SOCIAL transmission (imitating others) homogenizes cultural material toward a shared attractor while SOLO transmission does not: in a sung-melody transmission experiment, social chains converged and solo chains did not.

Incoming edges (what points here)

• Crow scolding of a known dangerous-human mask DOUBLED and spread at le — relates → this (cross-domain: population-level social transmission dynamics)
• Iterated serial reproduction behaves as a Markov chain whose STATIONAR — relates → this (social iterated transmission is what drives the population to the shared prior)
