I’ve posted much less in 2025 bc I’m a childhood sexual assault survivor who must follow politics for my job. I’m usually capable of standing up when politics get personal, but I’m struggling. I hate it and feel weak. If you are incensed by Epstein/Trump and can do more than post about it, pls do!

It’s almost as if drastically limiting major trading relationships has economic consequences
I wonder if the United States can learn anything from the last time a major industrialized country decided to isolate itself from the rest of the world?

Almost a decade after the Brexit vote, GDP in the UK is around 6-8% lower relative to peer countries. (Source: www.nber.org/papers/w34459)

Somehow he goes so far beyond saying the quiet part out loud that he circles back around to somewhere in the vicinity of the truth
love that he is (correctly!) telling his followers to blame republicans for everything bad that happens in the next three years
you, wise: "lol you think there's gonna be more elections? trump's gonna cancel them"

me, dumb: "well, someone should tell donald trump then"

FYI, ‘announce causation based on a few bad studies claiming correlation then pay people to make the proof’ is not how the scientific method works. It’s not just bad deductively, it’s not even good inductive reasoning.
RFK Jr on Tylenol and autism: "It is not proof. We're doing the studies to make the proof."

This! The bbc’s story is absolutely not good science communication!
Timely reminder that 'associative' language leads lay people to confuse correlation and causation, as @tomerullman.bsky.social and I showed a few years ago.

A good reason for faculty to join the @aaup.org , which fights for academic freedom and works to defend against attacks like this.
100%. I'm sure the inboxes of every dep't chair, dean, and university president are currently full of complaints from students who dislike aspects of their classes. Those coming from right-wing students are coupled with threats that the next stop is DOJ.
A reminder that the DOJ wants to investigate the issue. The DOJ wasting time investigating our classrooms is an open invitation for any frivolous complaint from any student, anywhere with too much time on their hands.

I used to hear my older and wiser NHS interviewees talk about how every reorganization recapitulated one they had already been through, and how existentially boring it was, and calibrate their retirement accordingly. I understood intellectually. More and more I also feel how they feel.

Rural Hospital Closures Led To Increased Prices At Nearby ‘Surviving’ Hospitals, 2012–22
Rural Hospital Closures Led To Increased Prices At Nearby ‘Surviving’ Hospitals, 2012–22 | Health Affairs Journal
Rural hospitals in the US have closed at a rapid pace in recent years, raising concerns about decreased access to care and declining competition in rural markets. Because prices paid by commercial health insurance plans are negotiated between hospitals and insurers, hospital closure may give “surviving” hospitals increased leverage to negotiate higher prices. Using commercial claims data, we studied the effect of hospital closure on the prices charged by nearby surviving hospitals. We found that hospital closures during the period 2014–18 led to a 3.6 percent increase in prices at surviving hospitals, driven by larger price increases in the three to four years after closure. Price effects were concentrated among surviving hospitals with market power—hospitals with system affiliations and hospitals operating in less competitive markets. We also found that closed hospitals charged lower prices than nearby hospitals in the preclosure period. Thus, closure eliminated low-price hospital options from rural markets. Overall, our findings suggest that hospital closure can have a meaningful impact on commercial prices. Policies targeting rural hospitals should consider the anticompetitive effects of closure, in addition to devoting continued attention to access to and quality of care.

Ah yes, the paper we wrote on Brexit and drug prices during Trump one seems relevant here. Note the drug policy in question was a half baked policy blueprint. By comparison, today’s EO would place dead last in the technical.

This is infuriating me from the core of my being. I guess my PhD still matters. I guess I should put ‘assess fake UK trade deal’ on my to do list, but boy I don’t want to
It was interesting that the @washingtonpost.com’s headline used “trade deal,” but when you linked to the actual story, the headline became “pact”
