touched on black crime a bit a few months ago. I will now go more in depth on reasons for black crime.

First, what is the caused of all crime, no matter the race?

People have always said that parental socialization was the cause of black crime. But, genetic confounding was never considered in those studies. Kevin Beaver et al found in an analysis of adoptees that once genetic confounds were properly controlled, the effects of parenting on criminal justice measures were nonsignificant. That’s weird. I thought parental socialization was the cause of a kid turning out bad or good.

What is the cause of rape?

In a 37 year nationwide study in Sweden, it was found that sex offending runs in families. They reported strong evidence of familial clustering of sex offenses, mostly accounted for by genes and NOT shared environmental influences (ie, the same thing happening to both people in the family, therefore being the environmental cause of rape).

It’s of course genetics. We know that there is huge variation between individuals of the same race/ethnicity, how about between races? It also follows Rushton’s Rule of Three, Asians on top, whites intermediate and blacks on the bottom.

There are testosterone differences between blacks and whites. On top of those testosterone differences, men who stay and raise children have, on average, lower testosterone. This was noted in the West, but non-Western samples gave differing numbers.  The study was conducted in two East African populations from Tanzania, Hadza foragers and Datoga pastoralists. They predicted that high levels of paternal care by the Hadza fathers would be associated with lower testosterone and that no difference would be found in non-fathers and fathers of Datoga men, who provide direct paternal care. The measurements in both populations confirmed the hypothesis, as well as adding further support that decreased testosterone leads to more paternal care.

What does that have to do with crime? Not having a father is detrimental to a young child, studies have shown in the UK that those from broken homes are more likely to commit crime than those from stable families. Also, seven out of ten offenders come from broken homes.

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.

Why did black father rates jump so much after the Civil Rights Movement?

I have my own theories.

Today, the black single mother rate is at 72 percent. In 1965, 24 percent of black infants were born without a father. What is the cause for that?

Blacks weren’t allowed to marry whites, and the CRA changed that. So with them being legally allowed to court white women, they obviously shied away from attempting to court black women. We can see that the trends show huge changes in 50 years. The cause is desegregation obviously, but what exactly is that environmental cause? Being able to court white women.

So with those men who DO stay around to raise children who show a decrease in testosterone, it’s extremely safe to say that those men who leave, regardless of race, have higher testosterone than those men who stay. This is reflected in racial single parent stats that show, again as for many more variables, Rushton’s Rule of Three.

What is wrong with black women? How come when segregation got lifted, black single motherhood rose exponentially?

Satoshi Kanazawa knows why. He noted in this study on why black women are not as attractive as other races, that women, on average are more physically attractive than men. EXCEPT BLACK WOMEN. The data shows black women as not being statistically different from the average, and far less attractive than whites, Asians and Native American women.

The cause is higher testosterone. Kanazawa says that the cause for this is due to the mean BMI of black women being 28.5 among black women and 26.1 among non-black women. Though he says that’s not the reason why black women are less physically attractive. Black women have lower levels of intellect net of BMI. Even the racial differences in intelligence don’t account for these differences. Black women are STILL less physically attractive, net of BMI and intelligence. Kanazawa says: “Net of intelligence, black men are significantly more physically attractive than nonblack men.”

Why is that? He says the reason is testosterone. He ends up concluding that testosterone differences are the only cause for these differences. With blacks having the highest testosterone out of all the races, black women obviously have higher rates of testosterone than white women. Those women with higher levels of testosterone have more masculine features, therefore making them less attractive.

Previous research has suggested that perceived attractiveness and personality are affected by the race such that White faces are more attractive but less masculine than Black faces. Such studies, however, have been based on very small stimulus sets. The current study investigated perceived attractiveness and personality for 600 Black, White and mixed-race faces. Many of the investigated personality traits were correlated with race when rated by White participants. Attractiveness specifically was greater for Black male faces than White male faces and among mixed-race faces. Blackness correlated with increased attractiveness. A reverse pattern was found for female faces with Whiteness being associated with attractiveness. The results are discussed in terms of the sexual dimorphism demonstrated in skin color. (Lewis 2010)

That’s the same as was noted in the Kanazawa paper. Darker-skinned males were more attractive, lighter-skinned women were more attractive.

Rushton wrote, in his last paper before his death, that skin color as a multi-generational adaptation to differences in climate over the past 70,000 years. He proposed life history theory (formerly known as r K selection theory) to explain the covariation found between human and non-human pigmentation and variables such as birth rate, infant mortality, longevity, the rate of HIV/AIDs and violent crime.

Dark skin is correlated with these things because of evolution.

High testosterone is linked to crimes of violence and sex. Men who gave saliva samples in prison were shown to violate more rules in prison, especially rules involving overt confrontation. Dabbs et al say: “the variety of rule violations suggests the behavior of high testosterone individuals reflects intractability, unmanageability, and lack of docility as well as aggression and violence.” Higher testosterone levels were associated with more violent crimes, parole board decisions against release, and more prison rule violations. This same thing was noticed in women, high-testosterone women had more crimes of unprovoked violence, increased number of prior charges, and decisions against parole.

For chronic adult offenders, the average IQ is 85, 1 SD below the mean of 100. Why do criminals have low IQ? Lack of abstract thought for one. Those with low IQ have a lack of ability to think of what their actions will do. Along with the lack of ability to delay gratification, paired with high testosterone and low IQ, that is the cause for higher than average crime in the black community in America.

Men with lower intelligence may be more likely to resort to evolutionarily familiar means of competition for resources and mating opportunities, and not to fully comprehend the consequences of their criminal behavior.

Even just a few points of IQ matter to criminality. There is a lot of data on the link between crime and low IQ. Who just so happens to have the lowest IQ in America on average?

It was noted in this study that states with lower IQs have more property crime and violent crime.

The sons of fathers with criminal records tend to have lower IQs than sons of fathers with no criminal history.

High testosterone lowers IQ.

Increased intelligence is also linked to lower sex drive. I would reason that as shown above, those with higher IQs will be able to resist natural urges better than those with lower IQs. This shows in NLSY data with lower IQ people having more kids, higher IQ people fewer kids.

All of this data piles up, and the only thing that jumps out, is that lower IQ people have more testosterone, lower IQ people commit more crimes, therefore, high testosterone and low IQ is the cause of black criminality.

The racial disparity was completely accounted for after including co-variates for self-reported lifetime violence and IQ.

    the link addressing high testosterone and lower IQ says nothing of either one. please check it. BTW- I was under the impression that high testosterone actually correlates w/ higher IQ.


    • RaceRealist says:

      Thank you for bringing that to my attention.

      I was under the impression that high testosterone actually correlates w/ higher IQ.

      There is evidence for the oppositie. High IQ correlates with lower testosterone, and therefore lower sex drive. Those with lower IQs can’t control themselves as well as those with higher IQs and therefore have more sex (as well as rape more) than those with higher IQs.

      High Testosterone Linked to Lowered IQ

      Testosterone is also correlated with IQ due to the fact that Africans have higher testosterone than Europeans, which Africans evovled near the equator.

      Most people don’t know this, but vitamin D isn’t really a vitamin; it’s a steroid hormone

      Higher levels of testosterone occur due to increased exposure to the sun. Of course, the Middle East gets more sunlight than does Europe, so their levels of testosterone will be higher due to increased vitamin D, which in turn increases testosterone, causing more acts of aggression. Vitamin D supplementation could possibly (we know it does) raise testosterone levels. Of course this is the case, seeing as vitamin D comes from the sun, and the more sun you get, the more Vitamin D you get, which increases testosterone levels.

      Those violent acts committed by those with high testosterone is also highly correlated with low IQ as well. There is a relationship with testosterone and low IQ as well as ability to control your impiulses, which those factors influence ability to control impulses immensely.


    • RaceRealist says:

      If that were the case, blacks would have higher intelligence than whites, but this is not so. Blacks are exposed to more testosterone in the womb, which is one reason they have higher rates of prostate cancer

      Black women had 50 percent more testosterone in pregnancy than white women, showing that blacks are exposed to higher levels of testosterone in vitro, which manifests itself in the prostate cancer rate.

      As I stated in my previous reply, vitamin D is a steroid hormone. Blacks evolved with more sunlight, so they clearly have more testosterone. Since sunlight is correlated with higher levels of testosterone, if the claim for higher testosterone being correlated with higher intelligence to be true, high testosterone ethnicities, such as American blacks and Mexicans would be more intelligent than whites. However, this is not true.
