I think it would be better if there were fewer grand claims about how AI is going to revolutionize research and more people trying to make the best use of AI to improve their research, and let’s see what we get.

Three days after reading the 170 pages of opinions in the tariffs case, I can’t help wondering whether (and how long) the Court delayed giving hugely important information to the world so that Justices could more extensively carp at each other, in dicta, about principles of statutory interpretation.

Straight into my veins. Ordinary statutory interpretation and constitutional requirements adequately addresses delegation. Gorsuch's MQD, invented out of wholecloth, should have no role in deciding separation of powers cases.

Arguing that the Court can't overturn a blantantly unconsitutional act because enforcing the decision would create a "mess" really fails a test of ex ante vs. ex post incentives.

Using this data we run the models Fowler and Hall run in their paper and we find.... no shark attacks effects. We think the takeaways of this are that (1) if you combine our findings with those of F&H it seems like there was no blind retrospection in 1916 in response to the shark attacks.

“Universities won’t be hurt, they have billion dollar endowments!” 1) most don’t—we are talking low single-digit percentages. 2) you can depend on 4 to 5 percent of asset value as income—$1 billion = $50 million. 3) restrictions on how that $ can be spent are real—this isn’t a checking account

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

FWIW, ICE is largely funded at the moment via the supplementals in the OBBBA, so the 2-week CR isn’t giving them much of anything they wouldn’t otherwise have.

It’s hard to accurately describe what is happening in Minneapolis without sounding crazy. Unmarked rental vans all over the city, with people in military gear and no id jumping out of them to take captive anyone who looks nonwhite or who makes political speech they disagree with.

The justices keep returning to the hypo of a Fed governor posting pro-Nazi videos to ask whether that would meet the bar for for-cause removal. The idea that this kind of content would obviously cross the line seems a bit farcical given some of the material that DHS regularly posts on social media

Both can be true: 1. Trump has not been very successful by traditional metrics of the presidency. 2. He's playing a different game and is trying to consolidate an authoritarian regime. Suggesting he's not having a big impact because he's not passing laws is a category error.

I'm not quite sure how this is true, given that he's not seeking new statutory authority for ... pretty much any of this. At most, what they could do is shut down the government + refuse to confirm any more Trump nominees.
