Don't Take Your Guns to Town? Rural Socialization and the Long-Term Politics of Firearms | Journal of Health Politics, Policy and Law | Duke University Press

New paper @jhppl.bsky.social (w/ Michael Shepherd & Alee Lockman) where we find Americans who grew up (socialized) in rural areas are more likely to own guns, support the NRA, & hold more conservative firearm policy attitudes over the lifespan, even after moving away. 1/

A bit higher levels of disapproval of ICE enforcement than Trump's policies (53 to 32 disapproving)

Same for deporting undocumented immigrants who have been in US for many years, have jobs, & have no criminal record (47 to 30 disapproving)

& much more in the report...

Big racial/ethnic splits, with white respondents evenly split, and every non-white group 2:1 or more disapproving.

Big gender splits (women 55 to 31 disapproving)

Large generational splits (18-24 year olds 62 to 24 opposed)

Big SES splits (lower SES much less approving)

I am gonna double down on this a little: the reaction of many senior academics to fairly banal LLM takes like ‘they’re useful tools’ is extremely unbecoming, & would, if I was your graduate student or junior colleague, actively make me feel like I had to either lie to you or de facto hobble myself

This is exactly it. And I would emphasize one other thing: we, society, *will* figure out a better way to incorporate these tools into workflows. It's absolutely chaotic right now, with a ton of misuse. We're in a transition phase and we will figure it out. Right now is the most chaotic it will be.

Grammarly Is Facing a Class Action Lawsuit Over Its AI ‘Expert Review’ Feature The feature, which Grammarly shut down Wednesday, presented editing suggestions as if they came from established authors and academics—without their consent.

I'm suing Grammarly over its paid AI feature that presented editing suggestions as if they came from me - and many other writers and journalists - without consent.

State law requires consent before someone's name can be used for commercial purposes.

Indeed, our data suggests a very substantial reversal. Interestingly, Trump, _gained_ (a little) ground with high SES voters, while losing w/everyone else, more with low SES, younger, nonwhite voters.

Dismantling the fledgling harm-reduction effort, defense analysts say, is among several ways the Trump administration has reorganized national security around two principles: more aggression, less accountability

I think that there clearly has been a long term realignment around education (starting well before Trump, but setting the stage for him). But a lot of shifts in 2024 around younger and nonwhite voters seem ephemeral, and driven by the spike in the cost of living...

This is the way a lot of us would like to think we would respond to hostile questions in a Congressional hearing, but its rare to see a witness just turn the tables on a Senator like this.

Interesting paper. When science is cheap, multiverse analysis becomes the key abstraction for authors & journals to strategize for.

These results suggest its the new unit of evidence authoring & review should accommodate.

Two dose-response functions. When probabilities of exposure are not homogeneous across units,
we can only partially identify the expected average outcomes from the average outcomes by exposure — even when the exposure map is correctly specified; see Corollary 11.2 — as shown here using data from Cai et al. (2015). AFEOs by exposure (left) only partially identify the EAO curve (right). Lines indicate bounds on the EAO, with red lines being the bounds when outcomes are assumed to be monotonic under exposure levels. Error bars and bands are 95% confidence intervals.

I'm giving the upcoming Online Causal Inference Seminar, this Tuesday 11:30am Eastern.

I'll be talking about different dose–response functions you might want to estimate when treatment effects may spill over from one unit to another.

Tune in & ask questions!

An analysis of over 14 million social media posts from accounts in Canada found that 87% of conspiratorial claims come from just 100 influencers.

This minority of users impacts politics, influencing what people view as normal and leads to self-censoring to avoid attacks from conspiracy theorists.

There is a tsunami of fake social science research coming for us, and the American Sociological Association doesn’t care There are so many red flags that this system is sending up, crying out for the scholarly research enterprise to defend itself. Sadly, reader, that does not appear to be happening.

I wrote it up here, with a picture of a mockingbird, and links to data and code.
