Besides, this is assuming the IQ gaps are entirely environmental...

non-environmental*

Yeah
But their children will regress to the mean

or mostly so*

@Ed do you know what regress to the mean means?

IQ heritability is the same as height past a certain age

Ed, do you know what regression to the mean means?

@Ed 25 years

of age

> In statistics, regression toward the mean is the phenomenon that arises if a random variable is extreme on its first measurement but closer to the mean or average on its second measurement and if it is extreme on its second measurement but closer to the average on its first.

dats right

you can use it to improve pupils results 🙂

Regression to the mean is a statistical phenomenon where you use the central theorem to fix outliners in your analysis.

@BeautyIsEternal
The probability of a freak accident genius in subsaharan Africa having a son who is also a freak accident genius is lower
Than the probability of him having a son that is closer to the average

No

just let them jump
take the worst
let them jump again
and oh wonder, they wont be the worst again 🙂

some children due to external factors end up smarter than what you would expect by his parents, but by 25 it goes straight to the expected

same with height

You probably did not understand Rushton or whom ever you were watching when he was talking about regression to the mean. Regression to the mean is a mathematically phenomenon.

i was the tallest by far in my school year up until 13, then i fell behind and im average now

That's basically what I said

> The probability of a freak accident genius in subsaharan Africa having a son who is also a freak accident genius is lower
> Than the probability of him having a son that is closer to the average

not the same

clearly

One is genetic. One is mathematically.

propose another term, then

Besides, can't we use eugenics to raise the average IQ of this hypothetical new american ethnicity?

@Big Ben by like 10 generations lmao so nearly 1000 years

sorry

400

We're talking about a mathematical expression of the probability that the child of a high IQ bantu also has a high IQ

Regression to the mean, really as far as I see it, is when geniuses have babies who are normal IQ, which is normal. A genius is a rare combination of genes of personality and IQ that give someone the ability to produce novelty. I do not think it needs term, as it is just basic genetics. We don't have a term for advancing away from the mean, do we? @blanc

> Besides, can't we use eugenics to raise the average IQ of this hypothetical new american ethnicity?
@Big Benif you're smart enough and wise enough to recognise the benefit of eugenics

You're in less need of eugenics than most

Eugenics is never going to happen aways.

It is more likely we will subsidize dysgenics before we do anything eugenic.

It can happen without government enforcement

In certain societies

And we can not take the government over at this point.
