A year long investigation into the Hyperloop found …
“The truth was far simpler, far dumber, and far more prescient: Musk and his lieutenants truly had no idea what they were doing.”

this is very grim
During a Sept White House briefing, President Trump raised concerns about #Tylenol use during pregnancy. A sharp change nationwide in how doctors prescribed that medication followed. “The results show just how much political leaders can steer health behavior," Professor @mlbarnett.bsky.social says.
I think it's the latter most likely. Can't really observe it without very different data!
From @jeremyfaust.bsky.social
“Doctors and scientists quickly said the data didn't support the president's claim, but emergency room orders for Tylenol, or acetaminophen, for pregnant patients went down 10% in the months that followed”
you can use some tricks to get powerful output actually. we have at least two other pretty big papers in the works using SlicerDicer if you can believe it
we used SlicerDicer for these data so these dates are real actually! I think the dates are scrambled for the more detailed encounter-level data available in their "data science" environment
1) better than expected!
2) yes :)
What happened after the weird Sept 2025 White House press conference on autism?
📉 Tylenol use in the ED dropped >10% among pregnant patients
📈 leucovorin rx jumped 93% among kids 5-17 immediately afterwards

Thanks to my intrepid and brilliant co-author @jeremyfaust.bsky.social and @thelancet.com for publishing. Please share thoughts and feedback!

Federal health officials have enormous sway in shifting health behaviors. as @jeremyfaust.bsky.social put in @washingtonpost.com "There are people who listen to our leaders, and they have an enormous responsibility to speak in a way that the science reflects"

Figure Weekly emergency department orders and outpatient prescriptions, June 30 to Dec 7, 2025 (A) Pregnant female individuals aged 15–44 years. Emergency department orders for non-pregnant females (aged 15–44 years) are displayed in the appendix (p 5). (B) Children aged 5–17 years. Note that scales differ between the left axis (folic acid, risperidone, and aripiprazole) and right axis (leucovorin). Modelled expected rates are shown as dashed lines of the same colour. For both panels, the grey vertical dashed line indicates Sept 22, 2025, the date of the White House briefing. Observed-to-expected numbers and ratios with 95% CIs for each medication for the study period (Sept 22 to Dec 7) and the initial month of the study period (Sept 22 to Oct 19) are shown in the appendix (pp 3, 4, 6).
Second, the press conference promoted the use of leucovorin for treatment of autism, even though its potential use only applies to a very rare subset of kids.
Here, we looked at leucovorin prescriptions among kids 5-17 compared to other FDA-approved meds for autism and also saw a huge spike.

First, President Trump cautioned against acetaminophen use in pregnancy using a cherry picked study. We looked at how this might change behavior of pregnant patients in the ED.
We found an immediate drop of ~16% in use of Tylenol among pregnant women without changes in control meds.

Using the powerful Epic Cosmos electronic health record database @jeremyfaust.bsky.social and I looked at changes coming from two key recommendations during the widely covered Sept. 22 2025 White House press conference on autism. We found a surprisingly abrupt and immediate public response.

Chart showing in many countries, people see their fellow citizens as morally good.
We asked people around the world to rate the morality and ethics of others in their country.
The U.S. is the only place we surveyed where more adults describe the morality and ethics of others living in the country as bad than good. See our full morality report here: www.pewresearch.org/...
A Canadian journal has issued corrections on 138 case reports it published over the last 25 years to add a disclaimer:
The cases described are fictional.

NEW: I and colleagues reviewed 15,000 documents to illuminate how Jeffrey Epstein used VIP doctors to control and manipulate young women* — and how the doctors helped him, treating his needs as more important than the patients'. Gift link.

The Nazis stopped Jewish doctors from practising, so thousands of them left the country (my great grandfather was one of them). So many left that this was a good natural experiment for estimating the causal effect of losing doctors on infant mortality (& thousands died)

Interesting paper on effect of smart phone usage of traffic fatalities. They exploit major album release dates and a RDD design and find that traffic fatalities increase by 10 persons on the day of release of major albums. So, rock music IS dangerous! www.nber.org/papers/w34866
wow

Sure, WSJ. Shame on me for worrying about patient access to care and taxpayer spending over for profit companies. As long as the system works for the wealthy it must be fine with you. Enjoying the comments on the piece, though.
