New paper out: "The puzzle of Ideography" (target article @BBS ). Why is it so hard for humans to communicate with pictures that represent ideas, not for words? And are we getting better at doing this? psyarxiv.com/7pd5m/ A thread ⬇

It's a privilege to engage with an expert like @JoHenrich on a question as important and foundational as the role of culture in perception. But @DorsaAmir and I think this thread gets several key details wrong, both bigger-picture and finer-grained. Here's how (🧵):

Let's review. Game on. The question: Is there evidence that population-level variation exists in susceptibility to visual illusions? @DorsaAmir & @chazfirestone wrote a fascinating paper to which I will reply in two storm tweets. I see major problems. Storm 1 coming...

🎆New paper alert!
Me & @Alexey_Koshevoy revisit the law of abbreviation, a nearly universal correlation between word frequency and brevity.

5/ The takeaway? 💡
Efficiency isn’t necessary or sufficient to explain the law of abbreviation. Instead, a general brevity bias is sufficient to account for it.

Zipf’s law of abbreviation explained by a simple cultural evolutionary model:
- no pressure for efficiency
- general pressure for brevity applying to all words
- explains the weak correlation between frequency and brevity
- explains heteroskedasticity

HBES mourns the death of one of its founders, John Tooby (1952-2023), on Fri Nov 10th. John was co-director of the UCSB Center for Evolutionary Psychology with Leda Cosmides, and was HBES President (1999-2001). He had an enormous impact on the field & will be sorely missed.

I humbly did some maths and graphs on this preprint from @acerbialberto, which has a clear and important message, I believe. Also he's a great writer!
Also features this gorgeous saddle-node bifurcation👇

Just uploaded an heavily updated version of a preprint (basically a new manuscript), now with @benoitdecourson mathematical models!
