In Ywadee's culture, a person's head is considered sacred. There is no law against the touching of heads in Ywadee's country, but almost everyone knows that it is unacceptable to do so. Under these circumstances, which term do sociologists use for this belief?

I think this is called culture shock. This gesture of touching the head of the Ywadees is something new to the other cultures. People outside their culture believes that this is wrong but for the Ywadees, this is their belief and way of life. For a sociologist, they believe that there is no right or wrong in culture. People should respect other cultures.
