Why do we so easily miss the importance of shared beliefs or culture?. Sociology

Culture is the belief shared by groups of people. It could be on shared gender, customs, values, ethnicity or even objects. For example, a Christmas tree can be considered a shared ceremonial belief. It can also demonstrate the way a group of people think, practices and behavioural patterns, or views. For example, Chinese people stand very close to others in public spaces. It is a norm that society is used to, and Norms that you are used to are neither right nor wrong, just different. But it can cause conflict if that person from China is standing too close to someone in the Western world.
