Could this have to so with smart people increasing pursuing hedonism over reproduction? Maybe Idiocracy was right all along.

From a strict evolutionary perspective I have doubts that a high IQ is useful anymore.

The point of the original Flynn effect being a big deal was that the changes were faster than was possible with genetics alone.

A big part of "The Bell Curve" was arguing that no interventions could change IQ except genetics and so any money spent on low IQ people (African-Americans in the book, but the author followed up by attacking poor people more generally) was a pointless waste.

It turns out he wasn't just an asshole, he was also wrong.

What is going on with Bell Curve apologists all of a sudden replying to this post. I thought the debate was slowly fading out and than I count 5 different account replying within an hour.

"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.

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?

>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.
