This whole chapter on antisemitism in Berlin (and Germany) is very interesting. Here you see "handed-down antisemitism" (ie not post-colonial or other newer forms) over time. #Berlin really stands out.

Apart from the question of how college admissions should work. As a factual matter, the current relationship between wealth and admissions at elite universities is almost tailor-made to generate tons of hostility and criticism among the most vocal part of society. www.nytimes.com/interactive/...

I wrote this because most journalists facing this pressure can’t. The paper we count on to check authoritarianism spiked an investigation into the Democratic Party because the party’s lawyers threatened to sue. Holding authoritarians accountable starts with holding your own side accountable.

I have read this Response to my Comment and have written a Rejoinder, showing three things: 1. The multiverse is many correlated tests. 2. The randomization inference is wrong. 3. The trichotomous moderator reaffirms my point. I also enumerate 7 misleading claims, now in print in the APSR.
A Rejoinder to ‘Still Instrumentally Inclusive’ (Turnbull-Dugarte & López Ortega)

Abstract Turnbull-Dugarte and López Ortega’s “Still Instrumentally Inclusive” (the Response) answers my replication (the Comment) of their 2024 American Political Science Review paper (the Article) with, among other things, a multiverse of 2,970 analyses based on eighteen different weighting schemes, randomization inference, and a trichotomous moderator. As I show in this rejoinder, each is undermined by bona fide errors in their code, their writing, and their interpretation. First, the multiverse is just many correlated variants of the same test. This is in large part due to the weighting schemes which suffer multiple problems (some due to code errors, some intrinsic), and are largely correlated variations on one weighting scheme. Second, due to code errors the randomization inference compares a weighted statistic against an unweighted null and, in the two heterogeneity tests, permutes the interaction column rather than treatment assignment column. Every permutation p-value the Response reports is therefore computed against the wrong reference distribution; when they are recomputed correctly, two of the five it reports as significant are no longer so, and they are the two the Response emphasizes. Third, the trichotomous moderator is erroneously described as terciles, but it is in fact based on non-tercile cutpoints. The key subgroup effect reported in the Response thus rests on comparing just thirty high-weight control respondents against thirty-one high-weight treated respondents, and ends up reaffirming my original point that the heterogeneity in study 2 is with respect to weights, and not immigration sentiment as their theory predicts. I close by documenting seven claims in the Response that are untrue or misleading.

Japan is one of the most R&D intensive non-US countries, and RIKEN is its most prestigious (non-university) research institute. If you isekai’d it into the US, it only has the fourth biggest R&D budget in the state of North Carolina, which is like the twelfth biggest state bsky.app/profile/awma...

Last month I did a little experiment. I wanted to see how the exact same post would perform on both X (Twitter) and Bluesky. The results were...interesting... [Thread]

Wer wohl dieser „Mertz“ ist, gegen den derzeit Bots laufend mit richtig schlechtem Text schießen? Das wird doch kein Transkriptionsfehler des kyrillischen Ц in „Фридрих Мерц“ sein?
