The problem with #rstats is portability. Shit like `df$x` has to be converted to `df€x` in Europe and `df£x` in the UK but nobody talks about this.

a thought i’ll put out there: it is not the ideological moderation that is the electoral problem, it is that selecting for candidates who chase popular issue positions is necessarily selecting for candidates who exude the kind of focused-group affect that voters genuinely hate

"When a survey question defines tariffs as taxes on imports, for example, fewer people say they support them. When a survey question calls out specific countries, more are in favor of tariffs on China than on other countries."

Here's a cool, simple technique I learned from Joey Cherdarchuk ( @obumbratta.com ): in a choropleth map, your legend can double as a histogram - showing both the colour coding ánd the data distribution.

recent scholarship agrees that the invention of shredded cheese was a collaborative effort, a history that runs contrary to the claims by some proponents of the so called "grate man theory"

The theory is that price gouging is a good thing because the people who get the most utility from a good are the most Willing To Pay.

Just a coincidence I guess that people with more money are more Willing To Pay

People don't really think any of this! Overestimates of small proportions are a quirk of general innumeracy, not genuine misperceptions.

Outraged by Jan 6, he spent two years getting inside the top ranks of militias like the Oath Keepers. He was stunningly successful. He penetrated a new generation of militia leaders, which included doctors, cops & government attorneys.

In economics, editors, referees, and authors often behave as if a published paper should reflect some kind of authoritative consensus.

As a result, valuable debate happens in secret, and the resulting paper is an opaque compromise with anonymous co-authors called referees.

Being a pedant here but the French revolution was not sparked by increasing wealth inequality, but the exact opposite: an increasingly wealthy and educated bourgeoisie resentful of the inherited privileges of an aristocratic class. The leaders of the third estate in the estates general were rich.

That a dude with a couple cameras and a plate of appetizers can make something worth $82.5 million and a media company looks at that and goes "couldn't we make even more money if we had AI do it?" tells you exactly how stupid these people are
The $82.5 million sale of "Hot Ones" studio First We Feast is part of a broader strategy at BuzzFeed to shift away from human editors, writers and content producers in favor of artificial intelligence, which result in "high-margin, tech-enabled revenue lines."

Maybe an unpopular opinion, but I hate the term "skeet" to refer to bluesky posts. Please tell me that it's just a tongue-in-cheek colloquialism that can die out rather than the official term that the company uses.

New paper: Do social media algorithms shape affective polarization?

We ran a field experiment on X/Twitter (N=1,256) using LLMs to rerank content in real-time, adjusting exposure to polarizing posts. Result: Algorithmic ranking impacts feelings toward the political outgroup! 🧵⬇️

I straight up think it is dishonest to make this claim without noting that a) the mobilization against the Muslim ban involved a thousands of actual people flooding airports and b) coincided with a massive mobilization of people on the ground in Washington D.C.

an overlooked aspect of all these “bluesky is an echo chamber” pieces is that the writers bizarrely think that the only reason people use social media is to talk about politics, which is true only for a subset of users
