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

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

We often hear from reviewers: "what about demand effects?" So we developed a method to eliminate them. Something weird happened during testing: We couldn’t detect demand effects in the first place! (1/8)

Summary of design and results from our three studies. (A: Design) Each study used a similar experimental design, measuring both positive and negative demand in an online experiment, with three commonly-used task types (dictator game, vignette, intervention). Our experiments had ns ≈ 250 per cell. (B: Results) Observed demand effects were statistically indistinguishable from zero. The plot shows means and 95% confidence intervals for standardized mean differences derived from frequentist analyses of each experiment and an inverse variance-weighted fixed-effect estimator pooling all experiments (solid bars). Prior measurements of experimenter demand from a previous dictator game experiment (de Quidt et al., 2018; standardized mean difference from regression coefficient) and a meta-analysis primarily including small-sample, in-person studies (Coles et al., 2025; Hedge’s g statistic) are also shown for comparison (striped bars). The main text includes Bayesian analyses that quantify our uncertainty.
