The evidence is out there, tons of studies done on environmental effects on IQ.
Now, I did find that genes can affect IQ a lot... especially in adults.
The extent of this is not well known to me, but the problem lies in racist graphs pushing an agenda of anti-blacks by ignoring all of the environmental evidence.

So we accept there is a genetic factor and a environmental one

Studies agree about 60-80% of IQ is determined by genes once your brain is developed, about 27 years and older.

Its definitely both.

Could you link me to studies

Of course.

That's pretty much the whole discussion, how much percent is genetic

And if it is 60-80%, that would mean some ethnicity are genetically less intelligent on average

This is the article I was reading from a consultant neurosurgeon in India named Arun Oommen.

He linked the percentage evidence to the first link I provided.

Which didn't demonstrate a percent.

Indeed

It looks like theyre trying to identify genes responsible for intelligence

Also 60-80% in adult years is all based on genes. Now what percent of that 60-80 is affected by the changes in ethnicity. That we don't know, and we can't assume that ethnicity has such a strong effect on our genetic intelligence.

GG @Deleted User, you just advanced to level 7!

Without proper evidence we're making stuff up.

except you dont realize

that the higher your IQ is

the more likely you are gonna develop mental illness

Einstein had huge short-term memory loss and needed a secretary to write down everything he wrote

Well if it's 70% genetic then the current difference in IQ couldn't be explained with environment

It would be largely genetic too

There's a threshold where too much IQ can be bad for you

probably because brain cant handle the 200 IQ

or w/e

Totally. However, how much of that 70% is directly from you being black or white? What effect does your ethnicity have on your genetic intelligence. Zero research on this.
People will take the fact that genetics account for about 70% of IQ and then run off with it throwing out statements with zero context.

Skin color doesn't affect IQ at all.

Your brain doesn't develop extra melanin

Race is a bullshit category

No but some skin color are correlated with a smarter brain

that would be the claim

If you want to look at IQ and genes, look at ancestry.

@lemonsaw and certain political groups of people have higher IQ's

ironically

the only problem with extra melanin in your body

Libertarians have the highest IQ's

is a lack of vitamin D

>Libertarians have the highest IQ

What's the relevance?

and therefore the most mentally ill

It's a correlation

not a causation
