New paper in Political Psychology (@ispp-pops.bsky.social) tested the Social Identity Model of Collective Action during Gen Z protests in Madagascar. They show SIMCA's relevance for post-action social harmony This is also the first data exclusively from Madagascar published in the journal!

Screenshot of article title and abstract. The title is, "Navigating social change and social harmony: Testing SIMCA in Gen Z collective action in Madagascar and its role in reconciliation processes". The abstract is, "The Social Identity Model of Collective Action (SIMCA) effectively predicts collective action and social change, but has been less examined in emerging movements and non-WEIRD contexts. This research had two aims: to test SIMCA during the Gen Z mobilization in Madagascar, a largely online movement that culminated in the overthrow of the government in October 2025; and to examine how SIMCA variables relate to post-action activism and reconciliation. Study 1 (N = 959), conducted during the governmental transition, tested SIMCA—including national identification, Gen Z identification, perceived injustice, collective efficacy, and morality—on online collective action support, intention, and participation. Study 2 (N = 258), conducted post-transition, examined associations with activism intention, reconciliation, and forgiveness. Gen Z identification and morality were consistently associated with collective action and activism intention, whereas perceived injustice was primarily linked to ongoing collective action. Collective efficacy showed mixed associations. In contrast, national identification emerged as a key factor of post-action forgiveness. These findings suggest that SIMCA variables are involved not only in social change but also in post-action social harmony. They highlight the distinct roles of politicized and non-politicized identities, underscoring the importance of conceptualizing collective action as a temporally and contextually embedded process."

I'm thrilled to share that I have defended my dissertation, "Falling Short? Testing the Causal Relationship Between Downward Mobility and Populist Support." A lot of existing work (including some of my own pre-testing) links downward mobility to support for populist politics. 1/4

Every year, I swear I'm not going to wait until the last minute to figure out SPSP submission plans, and yet here we are. It's June 16th, and I just started reaching out to people last week 😅

I keep trying to make my dissertation acknowledgements section shorter, but I just have so many dang people to thank. So I guess I'm just gonna have like a 4 page acknowledgements section 😂

✨New paper out @nature.com ✨ For 8 weeks around the 2024 US election, we randomly assigned 2,000 people to use social media algos we built ourselves. Do engagement-based algorithms amplify intergroup, moral & emotional (IME) content—and does that distort how we see political norms? 🧵🔗 👇

Only half joking when I say one crucial piece of wisdom I've gained throughout the course of my 20s is that you'll pretty much never regret being the girl in sneakers instead of heels on a bachelorette trip

here is something I've found while working on something related: the extent to which we can predict a college freshman's "political ideology" (liberal/moderate/conservative) from their father's & mother's occupations almost tripled from 1976 to 2010:
