Good info in this Experiments newsletter, including: AI/LLM respondents, conjoints in rural development settings, repeated measure designs, & when and why to prioritize data quality over representativeness (from me and John). ⬇️ I'll send you the pdf if link is gated. :)

There's a new issue of the section newsletter out! This one's on sample considerations in experiments: professional survey-takers, LLM usage, rural contexts, and more! connect.apsanet.org/s42/newslett...

If we don’t like polarizing politicians, why do we get them? Negative partisan rhetoric gets the retweets, but not the voters New #ScienceOfPolitics podcast/transcript with Mia Costa www.niskanencenter.org/if-we-dont-l...

My book is now officially out! How Politicians Polarize introduces and documents the concept of "negative representation" – when representatives focus on the other side rather than their own. Some key findings: 🧵 www.amazon.com/How-Politici...

5/6 🧵 In @ajpseditor.bsky.social @miacosta.bsky.social & @miguelpereira.bsky.social study how occupational backgrounds shape MPs' ability to garner support for their policies. Survey experiments in 🇩🇪 🇺🇸 🇸🇪. Find some experience credibility bonus among citizens & politicians. doi.org/pbhp

Why parties can benefit from promoting occupational diversity in legislatures: Experimental evidence from three countries by Mia Costa and Miguel M. Pereira is now available in Early View. @miacosta.bsky.social @miguelpereira.bsky.social ajps.org/2025/02/26/w...

This might create incentives for elites to stoke fears about other side. But it could also result in less polarized candidates if otherwise ideological prim voters elevate other considerations. Of course this is all conditional on having a competitive general election & good info about electability

We suspect (but don't test) that this helps explain primary dynamics like Biden in 2020. This was the original motivation for the project. Fear and hatred of the other side elevates stakes of election, which in turn elevates importance of electability/elite cues about this trait in nominations

Here we show results from 2 conjoints. 1) shows marginal effect of being "likely to win" (vs lose) on vote choice based on out-party ratings, controlling for ideology alignment. 2) shows win vs. toss up, controlling for policy agreement. Electability always matters most for negative partisans

New @polbehavior.bsky.social paper with @miacosta.bsky.social. We show that voters with more negative views of the other party (negative partisans) are more likely to care about candidate electability & even willing to give up representation for better chance to win link.springer.com/article/10.1...

🚨 Now up on @APSA_Preprints, my paper w/ the great @miacosta.bsky.social on how to deal with inattentiveness in conjoint experiments. Details below! 👇 preprints.apsanet.org/engage/apsa/...

Republicans who stand up to Trump are regularly terrorized by their fellow partisans. It’s a commonly known consequence, but we don’t hear much about it.

Why do we lack parity in gender representation in Congress? One reason is "party-driven descriptive representation." Nearly half of D candidates are women compared to 1 in 6 for R's.

My first post on BlueSky. Hi! My book, HOW POLITICIANS POLARIZE, officially has a cover and I wanted to share. Coming soon in 2025 with University of Chicago Press --> press.uchicago.edu/ucp/books/bo...

Going to #APSA2024? Come check out this great panel Sunday, featuring new work by @miacosta.bsky.social & myself. In it, we offer a simple way to capture respondent inattentiveness in conjoint experiments & w/o risking post-treatment bias (CC @brendannyhan.bsky.social). Hope to see u there! polisky

Job alert: A little late to the game, but we're searching for a tenure-track assistant prof in comparative politics. We're particularly interested in scholars who study East Asia, Southeast Asia, and/or South Asia. Details: apply.interfolio.com/151639

We're hiring two data scientists in the Social Science Data and Computing Lab here at Dartmouth. New staff would work with faculty and students. MA preferred, though BA/BS + relevant skills also considered. Some remote (1-2 days a week) possible. Please share widely!
