Another 'This is a marathon!' papers - happy to see this out! 🤗💥🎺With brilliant co-authors @kieranmepham.bsky.social & @cstadtfeld.bsky.social, we propose a set of measures to quantify polarization in society and study how our entrenched beliefs may lead to entrenched social networks and vice versa.

We would be excited to apply, calibrate and validate the measure using other data sets in which researchers have measured both individuals’ attitudes towards multiple policy items and interpersonal sentiments. If you know of such data, please get in touch!

Change in network polarization in two communities. Ideological polarization is slightly present and stable, while the degree of relational polarization appears to increase over time.

We measure change in network polarization in a community of undergraduate students. It is significantly present but rather low. However, relational polarization tends to increase over time. Homophily and social influence appear to be among the network mechanisms explaining these trajectories.

An empirical network collected in a undergraduate cohort with perceived friendship relations (dark ties) and individuals' positive and negative attitudes (green and red ties) towards multiple policy issues (yellow squares)

Relational polarization relates to the degree to which individuals are preferentially socially tied to other with whom they agree. For example, to what degree does the level of agreement on climate change issues or private weapon use affect individuals' tendency to interact and socialize?

Example networks with different degrees of relational and ideological polarization.

Ideological polarization refers to the degree to which individuals generally tend to agree or disagree with others on multiple issues simultaneously. For example, to what degree do individuals’ attitudes towards renewable energy predict their attitudes towards wealth tax?

Network Polarization: In a new paper with @kieranmepham.bsky.social‬ and András Vörös we propose a measure of societal divisions that considers ideological and relational aspects separately, using concepts from network science.

Relational hyperevent models for the coevolution of coauthoring and citation networks Abstract. The development of appropriate statistical models has lagged behind the ambitions of empirical studies analysing large scientific networks—system

For example, in our study Rock and Dubstep are close in terms of social ties even though they are rarely listened to by the same person.

Social ties shorten relational distances between cultural genres—connected individuals make distant genre pairs more proximate.

Analyzing a large online network, we find that musical genre boundaries blur when considering social ties. Even if people do not listen to a specific musical genre themselves, they might be socially close to someone who does, bringing those genres closer in the social space.

🎶 New paper with Xinwei Xu & Alessandro Lomi in Poetics on the "dual clustering of tastes and ties".
Distances between cultural genres aren't just about what you like (tastes)—they're shaped by who you are connected to (ties).
