Are there any separated twin studies to show what percent of IQ is cultural and what is genetic?

I don't have sources, and the french IQ test may be different from yours, you can artificialy inflate your IQ result just by taking more and more IQ tests and memorizing solutions

There are a ton, Alternative Hypothesis made a ton of Videos about that.

in short: Its highly heritable. And Enviroment doesn't play a too big role in it.
Or other way around: Enviroment can ruin your potential (ie malnourished, stuff like that). But genetics limit it.

A real IQ test should take into account what you already know, and put you in an unknown problem to solve with logic

and that's not what i experienced...

A few, Joe, but not as many as I'd like.

The results aren't concrete, but it appears to be more than 50 percent nature.

serious business IQ tests are a good 6 hours long and produce 5 different scores in different areas of cognition

IQ tests used in genetic studys are probably not the kind of tests where they just let you take it over an over again

you know, because they actually want to study something

envirnment drives evolution

evolution of inteligence creates organisms with the ability to manipulate the envirnment

thus some degree of human evolution is driven by humans but for much of history this is imperceptive

I guess the next logical question would be if genetics provably has an impact on IQ it would explain the bell curve. However further testing would need to be shown to verify that specific genetic variances linked to race have an impact on IQ. I think the easiest way to prove racial differences is to show statistics around the prevalence of certain genes that have been linked to mental ability among different races.

This sort of test could disprove either theory depending on the outcome so it would be far more valuable than correlation.

I disagree with Arch-Fiend.

High IQ is a result of high population density.

is that the big topic where you're from are is it just out of curiosity ?

( i mean the subject of IQ )

Where do you have the highest IQ? Where the Population was the densest in history...
Where have you low IQ? Where there weren't many people historically.

are -> or sorry

how do you define a high population density?

and are you arguing a direct result or a corrilation?

a corralation may be more likely, a direct result i would want to know how you account for animals with incredibly high birth rate and comparitive population density to dis-similar species and even similar species

```how do you define a high population density?```
Cities for example.

cities are a subpopulation of a population group

```and are you arguing a direct result or a corrilation?```
Direct result because if you don't have money, Woman won't have children with you, so you need to be somewhat successful. To be successful you need relatively high IQ.

And I'm not talking about the last 100 years or so, obviously.

I'M talking about the last 2000 years or so

your making this comparison in a VERY narrow scope of evolution

No, its one of the most important things.
The "alt-right" favors the "Winter Theory".

when you start talking about inteligence you need your thesis to stand up to how humans evolved to even be able to create citys, how the lowest inteligence populations on earth manage to be 4 or 5 times more cognitively effective than the species they decend from, and how many animals in the world have vastly different congnitive capabilitys than others without seemingly much difference between them

Wich means that High IQ is a result of harsh Enviroments (=Winter), wich requires some planning.
And if you messed that up, you'll die

you need to tell me how the difference in inteligence between a crow and a pidgen is as vast as the difference in inteligence between a man and a crow

and your arguement of population density falls appert with the crow and pidgen

or if we just look at ants

No, because Humans are different and not adapted to the enviroments -> No Fur or feathers.

and also need more food because they are bigger.

we are adapted to envirnments
