According to decades of behavioral experiments, humans defy logic.

Maybe that's not irrationality; maybe it's better math waiting to be found. Or just to be used to describe non-classical decisions, w/o need for quantum brains.

By replying to Elise below, we could generate a nice thread.
Hey complexity and complexity-adjacent people:

What are some of your favorite pop-sci books? Are there any you've had your eye on but haven't had a chance to read yet?

They can be new or old. I'd just love to know what y'all are reading!

The seven sisters were literally dancing over the full moon light.

Not the best conditions for taking pics, but I tried anyway. I can confirm conditions were not good: their blue lights got destroyed by interference with the moon ones.

Cooperation isn’t weakness, it’s strategy.

Axelrod’s rules remind us: fairness, reciprocity and humility often outcompete envy and cleverness.

In complexity, often simplicity wins.

Thinking we’re the peak of civilization, right?

Well, 3,000 years ago early Maya communities built a landscape cosmogram (a vast earthly map of the cosmos) without kings, armies, coercion.

Collective imagination and cooperation shaped order in their universe. ✨

The cosmogram of Aguada Fénix built over the landscape between 1050 and 700 BCE rivaled the extents of later Mesoamerican cities.

TL;DR: Even the most advanced language models crumble on first-person false beliefs, showing sharp accuracy drops and revealing that their “understanding” of others’ minds is still shallow pattern mimicry, not genuine epistemic reasoning.

In the meanwhile, you can help me by describing this image: what's that?

What connects molecules, ecosystems, brains and societies?

Exactly 1y ago, I captured that question in this video, showing how simple mechanisms generate the complexity of life and behavior.

Now heading towards the 3rd birthday of #ComplexityThoughts: unbelievable.

A microscopic organism can survive the vacuum of space: yet our infrastructures collapse under a summer storm.

Why? 👉 Because structure isn’t enough.
Resilience depends on functionality.

And we need a lot of network science to grasp it.

Revolutionary ideas.
Thinking of patenting my favorite method for ranking researchers: reading their papers and deciding whether they are good.
Hilariously bad idea. In my subfield author lists are almost always alphabetical!

Really?!?

Did we need this at all?

When will academia end its obsession with indices?

They've fueled quantity over quality for decades, leading to publish-or-perish, authorship games, data fabrication,...

Come on 🤦

Eventually, I did it.

Nice to read again the history of the attempts in the last weeks. Now, I am almost satisfied with the result: still something to fix, though.

Not the easiest session.

If you are curious to know what it means to take pictures from home, this should give a good idea

Oops I did it again.

I could not resist: perfect sky after 2 rainy days; no clouds now; just in plain sight from my backyard.

Fingers crossed @scrutacieli.bsky.social

In the '30s of the past century, the Sicilian physicist Ettore Majorana wrote an article about the value of statistical laws in physics and in social sciences. A pioneering non-technical work.

I am wondering if successive ('40s-'50s) “sociophysics” papers are related.

It has just recommended me to read this paper:

Facts:

* I'd love to have a paper with @netscience.bsky.social but I haven't
* There is no Multilayer Network Epidemiology

Urgent: can someone at the 🇺🇸 White House check if we’re facing an epidemic of exoplanets?

Where will this lead? Are we safe? Should we flatten the curve before it spreads?

Did you know that a simple proof that the speed of light is finite, the universe had a beginning and is expanding, is that the night sky is dark?

This is known as Olbers’ paradox, which puzzled astronomers for centuries.
