Elon's little serfs are quite literally begging journalists to come back because every publicly available source of data shows people have fled the platform and young people won't use it.

They are literally begging regular people to come back. Don't do it! It is a website by and for actual Nazis!

To thwart malicious prompts, large language models use filters that are smaller than the models themselves. Recently, the Turing Award-winning cryptographer Shafi Goldwasser and researcher Sarah Ball showed that this size disparity makes LLMs insecure. www.quantamagazine.org/cryptographe...

1. This is how the story "Sanctuary" from Detective Comics #551-552 started.

Back then was INS. The kid showed his passport after this, but his brother is not in the same situation.

NEW: Brown econ prof Rachel Friedberg says the shooting happened in a finals review session:

"The room has stadium seating with doors that enter at the top. [The TA] said that the shooter came in the doors, yelled something ... and started shooting." www.oceanstatemedia.org/news-and-cul...
Rachel Friedberg, a Brown economics professor, said the mass shooting happened in a review session for the final exam of her Principles of Economics course. She said she learned what happened from a teaching assistant who led the session. Friedberg herself was not present. "The room has stadium seating with doors that enter at the top," Friedberg said. "He said that the shooter came in the doors, yelled something — he couldn't remember what he yelled — and started shooting." "Students started to scramble to try to get away from the shooter, trying to get lower down in the stadium seating, and people got shot," Friedberg said. "I don't know if they're the only ones who got shot or not."

In American high schools, many teenagers are assigned few full books to read from beginning to end — often just one or two per year, according to researchers and thousands of responses to an informal reader survey by The New York Times. trib.al/gNp7kWK

With this setup, basically all the results disappear. I think rdrobust is not great in these types of discrete designs, unfortunately.

Overall, I think rdrobust is the wrong tool for this given the discreteness in the running variable (see Kolesar and Rothe (2018)).

To do this, you need to pick a bound on the second derivative. I am VERY generous, and pick a bound of M=0.01.

I was also bored and pulled up the replication package.

The results are quite sensitive in aggregate to needing the controls. Here's the replication of Figure 3, including the case w/o controls:

I ignored the strip.clip argument in #ggplot2 for way too long 😲

Combined with a small negative margin tweak, you can place facet labels inside each panel. A tiny trick that makes small multiples feel so much cleaner.

🔵 no manual coordinates
🔵 inherits theme styling
🔵 scales nicely when resizing
Side-by-side comparison of two multi-panel bubble charts faceted by world region. The left column shows the default facet labels placed above each panel (“Africa”, “Americas”, “Asia”, “Europe”, “Oceania”). The right column shows the same charts, but the facet labels are moved inside each panel at the top-left using a negative margin. In the center, there is a title reading “Want to place your facet labels inside each panel?” with an arrow pointing right, followed by a short ggplot2 theme code snippet demonstrating how to move strip text inside the panel.

Um, ok...

This paper forthcoming at the JOP provides evidence that rent control in Germany actually made tenants MASSIVELY *less* NIMBY.

This result was in the opposite direction of the authors' pre-registered expectations.

And the effect sizes are, truly, massive.

Yes, that's what I would've thought, but either a) they aren't finishing the Phds (e.g. they're taking the masters and doing this) or b) the departments are only reporting PhD grantees don't go into industry. But that isn't in line with the usual survey reporting.
