Narratively having Ever Given getting stuck in 2021 to set up Hormuz in 2026 is great foreshadowing. You want your audience to understand the basics of international shipping in a lower stakes context so you drop the real plot without a lot of saggy exposition about the minutiae of cargo logistics.

If we could just raise sea levels by 150 meters we get a backup Strait of Hormuz

If you group these two books with Gangsters of Capitalism by Jonathan Katz, you'd have a nice trilogy.

I read The Jakarta Papers by Vincent Bevins just after How to Hide an Empire. It felt like a sequel. The full title is The Jakarta Method: Washington's Anticommunist Crusade and the Mass Murder Program that Shaped Our World.

This looks fascinating. The pattern for Lincoln is a little different. Any thoughts on what happened there?

New study. We had adults place historical figures on the left-right ideological spectrum. Folks most often place history's villains (Hitler, Stalin, etc) as extreme examples of their opponents. But they place heroes (Jesus, MLK, Lincoln) are on their own team. 1/4 www.tandfonline.com/doi/full/10....

Most of the recent work on moral foundations theory, done by Jesse Graham and Ravi Iyer, shows that the theory holds up pretty well. The competing theory by Gray (which I assume you support) is also valid, but doesn't do away with dimensions.

Sure sounds like somebody at DOGE took the Social Security numbers and personal information of every American on record, and put it on a thumb drive to bring home to Elon Musk’s AI company.

Much as Soviet propaganda accurately depicted the United States as a racially tiered society, Iranian propaganda has accurately depicted the Trump administration as entirely run by pedophiles.

Is it sexist to say that men are more likely to be colorblind, die of COVID, be tall, die young, and so on? No because the data are clear. Someday the empirical data may support the male variability hypothesis. Or they may not.

Full Transcript: President Summers' Remarks at the National Bureau of Economic Research, Jan. 14 2005 | News | The Harvard Crimson The following is a transcript of University President Lawrence H. Summers’ remarks delivered at a conference at the National Bureau

In his public talk, I think the point he was trying to make is that the difference in variance could explain the difference in gender representation. We now know he may have had an ulterior motive but note that he had three hypotheses:

Keep calm and be transparent: advice from scientists who retracted their papers Retractions correct the scientific record, but they have stigma attached to them. Some in the research community want that to change.

We're thrilled to announce the Ctrl-Z Award, a US$2,500 prize for researchers “who discover substantial errors in their published work and take meaningful steps to correct the scientific record."

This is now called the male variability hypothesis. You can find the corresponding articles on Google Scholar. Some evidence supports it. Some doesn’t

He said there are three possible reasons for the difference in representation. One of them is that the male variance in intelligence. This means more men in the top and bottom tails.

Early Iran strikes cost $5.6 billion in munitions, Pentagon estimates The figure, accounting for the war’s first two days, is likely to intensify concerns in Congress that U.S. forces are churning through a scarce supply of advanced weaponry.

The Pentagon calculated it was spending $1 billion a day on Trump and Netanyahu’s war. The truth? It was $3 billion…and that’s just for munitions.

Plus they’ve alarmed everyone by burning through scarce munitions in a matter of days.
