Race and Medicine: Is Race a Useful Category?

2450 words

The New York Times published an article on December the 8th titled What Doctors Should Ignore: Science has revealed how arbitrary racial categories are. Perhaps medicine will abandon them, too. It is an interesting article and while I do not agree with all of it, I do agree with some.

It starts off by talking about sickle cell anemia (SCA) and how was once thought of as a ‘black disease’ because blacks were, it seemed, the only ones who were getting the disease. I recall back in high-school having a Sicilian friend who said he ‘was black’ because Sicilians can get SCA which is ‘a black disease’, and this indicates ‘black genes’. However, when I grew up and actually learned a bit about race I learned that it was much more nuanced than that and that whether or not a population has SCA is not based on race, but is based on the climate/environment of the area which would breed mosquitoes which carry malaria. SCA still, to this day, remains a selective factor in the evolution of humans; malaria selects for the sickle cell trait (Elguero et al, 2015).

This is a good point brought up by the article: the assumption that SCA was a ‘black disease’ had us look over numerous non-blacks who had the sickle cell trait and could get the help they needed, when they were overlooked due to their race with the assumption that they did not have this so-called ‘black disease’. Though it is understandable why it got labeled ‘a black disease’; malaria is more prevalent near to the equator and people whose ancestors evolved there are more likely to carry the trait. In regards to SCA, it should be known that blacks are more likely to get SCA, but just because someone is black does not automatically mean that it is a foregone conclusion that one has the disease.

The article then goes on to state that the push to excise race from medicine may undermine a ‘social justice concept’: that is, the want to rid the medical establishment of so-called ‘unconscious bias’ that doctors have when dealing with minorities. Of course, I will not discount that this doesn’t have some effect—however small—on racial health disparities but I do not believe that the scope of the matter is as large as it is claimed to be. This is now causing medical professionals to integrate ‘unconscious bias training’, in the hopes of ridding doctors of bias—whether conscious or not—in the hopes to ameliorate racial health disparities. Maybe it will work, maybe it will not, but what I do know is that if you know someone’s race, you can use it as a roadmap to what diseases they may or may not have, what they may or may not be susceptible to and so on. Of course, only relying on one’s race as a single data point when you’re assessing someone’s possible health risks makes no sense at all.

The author then goes on to write that the terms ‘Negroid, Caucasoid, and Mongoloid’ were revealed as ‘arbitrary’ by modern genetic science. I wouldn’t say that; I would say, though, that modern genetic science has shown us the true extent of human variation, while also showing that humans cluster into 5 distinct geographic categories, which we can call ‘race’ (Rosenberg et al, 2002; but see Wills, 2017 for alternative view that the clusters identified by Rosenberg et al, 2002 are not races. I will cover this in the future). The author then, of course, goes on to use the continuum fallacy stating that since “there are few sharp divides where one set of traits ends and another begins“. A basic rebuttal would be, can you point out where red and orange are distinct? How about violet and blue? Blue and Cyan? Yellow and orange? When people commit the continuum fallacy then the only logical conclusion is that if races don’t exist because there are “few sharp divides where one set of traits ends and another begins“, then, logically speaking, colors don’t exist either because there are ‘few [if any] sharp divides‘ where one color ends and another begins.

The author also cites geneticist Sarah Tishkoff who states that the human species is too young to have races as we define them. This is not true, as I have covered numerous times. The author then cites this study (Ng et al, 2008) in which Craig Venter’s genome was matched with the (in)famous [I love Watson] James Watson and focused on six genes that had to do with how people respond to antipsychotics, antidepressants, and other drugs. It was discovered that Venter had two of the ‘Caucasian’ variants whereas Watson carried variants more common in East Asians. Watson would have gotten the wrong medicine based on the assumption of his race and not on the predictive power of his own personal genome.

The author then talks about kidney disease and the fact that blacks are more likely to have it (Martins, Agodoa, and Norris, 2012). It was assumed that environmental factors caused the disparity of kidney disease in blacks when compared to whites, however then the APOL1 gene variant was discovered, which is related to worse kidney outcomes and is in higher frequencies in black Americans, even in blacks with well-controlled blood pressure (BP) (Parsa et al, 2013). The author then discusses that black kidneys were seen as ‘more prone to failure’ than white kidneys, but this is, so it’s said, due to that one specific gene variant and so, race shouldn’t be looked at in regards to kidney disease but individual genetic variation.

In one aspect of the medical community can using medicine based on one’s race help: prostate cancer. Black men are more likely to be afflicted with prostate cancer in comparison to whites (Odedina et al, 2009; Bhardwaj et al, 2017) with it even being proposed that black men should get separate prostate screenings to save more lives (Shenoy et al, 2016). Then he writes that we still don’t know the genes responsible, however, I have argued in the past that diet explains a large amount—if not all of the variance. (It’s not testosterone that causes it like Ross et al, 1986 believe).

The author then discusses another medical professional who argues that racial health disparities come down to the social environment. Things like BP could—most definitely—be driven by the social environment. It is assumed that the darker one’s skin is, the higher chance they have to have high BP—though this is not the case for Africans in Africa so this is clearly an American-only problem. I could conjure up one explanation: the darker the individual, the more likely he is to believe he is being ‘pre-judged’ which then affects his state of mind and has his BP rise. I discussed this shortly in my previous article Black-White Differences in PhysiologyWilliams (1992) reviewed evidence that social, not genetic, factors are responsible for BP differences between blacks and whites. He reviews one study showing that BP is higher in lower SES, darker-skinned blacks in comparison to higher SES blacks whereas for blacks with higher SES no effect was noticed (Klag et al, 1991). Sweet et al (2007) showed that for lighter-skinned blacks, as SES rose BP decreased while for darker-skinned blacks BP increased as SES did while implicating factors like ‘racism’ as the ultimate causes.

There is evidence for the effect of psychosocial factors and BP (Marmot, 1985). In a 2014 review of the literature, Cuffee et al (2014) identify less sleep—along with other psychosocial factors—as another cause of higher BP. It just so happens that blacks average about one hour of sleep less than whites. This could cause a lot of the variation in BP differences between the races, so clearly in the case of this variable, it is useful to know one’s race, along with their SES. Keep in mind that any actual ‘racism’ doesn’t have to occur; the person only ‘needs to perceive it’, and their blood BP will rise in response to the perceived ‘racism’ (Krieger and Sidney, 1996). Harburg et al (1978) write in regards to Detroit blacks:

For 35 blacks whose fathers were from the West Indies, pressures were higher than those with American-born fathers. These findings suggest that varied gene mixtures may be related to blood pressure levels and that skin color, an indicator of possible metabolic significance, combines with socially induced stress to induce higher blood pressures in lower class American blacks.

Langford (1981) shows that when SES differences are taken into account that the black-white BP disparity vanishes. So there seems to be good evidence for the hypothesis that psychosocial factors, sleep deprivation, diet and ‘perceived discrimination’ (whether real or imagined) can explain a lot of this gap so race and SES need to be looked at when BP is taken into account. These things are easily changeable; educate people on good diets, teach people that, in most cases, no, people are not being ‘racist’ against you. That’s really what it is. This effect holds more for darker-skinned, lower-class blacks. And while I don’t deny a small part of this could be due to genetic factors, the physiology of the heart and how BP is regulated by even perceptions is pretty powerful and could have a lot of explanatory power for numerous physiological differences between races and ethnic groups.

Krieger (1990) states that in black women—not in white women—“internalized response to unfair treatment, plus non-reporting of race and gender discrimination, may constitute risk factors for high blood pressure among black women“. This could come into play in regards to black-white female differences in BP. Thomson and Lip (2005) show that “environmental influence and psychosocial factors may play a more important role than is widely accepted” in hypertension but “There remain many uncertainties to the relative importance and contribution of environmental versus genetic influences on the development of blood pressure – there is more than likely an influence from both. However, there is now evidence to necessitate increased attention in examining the non-genetic influences on blood pressure …” With how our physiology evolved to respond to environmental stimuli and respond in real time to perceived threats, it is no wonder that these types of ‘perceived discrimination’ causes higher BP in certain groups with lower SES.

Wilson (1988) implicates salt as the reason why blacks have higher BP than whites. High salt intake could affect the body’s metabolism by causing salt retention which influences blood plasma volume, cardiac output. However, whites have a higher salt intake than blacks, but blacks still ate twice the recommended amounts from the dietary guidelines (all ethnic subgroups they analyzed from America over-consumed salt as well) (Fulgoni et al, 2014). Blacks are also more ‘salt-sensitive’ than whites (Sowers et al 1988Schmidlin et al, 2009; Sanada, Jones, and Jose, 2014) which is also heritable in blacks (Svetke, McKeown, and Wilson, 1996). A slavery hypothesis does exist to explain higher rates of hypertension in blacks, citing salt deficiency in the parts of Africa that supplied the slaves to the Americas, to the trauma of the slave trade and slavery in America. However, historical evidence does not show this to be the case because “There is no evidence that diet or the resulting patterns of disease and demography among slaves in the American South were significantly different from those of other poor southerners” (Curtin, 1992) whereas Campese (1996) hypothesizes that blacks are more likely to get hypertension because they evolved in an area with low salt.

The NYT article concludes:

Science seeks to categorize nature, to sort it into discrete groupings to better understand it. That is one way to comprehend the race concept: as an honest scientific attempt to understand human variation. The problem is, the concept is imprecise. It has repeatedly slid toward pseudoscience and has become a major divider of humanity. Now, at a time when we desperately need ways to come together, there are scientists — intellectual descendants of the very people who helped give us the race concept — who want to retire it.

Race is a useful concept. Whether in medicine, population genetics, psychology, evolution, physiology, etc it can elucidate a lot of causes for differences between races and ethnic groups—whether or not they are genetic or psychosocial in nature. That just attests to both the power of suggestion along with psychosocial factors in regards to racial differences in physiological factors.

Finally let’s see what the literature says about race in medicine. Bonham et al (2009) showed that both black and white doctors concluded that race is medically relevant but couldn’t decide why however they did state that genetics did not explain most of the disparity in relation to race and disease aside from the obvious disorders like Tay Sachs and sickle cell anemia. Philosophers accept the usefulness of race in the biomedical sciences (Andreason, 2009Efstathiou, 2012; Hardimon, 2013Winther, Millstein, and Nielsen, 2015; Hardimon, 2017) whereas Risch et al (2002) and Tang et al (2002) concur that race is useful in the biomedical sciences. (See also Dorothy Roberts’ Ted Talk The problem with race-based medicine which I will cover in the future). Richard Lewontin, naturally, has hang-ups here but his contentions are taken care of above. Even if race were a ‘social construct‘, as Lewontin says, it would still be useful in a biomedical sense; but since there are differences between races/ethnic groups then they most definitely are useful in a biomedical sense, even if at the end of the day individual variation matters more than racial variation. Just knowing someone’s race and SES, for instance, can tell you a lot about possible maladies they may have, even if, utltimately, individual differences in physiology and anatomy matter more in regards to the biomedical context.

In conclusion, race is most definitely a useful concept in medicine, whether race is a ‘social construct’ or not. Just using Michael Hardimon’s race concepts, for instance, shows that race is extremely useful in the biomedical context, despite what naysayers may say. Yes, individual differences in anatomy and physiology trump racial differences, but just knowing a few things like race and SES can tell a lot about a particular person, for instance with blood pressure, resting metabolic rate, and so on. Denying that race is a useful concept in the biomedical sciences will lead to more—not less—racial health disparities, which is ironic because that’s exactly what race-deniers do not want. They will have to accept a race concept, and they would accept Hardimon’s socialrace concept because that still allows it to be a ‘social construct’ while acknowledging that race and psychosocial factors interact to cause higher physiological variables. Race is a useful concept in medicine, and if the medical establishment wants to save more lives and actually end the racial disparities in health then they should acknowledge the reality of race.

Sex and IQ

By Scott Jameson

800 words

Long and short of this issue is that something has to explain why most of the really, really smart people are men. There are two hypotheses: men have a higher mean, and men have a higher standard deviation. They don’t really have to compete, and so some people believe that both are true. Some believe neither, of course.

Let’s start with three facts:

  1. Women tend to get slammed by men on Raven’s Progressive Matrices; the second graph in the post linked above details this. It’s a difference of 5 IQ points on average, quite a bit, certainly more than on other IQ tests.
  2. Women tend to lose even harder in visuospatial measures. John Loehlin pointed out in The Handbook of Intelligence that the gap here was a whopping 13.5 points.
  3. Raven’s is so g loaded because your score is primarily driven by spatial and verbal-analytic abilities.

The biggest subtest difference is spatial, and I think that likely explains the abnormally large differences in Raven’s scores. Other IQ tests, like the SAT, hardly use visual abilities. Women do about as well as men on the SAT. I’ve also seen the White-Asian gap smaller on the SAT than in other IQ tests, and that gap is also driven in large part by spatial scores. Conversely you might expect the SAT to go better for a hypothetical demographic that scores well in math and verbal abilities, but not especially well in spatial. By hypothetically I mean that these people make up like a fifth of the kids at the Ivy Leagues, even more than you’d expect from an average IQ of, I don’t know, 111ish.

Off topic: these differences are probably going to be slighter still now that they’re fastidiously removing every useful element of the test in an effort to make it less “biased” by race. I wonder if colleges will just throw up their shoulders and start looking for kids who do well on the ACT. Moving on.

There are other sex differences in subtest scores. Pulling from Loehlin again: “females tend to have an advantage on verbal tests involving the fluent production of words belonging to a category, such as synonyms.” Women are known to do better on verbal than on math.

Loehlin also points out that girls do better at math in early childhood, but that boys outstrip them by the time it, uh, matters, when they take standardized tests in adolescence.

I have a wild hypothesis that men and women respectively being more oriented towards mathematical and verbal thought corresponds to observed differences in interests. Women are known to read more often than men on average, whereas male dominated activities like sports and video games often have a distinctly mathematical bent. My spurious hypothesis is that doing these different things differentially develops their abilities, constituting an example of crystallized intelligence rather than fluid intelligence; alternatively, they were differentially selected for ability to perform well on tasks that their respective sex does more of, in which case the abilities are innate.

Even if they aren’t innate, it’d be an instance of secondary heritability because evidence tends to show male-female personality differences as innate; in this scenario they are innately prone to practicing different abilities to different extents.

Loehlin points to Hedges and Nowell’s 1995 meta-analysis, showing a higher male variation in IQ and elucidating a few more small subtest differences. I’ve lifted a meaty bit here:

On average, females exhibited a slight tendency to perform better on tests of reading comprehension, perceptual speed, and associative memory, and males exhibited a
slight tendency to perform better on tests of mathematics and social studies. All of the effect sizes were relatively small except for those associated with vocational aptitude scales (mechanical reasoning, electronics information, and auto and shop information) in which average males performed much better than average females. The effect sizes for science were slightly to moderately positive, and those for perceptual speed were slightly to moderately negative. Thus, with respect to the effect size convention, these data suggest that average sex differences are generally rather small.

In summary:

  1. There are sex differences in scores of various IQ subtests, including but not limited to female orientation towards verbal and male orientation towards mathematical ability.
  2. The largest of these differences is a substantial male advantage in spatial ability.
  3. On any IQ test that doesn’t weight subtests such that men and women perform equally by default, men tend to score a hair better.
  4. Men also have a higher standard deviation in IQ.

There are more male geniuses, particularly with respect to mathematical genius. There are also more mentally retarded males. I just explained why men tend to populate CERN, NASA, Silicon Valley, and lists of who’s died in the Running of the Bulls.

r/K Selection Theory: A Response to Truth-Justice

1700 words

After the publishing of the article debunking r/K selection theory last week, I decided to go to a few places and provide the article to a few sites that talk about r/K selection theory and it’s (supposed) application to humans and psychometric qualities. I posted it on a site called ‘truthjustice.net‘, and the owner of the site responded to me:

Phillippe Rushton is not cited a single time in AC’s book. In no way, shape or form does the Theory depend on his opinions.

AC outlines a very coherent theoretical explanation for the differing psychological behavior patterns existing on a bell curve distribution in our population. Especially when it comes to the functioning of the Amygdala for which we have quite a lot of data by now.

Leftists are indeed in favor of early childhood sexualization to increase the quantity of offspring which will inevitably reduce the quality and competitive edge of children. They rank significantly lower on the moral foundations of “loyalty”, “authority” and “purity” as outlined by Jonathan Haidt’s research into moral psychology. Making them more accepting of all sorts of degeneracy, deviancy, and disloyalty to the ingroup.

http://people.stern.nyu.edu/jhaidt/

They desire a redestribution of resources to the less well performing part of our population to reduce competitive stress and advantage while giving far less to charity and being significantly more narcissistic to increase their own reproductive advantage.

https://anepigone.blogspot.com/2008/11/more-income-more-votes-republicans_13.html

Their general mindset becomes more and more nihilistic, atheistic, anarchistic, anti-authority and overall r-selected the further left you go on the bell curve. A denial of these biological realities in our modern age is ridiculous when we can easily measure their psychology and brain functionality in all sorts of ways by now.

Does that now mean that AC is completely right in his opinions on r/K-Selection Theory? No, much more research is necessary to understand the psychological differences between leftists and rightists in full detail.

But the general framework outlined by r/K-Selection Theory very likely applies to the bell curve distribution in psychological behavior patterns we see in our population.

I did respond, however, he removed my comment and banned me after I published my response. My response is here:

“Phillippe Rushton is not cited a single time in AC’s book. In no way, shape or form does the Theory depend on his opinions.”

Meaningless. He uses the r/K continuum so the link in my previous comment is apt.

“AC outlines a very coherent theoretical explanation for the differing psychological behavior patterns existing on a bell curve distribution in our population. Especially when it comes to the functioning of the Amygdala for which we have quite a lot of data by now.”

No, he doesn’t.

1) Psychological traits are not normally distributed,

2) even if r/K were a valid paradigm, it would not pertain to within species variation,

3) it’s just a ‘put these traits on one end that I don’t like and these traits at the other end that I like and that’s my team while the other team has all of the bad traits’ thing,

4) his theory literally rests on the r/K continuum proposed by Pianka. Furthermore, no experimental rationale “was ever given for the assignment of these traits [the r/K traits Pianka inserted into his continuum] to either category” (Graves, 2002: 135), and

5) the r/K paradigm was discredited in the late 70s (see Graves 2002 above for a review)

“Leftists are indeed in favor of early childhood sexualization to increase the quantity of offspring which will inevitably reduce the quality and competitive edge of children. They rank significantly lower on the moral foundations of “loyalty”, “authority” and “purity” as outlined by Jonathan Haidt’s research into moral psychology. Making them more accepting of all sorts of degeneracy, deviancy, and disloyalty to the ingroup.”

I love Haidt. I’ve read his book and all of his papers and articles. So you notice a few things. Then see the (discredited) r/K paradigm. Then you say “oh! liberals are bad and are on the r side while conservatives are K!!”

Let me ask you this: where does alpha-selection fall into this?

“They desire a redestribution of resources to the less well performing part of our population to reduce competitive stress and advantage while giving far less to charity and being significantly more narcissistic to increase their own reproductive advantage.”

Oh.. about that… liberals have fewer children than conservatives. Liberals are also more intelligent than conservatives. So going by Rushton’s r/K model, liberals are K while conservatives are r (conservatives are less intelligent and have more children). So the two cornerstones of the (discredited) r/K continuum show conservatives breeding more and also are less intelligent while it’s the reverse for liberals. So who is ‘r’ and ‘K’ again?

“Their general mindset becomes more and more nihilistic, atheistic, anarchistic, anti-authority and overall r-selected the further left you go on the bell curve. A denial of these biological realities in our modern age is ridiculous when we can easily measure their psychology and brain functionality in all sorts of ways by now.”

‘r’ and ‘K’ are not adjectives (Anderson, 1991: 57).

Why does no one understand r/K selection theory? You are aware that r/K selection theory is density-dependent selection, correct?

“Does that now mean that AC is completely right in his opinions on r/K-Selection Theory? No, much more research is necessary to understand the psychological differences between leftists and rightists in full detail.”

No, he’s horribly wrong with his ‘theory’. I don’t deny psych differences between libs and cons, but to put them on some (discredited) continuum makes no sense in reality.

“But the general framework outlined by r/K-Selection Theory very likely applies to the bell curve distribution in psychological behavior patterns we see in our population.”

No, it doesn’t. Psych traits are not normally distributed (see above). Just like Rushton, AC saw that some things ‘fit’ into this (discredited) continuum. What’s that mean? Absolutely nothing. He doesn’t even cite papers for his assertion; he called Pianka a leftist and said that he tried to sabotage the theory because he thought that it described libs (huh? this makes no sense). AC is a clear ideologue and is steeped in his own political biases as well as wanting to sell more copies of his book. So he will not admit that he is wrong.

Let me ask you a question: where did liberals and conservatives evolve? What selective pressures brought about these psych traits in these two ‘populations’? Are liberals and conservatives local populations?

I’ve also summarily discredited AC and I am waiting on a reply from him (I will be surprised if he replies).


However, unfortunately for AC et al, concerns have been raised “about the use of psychometric indicators of lifestyle and personality as proxies for life history strategy when they have not been validated against objective measures derived from contemporary life history theory and when their status as causes, mediators, or correlates has not been investigated” (Copping, Campbell, and Muncer, 2014). This ends it right here. People don’t understand density-dependent/independent selection since Rushton never talked about it. That, as has been brought up, is a huge flaw in Rushton’s application of r/K theory to the races of Man.

Liberals are, on average, more intelligent than conservatives (Kanazawa, 2010; Kanazawa, 2014) Lower cognitive ability has been linked to greater prejudice through right-wing ideology and low intergroup contact (Hodson and Busseri, 2012), with social conservatives (probably) having lower IQs. There are also three ‘psychological continents’—Europe, Australia, and, Canada and are the liberal countries whereas Southeast Asia, South Asia, South America and Africa contain more conservative countries with all other countries including Russia, the US and Asia in the middle and “In addition, gross domestic product (GDP) per capita, cognitive test performance, and governance indicators were found to be low in the most conservative group and high in the most liberal group” (Stankov and Lee, 2016). Further, economic liberals—as a group—tend to be better educated than Republicans—so intelligence is positively correlated with socially and economically liberal views (Carl, 2014).

There is also a ‘conservative baby boom‘ in the US—which, to the Rushtonites, is ‘r-selected behavior’. Furthermore, women who reported that religion was ‘very important to them’ reported having higher fertility than women who said that it was ‘somewhat important’ or ‘not important’ (Hayford and Morgan, 2008). Liberals are more likely to be atheist (Kanazawa, 2010), while, of course, conservatives are more likely to be religious (Morrison, Duncan, and Parton, 2015; McAdams et al, 2015).

All in all, even if we were to allow the use of liberals and conservatives as local populations, like Rushton’s erroneous use of r/K theory for human races, the use of r/K theory to explain the conservative/liberal divide makes no sense. People don’t know anything about ecology, evolution, or neuroscience. People should really educate themselves on the matters they speak about—I mean a full-on reading into whatever it is you believe. Because people like TIJ and AC are clearly idealogues, pushing a discredited ecological theory and applying it to liberals and conservatives, when the theory was never used that way in the first place.

For anyone who would like a look into the psychological differences between liberals and conservatives, Jonathan Haidt has an outstanding book outlining the differences between the two ideologies called The Righteous Mind: Why Good People are Divided by Politics and ReligionI actually just gave it a second read and I highly, highly recommend it. If you want to understand the true differences between the two ideologies then read that book. Try to always remember and look out for your own biases when it comes to your political beliefs and any other matter.

For instance, if you see yourself frantically attempting to gather support for a contention in a debate, then that’s the backfire effect in action (Nyhan and Reifler, 2012), and if you have a knowledge of the cognitive bias, you can better take steps to avoid such a heavy-handed bias. This, obviously, occurred with TIJ. The response above is airtight. If this ‘continuum’ did exist, then it’s completely reversed with liberals having fewer children and generally being more intelligent with the reverse for conservatives. So liberals would be K and conservatives would be r (following Rushton’s interpretation of the theory which is where the use of the continuum comes from).

Testosterone and Aggressive Behavior

1200 words

Testosterone gets a bad rep. People assume that if one has higher testosterone than average, that they will be a savage, bloodthirsty beast with an insatiable thirst for blood. This, however, is not the case. I’ve documented how testosterone is vital for male functioning, and how higher levels don’t lead to maladies such as prostate cancer. Testosterone is feared for no reason at all. The reason that people are scared of it is that of the anecdotal reports that individual A had higher testosterone when he committed crime B so, therefore, anyone who commits a crime has higher testosterone and that is the ultimate—not proximate—cause of crime. This is erroneous. There is a positive—albeit extremely low—correlation between physical aggression and violence at .14. That’s it. Furthermore, most of these claims of higher levels of testosterone causing violence is extrapolated from animal studies to humans.

Testosterone has been shown to lead to violent and aggressive behavior, largely only in animal studies (Archer, 1991; Book et al, 2001). For years, the relationship between the two variables was thought to be causal, i.e., high levels of testosterone cause violent crimes, which has been called into question over recent years. This is due to how the environment can raise testosterone levels. I have documented how these environmental factors can raise testosterone—and after these events, testosterone stays elevated.

Largely, animal studies are used to infer that high levels of testosterone in and of themselves lead to higher rates of aggression and therefore crime. However, two important meta-analyses show this is not necessarily the case (Archer, 1991; Book et al, 2001). Book et al, 2001 showed that two variables were important in seeing the relationship between aggression and crime—the time of day that the assay was taken and the age of the participant. This effect was seen to be largest in, not unexpectedly, males aged 13-20 (Book et al, 2001: 594). So since age confounds the relationship between aggression and testosterone in males, that is a variable that must also be controlled for (which, in the meta-analyses and other papers I cite on black and white testosterone is controlled for).

More interestingly, Book et al (2001) showed that the nature of the measure of aggression (self-reported or behavioral) did not have any effect on the relationship between testosterone and aggression. Since there is no difference between the two measures, then a pencil-and-paper test is a good enough index of measure of aggression, comparable to observing the behavior of the individual studied.

Archer (1991) also showed the same low—but positive—correlations between aggression and testosterone. Of course, as I’ve extensively documented since there is a positive relationship between the two variables does not necessarily mean that high-testosterone men commit more crime—since the outcome of certain situations can increase and decrease testosterone, no causal factors have been detangled. Book et al (2001) confirmed Archer’s (1991) finding that the correlation between violent and aggressive behavior was positive and low at .14.

Valois et al (2017) showed there was a relationship between emotional self-efficacy (ESE) and aggressive and violent behaviors in a statewide sample of high school children in South Carolina (n=3,386). Their results suggested that there was a relationship between carrying a weapon to school within the past 30 days along with being injured with a club, knife or gun in the past 12 months was significantly associated with ESE for specific race and sex groups.

Black girls who reported a low ESE reported carrying a weapon to school 30 days prior to the survey were 3.22 times more than black girls with a high ESE who did not report carrying a weapon to school within the past 30 days prior to the questionnaire. For black boys with low ESE, they were 3.07 times more likely to carry a weapon to school within the past 30 days in comparison to black boys with high ESE who did not carry a weapon to school in the past 30 days. White girls who reported low ESE had the highest chance of bringing a weapon to school in comparison to white girls with low ESE—they were 5.87 times more likely to carry a weapon to school 30 days prior to the survey. Finally, white boys with low ESE were slightly more than 2 times more likely than white boys with high ESE to carry a weapon to school 30 days prior to the survey.

Low ESE in white and black girls is associated with carrying a weapon to school, whereas low ESE for white and black boys is associated with being threatened. Further, their results suggested that carrying a weapon to school was associated with low ESE in black and white girls suggesting that low ESE is both situation-specific and specific to the female sex. The mediator between these things is low ESE—it is different for both black boys and black girls, and when it occurs different courses of action are taken, whether it’s through bringing a weapon to school or being threatened. What this tells me is that black and white boys with low ESE are more likely to be threatened because they are perceived to be more meek, while black and white girls with low ESE that get provoked at school are more likely to bring weapons. So it seems that girls bring weapons when provoked and boys fight.

The two meta-analyses reviewed above show that there is a low positive (.14) correlation between testosterone and aggression (Archer, 1991; Book et al, 2001). Thusly, high levels of testosterone on their own are not sufficient enough to explain high levels of aggression/violence. Further, there are race- and sex-specific differences when one is threatened at high school with black and white boys being more likely to report being threatened more (which implies a higher rate of physical fighting) while black and white girls when threatened brought weapons to school. These race- and sex-specific differences in the course of action taken when they are physically threatened needs to be looked into more.

I’d like to see the difference in testosterone levels for a matched sample of black and white boys from two neighboring districts with different murder rates as a proxy for the amount of violence in the area. I’d bet that the places with a higher murder rate would have children 1) report more violence and instances of bringing weapons to school and 2) report more harm from these encounters—especially if they have low ESE as seen in Valois (2017) and 3) the children in the high schools along with the residents of the area would have higher testosterone than the place with less violence. I would expect these differences to be magnified in the direction of Valois (2017) in that areas with higher murder rates would have black and white girls report bringing weapons to school when threatened whereas black and white boys would report more physical violence.

High testosterone itself is not sufficient enough to explain violence as the correlation is extremely low at .14. Testosterone levels fluctuate depending on the time of day (Brambilla et al, 2009; Long, Nguyen, and Stevermer, 2015) to the time of year (Stanton, Mullette-Gillman, and Huettel, 2011Demur, Uslu, and Arslun, 2016). How the genders/races react differently when threatened in adolescence is interesting and deserves further study.

Biases and Political Beliefs

2150 words

The study of political bias is very important. Once the source of what motivates political bias—which no doubt would translate to other facets of life—is found, individual action can be taken to minimize any future bias. Two recent studies found that contrary to other studies showing that conservatives are more biased than liberals, both groups were equally as biased.

Everyone is biased—even physicians (Cain and Detsky, 2008). When beliefs we hold to be true are questioned, we do anything we can to shield ourselves from conflicting information. Numerous studies have looked into biases in politics, with some studies showing that conservatives are more likely to be biased towards their views more than liberals. However, recent research has shown that this is not true.

Frimer, Skitka, and Motyl, (2017) showed there were similar motives to shield one’s self from contradictory information. Hearing opposite viewpoints—especially for staunch conservatives and liberals—clearly leads to them doing anything possible to, in their heads, defend their dearly held beliefs. In four studies (1: people would forgo the chance to win money if they didn’t have to hear the opposite sides’ opinions on the same-sex marriage debate; 2: thinking back to the 2012 election; 3: upcoming elections in the US and Canada; “a range of other Culture War Issues” (Frimer, Skitka, and Motyle, 2017); and 4: both groups reported similar diversions towards hearing the opposite group’s beliefs), both groups reported that hearing the other side’s beliefs would induce cognitive dissonance (Frimer, Skitka, and Motyle, 2017). They meta-analyzed all of their studies and still found that both groups would “rather remain in their ideological bubbles”.

Ditto et al (2017) also had similar findings. They meta-analyzed 41 studies with over 12,000 participants, testing two hypotheses: 1) conservatives would be more biased than liberals and 2) there would be equal amounts of bias. They discovered that the correlation for partisan bias was “robust”, with a correlation of .254. They showed that “liberals (r = .248) and conservatives (r = .247) showed nearly identical levels of bias across studies” (Ditto et al, 2017).

These two studies show what we know is true: it’s extremely hard/damn near impossible to change one’s view. Someone can be dead wrong, yet attempt to gather up whatever kind of data they possibly can to shield themselves from the truth.

This all comes down to one thing: the backfire effect. When we are presented with contradictory information, we immediately reject it. Everyone is affected by this bias. One study showed that corrections frequently failed to correct political misconceptions, with these attempted corrections actually doing the opposite, people increased their misconception of the group in question (Nyhan and Riefler, 2010). The thing is, people lack the knowledge about political matters which then affects their opinions. These studies show why it’s next to impossible to change one’s view in regards to anything, especially political matters.

New York University’s Professor of Ethical Leadership and social psychologist with a specialty in morality Jonathan Haidt also talks about partisan bias in his outstanding book on religion and politics The Righteous Mind: Why Good People are Divided by Politics and Religion (Haidt, 2013). This book is outstanding and I highly recommend it. I’ve written about some of his thoughts in his book, his theory on the evolution of morality is very well argued. Moral reasoning is just a post-hoc search for reasons to justify the judgments that people have already made. When asked why people are so averse to questions they find morally wrong, they cannot give good reasons to why they find the scenarios morally wrong (Haidt, 2001). More specifically, people couldn’t say why it was morally wrong to have sex with a sibling even though they were told that they used birth control and both enjoyed the act, suffering no emotional damage. This is direct evidence for Haidt’s ‘wag-the-dog’ illusion.

Haidt (2001: 13) writes:

 If moral reasoning is generally a post-hoc construction intended to justify automatic moral intuitions, then our moral life is plagued by two illusions. The first illusion can be called the “wag-the-dog” illusion: we believe that our own moral judgment (the dog) is driven by our own moral reasoning (the tail). The second illusion can be called the “wag-the-otherdog’s-tail” illusion: in a moral argument, we expect the successful rebuttal of an opponent’s arguments to change the opponent’s mind. Such a belief is like thinking that forcing a dog’s tail to wag by moving it with your hand should make the dog happy.

Except the opponent’s mind is never changed. People always search for things to affirm their worldviews.

In his book, Haidt cites a study done on 14 liberals and conservatives who were stuck into an fMRI machine to scan their brains when shown 18 slides to see how their brain changed when viewing them (Weston et al, 2006). The first of which slide one set was George W. Bush praiding Ken Lay, the CEO of Enron. After, they were shown a slide in which the former President avoided mentioning Lay’s name. “At this point, Republicans were squirming” (Haidt, 2013: 101). Then they were finally shown a slide that said that Bush “felt betrayed” by the CEO’s actions and was shocked to find out that he was corrupt. There was a set of similar slides showing similar contradictory statements from John Kerry. The researchers had engineered situations that made the individual uncomfortable when shown their candidate contradicted themselves, while at the same time not showing any signs of being uncomfortable when it was shown their ideological opposite was caught being a hypocrite (Haidt, 2013: 101).

This study shows that emotional and intuitive processes are the causes for such extreme biases, with one only employing reasoning when it supports their own conclusions. Weston et al (2006) saw that when the individuals looked at the final slides, they had a sense of ‘escape’ and ‘release’. They cite further studies showing that this sense of escape and release is associated with the release of dopamine in the nucleus accumbens and dorsal striatum in other animals (Weston et al, 2006). So the subjects experienced this small hit of dopamine when they saw the final slide that showed everything was “OK”. If this is true, then this explains why we engage in these ‘addictive behaviors’—believing things with such conviction, even when shown contradictory information.

Like rats that cannot stop pressing a button, partisans may be simply unable to stop believing weird things. The partisan brain has been reinforced so many times for performing mental contortions that free it from unwanted beliefs. Even partisanship may be literally addictive. (Haidt, 2013: 103)

Haidt has also been covering the recent University protests that have been occurring around the country. About fifty years ago, a judge predicted the political turmoil we see in Universities today, writing:

No one can be expected to accept an inferior status willingly. The black students, unable to compete on even terms in the study of law, inevitably will seek other means to achieve recognition and self-expression. This is likely to take two forms. First, agitation to change the environment from one in which they are unable to compete to one in which they can. Demands will be made for elimination of competition, reduction in standards of performance, adoption of courses of study which do not require intensive legal analysis, and recognition for academic credit of sociological activities which have only an indirect relationship to legal training. Second, it seems probable that this group will seek personal satisfaction and public recognition by aggressive conduct, which, although ostensibly directed at external injustices and problems, will in fact be primarily motivated by the psychological needs of the members of the group to overcome feelings of inferiority caused by lack of success in their studies. Since the common denominator of the group of students with lower qualifications is one of race this aggressive expression will undoubtedly take the form of racial demands–the employment of faculty on the basis of race, a marking system based on race, the establishment of a black curriculum and a black law journal, an increase in black financial aid, and a rule against expulsion of black students who fail to satisfy minimum academic standards.

This seems to have come true today, seeing as political diversity has decreased in psychology, for instance, in the past fifty years (Duarte et al, 2015). In America, they found that 58-66 percent of social science professors identified as liberals, whereas only 5-8 percent identified as conservatives. Self-identified Democrats also outnumbered Conservatives by almost 8 to 1. Other researchers found that 52 to 77 percent of humanities professors were liberal with only 4-8 percent identifying as Conservative, for a ratio of about 5 to 1, favoring liberals. Finally, 84 percent of psychologists identified as liberal, with only 8 percent identifying as conservative for a 10.5 to 1 ratio (Duarte et al, 2015). However, this skew has only existed for about fifty years. When our institutions show this heavy skew in political beliefs, self-affirming, self-fulfilling prophecies will affect the quality of what is taught to students which will have a negative effect on the type of education received. 

Finally, when talking about political biases, one cannot go without mentioning Stephen Jay Gould. Although I’ve come to love his work on evolutionary theory, he was horribly wrong on human differences and let his motivations, biases and political views cloud his judgement and drive him to be grossly dishonest in his posthumous attacks of a man long dead who could no longer defend himself in one Samuel Morton, which first appeared in 1978. This culminated in his widely acclaimed (and, as fas as I can tell, still given to college students to read) book Mismeasure of Man (Gould, 1981). In the book, he attacked Morton for being biased in his measurements of his skull collection. However, in 2011, an anthropology team lead by Jason Lewis remeasured Morton’s skulls and found that Morton was not biased and his measurements were correct (Lewis et al, 2011). Gould was the one who ended up showing the huge bias that he accused Morton of and, ironically for Gould, he was the case study in avoiding bias in scholarship and science, not Morton.

However, as is usually the case, long debates such as this are not so easily settled. Philosopher Michael Weisberg (Weisberg, 2014) argued that Gould’s arguments against Morton were sound and that “Although Gould made some errors and overstated his case in a number of places, he provided prima facie evidence, as yet unrefuted, that Morton did indeed mismeasure his skulls in ways that conformed to 19th century racial biases.” Further, Kaplan, Pigliucci and Banta (2015) argue that Gould’s problem with Morton’s measurements came down to how the measurements should have been done (lead shot or seed). They contend that many of Lewis et al’s (2011) claims against Gould were “misleading” and “had no relevance to Gould’s published analysis.” They also argue that both Gould’s and Morton’s methods (inclusion/exclusion of skulls, how to compute averages, etc) were “inappropriate”. Nevertheless, the point is, this debate seems to be far from over and I await the next chapter. Whatever the case may be, Gould vs. Morton is a perfect case of politics and bias in science.

Everyone is biased. Researchers, physicians, normal everyday people, etc. But where we become most biased is when politics comes into play. To become better, well-rounded people with a myriad of knowledge, we need to listen to other’s viewpoints without immediately rejecting them. But, first, we must recognize the cognitive bias and attempt to correct it. Political differences begin in the brain and then are shaped by experience. These political differences then lead to feelings of disgust when hearing of the views of the ‘opposite team’. Both sides of the political spectrum are equally as biased, contrary to each groups’ perception of this particular issue. There are differences in the brain between Conservatives and Liberals, and when they see their ‘enemy’ engage in contradictory behavior they get joy, whereas when they see their guy engage in the same contradictory behavior they show disgust.

The long debate on Morton’s skulls that’s been raging for over forty years is the perfect look into how politics, motivation, and bias comes into effect in science, no matter which camp ultimately ends up being right (I’m in the Morton camp, obviously). Studying the causes and effects of why we have such strong biases can lead to a better understanding of the causes of these underlying defense mechanisms—the causes of the backfire effect and similar cognitive biases. Everyone and anyone—from the scientist to the layman—should always let what the facts say guide their points of view and not their emotions.

When you are studying any matter, or considering any philosophy, ask yourself only what are the facts and what is the truth that the facts bear out. Never let yourself be diverted either by what you wish to believe, or by what you think would have beneficent social effects if it were believed. But look only, and solely, at what are the facts. That is the intellectual thing that I should wish to say.Bertrand Russel, 1959

Stockholm 5000 BC

by Scott Jameson

350 words

Stockholm Syndrome is when you identify with people who capture and, in some cases, abuse you. I’ve heard two pretty good explanations for this phenomenon. One is that female mammals like powerful male mammals. Makes sense. The other is that abducted people are attempting to maximize their own chances of survival, and perhaps those of any children they already have. Also makes sense. Let me present a third.

Intra-female competition. Imagine that a woman from tribe B is forcibly inducted into tribe A. The women from tribe A know all of the customs of tribe A, speak the language and so on, and they have known the men from tribe A since childhood. All else equal, what does the woman from tribe B have going for her- novelty, perhaps? That’ll wear off pretty quick, likely faster than it takes for her to get familiarized with her new culture. How can she possibly compensate? How can she compete with the women from tribe A for quantity and social status of offspring?

Lots and lots of asabiyah. If she were that much more devoted to her captors, to their religion, and so on, the men may admire her, or perhaps begin to consider her truly one of “their own,” thereby reducing the disadvantage by comparison to the women from tribe A.

All of these line up with the common belief- which I cannot seem to find strong evidence for or against, but here’s a study that mentions a sample of 21 Stockholm cases wherein 18 were women– that women tend to “suffer” from Stockholm Syndrome more often than men.

It’s not a disease in the Darwinian sense, it’s a behavioral response mechanism. The more accurate term is Capture Bonding.

Any one of these three hypotheses may explain it, or perhaps any combination of the three, or maybe something else. You would have to determine selective pressures operating on women currently in a situation wherein capture bonding is common, for example determining which behaviors enabled one war bride to have more children than another.

The Threat of Increasing Diversity: Why Many White Americans Supported Trump in the 2016 Presidential Election

3250 words

Tl;dr: White Americans exposed to more diversity are more likely to support Trump, anti-PC speech and anti-immigration policies while showing less support and positivity towards Democratic candidates. In the racial shift group, whites with low racial identity, ethnic replacement didn’t seem to care about ethnic replacement and showed stronger support for Democratic candidates. To wake up more whites to anti-immigration sentiments and white identity politics, you need to show them the effects of diversity in the social context as well as what a demographic replacement will mean in the next two decades.

Why did so many white Americans support Donald Trump’s Presidency? The reasons are numerous, though there are some key reasons why he won. To look at the exact reasons why, we need to look at some evolutionary psychology as well as political psychology. I came across a paper today titled The threat of increasing diversity: Why many White Americans support Trump in the 2016 presidential election, it has many thought provoking things in it and pretty much confirms what the altright says about an increase in white identity occurring. An ‘ethnic awakening’ if you will. The authors state that white Americans high in racial identity will be more likely to derogate out-groups when white Americans realize they are becoming replaced in their own country.

Major, Blojorn and Blascovich (2016) state that reminding white Americans who are ‘high in ethnic identification’ (i.e., a white identitarian, an altrighters) that non-white populations will soon outnumber whites caused them to be more concerned about the future of whites in America, pushing them towards Trump and his anti-immigration policies. This also led to an increase in being politically incorrect. Moreover,  whites low in ethnic identification (say, a progressive leftist) showed no greater chance in voting for Trump nor his anti-immigration policies. This did, however, decrease positivity towards Trump as well as decreased their opposition towards political correctness. The authors write:

The U.S. Census Bureau (2012) projects that the national population of non-White racial groups will exceed that of Whites before the middle of this century. Many White Americans in the US view race relations as “zero-sum,” in which status gains for minorities means status loss for Whites (Wilkins & Kaiser, 2014) and less bias against minorities means more bias against Whites (Norton & Sommers, 2011). The belief that Whites are losing out to ethnic minorities is particularly prevalent among Trump supporters (De Jonge, 2016).

This is noticed, anecdotally speaking and you can follow the citations to get more information. From an evolutionary perspective, this does make sense. Competition for resources between groups trigger evolutionary instincts. More non-whites in America will decrease the white population who has the lowest birth rate by ethnicity in the country and this will trigger more anti-immigration sentiments in whites high in ethnic identification. This ‘zero-sum game’, the ‘if your ethnic group has more than mine has less’ game will start to take hold in America in the next coming years if this paper is any indication of the future. The one particularly interesting point the authors bring up is that if there is “less ‘bias against minorities, there will be more minorities against whites”, and that, in turn, increased anti-immigration sentiments as well as drove people towards Trump and his anti-immigration views.

The more minorities that come into the country, the more whites in America will start to band together for their own ethnic genetic interests, move towards more conservative policies and begin to show more derogation towards the out-group.

The authors use the term ‘group status threat’, which is when one “worries that his group’s status, influence, and position in the hierarchy is under threat.” This threat then predicts out-group derogation. I wonder if oxytocin (a brain peptide that increases out-group derogation) increases when diversity occurs in the social context. I’d like to see that looked into one day.

There is also ‘integrated threat theory’ where increased diversity poses a threat to white Americans’ resources and American values. They also state, using social cognition theory, that increases in diversity will be ‘frightening’ and ‘confusing’ to whites, causing “uncertainty and fear”, which then drove whites towards more conservative anti-immigration policies.

When whites high in ethnic identification were shown a newspaper article stating that whites would be a minority by 2042, it led whites to be more concerned about whites’ social status in the country, leading them towards more conservative views and policies. It’s important to note that their views changed along with their policy recommendations.

In this study, the authors tested experimentally whether reminding white Americans that of the increasing diversity in the US affects their political leanings, whether or not group status is the cause of the political leanings when one hears about ethnic replacements, and whether or not ethnic identification or political alignment moderated the effects. They expected that reminding whites of ethnic replacement will cause them to lean towards conservative views and politicians (Trump, Kasich, Cruz) while decreasing support for Democrats (Clinton and Sanders).

People who experience ‘group status threat’ will be more likely to vote for Trump since he has more anti-immigration, antidiversity views than all politicians who ran for President. This, the researchers hypothesized, would come to fruition in their study. They also predicted that reminding white Americans of ethnic replacement would cause them to support more anti-immigration policies and be more resistant to political correctness, i.e., they would be more likely to be against positive policies for the out-group. They would become intolerant towards the out-group upon exposure to the reality of ethnic replacement in the country.

We also tested ethnic identification and political affiliation as potential moderators of the predicted effect of condition.1 Drawing on social identity theory (Tajfel & Turner, 1986), we expected that reminders of increasing ethnic diversity would be especially threatening to Whites whose race/ethnicity is a central aspect of their identity. Thus we expected them to report greater support for Republican candidates, anti-immigrant policies, and opposition to political correctness in response to reminders of the racial shift compared to Whites low in ethnic identification. In contrast, based on Craig and Richeson’s (2014b) finding that reminders of the racial shift increased support for conservative ideology irrespective of political leanings, we did not expect political affiliation to moderate effects.

Whites whose ‘race/ethnicity is a central aspect of their identity’, i.e. altrighters were predicted to be especially threatened at the reminder of ethnic replacement in their country of birth. However, as expected and what is seen in anecdotal accounts, whites low in ethnic identification, i.e., progressive leftists, antifas, etc, showed the opposite.

The researchers had a sample consisting of 450 white Americans with the following political beliefs: 262 Democrats, 114 Republicans, 50 Independents and 24 ‘other’. After removing the Independents and ‘others’ from the sample they had 376 white American participants (51.1 percent female).

They were given articles and were given two minutes to read them. One was an article talking about the ethnic replacement of whites and whites’ minority status in America that’s projected to occur by 2042 (aptly called ‘racial shift’) while the other article used “similar language to indicate geographic mobility is increasing (control condition).” It’s interesting to note that it seems like the only difference between the two articles is the wording. After reading the articles, they then completed tasks assessing group status threat, support for the current candidates running for office, anti-immigration sentiments, ethnic identification, and opposition to political correctness. After the completion of the tasks, they were then told the reason for the study and compensated their one dollar.

White Americans exposed to ‘racial shift condition’ reported greater group status threat than those in the control condition. This shows that white Americans who live in a diverse neighborhood will be more likely to be affected by the ‘racial shift condition’, leading them towards anti-immigration sentiment, a strong feeling towards white identity, and be more likely to hold more right-wing views. Whites high in ethnic identification showed greater group status threat than the control (.29) in the racial shift condition while whites low in ethnic identification did not. So, white identitarians showed a greater feeling of threat towards the group than did progressive leftists and antifas. Can’t say I’m too surprised. I did theorize in my article on the rise of the altright that either leftists have less oxytocin and altrighters have more, or that since political beliefs are heritable that high amounts of oxytocin will have one gravitate towards using their altruistic tendencies for the out-group or the in-group. This seems to be some evidence for my theory. For both right-wingers and left-wingers, ethnic identification was positively related to group status threat, but it was stronger in right-wingers. Even more evidence for my oxytocin/political beliefs theory.

White identitarians (whites high in ethnic identification) reported moderately greater positivity towards Trump as well as an even greater chance of voting for him in the racial shift scenario compared to the geographic movement scenario. Conversely, whites low in ethnic identification (progressive leftists, antifas, etc) showed less positivity towards Trump in the racial shift condition than in the geographic movement (control) condition,. However, in the racial shift condition, when one had high ethnic identification it led to increased positivity and a higher chance of voting for Trump. However, in the geographic condition, ethnic identification was unrelated to positivity towards Trump as well as voting for him.

Whites who showed less identification showed somewhat less support towards Sanders, being somewhat less likely to vote for him in the racial shift condition than in the geographic movement condition. In whites low in ethnic identity, neither condition (racial shift or geographic movement) had any effect on voting for Sanders or positivity towards him. Now here’s the good part: in the racial shift condition, whites high in ethnic identity showed somewhat less support and positivity towards Sanders in the racial shift condition compared to the geographic shift condition. Moreover, in the racial shift condition, ethnic identification was negatively correlated with positivity and chance of voting for Sanders, whereas in the control condition ethnic identification showed no effect.

In the racial shift condition, white identitarians were more supportive of anti-immigration policies than progressive leftists, while whites low in ethnic identification showed no difference, regardless of the condition. Ethnic identification was related to anti-immigration policies in both the racial shift and geographic movement conditions, but it was stronger in the racial shift condition.

White identitarians did not differ in outlook on political correctness by condition, while whites who show less ethnic identity reported less opposition to political correctness. Ethnic identification and anti-PC views were positively related in the racial shift condition but unrelated in the geographic shift condition.

Exposure to the racial shift condition vs. the geographic movement condition elicits different responses based on one’s political alignment and ethnic identification. Exposure to the racial shift condition increased group status threat, support for Trump and support for anti-immigration policies while somewhat decreasing support for Sanders, but only among whites high in ethnic identification. Conversely, for whites low in ethnic identification in exposure to the racial shift, there was no effect on group status threat, support for Sanders or anti-immigration sentiments and actually led to a decrease in positivity for Trump. That’s pretty powerful right there.

The support and election of Donald Trump is showing a paradigm shift in this country as ethnies in America start voting on racial lines. As diversity continues to increase and as more white Americans begin to realize the ethnic replacement will begin to impede on how many resources they have access to as well as the ‘racism being flipped on them’ with ‘less bias on minorities being more bias towards whites’, more and more whites will start voting not on party lines, but ethnic lines like all other ethnies in this country do. In the racial shift group, whites high in ethnic identification showed increased support for Trump and anti-immigration policies, increased opposition towards political correctness and decreased Sanders support through group status threat. Conversely, in the racial shift group, reminders of ethnic replacement in whites low in ethnic identification showed decreased Trump support and his policies and did not lead to group status threat. This can be termed ‘ethnic suicide’. Clearly, increased diversity is a threat to some but not all white Americans.

What boggles my mind is that when whites low in ethnic identification were reminded of the projected ethnic replacement by 2042, they decreased support for Trump and increased support for anti-immigration policies and their support for norms that prohibit bias in hate speech, which was not mediated by the group status threat. The authors put forth one theory why this may be the case. They say that whites low in ethnic identification were thinking of the changing racial demographics on the country as a whole, not just on their own ethnic group which may have led them to support a candidate who is tolerant of diversity and antibias norms. Reminding Americans high in racial identity of ethnic replacement increasingly shifted support to Trump and away from Sanders. Though this effect was not seen in relation to other candidates, the authors attributed this to Trump’s stance on immigration and political correctness relative to the other Republican candidates. To those white Americans with a high racial identity who experience group status threat, they would be drawn to Trump and his anti-immigration, anti-PC speech. The authors state:

Of all of the candidates, Trump has been most vocal in his opposition to “outsiders” such as Muslims and illegal immigrants from Latin America, and most openly critical of “political correctness” in both his rhetoric and his behavior. Trump’s rhetoric and policies thus appear to hold special appeal for White Americans highly in racial/ethnic identification who are concerned about the declining position of Whites in American society and who often perceive reverse discrimination as prevalent. In contrast, Sanders may have been perceived as the most inclusive candidate and thus most likely to exacerbate threats to White’s status as a group.

This sums up the 2016 election in one paragraph. White Americans high in racial identity showed a greater chance to vote for Trump, greater opposition to political correctness and were more likely to espouse anti-immigration sentiments.

Political leaning affiliation had a large and expected effect on candidate choice as well as policy preferences. Compared to Dems, Republicans reported much stronger support for Republican candidates than Democratic candidates while being more supportive of anti-immigration and “more un-PC attitudes”. However, when reminded of ethnic replacement, both Democrats and Republicans who showed high racial identification were more likely to lean right and vote Trump. This study shows important implications about group identity and intergroup process to voting preferences. In whites high in racial identity, increased racial diversity affects voting preferences amongst whites, with the strength of the racial/ethnic identity moderating the effect. I.e., the stronger a racial identity one has the more likely they are to support Trump and anti-immigration policies, irrespective of political leaning. Due to this study, psychologists and political scientists need to begin to pay attention to the increasing concerns of whites high in racial identification, while traditionally thinking that white Americans’ politics weren’t driven by white identity, deeming them to be unimportant to whites’ political outlooks. For example, one study showed that “racial identification, perceptions of discrimination, and linked fate were only weak predictors of White Americans’ attitudes on policies related to race and immigration. This led them to conclude that “Whites’ whiteness is usually likely to be no more noteworthy to them than is breathing the air around them” (Sears and Savelli, 2006, p. 901).

However, the current political climate shows that this no longer is the case. As more non-whites immigrate into America, whites who have high racial identity, irrespective of political leaning, will become more open to supporting Trump (or people like him) as well as anti-immigration policies. As the white majority in America shrinks, more and more white Americans will be open to white identity politics to get back their rightful resources in the country as well as the demographic majority. Eventually, with more and more unchecked immigration, white identity will start to become a central part in white American politics and voting blocks. White Americans who regard their identity as ‘white’ and an important part of their identity, future white American political preferences will be molded by group status threat as well as opposition to diversity. Trump has ‘tapped into’ the demographic of white Americans who feel looked down on in their own home country from mass immigration from the South (and soon from MENA countries). White Americans who feel that their numerical advantage is threatened are more likely to vote for Trump and support anti-immigration policies that will begin to benefit American whites.

It is, however, important to note that Trump may not be who he says he is (like most politicians). On election night last month I blogged on Donald Trump and Ethnic Genetic Interests. I showed that contrary to the average perception of him, his interests lie with Israel, not with his own racial group (due to his children marrying Jews). Moreover, he has already reneged on his wall, deporting illegals and his supposed moratorium on Muslim immigration into the US from threat countries. If anything, Trump is just a stepping stone towards more nationalistic attitudes in the US for whites. With the increased diversity, whites will start to see that they are becoming replaced by other ethnies and in whites with high racial identity, it will trigger nationalistic attitudes and responses to the impending threat on their unique genetic code. This will help to foster the awakening of more whites to identity politics, voting in their own ethnic interests and not for the interest of other ethnies.

I personally hope this leads to a renaissance of race-realism in America, but I may be aiming the bar too high. The conclusion of this study is hopeful for the status of whites in America, however. The more whites that get exposed to diversity AND have high racial identity will then lean more towards Trumpian policies. As whites decrease in number in the US, more and more whites will begin to vote for themselves and, in my opinion, once these nationalistic attitudes appear in the white consciousness in America, this demographic replacement can begin to be reversed. If it were not for the increased immigration, however, this would not have happened. The increased immigration is a main driver of these feelings towards political correctness and anti-immigration. The more anti-white sentiment that is heard in America, the more whites high in racial identity will move towards the right while leftists will continue to commit ‘ethnic suicide’.

The takeaway from this paper is this: Whites exposed to the racial shift high in racial identity were more likely to support Trump, anti-immigration policies and be anti-PC. Whites in the racial shift condition who showed low racial identity showed the opposite and were more likely to vote for Democratic candidates. This paper shows good news in the future for whites in America and voting in their interests. Whites in America are beginning to vote for their ethnic genetic interests and this is largely due to genetic similarity theory as immigration from MENA countries and South of the border increase into America. Moreover, with Trump’s allegiance to Israel, Trump is just a man to awaken more people to the realities of immigration. So Trump himself won’t do anything, but his anti-immigration rhetoric is having people notice the realities of immigration and ethnic replacement in America.

RIP Rushton and Jensen

2050 words

Today is the 4th anniversary of Jensen’s death, with the 4th anniversary of Rushton’s being three weeks ago on October 2nd. The fact that two of the biggest names in the IQ game, and race science game died in a 3-week span was crushing to the truth. When they were pushing their theories on racial differences in intelligence, they had their classes stormed in on and they pretty much couldn’t teach. All of this, in a country where so-called ‘freedom of speech exists’, we can have people shout others down when they speak uncomfortable truths when they don’t like what they’re hearing. BUT, just because those truths don’t want to be heard does not change the reality of them. Rushton and Jensen were pretty much explaining why black Americans have less academic achievement over whites. But when a genetic explanation is brought up instead of the Left’s want for there to be a fully environmental, ‘racism’ explanation they storm classrooms and protest against the so-called ‘fascists’ who are just reporting what they find.

In Rushton’s article The New Enemies of Evolutionary Sciencehe extensively talks about the derision he faced from students while he gave his lectures. It was so bad that he couldn’t teach:

Behind the scenes, however, I became the target of a witch hunt by some of the administrators. Dismayingly, my dean, a physical anthropologist, publicly declared that I had lost my scientific credibility and spearheaded an attack on me in the newspapers. She issued a series of preemptive statements making plain her negative opinion of me and my work. “What evidence is there for this ranked ordering of the evolution of the human races?” she wrote. “None.” Claiming that her views represented only her academic opinion she emphasized that she was not speaking in any administrative capacity. Her letter was nonetheless widely interpreted in the media as a refutation by my “boss.” Henceforth, in order to support me, a person would now have to go up against the dean in addition to prevailing opinion. Next, the chair of my department gave me an annual performance rating of “unsatisfactory” citing my “insensitivity.” This was a remarkable turnaround because it occurred for the same year in which I had been made a Fellow of the prestigious John Simon Guggenheim Foundation. My previous twelve years of annual ratings had been “good” or “excellent.” Indeed, my earlier non-controversial work had made me one of the most cited scholars at my university.

Some radical and black students mobilized and held rallies, even bringing in a member of the African National Congress to denounce me. In one demonstration, a mob of 40 people stormed through the psychology department, banging on walls and doors, bellowing slogans through bull horns, drawing swastikas on the walls, and writing on my door “Racists Pig Live Here.”

The administration responded by barring me from the classroom and ordering me to lecture by videotape on the pretext that they could not protect me from the lawlessness of students. Again I launched formal grievances. After a term of enforced teaching by videotape, I won the right to resume teaching in person, though then I was required to run a gauntlet of demonstrators shouting protests and threats. Only after several forced cancellations of my classes did the administration warn the demonstrators that further action would lead to suspension and legal action. That brought the protests to a halt.

This sounds just like today huh? Seems like much hasn’t changed in the past 30 years. The amount of derision that Rushton faced just for his areas of research interest speaks volumes. Clearly, people are scared of the truth about human nature, whether individually or racially/ethnically. The fact that Rushton couldn’t teach because his classes kept getting interrupted shows that people don’t care about factual data, especially when it hurts their feelings or conflicts with any type of egalitarian nonsense they have in their heads. Once challenged, they get mad, scream ‘racist’ and simply do anything in their power to make life a living hell for the person who dares to speak non-politically correct things. But, and a huge but, just because one stops, for the time being, this from being spoken of, DOES NOT make the racial differences between groups go away. People look for any and all types of environmental explanations to attempt to explain away racial IQ gaps and other racial differences both physically and mentally, but they don’t hold up to the genetic explanation, which was shouted down by people who don’t want their fragile reality broken.

The same thing, of course, happened to Arthur Jensen:

In the 1990s protesters in London pelted him with tomatoes at a lecture hall. “Jensenism” became a term of rebuke, used against those who championed theories about whites’ superiority. “Jensenism,” evolutionary biologist Stephen Jay Gould once declared, rested “on a rotten edifice.”

Arthur Jensen recalls some of these ‘protests’ with AmRen’s Jared Taylor back in 1992:

AR: Well, the sorts of things that you’ve been telling me, the sorts of things you’ve been doing research about, can you and do you freely teach these things in your classes?

Jensen: I sure do. I soft-pedaled things 20 years ago, and even then, there were great protests. I had students who would drop the course if these things were brought up even in a very mild way, in a hypothetical way. Students today wonder what all the shouting was about.

AR: Is that so?

Jensen: Yes, it’s rather hard to get students to believe that there were these protests and so on. They take a lot of this for granted. Oh, there’s been a great change in the students in that respect … But even in 1969-1970, I never saw a black in any of these demonstrations.

AR: Is that right?

Jensen: Not a one.

AR: They were SDS [Students for a Democratic Society]-types?

Jensen: All SDS and Progressive Labor Party, mainly. I tried to put them out when they tried to audit my course, because they were hecklers, and so some of the SDS people would sign up for the course. Of course, then they’d have to do the assignments and take the exams.

Interestingly enough, they usually were the top students in the course because they did so much outside reading to try and give me a bad time. They would go out and read everything Galton wrote! They were bright students. They just happened to be political radicals. “

Years ago, if I gave talks at the APA or the American Educational Research Association, the least little thing you’d say, people would get up on the floor and start denouncing you. I haven’t run into that for a long time, except in Canada and Australia. There’s about a ten year cultural lag in those places, I think, on this topic.

AR: I guess nowadays, as compared to fifteen or twenty years ago, you’re not a notorious presence on campus? People don’t say, “There goes Jensen!” You just don’t get that anymore?

Jensen: No, no. I used to. I used to have to be accompanied around campus by two campus policemen. In fact, they told me not to leave my office and go to the library, or any place, except to go to the men’s room around the corner, but not anywhere else without calling the campus police. They’d whiz across campus in a car and they’d be here in just a couple of minutes and walk with me wherever I wanted to go. One year I had two campus policemen, plain clothes men, in all my classes. They audited my courses.

He had to be escorted around campus by two campus police, all because of his research areas of interest. Why did Jensen have to be protected by two men in plain clothes just for talking about his scientific research? There is a clue in what he said: the Students for a Democratic Society (SDS) and the Labor Party, not coincidentally, leftists who like to censor free, true speech when it doesn’t match to their false views of egalitarianism. But as we know, just because the causes for racial differences aren’t spoken of, that doesn’t mean that they go away. Is race a causal factor in intelligence? Yes, it is. ‘Discrimination’,  a so-called ‘stereotype threat’ is not the cause for lower black intelligence. Rushton and Jensen showed that the races differ by 1.2 SDs at the most, and that it was 80 percent genetic in nature (Rushton and Jensen, 2005: 279). Were the public to accept truths such as this and not any false ‘truths’ such as what the left puts out, Rushton and Jensen would not have received the derision they did when they were publishing and pushing their theories decades ago. I recall a specific poster that I saw on AmRen a few years back talking about how Jensen was a ‘racist’ and along with Shockley, both needed to be fired and lose their jobs because they just so happened to speak these uncomfortable truths.

Here is a Satoshi Kanazawa article he published a week after Rushton’s death:

When I met Phil in person for the first time the following year, I could not believe that a man so intensely hated in public (nearly always by idiots who did not know him personally and who did not know anything about science) could be so gentle, genial, and generous in person.  His very kind and mild manners always impressed me, especially in stark contrast to how people thought and assumed he was.

There is one very small consolation in Phil’s tragically early death:  Phil was not an artist, he was a scientist.  When an artist dies, his art dies with him, which is why there has not been (and will never be) Beethoven’s 10th Symphony or Guernica II.  Unlike art, however, science is cumulative.  The rest of us can honor his memory and his scientific legacy by continuing his work.  Phil was simultaneously a tremendous role model and a very tough act to follow.  He was a model of scientific integrity.  Unlike Galileo, he never recanted.

Science is cumulative. He, Jensen, Murray, Herrnstein, Gottfredson, Lynn et al are Modern Day Galileos. They spoke out against this leftist paradigm that has persisted in universities for decades, and even while shown extreme derision, they never recant their statements because they know they are just speaking the truth. Any allegations of so-called ‘racism’ are just that: allegations with no factual backing behind them. The fact that they need to be called childish words such as ‘racist’ and they need to have their lectures and classes interrupted by ‘protests’ speaks volumes on the research they were doing. The fact that the left has nothing to say except untrue vitriol shows who was right. When you have to attempt to silence someone because you don’t like what they’re saying or it ‘offends you’, that says volumes about your character than the one’s character you’re trying to spew vitriol at.

The fact of the matter is, no matter what anyone or any entity does to attempt to hide racial differences in intelligence, or any other trait for that matter, the truth will always come out. When answers one receives don’t line up to what one sees in his day-to-day life, one goes and looks for the truth. And that truth is that some races aren’t as intelligent as others which leads to differences in scholastic achievement and life success. These differences persist through the generations and when a downtrodden individual (no matter the race) realizes that those have a better social standing then they, they make mental leaps in their head that ‘they’re being held down’ or ‘the man is out to get them’ not even thinking that it’s their own innate ability that’s holding them down in comparison to the other group.

Rushton and Jensen will be fully vindicated one day. It’s only a matter of time. David Piffer showed that IQ alleles differ in frequency between races, meaning that a FULL vindication of Rushton, Jensen, Gottfredson, Murray, Herrnstein, Lynn, Kanazawa et al are going to come soon.

RIP to two great men who had a huge effect on my worldview and the reasons for differences around the world. I only hope that others rise up to continue their work and prove, once and for all, that they were right.

Myopia, IQ, and Race

1200 words

We’ve all heard of the nerd stereotype. One of the main ones is that nerds wear glasses. However, as most of my readers may know, stereotypes are based on fact more often than not. From the black criminal and sprinter, to the hyper-intelligent East Asian, to the intelligent and creative Europeans, we see that these so-called ‘stereotypes’ arise because stereotypes are actually average traits. Therefore, this ‘nerd stereotype’ that they always wear glasses is based on averages, so there must be a genetic component behind it. In this article I will talk about the genetics of myopia, reasons why researchers believe it arises, and racial differences in the prevalence of myopia.

Myopia, better known as nearsightedness, has a pleiotropic relationship with intelligence. Pleiotropy is the single gene or set of genes controlling multiple, possibly unrelated, phenotypic traits. So if the two traits are correlated, then there is a good chance that if one wears glasses they may have higher average intelligence.

Rosner and Belkin (1987) found that the prevalence of myopia was higher in more intelligent and educated groups. They found a strong association between the rate of myopia, years of schooling and intelligence level. Schooling and intelligence weigh equally with myopia, showing that those who are myopic tend to stay in school longer and are more intelligent than average.

Saw et al (2004) show that there may be similar genes associated with eye growth or size (myopia) and neocortical size (*possibly* correlated with IQ, we know it is). This is exactly what Cohn, Cohn, and Jensen found in 1987; that there was a pleiotropic relationship between IQ and myopia. One set of genes controls one or multiple phenotypic traits. They also say that nonverbal IQ is correlated with myopia in the Singaporean cohort independent of near work from the children (such as reading). Nonverbal IQ may be an independent risk factor of myopia independent of books read per week. They conclude that more research needs to be taken out to untangle the cause and effect of the myopia/intelligence/reading relationship.

Mirashi et al (2014) show in a sample of 4600 myopia-inflicted Germans between the ages of 35 and 74 that about 53 percent of the sample had graduated from college compared to 24 percent of the sample who didn’t go to school past high school. They, too, conclude that higher levels of myopia are associated with higher educational achievement and post-school professional achievement and that those who were myopic had higher levels of educational achievement than those in the sample who weren’t myopic.

More recently, Verma and Verma (2015) state that there is evidence that both genetic and environmental factors play a role in the prevalence of myopia. Moreover, Czepida, Lodykowska, and Czepita (2008) come to the same conclusion; that children with myopia have higher IQs and was verified in other countries (the USA, the Czech Republic, Denmark, Israel, New Zealand).

The correlation between myopia and IQ is between .2 and .25 (Jensen, 1998 b; 149). Jensen writes on page 150:

. . .the degree of myopia was measured as a continuous variable (refraction error) by means of optical techniques in a group of sixty adolescents selected only for high IQs (Raven matrices) and their less gifted full siblings, who averaged fourteen IQ points lower, a difference equivalent to 0.92o. The high-IQ subjects differed significantly from their lower-IQ siblings in myopia by an average of 0.39a on the measure of refraction error.1161 In other words, since there is a within-families correlation between myopia and IQ, the relationship is intrinsic. However, it is hard to think of any directly functional relationship between myopia and IQ. The data are most consistent with there being a pleiotropic relationship. The causal pathway through which the genetic factor that causes myopia also to some extent elevates g (or vice versa) is unknown. Because the within-family relationship of myopia and IQ was found with Raven’s matrices, which in factor analyses is found to have nearly all of its common factor variance on g ,n it leaves virtually no doubt that the IQ score in this case represents g almost exclusively. (emphasis his)

Therefore, as noted earlier, we would see a slight variation in the general population between those with high IQs and those who wear glasses and are myopic.

Jensen also talks about race and myopia. He says that Asians have the highest rates of myopia, while blacks have the lowest rate and whites have a rate slightly higher than blacks.

In a tribute to Arthur Jensen, edited by Helmuth Nyborg, it states that East Asians have the highest rates of myopia, with blacks having the lowest rate and whites being intermediate (Rushton’s Rule of Three).  Ashkenazi Jews have a rate of myopia two times higher than that of gentiles, on par with East Asians. These are yet other biological correlates with the g factor that also lend credence to the hereditarian hypothesis.

Glassescrafter.com also shows that East Asians have a higher rate of myopia with blacks having a lower rate:

Certain types of visual disturbances affect some races more frequently. Asian-Americans, for example, are more likely to be near-sighted than Caucasians or African-Americans. African-Americans have the lowest incidence of near-sightedness, but are more prone to cataracts and some other eye diseases. Eye problems, including the need to wear glasses, also can run in families.

Of course, if myopia is a pleiotropic trait (there is good evidence that there is), and wearing glasses runs in families as well as high intelligence, it can be safely hypothesized that the two indeed do have a relationship with each other. The biological correlates show enough that these traits, too, follow Rushton’s Rule.

Finally, Au, Tay and Kim (1993) present data that shows the prevalence and severity of myopia is associated with higher education. They also report on data that Rosner and Belkin reported the prevalence of myopia in males with and IQ of 80 or less was 8 percent while the rate increased up to 27.3 among those with an IQ of 128 or higher. Reported separately, it was concluded that the myopia rates in the cohort of 110,236 young Singaporean males correlated with race (Au, Tay, and Lim, 1993). The myopia rate for the Chinese was 48.5 (IQ 105), for Eurasians it was 34.7, for Indians it was 30.4 (IQ 82), and for Malays it was 24.5 (IQ 92). It’s worth noting that India’s IQ is depressed by disease and bad nutrition, and if this were to be ratified their IQ would be around 94. So this, again, shows the biological correlate with IQ and myopia as it’s showing on the Indians’ genotype.

The association between myopia and intelligence isn’t definite yet, however with more studies looking into the relationship between these variables I believe it will be concrete that those who are more myopic tend to have higher IQs due to the pleiotropic nature of IQ and myopia. Since reading is heritablethose with higher IQs as children tend to read more as adults, and the racial gradient is noticed in children, it’s pretty safe to say that myopia and IQ are linked pleiotropically and give more credence to the hereditarian hypothesis. Most studies find a statisically positive correlation between myopia and intelligence. Along with the racial disparities in myopia as well as intelligence, it’s pretty safe to say that the relationship is genetic and pleiotropic in nature since the races also differ in these variables.

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.
