I’m going for a bit of a running theme here, but as I mentioned in this article, the roleplay between native and foreign inhabitants is under constant pressure due to normalcy. The article below from Aeon may actually highlight why the cultural differences are so hard to overcome.
Drawing on such research, Cimino’s automatic accrual theory suggests that hazing provides an important solution to a recurring adaptive problem faced by our species during our evolutionary history: how to accurately assess the intentions and quality of new group members.
Hazing then seems to be important as a universal test of loyalty. Not only a rite of passage, but also a bill of health on the qualities you have as a person. To reject whatever went before and accept whatever comes now. By that logic would more extreme “national” hazing rituals allow foreigners to be more accepted?
Somehow I doubt it.
