Have any academic researchers been able to get access to Reddit data through their new "Responisble Builder Policy" and approval process? www.reddit.com/r/redditdev/...

I gave a talk at Princeton about LLMs in the online social world - the video is now up at www.youtube.com/watch?v=ITjI... Slides are at jeremydfoote.com/presentation...

CPSC Warns Consumers to Immediately Stop Using Batteries for E-Bikes from Rad Power Bikes Due to Fire Hazard; Risk of Serious Injury or Death www.cpsc.gov/Warnings/202...

What's the most clichéd academic paper title template? It has to be "Mind the .* Gap", right?

Another quick thought about LLMs: In the real world, we should always assume that "exponential" growth curves are actually logistic curves. That is, anything that connects to the real world will eventually be resource constrained in some way, and growth will slow...

A hopeful thought about LLMs: Because they involve sharing information between people, they will always require moderation, servers, etc. These needs lead to some level of centralization (and in practice, corporate ownership). LLMs are different—very capable models can already be run on a laptop..

new paper by Sean Westwood: With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

Join the CDSC on Nov. 7th for our next Community Dialogue! Northwestern Student Matt Gaughan and Dr. Igor Steinmacher will discuss how FLOSS projects adapt their work processes to recruit new contributors and build the project communities that they want. Learn more and register:

There once was a man named Oz'mandias, Who had thought that he was the grandiest. "Look on me and despair" But now nobody cares And nothing remains but the sandy dust.

This morning, I’m at the CSCW conference in a session on “Activism in a Time if Data.” Most of the papers seem to assume activism for “good,” ending with design recs for supporting activism. As far as I can tell, none of the papers center right wing activism. Seems like we have a massive blind spot.

so sick of the explore-exploit dilemma, how about something new?

If you've ever wanted to learn how to make beautiful websites with #QuartoPub and #rstats , check out this workshop I'm giving in a couple weeks! It'll be a blast (and we're covering Quarto's brand new _brand dot yaml system!)

I'm teaching a proseminar this semester for new PhD students. We're reading @jessicacalarco.com's great book, "A Field Guide to Grad School" & we're talking about academic jargon tomorrow. What's some academic jargon you took a long time to understand? Any weird jargon I should share with students?

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

Thinking about applying to grad school? Wonder what it’s like to pursue a PhD or MS? Interested in the intersect of technology and society? CDSC is hosting a Q&A session for prospective students on Sept. 26th at 12pm CT. Learn more and register here: blog.communitydata.science/prospective-...

I am recruiting PhD students this year! Our research group is holding an info session in a few weeks - details are at blog.communitydata.science/prospective-... , including a sign-up link.

Illustrating the first point: the talk is by Korean man who works at a British university, he's presenting ideas based on previous work by American thinkers, speaking at a Dutch university, to an audience from around the world. The casual cosmopolitanism of academia is striking to me in these times.

I'm thinking a lot about the debate around whether LMs can "understand." Enter a new thought experiment I call "the lean Chinese room." IMO, it shows how the pressure of compression and speed blurs the line between symbol-shuffling and understanding. doomscrollingbabel.manoel.xyz/p/the-lean-c...

I'm co-organizing #CSCW NE, an in-person regional gathering for people in Northeast America, alongside some folks from Stevens, Rutgers, and Princeton. If you want to come hang out (especially if you can't make it out to the full conference in Bergen this year), RSVP at cscw-ne.hci.social!

Perfect weather for freshman move in day 😐

Just read this incredible paper by @s0hw.bsky.social & @jeremydfoote.com: Why Do People Participate in Small Online Communities? The authors question the assumption that growth is always good, and instead show many benefits of small online communities. Highly recommended! dl.acm.org/doi/10.1145/...

Last day of summer for the kids. Quick trip to Indiana Dunes.

I am fascinated with how people come to such different beliefs about the world. In our new paper, led by Tiwalade Adekunle, we used @lauraknelson.bsky.social's computational grounded theory to compare how a pro-masking subreddit and an anti-masking subreddit talked about risks during COVID. 1/

We just posted an interactive on changes in approval for Trump from right before he was inaugurated to the present. We have very large samples (30k), and the interactive allows you to look at changes within very small slices of the public. www.chip50.org/blog/whose-a...

IMO, one of the most important ideas from social networks is that our social world is not an agreed upon fact but is perceived differently by different people and those perceptions matter. I loved working on this project led by @kyosuketanaka.bsky.social , who is an expert in network perceptions.

Attn #ICA25 tragically I lost an earring in the Hyatt Regency. It is a very cool earring. No reward except good karma but do let me know if you find it. :)

This session on causal inference was very good with some well-designed studies. We should do more causal inference! #ica25

If you'll allow me to say it, The Onion is cooking with gas today.

My new students brainstorming some project ideas

The cruelty in today's politics feels horribly corrosive. Bringing up that hard-working immigrant families — undocumented, yes, but not violent criminals — are being ripped apart based on immigration status doesn't bring compassion or even pause, but gleeful cheers.

I presented a poster at @netsciconf.bsky.social on legal co-citational networks! Lots of wonderful colleagues, intellectually stimulating discussions and a congenial environment that made me feel at home. Even street lights were… network-like! #netsci2025

I'm heading to ICA in a few weeks - would love to catch up with folks who are there.

I wrote a chapter on a functionalist account of social identity. IMO, thinking about identity in an instrumental way helps explain a lot of behavior that seems otherwise baffling. osf.io/preprints/ps...

On the verge of declaring defeat with chatgpt in my asynchronous online dataviz class. Something changed this semester compared to past ones and SO MANY assignments are essentially 100% LLM output.

People tend to dismiss VP Pence’s actions on J6: he was just doing his job, why should he get any credit for simply sticking to the letter of the law? But if it was so easy to do, why was he one of the very few in his party to do it? apnews.com/article/penc...

#Purdue folks - every 5 years or so I figure out how to parse the new version of the academic calendar website so that I can import it into Google Calendar. If you want it, I believe this link should let you view and subscribe to the calendar - calendar.google.com/calendar/emb...

For the last 3 yrs, I was the director for the Science of Science program at the NSF. We funded projects on science communication - science communication to the public, communication of public priorities to scientists, citizens engagement & participation in science. 🧵

I was really hoping that Mitch Daniels would come out with a principled take about how protecting free speech on universities means protecting even speech we disagree with. Instead... www.washingtonpost.com/opinions/202...
