Move fast, break things. apnews.com/article/open... Even if their recent push has largely fixed this issue openai.com/index/streng... Can't help but think why they didn't push earlier...

Canadian researchers should be aware the there is a motion before the Parliamentary Standing Committee on Science and Research to force Tricouncils to hand over disaggregated peer review data on all applications: Applicant names, profiles, demographics Reviewers names, profiles, comments, and scores

If you don't think rando MPs (and whoever else they share it with) should have access to personal information of individual applicants, reviewers, and students, confidential data, & full applications and reviews in every Canadian research grant (funded or not), please sign.

Had an amazing time at #COLM2025 It was vibrant, high level, and seemed a healthy balance of LLM critique and solution focussed. I am so happy with how our social simulation workshop went. Chairing and panel moderating was a pleasure thanks to the many that participated. Stay tuned for recordings!

Excited to be at #COLM2025 and to be organizing one of (perhaps the?) first workshop on social modelling with LLMs! Looking forward to this community-wide stocktake on the state of the field, main challenges, and promising applications! sites.google.com/view/social-...

Looks like I missed the publication of another stochastic thermodynamics text in June. Seifert is arguably better positioned, but let's see about his exposition style. The other text is Politi & Pigolotti, which was nice, but light on the info side. www.cambridge.org/core/books/s...

I am recruiting (Canadian🇨🇦) graduate students at York University for Fall 2026 in Social and Personality Psychology! If you are interested in misinformation, political polarization, and/or computational social science, I'd love to hear from you. Feel free to reach out with any questions.

It seems obvious that we should prioritize addressing misinformation that is more harmful. But what makes something more likely to be harmful? Can we can reason about it before the harm has occurred? 📣 In an upcoming #CSCW2024 paper, we present a taxonomy of *Misinformation as a Harm* ➡️

If there is anything worse than "economist brain", it's economist brain arguments about how inefficient the state is.

Ironic how that last sentance in the image (as a belief) is a deeply held fiction for certain individuals ('deep state is after me') who voted for a govmnt that's doing just that to other people whose idealistic notion of govmnt presumably made them not believe it could happen, least of all to them.

Interesting analysis that reminds me that political discourse is a technology of control in democracy that is used to stabilize ideologies.

I don't like where this is going...the distinction is nuance and the modern media bit just isn't equipped for nuance.

A fun reminder that a loss of 60,000 jobs in and around academia is ~50% more than all coal mining jobs in the entire country.

Motherfucking wind farms…

Listings! Bring them back!! (Also a wonderful love letter to NYC at a certain formative time.)

Most of the internet used to be like this. This is actually the default, it took companies enclosing the internet and adding weird, soul-killing incentives to make people behave the way they do now. In a way, there is truly nothing special about Wikipedia except that it survived longer.

If you are interested in a unified collection of common misinformation detection benchmarks, check out our recent repo @hf.co

💡 Strong data and eval are essential for real-world progress. In "A Guide to Misinformation Detection Data and Evaluation"—to be presented at KDD 2025—we conduct the largest survey to date in this domain: 75 datasets curated, 45 accessible ones analyzed in depth. Key findings👇

Frictionless reproducibility practices are coming to misinfo detection research. Much needed!

Every time I see how long mypy runs I think how could it be that slow so a 600x speedup checks out.

1B up in smoke in 1 month. 3 more months of this and that's the entire proposed NSF budget.

Because we must build good things while we scream about the bad, I have started a "Data for Good" team @data-for-good-team.bsky.social that partners with organizations needing short-term data science help. We have three projects ongoing & will add more as our capacity grows. data-for-good-team.org

Oh fuck off. America has always been awash in get-rich-quick scams and we don’t need to treat this one with emotional heft because it takes place on the computer. Stop painting these people as anything other than credulous rubes or you’re going to encourage them.

I like Carney for this moment but I agree with Zeke's thread here that long-term, what matters is that we have bought more time to build an effective response against illiberal, co-opted politics.

Seeing Like a Platform has arrived in physical form! 😮 Of everything I've ever written, this is probably the work I'm most proud of. And it's free to read! www.seeinglikeaplatform.com Would love to hear your thoughts!

You know he is just itching to brag about all the money he is personally making (the deals!). It would be hilarious (actually more tragedy ofc) if he can't keep his trap shut and explicitly mentions some of them by accident. At this point, it wouldn't be too surprising tbh.

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

There’s a lesson here for every Big Law firm, university and media company if they care to learn it.

While I think the UHN initiative is wise, currently our ecosystem is zero sum. E.g. our system rewards success via association of CRCs to grant funding. How many other institutions have these resources and what will the impact be? Methinks more concentration. Not necessarily a good thing. /2

How about just the beginning of the end of overall dominance of American universities? Imo it's really one of the golden egg laying geese that keeps the US where it is. Not to mention being the most productive and powerful knowledge-generating system humans have ever come up with.

It’s time your government got back in the business of building affordable homes.

Super excited to share our paper, Simplifying Deep Temporal Difference Learning has been accepted as a spotlight at ICLR! My fab collaborator Matteo Gallici and I have written a three part blog on the work, so stay tuned for that! :) @flair-ox.bsky.social arxiv.org/pdf/2407.04811

very excited for this...and in my hometown to boot.

capital interests in aggregate may be stabilizing (ie. they will act strongly to avoid massive, across-the-board capital destruction) in unipolar settings where everyone assumes they are strongly coupled into the system. Autocratic rule (typically falsely) promises self-interest a way to get ahead.
