The crime-genius connection in extreme IQ men

The biographies of 280 scientists indicate that the distribution of their age at the time of their greatest scientific contributions in their careers (age–genius curve) is similar to the age distribution of criminals (age–crime curve). The age–genius curves among jazz musicians, painters and authors are also similar to the age–crime curve. Further, marriage has a strong desistance effect on both crime and genius. I argue that this is because both crime and genius stem from men’s evolved psychological mechanism which compels them to be highly competitive in early adulthood but “turns off” when they get married and have children. Fluctuating levels of testosterone, which decreases when men get married and have children, can provide the biochemical microfoundation for this psychological mechanism. If crime and genius have the same underlying cause, then it is unlikely that social control theory (or any other theory specific to criminal behavior) can explain why men commit crimes and why they desist.

the same underlying cause being extremes of IQ

volatile extremes

obviously they’re not the bloody same

But yes, marriage has a good effect on some people. And?

Should we reward criminals with breeding and punish genius genes?

Tesla’s highest achievement we know was done before aged 30. Clearly, something isn’t right here.

Makes more sense as a sexual selection strategy to attract a mate.

High IQ – prosocial.

Low IQ – antisocial.

General intelligence, Emotional Intelligence, leadership

Emphasizing the importance of cross-border effectiveness in the contemporary globalized world, we propose that cultural intelligence—the leadership capability to manage effectively in culturally diverse settings—is a critical leadership competency for those with cross-border responsibilities. We tested this hypothesis with multisource data, including multiple intelligences, in a sample of 126 Swiss military officers with both domestic and cross-border leadership responsibilities. Results supported our predictions:

(1) general intelligence predicted both domestic and cross-border leadership effectiveness;

(2) emotional intelligence was a stronger predictor of domestic leadership effectiveness, and

(3) cultural intelligence was a stronger predictor of cross-border leadership effectiveness. Overall, results show the value of cultural intelligence as a critical leadership competency in today’s globalized world.

EI and EQ, so girly, right? What bullshit.

Smarter people are still smart once they leave their magic dirt, really?

Are kids of teenage mothers dumber?

The creeps are wrong again.

Teenage motherhood has been associated with a wide variety of negative offspring outcomes including poorer cognitive development. In the context of limitations of previous research, this paper assesses the contemporary relevance of this finding. In this study we investigate the long-term cognitive status (IQ) among 21 year adult offspring born to teenage parents using the Mater University Study of Pregnancy- a prospective birth cohort study, which recruited all pregnant mothers attending a large obstetrical hospital in Brisbane, Australia, from 1981 to 1983. The analyses were restricted to a sub-sample of 2643 mother-offspring pair. Offspring IQ was measured using the Peabody Picture Vocabulary Test at 21 year. Parental age was reported at first clinic visit. Offspring born to teenage mothers (<20 years) have -3.0 (95% Confidence Interval (CI): -4.3, -1.8) points lower IQ compared to children born to mothers ≥20 years and were more likely to have a low IQ (Odds Ratio (OR) 1.7; 95% CI: 1.3, 2.3). Adjustment for a range of confounding and mediating factors including parental socioeconomic status, maternal IQ, maternal smoking and binge drinking in pregnancy, birthweight, breastfeeding and parenting style attenuates the association, though the effect remains statistically significant (-1.4 IQ points; 95% CI: -2.8,-0.1). Similarly the risk of offspring having low IQ remained marginally significantly higher in those born to teenage mothers (OR 1.3; 95% CI: 1.0, 1.9).

In contrast, teenage fatherhood is not associated with adult offspring IQ, when adjusted for maternal age. Although the reduction in IQ is quantitatively small, it is indicative of neurodevelopmental disadvantage experienced by the young adult offspring of teenage mothers. Our results suggest that public policy initiatives should be targeted not only at delaying childbearing in the population but also at supporting early life condition of children born to teenage mothers to minimize the risk for disadvantageous outcomes of the next generation.

 The small but significant decrease in offspring IQ combined with other challenges often faced by children of teenage mothers may contribute to increased risk of poor educational performance and intergenerational transfer of psychosocial and health disadvantage.

The smarter atheist myth

No! People on reddit lie!?

The myth of the smarter Atheist

What we see is a fairly weak relationship between national religiosity and average national IQ. Once we get up to about 20% of the population being Atheist, the IQ of the population flatlines at around 100 from then on. Even worse, in the ~0% Atheist range, there’s a wide range of national IQs from 64 to 100+ — with a cluster of low-IQ nations that appear to be driving the “trend.”

Indeed, if we look at income per capita instead of religiosity, we already see a much better correlation with average IQ. The correlation between religiosity and IQ is too weak to suggest that religiosity predicts intelligence on the national level. Anyone who claims otherwise is grasping at straws.

You could study it..

Religions and IQs driving that aren’t all the same uniformly across the planet.

Just look at the West? No?

 I created a less misleading version of Kanazawa’s plot below; judge the data for yourself.

Religious people are less likely to attend college, where tests are taken…

The most religious adults had an average IQ of 97.14, whereas the atheist adults had an average IQ of 103.09. That may seem like a wide gap — 6 whole IQ points — until we remember that anyone in the IQ range of 90-109 is classified as having “average intelligence.”

Yeah, it’s a bigger gap than same-race gender, at least?

Under two points, you must be so proud. What measurement error?

So really, all Kanazawa showed is that the average person has average intelligence regardless of how religious they are.

How Cognitive Genetic Factors Influence Fertility Outcomes: A Mediational SEM Analysis

Utilizing a newly released cognitive Polygenic Score (PGS) from Wave IV of Add Health (n = 1,886), structural equation models (SEMs) examining the relationship between PGS and fertility (which is approximately 50% complete in the present sample), employing measures of verbal IQ and educational attainment as potential mediators, were estimated. The results of indirect pathway models revealed that verbal IQ mediates the positive relationship between PGS and educational attainment, and educational attainment in turn mediates the negative relationship between verbal IQ and a latent fertility measure. The direct path from PGS to fertility was non-significant. The model was robust to controlling for age, sex, and race; furthermore, the results of a multigroup SEM revealed no significant differences in the estimated path coeficients across sex. These results indicate that those predisposed towards higher verbal IQ by virtue of higher PGS values are also predisposed towards trading fertility against time spent in education, which contributes to those with higher PGS values producing fewer offspring at this stage in their life course.

Jews score higher on verbal IQ….

Divorce risk x IQ

Don’t marry the bimbo.

Should also look at spousal IQ disparity.

Presumably, bigger = higher % divorce.

In ‘The Bell Curve: Intelligence and Class Structure in American Life’, Herrnstein and Murray reported a negative relation between intelligence and divorce risks. This article analyses the relationship between intelligence and divorce risks for two different Dutch cohorts, for which data on their intelligence measured during their childhood, are available. A positive relation between intelligence and divorce risk is found for the Dutch fifty-year-olds born around 1940. Among this older cohort, divorced respondents have a higher mean intelligence score than respondents who stayed together with their spouses. However, a negative relation between intelligence and divorce risk is found for the Dutch thirty-year-olds born around 1958. Among this younger cohort, divorced respondents have a lower mean intelligence than respondents who stayed together. A possible explanation of the shift is that the democratisation of divorce over time has altered the nature of divorce from a highly selective to a more normal event.

Or r-types stopped marrying as much, from pressure. Therefore, fewer divorces.

Link: IQ and corruption

Throwing this here.

and the spread is nice and geographical — west to east/north to south: the anglos and the dutch (and are the scandinavians there? i can’t tell), my long-term outbreeders, are the least corrupt — then, working upwards on the chart (i.e. towards more corrupt) you’ve got the belgians and french and spanish — crossing the line into the more corrupt zone you start to have poland and hungary and the czech republic, places on the border of the hajnal line and the medieval outbreeding project — and then you get up to italy and the ukraine and russia.

east asia is, of course, interesting with singapore, hong kong, and japan being some of the least corrupt, and china being way up by corrupt italy. need to work on figuring out east asia one of these days! (~_^)

Nobody looks at Asia.

We know about Africa and Europe, we all know at this point. For about a century, we have known.

The interesting thing now is Asia/Europe. Are you all too scared to look?

Look at voting patterns, this is important.

so, there’s definitely a connection between intelligence and corruption, but that’s not the whole story, otherwise china and russia and italy and korea wouldn’t be very corrupt at all.

maybe their IQ scores are as real as their college transcripts?

“How an industry helps Chinese students cheat their way into and through U.S. colleges”

Muh model minority.

Cheating is illegal BTW. It’s fraud and theft from the worthy applicants who lost out (zero sum).

Teachers help too: racketeering.

one thing that the chinese, russians, and italians have in common (don’t know much about the koreans) is a longer history of inbreeding as compared to the english and the dutch (see mating patterns series below ↓ in left-hand column). the awesome epigone did find a correlation (0.44) between consanguinity and corruption, but like i said then, i’m betting that the correlation would be stronger if we could calculate something like degree+length-of-time inbreeding.

All trader nations. Merchants. Former merchant empires.

Brain size of males by race

includes this

The third piece of evidence is that the racial gaps have existed for a long time. In fact, based on the data from the tables above, the White/Black brain size gap doesn’t seem to have gotten any smaller during the 20th century.

Long before your 60s immigration acts.

The first thing to note is that brain size in the general population has a heritability of 87%. Thus, almost all the differences between individuals in brain size are caused by genes.

Secondly, we should note that racial brain size differences are present at, and even before, birth.

Keep blaming women though, that’ll help.

We need more direct studies like this. Gestation length and other variables must be accounted.

Menarche and other variables like WHR vary by race in the women too. More studies! MORE!

The manosphere is based on a myth of equalism, it was destined to fail.

Fourthly, racial brain size differences have been found all around the world. For instance, the Beals and Smith data set previously referred to features skulls from over 100 populations world wide. Many of the autopsy studies previously cited were done in East Asia, as were two of the MRI studies. This makes any gene independent cultural explanation less likely.

Fifthly, several studies have shown that mulattoes have an average brain size in between that of Blacks and Whites (Pearl, 1934Bean, 1906). This finding has been established on multiple occasions and is what a hereditarian hypothesis would predict since mulattoes are half White and half Black genetically speaking.

Do studies for other mixes.

Sixth, many traits which tend to co-evolve with larger brains also differ racially in a way that mirrors the body size adjusted brain size patternRushton and Rushton (2003) looked at 37 anatomical features which 3 textbooks on human evolution identified as tending to co-evolve in the hominid line with larger brains. For instance, larger pelvic size tends to co-evolve with brain size so that mothers can give birth to larger brained infants.  Rushton then utilized 5 forensic anthropology textbooks to look at racial differences in these traits. These traits followed the East Asian>White>Black pattern in 25 out of 31 cases. The probability of this happening at random is .000000001.

WHR is important.

Follow the tag, there are racial differences in studies.

And East-Asian isn’t a race, at best it’s a sub-group, do more studies. Properly.
Asians fail more often on IVF, also posted about that.

Similarly, Rushton (2004) showed that, across 234 mammalian species, brain size correlates with longevity, gestation time, birth weight, litter size, age of first mating, body weight, and body length. Various studies have shown that each of these variables also differ between the races in a way that, based on what we find across the animal kingdom, would predict the body size corrected brain size differences we observe (Rushton, 1995Templer 2006Rushton and Templer, 2009;).

Longevity – must look at averages e.g. not Danes for all whites nor Japs for all Asians.
Gestation – we know this varies.
Weight – control confounds.
Litter size – look at natural rate of twinning.
Virginity loss is r-select, do not want.
Body weight – vague.
Length – we already know racial height. Still, add to the rest, I guess.

Thus, we have six lines of evidence all of which would be predicted by a hereditarian view on racial differences in brain size. While each line of evidence on its own may not be compelling, the combination of all six seems to strongly imply that racial brain size gaps are partly heritable.

It is worth noting that the racial brain size gaps are probably not entirely attributable to genes. Some authors, including Richard Nisbett, have plausibly argued that nutrition also plays a role. However, there explanations are not mutually exclusive, no environmental variables has been shown to account for the majority of the gap, and,  as we have seen, there are many separate lines of evidence indicating that genes also play a role

A confound, in weight.

I suggest seafood consumption.

There is good evidence that the races evolved different brain sizes in response to climate. Specifically, various studies have found that a population’s brain size correlates with climate related variables. For instance, Pearce and Dunbar (2011) ‘s data set produces a correlation of .74 between a population’s brain size and its latitude. Similarly, Ash and Gallup (2007) found a correlation of .48 between the size of 109 fossilized human skulls and the latitude at which they were found. Further still, Bailey and Geary (2009) analyzed 175 skulls ranging in age from 10,000 years old to 1.9 million years old and found a correlation of -.41 between brain size and winter temperature and -.61 between size and latitude (larger brains were found in areas more distant from the equator).

How dare you use science.

The weebs might reee!

Lynn (2015) used Smith and Beals data set of 20,000 skulls from 122 populations to estimate that roughly 30% of the African-European IQ gap can be statistically accounted for by brain size differences. By contrast, brain size differences would actually predict an Asian-European IQ gap 35% larger than the one that actually exists. Thus, brain size is probably one of many factors, both biological and environmental, which account for racial intelligence differences.

Can ya rig the test?

Easy, who’s the most innovative?

Especially before colonialism spreading info. Right?

You can rig IQ tests and college transcripts, not more advanced farming equipment when the other group invented it centuries prior.
