Do you know that? You think you are acting according to common sense and therefore have a common basis, only to stumble across cultural differences. This can lead to unexpected complications, especially in intercultural cooperation. What seems self-evident to us may seem strange or even irritating in other cultures.
Even a dinner together can be exciting. If I assume that I get a menu that I can read and choose my meal according to my cravings, this is the case in Germany or Australia, for example. Everyone places their order directly. In India, I am wrong in this assumption. The ordering process itself is an essential part of the joint dinner. Everyone is asked what they would like. Even if everyone seems to agree on everything, it is a slow process until you really know what everyone wants, who will share which dishes with whom and how many dishes will be enough for everyone. Vegetarian or no pork, spicy or very spicy, masala dosa or butter chicken? It is very unusual to say directly what you want or to disagree with someone else’s choice. All common sense? Probably not.
Are you aware of the findings on parenting practices and ideas that Sara Harkness and Charles M. Super have highlighted in their article “Themes and Variations: Parental Ethnotheories in Western Cultures”? And here we don’t even have to go into the East-West difference, but in Western countries alone there are serious differences in understanding. Babies in the Netherlands sleep two hours more a day than in the USA. That was a surprise to me. According to Harkness and Super, parents in the Netherlands placed great importance on their children getting enough rest or sleep during the first years of childhood in order to raise them to be calm, happy and self-regulated children. The American parents, on the other hand, described their child’s sleep behaviour as innate and developmental. The practices and beliefs observed in each case presented themselves as part of a cultural system and not as a result of the parents’ intensive study of the latest findings in child-rearing. Common sense is no help in intercultural understanding here either.
We are all cultural beings by nature and are strongly influenced by the culture in which we grew up. Common sense is therefore a very local matter. In intercultural cooperation, we would do well to reflect on our self-evident assumptions and not apply them as a generally valid basis.
