Last monday we published our paper on AI Labels and a potential spillover effect on unlabeled posts on platforms such as Instagram in the ICWSM proceedings. If you are interested in our work you can now find it here: ojs.aaai.org/index.php/IC... Huge thanks to my co-authors @ddimmery.com and Pu Yan!

🚨My first preprint is out on @socarxiv.bsky.social! How do AI-generated content labels shape what people see as authentic on social media — and do labels have unintended side effects? osf.io/preprints/so... A thread 🧵

New paper w/ @lstoetze.bsky.social "Estimating Treatment Effects on Proportions with Synthetic Controls" out in @polanalysis.bsky.social 👀 When your outcomes are compositional (such as vote shares), applying synthetic controls separately to each part can break the math. We show how to fix it: 🧵

🗓️ May 19, 3–4pm BST: I'm presenting at the DEMED webinar series on social media as a research tool, organized by @anjaneundorf.bsky.social & @aykutozturk.bsky.social I'll speak about geographic targeting using social media ads and why it matters. Sign up here: www.gla.ac.uk/research/az/...

Wow, feels like one of those papers that becomes an instant classic. That AI output isn't politically neutral is not new, but it's great to see this being demonstrated in detail - with the language-dependent effect, and the laundering mechanism through training data. Congrats to everyone involved!

I’m excited to share a new paper in Nature that shows how large language models launder the strategic rhetoric of authoritarian states. Paper here: www.nature.com/articles/s41.... A thread.

One of the most impressive examples of research happening at @hertiedatascience.bsky.social. Evidence production is a massive soft power and some governments are currently shooting themselves in the foot by attacking the very institutions that nurture it.

Sebastian Ramirez-Ruiz@seramirezruiz.bsky.social · 3mo ago

Our paper is out in Nature Human Behaviour! @rsenninger.bsky.social and I asked a simple, underexplored, question: when governments write policy documents, whose knowledge do they actually cite? 👉 rdcu.be/fhngy 🔓 seramirezruiz.github.io/papers/ramir... DOI: www.nature.com/articles/s41... 🧵👇

Ich durfte in der @taz.de ein bisschen was zu Umfragen erzählen, und was soll ich sagen - Berichte über den Tod von Umfragen sind stark übertrieben...

Yannik Achternbosch@yannikacht.bsky.social · 6mo ago

In fünf Bundesländern wird 2026 gewählt, mindestens wöchentlich gibt es neue Umfragen. Mit @simonsaysnothin.bsky.social habe ich in der @taz.de drüber gesprochen, warum wir überhaupt Umfragen machen und welche Stärken und Schwächen die haben: taz.de/Vor-den-Wahl...

Always a pleasure chatting with students who ask sharp questions 😊 Thanks to The Governance Post for having me - and yes, I stand by the autopilot line.

School council election. Also running: the class clown. Annoying to all, impossible to ignore. Kid 1: “I’ll vote for him. He’s in my class.” Kid 2: “Nice poster! He'll get my vote.” Kid 1: “Also, he promised better school lunches.” Political scientist in me: slowly nodding, checking off the 2020s
