You can define culture many ways obviously, but my point is that you can distinguish behaviors that move with the individual to other places and those that are part of stable equilibria, where one's choice only makes sense in light of others' choices. The latter are like n-player "Stag Hunt" games. https://en.wikipedia.org/wiki/Stag_hunt

As an example, Singapore accepts a lot of Malays and Chinese every year (and most people are Chinese), but the country has "an obsession with queueing" (https://www.todayonline.com/singapore/no-time-wait-line-star...) and is very orderly w/r/t traffic laws and such.
