We have a new version of this paper out. The headline results are the same—political science must filter results heavily for statistical significance—but we've added many extensions and rewritten much of it in response to feedback (thank you!).
A quick thread on updates 👇

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

Say I wanted ~9k USD to buy out the teaching time of a prof (a brilliant coauthor of mine) so he can work on creating a validated ground truth dataset for a challenging data extraction and labelling task that current public LLMs (e.g. GPT5) have not yet saturated. Who do I pitch?

If it feels like survey experiments are taking over top journals, you're not wrong!
19 Dec 2024
In the most recent year, about 1/5 articles in AJPS and JOP had a survey experiment. (preliminary result from work in progress with @VincentAB and @jon_mellon, come see more at SPSA)

New paper w/ @caprosser at @apsrjournal. A recent paper claim rising mass polarization in US is actually declining survey cooperation rates (only diehard partisans responding). We show evidence that this actually results from overly strong regularization

🚨 New paper out!
Excited to share this, where I take a 'weaponized interdependence' view at explaining historical failure and recent success in global tax policy - and how that view can help fight climate change and inequality🧵👇
