Every summer, parades in Northern Ireland bring tension. In our new study, we combine data on 55,000+ parades, surveys, & fieldwork to show how “contentious rituals” affect intergroup relations. All thanks to my amazing co-authors: Kit Rickard, Giovanni Hollenweger & @kristinmbakke.bsky.social

This summer, Professor Ruth Ditlmann led the "Randomized Intergroup Interventions" workshop at the Hertie School, funded by Volkswagen Stiftung. They explored how intergroup conflicts, prejudice, and social divisions influence political outcomes and policy preferences.

Great summary of our study with @arolsenarchives.bsky.social and its message: “For ordinary citizens, the takeaway is clear: Don’t just read about history—help preserve it. Your contribution creates ripples […] potentially helping to build stronger, more inclusive societies.” shorturl.at/Urozd
