"Do not panic or hallucinate like a fragile Large Language Model."

We have a new paper out! We asked a simple question about Long COVID “phenotypes": if you take the same patients and the same symptoms but run different clustering algorithms, do you get the same patient subgroups? Short answer: no. 🧵 #LongCovid 1/

There, I will be joining the Cooperative Systems and Intelligence Lab under @xuanalogue.bsky.social, where we will work on cool new projects at the intersection of cooperative intelligence/AI alignment and cultural evolution. Onwards to glory!

I am happy to announce that I have successfully defended my dissertation --- under the supervision of my mentor @psmaldino.bsky.social --- for the title of Doctor of Philosophy in Cognitive and Information Sciences at the University of California, Merced.

Looking forward to catching up with AI safety/alignment folks and giving a couple of talks at the Center for Human-Compatible AI workshop this week! Also back in Cambridge/Boston after the workshop until early July, if anyone wants to chat :)

Back in Cambridge for a research visit to MIT! Happy to meet and chat with folks who are in town :)

🧵🧵🧵 At this point, I think it's only reasonable to fully expect some sort of major and unpleasant AI-caused economic disruption and popular backlash in the next year or two. I'm just not sure which kind.

If you're a late-stage PhD student or post-doc in computer science, and want a free trip to Singapore / NUS, consider applying for this prize: comp.nus.edu.sg/research/nus... Probably helps if you're considering a faculty job at NUS or other universities in Singapore!

I spent the last 2 months trying to prevent this. If OpenAI offered a fig leaf, Google said "imagine we offered a fig leaf." Google affirms it can't veto usage, commits to modify safety filters at government request, & aspirational language with no legal restrictions. Shameful.

Happy Trans Day of Visibility! 🏳️‍⚧️ This is my first TDoV since moving back to Singapore, and the 12th since I began my transition. It's been a long and sometimes difficult journey, but somehow I've ended up as the first (to my knowledge) publicly out trans professor in the Singaporean academy (cont.)

@rikiwilchins.bsky.social 2026 Mar 18 Advocate MIT physics student ordered to vacate campus housing before graduation after his family cut him off financially for coming out as trans raises $85K on GoFundMe in days.

Publishers say they’re blocking the Internet Archive because of AI scraping. But shutting out a nonprofit library won’t stop AI—it will damage the public’s best record of the web.

frog on the floorrrr where'd he come from nobody knows where he'll goooo

Check out this recent @nature.com paper reporting a field experiment on X. It shows X's algorithm boosts conservative content and downranks traditional media—shifting users’ views on key issues. Switching to chronological doesn’t reverse the effect. www.nature.com/articles/s41...

just had my first encounter with rice weevils that I recall being aware of, and I am simultaneously upset at the fact that: - there were bugs suddenly crawling out of my rice - I have probably already eaten them previously - apparently this is not especially uncommon with rice bought here 😖

this prompted me to reread my 1st year college essay on whether proper names w diff. referents are more like indexicals ("I", etc.) vs. homonyms, and I totally forgot I made all these crazy diagrams despite not having taken a philosophy class before truly doomed to be analytic-philosophy-brained 😅

Finally bought my first actual copy of "AI: A Modern Approach" (as a reference for the lab) and it's cool to see that assistance games have their own section now! cc: @dhadfieldmenell.bsky.social

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...

as I'm revising my course materials, I keep stumbling upon cool @mc-stan.org developments. Current favorites: 1. your model has funnels and you exhausted reparametrization ideas: metric = "dense_e" makes your HMC learn about covariance btw parameters. Sloooow, but effective! 1/

Incidentally I think one strong piece of evidence for the theory that (many) emotional expressions and their associated concepts are learned rather than innate is the ever-expanding set of Slack/Discord/etc emoji reactions.

I was curious whether people have developed "rational models" of emotional expression, and it looks like there's a very recent paper on the topic! By @yyangteoh.bsky.social and @cendripetalfrce.bsky.social.

Happy to finally see this paper (w/ @cendripetalfrce.bsky.social) out now @commspsychol.nature.com We built a computational framework to show people flexibly balance communicative benefits against social costs when deciding whether and how to express their emotions. www.nature.com/articles/s44...

One of the earlier feminist lessons I had to learn in life was how to cut off friendships with sexual abusers (+ their friend groups). I unfortunately had to learn this in high school, but with all the Epstein stuff coming out, I'm reminded that most haven't learned this at all.

in which my students explain the context-sensitivity of social roles and norms 😅

I'd like to say something about ICE, but what if they review my social media history the next time I apply for an ESTA, decide my wokeness will destroy America, and shoot me 10 times dead when I next cross the border? Can't really blame them 🤷🏻‍♀️

watched Ed Feigenbaum talk at #AAAI2026 and apparently the way he got into AI research was kinda like mine --- got bored as an elec. eng. freshman, took a class on "Ideas & Social Change", which led to studying with Herbert Simon on Math. Models in the Social Sciences, and hence, AI!

Just walked past a NUS student dance group doing warmups to a ballroom / vogue track, Ha Dub and all, and frankly I'm confused how the gayest possible dance music has become this globally mainstream.

I regret to report that the AI ads have spread to HK airport.

This is an important negative reality. It's also sustained by industry incentives—and the thing most likely to break it is a big company or two deciding it's bad business to network on a competitor's site. I am a fan of banning mean bsky account FlameTroll420, but that's not the tipping point.

love listening to a random Vivaldi mandolin concerto for the "first" time, finding the motif strangely familiar, then realizing I actually first heard it as a sample of a Yo-Yo Ma cello cover in a 90s hip-hop album

Guardian reports how misgendering can affect mental health when the victim is cis. Doesn't seem so bothered when it happens to trans people. www.theguardian.com/world/2026/j...

Again I find it baffling to compare the coverage to when Gemini generated implausibly many Black hockey players etc. That was apparently a societal emergency. But the mass harassment campaign taking place in public barely warrants a mention.

I know this is yesterday’s news and feels relatively unimportant now but just want to note that this is ongoing and X and xAI continue to do absolutely nothing about it despite being able to end it by pressing a single button.

I've recently been reading LeGuin's Hainish cycle, and finding that I appreciate how the Ekumen (a planetary confederation) goes about cultural change / intervention more than what happens in Banks' Culture novels. I think a lot of that is do with LeGuin's feminism and how it influences her work.

Marco Rubio is reportedly saying Maduro will stand trial in US courts. Which means it’s now the US administration’s position that US courts can hold foreign presidents, but not the US president, accountable for crimes.

Mods are asleep, post blobby Qing dynasty cats

This week's #PaperILike is "Elephants Don't Pack Groceries: Robot Task Planning for Low Entropy Belief States" (Adu-Bredu, RAL 2022). Love the focus on planning with "low entropy beliefs" -- not full-fledged POMDPs, but also not full observability. PDF: arxiv.org/abs/2011.09105

watching Shiva Baby when you awkwardly know some Yiddish from a previous r/s that your current (Jewish) partner doesn't character: he's married to a shiksa princess. poor guy. gf: what's a shiksa again...? me: ...it's me, I'm a shiksa.

have to say that having received hatemail from someone not entirely well who paranoidly believes I stole their research ideas, the whole Brown + MIT prof shooting is a little jarring

really can't do psychology research in the US like this any more, I see now why one must Make American Science Great Again

Grading and googling hallucinated citations, as one does nowadays, and now that LLMs have been around for a while, I've discovered new horrors: hallucinated journals are now appearing in Google Scholar with dozens of citations bc so many people are citing these fake things
