I'd actually love to see that study. But before you link it I'll dispute it anyways which is that this a problem with a third variable, wealth. Wealthy parents raise IQs by being more attentive, allowing children to attend better schools, etc.

Yes it is.

Assuming I understand your motivation for posting the IQ heritability article - yes, higher IQ parents will have higher IQ children, leading to compounding effects. This could (at most) lead to widening of IQ distributions where intelligence-based selection effects are amplified. However, since meritocratic positions sample from a fraction of the population, not an IQ or “merit points” range, this shouldn’t really have any strong anti-meritocratic effect.
> Yes it is.
Well I’m glad you settled that.
