MAOA, Race, and Crime: A Simple Relationship?

2400 words

When I first got into HBD back in 2012, one of the first things I came across—along with the research on racial IQs from Rushton, Lynn, Jensen et al—was that the races differed in a gene called MAOA-L, which has a frequency in Caucasians at .1 percent (Beaver et al, 2013), 54 percent in Chinese people (Lu et al, 2013; as well as 77 percent for the 3r MAOA allele; Lea and Chambers, 2007), 56 percent in Maoris (Lea and Chambers 2007) while about 60-65 percent of Japanese people have the low-frequency version of this gene (Way and Lieberman, 2007).

So if these ethnies have a higher rate of this polymorphism and it is true that this gene causes crime, then the Chinese and Japanese should have the highest rates of crime in the world, since even apparently the effect of MAOA and violence and antisocial behavior is seen even without child abuse (Ficks and Waldman, 2014). Except East Asian countries have lower rates of crime (Rushton, 1995; Rushton and Whytney, 2002). Though, Japan’s low crime rate is relatively recent, and when compared with other countries on certain measures “Japan fares the same or worse when compared to other nations” (Barberet 2009, 198). This goes against a lot of HBD theory, and I will save that for another day. (Japan has a 99 percent prosecution rate, which could be due to low prosecutorial budgets; Ramseyer and Rasmusen, 2001. I will cover this in the future.)

The media fervor—as usual—gave the MAOA gene the nickname “the warrior gene“, which is extremely simplistic (I will have much more to say on ‘genes for’ any trait towards the end of the article). I will show how this is a very simplistic view.

The MAOA gene was first discovered in 1993 in a Dutch family who had a history of extreme violence going as far back as the 1890s. Since the discovery of this gene, it has been invoked as an ultimate cause of crime. However, as some hereditarians do note, MAOA only ’causes’ violence if one has a specific MAOA genotype and if they have been abused as a child (Caspi et al, 2002; Cohen et al, 2006; Beaver et al, 2009; Ferguson et al, 2011; Cicchetti, Rogosch, Thibodeau, 2012;). People have invoked these gene variants as ultimate causes of crime—that is, people who have the low-expressing MAOA variants are more likely to commit more crime—but the relationship is not so simple.

Maoris are more four times more likely to have the low-expressing gene variant than Europeans, the same holding for African Americans and Europeans (Lea and Chambers, 2007).

There is, however, a protective effect that protects whites (and not non-whites in certain cases) against antisocial behavior/violent attitudes if one has a certain genotype (Widom and Brzustowicz, 2006), though the authors write on page 688: “For non-whites, the effect of child abuse and neglect on the juvenile VASB was not significant (beta .08, SE .11, t 1.19, ns), whereas the effect of child maltreatment on lifetime VASB composite approached significance (beta .13, SE .12, t 1.86, p .06). For non-whites (see Figure 2), neither gene (MAOA) environment (child abuse and neglect) interaction was significant: juvenile VASB (beta .06, SE .28, t .67, ns) and lifetime VASB (beta .01, SE .29, t .14, ns).” So as you can see, there are mixed results. Whites seem to be protected against the effect of antisocial behavior and violence but only if they have a certain genotype (which implies that if they have the other genotype, then if abused they will show violent and antisocial behavior). So, we can see that the relationship between MAOA and criminal behavior is not as simple as some would make it out to be.

MAOA, like other genetic variants, of course, has been linked to numerous other traits. Steven J. Heine, author of the book DNA is Not Destiny: The Remarkable and Completely Misunderstood Relationship Between You and Your Genes:

However, any labels like “the warrior gene” are highly problematic because they suggest that the this gene is specifically associated with violence. It’s not, just as alleles from other genes do not only have one outcome. Pleiotropy is the term for how a single genetic variant can influence multiple different phenotypes. MAOA is highly pleiotropic: the traits and conditions potientially connected to the MAOA gene invlude Alzheimer’s. anoerxia, autism, body mass index, bone mineral density, chronic fatigue syndrome, depression, extraversion, hypertension, individualism, insomnia, intelligence, memory, neuroticism, obesity, openness to experience, persistence, restless leg syndrome, schizophrenia, social phobia, sudden infant death syndrome, time perception and voting behavior. (59) Perhaps it would be more fitting to call MAOA “the everything but the kitchen sink gene. (Heine, 2017: 195)

Something that I have not seen brought up when discussions of race, crime, and MAOA come up is that Japanese people have the highest chance—even higher than blacks, Maoris, and whites—to have the low repeat MAOA variant (Way and Lieberman) yet have lower rates of crime. So MAOA cannot possibly be a ‘main cause’ of crime. It is way more complex than that. “However intuitively satisfying it may be to explain cultural differences in violence in terms of genes“, Heine writes, “as of yet there is no direct evidence for this” (Heine, 2017: 196).

Numerous people have used ‘their genes’ in an attempt to get out of criminal acts that they have committed. A judge even knocked off one year off of a murder’s sentence since he found the evidence for the MAOA gene’s link to violence “particularly compelling.” I find it “particularly ridiculous” that the man got less time in jail than someone who ‘had a choice’ in his actions to murder someone. Doesn’t it seem ridiculous to you that someone gets less time in jail than someone else, all because he may have the ‘crime/warrior gene’?

Aspinwall, Brown, and Tabery (2012) showed that when evidence of a ‘biomechanic’ cause of violence/psychopathy was shown to the judges (n=191), that they reduced their sentences by almost one year if they were reading a story in which the accused was found to have the low-repeat MAOA allele (13.93 to 12.83 years). So, as you can see, this can sway judges’ perception into giving one a lighter sentence since they believe that the evidence shows that one ‘can not control themselves’, which results in the judge giving assailants lighter sentences because ‘it’s in their genes’.

Further, people would be more lenient on sentences for criminals who are found to have these ‘criminal genes’ than those who were found to not have them (Cheung and Heine, 2015). Monterosso, Royzman, and Schwartz (2010) also write: “Physiologically explained behavior was more likely to be characterized as “automatic,” and willpower and character were less likely to be cited as relevant to the behavior. Physiological explanations of undesirable behavior may mitigate blame by inviting nonteleological causal attributions.” So, clearly, most college students would give a lighter sentence if the individual in question were found to have ‘criminal genes’. But, if these genes really did ’cause’ crime, shouldn’t they be given heavier sentences to keep them on the inside more so those with the ‘non-criminal genes’ don’t have to suffer from the ‘genetically induced’ crime?

Heine (2017: 198-199) also writes:

But is someone really less any responsible for their actions if his or her genes are implicated? A problem with this argument is that we would be hard-pressed to find any actions that we engage in where our genes are not involved—our behaviors do not occur in any gene-free zones. Or, consider this: there actually is a particular genetic variant that, if you possess it, makes you about 40 times more likely to engage in same-sex homicides than those who possess a different variant. (66) It’s known as the Y chromosome—that is, people who possess it are biologically male. Given this, should we infer that Y chromosomes cause murders, and thus give a reduced sentence to anyone who is the carrier of such a chromosome because he is really not responsible for his actions? The philosopher Stephen Morse calls the tendency to excuse a crime because of a biological basis the “fundamental psycholegal error.” (67) The problem with this tendency is that it involves separating yout genes from yourself. Saying “my genes made me do it” doesn’t make sense because there is no “I” that is independent of your genetic makeup. But curiously, once genes are implicaed, people see, to feel that the accused is no longer fully in control of his or her actions.

Further, in the case of a child pornographer, one named Gary Cossey, the court said:

The court predicted that some fifty years from now Cossey’s offense conduct would likely be discovered to be caused by “a gene you were born with. And it’s not a gene you can get rid of.” The court expressed its belief that although Cossey was in therapy, it “can only lead, in my view, to a sincere effort on your part to control, but you can’t get rid of it. You are what you’re born with. And that’s the only explanation for what I see here.”

However, this judge punished Cossey more severely due to the ‘possibility’ that scientists may find ‘genes for’ child pornography use in 50 years. Cossey was then given another, unbiased judge, and was given a ‘more lenient’ sentence than the genetic determinist judge did.

Sean Last over at The Alternative Hypothesis is also a big believer in this so-called MAOA-race difference that explains racial differences in crime. However, as reviewed above (and as he writes), MAOA can be called the “everything but the kitchen sink gene” (Heine, 2017: 195), as I will touch on briefly below, to attribute ’causes’ to genes is not the right way to look at them. It’s not so easy to say that since one ‘has the warrior gene’ that they’d automatically be violent. Last cites a study saying that even those who have the MAOA allele who were not abused showed higher rates of violent behavior (Ficks and Waldman, 2014). They write (pg. 429):

The frequency of the ‘‘risk’’ allele in nonclinical samples of European ancestry ranges from 0.3 to 0.4, although the frequency of this allele in individuals of Asian and African ancestry appears to be substantially higher (*0.6 in both groups; Sabol et al. 1998).

So, why don’t Asians have higher rates of crime—along with blacks—if MAOA on its own causes violent and antisocial behavior? Next I know that someone would claim that “AHA! TESTOSTERONE ALSO MEDIATES THIS RELATIONSHIP!!” However, as I’ve talked about countless times (until I’m blue in the face), blacks do not have/have lower levels of testosterone than whites (Richards et al, 1992Gapstur et al, 2002; Rohrmann et al, 2007; Mazur, 2009; Lopez et al, 2013; Hu et al, 2014; Richard et al, 2014). Though young black males have higher levels of testosterone due to the environment (honor culture) (Mazur, 2016). So that canard cannot be trotted out.

All in all, these simplistic and reductionist approaches to ‘figuring out’ the ’causes’ of crime do not make any sense. To point at one gene and say that this is ‘the cause’ of that do not make sense.

One last point on ‘genes as causes’ for behavior. This is something that deserves a piece of its own, but I will just provide a quote from Eva Jablonska and Marion Lamb’s book Evolution in Four Dimensions: Genetic, Epigenetic, Behavioral, and Symbolic Variation in the History of Life (Jablonska and Lamb, 2014: 17; read chapter one of the book here; I have the nook version so the page number may be different):

Although many psychiatrists, biochemists, and other scientists who are not geneticists (yet express themselves with remarkable facility on genetic issues) still use the language of genes as simple causal agents, and promise their audience rapid solutions to all sorts of problems, they are no more than propagandists whose knowledge or motives must be suspect. The geneticists themselves now think and talk (most of the time) in terms of genetic networks composed of tens or hundreds of genes and gene products, which interact with each other and together affect the development of a particular trait. They recognize that whether or not a trait (a sexual preference, for example) develops does not depend, in the majority of cases, on a difference in a single gene. It involves interactions among many genes, many proteins and other types of molecule, and the environment in which an individual develops.

So to say that those who have low-functioning MAOA variants have an ‘excuse’ as to why they commit crime is incorrect. I know that most people know this, but when you read some people’s writings on things like this it’s like they think that these singular genes/polymorphisms/etc cause these things on their own. In actuality, you need to look at how the whole system interacts with these things, and not reduce whole complex physiological systems to a sum of its parts. This is why implicating singular genes/polymorphisms as explanations for racial differences in crime does not make sense (as can be seen with the Japanese example).

To reduce behaviors simply to gene X and not look at the whole system does not make any sense. There are no ‘genes for’ anything, except a few Mendelian diseases (Ropers, 2010). Stating that certain genes ’cause’ X, as I have shown does not make sense and, wrongly, in my opinion, gives criminals less of a sentencing since judges find stuff like this ‘very compelling’. If that’s the case, why implicate any murderer? ‘Their genes made them do it’, right? Though, things are not that simple to implicate one gene as a cause for crime or any other complex behavior; in this sense—like for most things to do with the human body—holism makes way more sense and not reductionism. We need to look at how these genes that are ‘implicated’ in criminal behavior interact with the whole system. Only then can we understand the causes of criminal behavior. Looking at singular genes impedes us from figuring out the true underlying reasons why people commit crime.

Remember: we can’t blame “warrior genes” for violent crime. If someone does have a ‘genetic predisposition to crime’ from the MAOA gene, then wouldn’t it make more sense to give them more time? Though, the relationship is not so simple as I have covered. So to close, there is no ‘simple relationship’ between race, crime and MAOA. Not in the way that other hereditarians would like you to believe. Because if this relationship were so simple, then East Asians (Chinese, Japanese) would have the highest rates of crime, and they do not.

Testosterone: “The Crime Gene?”

1150 words

I came across this video on YouTube last night by a geneticist/science writer Steve Jones. He is also the Emeritus Professor of genetics at University College London. This makes what he says in the video I will speak about below very troubling—especially to a man of his caliber with the knowledge he has—views he has on the hormone.

In the very beginning of the video titled Testosterone and Crime: What Can Genes Tell Us About Behavior?Jones says “But in fact, there are genes—there is a gene—for crime, which causes nearly all the crime, and is widely used and we understand a great deal about it. It’s a chemical gene it produces a particular chemical, which we understand in detail is the chemical testosterone. Testosterone—we all have it but some of us have rather more than others—testosterone is of course a gene that is made—switched on by the Y chromosome and makes males male. Women have a small amount but only a small amount and as they get older … Now testosterone is a dangerous, dangerous thing to have. I don’t recommend it, those of you who have it, don’t get it. And if you’ve got some, don’t get any more.” What bullshit! This guy is a literal genetics Ph.D. saying this; this is proof that knowledge/educational attainment does not stop you from saying dumb, untrue things.

I don’t know that this character does it, but certainly plenty of bodybuilders inject steroids—testosterone—into themselves. They damage themselves severely. Their life expectancy goes down strikingly. They die for all those male reasons. They die from violence, they die from suicide, they die from car accidents, they die from heart disease, all those things are true of males. … But even if you look at males and females in general, there is kind of a depressing picture for half of the room, I’m not sure which half.” Jones then talks about how men die at a much higher rate than women for a slew of reasons. This is his logic: Men have higher testosterone than women. Testosterone is shown to cause violence, aggression, heart disease, risk-taking, etc. Men have way more testosterone than women. Therefore testosterone is the reason why men die more than women and commit more violence than women. This is horrible logic—coming from a geneticist no less!

Men actually—less expectedly perhaps—are much less good at dealing with parasites and infectious disease than women are. And that’s because testosterone—the male hormone—suppresses the immune system. Now the immune system fights off the parasites and we don’t do nearly as well.” There is actually some empirical data for his argument here. Back in 2013, it was shown that testosterone, gene expression, and the immune system were linked. They discovered that higher levels of testosterone prevented Module 52 genes from turning on. So higher levels of testosterone result in more Module 52 expression. Testosterone also does exert immune-suppressing effects, “increasing the severity of malaria, leishmaniasis, amebiasis, and tuberculosis, while at the same time supporting the clearance of toxoplasmosis (Bernin & Lotter, 2014; Nhamoyebonde & Leslie, 2014)” (Giefing-Kroll et al, 2015). The suppressive effects of testosterone on the immune system and how down-regulates “the systemic immune response by cell type specific effects in the context of immunological disorders.” (Trigunaite, Dimo, and Jorgensen, 2015).

The effects of testosterone replacement therapy (TRT) on the immune system have not been looked into, but it has a positive effect on elderly men (Osterberg, Bernie, and Ramasamy, 2014). However, Braude, Tang-Martinez, and Taylor (1999) challenge the wisdom that testosterone is an immuno-depressor. This is Jones’ only claim that is not outright wrong; there is data out there for both positions (of course I think that Braude, Tang-Martinez and Taylor, 1999 drive a solid argument against the testosterone-causes-immuno-suppression hypothesis).

The Jones says one of the dumbest things I’ve ever heard “And men, of course, are murdered much more than women. And who murders them—of course—other men. … Men murder at a much higher rate than women. … And that effect is striking—that effect is true worldwide—all over the world men, testosterone, murder at 10 times the rate of women. … So it’s a universal, it’s a biological universal, it’s clearly due to testosterone. There’s no question. The evidence is absolutely clear. So it’s a genetic phenomenon, it’s a gene for crime.” Should I be nice here and assume that whatever ‘gene’ he’s proposing that ’causes’ testosterone production actually causes the crime? Or should I take what he said at face value—that testosterone is a literal gene that causes crime? I think I’ll go with the second one.

It’s certainly genetic, it’s also environmental. And you can’t disentangle it. You can change part of it—the environment—you can’t change the other part—the genes. And I always find it kind of odd that the public is so interested in the bit you can’t change—the genes—and is so uninterested in the bit you can—the environment.” This is wrong. Not all of it, but most of it. I don’t think that people are more interested in genes and toss aside environment—especially for testosterone. Because, as I documented yesterday, hereditarians assume that since testosterone has a heritability of around .6 then it must be mostly genetic in nature. This is wrong. As Jones said, the environment effects testosterone production too (though he didn’t go into the mechanisms).

The Left goes to the environment side—change the environment, change hormone production (this is true)—whereas the Right goes to the genes side—can’t change genes and environment is a product of genes so nothing can be done. (Oversimplified, don’t crucify me.) Both are wrong. Strong genetic determinism (gene G almost always leads to the development of trait T. (G increases the probability of T and the probability of T, given G, is 95% or greater) doesn’t make sense because a large majority of traits are moderately or weakly determined by genetics (Resnick and Vorhaus, 2006).

In sum, Jones is clueless about testosterone. He only really said one thing that is not outright wrong (but it is questionable). It doesn’t cause crime, it doesn’t cause men to murder more. The press has gotten all of these views into people’s heads because they want to demonize men—and the hormone that is largely responsible for male-ness. It’s incredible that this guy is both a geneticist, science writer and professor of genetics and still calls testosterone a ‘gene’ saying that it is responsible for ‘most of the crime’ committed. Anyone who has been reading this blog for the past year or so since I have began revising many of my main views knows how wrong this is. People really need to get a clue on testosterone and stop spreading bullshit. I know that I’ll have to keep correcting misconceptions on testosterone for a good long time (like with r/K theory) but I enjoy writing about both things so it’s not too big a deal. I just wish people would actually educated themselves on basic physiology so that the trainwreck of a video that Jones made does not get made.

No, Black Women Do Not Have Higher Testosterone than White Women (And More On Hereditarian Claims on Racial Testosterone Differences)

1850 words

It has been over a year since I wrote the article Black Women and Testosterone, and I really regret it. Yes, I did believe that black women had higher levels of testosterone than white women due to one flimsy study and another article on pregnant black women. I then wised up to the truth about testosterone and aggression/crime/race/sex and revised the articles (like I have done with r/K selection theory). However, after I revised my views on the supposed differences in testosterone between black men/white men and black women/white women, people still cite the article, disregarding the disclaimer at the top of the article. I quoted Mazur (2016), who writes (emphasis mine):

The pattern [high testosterone] is not seen among teenage boys or among females.

There is no indication of inordinately high T among young black women with low education.

Honor cultures are cast as male affairs, but with T data in hand for both sexes, it is worth exploring whether or not a similar pattern exists among women. Mean T was calculated as a function of age for the four combinations of race and education used in Table 1 but now for women. All plots show T declining with age, from about 35 ng/dL in the 20–29 age group to about 20 ng/dL among women 60 years and older. The four plots essentially overlap without discernible differences among them. Given the high skew of T among adult females, both raw and ln-transformed values were analyzed with similar results. There is no indication of inordinately high T among young black women with low education.

In the present study, at least, the sexes differ because the very high T seen among young black men with low education does not occur among young black women with low education.

This is very clear… Mazur (2016) analyzed the NHANES 2011-2012 data and this is what he found. I understand that most HBD bloggers do believe this, well, like a lot of their strong assertions (which I have rebutted myself), they’re wrong. They don’t get it. They do not understand the hormone.

The reason why I’m finally writing this (which is long overdue) is that I saw a referral from this website today: https://www.minds.com/RedPillTV who writes about the aforementioned black women and testosterone article:

It is known that blacks have the highest levels of testosterone out of the major races of humanity. However, what’s not known is that black women have higher rates than white women. The same evolutionary factors that make it possible for black men to have high testosterone make it possible for women as well.

https://notpoliticallycorrect.me/2016/09/06/black-women-and-testosterone/

…..No. It seems that people just scroll on by the disclaimer at the top that is bolded and italicized and just go to the (now defunct) article and attempt to prove their assertion that black women have higher testosterone than white women with an article that I have stated myself I no longer believe and have provided the rationale/data for the position. This shows that people have their own biases and no matter what the author writes about their views that have changed due to good arguments/data, they will still attempt to use the article to prove their assertion.

I’ve written at length that testosterone does not cause 1) aggression, 2) crime and 3) prostate cancer. People are scared of testosterone mostly due to the media fervor of any story that may have a hint of ‘toxic masculinity’. They (most alt-righters) are scared of it because of Lynn/Rushton/Templer/Kanazawa bullshit on the hormone. Richard Lynn doesn’t know what he’s talking about on testosterone. No, Europeans did not need lower levels of aggression in the cold; Africans didn’t need higher levels of aggression (relative to Europeans) to survive in the tropics. The theory that supposed differential testosterone differences between the races are “the physiological basis in males of the racial differences in sexual drive which form the core of the different r/K reproduction strategies documented by J.P. Rushton” (Lynn, 1990: 1203). The races, on average, do not differ in testosterone as I have extensively documented. So hereditarians like Lynn and others need to look for other reasons to explain blacks’ higher rate of sexual activity.

Rushton’s views on the testosterone and supposed r/K continuum have been summarily rebutted by me. These psychologists’ views on the hormone (that they don’t understand the production of nor do they understand the true reality of the differences between the races) are why people are afraid of testosterone. No, testosterone is not some ‘master switch’ as Rushton (1999) asserts. Rushton asserts that racial differences in temperament are mediated by the hormone testosterone. He further dives into this assertion stating “Testosterone level correlates with temperament, self-concept, aggression, altruism, crime, and sexuality, in women as well as in men (Harris, Rushton, Hampson, & Jackson, 1996). It may ‘correlate’ with aggression and crime, but as I have documented, they do not cause either.

The aggression/testosterone correlation is only .08 (Archer, Graham-Kevan, and Davies, 2005). Furthermore, the diurnal variation in testosterone does not directly correlate to when testosterone levels are highest in the day (at 8 am and drop thereafter), with adults peaking in crime at 10 pm and kids at 3 pm, with rises at 8 pm and 12 pm (not surprisingly, kids go in to school around 8 am, go to recess at 12 and leave at 3).

If you’ve read as much Rushton as I have, you’ll notice that he begins to sound like a broken record when talking about certain things. One of the most telling is Rushton’s repeated assertions that blacks average 3-19 percent higher testosterone than whites. The 3 percent number comes from Ellis and Nyborg (1992) and the 19 percent number comes from Ross et al (1986) (which Rushton should know that after adjustments for confounding, it decreased to 13 percent). These are the only studies that hereditarians ever cite for these claims that blacks average higher testosterone than whites. That seems a bit fishy to me. Cite a 30-year-old study along with a 25-year-old study (with such huge variation from Rushton and those who cite him for this matter—3-19 percent!!) as ‘proof’ that blacks average such higher levels of testosterone in comparison to whites.

Ross et al (1986) is one of the most important studies to rebut for this hereditarian claim that testosterone causes all of these maladies in black American populations. Ross et al (1986) propose that higher levels of the hormone lead to the higher rates of prostate cancer in black American populations. However, meta-analyses do not show this (Zagars et al, 1998; Sridhar et al, 2010).

Rushton et al’s assertions—largely—lie on this supposed testosterone difference between the races and how it supposedly leads to higher rates of crime, prostate cancer, aggression, and violence. However, the truth of the matter is, this is all just hereditarian bullshit. Larger analyses—as I have extensively documented—do not show this trend. And even accepting the claim that blacks have, say, 19 percent higher levels of testosterone than whites, it still would not explain the supposed prostate cancer rates between the races (Stattin et al, 2003Michaud, Billups, and Partin, 2015). Even if blacks had 19 percent higher testosterone than whites, it would not explain higher levels of crime nor aggression due to such a hilariously low correlation of .08 (Archer, Graham-Kevan, and Davies, 2005).

Finally, I have a few words for Michael Hart and his (albeit sparse) claims on testosterone in his 2007 book Understanding Human History.

Hart (2007) writes:

(Many of these differences in sexual behavior may be a consequence of the fact that
blacks, on average, have higher levels of testosterone than whites.7) (pg. 127)

And….. footnote number 7 is…. surprisingly (not): 7) Ross, R., et al. (1986). Not going to waste my time on this one, again. I’ve pointed out numerous flaws in the study. (I will eventually review the whole thing.)

It seems unlikely, though, that the higher testosterone level in blacks — which is largely genetic in origin — has no effect on their sexual behavior (pg. 128; emphasis mine)

This is bullshit. People see the moderately high heritability of testosterone (.60; Harris, Vernon, and Boomsma, 1998) and jump right to the “It’s genetics!!!” canard without even understanding its production in the body (it is a cholesterol-based hormone which is indirectly controlled by DNA, there are no ‘genes for’ testosterone). Here are the steps: 1) DNA codes for mRNA; 2) mRNA codes for the synthesis of an enzyme in the cytoplasm; 3) luteinizing hormone stimulates the production of another messenger in the cell when testosterone is needed; 4) this second messenger activates the enzyme; 5) the enzyme then converts cholesterol to testosterone

I have documented numerous lines of evidence showing that testosterone is extremely sensitive to environmental factors (Mazur and Booth, 1998; Mazur, 2016), and due to the homeodynamic physiology we have acquired due to ever-changing environments (Richardson, 2017), this allows our hormones to up- or down-regulate depending on what occurs in the environment. The quote from Hart is bullshit; he doesn’t know what he’s talking about.

For females in Siberia, the disadvantages of failing to find a man who would
provide for her and her children during their childhood were much greater than they were in tropical climates, and females who were not careful to do so were much less likely to pass on their genes. Furthermore, because females in harsh climates were so demanding on this point, males who seemed unlikely to provide the needed assistance found it hard to find mates. In other words, there was a marked sexual selection against such males. Such selection could result, for example, in the peoples living in northerly climates gradually evolving lower levels of testosterone than the peoples living in subSaharan Africa. (pg. 131)

This is a bullshit just-so story. Africans in Africa have lower levels of testosterone than Western men (Campbell, O’Rourke, and Lipson, 2003Lucas and Campbell, and Ellison, 2004Campbell, Gray, and Ellison, 2006).

Note also that a difference in testosterone level frequently affects not
only the sexual behavior of a young male, but also his aggressiveness.

No it does not (Archer, Graham-Kevan, and Davies, 2005).

Thankfully, that’s all he wrote about testosterone. There is so much bullshit out there. Though, people who like and seek out the truth will learn that there are no racial differences and that testosterone does not cause crime/aggression/prostate cancer and that it’s just hereditarian bullshit.

The evidence I have amassed and the arguments I have given point to a few things: 1) the races do not differ in testosterone/there is a small negligible difference; 2) testosterone does not cause crime; 3) testosterone does not cause aggression; 4) black women do not have higher levels of testosterone than white women; 5) high levels of testosterone do not cause prostate cancer; and 6) even allowing a 19 percent black/white difference will not have hereditarian claims hold true.

So for anyone who comes across my old articles on testosterone and sex/race, do a bit more reading of my newer material here to see my new viewpoints/arguments. DO NOT cite these articles as proof for your claims of higher levels of black men/women. DO cite the old articles ALONG WITH the new ones to show how and why my views changed along with the studies I have cited that changed my view. (Actually understanding the production of testosterone in the body was a huge factor too, which I talk about in Why Testosterone Does Not Cause Crime.)

Responses to The Alternative Hypothesis and Robert Lindsay on Testosterone

2300 words

I enjoy reading what other bloggers write about testosterone and its supposed link to crime, aggression, and prostate cancer; I used to believe some of the things they did, since I didn’t have a good understanding of the hormone nor its production in the body. However, once you understand how its produced in the body, then what others say about it will seem like bullshit—because it is. I’ve recently read a few articles on testosterone from the HBD-blog-o-sphere and, of course, they have a lot of misconceptions in them—some even using studies I have used myself on this blog to prove my point that testosterone does not cause crime!! Now, I know that most people don’t read studies that are linked, so they would take what it says on face value because, why not, there’s a cite so what he’s saying must be true, right? Wrong. I will begin with reviewing an article by someone at The Alternative Hypothesis and then review one article from Robert Lindsay on testosterone.

The Alternative Hypothesis

Faulk has great stuff here, but the one who wrote this article, Testosterone, Race, and Crime1) doesn’t know what he’s talking about and 2) clearly didn’t read the papers he cited. Read this article, you’ll see him make bold claims using studies I have used for my own arguments that testosterone doesn’t cause crime! Let’s take a look.

One factor which explains part of why Blacks have higher than average crime rates is testosterone. Testosterone is known to cause aggression, and Blacks are known to at once have more of it and, for genetic reasons, to be more sensitive to its effects.

  1. No it doesn’t.
  2. Testosterone is known to cause aggression“, but that’s the thing: it’s only known that it ’causes’ aggression, it really doesn’t.
  3. Evidence is mixed on blacks being “… for genetic reasons … more sensitive to its effects” (Update on Androgen Receptor gene—Race/History/Evolution Notes).

Testosterone activity has been linked many times to aggression and crime. Meta-analyses show that testosterone is correlated with aggression among humans and non human animals (Book, Starzyk, and Quinsey, 2001).

Why doesn’t he say what the correlation is? It’s .14 and this study, while Archer, Graham-Kevan and Davies, (2005) reanalyzed the studies used in the previous analysis and found the correlation to be .08. This is a dishonest statement.

Women who suffer from a disease known as congenital adrenal hyperplasia are exposed to abnormally high amounts of testosterone and are abnormally aggressive.

Abnormal levels of androgens in the womb for girls with CAH are associated with aggression, while boys with and without CAH are similar in aggression/activity level (Pasterski et al, 2008), yet black women, for instance, don’t have higher levels of testosterone than white women (Mazur, 2016). CAH is just girls showing masculinized behavior; testosterone doesn’t cause the aggression (See Archer, Graham-Kevan and Davies, 2005)

Artificially increasing the amount of testosterone in a person’s blood has been shown to lead to increases in their level of aggression (Burnham 2007Kouri et al. 1995).

Actually, no. Supraphysiological levels of testosterone administered to men (200 and 600 mg weekly) did not increase aggression or anger (Batrinos, 2012).

 Finally, people in prison have higher than average rates of testosterone (Dabbs et al., 2005).

Dabbs et al don’t untangle correlation from causation. Environmental factors can explain higher testosterone levels (Mazur, 2016) in inmates, and even then, some studies show socially dominant and aggressive men have the same levels of testosterone (Ehrenkraz, Bliss, and Sheard, 1974).

Thus, testosterone seems to cause both aggression and crime.

No, it doesn’t.

Why Testosterone Does Not Cause Crime

Testosterone and Aggressive Behavior

Can racial differences in circulating testosterone explain racial differences in crime?—Race/History/Evolution Notes

Furthermore, of the studies I could find on testosterone in Africans, they have lower levels than Western men (Campbell, O’Rourke, and Lipson, 2003Lucas and Campbell, and Ellison, 2004Campbell, Gray, and Ellison, 2006) so, along with the studies and articles cited on testosterone, aggression, and crime,  that’s another huge blow to the testosterone/crime/aggression hypothesis.

Richard et al. (2014) meta-analyzed data from 14 separate studies and found that Blacks have higher levels of free floating testosterone in their blood than Whites do.

They showed that blacks had 2.5 to 4.9 percent higher testosterone than whites, which could not explain the higher prostate cancer incidence (which meta-analyses call in to question; Sridhar et al 2010; Zagars et al 1998). That moderate amount would not be enough to cause differences in aggression either.

Exacerbating this problem even further is the fact that Blacks are more likely than Whites to have low repeat versions of the androgen receptor gene. The androgen reception (AR) gene codes for a receptor by the same name which reacts to androgenic hormones such as testosterone. This receptor is a key part of the mechanism by which testosterone has its effects throughout the body and brain.

No they’re not.

The rest of the article talks about CAG repeats and aggressive/criminal behavior, but it seems that whites have fewer CAG repeats than blacks.

Robert Lindsay

This one is much more basic, and tiring to rebut but I’ll do it anyway. Lindsay has a whole slew of articles on testosterone on his blog that show he doesn’t understand the hormone, but I’ll just talk about this one for now: Black Males and Testosterone: Evolution and Perspectives.

It was also confirmed by a recent British study (prostate cancer rates are somewhat lower in Black British men because a higher proportion of them have one White parent)

Jones and Chinegwundoh (2014) write: “Caution should be taken prior to the interpretation of these results due to a paucity of research in this area, limited accurate ethnicity data, and lack of age-specific standardisation for comparison. Cultural attitudes towards prostate cancer and health care in general may have a significant impact on these figures, combined with other clinico-pathological associations.

This finding suggests that the factor(s) responsible for the difference in rates occurs, or first occurs, early in life. Black males are exposed to higher testosterone levels from the very start.

In a study of women in early pregnancy, Ross found that testosterone levels were 50% higher in Black women than in White women (MacIntosh 1997).

I used to believe this, but it’s much more nuanced than that. Black women don’t have higher levels of testosterone than white women (Mazur, 2016; and even then Lindsay fails to point out that this was pregnant women).

According to Ross, his findings are “very consistent with the role of androgens in prostate carcinogenesis and in explaining the racial/ethnic variations in risk” (MacIntosh 1997).

Testosterone has been hypothesized to play a role in the etiology of prostate cancer, because testosterone and its metabolite, dihydrotestosterone, are the principal trophic hormones that regulate growth and function of epithelial prostate tissue.

Testosterone doesn’t cause prostate cancer (Stattin et al, 2003Michaud, Billups, and Partin, 2015). Diet explains any risk that may be there (Hayes et al, 1999; Gupta et al, 2009Kheirandish and Chinegwundoh, 2011; Williams et al, 2012Gathirua-Mingwai and Zhang, 2014). However in a small population-based study on blacks and whites from South Carolina, Sanderson et al (2017) “did not find marked differences in lifestyle factors associated with prostate cancer by race.”

Regular exercise, however, can decrease PCa incidence in black men (Moore et al, 2010). A lot of differences can be—albeit, not too largely— ameliorated by environmental interventions such as dieting and exercising.

Many studies have shown that young Black men have higher testosterone than young White men (Ellis & Nyborg 1992; Ross et al. 1992; Tsai et al. 2006).

Ellis and Nyborg (1992) found 3 percent difference. Ross et al (1992) have the same problem as Ross et al (1986), which used University students (~50) for their sample. They’re not representative of the population. Ross et al (1992) also write:

Samples were also collected between 1000 h and 1500 h to avoid confounding
by any diurnal variation in testosterone concentrations.

Testosterone levels should be measured near to 8 am. This has the same time variation too, so I don’t take this study seriously due to that confound. Assays were collected “between” the hours of 10 am and 3 pm, which means it was whenever convenient for the student. No controls on activities, nor attempting to assay at 8 am. People of any racial group could have gone at whatever time in that 5 hour time period and skew the results. Assaying “between” those times completely defeats the purpose of the study.

 

This advantage [the so-called testosterone advantage] then shrinks and eventually disappears at some point during the 30s (Gapstur et al., 2002).

Gapstur et al (2002) help my argument, not yours.

This makes it very difficult if not impossible to explain differing behavioral variables, including higher rates of crime and aggression, in Black males over the age of 33 on the basis of elevated testosterone levels.

See above where I talk about crime/testosterone/aggression.

Critics say that more recent studies done since the early 2000’s have shown no differences between Black and White testosterone levels. Perhaps they are referring to recent studies that show lower testosterone levels in adult Blacks than in adult Whites. This was the conclusion of one recent study (Alvergne et al. 2009) which found lower T levels in Senegalese men than in Western men. But these Senegalese men were 38.3 years old on average.

Alvergne, Fauri, and Raymond (2009) show that the differences are due to environmental factors:

This study investigated the relationship between mens’ salivary T and the trade-off between mating and parenting efforts in a polygynous population of agriculturists from rural Senegal. The men’s reproductive trade-offs were evaluated by recording (1) their pair-bonding/fatherhood status and (2) their behavioral profile in the allocation of parental care and their marital status (i.e. monogamously married; polygynously married).

They also controlled for age, so his statement “But these Senegalese men were 38.3 years old on average” is useless.

These critics may also be referring to various studies by Sabine Rohrmann which show no significance difference in T levels between Black and White Americans. Age is poorly controlled for in her studies.

That is one study out of many that I reference. Rohrmann et al (2007) controlled for age. I like how he literally only says “age is poorly controlled for in her studies“, because she did control for age.

That study found that more than 25% of the samples for adults between 30 and 39 years were positive for HSV-2. It is likely that those positive samples had been set aside, thus depleting the serum bank of male donors who were not only more polygamous but also more likely to have high T levels. This sample bias was probably worse for African American participants than for Euro-American participants.

Why would they use diseased samples? Do you even think?

Young Black males have higher levels of active testosterone than European and Asian males. Asian levels are about the same as Whites, but a study in Japan with young Japanese men suggested that the Japanese had lower activity of 5-alpha reductase than did U.S. Whites and Blacks (Ross et al 1992). This enzyme metabolizes testosterone into dihydrotestosterone, or DHT, which is at least eight to 10 times more potent than testosterone. So effectively, Asians have the lower testosterone levels than Blacks and Whites. In addition, androgen receptor sensitivity is highest in Black men, intermediate in Whites and lowest in Asians.

Wu et al (1995) show that Asians have the highest testosterone levels. Evidence is also mixed here as well. See above on AR sensitivity.

Ethnicmuse also showed that, contrary to popular belief, Asians have higher levels of testosterone than Africans who have higher levels of testosterone than Caucasians in his meta-analysis. (Here is his data.)

The Androgen Receptor and “masculinization”

Let us look at one study (Ross et al 1986) to see what the findings of a typical study looking for testosterone differences between races shows us. This study gives the results of assays of circulating steroid hormone levels in white and black college students in Los Angeles, CA. Mean testosterone levels in Blacks were 19% higher than in Whites, and free testosterone levels were 21% higher. Both these differences were statistically significant.

Assay times between 10 am and 3 pm, unrepresentative sample of college men, didn’t have control for waist circumference. Horribly study.

A 15% difference in circulating testosterone levels could readily explain a twofold difference in prostate cancer risk.

No, it wouldn’t (if it were true).

Higher testosterone levels are linked to violent behavior.

Causation not untangled.

Studies suggest that high testosterone lowers IQ (Ostatnikova et al 2007). Other findings suggest that increased androgen receptor sensitivity and higher sperm counts (markers for increased testosterone) are negatively correlated with intelligence when measured by speed of neuronal transmission and hence general intelligence (g) in a trade-off fashion (Manning 2007).

Who cares about correlations? Causes matter more. High testosterone doesn’t lower IQ. Racial differences in testosterone are tiring to talk about now, but there are still a few more articles I need to rebut.

Conclusion

Racial differences in testosterone don’t exist/are extremely small in magnitude (as I’ve covered countless times). The one article from TAH literally misrepresents studies/leaves out important figures in the testosterone differences between the two races to push a certain agenda. Though if you read the studies you see something completely different. It’s the same with Lindsay. He misunderstood a few studies to push his agenda about testosterone and crime and prostate cancer. They’re both wrong, though.

Can racial differences in circulating testosterone explain racial differences in crime?—Race/History/Evolution Notes

Racial differences in testosterone are tiring to talk about now, but there are still a few more articles I need to rebut. People read and write about things they don’t understand, which is the cause of these misconceptions with the hormone, as well as, of course, misinterpreting studies. Learn about the hormone and you won’t fear it. It doesn’t cause crime, prostate cancer nor aggression; these people who write these articles have one idea in their head and they just go for it. They don’t understand the intricacies of the endocrine system and how sensitive it is to environmental influence. I will cover more articles that others have written on testosterone and aggression to point out what they got wrong.

The ENA Theory: On Testosterone and Aggressive Behavior by Race/Ethnicity

3250 words

A commenter by the name of bbloggz alerted me to a new paper by Lee Ellis published this year titled Race/ethnicity and criminal behavior: Neurohormonal influences in which Ellis (2017) proposed his theory of ENA (evolutionary neuroandrogenic theory) and applied it to racial/ethnic differences in crime. On the face, his theory is solid and it has great explanatory power for the differences in crime rates between men and women, however, there are numerous holes in the application of the theory in regards to racial/ethnic differences in crime.

In part I, he talks about racial differences in crime. No one denies that, so on to part II.

In part II he talks about environmental causes for the racial discrepancies, that include economic racial disparities, racism and societal discrimination and subordination, a subculture of violence (I’ve been entertaining the honor culture hypothesis for a few months; Mazur (2016) drives a hard argument showing that similarly aged blacks with some college had lower levels of testosterone than blacks with less than high school education which fits the hypothesis of honor culture. Though Ellis’ ENA theory may account for this, I will address this below). However, if the environment that increases testosterone is ameliorated (i.e., honor culture environments), then there should be a subsequent decrease in testosterone and crime, although I do believe that testosterone has an extremely weak association with crime, nowhere near high enough to account for racial differences in crime, the culture of honor could explain a good amount of the crime gap between blacks and whites.

Ellis also speaks about the general stress/strain explanation, stating that blacks have higher rates of self-esteem and Asians the lowest, with that mirroring their crime rates. This could be seen as yet another case for the culture of honor in that blacks with a high self-esteem would feel the need to protect their ‘name’ or whatever the case may be and feel the need for physical altercation based on their culture.

In part III, Ellis then describes his ENA theory, which I don’t disagree with on its face as it’s a great theory with good explanatory power but there are some pretty large holes that he rightly addresses. He states that, as I have argued in the past, females selected men for higher rates of testosterone and that high rates of testosterone masculinize the brain, changing it from its ‘default feminine state’ and that the more androgens the brain is exposed to, the more likely it is for that individual to commit crime.

Strength

Ellis cites a study by Goodpaster et al (2006) in which he measured the races on the isokinetic dynamometry, pretty much a leg extension. However, one huge confound is that participants who did not return for follow-up were more likely to be black, obese and had more chronic disease (something that I have noted before in an article on racial grip strength). I really hate these study designs, but alas, it’s the best we have to go off of and there are a lot of holes in them that must be addressed. Though I applaud the researchers’ use of the DXA scan (regular readers may recall my criticisms on using calipers to assess body fat in the bench press study, which was highly flawed itself; Boyce et al, 2014) to assess body fat as it is the gold standard in the field.

Ellis (2017: 40) writes: “as brain exposure to testosterone surges at puberty, the prenatally-programmed motivation to strive for resources, status, and mating opportunities will begin to fully activate.” This is true on the face, however as I have noted the correlation between physical aggression and testosterone although positive is low at .14 (Archer, 1991; Book et al, 2001). Testosterone, as I have extensively documented, does cause social dominance and confidence which do not lead to aggression. However, when other factors are coupled with high testosterone (as noted by Mazur, 2016), high rates of crime may occur and this may explain why blacks commit crime; a mix of low IQ, high testosterone and low educational achievement making a life of crime ‘the smart way’ to live seeing as, as Ellis points out, and that intelligent individuals find legal ways to get resources while less intelligent individuals use illegal ways.

ENA theory may explain racial differences in crime

In part IV he attempts to show how his ENA theory may explain racial differences in crime—with testosterone sitting at the top of his pyramid. However, there are numerous erroneous assumptions and he does rightly point out that more research needs to be done on most of these variables and does not draw any conclusions that are not warranted based on the data he does cite. He cites one study in which testosterone levels were measured in the amniotic fluid of the fetus. The sample was 59 percent white and due to this, the researchers lumped blacks, ‘Hispanics’ and Native Americans together which showed no significant difference in prenatal testosterone levels (Martel and Roberts, 2014).

Umbilical cord and testosterone exposure

Ellis then talks about testosterone in the umbilical cord, and if the babe is exposed to higher levels of testosterone in vitro, then this should account for racial/ethnic differences in crime. However, the study he cited (Argus-Collins et al, 2012) showed no difference in testosterone in the umbilical cord while Rohrmann et al (2009) found no difference in testosterone between blacks and whites but found higher rates of SHBG (sex hormone-binding globulin) which binds to testosterone and makes it unable to leave the blood which largely makes testosterone unable to affect organ development. Thusly, if the finding of higher levels of SHBG in black babes is true, then they would be exposed to less androgenic hormones such as testosterone which, again, goes against the ENA theory.

He also cites two more studies showing that Asian babes have higher levels of umbilical cord testosterone than whites (Chinese babes were tested) (Lagiou et al, 2011; Troisi et al, 2008). This, again, goes against his theory as he rightly noted.

Circulating testosterone

Next he talks about circulating differences in testosterone between blacks and whites. He rightly notes that testosterone must be assayed in the morning within an hour after waking as that’s when levels will be highest, yet cites Ross et al (1986) where assay times were all over the place and thusly testosterone cannot be said to be higher in blacks and whites based on that study and should be discarded when talking about racial differences in testosterone due to assay time being between 10 am and 3 pm. He also cites his study on testosterone differences (Eliss and Nyborg, 1993), but, however, just as Ross et al (1986) did not have a control for WC (waist circumference) Ellis and Nyborg (1993) did not either, so just like the other study that gets cited to show that there is a racial difference in testosterone, they are pretty hugely flawed and should not be used in discussion when discussing racial differences in testosterone. Why do I not see these types of critiques for Ross et al (1986) in major papers? It troubles me…

He also seems to complain that Lopez et al (2013) controlled for physical activity (which increases testosterone) and percent body fat (which, at high levels, decreases testosterone). These variables, as I have noted, need to be controlled for. Testosterone varies and fluctuated by age; WC and BMI vary and fluctuate by age. So how does it make sense to control for one variable that has hormone levels fluctuate by age and not another? Ellis also cites studies showing that older East Asian men had higher levels of testosterone (Wu et al, 1995). Nevertheless, there is no consensus; some studies show Chinese babes have higher levels of testosterone than whites and some studies show that whites babes have higher levels of testosterone than Chinese babes. Indeed, this meta-analysis by Ethnicmuse shows that Asians have the highest levels, followed by Africans then Europeans, so this needs to be explained to save the theory that testosterone is the cause of black overrepresentation of violence (as well as what I showed that testosterone is important for vital functioning and is not the boogeyman the media makes it out to be).

Bone density and crime

Nevertheless, the next variable Ellis talks about is bone density and its relationship to crime. Some studies find that blacks are taller than whites while other show no difference. Whites are also substantially taller than Asian males. Blacks have greater bone density than the other three races, but according to Ellis, this measure has not been shown to have a relationship to crime as of yet.

Penis size, race and crime

Now on to penis size. In two articles, I have shown that there is no evidence for the assertion that blacks have larger penises than whites. However, states that penis length was associated with higher levels of testosterone in Egyptian babes. He states that self-reported penis size correlates with self-reports of violent delinquency (Ellis and Das, 2012). Ellis’ main citations for the claim that blacks have larger penises than other races comes from Nobile (1982), the Kinsey report, and Rushton and Boagert (1987) (see here for a critique of Rushton and Boagert, 1987), though he does cite a study stating that blacks had a longer penis than whites (blacks averaging 5.77 inches while whites averaged 5.53 inches). An HBDer may go “Ahah! Evidence for Rushton’s theory!”, yet they should note that the difference is not statistically significant; just because there is a small difference in one study also doesn’t mean anything for the totality of evidence on penis size and race—that there is no statistical difference!

He then cites Lynn’s (2013) paper which was based on an Internet survey and thus, self-reports are over-measured. He also cites Templer’s (2002) book Is Size Important?, which, of course, is on my list of books to read. Nevertheless, the ‘evidence’ that blacks average larger penises than whites is extremely dubious, it’s pretty conclusive that the races don’t differ in penis size. For further reading, read The Pseudoscience of Race Differences in Penis Sizeand read all of Ethnicmuses’ posts on penis size here. It’s conclusive that there is no statistical difference—if that—and any studies showing a difference are horribly flawed.

2d/4d ratio and race

Then he talks about 2d/4d ratio, which supposedly signifies higher levels of androgen exposure in vitro (Manning et al, 2008) however these results have been challenged and have not been replicated (Koehler, Simmons, and Rhodes, 2004; Yan et al, 2008, Medland et al, 2010). Even then, Ellis states that in a large analysis of 250,000 respondents, Asians had the lowest 2d/4d ratio, which if the hypothesis of in vitro hormones affecting digit length is to be believed, they have higher levels of testosterone than whites (the other samples had small ns, around 100).

Prostate-specific antigens, race, and prostate cancer

He then talks about PSA (prostate-specific antigen) rates between the races. Blacks are two times more likely to get prostate cancer, which has been blamed on testosterone. However, I’ve compiled good evidence that the difference comes down to the environment, i.e., diet. Even then, there is no evidence that testosterone causes prostate cancer as seen in two large meta-analyses (Stattin et al, 2003; Michaud, Billups, and Partin, 2015). Even then, rates of PCa (prostate cancer) are on the rise in East Asia (Kimura, 2012; Chen et al, 2015Zhu et al, 2015) which is due to the introduction of our Western diet. I will cover the increases in PCa rates in East Asia in a future article.

CAG repeats

He then reviews the evidence of CAG repeats. There is, however, no evidence that the number of CAG repeats influences sensitivity to testosterone. However, intra-racially, lower amounts of CAG repeats are associated with higher spermatozoa counts—but blacks don’t have higher levels of spermatozoa (Mendiola et al, 2011; Redmon et al, 2013). Blacks do have shorter CAG repeats, and this is consistent with the racial crime gap of blacks > whites > Asians. However, looking at the whole of the evidence, there is no good reason to assume that this has an effect on racial crime rates.

Intelligence and education

Next he talks about racial differences in intelligence and education, which have been well-established. Blacks did have higher rates of learning disabilities than whites who had higher levels of learning disabilities then Asians in a few studies, but other studies show whites and South Asians having different rates, for instance. He then talks about brain size and criminality, stating that the head size of males convicted for violent crimes did not differ from males who committed non-violent crimes (Ikaheimo et al, 2007). I won’t bore anyone with talking about what we know already: that the races differ in average brain size. However, a link between brain size and criminality—to the best of my knowledge—has yet to been discovered. IQ is implicated in crime, so I do assume that brain size is as well (no matter if the correlation is .24 or not; Pietschnig et al, 2015).

Prenatal androgen exposure

Now to wrap things up, the races don’t differ in prenatal androgen exposure, which is critical to the ENA theory; there is a small difference in the umbilical cord favoring blacks, and apparently, that predicts a high rate of crime. However, as noted, blacks have higher levels of SHBG at birth which inhibits the production of testosterone on the organs. Differences in post-pubertal testosterone are small/nonexistent and one should not talk about them when talking about differences in crime or disease acquisition such as PCa. DHT only shows a weak positive correlation with aggression—the same as testosterone (Christiansen and Winkler, 1992; however other studies show that DHT is negatively correlated with measures of physical aggression; Christiansen and Krussmann, 1987; further, DHT is not so evil after all).

Summing it all up

Blacks are not stronger than whites, indeed evidence from the races’ differing somatype, grip strength and leverages all have to do with muscular strength. Furthermore, the study that Ellis cites as ‘proof’ that blacks are stronger than whites is on one measure; an isokinetic dynamometry machine which is pretty much a leg extension. In true tests of strength, whites blow blacks away, which is seen in all major professional competitions all around the world. Blacks do have denser bones which is due to androgen production in vitro, but as of yet, there has been no research done into bone density and criminality.

The races don’t differ on penis size—and if they do it’s by tenths of an inch which is not statisitcally significant and I won’t waste my time addressing it. It seems that most HBDers will see a racial difference of .01 and say “SEE! Rushton’s Rule!” even when it’s just that, a small non-significant difference in said variable. That’s something I’ve encountered a lot in the past and it’s, frankly, a waste of time to converse about things that are not statistically significant. I’ve also rebutted the theory on 2d/4d ration as well. Finally, Asians had a similar level of androgen levels compared to blacks, with whites having the least amount. Along with a hole in the theory for racial differences in androgen causing crime, it’s yet another hole in the theory for racial differences in androgens causing racial differences in penis size and prostate cancer.

On intelligence scores, no one denies that blacks have scored about 1 SD lower than whites for 100 years, no one denies that blacks have a lower educational attainment. In regards to learning disabilities, blacks seem to have the highest rates, followed by Native Americans, than non-Hispanic whites, East Asians and the lowest rates found in South Asians. He states only one study links brain size to criminal behavior and it showed a significant inverse relationship with crime but not other types of offenses.

This is a really good article and I like the theory, but it’s full of huge holes. Most of the variables described by Ellis have been shown to not vary at all or much between the races (re: penis size, testosterone, strength [whites are stronger] prostate cancer caused mainly by diet, 2d/4d ratio [no evidence of it showing a digit ratio difference], and bone density not being studied). Nevertheless, a few of his statements do await testing so I await future studies on the matter. He says that androgen exposure ‘differs by race and ethnicity’, yet the totality of evidence shows ‘not really’ so that cannot be the cause of higher amounts of crime. Ellis talks about a lot of correlates with testosterone, but they do not pass the smell test. Most of it has been rebutted. In fact, one of the central tenets of the ENA theory is that the races should differ in 2d/4d ratio due to exposure of differing levels of the hormone in vitro. Alas, the evidence to date has not shown this—it has in fact shown the opposite.

ENA theory is good in thought, but it really leaves a lot to be desired in regards to explaining racial differences in crime. More research needs to be looked into in regards to intelligence and education and its effect on crime. We can say that low IQ people are more likely to drop out of school and that is why education is related to crime. However, in Mazur (2016) shows that blacks matched for age had lower levels of testosterone if they had some college under their belt. This seems to point in the direction of the ENA theory, however then all of the above problems with the theory still need to be explained away—and they can’t! Furthermore, one of the nails in the coffin should be this: East Asian males are found to have higher levels of testosterone than white males, often enough, and East Asian males actually have the lowest rate of crime in the worle!

This seems to point in the direction of the ENA theory, however then all of the above problems with the theory still need to be explained away—and they can’t! Furthermore, one of the nails in the coffin should be this: East Asian males are found to have higher levels of testosterone than white males, often enough, and East Asian males actually have some of the lowest rate of crime in the world (Rushton, 1995)! So this is something that needs to be explained if it is to be shown that testosterone facilitates aggression and therefore, crime.

Conclusion

I’ve shown—extensively—that there is a low positive correlation between testosterone and physical aggression, why testosterone does not cause crime, and have definitively shown that, by showing how flawed the other studies are that purport to show blacks have higher testosterone levels than whites, along with citing large-scale meta-analyses, that whites and blacks either do not differ or the differences is small to explain any so-called differences in disease acquisition or crime. One final statement on the CAG repeats, they are effect by obesity, men who had shorter CAG repeats were more likely to be overweight, which would skew readings (Gustafsen, Wen, and Koppanati, 2003). So depending on the study—and in most of the studies I cite whites have a higher BMI than blacks—BMI and WC should be controlled for due to the depression of testosterone.

It’s pretty conclusive that testosterone itself does not cause crime. Most of the examples cited by Ellis have been definitively refuted, and his other claims lack evidence at the moment. Even then, his theory rests on the 2d/4d ratio and how blacks may have a lower 2d/4d ratio than whites. However, I’ve shown that there is no significant relationship between 2d/4d ratio and traits mediated by testosterone (Kohler, Simmons, and Rhodes, 2004) so that should be enough to put the theory to bed for good.

Why Testosterone Does Not Cause Crime

Edit: (The correlation between aggression and testosterone isn’t .14 as Book et al (2001) state; the true correlation is .08 (Archer, Graham-Kevan and Davies, 2005) So it’s even lower than I thought. This is one of the many reasons why testosterone does not cause crime. It’s just feminist bullshit and fear mongering from people who do not understand the hormone and what it does in the body. The misconceptions come from Rushton’s r/K selection bullshit which has been summarily refuted.)

Recently, I’ve written at length on racial differences in testosterone and how the correlation between testosterone and physical aggression is .14. Pitifully low to account for the cause of crime and any overall differences in racial crime (that will be touched on at length in the future). Tonight I will show, yet again, why testosterone does not cause crime by looking at what times most crimes are committed by both adults and children under the age of 18. This will definitively put the ‘testosterone causes crime’ myth to bed for good.

Before I get into the time of day that most crimes are committed, I must talk about the production of testosterone in the body. There are no ‘genes for’ testosterone (although men who had three certain alleles had a 6.5 fold higher risk of having low testosterone; Ohlsson et al, 2011, I am unaware of there being a variation by race; over 10,000 Caucasian men were studied). There is, however, an indirect control of testosterone synthesis by DNA. DNA regulates the production of testosterone by coding for enzymes that convert cholesterol to testosterone (testosterone is a cholesterol-based hormone).

There are five simple steps to the production of testosterone: 1) DNA codes for mRNA; 2) mRNA codes for the synthesis of an enzyme in the cytoplasm; 3) luteinizing hormone stimulates the production of another messenger in the cell when testosterone is needed; 4) this second messenger activates the enzyme; 5) the enzyme then converts cholesterol to testosterone (Leydig cells produce testosterone in the presence of luteinizing hormone). That’s how testosterone is produced in the body. It is indirectly controlled by DNA.

Above is a graph from the Office of Juvenile Justice and Delinquency Prevention which shows the time of day that most crimes are committed. Notice how crime goes up as the time of day goes on and since kids are at school, they’re more likely to fight. This then peaks at 3 pm when kids are getting out of school.

Now look at rates of crime for adults. At its peak of 10 pm, it’s vastly lower than that of people under the age of 18, which is important to keep in mind. You can see how at 8 am that rates of crime are low for adults and high for kids, right when they would be entering school so there would be a lot of other kids around and the chance for violence goes up. Keep the times of 8 am (kids when they enter school), 12 pm (when most kids go on lunch) and 3 pm (when most kids get out of school) along with the hours of 12 pm to 8 pm for adults (when 74 percent of crimes are committed by adults).

The OJJDP writes:

  • In general, the number of violent crimes committed by adults increases hourly from 6 a.m. through the afternoon and evening hours, peaks at 10 p.m., and then drops to a low point at 6 a.m. In contrast, violent crimes by juveniles peak in the afternoon between 3 p.m. and 4 p.m., the hour at the end of the school day.
  • Nearly one-third (29%) of all violent crime committed by juvenile offenders occurs between 3 p.m. and 7 p.m. In comparison, 26% of all violent committed by adult offenders occurs between 8 p.m. and 12 p.m.

So since testosterone varies by day and levels are highest at 8 am and lowest at 8 pm (Brambilla et al, 2009; however testing men aged 45 years of age and older is fine before 2 pm due to a blunted circadian rhythm; Long, Nguyen, and Stevermer, 2015), then how could testosterone account for why men commit most of their crimes at night and why the crime that children commit spikes when they go to school, go to lunch and get out of school? The answer is that it doesn’t because testosterone does not cause crime. What testosterone does cause, however, are feelings of confidence and dominance, which does not—surprisingly—lead to increased aggression and assault on others (Booth et al, 2006).

What testosterone does cause, however, is social dominance and success, not physical aggression and maladjustment (Shcaal et al, 1996). The effects of environment are also more notable on testosterone than are genetics at 5 months of age (Carmaschi et al, 2010). Furthermore, aggressive behavior is first noticed in infancy and reaches its peak before school age (Tremblay et al, 2004; Cote et al, 2006). Though testosterone does seem to have an effect on aggression in preschool boys, however genetic and environmental causality has not been established (Sanchez-Martin et al, 2000).

Nevertheless, the meta-analyses I cited last week show that testosterone has an extremely low correlation of .14, so other factors must be at play. However, Sanchez-Martin et al (2000:778-779) also note that “Tremblay et al (1998) suggested that associations between testosterone titer and physical aggression are likely to be observed in contexts where such attack leads to social dominance. This may be true of the preschool boys in the present study. The data generated in the present study generally support Scerbo and Kolko (1994), who studied older children (7 to 14 years of age). They found a significant relationship between testosterone levels and aggression (as assessed by clinical staff).

It’s interesting to note that in the case of Scerbo and Kolko (1994) that after controlling for age and size, testosterone correlated with aggression when rated by staff but not parents or teachers. ‘Staff’ refers to clinic staff at a facility where the children were assessed for hyperactivity disorders. Of course, the staff would rate higher levels of aggression compared to parents of teachers—people who are around the children every day—since they would want a higher chance for diagnosis for certain drugs to ‘cure’ the hyperactivity, but I digress. Testosterone does not induce aggression in children, but it does induce social dominance and confidence which does not lead to aggression (Rowe et al, 2004; Booth et al, 2006).

There was also little difference in testosterone between socially dominant prisoners and aggressive prisoners (Ehrenkraz, Bliss, and Sheard, 1974). Furthermore, the testosterone increase leading to pubertal development in boys is not associated with increased aggression (Tremblay et al, 1998; Booth et al, 2006: 171). Indeed, increased body size is a marker for physical aggression in children, and I doubt these children have high muscle mass so, I assume, they have high levels of body fat and thusly lower levels of testosterone than they would have if they were leaner. Yet another strike against the ‘testosterone causes crime/physical aggression’ hypothesis.

Indeed, this has some implications for the honor culture hypothesis of why low-income blacks have higher levels of testosterone than similarly aged blacks with some college (Mazur, 2016). The patterns for crime as shown by the OOJDP shows that crime rises as the day progresses from the morning until its peak at 3 pm for children and then sharply declines while for adults it peaks at 10 pm.

Testosterone does increase when a challenge is issued; when one man feels his reputation is threatened, the propensity for violence is increased, but this was most notably seen in Southern men (Cohen et al, 1996). So the same would be said for this ‘culture of honor’ found in low-income black neighborhoods, the so-called ‘code of the street’ as stated by Anderson (1994: 88): “Moreover, if a person is assaulted, it is important, not only in the eyes of his opponent but in the eyes of his “running buddies,” for him to avenge himself. Otherwise, he risks being “tried” (challenged) or “moved on” by any number of others. To maintain his honor, he must show he is not someone to be “messed with” or “dissed.”

This culture of honor is found all over the world, including Brazil where homicide can be explained by the need to maintain honor and can be understood by taking into account cultural factors; biological, psychological and socioeconomic factors do not explain murder in Northeast Brazil as well as honor and culture (de Souza et al, 2015). People in honor cultures also have a higher chance of self-harm (Osterman and Brown, 2011) as well as a higher chance of committing violence in school (Brown, Osterman, and Barnes, 2009).

Testosterone does not cause crime; it does not cause aggression. Increases in testosterone before, during and after events are a physiologic process to prime the body for competition. As cited above, dominant behavior does not necessarily lead to violence in most cases, which may be surprising for some. Indeed, honor and culture may explain a nice amount of the homicide and violence rate in the South. Since testosterone is highest at 8 am and lowest at 8 pm and the rates of crime committed by adults and children are vastly different than the diurnal variance in the day, then testosterone does not cause crime and its increase is not associated with crime, but social dominance and confidence which does not lead to crime.

Hopefully—if anyone still believes testosterone to be the boogeyman its made out to be—I’ve put those misconceptions to rest. Racial differences in testosterone cannot be the cause of racial differences in crime—because there is either no statistical difference in testosterone between the races or the difference is non-existent. Testosterone is clearly a beneficial hormone—as I have extensively documented. Misunderstandings of the hormone are abound—especially in the HBD sphere—only due to literally a few paragraphs in a book (Rushton, 1997) and one study that showed blacks have higher testosterone than whites which was the cause of their higher rates of prostate cancer (Ross et al, 1986). The study is hard to find so I had to buy access to it. I will cover this in the future, but I discovered that they assayed the subjects when it was convenient for them—between the hours of 10 am and 3 pm—which is unacceptable. You cannot gauge racial differences in testosterone from a small study (n=50) and a non-representative sample (college students). For these reasons, the study should be thrown in the trash—especially when formulating evolutionary hypotheses.

Testosterone is one of the most important hormones for vital functioning. By knowing how it is processed in the body and that there are no ‘genes for’ testosterone (‘low testosterone genes’ notwithstanding) along with how testosterone has a low relationship with physical aggression one should not be scared of having high levels, on the contrary, one should be scared of having low levels. I have once again proven my case that testosterone is not related to violence in showing the diurnal variation in testosterone levels in adults, as well as the time of day that crimes are committed by both adults and children. High testosterone means high confidence and high dominance—and those two traits have a lot to do with masculinity—which do not lead to violence.

I know why testosterone does not cause crime—because I have an understanding of the hormone, how its produced in the body and what its effects on the body are. The most important thing to note here, is that even if blacks had 15 percent higher testosterone than whites, it still wouldn’t explain higher rates of crime or disease such as prostate cancer. So those who try so hard to prove that blacks have higher levels of the hormone do so in vain, because even if they did it wouldn’t mean anything for any theories they may have. The myth of testosterone causing aggression and crime need to be put to bed for good.

The Evolution of Violence: A Look at Infanticide and Rape

1700 words

The pioneer of criminology was a man named Cesare Lombroso, an Italian Jew (a leftover remnant from the Roman days), who had two central theories: 1) that criminal behavior originated in the brain and 2) criminals were an evolutionary throwback, a more primitive type of human. Lombroso felt strongly about the rehabilitation of criminals, at the same time believing in the death penalty for “born criminals”. Though, with new advances in criminology and new insights to the brain, it looks like Lombroso was right with his theory of born criminals.

Why are you 100 times more likely to be killed on your birthday? Why are children 50 times more likely to be murdered by their stepfather than biological one? Why do some parents kill their children? Finally, why do men rape not only strangers, but also rape their wives? All of these questions can be answered with evolutionary psychology.

Evolutionarily speaking, antisocial and violent behavior wasn’t a random occurrence. When these actions occurred tens of thousands of years ago, they were because resources were being acquired from these actions. Thus, we can see some modern criminal acts as resource competition. The more resources one has, the easier it is for him to pass his genes on to the next generation (a big driver for violence). In turn, women are more attracted to males who can provide resources and protection (those who were more antisocial and violent). This also explains these prison romances, in which women get into romances with murderous criminals since they are attracted to the violence (protection) and resources (theft).

The mugger who robs for a small amount of money is increasing his odds of resource acquisition. Drive-by shootings in violent neighborhoods increase the status of those who survive the shootout. What looks like a simple brawl over nothing may be one attempting to increase social dominance. All of these actions have evolutionary causes. What drive these actions are our ‘Selfish Genes’.

The more successful genes are more ruthlessly selfish in their struggle for survival, which then drives individual behavior. The individual behaviors that occur due to our selfish genes may be antisocial and violent in nature, which in our modern society is frowned upon. The name of the game is ‘fitness’. The amount of children you can have in your time allotted on Earth. This is all that matters to our genes. Even those accomplishments you think of, such as completing college or attaining mass amounts of capital all fall back to fitness. With that, increasing your fitness and ensuring your genetic lineage passes on to the next generation is greatly enhanced.

Biological fitness can be enhanced in one of two ways. You can have as many children as possible, giving little parental care to each, or you can have fewer children but show more attention and care to them. This is known as r/K Selection Theory. Rushton’s r/K Selection Theory compliments Dawkins Selfish Gene theory in that the r-strategist is maximizing his fitness by having as many children as possible, while the K-strategist increases his fitness by having fewer children in comparison to the r-strategist but showing more parental attention. There are, however, instances in which humans kill children, whether it’s a mother killing a newborn baby or a stepfather killing a child. What are the reasons for this?

Killing Kids

The risk of being a homicide victim in the first year of life is highest in the first year of life. Why? Canadian Psychologists Daly and Wilson demonstrated in inverse relationship between degree of genetic relatedness and being a victim of homicide. Daly and Wilson discovered that the offender and victim are genetically related in only 1.8 percent of all homicides. Therefore, 98 percent of all murders are killings of people who do not share the killer’s genes.

Many stories have been told about ‘wicked stepparents’ in numerous myths and fairytales. But, as we know, a lot of stories have some basis in reality. Children of stepparents are 40 times more likely to suffer abuse at the hands of a stepparent. People who are living together who are unrelated to one another are more likely to kill one another. Even adoptions are more successful when the adopting parents view the child as genetically similar to themselves.

In this study carried out by Maillart, et al, it was discovered that for mothers, the average age of offense for filicide was 29.5 years for the mother and 3.5 years for the babe. Bourget, Grace, and Whitehurst, 2007 showed that a risk factor for infanticide was a second child born to a mother under 20-years of age. The reasoning for this is simple: at a younger age the mother is more fertile, and thus, more attractive to potential mates. The older the woman is the more sense it makes to hold on to the genetic investment since it’s harder to make up for the genetic loss late in her reproductive life.

Genetic relatedness, fitness, and parental investment show, in part, why filicides and infanticides occur.

Raping Your Wife

There are evolutionary reasons for rape as well. The rape of a non-relative can be looked at as the ultimate form of ‘cheating’ in this selfish game of life. One who rapes doesn’t have to acquire resources in order to attract a mate, he can just go and ‘take what he wants’ and attempt to spread his genes to the next generation through non-consensual sex. It’s known that rape victims have a higher chance of getting pregnant, with 7.98 percent of rape victims becoming pregnant. (News article) One explanation for this is that the rapist may be able to possibly detect how fertile a woman is. Moreover, rapists are more likely to rape fertile women rather than infertile women.

One rapist that author of the book The Anatomy of Violence, Adrian Raine interviewed said that he specifically chose ugly women to rape (Raine, 2013: 28). He says that he’s giving ugly women ‘what they want’, which is sex. There is a belief that women actually enjoy sex, and even orgasm during the rape, even though they strongly resist and fight back during the attack. Reports of orgasm during rape are around 5 to 6 percent (Raine, 2013: 29), but the true number may be higher since most women are embarrassed to say that they orgasmed during a rape.

Men, as we all know, are more likely to engage in no-strings-attached sex more than women. This is due to the ‘burden’ of sex: children. Women are more likely to carefully select a partner who has numerous resources and the ability to protect the family. Men don’t have the burden of sticking around to raise the child.

Men are more likely to find a sexual relationship more upsetting in comparison to women who are more likely to find an emotional infidelity as more distressing. This data on Americans still held true for South Korea, Germany, Japan, and the Netherlands. Men are better than women at detecting infidelity, and are more likely to suspect cheating in their spouses (Raine, 2013: 32). Unconscious reason being, a man doesn’t want to raise a child who is not genetically similar to themselves.

But this begs another question: why would a man rape his wife? One reason is that when a man discovers his spouse has been unfaithful, he would want to inseminate her as quickly as possible.

There has never in the history of humankind been one example of women banding together to wage war on another society to gain territory, resources or power. Think about it. It is always men. There are about nine male murderers for every one female murderer. When it comes to same-sex homicides, data from twenty studies show that 97 percent of the perpetrators are male. Men are murderers. The simple evolutionary reason is that women are worth fighting for. (Raine, 2013: 32)

A feminist may look at this stat and say “MEN cause all of the violence, MEN hurt women” and attempt to use this data as ‘proof’ that men are violent. Yes, we men are violent, and there is an evolutionary basis for it. However, what feminists who push the ‘all sexes are equal’ card don’t know, is that when they say ‘men are more likely to be murderers’ (which is true), they are actively accepting biological differences between men and women. Most of these differences in crime come down to testosterone. I would also assume that men would be more likely to have the ‘warrior gene’, otherwise known as the MAOA-L gene, which ups the propensity for violence.

The sociobiological model suggests that poorer people kill due to lack of resources. And one reason that men are way more likely to be victims of homicide is because men are in competition with other men for resources.

Going back to the violence on stepchildren that I alluded to earlier, aggression towards stepchildren can be seen as a strategic way of motivating unwanted, genetically dissimilar others out of the home and not take up precious resources for the next generation bred by the stepfather (Raine, 2013: 34).

Women also have a way to increase their fitness, which a brunt of it is through sexual selection. Women are known to be ‘worriers’. That is, they rate dangerous and aggressive acts higher than men. Women are also more fearful of bodily injury and more likely to develop phobias of animals. In these situations, women are protecting themselves and their unborn (or born) children by maximizing their chances for survival by being more fearful of things. This can help explain why women are less physically violent than men and why those murder stats are so heavily skewed towards men: biology.

Women compete for their genetic interests with beauty and childbearing. The more beautiful the woman, the better resources a woman can acquire from a male and this will ensure a healthy life for the offspring.

Evolutionary psychology can help explain the differences in murder between men and women. It can also explain why young mothers kill their children and why stepparents are so abusive to, and are more likely to murder stepchildren. Of course, a social context is involved but we need to look at evolutionary causes for what we think we may be able to simply explain. Because it’s, more often than not, more complex than we could imagine. And that complexity is our Selfish Genes doing anything possible to reproduce more copies of itself through its vehicle: the human body.

Climate, Violence, r/K Selection Theory and the Vindication of JP Rushton

1850 words

Why do violent crimes increase as temperatures increase? Why do violent crimes decrease as the temperatures decrease? These phenomena are noticed every year, and criminologists set out to find the relationship between climate and violence and whether or not there is a curvilinear hypothesis, which crime increases as the temperature increases, but at extremely high temperatures the crime rate begins to dip down.

When the weather gets colder, crime decreases. All though crime does decrease in the Winter months, crimes that take more planning, such as property crime and robbery increase. This is due, obviously, to the fact that people don’t want to spend too much time outside so they plan their crimes ahead to minimize the time spent outside whereas in hotter temperatures this does not occur. It is known that when it’s colder, resulting criminal actions are less random than those committed in hotter temperatures.

The two trains of thought for the temperature/crime theory are the curvilinear hypothesis, as noted above, and the linear hypothesis, which argues for that as the temperature increases, so does crime without a drop in extremely high temperatures.

Mishra (2014) showed that the relationship is not a curvilinear one, but that crime rises steadily as the temperature increases. Looking at Allahabad city, India from a 62 year period from the years 1952 to 2013 with the variables being temperature, humidity and rainfall, the results of the analysis shows that temperature has a significant effect on the proclivity to commit crime, as well as murder. Relative to the temperature, humidity shows a strong correlation with crime with rainfall showing a negative correlation.

Mishra took annual data from the National Crime Record Bureau with monthly data taken from the various police stations of Allahabad city. The temperature and rainfall data was taken from local news stations and the Indian Meteorological Department.

Results of his analysis showed significant correlations with violent crime and temperature (r=.75) with murders increasing as temperatures increase. The relationship between relative humidity and crime was strong as well (r=.68) with rainfall having a negative correlation (r=-.14). Out of all three of these variables, the average temperature has more of an effect on crime than relative humidity. Using a regression model, Mishra discovered a correlation of .56, showing that temperature alone accounts for 56 percent of the variation in crime pattern. Including all three variables in the regression model shows a correlation of .61. This confirms that among the climate elements tested that temperature itself had the highest effect on crime.

Figure 2 of the paper shows that as temperatures rise (starting at about 25 degrees celsius), that the crime rate increases.Since very high temperatures are associated with rainfall, there is a reduction in crime when this occurs, thermal stress is reduced. However, when rainfall and humidity were both unchanged, higher temperatures would not cause a decrease in violence. This result is inconsistent with the curvilinear hypothesis and does not support the claim that extremely high temperatures cause decreased violence.

Van Lange, Rinderu, and Bushmen (2016) thought of the model CLASH (CLimate, Aggression, and Self-control in Humans) which shows differences within and between countries and their proclivities for aggression and criminal behavior. With lower temperatures, along with seasonal variation like what is seen in Northern Europe, peoples had to adopt a slower life history strategy with more focus on planning for the future as well as a need for self-control due to the differing variations in climate and how that has an effect on acquiring food. The CLASH model further shows that slow life history strategy, thinking into the future and self-control are important determinants in predicting violence.

As I have discussed here before, r/K Selection Theory (Life History Theory) shows that those who live in colder temperatures adopt slower strategies which lead to more future planning along with more self-control along with more altruistic behaviors shown. In a more harsh environment, such as Africa, Latin America and other locations situated near the equator, faster life history strategies are needed to offset the harsh environment, which leads to evolutionary causes for earlier menarche in black and Mexican-American girls. Faster life history strategies are needed in locations near the equator due to the harshness of the environment. This is why Africans and other peoples located at or near the equator have more children, to offset the harsher environment. No planning ahead was needed, as most likely populations near the equator wouldn’t have lived long enough to see the delayed payoff. Conversely, those in northerly climes live longer due to the need to plan ahead,  and along with this ability to plan ahead came higher intelligence, which leads to yet another selector for high intellect in populations that evolved further from the equator, earlier childbirth. On top of that selector, deleterious Neanderthal alleles decreased historic fitness levels 1 percent in non-African populations, which further lead to evolution of the ability to think into the future due to less children beared. Since the future becomes more predictable the further you travel away from the equator, it becomes adaptive for peoples to adopt a slower life history strategy out of necessity, as that’s the only way to survive and they will see the fruits of their self-control due to having a longer life expectancy due to superior future time orientation in comparison to those in southerly climes.

Since a faster life history strategy is correlated with threats of harshness and higher morbidity and mortality, from the life history perspective we would reason that those with lower SES would have to adopt a faster life history strategy in order to offset the fact that they are more likely to suffer premature disability or death. Lower SES is also correlated with other r-selected strategies such as earlier sexual activity (a variable correlated with lower IQ), higher rates of childhood pregnancy and childbearing, greater number of offspring and less care and attention shown to those offspring, this study. For the third time this month, proves Rushton right with his application of r/K Selection Theory on the three races of humanity.

Van Lange, Rinderu, and Bushmen state that neighborhood deterioration, assaults, muggings, drug addicts, and presence of gangs are associated with earlier and higher rates of sexual activity. Not coincidentally, this is seen in many majority black and ‘Hispanic’-majority cities in America. They also say that as resources become scarce that women gravitate towards men with more access to resources and those that will invest in their children’s reproductive values. Though this is hardly seen in low-income communities around America, you do see a lot of black women who gravitate towards the drug dealer or another black male who is involved with illegal activities who then acquire mass amounts of capital. This is an evolutionary strategy for all women, since money is correlated with intelligence and therefore a mate with more money has better means to take care of any offspring conceived.

The CLASH model extends r/K Selection Theory, particularly where r/K Selection Theory emphasizes unpredictability and harshness as a source of environmental stress, the CLASH model emphasizes predictability over environmental stress. That is, those who evolved in northerly climes can deal with stress better than those who evolved near the equator, therefore lessening the amount of crime in those populations due to them being able to constrain themselves more. The CLASH model proposes that the combination of predictability and control shape a slow life history strategy, future time orientation, with a focus on self-control. Moreover, in an analysis of 40 work-related values in 40 countries, it was found that the countries located the furthest from the equator tended to place a greater value on future rewards, such as perseverance and thrift.

In countries closer to the equator, according to the 2014 World Fact Book, the average age of first birth for a female was 20 years of age (the countries were the Gaza strip, Liberia, Bangladesh, Kenya, Mali, Tanzania, Uganda and  various other middle African countries). Conversely, for countries further away from the equator, the average age of first birth was 28 years of age (Japan, Canada, and most European countries). Those populations that evolved in warmer climates where the changes in season are minimal with unpredictable harshness tend to enact faster life history strategies than those in colder climates.

The researchers state on page 31:

One standard deviation increase in temperature was associated with a 11.3% increase in intergroup conflict and a 2.1% increase in interpersonal conflict. Examples of interpersonal conflict include spikes in domestic violence in India and Australia, greater likelihood of assaults and murders in the USA and Tanzania, ethnic violence in Europe and South Asia, and civil conflicts throughout tropical climates. Hence, we conclude that it is both differences in average temperature and differences in seasonal variation in temperature that help explain cross-national differences in aggression and violence around the world.

And on page 41:

Assuming CLASH is accurate, it is interesting to consider that people’s thoughts and behaviors may be quite different, based on the physical circumstances their ancestors faced and that they face themselves. The world is getting smaller and smaller. Electronic and social media (e.g., WhatsApp, Twitter, Facebook, email) connect us to people all over the world. Yet, people coming from differing ancestral histories and living in different locations face challenges of self-control in a variety of ways. A businessperson from London may expect a response the next day, but the alliance in Nairobi may want to take at least an extra day. If CLASH is correct, the same pattern should hold for within-country differences between a businessperson working in Chicago and the alliance working in New Orleans, or between a businessperson working in Melbourne and the alliance in Brisbane or Cairns (with London, Chicago, and Melbourne being relatively more remote from the equator, and facing greater variation in climate).

The correlation between temperature, crime and life history strategies is shockingly high. JP Rushton is now vindicated from all of the derision he experienced in the 30 plus years he was pushing his r/K Theory. This shows implications for the European ‘refugee’ crisis as well, due to the higher rates of all violent crime occurring ever since this mass exodus from MENA (Middle Eastern North African) countries.

The CLASH model is a great compliment to r/K Selection Theory and goes deeper into why behaviors differ in human populations based where ancestral evolution occurred. As temperatures increase, so does crime starting at 76 degrees Fahrenheit, with there being a negative correlation for crime committed during rainfall. The CLASH model vindicates Rushton’s supposedly ‘wacky theories’ on race, evolution and behavior. Further, the CLASH model also shows another cause for the current situation occurring in Europe. The people flooding into the continent have ancestral ties to hotter climes. They then bring their genetic proclivity to commit crimes with them to the new area, which then increases crime. This is one of many  reasons for the cucking of Europe. As we look more into evolutionary causes for behavior and those behaviors that lead to more crime committed, Rushton and others will be further vindicated and when this occurs, with ample data, of course, sensible immigration policy can be had to quell the amount of crime committed by ‘migrants’ and other immigrants into our countries.

Blacks Are Less Violent Than Whites?

I’ve read a lot of crazy things in my life, though this must be the craziest. Someone really believes that “blacks are less violent than whites“. To believe such a claim, you would have to close your eyes to all of the relevant data. From naming outright falsities to obscuring data to fit his narritive, this article will show and refute a distorted reality, one that the Left wishes to show, to one simply looking for the truth to interracial crime.

This is not unique to Europeans. The Rwandan Genocide (which was due to ethnocentrism) and the ethnic cleansing currently occurring in Central Africa aren’t real? Fact of the matter is, is that every ethnicity has participated in ‘ethnic cleansing’, which is really just protecting genetic interests. This is a non-factor as this has gone on before European colonialism.

colonization of Africa and the Caribbean

Colonialism was good for the native inhabitants of Africa. Speaking of the Caribbean, how well did it end for the Haitians after they defeated Napolean?

American slavery

Oh? You mean how a majority of the slaveholders were Sephardic Jews? Or how there are reports from New Orleans from their 1860 census that showed 3000 freed blacks owned slaves, accounting for 28 percent of the city’s population? In 1860 Louisiana, at least 6 blacks owned more than 65 slaves, with the biggest number of slaves being 165 slaves who worked on a sugar plantation. How about the Jews’ role in American slavery? Moreover, at the height of slavery, a paltry 6 percent of Southern whites owned slaves, when combined with the North it was 1.4 percent. An estimated 3000 blacks had about 20000 slaves in 1860. But tall is only about the whites who did slavery, and not about the Arabs and how they started enslaving Africans FIRST, in 650 AD.

Native American Genocide

The Alternative Hypothesis just had a post the other day about the non-genocide of American Indians. Basically, their population was anywhere between 1.5 and 2 million people. Population reduction for the Native Americans was only 0.22 percent!! Doesn’t seem like such a ‘genocide’ to me. If so, that’s the slowest genocide I’ve ever heard of.

Jim Crow

People segregate naturally. We’re more segregated now than we were 50 years ago! Must be those residual effects from Jim Crow huh?

But somehow in the media it’s the black man who is portrayed as the savage.

I wonder why??

It’s just not fair. We white folks are so much better at race-based aggression than our darker complected brothers.

More intelligent than them, that’s why.

Just this Wednesday a white guy walked into a historic African American Church in South Carolina, was accepted as part of the service, stayed for about an hour before shouting a spiteful message and gunning down several parishioners!

Now that’s some hate right there!

One person does something and that means….what exactly?  It shows one person is hateful! Look at averages, not singular events.

Whenever anyone brings up race and violence, the first thing people mention is crime.

Because they are linked to each other. Why wouldn’t the two things be mentioned in the same breath?

There is more black-on-black crime than white-on-black crime, they say. And they’re correct!

According to a 2013 FBI Uniform Crime Report, when it comes to murder, 90 percent of black victims were killed by black offenders.

However, what people fail to mention is that according to the very same report, 83 percent of white victims were killed by white offenders, too.

These numbers don’t show black people are more violent than white people. They show that BOTH white and black people would rather kill within their own race.

Yea they show that both would rather kill within race, however you miss something very important here:  Interracial crime!

First, we find that during the 2012/2013 period, blacks committed an average of 560,600 violent crimes against whites, whereas whites committed only 99,403 such crimes against blacks. This means blacks were the attackers in 84.9 percent of the violent crimes involving blacks and whites. This figure is consistent with reports from 2008, the last year DOJ released similar statistics. Perhaps not coincidentally, that was the year Mr. Obama was elected president.


In terms of raw numbers, black people and white people actually commit about the same number of murders. But you wouldn’t know that from the media.

Not really. Per capita rates are more important than raw numbers, luckily we have data on that!

As of 2008, young black men kill at a rate of 7 times higher than white men.

Homicide Trends in the United States, 1980-2008 Annual Rates for 2009 and 2010 pg 11

Is that the same number of murders?? I’m looking at the same stat in a completely different way than you are.

The FBI is charged under the Hate Crime Statistics Act with compiling statistics on spite-based legal transgressions. In its most recent report, for 2013, hate crimes based on race are far more numerous than any other kind.

  1. The FBI is biased towards blacks and ‘hate crimes’. How about all of the countless times we here about blacks attacking whites using racial epithets during the attack? Too many to count. They are, however, not counted as hate crimes by the FBI because it doesn’t fit their narritive.
  2. I wonder how those numbers would look if actual hate crimes were included in this data (black on white included).

According to the FBI statistics, 54.5 percent of the reported single-bias hate crimes that were racially motivated in 2013 targeted blacks. Only 16.3% target whites.

Want to talk bias? The amount of black on white hate crimes that are NOT categorized as such. This skews the statistics considerably.

Would our economy really have been so robust without the free labor of all those slaves?

Yes. Whites could have done it, but getting blacks to do it was cheaper and more efficient. Using brains to get ahead is what life is all about. Whites build great societies anywhere. Our economy would have been as robust as it is now without America never having a history of slavery.

Heck! Would we even have a country at all if we hadn’t murdered all those indigenous peoples in the first place?

Is a population decline of 0.22 percent per year ‘murdering all those indigenous peoples’?

So let’s put it to rest. When it comes to hate crimes, white folks kill! But don’t feel too bad, black folks. There are things you’re good at, too. Like nonviolent resistance.

This guy is delusional. Just because MLK preached non-violence doesn’t mean that blacks as a whole are non-violent. Look at crime stats from anywhere in the world.

After all this time, black people have very rarely used violence as a means to achieve their ends, to try to secure the rights and freedoms white America guards so jealously.

Is this guy living in the same America as I am?

In just the past year or so, unarmed black folks have been assaulted or killed for holding toy guns

Go ahead and pick out the real one, then do it from a distance when you get a phone call that there is a kid walking around while waving a gun.

being suspected of selling loose cigarettes

He died due to asthma, obesity, and heart disease, that’s why he couldn’t breathe; he was 350 pounds. He also did not comply with the officers’ orders, which is why he needed to be taken down in such a fashion.

listening to music at a gas station

Dunn did say that Davis said he was going to kill him with a shotgun and that’s when he grabbed his gun out of his glove box.

asking for help after a car accident

Freak accidents happen that get blown up? Damn, that proves whites are more violent huh!?!?

wearing hoodies

Yea, people still believe that Trayvon got killed for ‘wearing a hoody’. We have jurys for a reason. We have trials for a reason. We have laws like Stand Your Ground for a reason. Trayvon was killed because if Zimmerman hadn’t of protected his life, he would be dead. All of these people complaining about the verdict, if you were put into that same situation, would you allow yourself to be killed for fear of being called ‘racist’?

wearing bikinis

Listen to police when they tell you to do something. Especially during an investigation. This shouldn’t even need to be said.

running

1) The Baltimore Six are going to get off for it. They caused no harm. 2) He threw himself around in the back of the van causing his own death.

and now just going to church!

Right. They were killed just for going to Church. eyeroll

And the response from the black community has been pretty darn nonviolent. Yeah there’s been some shouting and looting, but very little beating or killing.

‘Pretty darn non-violent. Which is why immediately after, blacks began false flagging Church burnings in an attempt to pin them on whites. So ‘peaceful’, right?

White folks, can you imagine having to undergo such indignity on a daily basis and NOT responding in kind!?

Can’t tell if serious. Just recently, a beta Trump supporter was thrown down on the ground by a ‘young black male’ and did not retaliate.

No wonder a blonde white girl from a Christian fundamentalist home darkened her skin, curled her hair and tried to pass as black! Sometimes – often really – it’s darn embarrassing to be white! Black folks have the moral high ground.

Because Dolezal is a moron.  Blacks have the moral high ground? Please show me where this occurs.

Somehow they live in an American society that heaps hatred on their every move and they respond with dignity and perseverance.

There’s no reason at all for this right? Just good old fashioned ‘racism’?

So why are black people so nonviolent?

They aren’t. See the whole of sub-Saharan Africa to see how ‘non-violent’ they are.

Damned if I know! But I wish us white folks would take a lesson from them.

Yes!! The white man has tons to learn from the criminal black man! Much to learn about taking welfare and not working!!

Blacks have 2.5 to 4.9 percent higher testosterone than whites, which is causes more violence and crime. Beaver (2014) states that blacks who have the MAOA-L 2 repeat allele have significantly highier chances of being shot, stabbed or reporting shootings and stabbings than other genotypes. Blacks also have the highest rate of the 3 repeat allele (53 percent compared to 37 percent for whites) and 2 repeat allele (5 percent compared to .1 percent for whites). Moreover, he didn’t speak about how black violent crime is genetic in nature. This is mirrored in the crime rate and how violent blacks really are.

This is the age of the Internet where we have amassed tons of human knowledge which is readily available with a few hits of a few buttons. If people still want to be ignorant spewing falsities, it’s on them. But the truth is out there for those who seek it.

Blacks are not ‘non-violent’. Go to the nearest ghetto and see how ‘non-violent’ blacks are.

Islam, Suicide Bombings, IQ and Consanguinity

1650 words

A lot of people seem to confuse causes between ‘Islam’ and behavior that’s just ‘low IQ’. Whenever these attacks like shootings, sexual assaults and rapes happen, that’s due to their low IQ; not religion. I wrote about this in IQ, Inbreeding and Clannishness. All of the behavior you see is due to low IQ. 1) being in an area with a hot climate and 2) cousin marriage has been going on there ever since Jews from the Levant introduced it to them around 200 BC. To quote myself:

Those innate behaviors which result in the favoring in all areas of life, themselves and their family, is a result of genetic similarity because of the closely related genes they share (the father’s brother’s daughter type is the most common in the Muslim world). Also, first and second cousin marriages are more common, which also result in increased altruism for their own family because of the close genetic similarity, but also those in their own group, which is mediated by the brain hormone oxytocin.

In a paper on the mean IQ of Muslims and non-Muslim countries, Donald Templer states that the Muslim world, which used to be have great intellectual achievements from the 7th to 12th centuries, has seen an underrepresentation in highly creative contributions in science journals. This is because of the inbreeding effect (2.5 to 10 point drop in IQ) of close cousin marriage. He ends up saying that genetic factors are more important than social/cultural/religious values (back to the inbreeding, causing defects and lowering IQ) in regards to IQ.

I also put a map of individualism and collectivism in Europe here. You can see that the collectivist countries are fighting back more. The countries/regions where it’s more red roughly matches up to the situation. You can see how in Central, Northern and Northwestern Europe they’re more individualistic, as well as more atheist, than those collectivist countries. So that leads to what we see with this ‘welcome refugees’ signs, as well as, I would assume, more oxytocin in the brain for Europeans, which leads to more altruism towards other peoples. Of course, 1000 years ago, the high altruism was fine due to being a mostly homogeneous society. But when others move in who are not from the area, and who do not have the same biology as you due to certain selection pressures, that’s when the ‘clash of cultures’ commences. Which it’s not really a clash of culture, more like a clash of biology, because 2 groups who shouldn’t live together are being forced to live together.

This also brings me to people who confuse the causality between Islam and blacks. As I said, it’s a low IQ religion (which I have provided enough evidence for my case). So blacks who become Muslim do so because of low IQ. Anything after that doesn’t mean that being a Muslim had them do it. Lets say that Islam never popped up and the same peoples were still there, continuing such close inbreeding, would that be Islam doing it? No. It’s their biology. **

Using environmental factors (Islam, culture) is what leftists do. In my post on behavior not equaling genes plus environment, I showed how people create their own environments based on their own genetics. The environment we put ourselves in is based on our genetics. We can clearly see that Islam is bringing their culture (genetics) to Europe and are incompatible with Europe as well as all Western societies around the world. Due to this, we can see that wherever any population goes, it will be the same from the original place they emigrated from if migration in large enough numbers occurs. A country is only as good as its majority population.

In Non-Western People are Abnormal to Our SocietiesI showed how due to differing cultures (genetics), these third-world immigrants coming into our countries cannot readily assimilate due to differing average IQs and other hormones that lead to crime differentials with the native population. Though Arabs are Caucasian, evolving closer to the equator lead to higher levels of testosterone as more exposure to the sun increases vitamin D levels, which is not a vitamin but actually a steroid hormone. These differences in testosterone then lead to more sex attacks with high testosterone combined with low IQ. Lower IQ people are less likely to be virgins than higher IQ people. This shows that higher IQ people have less testosterone and can also hold back urges more than lower IQ people. This then translates over to an increase of sexual assaults by ‘migrants’ to European women. These ‘abnormalities’, though, would be abnormal anywhere. Putting differing cultures (genetics) in a place with a completely different culture will lead to strife due to genetic distance between the two populations.

I wrote in Evolutionary Reasons for Suicide Bombings that Muslims who suicide bomb do so to increase inclusive fitness. The increase in inclusive fitness comes about due to the suicide bomber having no prospects as well as no kids, so he/she is just taking up resources. By committing suicide, they are freeing resources for others who have a better chance to spread their genes. Many suicide bombers come from middle-class backgrounds, which further proves the case for genetic interests being the cause for this. The majority of Al-Qaeda members come from educated, middle-class backgroundsEven for Palestinian suicide bombers, none of them were poor, uneducated, simple minded nor depressed.

The average IQ for a criminal is 85 adult offenders, 92 for juvenile offenders. What’s the average IQ in the Middle East? 81, around 1.3 SD lower than average, and 4 points lower for chronic adult offenders in America. The lower IQ comes from being more inbred, which then manifests itself in the crime rate. The strife in the middle east can also be traced back to IQ and consanguinity rates in those populations. How inbred a population is predicts IQ as well as how much strife occurs in those populations.

Germany has said they will begin IQ testing their ‘migrants’. If it works well (I highly doubt it will, and if it is, it won’t be implemented well) this could curb some attacks that happen. Since IQ differences between populations are one of the biggest causes for crime differentials (lower IQ is also correlated with higher testosterone) between them, screening for and only allowing high IQ ‘migrants’ in would curb some violent crime and sex attacks if implemented on a wide enough scale. IQ differences between populations are one of the biggest reasons for differences between any population you can think of.

For a comparison, we can use Christian Arabs. Christian Arabs are less inbred than Muslim Arabs, which shows in the amount of terror attacks committed by Christian Arabs, which I can’t find any data for. If anyone has found any, leave a comment. hbdchick then says this about consanguinity between Christian Arabs and Muslim Arabs:

so, the rate of cousin-marriage amongst lebanese christians was 16.5% while the rate for muslims approached double that at 29.6%.

christians married cousins more distant than first cousins at a slightly higher rate than they did first cousins: 8.6% (>1C) versus 7.9% (1C). muslims, on the other hand, favored first cousin marriage: 17.3% (1C) versus 12.3% (>1C). this is a similar pattern found elsewhere in the middle east/arab world. in egypt, for instance, copts tend to marry second cousins while muslims tend to marry first cousins (no, i can’t find the reference!).

there was also more fbd marriage amongst muslims (6.4%) versus christians (3%).

This is directly mirrored in how often we hear about Christian Arab attacks and crime (I haven’t heard of this), showing that consanguinity rates can predict crime rates. Due to this extreme inbreeding, they are more genetically similar, which leads to higher amounts of altruism for their own group, in turn leading to derogation of the out-group. Europeans are, on average, less inbred than Muslims. This is why it’s said that Muslims are incompatible with our societies. They are more clannish and altruistic for their own. Like JP Rushton said, groups will proliferate ideas that are good for their genetic interests.

Even more evidence can be shown with Chechen inbreeding. I can’t find any data on Chechen IQ, so lets use the closest country to Chechnya, which is Georgia with an average of 94. Since inbreeding can depress IQ 2.5 to 10 points, Chechnya’s average IQ should be somewhere around the mid-80s. This shows similarity with the consanguinity rate. hbdchick then concludes:

it’s no wonder, then, that they still engage in blood feuds (just like the albanians). you’d half expect them to build tower houses for protection during clan disputes like the albanians or the maniots.

oh, wait.

Muslim (Arab) populations are incompatible to Western societies due to how inbred they are. Their own societies are built on their genetics, which they then bring to the West and attempt to bring what they’re running from to their new host country.

In conclusion, whenever people say “it’s Islam doing it”, it’s low IQ behavior. Those with lower IQ are more likely to be drawn to Islam. Islam developed after 1300 years after the start of Arab inbreeding.  We can draw, from IQ from American criminals, that 85 is the sweet spot for criminality, and since criminality is correlated with low IQ more so than any other variable you can think of. A good example of this is a low IQ person coaxed into committing a crime. It’s an obvious biological difference, the sociopolitical garbage is just that, garbage. The biology drives the politics. Consanguinity rates are one of the biggest factors. You should be concerned with the biology aspect.

Note: When I say “Muslim” I mean Arab. I am also not attempting to “apologize” for terror attacks. I’m simply looking at it through the lens of evolutionary psychology. Most people who read this blog know why Africans act the way they act, and African “migrants” are no different.
