Brendan Nyhan

Dartmouth College political scientist known for research on misinformation correction and belief updating, who commented on Costello, Pennycook & Rand's 2024 AI-debunking study for The New York Times when it was first published. Matters to this vault as the one person, anywhere in the Costello/Pennycook/Rand conspiracy-persuasion research lineage, reported to have independently reproduced one of its findings: he told Retraction Watch that he and his students "have reproduced the paper's results in two independent experiments at Dartmouth College in New Hampshire" — with no co-authorship on either Costello paper.
