In 2016 Geoffrey Hinton said “we should stop training radiologists now" since AI would soon be better at their jobs.

He was right: models have outperformed radiologists on benchmarks for ~a decade.

Yet radiology jobs are at record highs, with an average salary of $520k.

Why?

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

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 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...
Variations in climate change belief systems across 110 geographic areas - Nature Climate Change
Climate beliefs do not exist in isolation but form an interconnected network known as a belief system. This study analyses the density and inconsistency of belief systems and their associations with informational and socioeconomic factors to inform effective climate change communication strategies.

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!

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.

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.

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.

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.

People organize in groups and contagions spread across them, meanwhile groups can evolve as people adaptively move in response to the spread. Here, authors show how keeping key dynamical correlations ...
