Parental intelligence is strongly causally coupled with their children's future intelligence simply through their working vocabulary and talkativeness
Your statement is correct, but your assumed cause is not. It's 60-80% genes: https://jaymans.files.wordpress.com/2014/04/iq-heritability-age.png https://jaymans.files.wordpress.com/2014/04/iq-heritability-...
- saulrh 11y agoI guess I should have worded it to better indicate that what I gave is a simple, obvious, and uncontroversial example of things that go into causal coupling between parental and child intelligence, but not the only or even remotely the strongest element. There are many reasons why being born to unintelligent or poor parents is incredibly unfair. It is present, but relatively weakly compared to genetics: http://literacy.rice.edu/thirty-million-word-gap http://literacy.rice.edu/thirty-million-word-gap
