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.

Your deadbeat dad made you short

I ain’t playin’ today.

It isn’t muh genetics, it was Daddy’s adultery.
The sins of the father shall be visited etc etc.

If only we were warned in a book of some kind.

Men: parental death and divorce during early childhood was associated with shorter adult height, and later puberty. Later puberty was associated with shorter adult height. Path analyses demonstrated that the relationship between parental divorce and height was completely mediated by age at puberty; although parental death was only partially mediated by age at puberty

The wages of sin. Deadbeats may as well be statistically dead. Actually better.

Good luck blaming the Jews for your Dad’s case of the Wandering Penis.

Most common cause of divorce: adultery.

Most common spouse to cheat: male.

Sure, the wife might file but… vitally, after she’s been publicly humiliated. The Bible says to leave if he won’t do his duty.

If their own father is still sexual competition (coughs in Freud) then logically the son’s body would shut down and delay puberty. Manwhore dads kill their son’s chances, since they’re bad parents. Adultery isn’t just spousal abuse, it’s child abuse. So severe, it gets the death penalty of both guilty parties in Christianity. Better an adulterous husband be dead, for his children’s sake. Health outcomes like this prove it.

The Sexual Revolution made you short… and ironically less successful in it.
