Sticking around at APSA until Sunday? Come listen to me talk about the political economy of land tenure formalization in Cote d’Ivoire. This paper (joint with Cathy Boone) uses newly digitized administrative data to understand who goes `the last mile’ from land certification to land titling.

Yes, it is very well documented that M**k and the sneering staffers who did his bidding causes mass death all over the world, deaths that continue to mount each day that the illegal closure of USAID continues.

This piece will be incredibly valuable if---like me---you've been using Murdock's ethnographic atlas for years to measure precolonial centralization but have always wondered if there was something better. Now there is!

There's a long, bad journalistic tradition: All conservative grass-roots political movements are fascinating heartland phenomena, all progressive grass-roots political movements are ineffectual bleating. This one is written off as powered by white female college grads--the wine-moms slur, basically.

Why do so few African farmers get land titles despite easy access? Matthew Ribar's @apsrjournal article reveals: village chiefs block them in centralized countries, but push them in decentralized ones. Read clear summary by @deborah_saki on PSNow

Why Do So Few African Farmers Have Land Titles?: An APSA Public Scholarship Program Summary
In the APSA Public Scholarship Program, graduate students in political science produce summaries of new research in the American Political Science Review. This piece, written by Deborah Saki, covers the new article by Matthew K. Ribar, Stanford University, "Land, Power, and Property Rights: The Political Economy of Land Titling in Sub-Saharan Africa". In developed economies, owning land usually comes with paperwork such as a deed, a title, or some official proof of ownership.

An academic question: what's your threshold for peer-review delays that would cause you to withdraw the paper from the journal? I submitted a paper on September 17th and it's still "awaiting reviewer selection." This is absurd, right?

Really important to stress that the Crown Jewels of the US higher education system were never the Ivies or elite SLACs (other countries have equivalents of these) but the well-funded, large, cheap, and excellently staffed public state university systems bringing high quality education to the masses.

The unraveling of USAID was deliberate. Paul Martin sounded an alarm about nearly half a billion dollars in food aid, and he lost his post for it. That choice weakened the country’s own safeguards and its standing overseas. A government committed to democratic practice protects its overseers.

🚨 New paper alert 🚨 Using LLMs as data annotators, you can produce any scientific result you want. We call this **LLM Hacking**. Paper: arxiv.org/pdf/2509.08825
We present our new preprint titled "Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation".
We quantify LLM hacking risk through systematic replication of 37 diverse computational social science annotation tasks.
For these tasks, we use a combined set of 2,361 realistic hypotheses that researchers might test using these annotations.
Then, we collect 13 million LLM annotations across plausible LLM configurations.
These annotations feed into 1.4 million regressions testing the hypotheses. 
For a hypothesis with no true effect (ground truth $p > 0.05$), different LLM configurations yield conflicting conclusions.
Checkmarks indicate correct statistical conclusions matching ground truth; crosses indicate LLM hacking -- incorrect conclusions due to annotation errors.
Across all experiments, LLM hacking occurs in 31-50\% of cases even with highly capable models.
Since minor configuration changes can flip scientific conclusions, from correct to incorrect, LLM hacking can be exploited to present anything as statistically significant.
