Was rereading Bartels's Ethnic antagonism article & found a good example of what not accounting for method can do. He estimates an acquiescence factor to control for method effects b/c outcomes and many predictors share response scales. These are hearty method effects.

A lot of people are looking at this as insider trading but it's an even bigger issue for national security if there was advance warning of air strikes.

Three more Wisconsin county sheriffs agree to work with ICE • Wisconsin Examiner Three more Wisconsin county sheriff's offices have signed agreements that allow deputies to cooperate with ICE enforcement efforts.

Gov. Evers should cancel these agreements by county sheriffs in WI. wisconsinexaminer.com/briefs/three...

I'm coding up nearly the full 2024 ANES this week, and damn, they did well.

Really great new incisive questions while maintaining continuity with old items, the spousal interview supplement, and the 2016-20-24 EIGHT year panel!

Last night @spspnews.bsky.social celebrated the accomplishments of @afhayes.bsky.social, awarding him the Methodological Innovator Award. It was incredibly moving to see methods development celebrated at #SPSP2026. Congratulations Andy!

Trump loves Mamdani because he loves celebrity and rizz. Mamdani also leverages Trump’s self-identity as “NY developer.” I think AOC would also pull this off if not for the sexism.

Writing simulations in DeclareDesign just went from "I should do that, but it's kind of a lot of work" to extremely easy

If folks are using GenAI to search for info, might be important to know what's returned and how consistently. Neat application here to political candidates. To me the variance across LLMs in what sources are included and how regularly is fascinating.

Your friends at the ANES would appreciate your proposals for new content that we will pilot immediately after the 2026 midterm elections. Please see the announcement at the following link and submit your ideas! electionstudies.org/anes-announc...

Americans' Support for Same-Sex Marriage Do you think marriages between same-sex couples should or should not be recognized by the law as valid, with the same rights as traditional marriages? % Should be valid

@amengel.bsky.social posted this earlier but I can’t find it. Wonder if some of this change since 2020 is evidence of changing composition of the GOP to Indies? news.gallup.com/poll/691139/...

Interesting AmericasBarometer result from @johnsides.bsky.social in this week's @goodauth.bsky.social newsletter. Strong public willingness to trade features of democracy (free elections, free expression) for material and physical security, with some party differences.

New polling says Jasmine Crockett has the best chances to beat Ken Paxton in Texas.

The “she can’t win” crowd might want to start updating their talking points because the voters know what’s up.

Akhil Amar on birthright citizenship:

”Unless and until our Constitution is amended, our government is simply not allowed to punish innocent babies guaranteed full and equal citizenship by the Constitution itself.”

Cutting down the manuscript word-count to fit the journal requirements🤦🏽

This is not the main thrust of the piece, but I grew up in an evangelical tradition where men were the only ones allowed to lead in any way.

If you were a baptized male, even a teen, you were in a leadership position over the women.

That meant prayers, sermons, scripture reading, and communion

Universities were once entirely populated by white Christian men of means. Every step toward social equality meant fewer white supremacist and misogynistic ideas were considered true by default, and competition for jobs grew more challenging. They want to go back.
