The submission email for the workshops call is now available on the call for workshops: colmweb.org/cfw.html

New preprint! Metaphors shape how people understand politics, but measuring them (& their real-world effects) is hard. We develop a new method to measure metaphor & use it to study dehumanizing metaphor in 400K immigration tweets Link: bit.ly/4i3PGm3 #NLP #NLProc #polisky #polcom #compsocialsci 🐦🐦

New: The largest medical A.I. randomized controlled trial yet performed, enrolling >100,000 women undergoing mammography screening The use of AI led to 29% higher detection of cancer, no increase of false positives, and reduced workload compared with radiologists w/o AI thelancet.com/journals/lan...

Completely agree that eliciting human preferences is the hard part. It is unclear the current wave of agents will actually be useful.

Modern supply chains don't look like trade theory 101! They involve constant border crossings, each now hit by tariffs. Tariffs raise prices, but the more important thing they do is disrupt supply relationships. 1/

Elaborating on the metaphor of puzzle pieces. 1. AI and human intelligence are of different types (circle and square). 2. Neither is perfect. Instead of forcing AI to be human alike, it is useful to figure out how to fill in the missing piece of human intelligence required to achieve the goal.

Spent a great day at Boulder meeting new students and old colleagues. I used to take this view every day. Here are the slides for my talk titled "Alignment Beyond Human Preferences: Use Human Goals to Guide AI towards Complementary AI": chenhaot.com/talks/alignm...

I don’t really have the energy for politics right now. So I will observe without comment: Executive Order 14110 was revoked (Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence)

I hope the press will report on the investor victims of this scheme, as with last month’s Hawk Tuah meme coin speculation debacle, and not just the winner: Trump launches meme coin, apparently makes more than $25 billion overnight www.axios.com/2025/01/18/t...

PLEASE RT :) Submit to the annual Network Science and Economics Conference, the largest US event for network theory and empirical research in and adjacent to economics Deadline Jan 30 (soon!) Conference Apr 11-13 at Stanford

The Chicago Human+AI lab is now on 🦋 @chicagohai.bsky.social !

How can we design AI systems that enhance human critical thinking, reasoning, and agency, rather than diminish them? Happy to announce our workshop on "AI Enhanced Reasoning" at #CHI2025 in Yokohama on April 26, 2025. Please join us! aireasoning.media.mit.edu

We need a federal data privacy law now. Or we’ll continue down the road of a piecemeal strategy of banning popular foreign apps, while the US data broker industry continues to monetize the data of all Americans, mostly without our consent or notice. #AIBillofRights

New piece in Nature: @leahpierson.bsky.social and I argue that philanthropic funders should shield science from cuts the Trump administration may make to climate science, infectious disease, etc. Free access link: rdcu.be/d6aul Longer version on my website: shorturl.at/muwts

I've posted the practice run of my LSA keynote. My core claim is that LLMs can be useful tools for doing close linguistic analysis. I illustrate with a detailed case study, drawing on corpus evidence, targeted syntactic evaluations, and causal intervention-based analyses: youtu.be/DBorepHuKDM

Real world data (RWD) analyses need diverse expertise in medicine/stats/causality. As a result, RWD causal analysis is slow and prone to error. AI tools can help. Perspective in NEJM AI w/Maya Petersen, @amalaa.bsky.social, Chris Holmes, Mark van der Laan ai.nejm.org/stoken/defau...

Felix Hill was such an incredible mentor — and occasional cold water swimming partner — to me. He's a huge part of why I joined DeepMind and how I've come to approach research. Even a month later, it's still hard to believe he's gone.

Week 1: This year, I'll (try my best to) summarize & bring to attention one cool economic theory paper a week (so hopefully 52 in total). First up is one of my all time favorites: Bargaining and Reputation by Dilip Abreu and Faruk Gul. It is theoretical elegance, personified.

⏳ Final call! Applications for NDIF's 405b pilot program close tonight! Don’t miss the opportunity to experiment with Llama-405b and shape groundbreaking AI research infrastructure. Details below 🧵⬇️

I wish I am as organized, maybe save that for my new year resolution for the year after next.

🎉students studying AI and culture🎉 if you had an audience with senior folks from computer science, social science, and the humanities studying AI and culture, what questions would you ask them about the field, careers, skill sets, etc? students only! forms.gle/tZY5tJW2gqVd...

I've been thinking about in-context learning for nearly 3 years. While there is still plenty I don't fully understand, five papers have--to a very large extent--shaped my perspective on it, and I believe everyone should read them.

How do disparities in healthcare access affect ML models? 💰📉🧐 We found that low access to care -> worse EHR data quality -> worse ML performance in a dataset of 134k patients. Work with Anna Zink (on the faculty job market rn!) + Hongzhou Luan, presented at #ML4H2024

Reminder: The #FAccT2025 submission deadlines are roughly one month away! Abstracts are due January 15th and full papers on January 22nd. See the full CfP here: facctconference.org/2025/cfp

Announcement #1: our call for papers is up! 🎉 colmweb.org/cfp.html And excited to announce the COLM 2025 program chairs @yoavartzi.com @eunsol.bsky.social @ranjaykrishna.bsky.social and @adtraghunathan.bsky.social

Highlighting this interesting bit

Human+AI will be the future. We need to figure out how to make the world of human+AI better.

👇 Students will be using AI (heavily) whether you like it or not. The challenge for us as educators is to incorporate AI responsibly into our classroom to facilitate learning. We can have a debate on what method is best, but the response "AI is bad, don't use it" doesn't engage with reality.
