Fascinating conversation, indeed! Plomin is one of my quiet heroes. Perseverance in pursuit of truth. Follow the evidence where it leads. It takes courage. It shouldn't have to but it does.
The implication of 'p' factor as analogous to 'g' factor is potentially revolutionary. Throw out the DSM.
that's it I'm going to make a conspiracy theory about how the vaccines are going to kill all the compliant people as a method of selecting for individualist, liberal, revolutionary traits to create a population who will reject Christ
I believe this is false also because heritability of IQ is only 50% if we average over the studies that measure this, which are taken at different ages of the participants.
IQ indeed like all cognitive factors increases in heritability as people age and by 30 I believe the number is closer to 80% not 50%. This coupled with the fact that inheritance is not Markov (so grandparents' IQ matters even fixing parents IQ) signifies to me that two 130 IQ parents should have a child in EV closer to 125 IQ.
The easiest way to see regression to the mean is by looking at a person's height. Tall parents have tall children. But on average, the kids will not be taller than their parents.
This is all about averages when you have no control over selection. But with embryo selection, smarter parents will be able to select smarter kids.

"And as Jesus passed by, he saw a man which was blind from his birth.
And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind?
Jesus answered, Neither hath this man sinned, nor his parents" (John 9:1-3)

Richard, is there a way to download the CSPI podcasts without using one of the podcast apps? Just a right-click save-as method?

I think Robert is wrong about this, but I will check it out.
