Not really the point, but it's a bit weird to say that Bayes can be 'gamed' by choosing priors to support your conclusion. I mean, how is that gaming? Where's the subterfuge? Do we not make fun of villains who elaborate their plans to the viewer?

don't be mystified. it's just log probabilities. log probability -> "information" / "surprisal".
S-Values are much more interpretable than P-values, yet adoption seems near impossible. I wonder what it would take to make the leap? #statssky #episky #rstats #statistics

The 1993 mid-handoff moment between shoegaze and Britpop has always been one of my hyperspecific musical sweet spots. Zach does a tremendous job here capturing both that moment and probably the greatest album it produced.
For this week's Sunday Review, I went long on one of my favorite albums of all time: Giant Steps by the Boo Radleys.

Read Zach Schoenfeld’s review of the album.

Jeffrey Goldberg's editorial leadership has been a disaster for the human race
Over many interviews, Robert F. Kennedy Jr. told Michael Scherer about how he plans to remake America’s public-health system. Can he lead the scientific establishment he’s spent much of his life crusading against?

What a goddamn legend. Every big tough conservative masculinity guy has been crying about how terrifying cities are to live in for the past two years and now Trump wants to move back to NYC
Reporter to Trump: Would you feel comfortable living in NYC under a Mamdani mayoralty?
Trump: "I would. I really would. Especially after the meeting, absolutely."

A reporter asks if Mamdani stands by calling Trump a fascist. Mamdani starts to give a delicate answer.
Trump (smiles, pats Mamdani's arm): "That's OK, you can just say yes. It's easier. I don't mind."

The semiliterate people who use chatgpt like to point to calculators as a precedent of assistive technology but the thing is: calculators actually calculate.
A calculator really does let you outsource calculation. It does exactly what it is supposed to do, and marketed as doing, reproducibly.

New from me: I talked to CDC staffers about the new vaccines and autism page. They said things like:
“The best way I can put it is it feels like we’re on a hijacked airplane.”
“I think people are starting to see that we can’t fulfill our mission here.”

The occupation of HHS by Robert F. Kennedy Jr. has crossed a line that should be UNACCEPTABLE by any American.
Congress needs to DO THEIR JOB and rid of us of this threat to our health, lives and national security. This is not hyperbole.
This is INTOLERABLE.
