Really excited about this paper. Part of our continued efforts to make sense of what ML models are and aren’t doing.

Honest people don’t lie. Or do they? Liars aren’t honest. Or are they? One puzzling conundrum in contemporary politics is that politicians who seem to be estranged from facts and evidence are nonetheless considered honest by their followers. 1/n

An incredible opportunity for the right person: The Santa Fe Institute is seeking applications for full-time resident faculty positions at all academic levels For me, this has been the best possible job ever. More info here: santafe.edu/about/jobs/r...

For those who didn't make it to #ASSA2025: strongly recommend @sendhil.bsky.social's AEA distinguished lecture, available at www.aeaweb.org/webcasts/202... (starting at minute 16)!

Very interesting interview with @sendhil.bsky.social on AI. Fresh perspective on several topics, including value of AI in education. youtu.be/z_svj3NP968

What happens when @sendhil.bsky.social and David Yanagizawa-Drott come together to discuss AI? In this inaugural episode of 'Thought Supply' the conversation moves beyond the buzzwords to explore the profound economic implications. Premiering Dec 13 8pm CET youtu.be/z_svj3NP968 #EconomicsForSociety

🔖 Looking forward to digging into the latest working paper from Jens Ludwig, @sendhil.bsky.social and Ashesh Rambachan on the use of LLMs in economics research. #econsky #scisky #phdsky arxiv.org/abs/2412.070...

Economic valuations fluctuate in ways empirical research cannot fully explain What information are we missing? Economic theories emphasize the role of hard-to-quantify beliefs and perceptions My job market paper develops algorithms + measurement to quantify perceptions of firms

To researchers doing LLM evaluation: prompting is *not a substitute* for direct probability measurements. Check out the camera-ready version of our work, to appear at EMNLP 2023! (w/ @rplevy.bsky.social) Paper: arxiv.org/abs/2305.13264 Original thread: twitter.com/_jennhu/stat...
