Why does a worse candidate win? Or an inferior song dominate?

New article with @alexgelas.bsky.social, @pantelispa.bsky.social & Gaël Le Mens.

We show that often once A becomes even slightly more popular than B, people choose A much more often.

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.

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.

Wide Social Influence and the Emergence of the Unexpected: An Empirical Test Using Spotify Data Article: Wide Social Influence and the Emergence of the Unexpected: An Empirical Test Using Spotify Data | Sociological Science | Posted October 23, 2025

5/ Examining the macro-dynamics, we used agent-based simulations integrating prior models of homophily and decoupling, showing that network composition matters: a sufficient presence of partial-overlap ties is crucial for widespread diffusion of novelty and the emergence of the unexpected.

4/ We find support for the hypothesized homophily trade-off: (a) stronger taste overlap → stronger peer influence, but also (b) stronger overlap → less exposure to novel content.

3/ To test this, we analyzed 1M Spotify users. Treating playlists as documents and artists as words, we used topic modeling to infer musical tastes, peer overlap, and exposure novelty. To distinguish selection & influence, we compared un/treated users with similar musical tastes—the key confounder.

2/ At the core is a hypothesized homophily trade-off: too much taste similarity→influence but no exposure to novelty; too little similarity→exposure to novelty but weak influence. Partial overlap strikes the balance, both exposing and influencing individuals toward content outside their repertoire.
