Very lucky to have been able to collaborate on this Annual Review piece on luck with @fabriberna.bsky.social, William Foley and @l-sage.bsky.social. We propose that the role of luck in life can be upper-bounded with machine learning and lower-bounded by adding up causal effects of random events.

Social media often functions like a funhouse mirror, amplifying the most extreme voices who dominate online discourse. As a result, people come to falsely believe those voices represent society and public opinion far more than they actually do: www.sciencedirect.com/science/arti...

We have a new paper out in PNAS. Susanna’s thread outlines our findings. The big picture takeaway is that well-designed climate education (active, personally relevant, science-based) can complement fiscal and regulatory instruments by building public support for ambitious policy!

Who produces hate speech? And how does that matter for content moderation? We show that across different countries and platforms, a relatively small share of users are responsible for a very large share of hate - overall, 5% write 83-100% of hateful content. www.cambridge.org/core/journal...

When you see "AI-generated" on Instagram, does it make you more skeptical – or more trusting of everything without a label? New research from German Instagram users has answers for policymakers pushing for AI labeling laws. Good news and a warning👇

n/n This is relevant now: the EU AI Act's labeling requirements enter into force August 2026. Our findings suggest coverage matters. Partial labeling has trade-offs that policymakers should consider. Feedback welcome! :)
000
Fabian Pawelczyk @fpawel.bsky.social · 12/02/2026
5/n This matters because full labeling coverage is unlikely in real-world settings. If some content is labeled and some isn’t, users may update how they interpret unlabeled posts by comparison.
000
Fabian Pawelczyk @fpawel.bsky.social · 12/02/2026
4/n But there’s a catch. We also find an _implied authenticity effect_: exposure to labeled images slightly increased perceived authenticity of _unlabeled_ content (≈ 1/5 the size of the direct effect).
000
Fabian Pawelczyk @fpawel.bsky.social · 12/02/2026
3/n Main result: Labels work. Both labeling strategies significantly reduced perceived authenticity of AI-generated images (≈ 0.27 SD). So far, so good.
000
Fabian Pawelczyk @fpawel.bsky.social · 12/02/2026
2/n We ran a pre-registered survey experiment with a _German_ sample (N = 877). Participants saw Instagram-style posts with: • no labels • a process-based label (“AI-generated”) • a harm-based label (“Misleading”)
000
Fabian Pawelczyk @fpawel.bsky.social · 12/02/2026
1/n Motivated by new regulations requiring disclosure of AI-generated media, me and my co-authors @ddimmery.com and Pu Yan (Peking University) ask two questions: 1️⃣ Do AI labels reduce perceived authenticity of AI images? 2️⃣ Do labels affect how people judge _unlabeled_ content?

This seems to be very interesting. But I don’t really understand how you can make this claim based on the two observations from the former point. I’d assume that speeches with more media coverage go along with higher stakes and therefore different vocal styles?
