Ich wusste ja, dass es exakt so kommen wird. Aber es ist wirklich extrem, das aktuell zu beobachten und am schlimmsten ist, wieviele Leute sich dafür instrumentalisieren lassen.

New paper out in @journalqd.bsky.social led by @fgais.bsky.social with @dscheykopp.bsky.social! We map news sharing patterns of social media users and find ideological asymmetries, but no outlet fragmentation.

In ihrem aktuellen FAZ-Gastbeitrag beklagt Katherina Reiche eine "Selbsttäuschunug" in der Energiepolitik. Tatsächlich fällt der Täuschungsvorwurf aber teilweise auf sie selbst zurück, denn der Text enthält diverse falsche oder irreführende Zahlen. Ein Thread. (1/17) www.faz.net/aktuell/wirt...

Christmas came early this year! Very happy to see our paper out in Science Advances. Led by @lfoswaldo.bsky.social, we ran a unique collective field-experiment on Reddit, to better understand who is participating in online debates and why. Paper: www.science.org/doi/10.1126/... And more below 👇

Love this. In his “I Agree” installation Dima Yarovinsky-Yahel took the content from terms of service statements for companies like Facebook, Snapchat, Instagram, Tinder and printed them out on A4 paper with a standard font size for legal contracts to demonstrate the length of these agreements.

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic.

What we’re witnessing in America is what happens when disordered discourse captures a political party, then the state itself. The Republican Party was the first to fall - abandoning truth for conspiracy, ideology for grievance, and policy for performative outrage.
