An interdisciplinary team of researchers at the #UniKonstanz examines how AI agents reach a consensus. The results show that artificial intelligence operates similar to people in relationship to each other – but at a significantly larger scale. Details: t1p.de/7obk7 Giordano De Marzo @dgarcia.eu ​

🚨 New preprint Do LLMs have stable dispositions measurable using instruments designed for humans? Led by @jelenameyer.bsky.social, our new preprint shows that LLM responses are driven by response bias, rendering their psychological profiles method artifacts. @dgarcia.eu @arc-mpib.bsky.social

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? 🧵

How politicians communicate shapes online discourse in ways we might overlook. Our new paper shows that their choice between a fact-based (evidence-driven) and a belief-based (sincerity-driven) honesty creates a "contagion" effect, influencing how users engage and respond. ⬇️(1/8)

Very interesting paper that is making rounds on Bluesky but please notice this issue is for *proprietary* LLMs like the OpenAI ones. Running Llama locally was remarkably stable. In general, using any kind of proprietary software, especially through an API, is bad for reproducibility.
