We test this by considering a cross-linguistic dataset of locomotion naming 🏃‍♀️💃🚶
We find that even in this challenging dynamical multi-modal domain, systems of semantic categories across languages are significantly efficient

2️⃣ Bilinguals employ two different category systems, but in practice they converge on systems that differ from monolinguals. Is this a sign bilinguals depart from efficiency to satisfy other (e.g., learnability) constraints? No, bilinguals still maintain optimality!

4/n

1️⃣ We've previously shown converging evidence that semantic categories across languages achieve near-optimal compression via the Information-Bottleneck principle. But how do languages become near-optimal?
By revisiting human iterated language learning data, we find that
