We had a new tutorial on representational similarity analysis come out recently. Led by @xallysie.bsky.social with Ruoying Zheng and @chujunlin.bsky.social

This technique lets you compare patterns across diff types of measures (eg correlate correlation matrices), super flexible

Our new study shows that living in states with higher levels of structural sexism was associated with worse cardiovascular disease outcomes for both men and women, especially for diabetes and stroke.

Immigration raids during Trump II have increased daily student absences by 22 percent in the California Central Valley, with largest increases among the youngest students.

This is an impressively bad photo haha, but the work seems really interesting! Any chance of getting access to the poster somehow?

That said I've since learned that we are basically brute forcing a math proof of the law of large numbers and approaching population parameters. Convinced this is true, but for me the tool far easier to use practically and we still use it internally all the time. Other approaches in the paper
5/n

Initially an internal tool we made a good while ago to answer some qs and guide data collection. But we made it public with a little write up. And then that white paper got more citations than much of my real empirical work. So seemed useful to folks, and we decided to write it up.
4/n

Having stable ratings trims out some error from your overall model, optimizes data collection so you don't waste money, and helps you plan how many ratings to collect for x rating (for example)
3/n

For people who collect a bunch of ratings, combine them in some way (avg), and then analyze those averages. These avg ratings are "stable" when more ratings wouldn't meaningfully change the avg. When more raters agree on a rating, stability is achieved faster, but this varies by stim and trait.
2/n

We have a new tutorial out in Social Cog methods issue, a resampling tool we made in R that basically tells you when some average is "stable" and can be used to guide data collection or test hypotheses related to variance. Quick explanation here

There is a robust link between intergroup contact & reduced prejudice, but does contact actually cause a reduction in prejudice?

Across multiple longitudinal data sets (N > 20,000), very few people reported increased contact AND reduced prejudice.

Hostile and benevolent sexism are both on the decline in 1,097 studies, N = 339,740 since 1996.

Note that "3" on these scales is already a neutral response. Even bigger progress in countries with more hostile sexism.

New paper out in Journal of Experimental Social Psychology! 🎉

How do we figure out who will accept or reject us in a new group?

We show that people generalize relational value across friendship ties—forming a network gradient of approach & avoidance.

A little hectic to collect it all in a semester, but I think a pretty fantastic learning experience for the students, so would recommend CREP you teach a Research Methods class: osf.io/wfc6u/ 3/3
Collaborative Replications and Education Project (CREP)
CREP’s mission is to provide training, support, and professional growth opportunities for students and instructors completing replication projects, while also addressing the need for direct and direct+ replications of highly-cited studies in the field. Hosted on the Open Science Framework

This was one of those 2010 papers where some results are entirely unbelievable. Read a paragraph, cohen's d =3.69 on some outcome. My class teams failed to replicate about 10 times alone. 2/3

Using this to plug how I think CREP is a great framework if you teach a Research Methods class, a number of my students ended up as authors, which they found pretty cool 1/3
