I’m excited to share this paper, which I wrote together with @schneali.bsky.social, @corneliabetsch.bsky.social & @laulilleholt.bsky.social (1/5)
LLMs have been widely reported as left-wing biased. The finding has shaped policy and debate — with Trump banning "Woke AI".
Our new paper challenges this story.

New paper with @tadegquillien.bsky.social and Azzurra Ruggeri: "Children seek out observations that can reveal a partner's generosity". Out in @humbehevosoc.bsky.social EHB: www.sciencedirect.com/science/arti... 🧵
Far too long in the making.. but finally out in #AnimalBehaviour @asab.org:
