It’s great that @economist.com is talking about our paper in their piece on “slop” as word of the year — not so great that they don’t cite/link to it… www.economist.com/culture/2025...

I got an email yesterday afternoon that my NSF SPRF Postdoctoral Fellowship was terminated. My grant focused on testing interventions to address online misinformation and I was 8 months into a two year appointment.

The fealty that corporate chieftains are showing the new president is a worrying sign for our economy.
