Have had the same reaction in the last year. Case in point: juries have performed so much better than other institutions!

I mostly agree with the larger point, I think: political effects of economic conditions are mediated through the media (writ large), which may not always reflect actual conditions.

But tbc you can estimate the causal effect of X on Y and see if it is big or ~0! Don't let NHST tell you otherwise!

New WP! Philip O'Sullivan, Kosuke Imai, and I generalize an earlier SMC sampler for redistricting plans, allowing it to scale better & be applied to multi-member districts, too, like the Dáil Éireann (Irish parliament) below.

Look for a new 'redist' version soon(ish)!

LA City Council’s City President Marqueece Harris-Dawson says he has been pulled over four times while a member of the council; the most recent was this week. He missed a committee meeting because of the stop, according to him.

Among the questions: “how do you have this vehicle,” according to him.

I just cannot underscore enough how uselessly simplistic this WAR-based mode of thinking about elections is. And it’s not even accurate! In Jain’s own construction WAR explains 25% of future residual candidate performance, including fundraising, candidate skill, district fit, & general vibes-y stuff

v0.2 of `bases` is up on CRAN! `bases` brings nonparametrics into your favorite modeling functions—using random Fourier features is as easy as sticking `b_rff()` into your formula.

v0.2 brings graph Fourier & random convolutional features, `mgcv` integration, & more!

I'd very much like to return to a world where academia, the sciences, the media, etc. *can* be neutral because everyone accepts their right to flourish, but that's not the reality we're living in.

The entire Democratic strategy debate — "moderate" or move left? fight or compromise? — is based on a misreading of data. Voters don't think Dems are too progressive; they think Dems are weak. The actual math on what to do about this isn't even close!

Redistricting Reforms Reduce Gerrymandering by Constraining Partisan Actors is now forthcoming in the APSR!

We use a game theoretic treatment and continuous DiD(iD) to show when redistricting reforms work

Specifically, the “issue” is/was my (non-)compliance with Regulation 9.016. A similar presentation I gave in Finland in October was also flagged for violating this same regulation because I had “transgender” in the title there too. www.flbog.edu/wp-content/u...

finally: to the extent that it's possible safety isn't found in secrecy, it's found in numbers, and the former is at odds with achieving the latter.

🇺🇸 trifectas get <one> shot at doing something

Obama chose policy (ACA). It didn’t fix the authoritarian problem

Biden chose policy (ARP/IRA). It didn’t fix the authoritarian problem

The platform must be <immediate> institutional reform next time. Right from the start, as @dhnexon.bsky.social said

Anyway, I am skeptical of many suggestions of the reform movement (eg preregistration, registered reports, etc) because they do not address the underlying incentives, nor do they alter the purpose of the system.

One thing I hope people take the time to acknowledge: The sea change in public opinion has been achieved because violence, though encourage by a lot of people here online, was never once employed by the movement. Violence was solely the purview of the state and that is why the state is losing.

The administration is boxed into a corner right now and its entirely the result of the incredible discipline of the people in the streets. The Insurrection Act angle was always predicated on ICE brawling with the black bloc in street. Without that, it's worthless.
