🚨Job Alert (Deadline: Apr. 30)🚨 We're seeking a Student Research Assistant to support the ongoing research in all phases of the scientific process. See the link for more details! @dirkwulff.bsky.social, @mpib-berlin.bsky.social www.mpib-berlin.mpg.de/2016979/2025...

Extreme stances about AI and LLMs in particular (be them deflationary or inflationary) are very likely wrong, valid and certainly not good for an healthy debate. But where do they come from? We (with @giadapistilli.com) argue that common cognitive biases may play a role: osf.io/preprints/ps...
