George Pólya famously said that `it is better to solve one problem five different ways than five problems one way.' He'd be sad to learn what we found: RLVR pushes LLMs in exactly the opposite direction, toward solving each problem in just one way! 📜: arxiv.org/abs/2610.11064

Wikipedia helped make LLMs possible. Now, it is grappling with how to use them. Unlike its peers, Korean Wikipedia embraced LLMs through WikiVault: only 0.1% of editors use it, but it accounts for ~30% of new bytes! New preprint led by @inhwa.bsky.social (who's at @acm-cscw.bsky.social!!) 🧵

My research group is hiring someone based in the Chicago area. Come join us!

Everybody, everybody, we're stoked to announce Princeton SocietalAI, focused on the empirical study of genAI on the ground in science, education and beyond and on producing superior forms. Come see @alondra.bsky.social, Brian Merchant, Audrey Watters Nov. 2 at our launch event.

DoorDash has ripped off more than 260,000 NYC delivery workers. We’re making them pay $131.5 million — the largest worker settlement in City history. This is New York, where hard work pays and greed will cost you.

Congrats to Varun Rao @samanthadalal.bsky.social, Andrew Schwartz, Amna Liaqat, @dana.witchy.business, and @andresmh.com for getting an 🏅Honorable Mention Award at CSCW 2026 for “FareShare: A Tool for Labor Organizers to Estimate Lost Wages and Contest Arbitrary AI and Algorithmic Deactivations”

A new tool developed by Princeton researchers provides gig workers access to aggregate wage data that companies do not provide — a boon for rideshare labor advocates.

Okay, so I'm two and a half weeks behind, but (ht @timothychambers.net ) this is fantastic and a reminder of why *protocols* matter so much over platforms, no matter what people say about any particular site or service.

Congrats to Julia Ying on completing her undergrad thesis and graduating! 🎉 Her thesis focused on a multi-registry system for decentralized discovery and curation, exploring new power dynamics and trust mechanisms in the OpenCourier protocols. Wishing her all the best for what's next!

Is the only way we can create algorithms that people understand to make them trivially simple? We argue, no. People can predict the behavior of algorithms that are arbitrarily complex, if and only if they are available, compact and aligned. arxiv.org/abs/2601.18966

A fundamental challenge in human-robot interaction is that capabilities and limitations are often opaque to users. In our upcoming #HRI2026 paper, X-OOHRI, led by the brilliant Lauren Wang, we use AR to make robot capabilities and limits visible during object-oriented interactions 🤖

A new app developed at @princetoncitp.bsky.social allows researchers to construct a large-scale dataset that aggregates individual worker data across many thousands of rides to shed light on the working conditions of rideshare drivers.

We implemented Bonsai on Bluesky and conducted a two-phase, multi-week study with 15 participants. This deployment allowed us to observe how people used intentional feedbuilding in practice, and how it compared to their experiences with engagement-driven defaults.

In the ranking stage, Bonsai orders the curated content using criteria derived from the user’s stated intent—rather than predicted engagement—making the logic behind feed prioritization transparent and directly aligned with user goals.

In the curating stage, users can apply natural language prompts (e.g., “focus on recent policy updates” or “exclude promotional posts”) to filter and organize the sourced content, ensuring the feed reflects users' goals / preferences. Each prompt is fed into an LLM that individually ranks content.

In the sourcing stage, Bonsai gathers a wide pool of candidate posts aligned with user goals. Users can refine this stage by editing sources (adding or removing accounts, hashtags, or feeds) to shape where their feed draws content from.

In the planning stage, users express their goals in natural language (e.g., “updates on AI policy” or “posts from close colleagues”). Bonsai translates these goals into structured representations that guide the subsequent sourcing, curating, and ranking of content by providing initial suggestions.

With Bonsai, users can articulate what they want from their feeds (e.g., tracking research, staying informed on a policy area, or connecting with a community) and the system procedurally builds a feed that reflects those intentions in four steps, which we discuss below.
