Summers called this female Chinese economist “peril.”

“Yellow peril” was partially built on the claim that Chinese women were sexually immoral threats.

That logic fueled the Page Act of 1875, which barred Chinese women by presuming they were prostitutes, even before the 1882 Chinese Exclusion Act.
Summers conferred with Epstein frequently about how to extract sexual favors from a Harvard econ grad (AB '04, PhD '09)

The grad is from China

Epstein and Summers referred to her by the codename "Peril"

Racism and sexual exploitation in one efficient package

That's the fascinating part of this to me. Just about EVERYONE has experience with ibuprofen. You can experience the pain getting better. You could conduct your own personalized trials to prove to yourself that it worked, if you really doubted it.
I have had two separate lower wisdom tooth removals. For one I got paracetamol, the other one ibuprofen. There was much less pain when I used ibuprofen. N=1, but it adds to the review.

We don't just have evidence that ibuprofen works, we have things like a cochrane review finding two high-quality RCTs showing ibuprofen works better than acetaminophen for dental pain after lower wisdom tooth removal. www.cochranelibrary.com/cdsr/doi/10....

I didn't understand an econ paper unless I'd gone to the trouble of taking it to pieces and putting it back together, better still programmed the thing in a computer and solved it myself.

One of the things I discovered about my own learning was that unless I went to the trouble of trying to reconstruct whatever model, argument, proof, reasoning myself, step by step, from scratch, I did not really see or understand its whole in my mind.

Any pro-democracy, pro-market lessons for the world as formerly robust democracies slip rapidly towards autocracy?
I read this whole thing & learned what anyone who understands how absolute, arbitrary power works would expect:

The prince asked for the impossible, was told by toadies it was in fact possible if expensive, then wasted billions as no one could tell him it wouldn't work (while many cashed checks)

Total federal spending is up +7% in 2025 over 2024 year-to-date to Oct 20.

The story that the fed govt is tightening its belt is contradicted by its own real-time expenditure data. Admin spectacularly hammering some things but raising spending elsewhere.

Was -7% just after Inauguration Day.
