Despite the presence of increasing pressure towards globalisation, thecoexistence of different cultures is a distinctive feature of humansocieties. However, how multiculturality can emerge in a population ofindividuals inclined to imitation, and how it remains stable undercultural drift, i.e. the spontaneous mutation of traits in thepopulation, still needs to be understood. To solve such a problem, wepropose here a microscopic model of culture dissemination which takesinto account that, in real social systems, the interactions areorganised in various layers corresponding to different interests ortopics. We show that the addition of multiplexity in the modeling of oursociety generates qualitatively novel dynamical behavior, producing anew stable regime of cultural diversity. This finding suggests that thelayered organisation of social influence typical of modern societies isthe key ingredient to explain why and how multiculturality emerges andthrives in our world.
