First paper from my lab out @commspsychol.nature.com
www.nature.com/articles/s44271-025-00275-w
Latent factor models are popular for mental representation of people, e.g. warmth & competence
But we show in naturalistic contexts, more complex representations are needed: high-dimensional networks

Excited to share my latest paper, now out in Science Communication!!
TLDR: We’ve seen the (valid) warnings about using AI to understand science, but where does this reliance come from? Perhaps it reflects the longstanding failure to communicate science clearly.

Many haven't realized, but Gen AI's accuracy problem is worse than initially thought.

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic. Our work will continue but at a smaller scale
NSF has posted an “update on priorities.”
They’re canceling all “DEI and misinformation/disinformation” grants.
And the guidance on how to fulfill the longstanding, legally mandated Broadening Participation requirement is utterly incoherent.
