This gets a lot of play in UG and early grad methods classes but SO little attention in actual practice. I mean, we think about it, yeah, but not very rigorously.

One year later - my reflections on what's happened to US science since the National Science Foundation grant terminations last year. The problem of misinformation isn't going away, but our ability to study and understand it is under attack. 1/ 🧪 www.tennessean.com/story/opinio...

In this research, we found that individuating information dominates social group information when forming impressions about members of newly learned social groups. This dominance was observed both on self-reports *and* more automatic measures *despite* conditions favoring group-level impressions.
