It is depressing, but all too predictable, how swiftly we’ve gone from the Social Science Genetic Association Consortium offering reassurances about the uses of behavioural polygenic scores to one of their lead authors marketing embryo selection for IQ

I don’t think anyone is prepared for what they just did w/ ICE.
This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined.
It is setting up to make what’s happening now look like child’s play. And people are disappearing.

Why has fertility suddenly crashed everywhere all at once?
Certainly, there are many factors, which vary across all world regions & over time.
I’ve written on many of these!
But we should also recognise the collapse of coupling.
Always open to new data & ideas! 🙂
