Very lucky to have been able to collaborate on this Annual Review piece on luck with @fabriberna.bsky.social, William Foley and @l-sage.bsky.social. We propose that the role of luck in life can be upper-bounded with machine learning and lower-bounded by adding up causal effects of random events.

🧵 New WP! w/ @selcanmutgan.bsky.social Most segregation research examines neighborhoods, schools, or workplaces separately. But do individuals' exposure align across domains and persist over the life course? We fill this gap using 27 years of 🇸🇪 data. Pre-print: osf.io/eunwc_v1 (1/5)

Chapter 5: @martinarvidsson.bsky.social, Hedström, Jarvis & @marckeuschnigg.bsky.social on the intersection of Analytical Sociology and Computational Social Science. Computational tools are most powerful when used to identify and test mechanisms, not just describe or predict aggregate patterns.

Do ordinary Republicans and Democrats really avoid each other in everyday life? In a new working paper with Delia Baldassarri, we present descriptive and experimental evidence to challenge the view that partisanship drives the formation of social relationships. osf.io/preprints/so... 1/15

New paper out with @kchihaya.bsky.social and @eduardotapia.bsky.social. We show how a tendency to move near kin can preserve patterns of segregation, using a combination of discrete choice models and micro-simulations applied to the case of immigrants and their descendants living in Stockholm.

Nice new paper in PNAS providing further evidence that random/long ties help social contagions — even many that would be labeled "complex contagions" www.pnas.org/doi/10.1073/... @davidlazer.bsky.social

This is a fairly technical but highly relevant paper on how we can model complex systems at various levels of detail without losing causal content. Think gas: instead of tracking every molecule, we can focus on big-picture properties like temperature and pressure. www.auai.org/uai2017/proc...

#IC2S2 2025 is just around the corner! July 21–24 in Norrköping, Sweden. Bookmark tutorials, keynotes, and must-see sessions and connect with fellow attendees using #IC2S2. Full program here: www.ic2s2-2025.org/program/ See you in Norrköping! 🇸🇪

The deadline for submissions to the special issue honoring Richard Breen has been postponed to August 31st

As some of you guessed, the two models are statistically indistinguishable. The answer is Model 1, but there was no way to tell from the data. I was very surprised when I first saw this. Here we show that this confounding of heterogeneity and reinforcement is general: www.pnas.org/doi/10.1073/...

🧵1/8 In our new #OA article, we studied the drivers of ethnic school segregation. Research on segregation often points to parental preferences, but what if it's not just about what parents want, but also what options they actually have? 🔗 doi.org/10.1093/esr/jcaf027
