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.

  3. […] On that same note, they may say that the judges and courts are biased against them as well. That once they see a black man in the court room, the always throw the book at him. Well, there is no evidence of discrimination in criminal justice processing. The racial disparity was completely accounted for after including co-variates for self-reported lifetime violence and IQ. Meaning, those with lower IQs are more likely to be criminals, which I have touched on here. […]

  5. brookingstyler says:

    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.


    • Ricks77 says:

      Great post – High Test and Low = Aggression and Crime / High IQ and Higher Testosterone normally means more creativity/innovation.

      However what is the impact of the following scenarios:

      High IQ/Low Testosterone = Outcome ??
      Low IQ and Low Testosterone = Outcome ??



    • 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.


    • Ricks77 says:

      @RACE REALIST – I understand blacks and their High Aggression/Low IQ and their Dark Skin and the Vitamin D is a steroid issue
      However please can can you explain Indians especially South Indians who are very dark, but on average have Low IQ and Low testosterone (why is this). Is it Indians (South Indians in Particular) are Australoid and not Negroid? How about Arabs.

      I think the General rule =

      Tropical Zone = Low IQ and Higher Aggression/Gratification.
      Cold Climate/Ice Climate = High IQ and Lower Aggression/Delayed Gratification.

      Please let me know your thoughts on Dark Skinned Arabs/Indians and South-East Asians all of which have Low IQ (between 80 and 90) but also do not appear to be too aggressive (maybe Arab and Muslims) thats likely due to Inbreeding!

  7. Chinedu says:

    The evidence simply doesn’t support the notion that blacks are more criminally inclined than whites. Whites have literally wiped out entire continents, including Europe itself. With regard to street level crimes, that tracks with socio-econmics, not race. When poor whites have been in urbanized environments their street crimes have been off the charts.


    • RaceRealist says:

      Eh, I’m kinda iffy on this now too, due to what I’ve recently read.

      Effects of MAOA don’t hold for women and the alleles are only activated after child abuse and neglect at a young age (Cohen et al, 2006):

      Moreover, meta-analysis demonstrated that across studies, the association between maltreatment and mental health problems is significantly stronger in the group of males with the genotype conferring low vs high MAOA activity. These findings provide the strongest evidence to date suggesting that the MAOA gene influences vulnerability to environmental stress, and that this biological process can be initiated early in life.

      And the effect only holds for whites, non-whites aren’t affected (Spatz and Brzustowicz, 2006).

      When it comes to MAOA, the mutation is extremely rare but when it’s there, pretty devestating things can occur as seen in the longitudinal study on Swedish families. East Asians are more likely to have the low-expressing allele of MAOA—which is linked to crime and aggression—however, clearly, East Asians have lower rates of violence than Europeans, Africans, or the Maori (Way and Lieberman, 2010).

      Further, I also no longer believe the ‘higher testosterone in blacks’ meme. It’s only found in blacks with lower SES, and it can be explained by environmental factors as stressful/violent situations raises testosterone (permanently).

      This is just talking about genetic components that have been associated with crime.

      If you’re interested, this book has me thinking a bit (the IQ part is garbage in my opinion—but some neat tidbits such as 3 SNPs being responsible for .3 IQ points—negligible to explain any ethnic differences in IQ—but the part on criminality is solid):

    • iffen says:

      I haven’t seen any evidence that blacks are ceteris paribus more criminally inclined. I would be quite surprised if this were true of any group since we all evolved in groups and all groups enforce rules and punish or rid themselves of the rule breakers. It is quite clear that historic, economic and cultural differences (including modern dogmas which tend to not hold blacks as accountable for their behavior) are at the root of the disparate level of criminal activity by blacks in the US.


    • ilovehitler says:

      what are homicide rates in africa country by country? are the statistics reliable? there’s currently a slow motion genocide of white farmers in ZA. central america has the highest homicide rates. is it genes? or is it drugs? are black canadians and british and french more likely to be criminals when compared to equally disadvantaged whites?


    • RaceRealist says:


      what are homicide rates in africa country by country?

      I know of a paper on South Africa:

      Murder in South Africa: a comparison of past and present, first edition, pg. 10

      This equates to 309,583 murders from the year 1950 to 1993 (44 years – averaging 7,036 per year), meanwhile according to SAPS statistics, 193,649 murders were committed in 8 years after the “new democratic dispensation” came to power, thus giving an average of 24,206 per year (crime statistics for 2002/03 are not yet available). However if we consider the Interpol statistics, which are only available on their website for the years, 1995-1999 and 2001 (6 years), the number of persons murdered in South Africa within those 6 years is 287,292 – averaging 47,882 per year. 2 Clearly the new government is not winning the war on crime, especially violent crime.

      These numbers seem astronomical to me. For comparison, there were 15,696 murders in America in 2015.

    Wqit can you delete this so I can change my name. I will post it again.


  9. Coordinate System says:

    I have been looking at twitter profiles of young, pretty, feminine white females and it seems that it is accepted by them to fill their pages with content involving black males and rappers with some posts saying upfront that they find them sexy. They also very much enjoy the brutish dialect that blacks have. Some of the profiles are more extreme in that they contain rude remarks about white males. Very degenerate society. What is your opinion?


    • Coordinate System says:

      I do think however that when white females date outside of their race they date ones who functionally act white and in more diverse settings they date their own kind.


    • RaceRealist says:

      People match on heritable traits, whether it be IQ, anthropmetric measures, etc. Opposites don’t attract, contrary to popular belief. Birds of a feather flock together.

      So more often than not, a low IQ ghetto black will match with low IQ ghetto white and you can tell by the behavior.

      It of course holds for the reverse as well. And intelligent black will more often than not end up with an intelligent white. Interracial marriage rates are low though.

  10. Silke Wagner says:

    The problem isn’t high testosterone levels in men, but the way in which they are primarily taught to deal with those high levels of testosterone. With our society of instant gratification, a college experience that has a system in place to make it not only socially acceptable, but desirable for males to act on their urges, a media system that makes women seek to exert their “sexual liberation” in as bad, or at times, more deplorable ways than same aged males, and no rites of passage of what a “man” is, most young males have known no other way than to be, and to paraphrase the pervading sense of what you are calling all young males, “Little Horn Dogs”. And even then, even if those young males are horny more often than not, does not mean that they ACT in ways that are disrespectful or degrading to women. This may mean, that they can’t control the quick thoughts that pop in their heads when they see an attractive female, but this does not mean this is the only, or even primary way in which they view that female. All it means is that it can be the first way, in a myriad of ways in which that male can see and judge that woman. And to quote, or at least paraphrase a line that I feel captures most young males is: If it wasn’t for women, I could’ve been a great man. But if it wasn’t for women, I wouldn’t have wanted to be a great man. ~ TC
