Very cool interactive story, @jstonge.bsky.social! "[...] real social cascades aren't simply branching processes with fixed rules." A self-reinforcing mechanism is what we propose in a recent piece led by the one and only @lhd.bsky.social.

Our Physical Review Letter looks at how to get power-law distributions of cascade size without tuning or self-organization to criticality by allowing cascades to improve in quality and jump over gaps or dead-ends TL;DR complex-stories.uvm.edu/friends-funn... Paper: journals.aps.org/prl/abstract...

🚨 Excited to share a new paper 📃, years in the making, with Zach Wood. We propose that human evolution is characterized as an Evolutionary Transition in Inheritance and Individuality (ETII). Explainer and OA paper below:

We love this research profile on Vermont Complex Systems Institute core faculty @juniperlov.bsky.social 🐙 www.linkedin.com/posts/uvm-vc...

A survey of >99k people (110 regions) shows the Global North has denser belief networks, while the Global South has looser connections Inconsistency appears in areas (eg Mid East), where support for fossil fuels conflicts with support for renewables/climate policies www.nature.com/articles/s41...

It might start as a joke, belief, or rumor, easy to dismiss. But then it twists, builds momentum, and spreads like wildfire. Why do some ideas die out while others go viral? A new study by researchers from the University of Vermont and the Santa Fe Institute offers answers: santafe.edu/news

New job ad: Assistant Professor of Quantitative Social Science, Dartmouth College apply.interfolio.com/172357 Please share with your networks. I am the search chair and happy to answer questions!

🐒🕸️ New preprint! Confused about how to model animal social networks? ASNA can be confusing—but also full of opportunity. We break down 5 common misunderstandings in animal social network analysis and share solutions from behavioural ecology, anthro, stats, & network science. Hope it helps! A 🧵

Hello, Bluesky! We're excited to relocate here from X. You can also follow us on LinkedIn: www.linkedin.com/posts/uvm-vc...

There's amazing work on group effects in higher-order networks, but not a lot of connections to social ontology, collective action, and group selection. Led by @jstonge.bsky.social with expert guidance of @rharp.bsky.social we reviewed and formalized these connections. arxiv.org/abs/2507.02758

Defining and classifying models of groups: The social ontology of higher-order networks arxiv.org/abs/2507.02758

A common narrative in the U.S. links a city’s political leanings with its level of racial bias. These assumptions are often too simple, suggests a new study by SFI's Andrew Stier and Brandon Ogbunu. Nearly 40% of cities analyzed do not conform to partisan expectations. santafe.edu/news-center/...

1/5 In a comment published in NPJ Complexity, SFI @sfiscience.bsky.social post-doc Andrew Stier and I ask a critical question: "What is the relationship between voting patterns in American cities and implicit racial bias?" We find that the story is...complicated. www.nature.com/articles/s44...

New work led by the great @giulioburgio.bsky.social. A detailed math model to track correlations within and across groups in higher-order networks. We also get to study adaptive hypergraphs, which self-organize as sparse or dense graphs to control a contagion. www.nature.com/articles/s41...

Today is the deadline to let us know of your interest to participate in the Complex Networks Winter Workshop 2025. Come join us for a week of science in a winter wonderland: old monastery, Québec city, the week before Christmas. vermontcomplexsystems.org/events/cnww/

For those of you at #SIAMDS25 in Denver, come check out @lhd.bsky.social and my Minitutorial! We'll be covering higher-order networks: when to use them, how to model dynamics with them, and how to implement with open-source software. Don't miss it! Details here: meetings.siam.org/sess/dsp_pro...

Hear me discuss our new paper written with the inimitable Laurent Hébert-Dufresne and colleagues! @lhd.bsky.social #Complexity #Physiology #Governance www.nature.com/articles/s44...

We’re hiring two postdocs at UC Davis and Cornell for research on collective intelligence and creativity. This project will use large-scale online experiments to study how groups become smarter and more creative through self-governance. ⅓

On this day in 2023, the Vermont Complex Systems Institute (vermontcomplexsystems.org), TGIR Center (www.med.uvm.edu/tgircobre/home) & @sfiscience.bsky.social joined for an event on interacting contagions Our work, "One pathogen does not an epidemic make," is now online: arxiv.org/abs/2504.15053

This paper is now published. www.nature.com/articles/s44...

Ties that bind! Such a cool study.
