence that the male-female difference in IQs among blacks is cultural is that black orphans raised by white families show no such female superiority in IQs, in addition to both sexes having higher average IQs than other black children.

Chisala says the Sandra Scarr data from the Minnesota Study does not back up this claim.

There are other studies that could possibly back Sowell up if he is right and we should check those too. For example, there is the well-known Eyferth Study in Germany which monitored the IQs of illegitimate children of black and white American soldiers who were stationed there at the end of the Second World War.

The Eyferth Study is a joke.

Wikipedia got its data from The g Factor, a book by Arthur Jensen (1998) that is probably the most cited in the racial intelligence debate. I went to the cited page and indeed found that Wikipedia had correctly reported Jensen’s data. The Sowell Effect had apparently disappeared among the black children born in Germany and the strong culture hypothesis seemed to be vindicated.

Arthur Jensen explains the cause for the mixed race children (and at the same time the cause for black female children having a higher IQ) on pp 483 of The g Factor: The Science of Mental Ability:

Finally, heterosis (the outbreeding effect; see Chapter 7, p. 196) probably enhanced the IQ level of the interracial children, thereby diminishing the IQ difference between the interracial children and the white children born to German women. A heterotic effect equivalent to about + 4 IQ points was reported for European-Asian interracial offspring in Hawaii.

This means that we can also resolve the debate about whether the black soldiers in this experiment were more selected than the white soldiers. It appears that the hereditarians were probably right on this point: the black soldiers had to have been significantly more intelligent than the white soldiers because the presence of a Sowell Effect indicates that the IQ of the black children has received extra depression (through an abnormal lowering of the male IQ, as usual.) However, it’s another Pyrrhic victory for hereditarians: the continued existence of apparent extra depression for black male IQ makes their simple models impotent, just as it does for standard environmentalist models.

Yet another point that Rushton and Jensen shoot down in their magnum opus paper:

Second, 20% to 25% of the “Black” fathers were not African Americans but French North Africans (i.e., largely Caucasian or “Whites” as we have defined the terms here). Third, there was rigorous selection based on IQ score in the U.S. Army at the time, with a rejection rate for Blacks on the preinduction Army General Classification Test of about 30%, compared with 3% for Whites (see Davenport, 1946, Tables I and III).

Huge error. About one-quarter of the ‘black fathers’ were French North Africans! Because North Africans have a higher genetic potential for IQ (nowhere near that of SSA), this is not a true representation of black fathers and white mothers.

Thus, racial hereditarians can not explain why the race of the mother matters

Is he being serious right now? It’s easily explained. We know that the mother’s IQ is the most important predictor of the child’s IQ. The prenatal environment is better in the white mother than in the black mother. Due to the mother’s IQ being the most important predictor of a child’s IQ, doesn’t that end the black-white IQ debate right there? Due to the fact that mixed race black and white children with white mothers show higher IQs than those with a black mother and white father, doesn’t that end the black-white IQ debate?

We racial hereditarians can definitely explain why the race of the mother matters. You should have done a bit more research into this matter.

And now on to my favorite part of this article. It’s so out there in its propensity for being a possibility for the cause of this gap between the races.

In Black Rednecks and White Liberals, Sowell (2006) theorizes that the modern ghetto culture of black Americans came from their association with white rednecks during the time of slavery and he believes it is the preservation of this detrimental culture – preserved with the intellectual help of “white liberals” – that keeps the black IQ low due to its anti-educational, anti-intellectual disposition. Sowell convincingly demonstrates some very uncanny similarities between ghetto black culture today and some aspects of white redneck culture that was more dominant in the South in the past than it is today, as more and more whites have decided to abandon it.

One huge problem with this. If that’s the case, if the cause of lower intellectual achievement is due to black Americans association with white rednecks during the time of slavery, all we need to do is look at Africa to see how they did without the “association with white rednecks during the time of slavery”! We can also look at those countries never touched by colonialism to see that they’re the same backwards countries.

Of course there will be “uncanny similarities”. When you have two groups who have lived amongst each other for a certain period of time, traits of both groups will rub off on each other. This is not a genetic cause, but an environmental cause. The similarities come down to being around other groups.

And here it is, here is the kicker:

Although I agree that the case for a cultural transfer from some groups of Southern whites is very strong, I think it is more likely that this “culture” was actually passed to blacks genetically rather than through mere influence and imitation. If that is the case, then it was in fact the presence of relatively strong mutations in that sub-population of whites that was affecting the stranger aspects of their behavior and intelligence, and they passed on the same genetic condition to blacks through mating with the black women.

THIS is his big reveal? No. Way. This has to be one of the funniest things I’ve heard in the black-white IQ debate. Hey, Chanda, there is something called Regression to the Mean (nice post, Jayman), which throws your theory out of the water.

blacks in fact had more stable families and even had less out-of-wedlock children than whites. He uses this to show that if slavery was the root of these problems, they could have started much earlier.


In this paper by Steven Ruggles, he says that analysis confirms that the high incidence of black Americans of single parenthood and children residing without their parents is not a recent phenomenon. Data shows that from 1880 through 1960, black children were two to three times more likely to reside without one or both children than white parents. This directly goes in the face of what liberals say is the cause of the demise of the black family structure. Ever since blacks have been free from slavery has this begun to happen.

What explains this perfectly, is Rushton’s r-K Selection Theory (now known as Life History Theory). Those who are more r selected (Africans), will have more children but spend less energy caring for them. Conversely on the other side, those more K-selected (Orientals and whites in the middle of K and r), will have fewer children but show more attention to them.

Some of Sowell’s strongest critics on this theory also suffer from the same progressional problem. Scholar and investigative journalist, Steve Sailer, for example,argued that much of the negative behavioral tendencies in black ghetto culture must have come with them from Africa. His theory is also unlikely to be true if the statistics about marriage and out-of-wedlock births etc are true. If their culture came with them from Africa they would not have had a long period where that culture seems to have been almost absent only to forcefully show up much later, in generations that had the least connection to or memory of Africa.

Sailer is correct. See my above cite showing that from 1880 through 1960 black children were two to three times more likely to reside with one or both children than white parents.

So we can see that it’s not a recent phenomenon.

Our theory thus explains a paradox that is difficult to explain by present environmental or hereditarian models: when blacks from Africa, the Caribbean and the US are compared, it is the least white-admixed black group that apparently performs best (the Africans), followed by Caribbean blacks who are in between; the most white-admixed group, the native black Americans, do worst. And yet within these communities, it is not necessarily true that the more white-admixed individuals perform worse; they may actually be over-represented on the highest levels of academic or social performance.

Dr. James Thompson says the sample for the Caribbean blacks in the UK is not a representative sample. Also, the hereditarian theory does not say that ALL Africans and African-descended peoples have a lower average IQ. It’s perfectly within the hereditarian hypothesis to have some African countries, as well as peoples, descended from African countries around the world, show a genetically higher IQ.

The evidence of such deleterious mutations still existing among modern day poor whites can be seen, not just from their low intellectual performance (going even lower than poor Caribbean boys), but even from their violent reactions against their fellow well-performing students, a culture that is also seen among ghetto black Americans, which is further evidence of a mutational rather than an imitational cause.

Wow, you mean to tell me that American whites aren’t a monolith and that there are some white groups in America with a lower average IQ? News to me!!

This solves one of the stronger challenges raised against the Unzian Asian Exception conjecture, asking why it was not East Asians who produced the greatest epochs of human intellectual achievements in history if it is true that their average IQs have consistently been stubbornly high for most of modern human history. It would be because the same canalization that protected them from low intelligence also “protected” them from producing the numbers of super-creative intellects that would be required for such revolutionary achievements in a concentrated period of time. They have a small creative smart fraction, in short.

The cause for lack of East Asian creativity is due to conforming in East Asian societies, which Rushton says in Race, Evolution and Behavior that it’s a genetic trait. Rushton did say that a larger average brain size means more creativity and that with social restrictions lifted, that East Asians may possibly become more creative than whites.

From time to time Lynn notes anomalies in his theory that require explanations. One of these is that Europeans made most of the great intellectual discoveries, while the East Asians, despite having a higher IQ, made relatively few—a paradox extensively documented by Charles Murray in his 2003 book, Human Accomplishment. Lynn proposes an explanation for this: it may be that East Asians are more conformist than Europeans and this inhibits creative achievement. (In Race, Evolution, and Behavior, I presented evidence that this personality trait has genetic roots.)

And yet the same hereditarians admit the conspicuous paucity of highly significant originators and innovators among East Asians, despite showing over-representation in high intellectual aptitude, sometimes very precociously so. East Asian women, who have the highest canalization coming from gender and race, are the most exemplary of this contrast. The shortage of such super-creative phenotypes can not be because they lack the numbers of people with the right genotype, but because the genotype is “buffered” from phenotypic expression by canalization.

See above.

Ashkenazi Jews, on the other hand, may be the most over-represented at the top of creative achievements in different intellectual fields (from chess to physics to literature, etc) simply because they happen to also be quite lowly canalized.

No. No way. Ashkenazi Jews are over-represented at the top of creative achievements in different intellectual fields because they mated with Roman women thousands of years ago. I have already noted about the mother being the best predictor of child’s intelligence. That’s the cause for high Ashkenazi IQ, not canalization.

Lower canalization also means that their improvement will be more rapid when such environmental conditions positively change (as can also be seen among recent black African immigrants, whose radical improvements begin even in children who were born under bad conditions in Africa, thus defying all kinds of hereditarian limitations.)

This is a case of super-selection. Only the most intelligent peoples leaving the country to immigrate.

In short, there is basically false assortative mating among black elites on average. This also explains why the mixed black male children have lower IQ when their mother is black than when their mother is white, as we demonstrated above.

I went over this earlier. Black mothers have a worse prenatal environment than do white mothers.

This obviously would not mean that the usual theories of environmentalists are correct either, since it should also not make a difference to them if the boys are included or excluded from the black American samples, especially in elite families. However, as we have faithfully acknowledged, both environmentalists and hereditarians also have some empirically confirmed arguments. Our present hypothesis, taking account of differential gender and racial canalization in human populations, can hopefully help to unify the valid aspects of the environmental and hereditarian frameworks.

I’ve noticed that Chisala used a hybrid environmentalist-hereditarian position to explain his theory on the black-white IQ gap.

I refuted the “Flynn Effect”, as well as the part of the Eyferth Study that talks about higher black female IQ, refuted the section about Caribbean blacks in the UK, and finally, I refuted his claim that we hereditarians “have no explanation for a mother’s IQ being the best predictor of the child’s IQ”.

In conclusion, this is just an extremely long-winded way of saying “whites are the cause of low black achievement, crime, IQ and anything else negative that affects blacks in Western countries”.

If that’s the case, Mr. Chisala, why is Africa so backwards?
