My piece today in Briefing Book: "The Economic Case for Higher Birth Rates Is Bigger than You Think"

I really enjoyed this. Separate from how you feel about population, I repeatedly had assumptions overturned by their really deep stats. Maybe my favorite pop sci read during the last year.
This is one of those "most of your intuitions are wrong" books.

New ep: The Trump-Musk doctrine of "fuck around and find out" has already demolished global aid programs, collapsed essential govt data collection services, and nearly caused a nuclear security crisis via accidental firings. This is no way to run a government.

Govt efficiency would be a worthy goal, even if interest payments didn't exceed defense spending. But understanding efficiency means understanding tradeoffs. So I talk to health policy profs Michael Geruso and Tim Layton about the art of finding real waste in govt.
