𧡠Intelligence Variance Heritability
Anonymous at Mon, 17 Feb 2025 21:47:28 UTC No. 16589572
Since studies on monozygotic twins and studies on adoptive parents have clearly shown that general intelligence variance is primarily determined by genetics, why do so many sociologists still unduly question the role of genetics?

Well the result of over 100 years of testing and intense study tells us that intelligence if 60-89% heritable with the heritability increasing with age meaning thta the older we get the more our genes dictate the expression of our abilities compared to our contemporaries.
And out of the entire field of psychology (lol) the subset known as psychometircs and especially that pertaining to intelligennce research has the highest replicability

The definition of heritability is given here
https://en.wikipedia.org/wiki/Herit
It states that [math] P = G + E [/math], where P is the trait that can be measured experimentally like IQ test scores and G is the genetic effect on P and E is the environmental effect. This equation is the basis of all calculations of heritability in things like twin studies. Now anyone with even a middle school knowledge of mathematics can tell you that there is literally no reason for such an equation to hold because in general P will be a complicated function P(G, E). Just think about it - even if IQ score is considered a measure of intelligence, how do you know that IQ is equal to the sum of G and E rather than IQ^2 or 10^IQ or any other of the infinitely many possibilities? Indeed, how do you even know if any measure of intelligence can be written as such a sum? When this assumption is questioned, the entire industry of heritability calculation falls apart and is revealed to be nothing more than a pseudoscientific numerology.
Anonymous at Wed, 19 Feb 2025 00:41:24 UTC No. 16590929
That formula is a statistical model used to approximate the variance in a population, not an absolute law. And it's backed up by mountains of real world data.
That real world data supports additive models, not your IQ^2 retardation.
>Indeed, how do you even know if any measure of intelligence can be written as such a sum?
Because the data from various twin studies, adoption studies and GWAS fits the assumption...

P = G + E is indeed a simplification but a reasonable one. The validity of a scientific theory is in its predictive power. Just to give one example Steve Jobs biological relatives are all quite accomplished, despite very different environments (including growing up in poverty like his daughter Lisa), while his adoptive relatives are unexceptional. This is just an example among many. There are numerous studies on adoptive children and they all show the same thing: IQ is more correlated to that of their biological parents than with that of their adoptive parents. Blank statism cannot account for this. You can complicate P = G + E, grasp at straws all you want, but the harsh reality is that genes count. I'd like to point out, before getting accused of waaaaahhhcism that I don't like this state of affairs. In fact blank statism was, more or less, the worldview I was given as a child. The realization that genes were so fundamental was quite shocking, and not in a good way as I didn't like the implications at all. Unfortunately the data points overwhelmingly in one direction. It's nobody's fault, nature is a bitch and all that.

There is plenty of evidence in literature for the heritability of IQ, some of it was linked in this thread. It's not even a topic of debate outside the social """"sciences"""".
A word of advice, kid. People are fed up with your kind of shit. Really, really fed up. I've known insufferable faggots like you in real life. You just won't accept evidence if it goes against your ideology. By not accepting the scientifically backed answers other people give you, you "win" by default. The thing you don't understand is that your behaviour does not result in ACTUAL winning. Millions of people like you, behaving like you do, is the main reason Donald Trump won the last election. Millions of people, even in academia, denying the biological reality of sex, have permanently jaded a lot of people, even on the left. And now Donald Trump is in the White House and wants to rape academia (we can only hope). Are you happy with this result?

Look up the twin studies dealing with IQ. They describe their methodoligy in depth.
What do you believe produces intelligent thought in a given human? Is it the brain or something else? Because if you believe that our thoughts are products of our physical bodies, then of course variance in cognitive ability depends on genes. Then we are just quibbling over whether or not the genes for intelligence are spread evenly across all of humanity. Which would be almost impossible. Why would the cold asiatic planes produce the same genetic outcomes as the african jungles in regards to IQ but nothing else in humans?

No, the question is how much of the influence to attribute to the environment vs how much to genes. Keep up.

Wrong, you have no idea about how any of this works, because you're mathematically illiterate. The heritability is a calculation made using some observed data. There's no fitting anything here. It's just assuming that the data fits the model (particularly the dumbest possible model) and then using that to calculate the "heritability", when in fact there is no reason to think that this number has anything to do with any heritability at all.

I skimmed through the first chapter where they try and fail to define heritability, so I stopped reading. Their definition fails because of the reason I already gave in >>16590901. Specifically, their claim in page 21 that the variance in the phenotype [math] P [/math] can be split up as [math] V_P = V_G + V_E + V_I + 2 \text{Cov}(G, E) [/math] is already unjustified (I included the factor of two to correct their typo), since there is no reason for such an equation to hold when [math] P = P(G, E) [/math] for even a slightly complicated function P. Of course, you could simply try to define [math] V_I [/math] as [math] V_P - V_G - V_E - 2 \text{Cov}(G, E) [/math] or something, but that would have no scientific meaning since [math] V_I [/math] couldn't even be interpreted as a variance of some variable anymore - it's not even guaranteed to be non-negative and it would be impossible to measure without already knowing [math] V_G, V_E [/math] beforehand. The way they split up [math] V_G, V_E [/math] further as a sum of different types of variances is unjustified for the same reason. This means that the equation is ill-defined and as a consequence their notion of heritability is also ill-defined and the rest of the book might as well be fiction. To their credit, they do mention the various discontents of serious scientists with trying to measure heritability, so if you want to look up these criticisms by others, the book might help lol.

Yes. We want Vedic era India, not modern India after it has been corrupted by centuries of exploitative British colonialism, which themselves were preceded by centuries of Islamic rule, which in turn were preceded by centuries of intermixing between the Indo-Aryan settlers and the earlier Dravidian populations of the Indian subcontinent. In the times of Ancient Greece and prior, the Indians were some of the most intellectually and culturally advanced people on earth - and they also would have been much whiter. India when it was ruled by the ancient Indo-Aryans was a great civilization, and it relied on a caste system to protect it's elite human capital (i.e. the white who migrated there from the Pontic-Caspian steppe in modern Russia and Ukraine).
