IB-social-homogenizes
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.
Observed quantities
3,424 melodies; 1,797 participants; social chains homogenize, solo chains do not

- relates to Iterated serial reproduction behaves as a Markov chain whose STATIONARY distribution equals the transmitters' shared prior: chains started from 2.63, 4.19 and 5.76 cm all converged to the same value within about 20 transmissions. a large behavioral instance of convergence to a shared prior under social transmission
- relates to Crow scolding of a known dangerous-human mask DOUBLED and spread at least 1.2 km over 5 years, with LINEAR (non-saturating) growth — a saturating/plateau model was statistically rejected. cross-domain: population-level social transmission dynamics
