🎉 Excited to share our new paper which was accepted to #AAAI2026!
As LLMs become increasingly used as sources of factual knowledge, we ask:
Do they perform equitably across users of different backgrounds?

🎭 How do LLMs (mis)represent culture?
🧮 How often?
🧠 Misrepresentations = missing knowledge? spoiler: NO!
At #CHI2026 we are bringing ✨TALES✨ a participatory evaluation of cultural (mis)reps & knowledge in multilingual LLM-stories for India

Potato is a great platform for researchers! Highly recommend (plus a great development team behind it)
This major release of my lab's annotation tool, Potato 2.0, was a long time in the making but I'm really excited by all the new features (and quality of life improvements). If you're doing data annotation of any kind, check it out. Need any other features? We'd love to hear from you too!
Super proud that today we're releasing Potato 2.0 - the biggest update yet to our open-source annotation platform www.potatoannotator.com 🥔
Major UI/UX improvements. Support for image, audio & video annotation. AI-powered assistance/hints/labeling. And still free 🤩
Here's some of what's new:

What should academics be doing right now?
I have been writing up some thoughts on what the research says about effective action, and what universities specifically can do.

Most LLM evals use API calls or offline inference, testing models in a memory-less silo. Our new Patterns paper shows this misses how LLMs actually behave in real user interfaces, where personalization and interaction history shape responses: arxiv.org/abs/2509.19364

This paper underscores how “misinformation” is not easily operationalized as single pieces of factually untrue content, but often takes shape through the motivated amplification of specific evidence (often true evidence) that serves to build and reinforce misleading frames.
