(How) can AI help build better online spaces? ✨
Last week, 16 researchers from 8 institutions gathered in Vienna to explore exactly that question. Between the Christmas markets, the WHAT-IF team discussed how LLMs can power agent-based simulations to tackle online hostility and harmful content 👇

Misinformation research has a causality problem: lab experiments are limited; observational studies confounded.
We used causal inference on 9.9M tweets, quantifying effects in the wild while blocking backdoor paths.
Does misinfo get higher engagement? Are following discussions more emotional? 🧵

Danke @brodnig.bsky.social für das aufgreifen! #Vergewaltigungsdrohungen & wüste Beschimpfungen sind keine Seltenheit, so wie mir geht es vielen Frauen. Die Justiz darf uns den Tätern nicht schutzlos ausliefern, sie muss zumindest ernsthaft ermitteln. www.derstandard.at/story/300000...
Neuer Fall von Online-Hass: "Bedroht und alleingelassen"
Der aktuelle Fall einer Vergewaltigungsdrohung zeigt, wie erniedrigend diese Form der digitalen Gewalt gegen Frauen ist. Und wie rasch Ermittlungen enden können.
