For 15 years, I’ve been studying 1960s civil rights protests with particular attention to how nonviolent and violent actions by activists & police influence media, elites, public opinion & voters. I'm thrilled some of that work was published last week. 1/ cambridge.org/core/journals/…

Now published at @apsrjournal. Check out "The Symbolic Politics of Housing" doi.org/10.1017/S00030554261…
New results! In "The Symbolic Politics of Housing," @dbroockman @j_kalla & I showed that public opinion about housing policies correlates w/ affect towards the groups that the policies make salient (via framing or criteria in the policy itself). 🧵/19

NEW WORKING PAPER We meta-reanalyzed a decade of candidate-choice conjoint experiments. 144 papers. 243 studies. 434K respondents. 2.18M candidate matchups. 52 countries. tl;dr: It turns out people vote based on policy... Here's what we learned:

If you're PhD-curious, join the info session I'm hosting on Oct 28 - in person or virtual. I'll be discussing what a PhD entails, what it prepares you for, and how to prepare to apply for a PhD program. My advice will be primarily focused on the social sciences. @UCBerkeley

It’s Columbus Day. What to make of it, given Indigenous peoples’ wholly merited dislike of it? In general, it's a problem when a national holiday angers millions in that nation--especially when the reason for the anger has nothing to do with the reason for the holiday. 1/n

Thought experiment: If every block of single-family homes in Palo Alto was owned by a single investor (who rented out the housing), would they still be blocks of single family homes?
One thing I believe firmly is that the YIMBY/NIMBY problems we have today are directly equivalent to the land fragmentation problems – and related political economy issues – that essentially all societies faced in their agrarian past. To begin with, homeownership is literally landownership in nearly all cases other than a few mass leaseholder locations like Singapore, Hong Kong, Britain before 1960, and Canberra, Australia. Second, it is 'splintered' or 'fragmented' into many different plots. In an important sense, the crazy cadastral maps of, say, Galicia in Northwestern Spain, look like the standard property lot maps in most countries today. Third, there are an enormous number of customary rules and rights governing how the land can be used. Farm life has always been partly communal, varying by crop, location, population density, and so on. To insure against bad years wiping them out, farmers owned (or had lease/copyholds on) strips across many fields. Strips were cultivated individually but rotations were coordinated collectively. Ox teams were shared. This is inevitable. So too today do we have land use rules that are designed to express the interest of the broader community, ranging from rules preventing me from extracting oil, tanning leather, or blasting music at all hours, to rules preventing me from knocking my property down to replace it with a giant block, shading all my neighbours, from housing dozens of extra people on my property, or even in some places just against making my house ugly enough to bother people. As @mattyglesias, @ProfSchleich, @nicholas_bagley, Bill Fischel, @CSElmendorf, @LawHeller, @RickHills2 & others have written, we need simpler, arguably more American property rights, the kinds of property rights that most European countries attained only after centuries of difficult reform. And I think we should look to those centuries of reform as a guide to what might be possible.

🚨New Paper🚨The Great American Property Tax Freakout! Since 2024, many states have radically reshaped their property tax systems. The changes are an example of the national trend of carving out influential groups from taxation, in this case a majority group: homeowners. (1/16?)

Mayor @DanielLurie, the gauntlet is thrown: "cities like Raleigh typically *finish* construction [of a housing project] before cities like San Francisco even approve it." Check out this new work from a crack team of @Princeton and @UChicago economists ⤵️.
Where in America can new homes get permitted and built fastest? And are we getting faster or slower over time? In a new paper with @leonardo_damico and Audrey Wang, we show cities like Raleigh typically *finish* construction before cities like San Francisco even approve it.

Teaching R and stats to complete beginners using Data Analysis for Social Science (DSS)? Just revised my syllabus — find it here: ellaudet.github.io/dss_instr… New and improved self-graded review exercises coming soon — stay tuned! #rstats
My textbook with Kosuke Imai (@Harvard) is finally out! Assuming no prior knowledge of statistics or coding and only minimal knowledge of math, DSS teaches the fundamentals of survey research, predictive models, and causal inference + how to analyze real-world data with R. 🧵..

Health outcomes in the USA are increasingly politically polarized. Declining trust in medical professionals among right-leaning individuals, including lower willingness to seek care, follow clinical advice or believe in medication effectiveness (even for issues unrelated to COVID-19) is leaving conservatives vulnerable to preventable health risks. nature.com/articles/s41562-0…

New paper with Alec Ewig, conditionally accepted at Political Analysis: Retrieval-Augmented Representation. Most research evaluates the link between elected officials and citizens on highly salient policies. But what if concerns are systematically excluded from the agenda?

Hey @Hyatt Your hotel has now refused to lower the shower toiletries for me. They said “the ADA only requires the hotel accommodate guests staying in the #ADA accessible rooms.” That is NOT how Title III works. Accommodations don’t start and end with a specific hotel room.

My first-ever solo-authored paper is out today in @JournalREP! What drives Americans to switch their presidential vote based on race over the last 3 elections? I show that it's not general racial warmth, it's changing beliefs about discrimination. (🧵 1/3)

Quoted in this weekend’s New York Times on AI and elections. The challenge for AI companies: curating balanced, high-quality information while avoiding the appearance of playing favorites. With AI slop flooding the zone, doing nothing is costly. Gift link below.
