"Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%,[6] with some recent studies showing heritability for IQ as high as 80%.[7] IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults. The heritability of IQ increases with the child's age and reaches a plateau at 18–20 years old, continuing at that level well into adulthood." [0]

You're denying settled science. Trying to tie it to the Bell Curve to assassinate the basic character of the science isn't tricking anyone. Pronouns in your profile only make this bad faith move easier to identify.

Really? Using the fact that someone put pronouns in their profile is a bad faith move? Your account is literally a throwaway.

Calling these twin studies as settled science is the most bad faith move here, since the chief problem of this section of The Bell Curve is that it confuses heritability with genetic determination, a mistake that informed scientists wouldn’t make. Unsurprisingly, that is why there is widespread scientific backlash against it.

Believe it or not, twin black babies separated at birth and raised with white parents are still treated as black by society.

>Really?

Yes really.

>Using the fact that someone put pronouns in their profile is a bad faith move?

No, putting pronouns in your profile is a red flag for bad faith moves.

>Your account is literally a throwaway.

Which means you can expect unadulterated facts.

>Calling these twin studies as settled science is the most bad faith move here

No it's not, stop denying the science.

>since the chief problem of this section of The Bell Curve is that it confuses heritability with genetic determination

The Bell Curve makes no confusion between heritability and genetic determination.

>mistake that informed scientists wouldn’t make

Good thing the Bell Curve didn't make that mistake!

>Unsurprisingly, that is why there is widespread scientific backlash against it.

There wasn't much scientific backlash to it because it's fairly bulletproof. The backlash was because of contained heretical topics, and may have pointed to blasphemous conclusions.

>Believe it or not, twin black babies separated at birth and raised with white parents are still treated as black by society.

"Believe it or not, twin Asian babies separated at birth and raised with white parents are still treated as Asian by society."

You're almost there /r/selfawarewolves.

Twin studies can't prove something is caused by "genetics"[0]; twins are not free of environmental factors and don't necessarily have the same genome. Genetics, like many scientific fields that can't do real experiments, is just people abusing statistics for fun.

[0] if it did, this wouldn't mean anything, because it can't be used to make predictions, because you don't know if any random person X you are trying to predict trait Y of has these "genetics".

I don't really have a horse in this race but you're basically denying the ability of science to have anything to say outside of the hard sciences, which I disagree strongly with.

"Can't be used to make predictions"... seriously? These factors can be used to make predictions. Now whether these things are just correlates with other more fundamental factors, or causal - I thought that was where the conflict was.

No, economics can make useful predictions because they understand proper study design. Most other fields can't though.

How heritable is height?

https://edition.cnn.com/2016/07/26/health/human-height-chang...

For bonus points: why has the heritability of height changed over time and varied by country?

[throwawayacc5]

>How heritable is height?

Very, somewhere in the 80% range: "The estimated heritability was 0.79 (SE 0.09) for height and 0.40 (SE 0.09) for BMI, consistent with pedigree estimates." [0][1]

>For bonus points: why has the heritability of height changed over time

It hasn't.

>and varied by country?

It hasn't.

Love it when the bonus questions are easier than the main questions.
