Now that the fever of NetSci is gone, just a kind reminder that we have our newest research out at Communications Physics, led by @miguelagoncas.bsky.social with @anxosanchez.bsky.social 🙌🏼🙌🏼

Andreia Sofia Teixeira @asteixeira.bsky.social · Jun 3

So happy to see this published! Led by @miguelagoncas.bsky.social , with me and @anxosanchez.bsky.social , proving that the dynamical process driving the evolution of an empirical social
network is stationary, and that the network itself is in dynamical equilibrium.

7/8 And more beautifully: we can use simple mathematical models to describe this type of complex human social behavior.

6/8 Why does this matter? Because if a network is in equilibrium, a single network snapshot can reveal stable dynamical patterns. That validates tools like Exponential Random Graph Models, usual in non-longitudinal settings. Huge for social science!

Miguel A. González-Casado @miguelagoncas.bsky.social · Jun 3

5/8 We argue this behavior is rooted in the way in which humans allocate their cognitive resources to create functional relationships able to cover their social necessities, and in the competition between the mechanisms that drive the network evolution.

Miguel A. González-Casado @miguelagoncas.bsky.social · Jun 3

4/8 People constantly form and break ties, leave and join the network, and still all network snapshots are statistically equivalent to one another. This implies that what matters is not who is in the network, but the rules governing how relationships evolve.

Miguel A. González-Casado @miguelagoncas.bsky.social · Jun 3

3/8 It means that despite all the complexity, the temporal evolution of the network can be described by simple mathematical models and, more importantly, its behavior can be predicted with very high accuracy.

Miguel A. González-Casado @miguelagoncas.bsky.social · Jun 3

2/8 They are not! In our last work we analyze the empirical evolution of a social network, and we provide evidence that relationship networks can exhibit a behavior akin to equilibrium dynamics in the statistical physics sense. What does this mean?

Miguel A. González-Casado @miguelagoncas.bsky.social · Jun 3

1/8 How do networks of social relationships evolve over time? This evolution is driven by a complex interplay of cognitive, emotional, and social factors. It’s only natural to assume that such complexity would make this dynamics highly unpredictable. But…

I have co-authored many papers but with this one I believe we are contributing a qualitative step ahead to understand social networks. Wouldn't have been possible were not for the true forces behind this work, @miguelagoncas.bsky.social and @asteixeira.bsky.social. Thank you so much!
