Thanks to Mirta Galesic and Henrik Olsson for inviting me to the impressive @csh.ac.at in Vienna, where I could present my research under the bold title "The complexity of Platform Power" and have inspiring and interdisciplinary discussions all day!

🚨New preprint! 🚨 "Boosting metacognition in entangled human-AI interaction to navigate cognitive-behavioral drift" arxiv.org/pdf/2602.01959 Happy to see this new work coming to the surface alongside @cabels18.bsky.social @lorenzspreen.bsky.social @lewan.bsky.social and @stefanherzog.bsky.social 🧵

Great location to be in:

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

This fits still: youtu.be/7j4QIayjAaY?... English: youtu.be/Qvum2HzocWs?...

We should view Social Media as a systemic issue instead of a symptomatic one and tackle its root: Overcoming the commercial and exploitative logic we applied to digitalization so far. Making social media better and safer for eyeryone will be more sustainable for young people AND for democracy.

Apply as a supervisor until February 10! If you are a PhD student or postdoc working on topics related to this year's theme of 'Psychological Science in a Digital Age: From Individual Well-Being to Societal Processes', this opportunity could be perfect for you! 🚀

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉 We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟 Link: www.science.org/doi/10.1126/... (contact me for open access)

Die #Algorithmen vieler #SocialMedia - Plattformen belohnen Aufregung. Desinformation, Hass und Hetze dominieren. Zerstört das Internet die #Demokratie? Darüber spricht Ralph Hertwig @mpib-berlin.bsky.social im Podcast "Nur eine Frage" 🎧 Eine Hörempfehlung -> www.zeit.de/wissen/2026-... @zeit.de

So great to see this published now! Have been a big fan of the ice-fishing project all along, by @alexschakowski.bsky.social @ralfkurvers.bsky.social and many others! 👏👇

This is still really irritating me because the response to a rumor like this in 2026 shouldn’t be to write a “Users say” article. We should have the ability to audit or investigate such claims and we don’t, and that is due to failure by the United States Congress to pass basic transparency laws.

Just in: EU Commission is opening a new investigation into Grok’s nudification tool on X under the DSA. “This includes risks related to the dissemination of illegal content in the EU, such as manipulated sexually explicit images, including content that may amount to child sexual abuse material.”

Kai's write up and @cailinmeister.bsky.social's thread do a great job of summarizing our results. Rather than cover them a third time, I thought I'd clarify some misconceptions over our piece and COIS more broadly that keep cropping up scattered across replies. 🧵🧪

Some coverage of our new findings, with perspectives and thoughts from @shelbygrossman.bsky.social, @cailinmeister.bsky.social, @naomioreskes.bsky.social, and @profsanderlinden.bsky.social

"Online hate and disinformation do not have easy solutions. But the Trump administration’s lies are not about free speech. They are about power – [...] promoting its far-right allies in Europe, and protecting its partners in Big Tech." @davidakaye.bsky.social www.techpolicy.press/the-trump-li...

The Trump admin’s censorship agenda is chilling & relentless. I counted 200+ attempts in 2025 to muzzle press, protesters, public servants, judges, law firms, universities, corporations. But resistance has blunted this campaign & we must fiercely defend free speech: www.nytimes.com/2025/12/31/o...

We got Meta’s “general global playbook” for defeating advertiser verification regulations, which the company knows would reduce scams. It includes making scam ads “not findable” for regulators searching Meta’s ad library through targeted scrubbing. www.reuters.com/investigatio...

Full solidarity with @hateaid.org ! Standing up for our rights online is the way to go, and these accusations couldn't be more Orwellian... all the more reason to keep going this way and push for the DSA and transparency from online platforms!

Krass: Die US-Regierung hat Sanktionen gegen Anna-Lena von Hodenberg und Josephine Ballon von @hateaid.org erlassen, dazu trifft es auch den früheren EU-Kommissar Thierry Breton, weil "These radical activists and weaponized NGOs have advanced censorship crackdowns by foreign states".
