This gets to some important points. There was always something cold, even chilling, about Brockman's "Edge" culture. That feeling still pervades some scientific circles. There's a real problem here that won't go away with Epstein.

Are female economists treated differently than males in academic seminars?

These authors wanted to know whether gender shapes how scholars are treated when presenting research.

So they built a massive dataset of 2,000+ economics seminars, job talks, and conference presentations from 2019–2023...

New episode, first of 2026!! 🎉🎙️

A deep dive into metaphor with @sflusberg.bsky.social!

Metaphors delight, provoke, captivate, shock, and galvanize us. What does it say about the human mind that we simply can't escape them—and frankly don't want to?

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉

We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟

Thrilled to see this paper out, two years after starting our collaboration at @divintelligence.bsky.social
My co-authors and I are happy to present our framework "Collective Intelligence as Collective Information Processing (CIP)."

Here we propose decomposing different information processing mechanisms to unify disparate phenomena traditionally classified as "collective intelligence."

🚨Excited to share our new theoretical framework to classify and spark mechanistic inquiries into various forms of collective intelligence!

Soon to be published in @cognitionjournal.bsky.social

How likely are you to invest in a new business? Ask your partner to marry you? Move to a new country?

A new model by SFI External Professor Paul Smaldino and colleagues explains how wealth, experience, and environment shape our risk tolerance — and how those effects persist across generations.
Personal risk tolerance has sweeping implications for how societies evolve
How much risk is any individual willing to take on? That depends, in part, on their individual resources and environment, which shape the learning strategies that influence their personal proclivity t...

I wanted dinner recommendations so I scraped 13,000+ London restaurants and accidentally discovered Google Maps is running a shadow economy. Anyway here's a dashboard and a political economy thesis: open.substack.com/pub/laurenle...
How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it
I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.

My main takeaway from this one:

Dog domestication is a singular "natural experiment" in brain evolution, one that we're just starting to understand. It's a bit bonkers more neuroscientists aren't working on it.
It was long thought that domestication leads to reductions in brain size. But as we understand dog brains better, the truth is proving more complicated—and more interesting.

Just one of the topics discussed in our latest episode, w/ @erinhecht.bsky.social!

Which processes underlie collective intelligence in naturalistic human groups?

In new work led by Valerii Chirkov, we show that payoff selectivity is key in transforming a group of individuals into an intelligent collective 🤝🧠

Fun article about “outsider” scientists and their breakthroughs.

“Academia filters most funding, publishing, and hiring decisions through senior insiders, which favors ideas within existing paradigms.”
