Prior experimental work, where participants reproduced sets of non-linguistic sequences in transmission chains, shows that this pr...

New paper with @inbalarnon.bsky.social and @simonkirby.bsky.social! Learnability pressures drive the emergence of core statistical properties of language–e.g. Zipf's laws–in an iterated sequence learning experiment, with learners’ RTs indicating sensitivity to the emerging sequence information.

One research direction of my group will be the evolution of European literature, relying on my ERC starting grant. Another direction will be the cultural evolution of films, music & other diverse artforms. I'll be hiring postdocs & PhD students starting in March 2026, so there will be job posts! 3/3

The building of the Max Planck Institute for Empirical Aesthetics in Frankfurt

I got wonderful news: I was granted a position of Max Planck independent group leader at the MPI for Empirical Aesthetics ⬇️ (@ae.mpg.de) in Frankfurt, which I'll join in early 2026. It's a huge honor: being trusted with academic freedom offered by MPG. My group will study the evolution of arts. 1/3

Societal crises disrupt long-term increases in stress, negativity, and simplicity in US Billboard song lyrics from 1973 to 2023 - Scientific Reports Scientific Reports - Societal crises disrupt long-term increases in stress, negativity, and simplicity in US Billboard song lyrics from 1973 to 2023

US song lyrics have become more negative in the last 50 years, but societal shocks (like 9/11 and COVID) corresponds to *attenuation* of this trend.

Today, we published a paper on the strength of language universals (if language has X, it also has Y) given spatial & phylogenetic autocorrelation in @nathumbehav.nature.com ! It is a cool research project, led by the brilliant Annemarie Verkerk at @uni-saarland.de

If someone knows that Venus is the only planet in the Solar System that rotates clockwise, will they also know what Earth’s only natural satellite is? What about which planets have no moons at all?

thanks!

Interesting! Curious to know what

Just out - "Art Beyond Cognition: Reframing Neanderthal art through social connectivity and cultural transmission" by Straffon & Tennie

Too bad — and in it makes sense, in hindsight, given the weaknesses of cognitive dissonance reduction as a theory. Still, on literary merits alone, When prophecy fails remains a gem of a book.

Academics in Assyria in the 7th c BC complain that admin is preventing them from doing research and teaching

It is time to abandon student evaluations of teaching

Comment by Gordon Hodson (@gordonhodsonphd.bsky.social)

PDF: rdcu.be/ef9y5

In this commentary, I argue that student-based teaching evaluations are problematic bc

✳️ systematic biases (e.g., racism, sexism)
✳️ poor construct validity
✳️ undermine standards and learning

We should evaluate teaching as seriously as we do research. Or don't do teaching evaluations.

Your chilly sneer
Of cold command
Your trunkless legs
Upon the sand
Once awed the Persian, Turk,
And Damascene

A pedastal
Beside your smirk
Proclaims “Look up,
You lazy jerk!
Behold the mighty work
Of great
Jolene.”

Unearthing the Nature of Knowing Research reveals how people process information, how they acquire—and sometimes reject—knowledge, and how that compares to artificial intelligence systems’ abilities to do the same.

Excited to see our research highlighted in @psychscience.bsky.social Observer!
With @oliviermorin.bsky.social , @hugoreasoning.bsky.social , and Thomas Dheilly, we explored how people infer others’ knowledge: even from a single answer, they can estimate how much someone knows about a topic!
