So I was thinking about MIT’s “missing semester” course (missing.csail.mit.edu) on skills needed but often not explicitly taught. What are some stats/survey stats equivalents y’all find super important- that is, important for research/practice, not commonly classroom taught?

This is an absolute scandal. Trump and Marco Rubio abandoned American workers and their families abroad, delaying waivers to provide for their safe return to the United States. As these civil servants lost their possessions, housing, and money, Elon Musk was slandering them with bogus accusations.

Reminder that ipums.org has all the acs, census, CPS, NHIS, MEPS, and so much more. Bonus that it’s cleaned and harmonized in ways that make these data really easy to use in practice.

AMFAR has published a report on how the foreign aid freeze affects PEPFAR, which actually still hasn't resumed. They estimate that hundreds of thousands of people lose access to HIV antivirals and 1500 babies are expected to contract HIV — *each day* 🧵

Thanks very much to everybody who chimed in on this thread about attention --I wrote up some notes! My conclusion from the discussion is that polisci should coordinate on an info board / faux feed design to study (probs v. heterogeneous effects on attention) alexandercoppock.com/attention.pdf

I’ve been thinking about this tension lately- Trump gets credit for grabbing attention well, but a key story of last cycle is his strength with low-engagement folks. One way to resolve this is that making news might sort of sieve-like; you need to be constantly high viz everywhere to get through.

Gottheimer keeps using the "hardworking families" line but apparently does not apply that term to hardworking families who rely on the bus or the train. The only people who matter to him are the small number of people who drive into Manhattan.

Unfortunate news for those of hoping to create a healthy “niche election maps guy” ecosystem over here

Bunch of great papers here. Also, not my circus and not my monkeys, what does it say about academic publishing that something as obviously meritorious and practically useful as PSIS took that long to get published? 9 years!?

💯 from @jhendler.bsky.social — “Technology is one area where Democrats need to right the ship and think outside the box for a new era of campaigns. Although there has been progress since 2016, there are serious concerns about the fragility and sustainability of some of the DNC’s top vendors”

Did I stay up to midnight for New Years? No. Did I stay up to midnight to celebrate congestion pricing? Hell yes I did! Congratulations to all the folks who worked so hard to make this happen in the face of such bad faith opposition, it will make a huge difference for NYC.

Everyone needs to reconsider their “best/most important papers of 2024” if they missed this: arxiv.org/abs/2501.00536
