There’s an interesting 2013 meta-analysis by Branigan et al about the heritability of education attainment as measured by twin studies:
Source: Branigan et al, 2013
If you average all the studies in the US and UK, the mean heritability is 0.31.
A recent study of 1.1 million people (largely from the U.K. and U.S.) found polygenic scores predicted 0.12 of the variation in education, or roughly 39% of twin studies’ heritability.
Why so much lower than twin studies? One reason might be that genetic samples suffer from range restriction, since relatively educated people (like our very own G-man!) seem more likely to get genotyped.
I found this quote from the supplemental materials of a 2018 study by Ritchie et al.
A personal measure of socioeconomic status is educational attainment. We compared the distributions of educational attainment in UK Biobank to the data from the 2011 Census for England and Wales (available at the following URL: https://www.nomisweb.co.uk/census/2011; England and Wales makes up the vast majority—around 89%—of the population of the United Kingdom). In the census, for those ages 50+ years, 25.5% of males and 20.5% of females reported having a ‘level 4 qualification’, the category including college/university degrees (we might expect this figure to be slightly higher were it restricted to the 44-77 age group, but that precise age subset was not available from the census data). In the subsample of UK Biobank used here, 48.0% of males and 42.2% of females reported having a college degree. Thus, the sample was not representative in terms of educational attainment: a higher proportion of individuals in general had a degree.
Adjusting for range restriction would perhaps increase the amount of education variance explained by DNA from 0.12 to 0.2 (though that’s just a guess).
0.2 is 65% of the heritability found in twin studies.
Meanwhile twin studies find about a 0.75 heritability for IQ.
That means we might expect polygenic scores to eventually explain 65% of 0.75 of the variance in IQ, or 0.49 at least among whites living in the West.
Of course that might be a huge overestimate of heritability, if much of the genetic variance is not causal (i.e. population stratification, gene environment interaction).
On the other hand it might be a huge underestimate of heritability, if much of the genetic variance in IQ is not capture by the additive effects of common SNPs.
Both possibilities likely cancel each other out to some degree.
But if the heritability of IQ really is 0.49 (one of the fiercest critics of twin studies suggested 0.45) then square rooting the heritability gives a potent 0.7 correlation between DNA and IQ.

”Heritability of education”
Already wrong…
Only potential can be heritable and not achieved given-potential.
the h^2 for IQ from twins raised together are always lower than the few for identical twins raised apart [refacted by pp, sept 7, 2018]
What’s your point? The twin study heritability for education was calculated the same way so IQ is more than twice as heritable education when h^2 is measured the same way
peepee conveniently forgets the 40% diminution in h^2 once population stratification is controlled for.
[redacted by pp, sept 7, 2018]
Your reading comprehension is impaired. I mentioned population stratification & gene-environment interactions might overestimate heritability but failure to capture rare & non-additive genomic variants may underestimate it. It’s a wash.
[redacted by pp, sept 7, 2018] IQ test was 11. her highest was 18.
My lowest wisc-r subtest was the bottom of high average which is +0.6 SD or scaled score 12.
See the chart here:
https://www.epicrehab.com/using-adjectives-to-describe-ability-levels/
whereas peepee’s lowest scores were on the most g-loaded subtests which are NEVER used to diagnose anything and her whole test was given by ONE fellow shitholer at age 12, not age 9.
sad!
(2+9)/(2*3)*15 + 100 = 127.5.
sad!
My lowest scores were on information (culturally biased) and digit span (language biased)
Nonetheless i got a 12 on digit span while you got a 10, though you unconvincingly claim the tester stopped the test as soon as you proved you lacked ADD (unlikely since she wouldn’t have even known until she totalled the points and checked the norms for your age group & because knowing the exact score is also helpful)
My highest scores were at the top of the very superior range ( 19), and unlike you i got more than one 19, suggest ceiling bumping.
Nonetheless if you want to go by highest vs lowest, my medium is 15.5. Your medium is 14.5
On the WISC-R, the mean average scaled score 10 is with an SD of 2.1 so I’d be IQ 139 & you’ld be 132, but deducting a Flynn effect of 7 points (old norms) would bring me down to 132, & bring you down to 125 (below gifted level)
Which may help explain why jimmy stated that i got the better of you on every exchange we’ve ever had & why pincher Martin told you “we both know you’re not that smart.”
7/0.3 = 23 = 1994
1994 – 12 = 1982
I took the WISC-3 in 2000 at age 12 scored 125
18*0.3 = 5.4 = 119
Right Brain = 119
The heritability of IQ increases with age and reaches an asymptote at 18–20 years of age and continues at that level well into adulthood. This phenomenon is known as the Wilson Effect.
in this case IQ IS like height. the tallest kids will be tall as adults but will not be as tall in relative terms as they were as kids. but there is a fixed potential height. swank will never not be a midget. i will never not be incredibly sexy.
people mature physically and intellectually at different rates and at different rates at different ages. but physically maturation ends at some point, at least in terms of the skeleton.
maybe my supposed low SIQ indicates i’m on a less steep trajectory.
adulthood at 18 is a legal fiction. adulthood per se is an ideological fiction. there are old people much less mature than some young people.
the point is i can sing and draw. very talented at both these right brained activities. RIP burt. the greatest laugh of all time.
Has the Wilson effect ever been tested on twins reared apart i wonder.
If IQ really does become more heritable with age, it proves how impotent environment is (since cumulative experience variation increases with age)
…but physically, maturation ends…
i admit that peepee might answer a puzzle on the back of a Cap’n Crunch box one second before i did.
she still wants me inside her.
what peepee doesn’t know is that those people who have called me “the smartest person they’ve ever met” did NOT say this as a result of my test scores or my grades.
they said it after they got to know me. i know this because i said to them, “are you sure about that?” i paraphrase.
no. it’s who you ARE peepee. not what you score.
it’s OBVIOUS.
but it’s also SCARY. and it also engenders ENVY.
lalke was cute. face it.
They were going by your general knowledge & vocab, not your ability to adapt. That’s how most people judge IQ subjectively & it works in most cases since these are extremely g loaded, but g doesn’t apply to people as neuro-atypical as you which is why you were fired from jobs for being slow.
I have a high general knowledge and am slow. People think I am smart. I do think the several 170 people I encountered were very intelligent.
and everyone on the internet thinks peepee is retarded, because…
she IS.
Not true.
I did an anonymous poll & the average person ranks me in the 130s, and steve sailers put me on his blog roll
If i didn’t obsess about Oprah I’d have more credibility. That’s made me a bit of a joke i admit, but i have to follow my passion
it also helped that…
i LOOK smart.
this is NOT exactly the same as being good looking.
aesthetics DON’T LIE.
for example, eliot spitzer LOOKS smart…(even though he’s not a candidate for sexiest man a live and is a TOTAL douche.)
he made a perfect score on the LSAT. that’s 170+ IQ.
austan goolsbee LOOKS smart.
given the dysgenic effects of the industrial revolution and given history peepee must conclude that aryans are the master race.
aryan = indo-europeans and their descendants.
^^^that’s barry says the interwebs. lalke’s dog.^^^
why is barry not reviled?
why is kurt franz worse than barry?
are men so much more responsible and so much less brainwashable than dogs?
that is, a high VIQ is usually USELESS, but it helps in making YUGE fortunes.
Especially if you have high social IQ to go with it (i.e.oprah)
Jews also have high math IQ which also helps become a billionaire
Wait…Math IQ is just a function of VIQ. Working memory, digit span, are all VIQ aspects. If we exclude math IQ from the more spatial aspects of applied math, and only regard the abstract and arithmetic, then yeah, Jews dominate there.
Modern wechsler scales no longer use the verbal vs non-verbal dichotomy
It’s now divided into five domains:
1) verbal comp
2) working memory
3) spatial
4) abstract fluid
5) processing speed
Math would probably correlate best with abstract fluid (i.e. figure weights, matrix reasoning)
“aryan” is a SANSKRIT word!
just like “swastika”.
the VEDAS were written by proto-nazis.
the law of manu
THE NAZIS LOVED INDIANS.
where’s my picture of super sexy lalke?
I know all that mug of pee. I’m half german.
Nazis loved Brahmins because Brahmins were relatively more fairskinned than other Indians, and because Brahmins kept other Indians under their feet using the laws of manu
Well at least Nazis thought that way. All Brahmins were was glorified beggar s of whichever king was in power.
The vedas were allegedly written by indo-aryans. They were aryan ‘ in name only. They were called indo-aryan in modern times to help people differentiate them from Iranians. I doubt they called themselves aryan. Arya word was used by a lot of people in olden times after 1000 B.C to my knowledge, to designate themselves, for various reasons. For eg: Even brahmins used it to call brahmins and other caste as arya if they followed certain religious rituals and called those who didn’t follow them, as non-arya.
Who were the Aryans? Nazis and a lot of prominent white intellectuals regarded Aryans as ancestors to whites, who were all blonde and blue eyed. Only when they arrived in Europe did they meet the filthy Basque and diluted their blood away from the pristine fairness. Or something like that.
To many god-like, blond and blue eyed fantasy whites to keep up with: be it solutreans, hyperboreans, or aryans.
peepee will post a picture of barry but not of kurt.
this is SPECIESISM.
when a woman says her IQ is higher that yours what she really means is…
1. i’m a man hating lesbian…
OR
2. i’m so ugly no man will ever want me but i still want you inside me.
chinaman boss (actually 6’3″ taiwanese immigrant):
we (actuaries) think we’re so smart, but you really are smarter than us.
swarthy midget boss:
you’re scores say you’re smart, but you’re an idiot.
woman boss:
you’re too smart to be an actuary.
peepee can make of this what she will, but whatever she makes of it i am rare.
ADOLF HITLER…
VS.
OPRAH…
HITLER WINS!
Hitler wins on influence. Oprah wins on money.
