Anyone planning on filing for the Anthropic lawsuit? I saw one of my books in the database list and not sure what to do.

Stop submitting AI slop to journals and preprint servers

This is anti-social behavior. It is making life harder for everyone involved except for the person submitting the slop

In light of record submission rates and a large volume of AI-generated slop, SocArXiv recently implemented a policy requiring ORCIDs linked in the OSF profile of submitting authors, and narrowing our focus to social science subjects. Today we are taking two more steps:

The Myth of a Rightward Realignment

Let’s discard some stubborn misconceptions about Trump’s support and what happened in the 2024 election. They are only obscuring our understanding of a profound de-alignment.

As the piece is partially behind a paywall, I’ll share some key thoughts:

So, is "When Prophesy Fails"—the foundation of cognitive dissonance theory—debunked?

Unclear. The article making this claim is... odd.

It describes Festinger and Schachter as leftwing radicals, critiques the political slant of their funding, generally refers to their work as failed...

Honestly this was a very hard paper to write in midst of everything that’s been happening here… deportation is truly an inhumane policy…

Meritocracy is a form of system justifying ideology. Extending recent work on SJT by @efrenpolipsy.bsky.social, we found that stronger endorsement or meritocracy predicted more support for deportation and less worry about deportation for both Latinos and Asian Americans

The first of the two is a collab with political scientist Nathan Chan. We used two waves of CMPS data (including the latest 2024) to examine relationship between meritocracy and deportation sentiments among Asian and Latino Americans

Very interesting polling results on redistricting. Voters support independent redistricting; and/but want maps that help their parties right now. www.politico.com/news/2025/11/21/poll-redistricting-partisan-gerrymandering-midterms-00663612

Poll: Voters support gerrymandering to win the midterms

A majority of both Democrats and Republicans support redrawing congressional districts to give their side a boost next year.

My preferred view is that public is center-left on policy & representation but center-right on symbols & orientations. Other common alternatives are (1) public is centrist if measured properly, (2) public is center left but bigotry moves right, & (3) Dems strategy is bad/unlucky

I wouldn’t go with clustering SEs because you’re then treating the clusters as spatially independent of each other. I’d instead use LM diagnostics to see if you have lag or error dependence, or both.

Using open-ended responses to a question about your ideal political party to place voters on an ideological spectrum & how much they think ideologically

G Elliott Morris @gelliottmorris.com · 7d

Good morning. I've got a banger new post out today that develops a new method for placing voters on the left-right ideological spectrum, and adds a new, "non-ideological"/affordability axis to usual way we chart & think about US voters (esp swing voters). www.gelliottmorris.com/p/not-just-l...

Not just left vs right: Most voters think about affordability and material wellbeing, not in ideological terms

Most voters want a party that emphasizes cost of living issues and makes the world a better place. Few Americans think in solidly ideologically terms. "Moderates" are mostly non-ideological.

Always amazed how, each semester, teaching data analysis inevitably teaches me something new.

This week I learned that spatially correlated residuals in FE models (w/ data from Bailey's great book) probably doesn't require clustering SEs. Thx to @nickchk.com's AMAZING website--what a resource! 🙏

Borders Czar Tom Homan just announced he’s ramping up ICE operations in NYC.

Same playbook we’ve been seeing in LA, DC, Chicago & Charlotte. They aren’t hunting criminals, they’re targeting workers and people who are part of the community. Families. Neighbors. The people who keep the city running.

I've missed writing, so I wrote a piece on how the parties are judging their oldest leaders. And decided to hop on the substack trend where I'll write about American politics, public opinion, and (sometimes) tennis!

substack.com/home/post/p-...

Democrats Want Younger Leaders. Republicans Don’t.

Data shows that the parties diverge in how they judge their oldest leaders.
