Is AI biased against some demographic groups? 🤔 Recent LLM audits disagree, finding both ➕ and ➖ discrimination, even for the same models. In a new paper, accepted at #EMNLP2026 Findings, I show that this disagreement can arise from differences in audit format! 🧵 (1/7)

I was interviewed on CBC's Cost of Living podcast about how crowdfunding is increasingly used to cover everyday expenses like rent, groceries, and utilities. A lesson from the research is that it's especially hard to raise money this way for ongoing costs, compared to one-and-done projects.

Can crowdfunding solve the cost of living crisis?

Um, ok... This paper forthcoming at the JOP provides evidence that rent control in Germany actually made tenants MASSIVELY *less* NIMBY. This result was in the opposite direction of the authors' pre-registered expectations. And the effect sizes are, truly, massive.

When a man hijacked a bus in Hamilton, Ontario, on Tuesday, the potentially catastrophic scenario ended happily. It turns out he was a pretty decent bus driver. He made regular stops to pick up passengers, the police reported. At one point someone tried to board with an expired bus pass. No dice.

A Man Took a Bus for a Joyride. Turns Out, He’s Not a Bad Driver.

The incident in Hamilton, Ontario, ended safely with an arrest and no injuries (and all fares paid).

@martinlukk.bsky.social @kenworthy.bsky.social, Erik Schneiderhan, and I pull together threads from our recent books on donation-based crowdfunding in the Journal of Philanthropy. We argue that rather than being a disruptive new force for good, crowdfunding's benefits have been greatly overstated.

Disrupting Philanthropy? A Reality Check for Digital Crowdfunding

Crowdfunding promised to revolutionize philanthropy by using digital technology to make charitable giving cheaper, easier, and more accessible. Has this been realized in practice? We highlight three ...

I’m delighted to share that the August 2025 special issue of Sociological Methods & Research on Generative AI is out now. Along with my co-editor, Daniel Karell, we put together this issue to build on the conference we organized last year. Here's a thread on each of the ten papers:

So I don't have the energy to redo the entire thread about the papal conclave but I will redo the part about the Latin nerdery: the announcement of a new pope is always in Latin, and uses a very traditional form.

Because Ezra Klein and Derek Thompson's "Abundance" is less a book than a discourse-generating machine (by design), I'm going to review the *reviews* (I also have a review of the actual book coming, I'm not a total weirdo). Roughly from worst to best:

Hello, #ESS2025! I'll be presenting tomorrow, Friday at the "From Polarization to Solidarity" mini-conference. Whittier, 4th floor @ 8AM. Come to find out what this map tells us about territorial identification in contemporary Europe!

As reported, the entire staff of 538 was laid off this morning. This is a severe blow to political data journalism, and I feel for my colleagues. Readers note: As we were instructed not to publish any new content, all planned updates to polls data and averages are canceled indefinitely. Huge loss :(
